(Cambridge International, 2021) These ‘other factors’ could be environmental, social and/or cultural. This shows that biological psychologists do not ignore other influences on behaviour, cognitions and emotions, just that their primary focus is on the impact of biological factors. 1.1 Dement and Kleitman (sleep and dreams) ▲ Figure 1.1 An EEG measures electrical activity in the brain. It can be used to monitor time spent in different sleep stages (e.g. REM versus NREM) Psychology being investigated Sleep During sleep, the body is inactive. Conscious awareness is temporarily halted. Five sleep stages have been identified using electroencephalography (EEG). Each stage is characterised by differing brain-wave activity (see Figure 1.1). » Stages 1 and 2: light sleep; easily woken. » Stages 3 and 4: deeper sleep; brain waves have higher amplitude and lower frequency than brain waves in stages 1 and 2. » Rapid eye movement (REM) sleep: lower amplitude/higher frequency brain waves, similar to wakefulness; the eyelids move quickly but other muscles are paralysed; dreaming is common. Ultradian rhythms Ultradian rhythms are bodily cycles that repeat more than once every 24 hours. » During the night, we move through several 90-minute sleep cycles. » Earlier in the night, the cycles include a higher proportion of non-REM (NREM) sleep. » Later in the night, we spend more time in stages 1, 2 and REM sleep. STUDY TIP Before revising each study, briefly read through the description and list any methodological terms with which you feel less confident. Review these in Chapter 5 before you begin. Reviewing the study should help to reinforce and consolidate your understanding. Using key terms like ‘reliable’ and ‘objective’, in the right context, will improve your written work. Dreams are subjective memories of our experiences during sleep. Background » Kleitman conducted sleep research using his relatives as participants for many years. » In 1953, his student, Aserinsky, used an EEG to identify REM and NREM sleep. » Kleitman and Aserinsky also found that people woken in REM are more likely to report dreams than those woken in NREM. » Dement and Kleitman wanted to find a reliable and objective way to measure whether a person is dreaming, using biological evidence rather than verbal self-reports. 6 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 6 14/08/23 7:19 PM 1 The Biological approach Aims 1 To investigate whether dream recall is more common in REM than in NREM sleep. 2 To investigate whether participants can accurately estimate the duration of their dreams. 3 To investigate whether eye movements (vertical/horizontal) correspond with dream content. 4 To investigate whether there is a correlation between the duration of a REM sleep episode and the number of words (the narrative) used to describe any dreams experienced. Methodology Research methods and design: experiment with repeated measures design (aims 1–3) and correlation (aim 4). Data collection techniques: self-report, interview. Variables: Independent variables – whether the participants were woken: » during REM or NREM sleep (as shown by the EEG) » following 5 or 15 minutes of REM sleep » following REM sleep with mainly vertical, mainly horizontal, mixed or limited eye movements. Dependent variables: » whether a dream was reported or not (quantitative) – dream has to be described in detail to be counted » perceived duration of dream: – initially participants were asked to report dream length in minutes – later the procedure was changed. Participants were instead asked whether they had been dreaming for 5 or 15 minutes (fixed/forced choice question, quantitative data) » verbal description of dream content/narrative (qualitative data); number of words used (quantitative). Sample: Size: seven men, two women (five studied in depth, four to confirm results). Demographic: from Chicago, USA. Sampling technique: not stated in the journal article. Overview of procedure Participants slept: » in a quiet, dark room at the University of Chicago » with electrodes placed near the eyes and on the scalp: – wires were tied together to stop them from becoming tangled – the EEG machine was in an adjoining room. Participants were woken: » several times each night » to self-report all the dependent variables (see above) using a bedside recording device. The researchers: » chose when to wake the participants using the EEG and a timer » listened to the self-reports from the adjoining room Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 7 7 14/08/23 7:19 PM » occasionally entered the sleep room to interview the participant about their dream – they never revealed information about sleep stage or direction of eye movements when questioning the participants. Controls » Participants all: – abstained from alcohol and caffeine on the day of the study – reported to the laboratory at their normal bedtime. » The same loud doorbell was used for all awakenings. » The positioning and number of electrodes was standardised (2–3 near the eyes and on the scalp). Ethical issues » Confidentiality and privacy were maintained. – Participants were referred to using their initials. – Dream content was not paired with their initials. NOW TEST YOURSELF 1.1Outline the use of interviewing to gather qualitative data in this study. [2] 1.2 Give one key feature of experiments as a research method, using an example from this study. [2] SKILLS BUILDER Describe the use of correlations as a research method in this study. SKILLS BUILDER Suggest one or more reasons why Dement and Kleitman used an EEG in this study. [3] ‘Suggest’ means to present ideas or considerations based on your knowledge and understanding of psychology. Little elaboration is required as you are not asked to explain or justify your reasons. You may explain what the EEG was measuring and why that was necessary in this study. You could also give strengths of using scientific equipment like an EEG. [4] To answer this question, you need to understand the difference between correlation and experiment. Refresh your memory of correlations on page 69 if you need to. Consider planning your answer carefully before you start writing. For example, what is a correlational study? How did the researchers operationalise their co-variables? What was the nature of the relationship? Why did the researchers use correlation not experiment for this part of the study? Results REM sleep never occurred immediately after sleep onset. All participants had regular REM sleep periods throughout the night: » one REM period every 92 minutes (range 70–104 minutes) » average REM sleep duration of 20 minutes (range 3–50 minutes) » longer REM sleep periods later in the night. ▼ Table 1.1 Sleep stage and dream reporting Sleep stage when woken Frequency of dream reports REM 80% NREM 7% ▼ Table 1.2 Accuracy of dream duration estimates 8 Duration of REM before waking Accuracy rate of dream duration estimates 5 minutes 88% 15 minutes 78% Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 8 14/08/23 7:19 PM 1 The Biological approach One participant (DN) had a lower accuracy rate of only 65 per cent: » He underestimated dream length. » He was only correct 50 per cent of the time when woken after 15 minutes. ▼ Table 1.3 Eye movements and dream content Eye movement Dream content Mainly vertical Looking up and down while: » operating a hoist at the bottom of a cliff where people were climbing » climbing a series of ladders » throwing basketballs into a net Mainly horizontal Watching two people throwing tomatoes at each other Mixed » Talking in a group of people » Searching for something » Fighting with someone Limited eye movement Looking into the distance while driving a car NOW TEST YOURSELF 1.3 State one difference between REM and NREM sleep using evidence from this study. [2] Correlation coefficients for REM duration and length of dream report (number of words) for each participant: » ranged from +0.40 to +0.71. » the average was +0.58. Conclusions » Dreams are more likely to be reported in REM than NREM sleep. » Dreams are experienced in real time – dream length and REM sleep duration match. » Eye movements in sleep are not random; they match dream content. » The subjective experience of dreaming can be measured objectively using EEG to identify REM sleep. Evaluation ▼ Table 1.4 Strengths and weaknesses of Dement and Kleitman Strengths Weaknesses Reliability – the procedure was standardised Validity – some data was discarded as recordings (e.g. participants were always woken using the same loud were too muffled and dreams could not be accurately doorbell), meaning the study can be replicated to test for transcribed. reliability. Objectivity – the use of quantitative EEG data (e.g. amplitude and frequency of brain waves) removed bias when deciding whether sleep was REM or NREM. Generalisations – only nine people were studied (and only five in detail); ages and occupations were not provided so individual differences may have affected results. Issues and debates Application to everyday life Understanding typical patterns of sleep and dreaming is important: » Psychologists can identify people whose sleep and dreams are unusual. » People are more likely to receive suitable treatment/support to improve sleep quality. Nature versus nurture » Support for nature: all participants demonstrated ultradian REM/NREM sleep cycles and dreamed more during REM than NREM. This suggests these patterns are innate and may help us to survive. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 9 9 14/08/23 7:19 PM » Support for nurture: dream content was diverse; differing life experiences affect what we dream about and may affect the duration of REM sleep. SKILLS BUILDER Dement and Kleitman investigated ultradian rhythms. Outline one finding from this study that supports the nature side of the nature–nurture debate. [2] This question has a stem – that is, a sentence before the question. Sometimes stems are helpful as they remind you of details from the study. However, the question does not say you have to refer to it. 1.2 Hassett et al. (monkey toy preferences) Psychology being investigated Play » Play is a universal, voluntary behaviour observed in the young of most species. » Activities are often similar to adult behaviours. » Play may be adaptive. Sex differences » Types of play and toy preferences differ between human infants with differing sex chromosomes. » For example, XY boys typically prefer cars to dolls, whereas the reverse is true of XX girls. Socialisation » Many people believe these differences are due to society’s differing expectations of girls and boys. » Children learn these expectations through socialisation. » Hassett et al. believed biological factors are also important. STUDY TIP Give dual-coding a try. This means making notes in both a verbal and visual way. You could draw a diagram of the monkey enclosure to help to consolidate the procedure. Include the different areas (inside/ outside), cameras, toys, etc. Swap your diagram with a classmate. Ask them to add labels and anything you have missed. When you revisit the study, cover your diagram and try to redraw it from memory. The role of hormones Sex hormones (e.g. testosterone, oestrogen) affect brain development. This may explain why boys and girls prefer toys that can be played with in different ways. Background » Hassett et al. (2008) were interested in research into congenital adrenal hyperplasia (CAH). For example, XX girls with CAH prefer stereotypically masculine toys, even when encouraged to play with stereotypically feminine toys. » Previous monkey research found that masculine toys were played with more by male than by female monkeys; likewise, female monkeys showed a strong preference for feminine over masculine toys. » As monkeys are not affected by societal expectations about gender-appropriate behaviour, Hassett et al. believed sex differences in toy preferences are determined by nature more than nurture. Aims 1 To investigate sex differences in monkey toy preferences when presented with a stereotypically feminine toy and a stereotypically masculine toy. 2 To provide support for the role of nature (not nurture) in shaping sex differences in human toy preferences. 10 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 10 14/08/23 7:19 PM 1 The Biological approach SKILLS BUILDER Explain why the study by Hassett et al. is from the Biological approach. [2] The command term ‘explain’ means that you need to think about reasons why the study by Hassett et al. is part of the Biological approach. First, think about key terms/phrases from the main assumptions of the approach, such as ‘working of the brain’ and ‘hormones’. Which words/phrases link best to the ‘psychology being investigated’ and/or the background of Hassett et al.? Your first sentence could state a reason and the second sentence could show detailed knowledge of the study to support the reason you have given. Methodology Research methods and design: experiment with independent measures design. Data collection techniques: » Seven 25-minute controlled, non-participant, covert observations of monkeys in their normal outdoor enclosure. » A behavioural checklist was used by two observers to analyse the video recordings. Variables: Independent variable – whether the monkey was male or female. Dependent variable – whether monkeys spend longer (in seconds) interacting with the wheeled toy or the plush toy. Other information collected – age (juvenile, adult) and social rank (determined through observation of grooming). Sample: Size: 135 juvenile and adult monkeys; 14 excluded (previous participation in hormone research); 39 infants excluded (looked too alike to accurately record sex). Demographic: the monkey troop had lived together at a research centre for 25 years. Sampling technique: opportunity; the analysis included data from 23 females and 11 males, each of whom interacted with the toys at least five times. Overview of procedure » Different pairs of wheeled and plush toys were used in each observation (e.g. wagon/ teddy, truck/Scooby-Doo). » Observers recorded: – duration of toy interactions (in seconds) – specific behaviours using a behavioural checklist (e.g. holding, dragging). » Unclear behaviours were discussed between the two observers. Controls » Monkeys were kept indoors while toys were positioned. » Toys were placed 10 m apart. » Toy positions were counterbalanced – that is, whether wheeled/plush toys were on the right/left side of the enclosure. Ethical issues » Guide for the Care and Use of Laboratory Animals guidelines were upheld, such as appropriate housing: – appropriate housing (25 m2 outdoor enclosure with a temperature-controlled indoor area) – constant access to water, daily monkey chow and fresh fruit and vegetables. » The research was regulated by the Emory University Institutional Animal Care and Use Committee. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 11 11 14/08/23 7:19 PM NOW TEST YOURSELF 1.4Outline two reasons why some of the monkeys were not included in the final sample. [2] 1.5 Give one weakness of the use of a behavioural checklist in this study. [2] 1.6 Give one strength of the use of controlled observation as a way of collecting the data in this study. [2] SKILLS BUILDER Give one strength of using animals as participants in this study. [2] The command term ‘give’ means you do not need to give a reason for your strength. Think generally about why psychologists might prefer to use animals rather than humans in their research (see page 79). As the question says ‘in this study’, you must relate your point specifically to Hassett et al. For example, naming a controlled variable and showing how this would be impossible with humans. Results » 73 per cent of the males preferred wheeled toys, 9 per cent preferred plush toys and 18 per cent showed no significant preference. » 30 per cent of females preferred the plush toys, 39 per cent preferred the wheeled toys and 30 per cent showed no significant preference for either toy. » The data from the monkey observations were compared with data from a similar study using children. Figure 1.2 shows the similarity between the two sets of results. – Both sets of results show that males significantly prefer masculine to feminine toys and, although there is a difference in the preference of females for feminine toys, this is far less pronounced, especially in the monkeys. Sex difference in play with stereotypical masculine and feminine toys in human participants Sex difference in total frequency of interactions with plush and wheeled toys by rhesus monkeys 500 14 12 Total interactions (mean seconds) Play time (mean seconds) 400 300 200 100 10 8 6 4 2 Male Female Sex of human subjects Male masculine toys Female Sex of monkey subjects feminine toys ▲ Figure 1.2 Bar charts showing the similarity between the findings of Hassett et al. (right) and a similar study conducted with human infants (left) Conclusions Toy preferences in both humans and monkeys are influenced by hormonal sex differences. These biological differences lead males and females to prefer different activities. Differing activity/play preferences lead to sex differences in cognition and behaviour. 12 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 12 14/08/23 7:19 PM 1 The Biological approach Evaluation ▼ Table 1.5 Strengths and weaknesses of Hassett et al. Strengths Weaknesses Reliability – the well-operationalised behavioural checklist meant behaviours were consistently coded in the same way. Objectivity – the researchers who analysed the videotapes were very familiar with the monkeys, which could lead to observer bias. Validity – use of unobtrusive video cameras meant that behaviour was likely to be more spontaneous and unaffected by human presence. Generalisations – Eight of the 11 male monkeys were juveniles, and the only high-ranking male in the troop did not interact with any of the toys. Issues and debates Application to everyday life » The findings may be helpful to people who design and market toys, as well as parents and other adults when buying toys for children. » Empathy and language skills could be developed in boys through play with wheeled toys which have expressive faces. » Visuospatial skills could be developed in girls using toys with moving parts that can be used to create a social situation, such as a school bus with dolls for the driver and children on board. Nature versus nurture » The findings support nature over nurture. » Differences in toy preference result from hormonal differences between the sexes. » Males showed stronger sex-typed toy preferences than females. » Toy preferences were also affected by social rank. Role within the group also affected time spent interacting with toys. Sex was not the only important factor. Use of children and animals in psychological research » Conclusions from animals were extrapolated to children. » Using animals allowed the researchers to control the environment, increasing validity. » From a very early age, children start to learn about social norms for play and toy preferences based on gender (e.g. from advertising, observing their peers). Using animals allowed the researchers to examine the effect of biological factors (e.g. hormones) without the confounding variable of previous social and cultural experiences. SKILLS BUILDER Fenella thinks the findings of Hassett et al. support the nature side of the nature– nurture debate, but her friend Meera is not so sure. Outline why you think either Fenella or Meera is correct, using evidence from the [2] study. This type of question requires careful reading of both the stem (the sentence about Fenella and Meera) and the actual question. Focus on evidence to support either Fenella or Meera, but not both. 1.3 Hölzel et al. (mindfulness and brain scans) STUDY TIP Have you tried the Leitner technique? This technique relies on spaced repetition, an evidence-based strategy to improve knowledge retention. Watch online videos and check websites such as The Learning Scientists (http://learningscientists.org) to find out more. The technique involves revisiting material either daily, every other day or every week, depending on how well you remember it. You can use it to learn details, such as which brain structures increased or decreased in grey matter concentration (GMC) in this study. ▲ Figure 1.3 Mindfulness could be used to develop non-judgemental attitudes in the workplace, helping team members to work together more productively Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 13 13 14/08/23 7:19 PM Psychology being investigated Mindfulness » Mindfulness is a stress-reduction technique used to improve wellbeing through developing awareness of the present moment and encouraging compassionate, non-judgemental attitudes. » Biological psychologists are uncertain how Mindfulness-Based Stress Reduction (MBSR) enhances wellbeing, but neuroimaging reveals which brain structures may be involved. Localisation of function » This is the idea that specific brain structures are responsible for specific behaviours/cognitive processes. » This study used magnetic resonance imaging (MRI) and voxel-based morphometry (VBM) to examine which brain structures (e.g. hippocampus, insula) undergo structural plasticity (changes in neural tissue) following MBSR training. Background » Meditators have significantly more grey matter in the hippocampus and insula than non-meditators. For example, functional magnetic resonance imaging (fMRI) research found the hippocampus to be active during meditation. » Changes in wellbeing may be linked to increases in grey matter concentration (GMC) following mindfulness/meditation practice. Aims 1 To investigate changes in GMC following an eight-week MBSR programme. 2 To identify specific brain structures that undergo change following the eightweek MBSR programme. Methodology Research methods and design: 1 Longitudinal experiment with mixed design: – Repeated measures - brain scans were conducted at the beginning and end of an eight-week period. – Independent measures - findings from the MBSR group were compared with a no MBSR control group. (See page 58 to refresh your knowledge of experimental designs.) 2 Correlations: The researchers analysed the correlation between the amount of time that participants engaged in mindfulness practice (time in minutes) and increases in GMC. Data collection techniques: MRI: » Scans were conducted two weeks before the first MBSR session and at the end of the eight-week training programme » A 3D digital brain model was created for each participant, using 128 sagittal (top to bottom) images. Self-reports: » The Five Facets of Mindfulness Questionnaire (FFMQ) was used to measure 5 key aspects of mindfulness that have been found to be positively correlated with wellbeing. » Participants rate 39 statements from 1 (‘never or very rarely true’) to 5 (‘very often or always true’). 14 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 14 14/08/23 7:19 PM 1 The Biological approach Variables: Independent variables: » MBSR: the experimental group (6 males, 10 females; mean age: 38) attended 2.5hour weekly group meetings for eight weeks and one 6.5-hour training day. – Sessions included yoga, sitting meditation and body scanning (a relaxation technique). » The control group (11 males, 6 females; mean age: 39) did not attend these meetings (independent measures) but were on a waiting list for future MBSR. » MRI brain scans before and after the first MBSR session and at the end of the eight-week study period. Dependent/co-variables: » VBM (see page 15) was used to measure grey matter concentration throughout the brain, but specifically in the hippocampi and insulae (quantitative data). » Mindfulness was measured using the FFMQ (quantitative data). Additional co-variable: time spent on mindfulness exercises between training sessions (daily diaries used to collect self-reported data). Sample: Size: 33; experimental group: 6 males, 10 females; control group: 11 males, 6 females. Demographic: right-handed, healthy adults, age 25–55, no regular medication, limited meditation experience. Sampling technique: opportunity sample recruited from four MBSR courses held at a mindfulness centre in New England, USA; all were referred or self-referred for stress. Overview of procedure » Stage 1: participants received MRI scans and completed the FFMQ two weeks before the first MBSR meeting. » Stage 2: eight weeks of MBSR for the experimental group only, who were also given a 45-minute audio recording of mindfulness exercises to practise at home. » Stage 3: participants received MRI scans and completed the FFMQ two weeks after the final MBSR meeting. Controls » Participant variables were controlled by: – using repeated measures design, i.e. testing the same people twice at the beginning and end of the study – checking that there were no significant differences between the two groups in terms of key variables, such as age and educational background. » Order effects were controlled by using a ‘no MBSR’ control group to determine how much of the change in GMC at scan 2 was spontaneous/natural and how much was due to the independent variable (the MBSR programme). Ethical issues » Participants in the experimental group gave informed consent – agreeing to aim to participate in all meetings, complete ‘homework’ exercises and record duration in daily diaries. » MBSR fees were reduced to thank all participants. » Participants with claustrophobia and/or metallic implants were excluded to protect them from psychological and physical harm caused by the MRI scanner. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 15 15 14/08/23 7:19 PM SKILLS BUILDER Explain how one finding from the study by Hölzel et al. (mindfulness and brain scans) supports one of the assumptions of the Biological approach. NOW TEST YOURSELF [2] It would be good for your chosen finding to match a specific concept mentioned in one of the main assumptions of the approach. For example, ‘The experimental group showed increased GMC in the left hippocampus and posterior cingulate compared with the control group.’ This matches ‘the workings of the brain’ mentioned in the first assumption. The next sentence may link your chosen finding more clearly to the assumption. For example, ‘This shows that changes in behaviour and cognition (like becoming more aware, observant and less judgemental) may be caused by increased GMC in these structures.’ This would show a good knowledge of the specific brain structures and three of the five facets of mindfulness. SKILLS BUILDER Arthur aims to investigate changes in grey matter concentration in a group of six art students before and after a 16-week observational drawing class. He expects to see differences in key brain structures, including the cerebellum and prefrontal cortex. Write a suitable non-directional (two-tailed) alternative hypothesis using [2] Arthur’s aim. 1.7Outline two features of the questionnaire used to measure mindfulness in this study. [2] 1.8 Explain how the use of a control group helped to increase validity in this study. [2] 1.9 Give two reasons why Hölzel et al. is an example of an experiment with a longitudinal [4] design. This question asks you to show understanding of the difference between directional and non-directional hypotheses, and alternative and null hypotheses (see Chapter 5). Make up possible hypotheses for all 12 of the core studies. Then rewrite them as null hypotheses and/or switch from directional to non-directional. Remember, when you are writing an alternative, non-directional hypothesis, you will state that ‘There will be a difference’ in the results for each group or condition, but you will not state the direction of this difference – for example, which group/condition will have the higher score. Ensure that your hypothesis includes both conditions/groups of the independent variable. Also, where possible, ensure you have used information from the extract to operationalise both the independent and the dependent variables (i.e. give the units of measurement). Results The average time spent on mindfulness exercises was: » 27 minutes per day » 22.6 hours over 8 weeks (SD = 6.3 hours) ▼ Table 1.6 Time (in minutes) spent on MBSR exercises over eight weeks Mindfulness exercises Mean Standard deviation Body scan 699 217 Yoga 327 194 Sitting meditation 332 211 Following MBSR training, the experimental group showed: » significant improvement in three of the five facets of mindfulness: acting with awareness, observing and non-judging » a significant increase in GMC in the: – left hippocampus – posterior cingulate cortex – temporoparietal junction – cerebellum 16 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 16 14/08/23 7:19 PM 1 The Biological approach » no significant correlation between GMC and time spent on mindfulness exercises or the five facets of mindfulness. The control group showed: » no significant improvement in any of the five facets of mindfulness » a significant decrease in GMC in the posterior cingulate cortex. Conclusions » Regular mindfulness practice can lead to localised structural changes in grey matter concentration, in structures including the left hippocampus and posterior cingulate cortex. » Changes in these structures may underpin the wellbeing benefits of mindfulness, as they have been previously linked to learning, memory, emotion regulation and perspective-taking. » Previous research on the insulae was unconfirmed. Changes in this structure may take more than eight weeks. Evaluation ▼ Table 1.7 Strengths and weaknesses of Hölzel et al. Strengths Weaknesses Reliability – the FFMQ is highly reliable. For example, Validity – changes in GMC in the experimental groups may the correlation between the eight questions on have resulted from increased social interaction at the MBSR ‘acting with awareness’ was +0.87. group. This confounding variable was not controlled. Objectivity – analysis of quantitative data from VBM is objective as it is conducted via computer software. Generalisations – findings may not be representative of people older or younger than 25–55 or with fewer years of education. Issues and debates Application to everyday life Integration of regular opportunities for daily mindfulness in the workplace could lead to improved wellbeing. This may also lead to increased productivity and fewer days lost to ill health. Nature versus nurture The impact of both nature and nurture are supported. » Nature: localised increases in GMC were correlated with changes in three of the five facets of mindfulness. » Nurture: environmental experiences (e.g. MBSR group attendance) affect wellbeing. SKILLS BUILDER Hölzel et al. measured grey matter concentration throughout the brain before and after participation in an eight-week MBSR programme. Suggest one situational and one individual factor that could affect the extent to which participants in the experimental group experienced changes in grey matter concentration. [4] This book includes ideas to help you to think about how the issues and debates at AS Level can be applied to each of the 12 studies. However, you may sometimes be faced with a question on an issue/debate which has not been covered. These questions can be fun as they offer an opportunity to think creatively rather than scour your memory for missing facts. Individual factors relate to the person. They are characteristics or traits that may lead the person to perform differently from others who do not possess that characteristic or trait. Situational factors relate to the circumstances or context in which a person’s behaviour is observed. For example, a person’s age may influence changes in GMC (individual factor). Furthermore, environmental stressors, such as noise or overcrowding in the setting in which mindfulness is practised, may decrease the extent of GMC change (situational factor).

These processes can also help to explain behaviour and emotion. (Cambridge International, 2021) 2.1 Andrade (doodling) Psychology being investigated Memory STUDY TIP Memory is: » the encoding, storage and retrieval of information, including sights, sounds and smells » the process of retaining this information over a long period of time. Incidental memory is the memory of information you have not been asked to remember/are not focused on. Information is therefore remembered unintentionally. Attention Attention is the process of focusing on a particular piece of information or task. » There is a limit to how much information we can process at any one time, so we are selective in which information we focus on. » Selective attention is the process of focusing/concentrating on information that is important while blocking out irrelevant information. Andrade’s study uses several important key terms for example, incidental memory and monitoring accuracy. Create a matching game in which you have to match key terms to their definitions. Write the terms and definitions onto squares of paper, mix them up and see if you can put the pairs back together. Background » Doodling may impair performance by moving concentration away from the primary task. » However, doodling may help us to concentrate better: – especially on tasks that are not very interesting (i.e. low arousal) – by increasing arousal and alertness and reducing daydreaming, which decreases concentration on a task. Aims 1 To investigate whether doodling while listening improves attention/ concentration. 2 To investigate whether doodling while listening improves recall. Methodology Research method and design: laboratory experiment with an independent measures design and random allocation. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433_CH02.indd 19 19 18/08/23 6:53 AM Data collection techniques: » Monitoring task: Participants listened to a pretend telephone message about a party, including names of people and places (see below). – They had to pay attention and write down the names of people who were able to attend the party (monitored information). » A surprise memory test. Variables: Independent variable: whether the participants were allowed to doodle (shading lines of shapes on A4 paper) or not while listening to the pretend telephone message. Dependent variable(s): » Monitoring – accuracy: number of correct names (out of eight) – performance: correct names minus false alarms (wrong answers). » Memory for: – monitored information: number of correct names recalled (out of eight) after false alarms were deducted – incidental information: number of correct places recalled (out of eight). Sample: Size: 40 (35 women and 5 men); doodling condition: 20; control condition: 20. SKILLS BUILDER Outline why doodling may help people to concentrate on a task. [2] You could start by talking about how doodling inhibits (reduces) daydreaming. Then in the second sentence you could talk about how this improves performance by increasing arousal levels and alertness, meaning we are able to concentrate better on the task. Demographic: 18–55-year-olds; members of the University of Plymouth participant panel. Sampling technique: opportunity; participants had just finished another experiment. Researchers asked whether they would stay to complete another study hoping that this would increase the likelihood of boredom. Overview of procedure » Participants sat alone in a quiet, dull room and were given a sheet a A4 paper. This was either: – printed with rows of shapes to shade (the experimental group). – lined with no shapes to shade (the control group). » They were asked to listen to a 2.5-minute audio recording of a pretend telephone message » The message mentioned: – eight people who would be at the party – three people and a cat who could not come, called ‘lures’ – eight place names – a lot of irrelevant information. » Both groups had to write down the names of the people coming to the party on the A4 paper. » One minute after listening to the tape, there was a surprise memory test. Participants had to write down: – the names of the party-goers – the place names. Controls All participants: » heard the same 2.5-minute tape in the same room » were given standardised instructions before listening to the tape. NOW TEST YOURSELF 2.1Outline one difference between monitored and incidental information, with an example from this study. [2] 2.2 Describe how quantitative data was gathered in this study. [2] 2.3Outline one disadvantage of the way that doodling was operationalised in this study. [2] Half the participants recalled the names first and the other half recalled places first (counterbalancing) to avoid order effects. (Revise order effects and counterbalancing on page 59.) 20 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 20 14/08/23 7:19 PM 2 The Cognitive approach Ethical issues » Deception: Participants were told that they did not need to remember anything on the tape, which was not true. » Informed consent could not, therefore, be given. SKILLS BUILDER Suggest one strength of using counterbalancing during the surprise memory test. [2] The command term ‘suggest’ requires you to present ideas or considerations based on your knowledge and understanding of psychology. Think about a possible strength of using counterbalancing in Andrade’s study. For example, first, you could identify the strength (e.g. controlling order effects) and second, link it back to the study/surprise memory test. When you link back to the study, you may explain how counterbalancing would help improve the validity of the specific findings of this study, which is about doodling and memory.

Conclusions » Doodling improves concentration during boring listening tasks. » Doodling improves memory, even for information we have not intentionally tried to store. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 21 21 14/08/23 7:19 PM Evaluation ▼ Table 2.3 Strengths and weaknesses of Andrade Strengths Weaknesses Reliability – highly standardised procedure which can be replicated easily to test for reliability. For example, all participants listened to the same tape, in the same room, and they were given standardised instructions. Objectivity – misheard words (e.g. writing Greg instead of Craig) were counted as correct. The assumption that words have been ‘misheard’ rather than being incorrect makes the coding of answers subjective. Validity – Andrade checked whether any participants had Generalisations – there were more females (87.5 per detected the deception. A total of 18 per cent said that cent) than males (12.5 per cent), meaning that the they had. The data was re-analysed without their scores, findings should be generalised to males with caution. and the results were the same. Issues and debates Individual and situational explanations The study shows that: » attention/memory is affected by situational factors, such as being able to doodle » cognitive performance is not always fixed and stable » that parents/teachers/employers need to be aware that small changes in a situation can improve people’s performance. Application to everyday life » Benefits of doodling should be communicated to employers/teachers, etc. » It should not be assumed that people who doodle in classes/meetings are not concentrating. » People who find it hard to concentrate could be offered paper to doodle. This could improve their concentration on dull tasks. SKILLS BUILDER Penny is a manager at a local company. Her employees are struggling to concentrate in work meetings. Outline how the results of the study by Andrade could be applied to Penny’s company to help employees to concentrate. [2] The command term ‘outline’ means you do not need to go into great detail within your answer. Show your knowledge of the results of Andrade’s study and then how this can be applied to Penny’s company. You could talk about any result in the study, as long as you make it relevant to Penny and her employees. However, the results from the ‘monitoring’ part of the study are the most relevant to concentration. For example, Penny could provide paper and coloured pens in meetings to encourage doodling, as this could help the employees to focus more on what people are saying, but only if the meeting is boring. 2.2 Baron-Cohen et al. (eyes test) Psychology being investigated Theory of mind » Theory of mind is the ability to determine the mental state of ourselves and other people. » It is linked to social sensitivity and the ability to understand other people’s opinions or views. » There are two stages: – What? Identifying a person’s mental state. For example, ‘He feels sad … ‘ – Why? Understanding the context of that mental state. For example, ‘ … because he lost his ball’. 22 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 22 14/08/23 7:19 PM 2 The Cognitive approach » People with autism spectrum disorders often do not have a fully developed theory of mind. This is called a a theory of mind deficit. Social sensitivity » Social sensitivity is the ability to identify and understand social cues and contexts when interacting with others. » It refers to how well you can understand other people’s feelings. Background Measuring cognitive dysfunction » It is difficult to develop tests that are sensitive enough to detect cognitive dysfunction, especially for adults with typical intelligence but impaired social understanding. » Therefore, most tests are developed for children. The original ‘Reading the Mind in the Eyes’ test » This was a test for adult social sensitivity/theory of mind. » It included 25 photographs of eyes of famous actors. » Participants selected one of two words to best describe how the person in the photograph was feeling. » Adults with high functioning autism (HFA) or Asperger syndrome (AS) scored significantly lower than matched controls. STUDY TIP To better understand the evaluation points for this study, why not take the eyes test yourself. There are many websites where you can try it, such as https://docs. autismresearchcentre. com/tests/adult_part1. pdf. When completing the test, think about how it could be improved. ▼ Table 2.4 Problems with the original eyes test Problems with the original Eyes Test Solutions in the Revised Eyes Test Each item had only two possible answers; a score of 68 per Increased number of items from 25 to 36; increased cent or more was needed to be higher than chance alone. number of possible answers from two to four. Basic mental states were used (e.g. happy, angry); even very young children can identify these states. Only included complex mental states (e.g. contempt). Eye direction could be used to identify some mental states (e.g. noticing). These were not included in the new test. More female than male faces were included. The same number of male and female faces were used. The correct and incorrect (foil) answer options were opposites, such as sad versus happy, which was too easy. Similarity between the target word and the three foils was increased, making it more difficult. Words may not have been understood. The test was presented with a glossary. Aims 1 To investigate whether scores on the Autism Quotient (AQ) and the Revised Eyes Test scores are negatively correlated. 2 To trial the Revised Eyes Test with adults with high-functioning autism and Asperger syndrome as shown in Table 2.5. ▼ Table 2.5 Aims of Baron-Cohen et al.

Items were accepted if 50 per cent (of the 225 participants) selected the target word and no more than 25 per cent picked the same foil. » Four items were rejected, leaving 36 items on the Revised Eyes Test. The Revised Eyes Test » Participants took the Revised Eyes Test individually in a quiet room. » Groups 1, 3 and 4 completed the AQ. » Group 1 (HFA/AS) also identified the gender of the people in the photographs. » Participants could refer to the glossary to clarify word meanings. Controls » The same tests were taken in the same way (quiet conditions with glossary). » All items in the Revised Eyes Test were the same size, in black and white, with four options and three foils. Ethical issues Psychological harm: » A lack of understanding of the words/emotions may cause distress/ embarrassment. » People in Groups 2–4 who received extreme scores may need referral for more detailed assessment, especially for those with HFA/AS. SKILLS BUILDER For the study by Baron-Cohen et al., outline how two results support the aims of this study. [4] To answer ‘how’ the results link to the aims, choose one result and briefly describe it. Then link it back to the aims made by Baron-Cohen et al. As you are asked about two results, you need to do this twice. In this section, the aims and results are numbered. This is to make it easier for you to link each result to the relevant aim/part of an aim. It is worth revising in this way so you do not get them mixed up. NOW TEST YOURSELF 2.4 Describe how Baron-Cohen et al. chose the target words and foils for the Revised Eyes Test. [4] 2.5The research methods used in the study by Baron-Cohen et al. included experiments and correlations. Outline what is meant by a correlation giving an example from this study. [3] 2.6 Give one advantage of the use of a questionnaire as a way of collecting the data in this study. [2] Results 1 There was a negative correlation between the AQ scores and the Revised Eyes Test scores (–0.53) for all three groups. 2 2.1Group 1 performed significantly lower on the Revised Eyes Test than other groups. There were no impairments in the gender recognition task. 2.2Group 1 scored significantly higher than Groups 3 and 4 on the AQ. 2.3Although not significant, females scored higher than males on the Revised Eyes Test. 2.4 Males scored higher on the AQ than females. Conclusions The Revised Eyes Test: » is a more sensitive test for social intelligence than the original Eyes Test » can be used as a measure of severity of autistic traits due to the negative correlation with the AQ.

Objectivity – there was no interpretation needed for the data collected as the answers on the eyes test were either right or wrong. Generalisations – volunteer sampling means generalisations should be made with caution. Results may not be representative of adults with HFA/AS who do not attend support groups or read the NAS magazine. Issues and debates Individual and situational explanations » Individual explanation: autism is an individual difference between people that affects the ability to understand mental states from facial expressions. » Situational explanation: people with HFA/AS are better at recognising other people’s mental states in some situations more than others – for example, where there is less noise or fewer distractions or when they are given sufficient time. Application to everyday life » People with brain damage could take the Revised Eyes Test to detect social sensitivity deficits. Support could then be offered to help them to detect mental states in others. » The Revised Eyes Test could also be used in schools to target children who may benefit from interventions to improve theory of mind skills. SKILLS BUILDER Samuel is 15 and suffered brain damage in an accident. He struggles to understand people’s emotions and mental states at school and at his part-time job. Suggest two situational factors that could improve Samuel’s ability to understand emotions and mental states in others. [4] understand emotions and mental states. For example, you could identify noise as a relevant situational factor and link this back to Samuel by suggesting that reducing noise levels might increase his ability to focus on social cues from his co-workers.

(line-ups) Psychology being investigated Eyewitness testimony » The police may ask people present at the scene of an accident and/or crime to provide a description of what they saw/heard/smelt. » These descriptions may help the investigation and/or provide evidence that is later used in legal proceedings against the culprit(s). STUDY TIP It may be tempting to just read your notes over and over again, but this may not be that effective. Putting your notes into a different format will help you to process them at a deeper level than simply re-reading. If you enjoy learning by listening, you could read your notes aloud into a device such as your smartphone, so that you can listen to them at a later time. Research shows that listening to your own voice is more effective for revision than listening to an unfamiliar voice (Forrin and MacLeod, 2018). 26 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 26 14/08/23 7:19 PM 2 The Cognitive approach False positive responses In relation to eyewitness testimony (EWT), a false positive response is when a witness picks out a person from a line-up and says they were present at the crime scene when they were not. Pozzulo et al. suggested that this may occur in children due to social pressure rather than poor memory. Background » Children and adults produce similar correct identification rates from line-ups when the target is present (target-present line-ups), but even 13-year-olds struggle to correctly reject target-absent line-ups, leading to higher rates of false positive responses than with adults. » These errors may be due to social factors, such as social pressure, rather than cognitive factors, such as bad memory. » The desire to please the interviewer, who is often an authority figure, may also be a social factor that leads to higher false positive responses in children. Aims To investigate whether children: » are less able to recognise human faces than adults » make more false positive identifications than adults when faced with: – target-absent line-ups versus target-present line-ups – human faces and cartoon characters. Methodology Research method and design: Laboratory experiment with a mixed design: » Independent measures – two groups were compared: children and adults. » Repeated measures – all participants viewed both types of line-up with both types of face. Data collection techniques: » Questionnaire: the demographic and cartoon watching form measured variables such as the participants’ age, gender and time watching cartoons, familiarity with the target cartoons. » Participants had to identify the cartoon/person in the video (if present) by pointing on a PowerPoint (children) or a matching sheet (adults). Variables: Independent variables: » age: children (4–7-year-olds) versus adults (17–30) » type of target faces: familiar cartoon or unfamiliar human faces » type of line-up: target-present or target-absent. Dependent variables: » correct identification rates for target-present line-ups » correct rejection rates for target-absent line-ups. (Revise the difference between independent and dependent variables on page 57.) Sample: Size: 59 children and 53 adults. Demographic: 4–7-year-olds from three private schools in Canada; 17–30-year-olds from the Introductory Psychology Participant pool of an Eastern Ontario University. SKILLS BUILDER Describe the psychology being investigated in the study by Pozzulo et al. [5] The command term ‘describe’ requires you to make a series of distinct points. Revise the ‘psychology being investigated’ thoroughly. For Pozzulo et al. you could describe eyewitness testimony and false positive responses within your answer. You could make two distinct points about each, and then provide an example of one from Pozzulo et al. Sampling technique: not stated in the journal article. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 27 27 14/08/23 7:19 PM Overview of procedure The videos: » Participants individually watched four videos (in colour), each with a photo line-up: – Two featured familiar cartoon characters, Dora and Diego. – Two featured an unfamiliar human character, either male or female. » Next they completed a filler task in which they were asked, ‘What did the cartoon character/person look like?’ and ‘Do you remember anything else?’. Photo line-ups: » Next, participants viewed photo line-ups that included four tightly cropped black and white headshots. » Target-present line-ups included one target photo and three foils (people who looked similar). » Target-absent line-ups had four foils. » Participants were asked to point to the photo if the target was present, or another box if not. Controls » The four videos and the order of the faces in the line-ups were randomised for each participant to prevent order effects. Revise order effects and randomisation on page 59. » Standardised instructions were given to each participant prior to presentation of the photo line-ups. » All experimenters wore the same type of ‘professional-casual’ clothing. NOW TEST YOURSELF 2.7Outline the filler task used in the Pozzulo et al. study. [2] 2.8 Suggest one weakness of using laboratory experiments to study children as eyewitnesses.[2] 2.9Name two controls that were used in the Pozzulo et al. study. [2] Ethical issues » The researchers gained written informed consent from parents of all child participants and from all adult participants. » Participants were told that targets may not be present, so there was no attempt to deceive/mislead them. » All children were monitored for anxiety, stress and fatigue in order to minimise possible harm. This is important as children are less likely to exercise their right to withdraw. SKILLS BUILDER Xander and Toph are discussing the study by Pozzulo et al. Xander thinks the study used an independent measures design, but Toph thinks it used a repeated measures design. Using evidence from this study, explain one reason why Xander is correct and one reason why Toph is also correct. [4] The command term ‘explain’ means that you need to justify your answer, or give reasons why both Xander and Toph could be considered to be correct. In the world of research, the design used in Pozzulo et al. would be referred to as a mixed design. This is because some aspects are independent measures (e.g. looking for a difference in the skills of children versus those of adults) and other aspects are repeated measures (e.g. participants are asked about both human and cartoon faces). You need to show your understanding of both independent measures and repeated measures by explaining what these terms mean in the context of both this study (i.e. Pozzulo et al.) and with reference to Xander and Toph. Results Target-present line-ups » Children and adults were significantly better at identifying familiar cartoon characters than human faces. » Children performed much worse than adults when identifying human faces. ▼ Table 2.8 Success rate for identifying faces in target-present line-ups Familiar (cartoon) Unfamiliar (human) 28 Children 0.99 0.23 Adults 0.95 0.66 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 28 14/08/23 7:19 PM 2 The Cognitive approach Target-absent line-ups » Children had a significantly higher correct rejection rate when cartoon characters were used (0.74) compared with human faces (0.45). » Adults also performed significantly better with cartoon characters (0.94) compared to human faces (0.70). » Children’s rate of false positive responses was much higher than adults. Conclusions » As children were able to correctly identify cartoon characters in target-present line-ups, cognitive factors were not responsible for the lower success rate in target-absent line-ups. » Errors were caused by social factors – that is, incorrectly believing that the researcher wanted them to make a positive identification, no matter whether the child thought it was right or wrong. » Children are less accurate when faced with human actors and more likely to give false positive responses than adults. Evaluation ▼ Table 2.9 Strengths and weaknesses of Pozzulo et al. Strengths Weaknesses Validity – using repeated measures meant results were not affected by participant variables, such as having better/worse working memory skills. Reliability – although standardised instructions and procedure were used, the questions during the filler task were not exactly the same for everyone. This may have affected the participant on the line-up task, thus lowering reliability. Objectivity – the data obtained was quantitative. The participants were either right or wrong in their answers on the line-up task. Therefore, there was no room for interpretation/researcher bias. Generalisations – the findings may not be generalisable to participants from lower socioeconomic backgrounds as the children were all from private schools. The adults were also all from a university, suggesting higher than average intelligence. Issues and debates Application to everyday life » Eyewitness testimonies can be affected by the expectations of others, especially with child witnesses. » The findings could be used to develop police guidelines for interviewing child witnesses. This could reduce incorrect identifications, especially with targetabsent line-ups. Individual and situational explanations » When a target is present in a line-up of cartoon characters, adults and children are as accurate as each other. However, this is not the case for human faces. Individual characteristics such as age or memory may not be as important as situational characteristics such as familiarity. » The findings of the study suggest that situational factors such as social pressure (i.e. the perceived expectations of others) may explain why children are more likely to identify a suspect even in a target-absent line-up. Use of children in psychological research Young children are vulnerable to social pressure, so they were protected from harm by: » seeking parental consent as children cannot understand the risks of participation » telling them that they could change their mind and not get into trouble » conducting craft activities to put them at ease before the experiment started Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 29 29 14/08/23 7:19 PM SKILLS BUILDER Serena believes the findings of Pozzulo et al. support the situational side of the individual–situational debate.

Experiences and interactions with the environment shape our behaviour and these changes are directly observable. 2 We learn through the processes of operant conditioning, classical conditioning and social learning. This can be understood using the stimulus–response model. (Cambridge International, 2021) 3.1 Bandura et al. (aggression) Psychology being investigated Social learning theory New behaviours are learned by watching the behaviour of others (observational learning). » The person whose behaviour is observed is called the model; imitation of their behaviour is called modelling. » Learning may be spontaneous (without intention to learn). » Reinforcement (including vicarious reinforcement) increases the likelihood of learned behaviours being imitated. » Stages of observational learning include attention, retention, motivation and reproduction. Aggression » Aggression is an act of hostility with the intention of harming another. » It can be physical or verbal. STUDY TIP Goal-setting is an important skill for independent learners but monitoring your progress and revising your goals accordingly is even more important. Generate three specific, measurable, attainable and realistic targets to work towards while reviewing the next research study. Effective targets are time-bound so set a deadline to complete the work by. Background » Previous research showed that children imitate observed behaviour when models are present. Bandura wanted to know whether children would imitate observed aggressive acts in new settings when models were absent. » Parents tend to reinforce children’s ‘sex-appropriate’ behaviour (Fauls and Smith, 1956) so children may be more likely to imitate same-sex models. For example, boys may be more likely to imitate male models than females; and an aggressive male model may be imitated more than an aggressive female model. Aims To investigate whether observed behaviour is imitated in a new setting in the absence of the model, specifically to discover whether: » children observing an aggressive model exhibit more aggressive acts than children observing a non-aggressive model » children observing a non-aggressive model exhibit fewer aggressive acts than children who do not observe a model » children who observe same-sex aggressive models exhibit more aggressive acts than children who observe opposite-sex aggressive models » boys exhibit more aggressive acts than girls. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 31 31 14/08/23 7:19 PM SKILLS BUILDER Explain how the children’s aggressive behaviour was scored in the study by Bandura et al. (aggression). [2] Even short-answer questions like this one can be easy to misinterpret. You may find it helpful to read each question several times so you know what is expected. Refresh your knowledge on the scoring of children’s behaviour using time sampling in a structured observation on a behaviour checklist. You may also include details such as ‘recording behaviours every 5 seconds, providing 240 observations per child’ and ‘recording examples of imitative aggressive responses, partially imitative responses and non-imitative responses’. This would demonstrate that you are able to select relevant details from the study by Bandura et al. Methodology Research method and design: laboratory experiment with a matched design: » Each child was observed by the experimenter and a nursery teacher. Their aggression level was rated using four five-point scales. » Children were put into groups of three with children of a similar aggression level to each other (matched). Next, one child was randomly allocated to the control group, one to the aggressive model group and one to the non-aggressive model group (see below). Data collection techniques: » Observation: covert, non-participant, structured, controlled; observed through a one-way mirror using behavioural categories. (Revise the different types of observation on page 67 and time sampling on page 74.) » Time sampling: a 20-minute session divided into 5-second intervals, giving 240 response ‘units’. Variables: Independent variables: » control group (no model), aggressive model, non-aggressive model » sex of model (same or opposite to the child) » sex of children (male or female). Dependent variable: number of behaviours (out of 240 maximum) in each of the following response categories: » imitative aggression responses – physical aggression, verbal aggression, nonaggressive verbal responses » partially imitative responses – mallet aggression, sits on Bobo doll but does not behave aggressively » Non-imitative aggressive responses – punches Bobo doll, non-imitative physical and verbal aggression, aggressive gun play. Sample: Size: 36 boys and 36 girls. NOW TEST YOURSELF 3.1 Describe how a structured observation was conducted in the study by Bandura et al. [3] 3.2 In the study by Bandura et al., the participants were matched before allocating them to the experimental and control groups. a Describe how the children were matched in the study by Bandura et al. [2] b Give one advantage of matching participants in this way.[2] Demographic: 3–6 year-olds (mean age: 4 years, 4 months); attended Stanford University nursery school. Sampling technique: not stated in the journal article. Overview of procedure Phase 1: Modelling » The child played with potato prints and stickers and the adult played with a tinker toy set. The room contained a five-foot inflatable Bobo doll (adult-size) and other toys. 32 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 32 14/08/23 7:19 PM 3 The Learning approach » The model then behaved either in a non-aggressive way or in an aggressive way: – aggressive group: hits Bobo with a mallet, sits on Bobo and punches his nose, throws and kicks Bobo; verbal aggression included ‘sock it in the nose’ and ‘kick him’ – non-aggressive group: the model played quietly – control group: no model present in the playroom » After ten minutes, the child was taken to another room by the experimenter. Phase 2: Mild aggression arousal NOW TEST YOURSELF 3.3Outline the ‘aggression arousal’ procedure. [3] » The second room contained attractive toys, including a fire engine, doll set and spinning top. » After two minutes, the experimenter told the child the toys were for other children and took the child to a third room. Phase 3: Test for delayed imitation » This room contained aggressive toys (e.g. mallet) and non-aggressive toys (e.g. tea set) and a three-foot Bobo doll (child-size). » The child was left alone. His/her behaviour was observed for 20 minutes through a one-way mirror. Controls » Toys in rooms one and three were placed in the same positions. » The model’s actions were always the same, in the same order and for the same length of time. » Observations were made by two independent observers. – Observer data was compared (to assess inter-rater reliability) and showed correlations in the 0.9 range. (Revise inter-observer reliability on page 81). Ethical issues » Psychological harm: the children witnessed aggressive behaviour and were mildly provoked; the expected outcome was to imitate aggression. » Confidentiality: children were not named in the article, but the nursery the children attended was named. SKILLS BUILDER Bandura et al. used a covert observation in their study. Explain one methodological issue which may have arisen if an overt observation was conducted. [2] Effective evaluation includes key terms and is clearly linked to the research. An overt observation may have made the children aware that they were being watched. ‘Demand characteristics’ could be raised as a methodological issue. A link to the study by Bandura et al. would show you have considered the method in context of this specific study. You could do this by mentioning how children may pay more attention to the aggressive model or that children will be restrained in their aggressive behaviour if they know they are being watched. Results » Children in the aggressive model condition showed significantly more imitation of physical and verbal aggression than children who saw the non-aggressive model or no model condition. » Children in the non-aggressive model condition showed very little aggression. » There was evidence of a same-sex effect for boys but not for girls. Boys imitated the male model more than the female model. » Male models had a greater influence on behaviour than female models in both boys and girls. » Boys imitated more physical aggression than girls. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 33 33 14/08/23 7:19 PM Conclusions » Observing aggressive models can lead to imitative aggression in another setting and in the absence of the model. » Aggressive behaviour of male models is more likely to be imitated than aggressive behaviour of female models. Evaluation ▼ Table 3.1 Strengths and weaknesses of Bandura et al. Strengths Weaknesses Reliability – two independent observers recorded the children’s behaviour. Their scores were highly correlated, showing high inter-observer reliability. Generalisation – children were from the nursery of a prestigious university, so the sample may not be representative of children from lower socioeconomic backgrounds. Validity – participants were matched on prior aggression levels. Individual differences in prior aggression levels should not have caused differences in aggression shown within the study, increasing validity. Validity – only two stooges were used, so the children may have imitated the model due to some individual feature that was unique to the model, rather than their sex. Issues and debates Use of children in psychological research » Children are more vulnerable to demand characteristics. » Children may believe the adults expect them to copy the aggression of the adult. Application to everyday life » The study suggests children should be exposed to friendly and prosocial role models so the findings can be applied to parenting and education of children. » TV networks should censor content or provide warnings to prevent children from viewing aggressive content in programmes. SKILLS BUILDER Outline two issues of using children in psychological research using evidence from Bandura et al. [4] When answering this question you should identify two relevant issues such as ‘increased likelihood of demand characteristics’ and ‘the need for parental consent’. You will need to write two detailed sentences for each of your issues. Try using some of the wording from the question to show that you are fully focused, e.g. “One issue of using children in psychological research is that...” This is sometimes called ‘signposting’ as it helps the reader to understand how your response answers the question. Your second sentence could start with another signpost such as “In Bandura et al.’s study....” 3.2 Fagen et al. (elephant learning) Psychology being investigated Operant conditioning Behaviours are reinforced (become more likely) when they are rewarded. Behaviours that are punished become less likely. There are five types of reinforcement (see Table 3.2). These can be used to modify an animal’s behaviour through two processes: 34 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 34 14/08/23 7:19 PM 3 The Learning approach » Shaping: behaviour is gradually modified through a series of stages until the animal is able to consistently reproduce the desired behaviour. Rewards are given for behaviours that are increasingly similar to the desired behaviour. » Behavioural chaining: animals are trained to perform a sequence (chain) of behaviours using reinforcement. Each behaviour in the chain is learned through shaping. Next, the animal is only rewarded when the first two behaviours are performed consecutively. Then a third behaviour will be added, withdrawing and presenting rewards until the full chain has been learned. STUDY TIP Have a look online for videos of ‘clicker training’ which is used to teach tricks to pets and other animals. Compare clicker training with the techniques used by Fagen et al. This should help you to process what you are revising in a different way and hopefully retain what you have learned. ▼ Table 3.2 Types of reinforcement Type of reinforcement Description Example: teaching an elephant to raise its trunk Positive reinforcement Target behaviour is followed by something desirable (a reinforcer/reward); behaviour becomes more likely Elephant is given chopped banana for raising its trunk Negative reinforcement Removal of an aversive/negative stimulus as a reward following a target behaviour; behaviour becomes more likely Elephant is prodded with a stick until it raises its trunk Punishment Undesirable behaviours are followed by an unpleasant/aversive stimulus; behaviour becomes less likely Prodding elephant with a stick when it puts its trunk in any position other than raised Primary reinforcement Using a reinforcer that meets a biological need Giving chopped banana after elephant raises its trunk Secondary reinforcement A whistle is blown as a reward for raising trunk (after the elephants had been classically conditioned to associate the whistle with banana) Using a reinforcer that does not meet a biological need but is associated with a primary reinforcer Background » Traditional elephant trainers (mahouts) use operant conditioning techniques to train working elephants using punishment and negative reinforcement. » These methods raise concerns about animal welfare and keeper safety, so this study used rewards (rather than punishments) to teach the elephants. » The target behaviour was a ‘trunk wash’ (a chain of behaviours necessary to test the elephants for tuberculosis). » Secondary reinforcement training was used to shape the necessary behaviours and then chain them together. First, a whistle (secondary reinforcer) was associated with the primary reinforcer (chopped bananas). The trainers then rewarded the elephants directly after each desired behaviour, using the whistle. Aim To investigate whether secondary positive reinforcement could be used to train elephants to voluntarily complete a trunk wash. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 35 35 14/08/23 7:19 PM Methodology Research method: structured, non-participant observation. (Revise strengths and weaknesses of the different types of observation on pages 67–8.) Data collection techniques: A behavioural checklist (page 67) was used to measure how successful the elephants were in completing trunk-wash behaviours, which included: 1 Trunk here: put trunk into trainer’s hand (for insertion of saline/sterile water using syringe). 2 Trunk up: lift up trunk and hold (to let fluid flow to trunk base). 3 Trunk down: lower trunk into bucket. 4 Blow into the bucket: to collect fluid. 5 Hold steady: keep trunk still. Variables: An assistant observed each training session and recorded: » minutes of training » number of verbal cues made to the elephant » success rate for each behaviour and sequence (after session ten, they were tested every fifth session on everything they had learned so far); success criteria 80 per cent (correct behaviour shown eight out of ten times). Sample: Size: 5. Demographic: elephants housed at the same stable in Nepal; four aged 5–7 years (juvenile), born at the stable; one adult in her 50s; all female. Sampling technique: the elephants were chosen as they were docile (easy to handle) and not pregnant; also their handlers were available and willing. Overview of procedure Training the elephants The five-step trunk wash (see above) was taught using secondary positive reinforcement, shaping and behavioural chaining (see above). Training sessions lasted 2.5-3 hours. Other techniques included: » capturing: banana given following naturally occurring desired behaviours » luring: positioning banana to encourage desired behaviours » verbal cues: one-syllable verbal cues to prompt the elephants to show the five trunk-wash behaviours » desensitisation: the trainers gradually brought the syringe (an aversive stimulus) closer to the elephant’s trunk; the elephant was given banana each time she allowed the syringe nearer » counter conditioning: conditioning the elephant to associate the syringe with banana. Controls » The observer used the same behavioural checklist in each session, including detailed operational descriptions. » The training procedure was standardised. For example, the same verbal cues were used and all training took place in the stalls. NOW TEST YOURSELF 3.4 Describe how the elephants were chosen for the study by Fagen et al. [3] 3.5 Suggest one weakness of the observational method giving an example from this study. [2] 3.6 Give one reason why this study may be said to be high in validity. [2] Ethical issues » Elephants, although chained, were free to walk away if they did not want to participate. » This reduced distress/psychological harm for the animals and risk of physical harm to the trainers if the elephant became uncooperative. 36 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 36 14/08/23 7:19 PM 3 The Learning approach SKILLS BUILDER Describe how quantitative data was collected in this study. [2] Quantitative data is numerical so you will need to think about one or more ways the researcher gathered numerical data from the observation of the elephants. For example, you could mention that the researcher recorded the duration of each session in minutes. You may also describe that the researcher recorded whether the elephants passed or failed each of the trunk-wash behaviours and whether they could do the sequence in order or not. You could elaborate by saying that to ‘pass’ they had to get the behaviour correct on eight out of ten efforts. Results » The juveniles learned the full trunk wash in 25–35 sessions, averaging 12 minutes per session (total training time: 367 minutes). » The adult failed to learn the full sequence. – She did not meet success criteria for blowing and hold steady. – She was also never fully desensitised to the syringe. » Two juveniles also failed hold steady, except as part of the full trunk wash. » The success rate for accurate individual behaviours/sequences increased from 39 to 89 per cent after 35 sessions. » The most difficult behaviour to learn was trunk here/trunk in hand (295 offers). » The easiest behaviour to learn was blow into bucket (54 offers). SKILLS BUILDER Explain how one finding from the study by Fagen et al. supports one assumption of the Learning approach. [2] Think about some specific findings from Fagen et al. and then think about which finding best matches one of the assumptions of the Learning approach. You might know that it was easier to train the elephants to blow into the bucket than to put their trunk in the trainer’s hand, but it is difficult to link this to an assumption. You may consider that performance improved from 39 to 89 per cent over 35 sessions. You could link this to the assumption that we all start as a blank slate and that experience shapes and changes our behaviour. Combine your knowledge from the study, such as how the mahouts responded to the elephants in the training sessions (experience) and how the elephants’ behaviours slowly changed from the early to the later sessions. You could use phrases such as ‘This clearly shows that experience can shape and change behaviour … ‘ before making links back to the study. Conclusions Secondary positive reinforcement is effective for training juvenile elephants to voluntarily and reliably participate in a trunk wash. Evaluation ▼ Table 3.3 Strengths and weaknesses of Fagen et al. Strengths Weaknesses Reliability – the clear operational definitions of trunk-wash behaviours increased the reliability of the observer’s decisions about whether the elephants passed or failed. Subjectivity – only one observer made the decisions about whether elephants passed or failed. They may have been biased as they might have wanted the elephants to be successful. Validity – the mahouts did not speak or signal to the elephants, meaning that behavioural changes were due to the secondary positive reinforcement and not additional communication. Generalisations – the older female elephant in the study may have had poor vision and physical problems. Her poor performance on the trunk wash may not generalise to other older females. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 37 37 14/08/23 7:19 PM Issues and debates Individual and situational explanations » The adult was the only elephant not able to learn the full trunk wash. Individual differences in age/physical health may explain her lack of learning. » Situational factors may have affected her ability to learn the trunk wash. For example: – The trainers may have responded differently to her due to her age. – A young calf kept wandering into her stall. This may have distracted her. Application to everyday life » Fagen et al. developed a safe, ethical and effective way of training elephants to perform health checks. » This procedure will help improve animal health and benefit humans, who can catch tuberculosis from infected elephants. » Animals could be trained for other veterinary procedures using these principles, e.g. taking blood samples or X-rays, decreasing stress and improving wellbeing. The use of animals in research » The small sample follows advice to reduce sample size and use the minimum number of animals required. » Distress/pain was reduced by only using positive reinforcement (not aversive stimuli). The elephants were able to move away if they wished. SKILLS BUILDER Jemima is discussing animal research with her friend. Jemima suggests that animal research can benefit both the animals and society. through reducing accidents and risk of infection. It is preferable to give the reason first and store up the example for the second sentence. Suggest one reason why Jemima may be correct in her assumption that animal research can benefit animals and society. Use an example from this study in your answer. [2] Remember, you need to focus on society (meaning humans, not just animals). You might say that Fagen et al’s procedures can be used to safely test elephants for tuberculosis, meaning infected elephants can be removed from public areas. Show that you understand that this reduces transmission to humans. This question is asking you to think of a reason that Jemima might be right – that animal research can benefit animals and society. Questions like this assess your knowledge of the psychology you have learned, so before you start writing, think about how Fagen et al.’s findings benefit society and not just the animals. You could state that animal research can improve the health and wellbeing of people in society Alternatively, you could explain that Fagen et al.’s research has shown that elephants can be trained with rewards rather than punishments. This should reduce accidents resulting from elephants becoming aggressive when punished. 3.3 Saavedra and Silverman (button phobia) Psychology being investigated The study investigates how learning theories can be used to explain the acquisition and treatment of phobias. » Classical conditioning: a previously neutral stimulus triggers the same emotional or bodily reaction as an unconditioned stimulus with which it has been previously paired. 38 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 38 14/08/23 7:19 PM 3 The Learning approach – Example: Watson and Rayner (1920) showed a baby a white rat (neutral stimulus) before loudly hitting a metal bar (unconditioned stimulus). After several repetitions, the baby became distressed (a conditioned response) whenever he saw the rat (now a conditioned stimulus). – This is called expectancy learning. The baby expects a negative and potentially threatening event (the loud bang) whenever he sees the rat. » Evaluative learning: a strong emotional response to a previously neutral stimulus acquired via classical conditioning. – There is no expectation of a certain type of event (positive or negative). However, the object/situation is now associated with strong feelings (e.g. disgust). – Example: a woman picks a flower (neutral stimulus) and is disgusted (unconditioned response) when a slimy worm (unconditioned stimulus) touches her hand. She now feels sick (a conditioned response) at the sight of similar flowers (conditioned stimulus). » Operant conditioning: behaviours that are followed by positive reinforcement (reward) become more common. Behaviours followed by punishments become less common. – Example: praising a person with a dog phobia for stroking a dog, to help the person to learn that dogs are typically friendly and harmless. SKILLS BUILDER Outline an example of either classical or operant conditioning using an example from the study by Saavedra and Silverman. [2] This question includes the command term ‘outline’. You will need a brief description of one type of conditioning only. Choose the one with which you feel most confident. An example of operant conditioning: the boy acquired his button phobia via evaluative learning, a type of classical conditioning. His treatment included praise (positive reinforcement) for touching buttons (the desired/target behaviour) from his mother. Either (but not both) could be used in this answer. STUDY TIP Interleaving is an evidence-based revision strategy. At first sight, it may seem rather counter-intuitive. Instead of learning a whole block of material at one time (e.g. everything there is to know about the Saavedra and Silverman study), it involves practising several different types of new material in succession and periodically revisiting them. For example, revising the aims of each of the core studies for the Learning approach, then the methodology of each study, then the results and so on. As you do so, you should draw comparisons between the studies. Mixing things up in this way has been shown to improve longterm retention. It may not work for everyone, but it’s worth a try. Background Diagnosis » Phobias are diagnosed by psychiatrists and clinical psychologists using manuals such as the DSM-5 (American Psychiatric Association, 2013). » Semi-structured interviews are often used to diagnose patients, including assessing the severity and duration of symptoms. Previous research » Targeting disgust can help treat adults with blood-injury phobias. » As fear decreases, so does disgust in spider-phobic children. Aims 1 To identify the cause of the boy’s phobia. 2 To test cognitive-behavioural therapy, including imagery exposure, as a treatment for a disgust-based phobia of buttons. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 39 39 14/08/23 7:19 PM SKILLS BUILDER Saavedra and Silverman was a case study. Explain one limitation of a case study as a research method in this study. You must not refer to generalisability in your answer. [2] People often refer to all psychological studies as case studies, but this is wrong. You can refresh your knowledge of the key features of this research method on page 66. This question focuses on limitations or disadvantages of case studies. A possible limitation is that findings should be generalised with caution as they focus on one individual or small group only and they may not be representative of other people in the target population. However, the question states that you must not use generalisability in your answer. This shows that you need to know at least two advantages and disadvantages of each research method. Once you have selected a suitable limitation (e.g. subjectivity due to the rapport that may develop, longitudinally, between the researcher(s) and the participant), your second sentence needs to focus on why this is a limitation. Your point and your reason should be linked to specific details of Saavedra and Silverman’s methodology as the question includes the key phrase ‘in this study’. Methodology Research method and design: case study with a longitudinal design; data was gathered before, during and after therapy and at 6- and 12-month follow-ups. 8 Data collection techniques: 7 Quantitative data: 6 » A psychometric rating scale called a feelings thermometer was used to measure subjective distress from 0–8. » The number of buttons touched, held or manipulated was counted in each session. 5 Qualitative data: » There was a semi-structured interview and observation of therapy sessions. Notes were made about approach/avoidance of buttons. (Revise different interviewing techniques and formats on pages 64–65, and different types of observation on page 67.) 4 3 2 1 0 Sample: Size: 1. Demographic: A Hispanic-American boy (age nine) was refered to a clinic in Florida, USA due to a phobia of buttons. He had no other disorders (e.g. OCD). Sampling technique: opportunity sample – chosen by the researchers due to his unusual phobia. ▲ Figure 3.1 A feelings thermometer was used to provide quantitative data to assess changes in the boy’s level of distress before, during and after therapy Overview of procedure Assessment of phobia » The Anxiety Disorders Interview Schedule for DSM-IV–Child and Parent (ADIS-C/P) was used to confirm the boy’s phobia diagnosis using a semi-structured interview. » A ‘feelings thermometer’, a nine-point scale (from 0–8), was used to assess symptom severity. » Possible triggers of the phobia were explored (e.g. trauma) to inform treatment. Treatment of phobia » Four 50-minute exposure sessions (20 minutes with mother): – Boy ranked 11 button-related stimuli from least to most distressing using a feelings thermometer (0–8 point scale) (see Figure 3.1). 40 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 40 14/08/23 7:19 PM 3 The Learning approach – The ranked list was used to create a disgust/fear hierarchy. – The boy was gradually exposed to each stimulus. – The boy was positively reinforced for tolerating/touching the buttons (e.g. praised by his mother). » The therapist conducted seven disgust-related imagery exposure sessions: – The boy imagined and described the look, smell and feel of buttons. – The therapist used cognitive restructuring. » The ADIS-C/P was used to measure symptoms after the treatment sessions had finished and at six and twelve months after treatment. Ethical issues » Informed consent was obtained from mother and child, helping to protect both from psychological harm. » Personal details relating to the acquisition of the phobia may have compromised the boy’s anonymity. This increases his risk of psychological harm. Results Cause of phobia Button avoidance began following a distressing event when the boy was five years old: » He tipped a bowl of buttons onto himself at kindergarten. » This happened in front of the class and the bowl was on the teacher’s desk. Difficulties experienced following this event: » He was unable to touch/handle buttons, including dressing/undressing. » He had poor concentration at school due to buttons on his uniform. » He avoided clothes with buttons and people with buttons on their clothing. Exposure therapy progress (sessions 1–4) Positive outcomes: » The boy worked through all the situations on the disgust hierarchy. » He handled more buttons in each exposure session. Negative outcomes: » Feelings thermometer distress ratings increased. » Some of the situations from the disgust hierarchy received higher ratings after the first four sessions than before. Disgust-related imagery and cognitions (sessions 5–11) » The boy said buttons are ‘disgusting’ and ‘gross’. He could not say why, except that buttons smell unpleasant. » Distress ratings on the feelings thermometer decreased: – Hundreds of buttons falling all over his body went down from 8 to 5 to 3. – Hugging his mother with a ‘shirt full of buttons’ went down from 7 to 4 to 3. Follow-up sessions at 6 and 12 months (after therapy ended) Phobia criteria were not met when assessed using the ADIS-C/P: » Buttons no longer triggered distress. » School uniform with small clear plastic buttons was worn daily without issue. Conclusions Childhood disgust-based phobias: » can be explained using evaluative learning » may require imagery exposure and cognitive restructuring as well as exposure therapy. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 41 41 14/08/23 7:19 PM Evaluation ▼ Table 3.4 Strengths and weaknesses of Saavedra and Silverman Strengths Weaknesses Validity – triangulation of qualitative and quantitative data-gathering techniques increases credibility (e.g. semi-structured interview, observations of therapy sessions, use of feelings thermometer). Reliability – therapy sessions were patient focused and therefore cannot be replicated exactly. Reliability of findings cannot be checked. Validity – follow-up sessions at 6 and 12 months meant long-term efficacy of treatment could be assessed. Subjectivity – self-reported data may be biased. For example, the mother sees child’s behaviour differently from child, and vice versa. Both may be overly positive about the long-term benefits of the therapy due to their relationship with the therapist. Issues and debates Application to everyday life » Disgust-based phobia therapists should be trained in the use of imagery exposure and cognitive restructuring. » These techniques may help treatment-resistant clients who have not shown improvement with traditional exposure theory. Nature versus nurture » Nurture is supported as learning experiences in therapy helped change the boy’s behavioural and emotional responses. » Phobias may be influenced by nature and nurture: – The disgust response helps us to avoid germ-ridden stimuli and therefore has survival value. It is part of our evolutionary inheritance. – Evaluative learning also has survival value as we learn to avoid stimuli that are associated with disgust. Use of children in psychological research » The diagnostic interview schedule used in the study had been adapted for use with children to improve validity. » A ‘feelings thermometer’ was created to help the boy to express changes in his feelings of distress/disgust. SKILLS BUILDER The study by Saavedra and Silverman has been used to inform the treatment of people with disgust-based phobias. Outline one alternative way that the findings from this study could be applied in everyday life. [2] When you are revising the 12 core studies, try to prepare two applications to everyday life for each as you may be faced with a question like this. The opportunity to outline the most obvious application is ruled out in this question and instead you must come up with another suitable response. Thinking about the aim of the study should help you. Saavedra and Silverman were not only interested in treatment of phobias but also in their development. How could an understanding of the way in which the disgust response is learned be useful in everyday life? For example, could we possibly create a disgust response to deter someone from something they once liked but is bad for their health? 42 NOW TEST YOURSELF 3.7 Saavedra and Silverman treated a boy with a phobia of buttons. Explain two ways in which the boy’s subjective ratings of distress changed throughout his therapy. [4] 3.8 Give one strength of the use of semistructured interviewing in this study.

(Cambridge International, 2021) 4.1 Milgram (obedience) Psychology being investigated » Obedience is the result of social pressure where one person complies with a direct order of an authority figure. » According to Milgram, people have a strong tendency to be obedient and a system of obedience is needed for people living in a community. » Milgram proposed a variety of explanations for why people obey others. Background » Obedience is important for social life but can be destructive. » According to Milgram, the slaughter of millions of people from 1933 to 1945 ‘could only be carried out on a massive scale if a very large number of persons obeyed orders’. » He believed extreme obedience to authority was a one-off, that ‘the Germans were different’. He expected that in the 1960s in the USA, no one would obey if he created an extreme situation. » Before the study, Milgram asked 14 Yale University senior students, ‘Would you give an electric shock to another person?’ Less than 3 per cent said they would. His colleagues believed that few, if any, would give shocks. » Milgram wanted to test the ‘Germans are different’ hypothesis, which explains obedience in terms of dispositional factors, such as personal conscience. STUDY TIP Revision notes can be transformed in creative ways to suit your information processing style. Try writing a newspaper article to the people who live in New Haven (in 1960) about the research conducted by Milgram. Aim To investigate the level of obedience when the authority figure’s command requires destructive behaviour. SKILLS BUILDER Explain one feature of Milgram’s procedure which increased the realism of the situation. [2] For these types of questions where you are explaining features, use psychological terms in your answers. You first need to identify features of the study that increased the realism, such as the sample shock given, drawing slips to decide who 44 was the teacher/learner or meeting Mr Wallace (the confederate) before the experiment. You can explain the feature fully so do not forget your key terms. What does realism mean? You can refer to either the mundane realism of the task or the ecological validity of the setting – either way, you are showing you understand the process of psychological research.

The observer recorded the participant’s level of obedience (the maximum voltage of shock delivered) and signs of anxiety. » Interview: after the study, an unstructured interview was carried out using openended questions about how the participants felt about obeying authority. Variables: Measured variable: Maximum voltage of shock administered before refusing to go any further. There were 30 switches (ranging from 0 to 450 volts). Participants were classed as ‘defiant’ if they stopped before 450 volts. Sample: Size: 40 men. Demographic: All aged 20–50 years; from New Haven, United States of America; from a variety of manual and professional occupations. Sampling technique: self-selected via newspaper and direct mail advertisements. Volunteers were paid $4.50. Overview of procedure » The study was conducted at Yale University. » Participants were told that the study was about the effect of punishment on learning. » Naive (real) participants were introduced to another participant, ‘Mr Wallace’ by the experimenter who were both confederates of the study. » A rigged lottery was used to decide who would be ‘teacher’ and ‘learner’. The real participant was always the teacher. » The teacher and learner were taken to an adjoining room. The learner was strapped to a chair and electrodes were attached to their wrists. » The teacher was taken to an adjoining room and seated in front of a shock machine. The teacher received a sample shock of 45 V. » The experimenter remained in the same room as the teacher throughout the test. » The learning task involved the learner memorising word pairs. Participants read word-pairs to the learner and then read the first word of a word pair with four options. » The experimenter instructed the teacher to administer a shock when the learner gave an incorrect answer. They were told to increase the voltage each time (by 15 V). » Four standardised prods were used if the teacher resisted: 1 Please continue. 2 The experiment requires that you continue. 3 It’s absolutely essential that you continue. 4 You have no other choice; you must go on. » A thorough debrief was given at the end of the study, and the teacher and learner were reunited and interviewed about the experience. SKILLS BUILDER In Milgram’s study, there were two confederates playing different roles. Outline the roles of the confederates in this study. [4] When outlining the roles of the confederates, you need to provide some detail of who they were (in relation to the participant), what they did and as confederates how they contributed to the deception. Controls » All participants drew lots, the same prods were given and the same word pair task was used. » All participants heard the learner supposedly pounding on the wall in protest at 300 volts and 315 volts. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 45 45 14/08/23 7:19 PM Ethical issues » Participants were deceived when they were told the aim of the research was learning and memory. » Milgram thoroughly debriefed his participants, revealing that the experimenter and learner were confederates. The learner reassured the participant that he was completely unharmed. » Participants were further deceived into believing that the learner (confederate) was another participant and that the electric shocks were real. » The prods used by the experimenter prevented participants from leaving the study. » Three participants had seizures and the majority showed signs of intense distress. NOW TEST YOURSELF 4.1 Explain why Milgram ensured the participant met the learner at the end of the study. [2] 4.2 A fake shock generator was used to measure obedience in this study. Describe how Milgram collected quantitative data using this apparatus. [2] 4.3Outline two prods used by the experimenter if the participants expressed an unwillingness to continue. [2] Results Quantitative results » 26 out of 40 participants administered the maximum 450 V (65%). » 40 out of 40 went up to 300 V (100%). Qualitative results » Extreme tension was observed (sweating, trembling, biting lip, etc.). » Fourteen participants showed signs of nervous laughter and smiling. » Three participants had seizures. Conclusions » Participants were willing to oppose their moral values to obey an authority figure, even when it meant harming another person. » Following destructive orders caused emotional strain on the participants. Evaluation ▼ Table 4.1 Strengths and weaknesses of Milgram Strengths Weaknesses Reliability – controls of the procedure (same instructions Generalisation – the study had low population validity by the experimenter, feedback from the learner) led to as it included only Americans. Obedience may be higher level of standardisation. different in other countries. Validity – participants were unaware their reactions were being recorded and a false study aim was given, decreasing the chance of demand characteristics. Validity – shocking a stranger is not an everyday task so does not reflect obedience to situations in real life. Issues and debates Individual and situational explanations » Only 65 per cent obeyed to the maximum voltage, supporting an individual explanation of obedience; 35 per cent were defiant and resisted the 46 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 46 14/08/23 7:19 PM 4 The Social approach experimenter’s prods to continue causing harm. This suggests personal factors were responsible for their resistance. » Situational factors, such as the location of the experiment (Yale University), resulted in all 40 participants giving 300 V. Application to everyday life The findings can be used to educate people to resist authority in cases of destructive obedience. Training programmes have been developed for soldiers in some armies to highlight the importance of resisting orders on moral grounds. SKILLS BUILDER Darcie believes Milgram’s study supports the individual side of the debate, but Freja believes it supports the situational side of the debate. Outline why you think either Darcie or Freja is correct, using evidence from the study. [4] Your skills of supporting claims is being tested here so you need to write effectively (not excessively). A side does need to be taken and supported clearly. You could use the PEEL method to put forward your answer with questions like this: » Point: Darcie is correct in believing Milgram’s study supports the individual side of the debate. » Evidence: Thirty-five per cent of participants refused to obey the commands given by the experimenter and stopped before 450 V. » Explain: By refusing to obey to the end, defiance was shown in participants, suggesting personal factors, such as empathy, were responsible for their behaviour. » Link: Therefore, Darcie’s claim, that the individual’s characteristics are important in determining behaviour when exposed to destructive obedience, is supported in Milgram’s research. 4.2 Perry et al. (personal space) Psychology being investigated Interpersonal distance » Interpersonal distance is the distance between people, such as how close they sit or stand to each other. » It often shows how comfortable people feel with one another. Personal space » Personal space is the invisible boundaries around our bodies that, if crossed, make us feel uncomfortable or threatened. » Preferred distance from others depends on: – cultural values – individual differences – the relationship with the other person: intimate or social – the situation: formal or public. Empathy » Empathy is a person’s ability to understand the thoughts, feelings and experiences of others. » Empathy has two dimensions: – cognitive: the ability to determine another’s emotional/mental state – affective: the ability to ‘feel’ the same emotional state. STUDY TIP You may be asked to compare studies in terms of their similarities and differences. As you review Perry et al., consider other social studies, such as Milgram. One technique to increase understanding is to create Venn diagrams that clearly outline similarities and differences between studies. Social hormones » Social bonding can be affected by hormones such as oxytocin. » Psychologists are interested in how oxytocin affects an individual’s interpersonal distance preference (how close they are willing to be to another person), depending on whether they are high or low in empathy. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 47 47 14/08/23 7:19 PM Background Amygdala » The amygdala is a brain structure that is involved in processing emotions. » The amygdala triggers strong emotional reactions following personal space violations, so regulating interpersonal distance in humans. » Oxytocin regulates amygdala activity. » Lesions to the amygdala reduce the need for interpersonal distance. Social salience hypothesis » Oxytocin increases attention to social cues. » Attentiveness affects how cues are processed and our responses. » Processing and responses are also affected by social setting (e.g. presence of a physically attractive stranger). » This explains why some people feel threatened while others feel comfortable in the same social situation. Perry et al. predicted that preferred interpersonal distance following oxytocin administration may differ depending on whether the person is high or low in empathy. People with high empathy would prefer closer distance and those with low empathy would prefer greater distance. Aim To investigate the effect of oxytocin on preferred interpersonal distance for those scoring high or low in empathy traits. Methodology Research methods and design: two laboratory experiments; half of the participants did Experiment 1 first and the other half did Experiment 2 first. Both experiments used mixed designs: » Repeated measures design with randomisation – participants took part in two conditions, with and without oxytocin, one week apart. (Revise the difference between randomisation, random allocation and random sampling on pages 59–60.) » Independent measures design – whether participants were in the high or low empathy group (see ‘variables’). Data collection techniques: » Questionnaire: the Interpersonal Reactivity Index was used to create the high and low empathy (interpersonal reactivity) group scores. Participants with scores of over 40 were assigned to the high empathy group (n = 20) and those with scores of under 33 were assigned to the low empathy group (n = 20). » Standardised tests: – Experiment 1: the Comfortable Interpersonal Distance (CID) paradigm. – Experiment 2: the ‘choosing rooms’ task. Variables: Independent variable 1: empathy (low or high). Independent variable 2: oxytocin or placebo/saline solution. Sample: Size: 54 men. Demographic: Undergraduates from an Israeli University, aged 19-32 years; five were left-handed; all had normal vision and were mentally well (confirmed by a screening interview). 48 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 48 14/08/23 7:19 PM 4 The Social approach Sampling technique: volunteer (self-selecting), participating for exchange of course credit or payment provided. Overview of procedure » An online questionnaire was completed for empathy score. » Three drops of nasal solution (oxytocin or saline) were self-administered in the presence of experimenters. » Participants waited 45 minutes (in a comfortable, quiet room) before further testing. Nature magazines were given to reduce social interaction. Experiment 1: CID Independent variable 3: condition (stranger, authority, friend or ball). Repeated measures. Dependent variable: preferred interpersonal distance was measured using the CID paradigm. Participants indicated when they wanted the person/object to stop. A percentage score was given of the remaining distance from the total distance: 0 = figures touching; 100 = furthest distance. » Participants sat at a computer while three-second animations were displayed showing a figure approaching the centre of a circle. » Participants were shown the name of the approaching figure (stranger, friend, authority or ball) for one second, followed by a fixation point for 0.5 seconds. » Participants saw a still picture of a circular room with a figure at the centre and an approaching figure at one of the eight entrances. » Participants imagined themselves at the centre of the room and pressed the spacebar on the computer keyboard to show when they wanted the figure (protagonist) to stop » Each of the four figures appeared three times from each of the eight entrances, resulting in 96 trials in total. Experiment 2: Changing rooms (Figure 4.1) Independent variable 3: condition – positioning of chairs (experimental) versus positioning of table and plant (control). Dependent variables: 1 Mean average preferred distance between the two chairs (cm) 2 Mean average preferred angle of the two chairs (degrees). All participants gave preferences for both the chairs and the table and plant. (repeated measures) » Participants were informed the task was to aid planning a room layout for conversation with another participant on a personal topic. » They were shown colour pictures of two very similar rooms. Rooms contained identical chairs in the middle, a table and a plant (see Figure 4.1). » 84 pairs of rooms, shown twice. Participants chose the left or right room. Only one independent variable differed on each trial. » Researchers compared the preferences for the spatial arrangement of the chairs (measure of interpersonal distance measurement) and the table and plant (control condition).

Pictures differ in terms of the angle (degrees) and distance between (cm) the chair and the table/plant. NOW TEST YOURSELF 4.4Outline how a repeated measures design was used in this study. 4.5 Explain the use of a placebo group in this study. 4.6Outline the procedure of the ‘choosing rooms’ task. [2] [3] [2] Controls » Neither the participant nor the researcher conducting the standardised tests knew whether saline or oxytocin had been administered (double blind design). (Revise researcher effects, single and double blind designs on pages 60 and 61.). » The order of the experiments was counterbalanced. » All participants waited 45 minutes before starting the experiment after administering a solution (oxytocin or saline). » The same three-second animation was used for all participants. » Fixation points were used to ensure attention. (Revise researcher effects, single and double blind designs on page 61.) Ethical issues » Informed consent was gained before participants administered the nasal solution. » A debrief was given of the full purpose of the study at the end of the second experiment. 50 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 50 14/08/23 7:19 PM 4 The Social approach Results Experiment 1 » Oxytocin decreased the preferred mean distance from a protagonist in the high empathy group and increased it in the low empathy group. » Significant differences were found for the preferred distance between a friend and an authority figure, and a friend and a stranger in the high empathy placebo group. » Participants were willing to be closer to the ball than the stranger or authority figure in the oxytocin condition. Experiment 2 » The high empathy group chose closer chair distances in the oxytocin condition compared to the placebo. The opposite effect was found in the low empathy group. » Oxytocin did not significantly affect preferred chair angle. Conclusions Oxytocin affects preferred interpersonal distance dependent on empathy level. High empathy individuals prefer closer distances after oxytocin compared to the placebo. Preferred interpersonal distance increased with the use of oxytocin for individuals with low empathy scores compared to the placebo. SKILLS BUILDER Give one strength of using a double-blind technique in the research by Perry et al. [2] Refer to page 72 and review what is meant by the double blind technique. Make a clear point ‘The technique reduces experimenter bias and demand characteristics’. Give a clear link to Perry et al by referring to how the participants and experimenters were unaware of which solution was administered (saline or oxytocin). You can elaborate by outlining the impact this had e.g. participants could not exaggerate their responses to the oxytocin by acting more sensitively to changes in personal distance. Evaluation ▼ Table 4.2 Strengths and weaknesses of Perry et al. Strengths Weaknesses Validity – the double-blind procedure avoided experimenter effects and demand characteristics. Prior expectations did not influence the effect of oxytocin. Validity – bias may exist in the self-report measure. Participants may have over-reported their empathy to appear more socially desirable. Objectivity – quantitative data allows scores to be compared. The percentage distance remaining was measured without subjective interpretation. Generalisability – All male sample used, the findings may not be true for girls and women with ASD who might still benefit from oxytocin. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 51 51 14/08/23 7:19 PM Issues and debates Application to everyday life » The findings suggest that oxytocin may not be an effective treatment for individuals with social deficit disorders e.g. Autistic Spectrum Disorder. » Participants in the low empathy group preferred increased interpersonal distance when oxytocin was administered, so this may strengthen social biases. Individual and situational explanations » Individual differences (level of empathy) determine the effect oxytocin has on a person’s social behaviour. » Oxytocin administration resulted in predictable outcomes in behaviour. This suggests that situations promoting oxytocin release could influence social behaviour, which supports the situational explanation. 4.3 Piliavin et al.

You can make use of technology by creating a crossword online. Include key concepts, research terms and evaluation issues of Piliavin et al. as a revision aid. SKILLS BUILDER ‘Research into personal space has no relevance in everyday life.’ Explain how Perry et al.’s research provides evidence for and against this claim. [4] First, consider what ‘relevance in everyday life’ means. Relevance is about usefulness, and many factors can affect it. You can refer to the applications in everyday life, but you can also refer to methodological issues which restrict these applications. For instance, you could discuss ecological validity and how the research is based on laboratory studies and computerbased tasks, so not reflecting personal space decisions in everyday life. Psychology being investigated Bystander apathy The presence of other people discourages a person from helping/intervening in an emergency/high danger situation. Therefore, people are more likely to help when they are alone than when they are part of a group. Diffusion of responsibility Responsibility to help is shared between the number of bystanders present; the more bystanders, the less responsible each person feels and the less guilty felt for not helping. Background » Interest in bystander apathy increased following the murder of Kitty Genovese (1964). » A newspaper claimed that none of the 38 witnesses telephoned the police. » Psychologists began to conduct laboratory experiments into ‘bystander behaviour’. » Darley and Latané conducted studies such as ‘a lady in distress’, ‘an epileptic seizure’ and ‘the smoke-filled room experiment’. » The findings showed that, as group size increased, the amount of helping decreased. This was termed diffusion of responsibility. 52 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 52 14/08/23 7:19 PM 4 The Social approach Aim To investigate how the following factors affect helping behaviour in a real-life setting: » type of victim (drunk or ill) » race of the victim (black or white) » modelled help » group size. SKILLS BUILDER Explain what psychologists have learned about bystander behaviour using two results from the Piliavin et al. study. [4] Read the question a second time so you can focus your attention: »Circle the command words. » Underline the subject words. » Box any limiters. Explain what psychologists have learned about bystander behaviour using two results from the Piliavin [4] et al. study. Only when you have understood the question are you ready to answer. This question is focused on results so you should explicitly refer to two separate results and how each findings links to psychological concepts such as bystander apathy and diffusion of responsibility. Take care, the findings of this study contrast with some of the findings in the background research. It appears that bystanders are not always as apathetic as you might think! Methodology Research methods and design: field experiment with independent measures design (participants experienced either an ill/black, an ill/white, a drunk/black or a drunk/ white trial). Data collection techniques: Covert observation (revise different types of observation on pages 67.): » Observer 1 recorded: – sex, race and location of passengers (seated or standing) in the critical area (see Figure 4.2) – total number of people in the car – total number of people who went to help (including race, sex and location). » Observer 2 recorded: – sex, race and location of passengers in the adjacent area – time taken for the first passenger to help (the latency) » Both observers recorded comments by passengers. » Movement of passengers out of the critical area was also recorded. Variables: Independent variables: » type of victim, 65 ill (carried a cane) or 38 drunk (smelt of alcohol, carried a liquor bottle). » race of victim (black or white) » modeled help (from confederate): time (70 or 150 seconds after collapse) and proximity (confederate helper was in the critical or adjacent area) » group size (naturally occurring, e.g. number of passengers in the carriage). Dependent variables: » frequency of helping » speed of helping » race of helper Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433_CH04.indd 53 53 18/08/23 6:49 AM » sex of helper. » movement of passengers in and out of critical and adjacent areas. » Comments made by passengers (qualitative data) Sample: Size: 4,450 unaware passengers. Demographic: men and women; passengers on the New York subway; approximately 45 per cent black and 55 per cent white. Sampling technique: opportunity sample consisting of passengers travelling on the 8th Avenue subway between 11 a.m. and 3 p.m. on weekdays. Overview of procedure » Two male confederates (victim and model) and two female observers boarded the express subway train via separate doors. » The observers took separate seats while the male victim stood in the critical area. The male model varied position (adjacent or critical area). » Seventy seconds after leaving the station, the victim staggered forward and collapsed. He lay still and looked upwards until he was helped. » The model helped the victim to his feet. None of the passengers helped. Controls » The same seven-and-a-half minute train journey was used for all trials. » Victims wore the same clothes (old trousers, jacket and no tie) and fell after 70 seconds in the same place and in the same way. » Each team member started the journey in the same place (e.g. Observer 1 in the adjacent carriage near the exit door and Observer 2 in the adjacent carriage in the far corner). Ethical issues » Informed consent: participants were not informed that an observation was occurring on the subway. » Lack of debrief: passengers moving out of the carriage when the subway stopped meant debriefing was impossible. » Passengers may have left the carriage in a negative psychological state (shocked/ distressed). » Deception: passengers were unaware of the use of confederates. NOW TEST YOURSELF 4.7Outline one difference between the adjacent area-early and adjacent area-late conditions. [2] 4.8Outline what is meant by a covert observation. [2] 4.9Outline one feature of Piliavin et al.’s research that increased the validity of the results. [2] SKILLS BUILDER Two ethical guidelines are informed consent and debriefing. Suggest how ethical issues raised in the Piliavin et al. study relate to these two ethical guidelines. [4] As with the previous Skills Builder, read the question again and actively process it: » Circle the command words. »Underline the subject words. » Box any limiters. You can apply this process to all questions. A command term shows which skill is being assessed. The subject words relate to the topic/aspect the question is about. Limiters refer to specific demands of the question. Two ethical guidelines are informed consent and debriefing. Suggest how ethical issues raised in the Piliavin et al. study relate to these two ethical guidelines. [4] Avoid focusing on one aspect of the question and consider the limiters given. You can define what is meant by informed consent and debriefing but the command is to ‘suggest’. Therefore, you need to say how these are ethical issues within Piliavin et al.’s procedure. 54 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 54 14/08/23 7:19 PM 4 The Social approach Results » Type of victim: a person appearing ill received more help than a person appearing drunk (62/65 of trials versus 19/38 of trials). » Race of victim: there was a tendency for same-race helping in the drunk condition. » Modelled help: early models were more likely to prompt additional help than late models. » Group size: there was a weak positive correlation between group size and helping, but this was not significant. Other findings: » Males helped more than females: 90 per cent of first helpers were male. » People left the critical area in 20 per cent of trials. » Female comments included: ‘It’s for men to help him’, ‘I wish I could help him – I’m not strong enough.’ Conclusions » Observation of an emergency situation creates unpleasant arousal bystanders aim to reduce. » The strength and nature of arousal depends on empathy for the victim, distance from the emergency and length of time without intervention. » People reduce arousal by directly helping, fetching help or leaving the scene. » Individuals compare costs of helping (effort, ability, disgust) with the cost of not helping (self-blame, guilt) and rewards (e.g. reduced arousal, approval from others). » No support was found for diffusion of responsibility – help was offered frequently and quickly. Evaluation ▼ Table 4.3 Strengths and weaknesses of Piliavin et al. Strengths Weaknesses Objectivity – quantitative data allowed comparison of helping behaviours between the drunk and ill conditions. Reliability – the observers recorded different things, so inter-rater reliability could not be checked. Validity – insight into bystanders’ thinking was given with comments recorded. Meaningful conclusions could be drawn about the justifications of not helping. Generalisation – the research lacked population validity as passengers were observed on an urban train route; people in more rural areas may behave differently meaning findings should be generalised with caution. Issues and debates Individual and situational explanations » The situation of an ill victim falling triggered helping behaviour – help was offered without a model intervening on every trial. » Ninety per cent of first helpers were male, suggesting individual characteristics affect rates of helping. The cost–reward matrix suggests appraisal of whether to offer help differs between individuals. Application to everyday life » Responses to emergency situations could be changed through education and training. » Programmes could be developed for young people to understand the cost–reward matrix and their own biases and emotions to emergency situations. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 55 55 14/08/23 7:19 PM SKILLS BUILDER Piliavin et al. concluded that the cost–reward matrix determines whether people help. Outline how this model supports an individual explanation of behaviour.

STUDY TIP Many key terms are reviewed when looking at research methods. Familiarise yourself with them and create your own glossary as part of your independent study. Laboratory experiments » A laboratory setting is maintained where the experimenter has a high level of control (e.g. temperature regulated, lighting controlled and noise managed). » Controls are in place to ensure only the independent variable changes between conditions. ▼ Table 5.1 Evaluating laboratory experiments Strengths Weaknesses Ethics – participants give a degree of consent, but not necessarily informed. The right to withdraw is often given. Validity – artificial conditions (setting and task) can produce unnatural behaviour, lowering ecological validity. Reliability – procedures involve standardised instructions and procedures, giving consistency. Validity – features of the environment may reveal the aim, leading participants to act in a way they feel the researchers want them to (demand characteristics). Validity – a high level of control allows cause and effect to be shown. Ethics – there may be deception of the aim of the study to ensure validity. Links to studies » Pozzulo et al. (line-ups) asked participants to observe video clips in a controlled setting before identifying the target person in different types of line-up. » Dement and Kleitman (sleep and dreams) got participants to sleep in a controlled setting and they were awoken in either REM sleep or NREM sleep. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 57 57 14/08/23 7:19 PM SKILLS BUILDER In Perry et al.’s (personal space) laboratory experiment, the dependent variable of interpersonal distance was measured using CID, with the participants indicating when they wanted the person/ object to stop. A percentage score was given of the remaining distance from the total distance (0 = figures touching, 100 = furthest distance). Describe one other way this dependent variable can be measured, using any examples. [3] Suggested answer structure (What, How, Elaborate): Participants could be measured on their preferred personal distance using a questionnaire (What). They could be asked, ‘What distance would you stand away from a stranger?’ (How). This could be a closed question, with choices such as ‘less than 18 inches’, ‘18 inches to 4 feet’, ‘4 feet to 12 feet’ (Elaborate). You need to do more than just identify another way of measuring interpersonal distance. Give detail of how it will be measured. Field experiments » Field experiments take place in natural settings (e.g. streets, workplaces). » Natural environments may involve uncontrolled variables both within and between groups/conditions. » Controls are difficult to implement in a natural setting (e.g. public places). Uncontrolled, situational variables make it hard to draw firm conclusions. ▼ Table 5.2 Evaluating field experiments Strengths Weaknesses Validity – participants do not know they are taking part, so they are less likely to show demand characteristics. Ethics – participants often do not know they are taking part so this removes their right to withdraw and means debriefing is often impossible. Validity – there is high ecological validity as participants are in their everyday environment. Reliability – there is less control over extraneous variables, making research difficult to replicate. Link to study Piliavin et al. (subway Samaritans) carried out a field experiment on an express train between two New York stations and the researchers manipulated the type of victim and whether help was offered by a confederate or not. SKILLS BUILDER Anya wants to plan a study using a field experiment to investigate the effect of the presence of others on shopping habits. Describe how Anya could conduct this study. [10] Key features of experiments you could include in your answer: »Review how the independent variable (presence of others) will be changed. » Detail how the dependent variable (shopping habits) will be measured (fully operationalise). »Outline procedures to collect data (step-by-step in the natural location). Highlight it as a field experiment, so describe the natural environment that the test will be conducted in (shopping centre). 58 NOW TEST YOURSELF 5.1Outline two features of the laboratory experiment used by Andrade (doodling).

[2] Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 58 14/08/23 7:19 PM 5 Research methodology 5.1.2 Experimental designs An experimental design is how participants are allocated to groups/conditions of the independent variable. There are three types of design: repeated measures, independent measures and matched pairs. Independent measures Each participant takes part in one group/condition of the independent variable. ▼ Table 5.3 Evaluating independent measures designs Strengths Weaknesses Validity: There are no order effects as participants take part in only one condition e.g. fatigue, boredom, or practice effects. Validity: More participants are needed to gather data. Validity: Less chances of demand characteristics: participants are less likely to guess the aim. Validity: There is no control for participant variables. For example, participants in one group may be naturally better at the task given. One way to eliminate participant variables is to randomly allocate participants to conditions. Random allocation is done by tossing a coin or allowing a computer to allocate groups. Links to studies » Andrade (doodling) randomly allocated participants to either the doodle or the non-doodle condition. » Piliavin et al. (subway Samaritans) tested participants with either an ill or a drunk victim. Repeated measures Each participant takes part in all conditions of the independent variable. ▼ Table 5.4 Evaluating repeated measures designs Strengths Weaknesses Validity: Participant variables are controlled as the same people do both conditions. Validity: Order effects can occur. Chances of demand characteristics are increased. Fewer participants are needed, which is useful if samples are limited. Apparatus may need duplicating – for example, for two variations of a test. One way to eliminate order effects is to counterbalance conditions. Each condition is tested first in equal amounts. So half the participants first experience condition A and then condition B, while the other half of participants first experience condition B and then condition A. STUDY TIP Include examples of studies using different experimental designs in your revision notes. How are they identified as that design? For example, Hassett et al. used an independent measures design to compare male rhesus monkeys with female rhesus monkeys. Pozzulo et al. used an independent measures design to compare young children to adults. Links to studies » Dement and Kleitman (sleep and dreams) compared recall of dreams from REM and NREM sleep with each participant. » Perry et al. (personal space) tested all participants with and without oxytocin. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 59 59 14/08/23 7:19 PM SKILLS BUILDER Xiu is carrying out a laboratory experiment to investigate the effect of lighting on attention. Participants took part in either a brightly lit or a dimly lit room and completed a listening task to test attention levels. Suggest one participant variable that could affect Xiu’s experiment. [2] Imagine carrying out this research before answering the question. This will help you think about the process participants would go through. Clearly state a participant variable which could impact Xiu’s experiment (e.g. participants could have different levels of listening skills so the task may be easier for some). Then say how this participant variable could affect the results (e.g. differences in scores on the listening task may be due to the pre-existing listening skills of the participant). Matched pairs Participants are matched for variables that could affect the results. Then, each participant takes part in only one condition of the independent variable. ▼ Table 5.5 Evaluating matched pairs designs Strengths Weaknesses Validity: Participant variables are controlled. Validity: It is questionable whether all relevant variables can be matched. Validity: There are no problems with order effects. It can be difficult (and time-consuming) to find and match participants. Links to studies » Bandura et al. (aggression) matched children on pre-existing levels of aggression. » Baron-Cohen et al. (eyes test) matched 14 individuals from the general population on IQ in Group 4 with the AS or HFA participants in Group 1. NOW TEST YOURSELF 5.3 Outline what is meant by order effects using any example. [4] 5.4 Erla is conducting an experiment to investigate if people enjoy a movie more if they have read a positive review before the film. Ten participants were asked to read a positive review before watching the film and ten participants did not read a review before watching the film. After the film, they were asked to rate how much they enjoyed the film a Briefly explain the experimental design used in Erla’s experiment. [2] b Explain one disadvantage of using this experimental design for this study. [3] SKILLS BUILDER In Baron-Cohen et al. (eyes test), explain one reason for having a matched pairs design. [2] You need to provide an explanation of why Baron-Cohen et al. used a matched pairs design. Show your knowledge of the study by including details of the sample in the matched groups. Consider the strengths of the design when justifying it to show your understanding of research design. Baron-Cohen et al. used a matched pairs design in Group 4 to eliminate the confounding influence of other variables (Generic) – for example, the effect of intelligence quotient on theory of mind (Link). 5.1.3 Randomised control trials Referred to as the ‘gold standard’ for clinical and health research. Randomised control trials (RCTs) use a variety of techniques to increase validity when testing a new drug, treatment or intervention. » Researchers can isolate the cause of any improvement to ensure it is due to the drug rather than the expectancy effect. » Participants are randomly allocated to either the experimental condition (real drug/intervention) or the control condition (placebo drug/intervention). » The placebo group is administered a treatment with no active ingredients. 60 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433_CH05.indd 60 17/08/23 2:29 PM 5 Research methodology » Participants are not informed of which drug has been given (real drug or placebo), known as a single-blind design. » Measures of clinical symptoms are taken before and after treatment. » Placebo groups may experience significant improvement over time (the placebo effect). Any significant difference in the improvement between the experimental and control groups will be due to the independent variable (the active ingredient in the real drug). » In a double-blind design, participants and researchers (measuring the severity of participants’ symptoms) are unaware of whether the participants are in the placebo group or the treatment group. NOW TEST YOURSELF 5.5 Outline what is meant by the placebo effect.[2] SKILLS BUILDER Katarzyna would like to test the success of a new drug to support patients with anxiety. Suggest why a randomised control trial would be a suitable method. [2] Clearly outline the benefit of using this method. For example, ‘Katarzyna is able to isolate the cause of any improvement by using a single-blind design.’ Link to Katarzyna’s research to show a developed understanding: ‘This ensures any improvement in anxiety is due to the new drug rather than the participant expecting anxiety to improve’. ▼ Table 5.6 Evaluating RCTs Strengths Weaknesses Validity – there is increased objectivity as experimenter bias and demand characteristics are reduced. Ethics – valid informed consent is not possible. This method is reliant on participants not knowing which condition they are in. Validity – interventions (e.g. treatments and therapies) are tested in a controlled way. Ethics – participants assigned to the control group do not have access to treatments that could improve their wellbeing. SKILLS BUILDER Chen has been suffering from chronic pain in his back. He has been placed in a single-blind randomised control trial to test the effectiveness of a new physiotherapy on pain measures versus traditional methods. Explain one ethical issue relating to randomised control trials. Refer to Chen in your answer. [2] Describe why it is an ethical issue and link clearly to Chen. The ethical issue of valid informed consent should be developed and clearly linked. For example, ‘It is not possible for Chen to know if he is in the new physiotherapy group or in receipt of traditional treatment as participants are not informed of their condition in a single-blind design.’ 5.1.4 Self-reports: questionnaires Self-reports allow participants to respond to questions about their beliefs and opinions, and discuss their behaviours. Researchers should consider the method used to ask questions (questionnaire or interview) and the format of the questions (open or closed). Features of questionnaires » Questionnaires can be completed by hand or distributed digitally online. » How questions are asked depends on the type of response/data the researcher wants. » Data can be quantitative (numerical) or qualitative (with detail). There are advantages and disadvantages to both these types of data (see pages 74–75). Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433_CH05.indd 61 61 17/08/23 2:29 PM ▼ Table 5.7 Evaluating questionnaires STUDY TIP Strengths Weaknesses Questionnaires can obtain views from a large sample. Participants may not elaborate on answers when writing, limiting depth of the data. Anonymity can lead to more honest answers. Participants may give socially desirable answers, not reflecting their own views/beliefs. Things to consider: » Leading questions should be avoided to increase validity as these could suggest a correct answer. » Questions should be clear and understandable, so they should be checked to avoid ambiguity. » Anything offensive or upsetting in the questions should be avoided to prevent distress to participants. SKILLS BUILDER Ezra is planning a case study of a child with a phobia of balloons. Suggest one way Ezra could collect data from the child’s parents, other than by interview. [2] Have you conducted a questionnaire? An effective way to learn more about this method is to carry out your own study. You can create questionnaires online using websites, or write one by hand and distribute face to face. Pick a topic you want to learn more about (phobias, personal space or even current issues, such as attitudes about climate change). Once data is collected, evaluate what went well and what barriers to success you experienced. Although this question does not state self-report, this is the only way to gather data on a person’s attitudes, opinions or experience – so an alternative selfreport method other than interview should be suggested. You could develop your answer by referring to types of questions asked or how it would be distributed to the parents. For example, ‘A questionnaire could be sent to parents through the post asking them to detail which types of balloons the child is most frightened of.’ Question types Closed questions Closed questions offer pre-determined answers for the participant to choose from. There are several forms: » Yes/No – for example, Do you doodle while carrying out tasks? Yes/No » Category choice – for example, How many times do you doodle per week? 1–5, 6–10, 11–15, 16+ » Likert/rating scale – participants circle/tick the response to show the extent they agree with a statement. For example: I find doodling while working increases my concentration. Circle the response that best fits your view: 1 2 3 4 5 1 = Completely disagree, 2 = Disagree, 3 = Neither agree nor disagree, 4 = Agree, 5 = Completely agree A simple yes/no response may not provide options reflecting the participants’ experiences with doodling, lowering validity. A Likert/rating scale allows participants to provide more perspective. Dichotomous questions (with two answers) can be helpful if you want the participant to ignore questions not relevant to them. For example, ‘If yes, please answer questions 2–4’ (developing on their experience of doodling). ‘If no, please continue to question 5.’ Forced/fixed-choice scales do not allow answers like ‘unsure/undecided’ and are intended to ‘force’ the participant to make a response (e.g. Kouzes and Posner’s Leadership Practices Inventory; see page 238). 62 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 62 14/08/23 7:19 PM 5 Research methodology ▼ Table 5.8 Evaluating closed questions Strengths Weaknesses Data is quantitative and can be analysed (e.g. mean, median, range) and displayed visually (e.g. using a bar chart). A limited choice of categories can reduce validity. Forced choice questions prevent participants from avoiding questions. Participants may not be able to freely express their opinions. Open questions » Participants can express their opinion freely without pre-determined responses. » ‘Why’, ‘describe’ and ‘how’ are used in the questions to give detailed, qualitative answers. ▼ Table 5.9 Evaluating open questions Strengths Weaknesses Data is qualitative so can give more insight. Data is harder to analyse. Participants can give different opinions, allowing researchers to understand the complexity of an issue. Data may be open to interpretation. SKILLS BUILDER Milgram (obedience) interviewed participants at the end of the study. Suggest why it could have been better for Milgram to conduct a questionnaire. [2] This question requires you to show understanding about what could have been done differently in the research by Milgram. Review the differences between these two self-report methods and in your answer recognise the benefits of questionnaires in relation to Milgram’s investigation. For instance, questionnaires would ensure the same questions are asked to each participant, unlike unstructured interviews which vary questions between participants. Questionnaire distribution Online: sending out email requests/online advertisements to complete online. » Strength: access to a large group and easily completed/returned. » Weakness: only targets those online. In person: approaching face to face and asking them to complete there and then. » Strength: lower costs. » Weakness: limits the sample to those available at the time. Postal: sent via the postal system to be returned. » Strength: can target specific groups. » Weakness: expensive and takes time for people to return. Links to studies » Hölzel et al. (mindfulness and brain scans) used the Five Facets of Mindfulness Questionnaire (FFMQ). » Pozzulo et al. (line-ups) asked parents to estimate how long their child spent watching cartoons each week via a questionnaire.

Describe how Hasna could conduct this study to collect quantitative and qualitative data. [10] Key features of self-reports you could include in your answer: » Detail the procedure (including instructions). » Identify the question format (both open and closed to collect quantitative and qualitative data). » Identify the total amount of questions. »Outline what questions will be asked (e.g. How many minutes per day do you use social media accounts?). »Outline question scoring and interpretation of key questions. Highlight the use of a questionnaire by describing how it could be distributed (online, in person, by post). NOW TEST YOURSELF 5.6 Hölzel et al. (mindfulness and brain scans) gave participants a questionnaire to measure the five facets of mindfulness. Explain how the use of this measure affected reliability in this study. [2] 5.7 Alfie is using a questionnaire to investigate parents’ opinions on toy preferences in young children. a Suggest one closed question that Alfie could use in his investigation. [2] b Suggest one disadvantage of using a questionnaire in this study. [2] 5.1.5 Self-reports: interviews Types of interview Structured Fixed questions are pre-prepared and every participant receives the same questions in the same order. » Strength: standardised as all participants receive the same questions, increasing reliability. » Weakness: do not allow participants to elaborate on interesting answers. Unstructured There is no pre-preparation. Questions are asked depending on the direction in which the discussion goes. » Strength: allow researchers to gain an insight into the area they are researching, not constrained by set questions. » Weakness: there is more risk of researcher bias. Semi-structured Some structured questions and some unstructured questions: » Strength: allow researchers to gain insight into the area. » Weakness: at more risk of researcher bias. SKILLS BUILDER Nadine is conducting a study about people’s experience of back pain. Nadine plans to collect data using a questionnaire. Suggest one reason why it may be better for her to use an interview to collect this data. [2] When considering answers, think of the group being studied and why an interview would be more accessible to this group. For example, with this target sample: 64 » People with bad back pain may find writing answers more difficult than talking about it. » With interviews, researchers can tailor questions to the individual’s needs, making questions more fitting to that person’s experience of back pain. »Non-verbal cues can be noted (grimaces/facial expressions), which may indicate pain being experienced. Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 64 14/08/23 7:19 PM 5 Research methodology Access to participants Telephone: can be quicker and more cost-effective than face-to-face interviews, as travel to meet participants is not required. Some participants may not feel comfortable speaking over the phone and less willing to speak indepth. However, there are no non-verbal signals (e.g. facial expressions) in the conversation as it is not face-to-face. Face to face: researchers can gather information on non-verbal communication (e.g. gesture, posture), increasing the validity and providing cues about emotional state. Face-to-face interviews may be impractical for those with limited mobility or transport. ▼ Table 5.10 Evaluating interviews Strengths Weaknesses Interviews can gather rich, in-depth data. There is an increased likelihood of socially desirable answers as participants will be afraid of being judged. The participant can explain their behaviour. Researchers have to be cautious of leading questions. Links to studies » Milgram (obedience) conducted interviews with participants after the study to ask them about their obedience. » Dement and Kleitman (sleep and dreams) occasionally interviewed participants after their dream recall. Psychometric tests » Psychometric means ‘measure of mind’. » Psychometric tests are designed to be valid and reliable measures of individual differences (e.g. personality, aptitude, knowledge or skills). » They are standardised on large samples to establish average scores. » Individual scores can be compared to the norm, revealing whether they score higher or lower than average. Valid psychometrics provide a range of scores (very low to very high), giving a normal distribution. » Some tests do not differentiate between people well (e.g. the range of scores is low). If the majority of scores are high, there is a ceiling effect as people are unable to achieve any higher. If everyone receives a low score, this is known as a floor effect. These effects lower validity as participants cannot be ranked. An intelligence test, for example, must not be too hard (to avoid floor effects) or too easy (to avoid ceiling effects). ▼ Table 5.11 Evaluating psychometric tests Strengths Weaknesses Psychometric tests use numerical data, which is objective. Participants may respond to demand characteristics. Individuals can be tested against the normal distribution of the population. If assessed under stress, it can affect performance. Links to studies » Baron-Cohen et al. (Eyes Test) used the Revised Eyes Test to measure theory of mind. » Perry et al.

SKILLS BUILDER Saavedra and Silverman (button phobia) conducted an interview to investigate the phobia of a nineyear-old boy. Outline how Saavedra and Silverman conducted their interview. [2] Key terms could be used to show understanding of the method. Saavedra and Silverman utilised a semistructured interview with the boy and his mother using the Anxiety Disorders Inventory Schedule. This method allowed the researchers to assess the criteria for diagnosis of phobia. NOW TEST YOURSELF 5.8 Describe two disadvantages of self-reports. [4] 5.9 Perry et al. (personal space) used a psychometric measure (the Interpersonal Reactivity Index) to measure cognitive and affective dimensions of empathy. Outline one strength of using a psychometric test in this study. [2] Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 65 65 14/08/23 7:19 PM 5.1.6 Case studies Features of case studies » Case studies are detailed investigations involving a single ‘unit’: one individual or a group/organisation of people. » This type of study is useful when researching rare cases. » Data is gathered using a number of different techniques (interviews, observations and psychometric tests). Triangulation is often used. » Data is often gathered over an extended period of time (making them longitudinal studies). » Both qualitative and quantitative data can be gathered. » Data can be gathered from the participants but also from family, friends and official records (school, psychiatric, workplace, etc.). » Case study reports often begin with a case history. STUDY TIP Active learning skills can be developed leading to improvements in understanding. Become more involved in the information reviewed by critically evaluating it. Consider the implications and note any questions you have about the material covered. SKILLS BUILDER Parminder is studying a man who has problems with his short-term memory. He is unable to remember new people or facts. Parminder is collecting data using techniques including interviews and observations. Suggest one advantage of using a case study in this [2] study. Acknowledging that the individual can be studied in detail is correct, but also basic. To fully answer the question, link your answer to the scenario. For example, ‘By looking in depth at the case of shortterm memory loss, Parminder gains a greater insight into how he is affected using interviews and observations to gather detailed data. She can learn about which parts of his memory are most affected (people, places, routines) and the impact this has on his everyday life.’ Link to study Saavedra and Silverman (button phobia) documented the clinical case of a nine-yearold Hispanic-American boy’s phobia of buttons. The treatment using exposure-based cognitive-behavioural therapy and interviews with the boy and his mother were included. SKILLS BUILDER Baron-Cohen et al. (eyes test) conducted a laboratory experiment to investigate the theory of mind of adults with high-functioning autism. Alternatively, they could have conducted a case study. Explain why using a case study would have been less suitable for this research. [2] You could develop an answer to this question by justifying why a case study would be inappropriate based on the research aims. For example, ‘Baron-Cohen et al. tested adults with autism to see if the revised eye test works. A large sample was needed so results could be generalised to the wider target population of individuals with autism. If a case study was used in this research, improvements in the test would not have been shown and findings could not be generalised to others.’ ▼ Table 5.12 Evaluating case studies 66 Strengths Weaknesses Validity – a case study provides rich and detailed information giving insight into an individual’s psychology. Validity – researcher bias can occur as they work closely with the participant. There would be less objectivity. Validity – triangulation of methods helps reduce researcher bias and increases validity. Reliability – case studies are difficult to replicate as they are detailed analyses of one individual/small group. NOW TEST YOURSELF 5.10Outline one strength and one weakness of conducting a case study, using Saavedra and Silverman (button phobia) as an example.

Overt or covert This feature concerns what participants are aware of: » Overt observation is when the participants know they are being observed. » Covert observation is where the participants do not know they are being observed. ▼ Table 5.13 Evaluating overt and covert observations Strengths Weaknesses Overt observations are more ethical as participants know they are being observed, which avoids deception. Overt observations may produce demand characteristics as participants know they are being watched so may act unnaturally. Covert observations avoid demand characteristics as participants do not know they are being observed. Covert observations are less ethical as participants do not know they are being observed and cannot withdraw. STUDY TIP Hassett et al. (monkey toy preferences) carried out observations of rhesus monkeys in the outdoor area of their enclosure at the research centre. Carry out your own observation on a variety of animal species using live feeds from the Smithsonian’s National Zoo and Conservation Biology Institute: https://nationalzoo. si.edu/webcams Participant or non-participant This feature concerns the observer’s role in the setting of the observation: » Participant observation is when the observer becomes part of the community (or group of people) they wish to observe (can be overt or covert). » Non-participant observation is when the observer is not a part of the group and they observe from a distance (can also be overt or covert). ▼ Table 5.14 Evaluating participant and non-participant observations Strengths Weaknesses Participant observers may gain a greater understanding of the Participant observers may become too involved with participants’ behaviour as they are involved in the situation. those they are observing and become less objective. Non-participant observers are more likely to be objective as they are not personally involved in the situation. Non-participant observers may miss behaviours as they are observing from a distance. SKILLS BUILDER Rosie is using an observation to investigate children’s play behaviour in a public park. Outline one ethical issue of this research. [2] Consider ethical guidelines and put them into context. Rosie is conducting her observation in a public park. This does not pose an issue of informed consent as people should expect to be observed in public. Therefore, Rosie could focus on privacy and maintaining confidentiality of participants (e.g. not revealing identifiable features of the park or children). Structured or unstructured This feature concerns the data collected: » Structured observations have behavioural checklists in place before beginning the observation. A tally is kept of behaviours. Researchers plan what will be observed. » Unstructured observations do not include planning before the observation and the observer records behaviour that is relevant to the aim of the research as it occurs.

Structured observations are more reliable than unstructured ones as the behaviours are decided in advance and operationalised. Inter-rater reliability can be assessed. Structured observations may not include all relevant actions within the behavioural categories. Link to study Piliavin et al. (subway Samaritans) recorded whether the helpers where male/female and black/white using a pre-determined checklist. Naturalistic or controlled This feature concerns the setting of the observation: » Naturalistic observations are conducted in real-world settings. » Controlled observations are conducted in laboratory settings. ▼ Table 5.16 Evaluating naturalistic and controlled observations Strengths Weaknesses Naturalistic observations record behaviour that is likely to be normal, increasing ecological validity. Naturalistic observations are harder to control for extraneous variables that may affect participants’ behaviour, lowering the validity. Controlled observations can be replicated by others when using the same behaviour schedule. Controlled observations may be less natural if participants are aware of the controlled setting. SKILLS BUILDER Darcie is aiming to observe emotional responses to different films at the cinema. She is planning a structured observation with fixed behaviours to record. Describe how Darcie could conduct her study. [10] Key features of observations could be included to develop your answer: »Review the location of research (naturalistic, cinema, types of screening). » Detail the role the researcher will play in research (participant or non-participant). » Describe how collection of data will be structured (behavioural checklist). »Outline whether it will be a covert or overt observation. Highlight it as an observation, so describe the behavioural categories (emotional responses and how they are recognisable). Links to studies » Bandura et al. (aggression) used covert observation – the children did not know they were being observed. It was a non-participant observation as a one-way mirror was used. It was a controlled observation in a laboratory setting (same toys and timings). It was a structured observation as a behavioural checklist was used (imitative physical aggression). » Piliavin et al. (subway Samaritans) was a covert observation – the passengers did not know they were being observed. It was a participant observation as the model and observers were bystanders and passengers. It was structured as each observer recorded pre-determined items (race, sex, location of helpers, etc.) and naturalistic as the subway was an everyday situation for the participants. 68 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 68 14/08/23 7:19 PM 5 Research methodology NOW TEST YOURSELF 5.12 Give one similarity and one difference in the type of observations conducted by Bandura et al.

This is a key skill for becoming an independent learner. Features of correlations » Correlational studies look at the relationship between variables. » Variables that are correlated are called co-variables. » For each participant, two sets of data are gathered which can be plotted on a scatter graph to see the correlation between the two measures. » Correlations are often used to investigate topics where it is not practical or ethical to manipulate variables. » Various methods are used to collect data in correlations (questionnaire, observation, etc.). Links to studies » Dement and Kleitman (sleep and dreams) investigated the relationship between time spent in REM sleep and the number of words in a dream narrative. » Hölzel et al. (mindfulness and brain scans) investigated the relationship between time spent on mindfulness exercises and increases in grey matter concentration. » Baron-Cohen et al. (Revised Eyes Test) investigated the relationship between Autism Spectrum Quotient (AQ) and Revised Eyes Test scores. Operationally defining co-variables Co-variables should be operationalised by stating what the variables are and how they will be measured. For example: » Co-variable 1: scores on a test (out of 50). » Co-variable 2: amount of hours spent revising in one week. Clearly operationalised variables allow for testable hypotheses. Positive, negative and no correlation Correlations can be positive or negative. This is how the variables interact with each other. Positive correlation (Figure 5.1, left) is when the scores of co-variables move in the same direction (increase or decrease together). For example, Dement and Kleitman (sleep and dreams) found the amount of words used to describe a dream increased as the time spent in REM sleep increased. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 69 69 14/08/23 7:19 PM Negative correlation (Figure 5.1, middle) is when the scores of the co-variables move in opposing directions (as one increases, the other decreases). For example, Baron-Cohen et al. (eyes test) found that the higher the autism spectrum quotient, the lower the score on the revised eye test. No correlation (Figure 5.1, right) is when no consistent relationship is found between scores. For example, Hölzel et al. (mindfulness and brain scans) found no correlation in the time spent on mindfulness activities between the weekly MBSR sessions and grey matter concentration. SKILLS BUILDER Kayden is testing the hypothesis that ‘There will be a positive correlation between level of brain activity and how much a person can recall.’ Each participant is asked to describe an event that happened one week ago while having their brain scanned. Explain whether Kayden will be able to conclude that greater recall causes more brain activity. [2] Begin an explanation with what is known: ‘Kayden is looking for a relationship between variables.’ Develop your answer with knowledge and understanding of the weakness of correlational studies. `You cannot demonstrate cause and effect relationships from correlations as there may be intervening variables explaining why the co-variables are linked’. Clearly link back to the scenario as ‘In Kayden’s research, brain activity may be affected by other variables, such as caffeine intake or amount of sleep.’ Correlation coefficient The correlation coefficient is a number between 0 and 1 that expresses how strong a correlation is. If the number is close to 0, there is no close relationship between the two variables. The closer the coefficient is to 1 (for a positive correlation) or –1 (for a negative correlation), the stronger the correlation is. A correlation of +0.75/–0.75 is considered a strong correlation. ▼ Table 5.17 Evaluating correlations Strengths Weaknesses Correlations can provide information that may prompt further research. Correlations do not tell us why that relationship has occurred. Causality cannot be assumed. Correlations allow areas to be researched when it is impractical or unethical to manipulate variables. A third variable not being measured may have influenced the relationship.

[2] 5.15 Jean-Luc is planning to investigate if amount of exercise affects quality of sleep. a Suggest one reason why it is more appropriate to conduct a correlational study than an experiment to test this idea. [2] b Explain what the term positive correlation means with reference to Jean-Luc’s investigation. [2] 5.1.9 Longitudinal studies Features of longitudinal studies » Longitudinal design describes studies conducted over an extended period of time. » Successive measures at different points in time can track the development of individuals. » Changes in thoughts, feelings and/or behaviours can be documented. » Various techniques can be used (psychometrics, experiments, questionnaires, etc.). SKILLS BUILDER Huang is testing the effectiveness of a programme designed to increase school attendance in children aged 8–11 years old. Attendance is reviewed every four weeks. Suggest how validity may be affected by using a longitudinal design within this study. [2] STUDY TIP Time is an important feature for this method. It is also important to keep track of time in your AS and A Level studies. Have you written a revision timetable? Calculate the time you have available and divide the time you have between topics in your assessment. Validity is how well a measure actually measures what it intends to measure. It can be affected positively and negatively, so strengths can be considered. For example, participant effects are avoided as the same group of participants are followed in longitudinal designs. In Huang’s research, the same children’s attendance is reviewed every four weeks. Links to studies » Hölzel et al. (mindfulness and brain scans) collected data over an eight-week period to compare the effectiveness of MBSR. » Saavedra and Silverman (button phobia) assessed the boy’s behaviour before, during and after treatment, including follow-up sessions at 6 and 12 months. ▼ Table 5.18 Evaluating longitudinal studies Strengths Weaknesses Longitudinal studies have an advantage over crosssectional studies, where sub-samples from a population are tested and compared at the same point in time. Therefore, longitudinal designs do not have participant variables as the same individuals are followed over time. Participant attrition is more likely as participants may move away or lose contact. Longitudinal studies allow topics such as child development to be studied. Temporal validity may impact on the findings as social changes occur. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 71 71 14/08/23 7:19 PM SKILLS BUILDER John is interested in testing the cognitive abilities of 6-7- and 8-year-olds. He is interested in their mathematics, reasoning and problem-solving abilities. Describe how John can conduct a longitudinal study to investigate the development of these cognitive abilities. [10] »Review when the children will be tested (independent variable). » Highlight the cognitive tests to assess the children at each age (a maths test, a reasoning task and a problem-solving task). Develop these into the procedure of the study. » Describe the sample (size of sample, sample method). »Outline the procedures used to collect data from each child (standardised). Highlight it as a longitudinal study, so include reference to revisiting the same sample to retest and compare their scores from previous tests. NOW TEST YOURSELF 5.16 Explain one strength of longitudinal studies relating to validity. [2] 5.17 Explain how Saavedra and Silverman (button phobia) used a longitudinal design. [2] 5.2 Methodological concepts 5.2.1 Aims, hypotheses and variables Aims An aim is a statement describing the purpose of research. For example, Fagen et al. (elephant learning) aimed to investigate whether secondary positive reinforcement could be used to train elephants to complete a trunk wash. Hypotheses A hypothesis is a testable statement predicting the outcome(s) of an investigation. For example, Perry et al. (personal space) predicted preferred interpersonal distance following oxytocin administration would differ depending on whether the person was high or low in empathy. Operationalisation Variables need to be operationalised. This means clearly defining the independent variable (IV) and dependent variable (DV) in an experiment or the co-variables in a correlation. STUDY TIP Knowledge of our cognitive processes (‘How am I thinking about this?’) and questioning (‘Would it be better if I thought about this differently?’) is needed in A Level revision. This gives us the opportunity to monitor thinking processes relating to our learning. Operational definitions are needed to describe how the variables will be observed or measured. A researcher interested in the effects of sleep deprivation (IV) on level of stress (DV) must consider the following: » What is sleep deprivation? Is it missing one night’s sleep or is it having less than 10 hours’ sleep over a 72-hour period? » How will the level of stress be measured – a score from a questionnaire or a physiological measure (e.g. heart rate monitor, beats per minute)? Making these choices clear in the hypothesis is operationally defining the variables. Types of hypotheses and how to recognise them » Experimental hypothesis: predict an outcome for experiments (IV and DV present). ‘Participants who experience 24 hours’ sleep deprivation will have significantly higher levels of stress as measured by a heart rate monitor compared to participants who experience no sleep deprivation.’ » Alternative hypothesis: the alternative to the null hypothesis (see below) and used for all types of research (including correlations). ‘There will be a significant relationship between the reaction time in seconds and amount of sugar consumed (in grams) in the previous two hours.’ 72 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 72 14/08/23 7:19 PM 5 Research methodology » Directional hypothesis: states the kind of difference/correlation – higher/lower, better/worse or positive/negative. » Non-directional hypothesis: states there will be a difference/correlation but does not state the direction of the difference, effect or relationship. » Null hypotheses: states that results are due to chance (no significant relationship/difference) and lack statistical significance. SKILLS BUILDER Liam’s hypothesis is: There will be no significant difference between performance on a test in the morning compared to the afternoon. Identify whether this is an experimental or a null hypothesis. Include a reason for your answer. [2] Give a justification for the decision in your answer. Identify the type of hypothesis clearly: ‘Liam’s hypothesis is a null hypothesis.’ You could then explain your reason: ‘This is because Liam has stated there will be no difference between performance on a test in the morning compared to the afternoon.’ Data analysis Inferential statistics show the probability (p value) that the results are due to chance. Data analysis shows which hypothesis should be accepted (alternative or null). When analysis is complete, the researchers will reject the null hypothesis if the p value is less than 0.05 (1 in 20) and accept it if it is more than 0.05 (1 in 20). SKILLS BUILDER Describe different types of hypotheses in research, using any examples. [6] Include key terms as you review at least three types of hypotheses to show an understanding of the various types used in research. Structure your answer to make your description of each type of hypothesis clear. For example, a directional hypothesis predicts (Terminology) which level of the IV will perform ‘better’ in an experiment (Outline). Dement and Kleitman predicted more dreams would occur in REM sleep than NREM sleep (Example). NOW TEST YOURSELF 5.18 Bandura et al. (aggression) hypothesised that observing a non-aggressive model would inhibit aggressive behaviour. Identify whether this is a directional or non-directional hypothesis. Justify your answer. [2] 5.19 Sara wants to see whether confidence in their doctors affects people’s adherence to medical requests. Write an operationalised, directional hypothesis for Sara’s study. [2] 5.2.2 Controlling of variables A teacher conducts a study to find out whether students can complete revision effectively while listening to music. The study involves two groups: ‘revision in silence’ and ‘revision with music’: » IV: music or no music » DV: score on the test. The teacher wants to know the effect of the IV (music during revision) on the DV (test scores). STUDY TIP Within your revision timetable, plan in time for breaks, rewards and a good amount of sleep. Revision is best when well rested. But what if other factors affected the DV? The room the groups are tested in might be different (one cooler than the other), which could affect students’ attention. Consequently, the teacher would not have tested what they intended to test. Instead, the influence of another (extraneous) variable could be the cause of any difference found. Control is important for validity. Therefore, experimenters should control as many extraneous variables as possible. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 73 73 14/08/23 7:19 PM Standardisation One control is to standardise the procedure to ensure participants have the same experience. » The only difference should be what is manipulated (the independent variable). » Participants should be given the same information and instructions. SKILLS BUILDER Explain one control used in the research by Bandura et al. (aggression). [3] One control in Bandura et al.’s research was the use of a matched pairs design. An explanation of why it was used (‘to control for participant variables’) could be given. To develop your answer further, justify why: ‘Matching children in each group based on pre-existing levels of aggression ensures all groups have an equal level of aggression before beginning the test. This lowers the chance of participant variables affecting the dependent variable (imitative aggression), increasing validity.’ Uncontrolled variables Situational variables » Factors in the environment can act as extraneous variables. » In the example above, participants in the ‘no music’ condition may have taken the test in a different room with more distractions, which could have affected their test scores. » Situational variables can be controlled using standardised procedures, ensuring the same conditions for all participants. SKILLS BUILDER Define situational and participant variables, using any examples.[6] These questions will stretch your knowledge and understanding of key concepts in research. Here you could show a developed understanding of both situational and participant variables by elaborating and giving clear examples from research. Balance is important in your answer. Dedicate time to both types of variable. Participant variables » The participants in one group may be different from participants in the other group in important ways. » In the example above, one group may have higher levels of confidence in the subject on the test. Intelligence and experience are characteristics of participants that are variable. » Participant variables can be controlled using random allocation to groups, a matched pairs design or a repeated measures design giving an even spread of important characteristics. NOW TEST YOURSELF 5.20Outline what is meant by controlled variables. 5.21Orla is investigating whether there is a difference in employees’ performance working in teams rather than alone. Suggest how participant variables may affect her results. [2] [2] 5.2.3 Types of data Quantitative data » Quantitative data describes human behaviour and experience using numbers and statistical analysis. » Quantitative data can be measured. » Examples include: a score recorded for each participant, the time taken to complete a task. 74 STUDY TIP Organise your notes into knowledge and understanding, application, and analysis and evaluation. Use different coloured pens and highlighters to help separate revision notes. Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 74 14/08/23 7:19 PM 5 Research methodology ▼ Table 5.19 Evaluating quantitative data Strengths Weaknesses Scores can be compared. Results can be compared if the study is replicated. It does not always allow us to understand what a participant is thinking or feeling. Scales may limit how participants can respond, reducing validity. Numbers and statistics are more objective and less prone to researcher bias. It reduces behaviour to a single number, failing to find out why a participant has behaved a particular way. It is more scientific as statistical tests can be conducted. Link to study Andrade (doodling) recorded the mean number of correctly recalled names and places, false alarms and memory scores. Qualitative data » Qualitative data deals with descriptive, in-depth detail of behaviour and experience. » Qualitative data is not measured. » Examples include: descriptions of events, quotes from participants, descriptions of responses to a task. Some studies produce a mixture of qualitative and quantitative data. ▼ Table 5.20 Evaluating qualitative data Strengths Weaknesses Data provides an in-depth understanding of the thoughts and feelings of participants. Analysis is prone to researcher bias as the interpretation is more subjective. Data can be rich in detail and insightful, so not reductionist. Statistical analysis cannot be made, so it is less scientific. Researchers can gain an understanding of why people behave in a particular way. Studies are harder to replicate so findings can be less reliable. Link to study Dement and Kleitman (sleep and dreams) gathered qualitative data through participants’ descriptions of dreams. Subjective data » Subjective data can be influenced by personal thoughts, feelings or opinions. » This is more likely with qualitative data, which requires interpretation. » Saavedra and Silverman (button phobia) used an interview with responses given on a ‘feelings thermometer’. This data is subjective as the boy with the button phobia gave his own personal judgement as to which number represented his feelings. Objective data » This is data that is unbiased and factual. » Researchers can improve objectivity by getting another researcher to interpret the data, removing researcher bias. » Quantitative data is often thought of as objective. Some are and some aren’t. For example, a rating scale requires a person to score themselves. This is quantitative but it is subjective. » Hölzel et al. (mindfulness and brain scans) collected data with an MRI scan using voxel-based morphometry. Analysis of this data was objective. SKILLS BUILDER Identify the quantitative findings from the research by Piliavin et al. (subway Samaritans). [2] One mistake that might be made is to review the quantitative data (demographic characteristics, frequency of helping) rather than what was found. For example, 90 per cent of people helping were male; the median helping time in the ill condition was 5 seconds and in the drunk condition was 109 seconds. NOW TEST YOURSELF 5.22Outline what is meant by qualitative data, using an example. [2] 5.23 Identify two pieces of quantitative data collected by Fagen et al. [2] Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 75 75 14/08/23 7:19 PM SKILLS BUILDER Tristan is planning to investigate the types of dreams people have, using an interview. He wants to collect both quantitative and qualitative data. Describe how Tristan could conduct a semi-structured interview. [10] Key features of interviews you could include: » Detail the procedure (including instructions). » Identify the question format (both open and closed questions would be needed to collect quantitative and qualitative data). » Identify the total amount of questions. »Outline what questions will be asked (e.g. How frequently do you have scary dreams?). » Detail the scoring and interpretation of questions. Highlight it as an interview by describing whether it is a face-to-face or telephone interview. 5.2.4 Sampling of participants Sample and population Researchers cannot test everyone. A sample is selected to represent the target population and findings from the studied group should be generalisable to the target population. When evaluating generalisability of research, the sample tested and how it was selected can be considered. A researcher can choose from different sampling techniques to recruit participants. STUDY TIP Explaining concepts and research to someone else is a good test of your knowledge. Revising in pairs or in groups will help develop your understanding. Sampling techniques Opportunity: selecting those available at the time of research. » Strength: a large sample can be obtained quickly and without much effort. » Weakness: researchers may choose people who look suitable and therefore bias the sample. Link to study Hölzel et al. (mindfulness and brain scans) recruited an opportunity sample of 33 right-handed, healthy adults from four MBSR courses at the Centre for Mindfulness. SKILLS BUILDER Sharmin is conducting research on the patient– practitioner relationship at a local health centre. She believes a random sample of patients would be the best technique. Give one reason why a random sample would be better than an opportunity sample in this research. [3] You may want to explain why random sampling is better in this situation and use key terms to show your understanding. By conducting an opportunity sample, Sharmin would use patients who are attending the local health centre on the day she chooses to carry out her research. It would be those patients available at the time. This would not be representative of all patients at the centre as those seeing doctors and nurses on other days would not be included. Sharmin could use a computerised random patient generator to create, a random sample of all patients registered at the healthcare centre. This would make the findings more generalisable to the target population. Random: each participant is randomly selected from the target population. Every member of the group has an equal chance of being selected (e.g. the names of every member of the group is put in a hat and the required number of names is picked out). 76 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 76 14/08/23 7:19 PM 5 Research methodology » Strength: more likely to be representative. » Weakness: some of the people picked may not want to take part and will need replacing. Volunteer (self-selecting): asking for volunteers to take part in research through advertisements. » Strength: useful when the research requires participants of a specific type or with a particular experience. » Weakness: people may not see the advert or make time to reply, or they may just ignore it. Those who do volunteer may be different from those who do not choose to volunteer. Link to study Milgram (obedience) used a newspaper advertisement in the New Haven district. Volunteers responded to take part in an experiment on learning and memory. SKILLS BUILDER Outline the differences between an opportunity sample and a volunteer sample, using any examples to support your answer. [6] To ensure your differences are clearly identifiable, you could use a sentence starter such as ‘One difference between…’. This gives structure and makes your points clear. Differences can be about how participants are selected for research or evaluative issues: »Volunteer samples select themselves for research, whereas opportunity samples are available at the location of research. »Volunteer samples may have participant bias as those selecting themselves will have different characteristics from those not wanting to take part. However, opportunity samples may have researcher bias as participants will be chosen by the researcher based on where the study is conducted. NOW TEST YOURSELF 5.24 Explain one advantage of the sampling method used in the study by Milgram. [2] 5.25 Jude is carrying out an investigation into whether college students feel happier during the day if they have had a pleasant dream the night before. Suggest one feature of the participants that Jude should consider to make his sample representative. [2] You could develop your answer by including relevant examples from the studies reviewed to demonstrate the points made. 5.2.5 Ethics and human participants Ethical guidelines Guidelines on how to treat participants are set by institutions such as the British Psychological Society and the American Psychological Association to maintain respect for participants and ensure responsibility. Valid consent » Participants should be asked if they want to take part and be given relevant information about what is involved. » Consent should be provided before collecting data. » All participants, including children, should consent. » Vulnerable groups (including children) should have consent given by family members/caregivers. STUDY TIP Locate a set of ethical guidelines from the website of the British Psychological Society or the American Psychology Association and use it to evaluate the ethics of research. Link to study Milgram (obedience) failed to get informed consent as the participants thought they were taking part in a study on learning and memory, not obedience to authority. Right to withdraw » Participants should be made aware they can withdraw from the study at any time during or after data collection. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 77 77 14/08/23 7:19 PM » There should be no pressure for them to remain in the study. » This cannot be granted if the participants do not know that they are being studied. Link to study Piliavin et al. (subway Samaritans) denied the right to withdraw as participants were unaware they were being tested on levels of helping. Minimising harm » Researchers must minimise harm to participants’ psychological wellbeing, personal values, privacy or dignity and mental health. » The risk of harm should be no greater than the participant might expect in their everyday lives. Link to study Bandura et al. (aggression) exposed children to aggressive behaviour, which could have led to negative consequences (children acting more aggressively). Lack of deception » Participants should not be deceived about the aims or misled about the study. » The use of a stooge or confederate (such as in Milgram) would be considered deception. » It is difficult to conduct research without any deception, as knowing the true aim can change a participant’s behaviour. » When deception is involved, a full debrief is needed. Link to study Deception was used in Perry et al. (personal space). In Experiment 2, participants were told they were choosing a room for a personal meeting. They were told the following week that the meeting would not take place. SKILLS BUILDER One ethical guideline is the right to withdraw. Explain how this guideline may have been broken in one core study from the Learning approach. [2] Ensure the study chosen is appropriate. Fagen et al. (elephant learning) studied animals so the ethical issue of right to withdraw does not apply. Therefore, you could discuss Saavedra and Silverman (button phobia) or Bandura et al. (aggression). Confidentiality » Participants’ data should not be passed to others who are not involved in the research and it should not be published in a way that would reveal their identity. » Participants’ names should not be included with their data. » In longitudinal research, a code number should be assigned to participants so data can be connected when returning to the research. Link to study Saavedra and Silverman’s (button phobia) case study did not include the boy’s name. Privacy » Privacy is considered within observational research. » Participants should only be observed in public situations where they might expect to be observed by others. » It is not acceptable to observe people in their own homes without consent. » Consent is required from whoever owns/is responsible for the public space (e.g. the manager of a supermarket). Link to study Piliavin et al. (subway Samaritans) carried out an observation on a subway train. As this was a public setting, privacy was not breached. Debriefing » Participants should be told what has happened, asked if they have concerns and given explanations at the end of the study. » Participants should leave the study in the same state they arrived. Link to study Andrade (doodling) debriefed participants to see if any had suspected it was a memory test. 78 NOW TEST YOURSELF 5.26 What is meant by the term confidentiality? [2] 5.27Rosa is carrying out a controlled observation into conformity. She is not informing participants of the research. Explain why it is sometimes necessary to break the guideline of informed consent, using Rosa’s research as an example.

One participant says that Carys’ questions are too distressing. Explain two ethical guidelines that are important to overcome this problem. Do not refer to minimising harm or right to withdraw in your answer. [4] Identify the ethical guidelines and give a clear link to the scenario with a detailed solution. Participants must understand the aims/procedure and give fully informed consent (Guideline). Carys’ participants may not have expected questions on environmental issues and emotions (Link). Participants should understand and agree to the aims of the research. Therefore, Carys should have told them that the questions would include ones on their emotions (Solution). Participants should be returned to their previous state after participation, but they weren’t (Guideline). After the study, Carys’ participants were still upset by the questions about environmental issues and emotions (Link). Therefore, a full debrief should have been offered to discuss their emotions relating to climate change (Solution). 5.2.6 Ethics and non-human animals Ethical guidelines Research involving ‘protected’ animal species is governed by the Animals (Scientific Procedures) Act 1986, amended in 2012. The British Psychological Society outlines guidelines for working with animals. Minimise harm and maximise benefit Researchers should minimise harm, discomfort and suffering to the animals and maximise the benefit of the research (e.g. applying findings to help other animals or humans). Replacement Alternatives to using animals should be considered where possible (e.g. computer simulations or videos of previous studies). Species (and strain) Appropriate species should be chosen (e.g. those least likely to suffer). Some animals are considered more sentient than others (i.e. have the ability to feel). Nonhuman primates should be avoided due to the high level of sentience. Numbers Researchers should use the smallest number of animals possible to meet the research aims. Animals should not be used over a long period of time as this could prolong suffering. Pain and distress » Death, disease and psychological or physical discomfort should be avoided. » An animal’s environment should be enriched where possible. » Potential harm and the benefits being gained should be balanced. Housing SKILLS BUILDER In Fagen et al. (elephant learning), explain how two ethical guidelines relating to using animals in research were followed. [4] Give enough detail from the study to show how ethical guidelines were followed. For example, ‘The elephants were able to walk away if they did not want to participate, avoiding distress’ and ‘Normal feeding patterns were also adhered to and aversive stimulation was avoided in training.’ These points could be developed to show an understanding of the study and the guidelines. The social and natural behaviour of the species should be considered. Animals who would normally live in social groups should not be isolated. Overcrowding should also be avoided to prevent stress and aggression. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 79 79 14/08/23 7:19 PM Reward, deprivation and aversive stimuli Normal feeding patterns should be adhered to and deprivation or aversive stimulation should be avoided, or kept to the minimum needed to achieve the goals of the study. SKILLS BUILDER Outline what is meant by species and housing when carrying out research with animals, using any examples. [6] Examples can be used from Hassett et al. (monkey toy preference) and Fagen et al. (elephant learning) to show the range of animal studies covered. Link clearly to species and housing, showing an understanding of the ethical guidelines. Link to study Fagen et al. (elephant learning) did not deprive the elephants while they were learning the trunk wash. Chopped banana (a treat) was selected to reinforce behaviour even when the elephants were well fed. NOW TEST YOURSELF 5.28 Describe the ethical guideline of pain and distress when conducting research with animals. 5.29 In the study by Hassett et al. (monkey toy preferences), explain how the ethical guideline of housing was upheld. [2] [2] 5.2.7 Validity Validity refers to whether the observed effect is a genuine one. This includes the extent to which a researcher has measured what they intended to measure (internal validity) and the extent to which findings can be generalised beyond the research setting (external validity). Internal validity Examples of threats to internal validity: » Social desirability bias: participants may want to present themselves in the best way possible, so answers may not represent true thoughts and feelings. » Subjectivity: the researcher’s interpretation of behaviour may be biased by personal thoughts, feelings or opinions. » Demand characteristics: participants will not behave as they usually do if they alter behaviour as a consequence of the cues in research. » Low controls: a lack of control over extraneous variables may lead to other factors affecting the dependent variable. STUDY TIP Ensure your revision is valid. Begin with the content and list all of the topics featured in the specification. Construct your revision timetable with all of the topics in mind and allocate time accordingly. Use specimen and past papers to guide you on how questions will be asked. SKILLS BUILDER Priya conducts a study on the health behaviours of students using a questionnaire. Explain what is meant by validity in the context of this research. [2] To provide enough detail on what validity is, you may use key terms and give an appropriate example from the study. ‘Validity is ensuring the measure is measuring what it intends to measure. Priya should ensure the questionnaire includes a range of health behaviours on the questionnaire, such as diet and exercise.’ Link to study Baron-Cohen et al. (eyes test) checked the validity of words/foils for each set of eyes. The words were chosen by two of the authors and judged by an eight-member team. At least five of the judges had to agree that a particular word was the correct one. 80 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 80 14/08/23 7:19 PM 5 Research methodology External validity Generalisability » It should be possible to apply findings to people other than those who participated (generalisable). » The extent to which findings can be generalised beyond the sample is sometimes referred to as ‘population validity’. » Findings should be generalised to the target population only if the sample was sufficiently representative. » Generalisability can be affected by sampling technique as random samples are more representative than opportunity or volunteer samples. Ecological validity » Ecological validity is the extent to which the results of research can be generalised from the environmental conditions created by the researcher to other environmental conditions. » Research conducted in real-life settings (e.g. field experiments) is likely to be higher in ecological validity. » We can generalise from research high in ecological validity because behaviour is natural and normal. However, studies with low ecological validity cannot be used to generalise because they are less true to real life. Temporal validity » Temporal validity is whether the results can be generalised to a different time period. » Milgram’s research was based in the 1960s and values of society at the time may have had a significant influence over obedience levels. » Social research is susceptible to temporal validity issues as values and norms change. SKILLS BUILDER In Priya’s study on the health behaviours of students using a questionnaire, one threat to validity could be social desirability bias. Explain how Priya could deal with this. [2] It is tempting to discuss how social desirability would be a problem for Priya, but this would not answer the question. The focus needs to be on dealing with the issue, so solutions should be offered – for example, hiding the aim of the research or making questionnaires anonymous. NOW TEST YOURSELF 5.30 Suggest one reason why demand characteristics may cause a validity issue, using any example. [2] 5.31 From the study by Pozzulo et al. (line-ups), describe two ways the study was valid. [4] 5.2.8 Reliability and replicability Reliability Reliability of a psychological measure (e.g. a test or scale) is the extent to which it gives consistent measurements. If an intelligence test was given to a person and a week later the same test was taken again, the same (or very similar) score should be obtained. If a very different result is obtained, the test would be criticised for lacking reliability. The reliability of an experiment is the extent to which it can be replicated. Reliability can be assessed using the following methods: STUDY TIP Revising involves reflection and observation. Look at the organisation of your notes and see if you can make them simpler and clearer. Fill in gaps in your material, otherwise this could lead to gaps in your understanding. » the test-retest method: administering the same test to the same person on two different occasions (e.g. three weeks apart) and comparing the results » the split-half method: splitting the test into two and administering each half to the same person; the scores from the two halves should be the same (if test items are balanced equally) » checking observations using inter-rater reliability: the extent to which two or more independent observers agree on the observations they have made. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 81 81 14/08/23 7:19 PM Replicability » If another psychologist can carry out a study in the same way to see if they get consistent results, it is referred to as replicable. » Replicability helps researchers show the reliability of findings. » Standardisation allows others to replicate studies. Standardisation » A set of standardised procedures and instructions can be given. These are the same for all participants to allow replication to take place. » This ensures the experience of the research is consistent for all participants. » The instructions given to participants should be identical (standardised instructions). » Procedures in research should be the same to ensure fairness and replicability. SKILLS BUILDER Sara decides to collect data on confidence of patients in their doctors, using a questionnaire. Explain how she could assess the reliability of the questionnaire. [4] Focus on how Sara could assess the questionnaire and justify why certain procedures should be followed. Within your reasoning, you should show an understanding of reliability. For example, ‘A split-half method could be used where each participant is given two halves of the same questionnaire and the results from the confidence scales compared. If the scores are similar then it suggests the questionnaire is reliable.’ SKILLS BUILDER Describe how the study by Bandura et al. (aggression) was reliable. [2] Utilise key terms to effectively answer this question. High levels of inter-rater reliability were found in Bandura et al. Two observers independently recorded participants’ behaviour using a behavioural checklist in fivesecond intervals. Their results were correlated and found to be in the +0.90 s. NOW TEST YOURSELF 5.32 Explain what is meant by reliability, using one example from the study by Andrade (doodling). [2] 5.33 George is investigating doodling behaviour of children in the classroom using an observation. Suggest how George can assess the reliability of his investigation. [3] 5.2.9 Data analysis Measures of central tendency Raw data does not tell us much until it is organised and summarised using measures of central tendency. A raw data table (e.g. scores out of 20 for a memory test with and without noise) may look like Table 5.21 ▼ Table 5.21 Raw data for word recall with and without noise 82 Word recall with noise Word recall without noise 10 16 12 14 11 15 10 14 7 17 8 17 10 17 13 16 12 17 14 14 STUDY TIP Have a go at writing your own exam questions for the research methods sections covered. Swap these with a friend in class and attempt to answer each other’s questions. Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 82 14/08/23 7:19 PM 5 Research methodology The mean is the arithmetic average. To calculate: 1 Add up the scores to find the sum (Σ). 2 Find N: the number of scores in each set. 3 Divide the sum by the number for each set to give the mean. For example: » Word recall with noise: Σ = 107, n = 10, the mean is 107 divided by 10 = 10.7. » Word recall without noise: Σ = 157, n = 10, the mean is 157 divided by 10 = 15.7. All scores in a data set are taken into account. However, exceptional scores (outliers) can affect the mean. The median is the middle value of a set of scores. To calculate: 1 2 3 4 Put all scores in increasing order. Cross off the lowest score and highest score sequentially. Do this at each end until one score remains. If there are two numbers remaining, add them together and divide by 2 (see Table 5.22). ▼ Table 5.22 Calculating the median Word recall with noise Word recall without noise 14 17 13 17 12 17 12 17 11 16 10 16 10 15 10 14 8 14 7 14 Median = 10.5 Median = 16 The mode is the most frequent score. To calculate: the most occurring score is the mode. Sometimes, there are two modes (bi-modal). In Table 5.21: » The mode for the ‘with noise’ group is 10 (3 scores of 10). » The mode for the ‘without noise’ group is 17 (4 scores of 17). SKILLS BUILDER Explain why the mean would not be an appropriate measure of central tendency for the following data: Time taken to complete memory task (in seconds): 24, 26, 26, 31, 37, 39, 88. [2] Reasoning why some data is more appropriate is a key skill. Review the raw data in the set. Outliers affect the mean as all data in the set are taken into account. Measures of spread Measures of spread show ‘how spread out’ your data is. The range is the difference between the lowest and highest score. Using the word recall example: » Word recall with noise: 14 (highest score) – 7 (lowest score) = range of 7. » Word recall without noise: 17 (highest score) – 14 (lowest score) = range of 3. The standard deviation is the measure of spread of data around the mean. To calculate the standard deviation: 1 The mean is subtracted from each score to see how each deviates from the mean. 2 The remaining calculation identifies the average deviation from the mean. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 83 83 14/08/23 7:19 PM For the word recall data, the standard deviations are: » Word recall with noise: sd = 2.16. » Word recall without noise: sd = 1.33. The ‘without noise’ group has less spread around the mean (sd = 1.33, mean = 15.7) than the ‘with noise’ group (sd = 2.16, mean = 10.7). The larger the score, the more spread out the data. SKILLS BUILDER In the study by Baron-Cohen et al. (eyes test), standard deviations were calculated on the Autism Spectrum Quotient (AQ) scores and are shown in the table below. Standard deviation of AQ scores AS/HFA group IQ matched group 6.0 2.9 Explain what the information in this table indicates about the results of these two groups. [2] An understanding of standard deviation can be shown with an understanding of what the scores show. The higher the value of the standard deviation, the more spread out the scores in the data set (around the mean). In Baron-Cohen’s scores, the AS/HFA group were more variable in their AQ scores than the IQ matched group, with a higher standard deviation (6.0) compared to the IQ matched group (2.9). Data displays Raw data (and measures of central tendency) can be represented graphically. Bar charts Bar charts can be used when data is in categories. Differences in the measures of central tendency between groups can be shown. Using the data from the word recall test, the bar chart shown in Figure 5.2 can be drawn. A bar chart should have a full title and the axes should be fully labelled: » The x-axis (horizontal) names the categories/conditions (independent variable: ‘noise’ and ‘no noise’ groups). » The y-axis (vertical) shows the scale/frequency (dependent variable: ‘the mean number of words correctly recalled out of 20’).

A distribution of scores can be shown (see Figure 5.3). A histogram should have a full title and the axes should be labelled clearly: » The x-axis (horizontal) names the categories of the distribution – in Figure 5.3, this is the time taken (in seconds). » The y-axis (vertical) shows the frequency of occurrences – in this case, the number of students. 14 12 Number of students 10 8 6 4 2 0 <12 12.1–12.5 12.6–13 13.1–13.5 >14 13.5–14 Time taken (in seconds) ▲ Figure 5.3 A histogram to show numbers of students running 100 metres Scatter graphs Scatter graphs are used to show correlations (see page 69).

This will help you to evaluate and discuss both studies as you think about similarities and differences relating to the methodology and how they relate to the issues and debates. ▲ Figure 6.1 Positive symptoms of schizophrenia may include auditory hallucinations, such as hearing voices Schizophrenia is a psychotic disorder. To be diagnosed, a person must have at least two symptoms for at least one month, with one from the first four in Table 6.1. ▼ Table 6.1 Positive and negative symptoms Type Description Symptoms Example Positive Presence of an abnormal symptom Hallucinations: involuntary perceptual experiences in the absence of external stimuli Auditory: hearing one or more voices Experiences of influence, passivity or control: subjective experience that thoughts, feelings and actions are controlled by external forces Thought insertion: for example, aliens implanting ideas into your mind Delusions: fixed beliefs that conflict with reality Persecution: you are being monitored by the police Grandeur: you believe you are superior, such as having special powers Disorganised thinking, speech and movements: thoughts become jumbled, leading to incoherent speech Derailment: ‘train of thought’ diverts onto unrelated topics; speech hard to follow Affective flattening: lack of normal range of emotions When asked about a death in the family, facts may be shared but not how the person feels Avolition: inability to perform goaldirected behaviours Difficulties in everyday functioning, such as cooking a meal Negative Absence of a normal way of thinking, feeling or behaving Asociality: the person is socially withdrawn Avoids social events Relevant research: Aneja et al. (2018) Aim: to investigate the clinical features of very early onset schizophrenia and treatment options. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 91 91 14/08/23 7:19 PM Methodology: six-month analysis of a boy who lived with his grandparents, did not go to school, had aggressive/violent outbursts and required multiple hospital admissions: » primary data = observation and self-report » secondary data = IQ test and medical records. Results: » Positive symptoms: shouting/muttering at unseen others; voices teased him. » Negative symptoms: asociality, difficulties with self-care. » Treated with many drugs and electroconvulsive therapy (see page 97). » Family received psychoeducation and dietary advice. Conclusions: schizophrenia is rare in children. When it does occur, it can be difficult to find an effective combination of drugs. ▼ Table 6.2 Evaluating Aneja et al. (2018) Strengths Weaknesses Validity – the detailed case history provides insight into home and school life. Generalisation – the study included only one 14-year-old boy in Northern India. Mental health is less stigmatised in some cultures, so it may not be representative. Applications – the study provides doctors with treatment options, such as combining atypical antipsychotics. Reliability – the doctors were unable to re-test the boy’s IQ; secondary data (IQ = 90) may be unreliable. SKILLS BUILDER Outline one difference between positive and negative symptoms of schizophrenia. [2] Focus on the defining difference between positive and negative symptoms. You need to compare them. You may use terms like ‘in contrast’ and ‘whereas’. What do the positive symptoms have in common with each other that separate them from the negative symptoms? SKILLS BUILDER Chantel is conducting semi-structured interviews with participants with schizophrenia. Explain one way that Chantel could ensure that the data she collects is valid. [4] Combine your knowledge of research methods with what you have learned in Clinical Psychology. How might positive and negative symptoms affect the way a person with schizophrenia responds in an interview with a researcher? What could the researcher do to help the person to provide detailed and honest answers? The question only requires you to write about one way. Choose your best idea and explore that in detail. ▼ Table 6.3 Evaluating the ICD-11 criteria Strengths Weaknesses Symptoms only need to be present for one month, meaning people can access treatment quickly. As symptoms only need to be present for a month, this could lead to invalid diagnosis, and potentially stigmatisation and marginalisation. Some subtypes of schizophrenia (e.g. paranoid, catatonic) Symptom overlap makes it difficult to reliably diagnose were removed from ICD-11 as diagnoses were often schizophrenia. For example, hallucinations can result unreliable. from depression. Key study: Freeman et al. (2003) Context: » Avatars can trigger emotions (Slater et al., 1999). Freeman wondered how people interpret their behaviour. » He believes research in this area will lead to new ways to diagnose and treat schizophrenia. Aims and hypotheses: » Aim: to investigate the extent to which neutral, non-threatening avatars provoke persecutory thoughts in people with no previous clinical diagnoses. » Hypothesis: people with higher levels of paranoia and emotional distress are more likely to experience persecutory ideation. 92 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 92 14/08/23 7:19 PM 6 Clinical Psychology Research method(s) and design: » Method/design: correlation. » Data collection technique: questionnaires (self-report) and semi-structured interviews.

Procedure: » Participants completed questionnaires to assess mood, anxiety and paranoia. » They were told they would encounter avatars in a VR library and should ‘form an impression’ of them. » After five minutes in the VR library they completed the questionnaires again plus a newly designed measure of situation-specific paranoia. » Participants were interviewed about their VR experience. Interviews were filmed. A clinical psychologist rated levels of persecutory ideation. Controlled variables: same VR experience, avatars behaved in the exact same way; same time in the VR library; same psychologist rating the interviews. Ethics: » No evidence of increased anxiety following the VR experience. » Consent was obtained but to avoid demand characteristics participants were not told the study was about persecutory thoughts. Results: » The mean paranoia score was relatively low. The majority of participants had positive beliefs about the avatars. » 46 per cent agreed at least a little with negative beliefs such as ‘They were talking about me behind my back.’ » VR persecutory ideation was positively correlated with paranoia, interpersonal sensitivity and anxiety. » Qualitative data included: ‘It was nice when they smiled, made me feel welcome’ (positive) and ‘Some were intimidating’ (negative). Conclusion: » Anxiety contributes directly to the development of persecutory ideation. » VR is a promising tool for research and patient assessment and therapy. SKILLS BUILDER Describe the study by Freeman et al. (2003) on virtual reality and persecutory ideation. [6] In your response, always try to explain any specialist terminology that you use – for example, persecutory ideation, paranoia, avatars and virtual reality. ▼ Table 6.4 Evaluating Freeman et al. (2003) Strengths Weaknesses Quantitative data – questionnaire data could be scored objectively and statistics used to draw conclusions. Validity – there were low levels of presence within the virtual library (2.3/6). Participants were only in the library for five minutes. Reliability – standardisation of the VR experience makes the Subjectivity – interviews were rated by one observer, procedure replicable; findings can be tested for reliability. who may have been biased. Issues and debates Individual and situational explanations Freeman et al. (2003) examined how persecutory ideation may be more common in people with higher levels of trait anxiety and/or paranoia. They also looked at how persecutory ideation can be affected by situations, such as being in the VR environment with avatars. Use of children in psychological research Aneja et al. (2018) focused on a 14-year-old child, so parental consent was required. Assent is also important when studying children, especially very vulnerable children, such as the boy in this study.

Sometimes he behaves as though someone is chasing him. He hides behind things and appears very scared. Explain one positive symptom of schizophrenia, with reference to Kasper and his behaviour. [2] 6.2Using examples of research into schizophrenia, explain what is meant by idiographic versus nomothetic. [4] 6.3 From the key study by Freeman et al. (2003), explain one strength of the data from the semi-structured interviews. [2] 6.4Using an example of a case study on schizophrenia, explain one reason why the findings may be described as subjective. [2] 6.1.2 Explanations of schizophrenia Biological explanations of schizophrenia The genetic explanation » Family and twin studies suggest a predisposition to schizophrenia can be inherited. » The concordance rate for monozygotic (MZ) twins = 42 per cent, dizygotic (DZ) twins = 9 per cent (Gottesman and Shields, 1966). » Genome-wide association studies (GWAS) show that certain alleles are more common in schizophrenia, such as those linked to dopamine and GABA. » Deletion of certain genes (e.g. COMT) increases schizophrenia risk. Biochemical explanation: the dopamine hypothesis » Scientists used to believed schizophrenia was caused by excess dopamine. » However, dopamine antagonists were found not to reduce negative symptoms and did not work for some people. » In the 1990s, researchers claimed that: – a lack of dopamine in mesocortical pathways causes negative and cognitive symptoms – excess dopamine in the mesolimbic pathways may result from upregulation. SKILLS BUILDER Jimi works in a laboratory investigating biochemical explanations for mental disorders. His team often use animals in their research. Plan an experiment to help Jimi to investigate the dopamine hypothesis as an explanation of schizophrenia. Your plan must include details about design and a directional or non-directional hypothesis. [10] If you decide to design an animal experiment, make sure you fully understand the relevant ethical guidelines. Section B of Paper 4 ‘Plan a study’ will ask for psychological knowledge upon which your plan is based. Think about this before making your plan. You could talk about the relevant theoretical knowledge as inspiration (development of the dopamine hypothesis or use the studies with rats and apomorphine). SKILLS BUILDER Explain one strength of the dopamine hypothesis. [2] When you are evaluating explanations, think about evidence, applications to everyday life (e.g. the development of effective drug treatments) or the way in which the explanation compares favourably 94 with other explanations (e.g. cognitive). You could also think about whether it is possible to scientifically test the explanation. For example, the dopamine hypothesis can be tested using animal experiments.

Difficulties with mentalising Paranoia, social withdrawal People with schizophrenia have difficulty understanding others’ intentions/mental states. Neutral behaviour is perceived as hostile and social difficulties lead to distress. Counter-evidence bias Delusions Inferences are made in the absence of sufficient evidence. There is a failure to update/modify beliefs in the light of conflicting evidence. ▼ Table 6.6 Evaluating explanations of schizophrenia Explanation of schizophrenia Strengths Weaknesses Biological Evidence – rats injected with drugs that increase dopamine (amphetamines) showed schizophrenic-like symptoms (e.g. strange movements, social withdrawal). Evidence – apomorphine, a dopamine agonist, does not increase symptoms in people with schizophrenia or trigger symptoms in healthy controls. Cognitive Evidence – people with schizophrenia are less likely to recognise recordings of their own voices than healthy controls. Validity – it is impossible to know whether cognitive differences are a cause or an effect of schizophrenia. SKILLS BUILDER Suggest how the cognitive explanation can explain why individuals differ in the development of schizophrenia. This question requires more than a description of the cognitive explanation and may seem rather challenging at first. The question assumes [2] that there are differences between people with schizophrenia. What might those differences be? One person may suffer more from hallucinations and another may suffer more with social withdrawal. These differences may be explained by stating that people demonstrate different types of thinking error. Issues and debates Individual and situational explanations Schizophrenia can result from individual differences in the genome but situational factors also play a role, such as drug-taking and stress (also affected by cultural differences). Nature versus nurture Twin studies (e.g. Gottesman and Shields, 1966) support nature, but findings may be invalid (shared environment fallacy). The cognitive explanation does not explain why some people have faulty thinking, such as through biochemical differences (nature) or modelling family members (nurture). Schizophrenia is likely to result from an interaction of nature and nurture. Environmental (epigenetic) factors cause genes to be expressed or silenced. Diathesis-stress model: some people are genetically predisposed but only develop symptoms if they encounter situational stressors (nurture), such as traumatic life events, discrimination or poverty. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 95 95 14/08/23 7:19 PM SKILLS BUILDER Evaluate the biochemical explanation (the dopamine hypothesis) of schizophrenia, including a discussion of reductionism versus holism. [10] You may want to address the named issue/debate first, as it is an important part of your answer. Which do you think is more reductionist – the biological or cognitive explanation? Why? Our ‘biology’ is affected by lifestyle choices, such as mindfulness, sleep, exercise and diet. Thinking in more depth about the interaction of individual and situational factors with regard to nature and biology will help you to realise that biological explanations may not be as reductionist as first thought. NOW TEST YOURSELF 6.5Noah is researching his family tree. He is surprised to discover that more than half of the relatives he has been investigating showed symptoms of schizophrenia at some point in their lives. Using your knowledge of biological explanations of schizophrenia, suggest one reason why Noah should not be surprised by this discovery. [2] 6.6 Explain two weaknesses of the cognitive explanation of schizophrenia. [4] 6.7 Suggest one reason why a researcher investigating the dopamine hypothesis as an explanation of schizophrenia might use a non-directional hypothesis. [2] 6.8 Suggest one application of the cognitive explanation of schizophrenia. [2] 6.1.3 Treatment and management of schizophrenia Biological treatments Biochemical » Antipsychotic drugs (see Table 6.7) can be given orally or transdermally (through the skin). » Regular check-ups help to monitor dosages, symptoms and side effects. » The order in which drugs are prescribed is usually based on evidence-based protocols. » Treatment-resistant patients may be given mood stabilising drugs and electroconvulsive therapy (ECT). ▼ Table 6.7 Biochemical treatments of schizophrenia Type of antipsychotic Mode of action Effects Typical (e.g. chlorpromazine) Blocks dopamine receptors without activating them; decreases dopaminergic signalling (dopamine antagonists) Reduces positive symptoms for about 60 per cent of people; negative symptoms usually remain Atypical (e.g. clozapine) Blocks dopamine and serotonin receptors Decreases tardive dyskinesia; treats positive and negative symptoms; can lead to agranulocytosis SKILLS BUILDER Many people with schizophrenia do not like taking antipsychotics and this can lead to non-compliance. Plan a study using a questionnaire to find the main reasons why people with schizophrenia fail to take their medication. Your plan must include details about: » question format » sampling technique. [10] Section B of Paper 4 will always ask you to plan a study for one of your options. The mark allocation 96 will always be 10 for part a and 8 for part b. What is less predictable are the questions in part c. Always read these before starting your plan. Reasons for the choices you have made, and the strengths and weaknesses of these choices, are often required. Remember, questions starting with ‘Why’ are always open, such as ‘Why do you dislike your daily medication?’. Questions with rating scales are always closed, such as ‘How much are you affected by side effects? 1 (not at all) to 10 (severely affected)’. Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 96 14/08/23 7:19 PM 6 Clinical Psychology Electroconvulsive therapy » ECT is an addition, not an alternative, to medication. » It is believed to trigger gene expression and improve neural connectivity (Singh and Kar, 2017). » 70–150 V electrical pulses are delivered to the brain via electrodes. » This triggers brief, controlled seizures. » Patients typically receive muscle relaxants and general anaesthetic. » Two to three sessions a week for one month, and maintenance ‘doses’ for up to a year. SKILLS BUILDER Michaela is starting ECT as a treatment for schizophrenia. Suggest one reason that Michaela’s doctor might have referred her for ECT. [2] You need to understand what is meant by ECT to answer this question. Think about why a doctor would refer a patient for ECT rather than prescribing medication or cognitive-behavioural therapy. For example, ECT is only used when other treatments have failed. Other treatments may have failed because Michaela suffered bad side effects and became non-compliant, or she may have struggled to develop a strong rapport in cognitivebehavioural therapy (CBT), meaning the therapy was ineffective for her. SKILLS BUILDER Evaluate biological treatments for schizophrenia, including a discussion of generalisations from findings. [10] Think about evidence to support efficacy from RCTs, longitudinal studies and meta-analyses (see pages 60 and 71 to review these methods). Each method has strengths and weaknesses that you could discuss. You might also consider practical issues regarding the use of these treatments in clinical settings, as well as drawing comparisons with psychological treatments such as CBT. The named issue here is about generalisation from findings. Do you think drug treatments would be as effective in the population as they seem to be in research studies? Why might they be less effective in the community? Think about the samples used in studies. Tip: they are often WEIRD (Western, Educated, Industrialised, Rich and Democratic). Psychological treatment and management Cognitive-behavioural therapy » Therapists develop supportive therapeutic alliances with clients. » Links between events, sensations, thoughts and feelings are discussed. » Clients are helped to identify early warning signs of an imminent episode. Stress management techniques and coping skills can then be used to prevent deterioration. » Techniques include: – keeping symptom diaries – challenging delusions and reflecting on whether they are supported by evidence – thought linkage; a technique to address disorganised thinking – paced activity scheduling to reduce fatigue and stress. » Psychoeducation is provided for the person and their family, such as informing them about the links between schizophrenia and stress. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 97 97 14/08/23 7:19 PM Relevant research: Sensky et al. (2000) Aim: to compare the efficacy of one-to-one CBT and a befriending intervention for people with schizophrenia. Methodology: » Adult with schizophrenia received CBT or befriending (e.g. talking about hobbies); average of 19 sessions over 9 months. » Symptoms were assessed before and after treatment and nine months later. Results: both groups showed a reduction in post-treatment symptoms. Only the CBT group showed continued improvement at the nine-month follow-up. Conclusions: in the long term, CBT was more effective than befriending. ▼ Table 6.8 Evaluating Sensky et al. (2000) Strengths Weaknesses Validity – including the befriending control group meant the researchers could conclude that improvement in the CBT group was not simply due to time spent with an interested companion. Validity – it was unclear whether CBT was effective on its own, as all clients were also using medication. Generalisations – the sample included clients from five clinical services from different parts of the UK. Longitudinal design – 15 people dropped out; findings may only be generalisable to people who are fully committed and form a strong rapport with the therapist. SKILLS BUILDER Explain two ethical guidelines that should be followed when conducting research into the effectiveness of treatments for schizophrenia. [4] Note down all the ethical guidelines you can think of (think DDRIPP: Deception, Debriefing, Right to withdraw, Informed consent, Protection from harm, Privacy/confidentiality). Now, select two that are particularly relevant to treating schizophrenia – for example, how data could be stored confidentially and why this is important; the importance of informed consent in studies involving placebos. ▼ Table 6.9 Evaluating treatments for schizophrenia Biochemical ECT Cognitivebehavioural therapy 98 Strengths Weaknesses Evidence – 94 per cent of antipsychotics tested in a meta-analysis of 56 RCTs had lower relapse rates than placebos. Evidence – 22 per cent of antipsychotics performed no better than the placebos. Applications – drug treatments help people to live in the community and reduce hospitalisations. Side effects such as dizziness, nausea and excessive weight gain can lead to noncompliance and may be fatal. Evidence – 50 per cent showed a reduction in symptoms of 40 per cent or more when combining clozapine and ECT. Validity – double-blind experiments using sham ECT show no significant difference between experimental and control groups. Applications – rapid improvement has been seen for some people after just one session. Ethics – many countries deliver unmodified ECT (i.e. without the safeguards of muscle relaxant and anaesthetic). Ethical – clients take ownership of their recovery; they are actively involved, unlike drugs or ECT, which are more passive. Applications – efficacy relies on the therapeutic alliance and homework. Patients who lack commitment, communication and organisational skills may benefit less. Supporting evidence – Sensky et al. (2000) (see below). Applications – more expensive and time-consuming than drug treatments as more appointments are required.

Numerical data from rating scales means statistics can be used to draw generalisable conclusions. Idiographic studies, such as interviews and case studies, may help researchers to understand the role of social support and the therapeutic alliance in the efficacy of treatments. Cultural differences ECT is controversial in many cultures (e.g. Slovenia), but in China, more than 50 per cent of people with schizophrenia receive ECT (Wang et al., 2018a). China is a high power distance index (PDI) culture – clients may exaggerate the efficacy of ECT due to the unequal relationship between patients and health professionals/researchers. NOW TEST YOURSELF 6.9 Lockie has recently been diagnosed with schizophrenia. He has been prescribed an atypical antipsychotic. Suggest one reason Lockie’s doctor might have decided to prescribe an atypical antipsychotic. [2] 6.10 Lockie’s doctor also refers him to a cognitive-behavioural therapist. Suggest two ways Lockie and his therapist might [4] try to reduce his symptoms. 6.11 With reference to relevant research, explain one strength of experiments as a way of investigating the effectiveness of treatments for schizophrenia. [4] 6.12Outline one weakness of longitudinal studies as a way of investigating the effectiveness of [2] treatments for schizophrenia. 6.2 Mood (affective) disorders 6.2.1 Diagnostic criteria (ICD-11) for mood (affective) disorders Mood is on a continuum from mania/euphoria to severe depression. Typically, mood fluctuates around the centre. If very high or very low mood dominates for an extended period and impairs daily functioning, a mood disorder may be diagnosed. STUDY TIP When revising the Beck Depression Inventory, you could download a copy from the internet (see https://tinyurl.com/j9ed7rwb). Choose a few of the items and create a mnemonic to help you remember them. For example, the first three items are sadness, pessimism and past failure; you could remember these as SPF: ‘study prominent facts’. ▼ Table 6.10 ICD-11 definitions of mood disorders (World Health Organization, 2018) Symptoms Duration Depressive disorder (unipolar) Depressed mood; reduced interest in activities; difficulty Most of the day, concentrating; feeling worthless; excessive or inappropriate guilt; nearly every day, for hopelessness; recurring thoughts of death/suicide; changes in appetite at least two weeks or sleep; feeling agitated; slow movements; low energy; fatigue Bipolar disorders Alternating depressive and manic episodes; manic episodes include euphoria, irritability, grandiosity, highly active, subjective sense of increased energy, rapid speech, rapidly changing thoughts/ideas, decreased need for sleep, easily distracted, impulsive and reckless Mania for at least one week; depressive and manic symptoms may be experienced within the same week or even day (mixed episodes) Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 99 99 14/08/23 7:19 PM SKILLS BUILDER [2] Describe one symptom of unipolar disorder. ‘Describe’ means to give a detailed account. Avoid simply identifying or stating a symptom. Write a full sentence that gives detail about what it might be like to experience this symptom. For example, ‘Difficulty concentrating means that, although you are focusing on a task, your mind might wander onto thoughts about other things that you have to do, or you might be distracted by sights and sounds around you.’ You could also give an example, such as how the symptoms might affect a person at school or work. Measuring depression: Beck Depression Inventory » The Beck Depression Inventory (BDI) is a psychometric test (see page 100) that measures symptom severity using 21 items scored from 0–3. » It considers symptoms from the last two weeks. » It is designed to be used by qualified health professionals (not self-diagnosis). ▼ Table 6.11 Evaluating the diagnosis and measurement of mood disorders Strengths Weaknesses ICD-11 diagnosis of mood disorders Reliability – inter-rater reliability is high (84 per cent) for bipolar disorder and recurrent depressive disorder using ICD-11 (Reed et al., 2018). Reliability – ICD-11 is less reliable when diagnosing dysthymia (45 per cent) (Reed et al., 2018). The BDI Validity – there is a positive correlation between the BDI and the Hamilton Psychiatric Rating Scale for Depression. Self-report – social desirability bias may reduce validity; symptoms may be underreported or exaggerated. Practical – provides quick and precise data; good for assessing treatment efficacy in research and clinical practice. Quantitative data – ignores contextual information (e.g. why a person has depressive symptoms). SKILLS BUILDER Explain one strength of the Beck Depression Inventory with reference to quantitative data. [2] Read the question carefully. You are not being asked for a strength of quantitative data or just any strength of the BDI. Think about the strengths of quantitative data and how these strengthen the BDI as a measure of the severity of depressive symptoms. Think about what the BDI does: it categorises people’s symptoms as mild, moderate and severe. Why is this a good thing and why is using numerical data helpful in achieving this goal? SKILLS BUILDER a Describe the Beck Depression Inventory. b Evaluate the Beck Depression Inventory, including a discussion of psychometrics. Although this question seems unlikely, it is still a legitimate Paper 3 extended response question. It is a good one to practise as it will push you to really elaborate your points. Your evaluation is likely to include two well-elaborated strengths 100 [6] [10] and two weaknesses. Use the points in Table 6.11 to create full PEEL paragraphs (state your point, explain evidence, link back to your argument, e.g. ‘This is important because … ‘). When discussing psychometrics (see page 65), you could give an alternative, such as the trauma-informed approach, which uses a psychological formulation and is therefore more idiographic.

Individual versus situational explanations ▲ Figure 6.2 Somatisation ICD-11 views mood disorders as an individual difference in the way a person refers to the idea that people with depression from low-tothinks, feels and behaves. Alternatives such as the trauma-informed approach middle-income cultures often (Johnstone, 2018) focus more on situational factors, including what has happened report aches and pains rather to the person that has led them to feel like this. than emptiness or apathy SKILLS BUILDER When answering question 6.16 below, think about general features such as aim(s), procedure, sample/ sampling technique and ethical considerations, as well as ensuring that the findings will be valid and reliable. Also think about the type(s) of data Sissi might collect and the descriptive statistics she should use to analyse her data. Part b of the question asks about a piece of psychological knowledge on which your plan is based. This could be the ICD-11 criteria for unipolar depression or the BDI, which you could use as your measure of severity of symptoms. The required method is correlation, so you will need two variables, each measured using quantitative data. Remember, if you use a rating scale, show how the responses will be scored, e.g. ‘How often do you exercise? 1 (never) to 7 (at least once a day)’. NOW TEST YOURSELF 6.13 Kari is a mother and a secondary school teacher. She has been diagnosed with unipolar depression. Explain two ways in which her diagnosis may affect her functioning in everyday life. [4] 6.14 Suggest one way to improve the validity of the Beck Depression Inventory. [2] 6.15 Explain what is meant by a psychometric test, with reference to the Beck Depression Inventory. [2] 6.16 Sissi is planning a correlation in which she will investigate whether people with unhealthy lifestyles have more severe depressive symptoms. a Plan a correlational study that will allow Sissi to investigate this topic. Your plan must include details about: – the measurement of the two covariables – a suitable directional hypothesis. [10] b For one piece of psychological knowledge on which your plan is based: i Describe this psychological knowledge. [4] ii Explain how you used two features of this psychological knowledge to plan your correlation. [4] 6.2.2 Explanations of mood (affective) disorders: depressive disorder (unipolar) Biological explanations Biochemical » Depression is caused by low levels of noradrenaline. » Serotonin regulates noradrenaline. » A serotonin imbalance could cause noradrenaline levels to decrease, leading to depression, or increase, leading to mania. » A serotonin deficiency may result from: – a low tryptophan diet – a high level of cortisol (stress hormone) Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 101 101 14/08/23 7:19 PM – overly sensitive, post-synaptic receptor sites – high levels of monoamine oxydase (an enzyme) – abnormalities of the presynaptic reuptake pumps (transporter molecules). Genetic » Vulnerability is inherited. » Specific alleles of candidate genes linked to serotonin may increase the risk. » For example, short alleles of the 5-HTT gene appear to increase depression risk when facing stressful life events compared with long alleles (Caspi et al., 2003). Key study: Oruč et al. (1997) Context: depression research has focused on serotonin-specific genes. For example: » 5-HTR2c: codes for postsynaptic receptors; linked to appetite, which is often disrupted in depression » 5-HTT: codes for presynaptic transporter molecules; short alleles linked to depression (Caspi et al., 2003). Aim: to determine whether specific alleles of the 5-HTR2c and 5-HTT genes are more frequent in people with bipolar disorder than controls. Research method(s) and design: » Method/design: correlation. » Data collection technique: interviews and blood tests. Co-variables: whether a person has bipolar disorder or not; whether the person is carrying the 5-HTR2c alleles Cys (C) or Ser (S) and the 5-HTT alleles 1 or 2. Sample: opportunity sample of 82 adults from Croatia, 42 with bipolar disorder. Procedure: » Interviews and medical records were used to diagnose bipolar disorder. » Blood samples were used to determine 5-HTR2c and 5-HTT alleles. Controlled variables: bipolar diagnoses checked; control group matched for age/sex. Ethics: » Confidentiality: medical records had to be kept secure. » Informed consent: participants needed to understand why their blood was being tested and why their medical records were being accessed. Results: » In the bipolar group, 38 per cent had at least one first-degree relative with a mood disorder, compared with 0 per cent in the control group. » The S and 1 alleles were more common in diagnosed females than healthy female controls. Conclusion: S and 1 variants of the 5-HTR2c and 5-HTT genes may increase depression risk in females. SKILLS BUILDER Cordelia is worried about developing unipolar depression since she found out that both her biological parents have this disorder. Explain why Cordelia might be worried, with reference to one or more biological explanations.[4] This question gives you the option to include one or more explanations. Bullet-point two explanations in the margin before you start (e.g. genetic and biochemical). Write down a few key words associated with each explanation before you start writing your answer (e.g. alleles, inherit, 102 vulnerable). Now your memory is refreshed, start your answer. For example, Cordelia might be worried because she thinks she has inherited specific gene variants (alleles) from her parents that could increase her vulnerability to depression.’ You could also explain why this is a worry. Improve your answer by referencing specific knowledge, like the role of the S allele of the 5-HTR2c gene, which codes for serotonin transporter molecules on the presynaptic cell.

(1997) Strengths Weaknesses Validity – two experienced psychiatrists checked whether participants had bipolar or not using the Croatian version of a structured interview schedule. Generalisation – the sample size was small; only three people (all male) had the SS genotype of the 5-HTR2c gene. Reliability – other studies had the same results for both the 5-HTR2c and 5-HTT genes (Gutiérrez et al., 1996; Kelsoe et al., 1996). Validity – cause and effect cannot be be established as the variables were naturally occurring and the groups were only matched on age and sex. SKILLS BUILDER Explain one strength of the key study by Oruč et al. (1997) with reference to reliability. [2] Reliability refers to the consistency of an instrument used to make measurements in a psychological study. In this study, S or C alleles of the 5-HTR2c gene were determined with a blood test. This type of data requires little interpretation (objective); two or more researchers are likely to code the data in the same way, so the measurements are reliable. Another way of answering would be to talk about the reliability of bipolar diagnoses. Psychological explanations Beck’s cognitive theory of depression » Depressive symptoms are caused by negative thoughts stemming from dysfunctional core beliefs (Beck, 1962). » The more negative thoughts a person has, the worse their symptoms. » Depressed people hold negative beliefs about the self, the world and the future (the negative cognitive triad). » These beliefs develop in childhood due to criticism, rejection, neglect, abuse, bullying, experiences of loss and overprotective parenting. » Confirmation bias means depressed people focus on information that supports negative beliefs and ignore conflicting evidence. » Other faulty thinking strategies include catastrophising and personalising. Learned helplessness/attributional style » Depression is a learned response to a negative experience. » If a neutral stimulus becomes associated with an unavoidable negative stimulus, people may fail to initiate coping strategies when faced with a similar situation in the future. » Apparent lack of control over the environment leads to hopelessness, passive acceptance and overgeneralisation to other situations. » Depressive attributional style (pessimism) is a negative bias in the way that people process information about success and failure (see Table 6.13). ▼ Table 6.13 Psychological explanation of depression: depressive attributional style Pessimism Internal: failures are blamed on dispositional factors. Global: failure is generalised to many areas of life. Stable: expectation of continued failure. Optimism External: failures are blamed on situational factors. Specific: failure is seen as specific to one area of life. Unstable: expectation of future success. Relevant research: Seligman et al. (1988) Aim: to replicate previous research showing a positive correlation between depressive attributional style and severity of depressive symptoms. Methodology: » Mood-disordered participants completed the BDI (see page 100) and a questionnaire measuring attributions relating to 12 positive and negative events. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 103 103 14/08/23 7:19 PM » They were interviewed to check their diagnosis and reassessed after six months of cognitive therapy. » Post-therapy reassessments were completed at one and twelve months. » Scores were compared with a matched control group. Results: » Depressive attributions for negative events were positively correlated with severity of depressive symptoms before and after therapy, including follow-up assessments. » The greater the decrease in pessimism post-therapy, the greater the improvement in depressive symptoms. » Improvements were impressive and stable over time. » Post-therapy pessimism scores were associated with relapse at 12 months. Conclusions: people with mood disorders tend to make internal, global and stable attributions about negative events, but this tendency can be altered in therapy. ▼ Table 6.14 Evaluating Seligman et al. (1988) Strengths Weaknesses Validity – pessimism was relatively stable in the control group, suggesting that pessimism is a fixed trait rather than a reaction to current circumstances, i.e. a cause of depression and not an effect. Generalisations – the sample included 50 per cent more females than males, who may not represent all men with depression. Validity – triangulation (BDI and interviews) increased the validity of measures of symptom severity. Attrition – 33 per cent dropped out before the final follow-up. The remaining participants may not be representative of all people with depression (e.g. they may have had less severe symptoms). ▼ Table 6.15 Evaluating explanations for mood disorders Approach Explanation Strengths Weaknesses Biological Biochemical Evidence – reducing tryptophan through diet increased depressive symptoms in people with depression. Evidence – low serotonin may be an effect of depression, not a cause. Serotonin decreases in monkeys whose social status changes from dominant to submissive. Applications – enabled the development of drug treatments, helping people improve daily functioning, e.g. working, caring for family. Deterministic – suggests that everyone responds in the same way to reduced serotonin and noradrenaline. Supporting evidence – concordance rate for MZ twin pairs = 38 per cent, DZ = 14 per cent. Validity – the shared environment fallacy reduces the validity of the findings of MZ/DZ twin studies (see page 94). Applications – a better understanding of the genes associated with different types of depression could mean treatments can be tailored to each patient’s individual genome (pharmacogenomics). Reliability – genome-wide association studies (GWAS) have failed to identify consistent patterns of genes associated with depression. Beck’s cognitive theory Scientific: Experiments can be designed to test hypotheses derived from the theory, e.g. whether depressed people use confirmation bias more than non-depressed people. Overly deterministic: Some people may exercise their freewill and regain control of automatic thinking through therapy or coaching. Learned helplessness/ attributional style Evidence: Seligman et al. (1988) (see above) Bidirectional ambiguity: Depressive attributional style may be an effect rather than a cause of depression.

For example, Kendler et al. (2018) found an increased risk for depression in adoptive children where the adoptive parent had depression (supporting nurture). However, Mendlewicz and Rainer (1977) found that 31 per cent of biological parents of adopted children with bipolar disorder also had a mood disorder, compared with only 12 per cent of adoptive parents (supporting nature). Oruč et al. (1997) support nature, whereas Seligman et al. (1988) support nurture. Reductionism versus holism The study by Oruč et al. (1997) is an example of biological reductionism as it examines the role of single genes and fails to acknowledge epigenetic factors, which affect gene expression. Studies that investigate the diathesis-stress model provide a more holistic account as they explore the ways in which biological and social factors interact. Determinism versus freewill Psychological explanations may be seen as overly deterministic. Some people may exercise freewill and regain control of automatic thinking through therapy or coaching. SKILLS BUILDER When answering ‘Plan a study’ questions such as 6.20 below, think about the key studies you have revised for the topic area named in the question, such as Oruč et al. (1997). You could use a similar design as the basis of your study. How would you recruit a representative sample using random sampling, for example? Would this be practical? Part b of question 6.20 asks you to justify your choice of hypothesis. As Oruč et al. (1997) did not find significant results overall (only the results for women were significant) but others have, which type of hypothesis would be most sensible, directional or non-directional? NOW TEST YOURSELF 6.17 Destiny is very tearful and finds it difficult to concentrate at work. Her doctor explains that this may be due to a serotonin imbalance. Outline the biochemical explanation of unipolar depression with reference to Destiny’s symptoms. [2] 6.18 Explain one strength of the cognitive explanation of depression. [2] 6.19 From the key study by Oruč et al. (1997), explain one advantage of using blood tests in this study. [2] 6.20 aPlan an experiment to investigate the genetic explanation of unipolar depression. Your plan must include details about: – sampling technique – a directional or non-directional hypothesis. [10] b Explain one reason for your choice of a directional or non-directional hypothesis.

SKILLS BUILDER Explain one weakness of cognitive restructuring as a treatment for mood disorders. [2] Think about how psychologists conduct studies to support therapies (e.g. longitudinal studies). A classic weakness of longitudinal research is that generalisability can be affected by attrition. Think about why attrition might be high for people undergoing cognitive therapy. Now you should be able to state that the evidence base supporting the use of cognitive therapy may be flawed. Elaborate carefully and link specifically to cognitive therapy to get both marks. Ellis’s rational emotive behaviour therapy (REBT) » Therapy should focus on interpretations of events/situations, as opposed to the events themselves. » REBT focuses on present solutions, not past events. » Therapists work collaboratively to help clients to challenge self-defeating thoughts and reduce negative emotions and behaviours. » Musturbation is tackled through disputing. » The end goal is for clients to accept themselves, other people and their life, including all good and bad points. 106 SKILLS BUILDER Compare one biological and one psychological treatment for one mood disorder. [4] ‘Compare’ means to identify/comment on similarities and/ or differences. You could write about two similarities, two differences or one of each. For example, non-compliance can be a problem for both biological and psychological treatments. This could be your first similarity and then you could elaborate your point by showing why people stop taking their medications or stop attending therapy. Your second point could show how the treatments are similar or different with regard to one of the issues and debates.

Side effects – side effects can be debilitating; some of the most effective drugs have the worst compliance rates. Practical – biological treatments are a cheap and low commitment solution for many people, unlike cognitive therapy, which is timeconsuming and costly. Limited effects – differences between drugs and placebos may be statistically significant but may not lead to a great deal of change in everyday life. Remission rate – 75 per cent of people who received drug treatment plus cognitive therapy were symptom-free after two years, compared with 25 per cent using drugs alone (Fava et al., 1998). Non-compliance – some people are not sufficiently organised/self-motivated to carry out weekly homework exercises. No side effects – compliance rates may be higher than drug treatments. Accessibility – cognitive therapy requires welltrained therapists; location and financial cost may mean this is not an option for many people. SKILLS BUILDER Joel is carrying out research into patient experiences regarding the treatment of mood disorders. Plan a study using semi-structured interviews to help Joel to investigate this topic. Remember to think about the aim(s), procedure, [10] sampling and ethical considerations. Think of some open and closed questions Joel could ask and then think about how he would analyse the answers. Would the interviews be better face to face, online or over the phone? Think about how he could ensure people answer the questions honestly, to increase validity, and how he can check that his data is reliable. Issues and debates Individual versus situational explanations Both biological and psychological treatments focus on changing aspects of the individual – that is, their biochemistry or their beliefs. This sidelines the role of situational factors. Tackling sources of stress in society (e.g. poverty and discrimination) could also improve wellbeing without the need for treatment. Determinism versus free will Free will means people are not at the mercy of negative/irrational beliefs. Instead, they can wilfully choose to control these thoughts through cognitive restructuring and/or REBT. SKILLS BUILDER Evaluate one or more psychological treatments for mood (affective) disorders, including a discussion of reductionism versus holism. [10] If the essay question asks explicitly about biological or psychological treatments, you can always use the other one as part of your evaluation. You could mention that the treatment named in the question is either stronger or weaker than the alternative (e.g. why psychological treatments might be considered better than biological treatments). Often people are prescribed antidepressants and offered cognitive therapy (e.g. restructuring or REBT). This is known as eclectic approach and could lead into a discussion of reductionism versus holism.

She is not enjoying the sessions and wants to stop going. Suggest one reason that Annie may not enjoy REBT. [2] 6.22 Explain one similarity and one difference between Beck’s cognitive restructuring and Ellis’s rational emotive behaviour therapy. [4] 6.23 With reference to studies investigating the effectiveness of treatment, suggest one reason why the findings might not be generalisable. [2] 6.24Outline one individual and one situational factor that might reduce the effectiveness of treatments for mood disorders. [4] 6.3 Impulse control disorders 6.3.1 Diagnostic criteria (ICD-11) Impulse control disorders (ICDs) involve: » a build-up of tension » recurrent, irresistible urges to carry out specific behaviours » short-lived euphoria/relief when the behaviour is performed » distress and dysfunction due to shame/guilt. ▼ Table 6.18 Impulse control disorders Type Urge/compulsion Prevalence Age/gender differences Kleptomania Stealing unwanted/unnecessary 0.6 per cent of general items population Can develop at any age; more common in women Pyromania Fascination with fire, firestarting paraphernalia and the fire service Relatively young age of onset; severity increases over time Gambling disorder Impaired control over 4 per cent (in the US; Black gambling; prioritising gambling and Shaw, 2019) over other daily activities Between 3 and 6 per cent of psychiatric inpatients (Burton et al., 2012) Average age of onset is mid-30s but can be 8–80; earlier onset in men than women (Black et al., 2015) SKILLS BUILDER Omid works in a casino. He wonders whether any of his customers have a gambling disorder. Explain one difference Omid might observe between people with and without a gambling disorder. [2] Your answer needs to link a characteristic of gambling disorder to something Omid might observe in his customers. For example, ‘Omid might see people with gambling disorders coming to the casino when he knows they should be at work (prioritising gambling over other daily activities), whereas other people only visit the casino after working hours.’ Notice how the example includes ‘whereas’, showing that the answer includes both people with and without gambling disorder. Measuring impulse control disorders The Kleptomania Symptom Assessment Scale » The Kleptomania Symptom Assessment Scale (K-SAS) is an 11-item self-report scale, scored from 0 to 4. » The respondent considers thoughts, feelings and actions in the past week. » More than 31 out of 44 is considered severe; more than 21 is considered moderate. » Sample item: ‘If you had urges to steal during the past week, on average, how strong were your urges? None (0) Mild (1) Moderate (2) Severe (3) Extreme (4)’. 108 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 108 14/08/23 7:19 PM 6 Clinical Psychology ▼ Table 6.19 Evaluating the K-SAS Strengths Weaknesses Practical – the K-SAS only takes ten minutes; no training is required to administer/score. Self-report – may not be valid unless answered honestly. Quantitative data – no interpretation is necessary. This increases objectivity, leading to less biased diagnosis. Reliability – people may interpret labels on the rating scales differently. For example, one person’s moderate may be another person’s extreme. SKILLS BUILDER Explain one feature of a case study as a way of investigating impulse control disorders. [2] First, bullet-point some ideas about case studies. Refresh your memory on page 66 if you need to. Which of these features would make case studies especially useful for investigating impulse control disorders? Remind yourself of key words associated with ICDs (e.g. tension, urges, euphoria). Choose a feature that you can link to these key words. For example, ‘Case studies take an idiographic approach by collecting detailed information about an individual. This would be useful when studying an ICD like pyromania simply because it is such a rare condition, making it difficult to recruit a larger sample.’ Issues and debates Idiographic versus nomothetic The K-SAS enables a nomothetic approach to kleptomania research. For example, scores can be measured before and after therapy, so conclusions can be generalised regarding treatment efficacy. Case studies (e.g. Glover, 1985; see page 114) are more idiographic; they allow greater understanding of contextual details and the impact of ICDs on people’s lives. SKILLS BUILDER Evaluate the Kleptomania Symptom Assessment Scale (K-SAS), including a discussion of objective and subjective data. [6] This question asks you to think about objective and subjective data. You could discuss K-SAS as being objective as the researchers do not have to use any clinical judgement. They simply add up the ratings given to each item and compare them with the published ranges to determine the severity of the problem. However, K-SAS scores could be seen as subjective as the individual respondent has to interpret each question with reference to their own experiences. This means their answers are specific to them and may not be comparable with other people with the same score. NOW TEST YOURSELF 6.25Outline one similarity and one difference between kleptomania and pyromania. 6.26 aOutline what is meant by idiographic versus nomothetic. b Explain one weakness of taking a nomothetic approach when diagnosing/researching impulse control disorders. 6.27Nevis is planning a study on gambling disorders and cannot decide which type of data to collect. Give one or more reasons why Nevis might decide to use quantitative data rather than qualitative data. 6.28 Explain one strength of the K-SAS as a measure of kleptomania. [4] [2] [2] [4] [2] SKILLS BUILDER Bembe wants to conduct a case study about a client he is working with who has pyromania. Explain how Bembe could collect and analyse his data. [4] What advice would you give Bembe to ensure that his findings are valid and reliable? If you need to, revisit the sections in Chapter 5 on case studies (page 66) validity (page 80) and reliability (page 81). Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 109 109 14/08/23 7:19 PM 6.3.2 Explanations of impulse control disorders Biological explanation: dopamine STUDY TIP » The stimulation of reward centres (e.g. the nucleus accumbens) leads to dopamine signalling and a pleasure rush. » Behaviour followed by pleasure becomes more frequent (see operant conditioning, page 38). » Dopamine is also released before previously rewarded behaviours, leading to excitement and anticipation. » Cues associated with previously rewarded behaviours also lead to dopamine release (see classical conditioning, page 39). Reward deficiency syndrome » Impulse control disorders result from reduced dopamine. » Dopamine deficiency encourages people to seek opportunities to increase dopamine. » Dopamine deficiency may be genetic. SKILLS BUILDER Kesten has pyromania. His doctor thinks this could be related to levels of dopamine in his brain. Explain the dopamine explanation of impulse control disorders with reference to Kesten’s pyromania. [4] Remind yourself of the key features of pyromania, other than fire-starting. Next, think about which brain regions are involved. Are dopamine levels thought to be too high or too low? Why might this be? What effect does carrying out the behaviour have on dopamine? Create diagrams and flow charts to visually represent the explanations in this section. Find images online to illustrate your notes, such as a picture of the brain with the nucleus accumbens labelled, a dopamine molecule or someone starting a fire and a box of matches. Use these to create infographics – for example, on the role of dopamine in impulse control disorders. Simply selecting appropriate images should help to process information more deeply and help you to retain it more effectively. Psychological explanations Behavioural explanation: positive reinforcement » Behaviours that are rewarded will be repeated. » The rush of dopamine that follows stealing, fire-starting and gambling acts as positive reinforcement. » Variable ratio reinforcement (VRR) leads to the highest rates of behaviour, explaining why gambling is so addictive as rewards are unpredictable. » Behaviours learned using VRR are highly resistant to extinction, explaining why repeated losses in gambling have no obvious effect on behaviour. Cognitive explanation: Miller’s feeling-state theory » Tension triggers retrieval of addictive memories (state-dependent memory). » They may also be triggered by people, objects and events (context-dependent memory). » Recall triggers positive feelings (feeling-states) and compulsive behaviour. » The release of tension and resulting euphoria strengthen the feeling-state, increasing the probability of compulsive behaviour even further. » Negative emotions following the behaviour may also trigger the feeling-state, creating a vicious circle. 110 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 110 14/08/23 7:19 PM 6 Clinical Psychology ▼ Table 6.20 Evaluating explanations for impulse control disorders Approach Explanation Strengths Weaknesses Biological Dopamine Supporting evidence – 51 per cent of people with a gambling disorder carry the A1 allele of a gene that codes for dopamine receptors (Comings et al., 1996), compared with only 25 per cent in the general population (Blum et al., 1996). Ignores nurture – rats living in a poor environment were more likely to become addicted to morphine than rats in an enriched environment (Alexander et al., 1981). Applications – helps to explain why dopamine agonists (used to treat Parkinson’s disease) sometimes lead to ICDs as a side effect. This knowledge can help people make informed decisions about treatments. Reductionist – underestimates the role of cognitive and social factors; prenatal tobacco exposure, maternal depression and childhood bullying are all linked to brain development; stress could also increase vulnerability to ICDs. Focus on nurture – explains findings that cannot be explained by nature alone. For example, some people with gambling disorder do not carry the A1 allele. Incomplete explanation – the focus on positive reinforcement may be misplaced; removal of tension is negatively reinforcing. Evidence – supported by Miller’s case study of John, who became addicted to gambling, which he associated with ‘belonging’ and stopped him feeling like ‘a loser’. Reliability – the ‘John’ case study was based on interviews which cannot be replicated. Interpretation of the qualitative data may have been subjective. Psychological Behavioural Cognitive SKILLS BUILDER Evaluate positive reinforcement as an explanation of impulse control disorders, including a discussion of reductionism versus holism. [10] This is a relatively unlikely question as it only focuses on one of the three explanations. However, it is a legitimate question, meaning you need to prepare for this possibility. Think about how psychologists support their explanations. They collect evidence from research studies, each of which has at least one method and data collection technique. How are the effects of positive reinforcement tested (e.g. animal experiments)? Could stealing, fire-starting or gambling be similar? Your discussion of reductionism might focus on the idea that humans have self-awareness and feelings of shame based on social norms and how we should behave. This means a more holistic explanation that takes account of cognitive processes may provide a better explanation. SKILLS BUILDER Compare one biological and one psychological explanation of impulse control disorders. [4] Your comparison point could be about supporting evidence, application and/or issues and debates. For example, the dopamine hypothesis is supported by objective data regarding the percentage of people with ICD carrying the A1 allele, whereas feeling-state theory is supported by subjective evidence, such as Miller’s case study of John. Explain why this is important. For example, objective data is seen as more scientific, strengthening the biological explanation, whereas the feeling-state theory is more difficult to test as the concepts are more abstract. You could look at one comparison point in detail or more than one in less detail. Either way your answer is likely to be around 80 words. Issues and debates Individual and situational explanations The dopamine explanation is an individual explanation. It focuses on differences in people’s dopamine activity, which may be genetic. Situational factors are acknowledged though; cues in the environment may trigger dopamine release, such as lights and sounds on arcade machines. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 111 111 14/08/23 7:19 PM The cognitive explanation is partly an individual explanation. It refers to life events relating to addictive memory and feeling-states, such as John’s father calling him ‘a loser’, but also recognises situational factors, such as environmental cues that trigger feeling-states. Determinism versus free will The idea that A1 allele carriers are predisposed to dopamine deficiency and thus ICDs is determinist. People can and do seek help to overcome their urges and control their own behaviour, demonstrating the role of free will (e.g. Glover 1985 case study; see page 114). The idea of feeling-states is also determinist. It implies that once triggered, the behaviour is unavoidable, yet cognitive-behavioural therapy demonstrates that people are not at the mercy of pre-existing cognitive patterns and biases. People can change the way they think, feel and behave. SKILLS BUILDER Question 6.32 below asks about ‘one piece of psychological knowledge’. This could include theories and/or research studies. There are no named studies for this section, but if you have learned about Olds and Milner (1954), you could use it to evaluate both the dopamine deficiency and the positive reinforcement explanations. Part b asks for ‘features of psychological knowledge’. You could use the fact that Olds and Milner (1954) conducted an animal experiment (high levels of control increase internal validity) and/or the fact that lever pressing is an observable behaviour, making the data more objective. NOW TEST YOURSELF 6.29 Flavia is walking through a department store. She suddenly feels very tense and feels the urge to take items from the make-up counter without paying for them. Explain Flavia’s urge to steal from the store using Miller’s feelingstate theory. [2] 6.30 Explain one similarity and one difference between any two explanations of impulse control disorder. [4] 6.31Outline one application to everyday life of the biological explanation of impulse control disorders. [2] 6.32 Clarisse wants to design an experiment to test explanations of impulse control disorders. Choose one piece of psychological knowledge that Clarisse might use to help design her study. a Describe this psychological knowledge. [4] b Explain two features of this knowledge that may inform her plan. [4] 6.3.3 Treatment and management of impulse control disorders Biological treatments Drug treatments include SSRIs (see page 106), mood stabilisers and topiramate (for kleptomania) and opioid antagonists (see Grant et al., 2008, below). Key study: Grant et al. (2008) Context: » Endorphins bind to opioid receptors, inhibit GABA and allow dopamine to increase. » Opioid antagonists block opioid receptors and reduce euphoria. » Lack of reinforcement (euphoria) leads to extinction of compulsive behaviours. Aims and hypothesis: » Aim: to investigate opiate antagonists as a treatment for gambling disorder. 112 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 112 14/08/23 7:19 PM 6 Clinical Psychology » Hypothesis: opiate antagonists are more effective in reducing gambling disorder in people with a family history of alcoholism, stronger urges and euphoric response to alcohol compared to people who do not fit into these categories. Research method(s) and design: » Method/design: experiment/randomised control trials, independent measures, double-blind. » Data collection technique: structured and semi-structured interviews, questionnaires and psychometric tests. Variables: » Independent variable: random allocation to low, moderate or high dose of nalmefene, naltrexone or placebo. » Dependent variable: difference in Y-BOCS (see page 126) post-treatment. Sample: 284 pathological gamblers; all had gambled in the past two weeks and were outpatients from 15 psychiatric centres. Procedure: » Comorbid diagnoses were identified using a structured interview. » Severity of gambling disorder was investigated using a questionnaire (Y-BOCS). » Measures were taken after the drug trial, which lasted up to 18 weeks. Controlled variables: » Participants had not used these medications before. » None were taking other medications that could interact with the opiate antagonist. Ethics: » Written informed consent was given, including information about alternative treatments. » The fewest number of people possible were put into the placebo group. » Screening took place to eliminate anyone for whom the trial might have been harmful. Results: three factors were associated with positive treatment outcomes: » family history of alcoholism » stronger baseline urges » age (reduced placebo effect in older participants). Conclusion: opiate antagonists have the greatest effect for gamblers who have a family history of alcoholism. The stronger the urges, the higher the probability that these drugs will be effective. Efficacy in younger gamblers may be due to placebo effects. SKILLS BUILDER Suggest one ethical issue Grant et al. (2008) would have considered when conducting the semi-structured interviews about family history of alcoholism. [2] Your first sentence should identify a suitable ethical issue. Bullet-point your ideas first; a mnemonic like DDRIPP will remind you to think about Deception, Debriefing, Right to withdraw, Informed consent, Protection from harm, and Privacy and confidentiality. As the topic is personal and sensitive, it would make sense to talk about confidentiality or right to withdraw. ▼ Table 6.21 Evaluating Grant et al. (2008) Strengths Weaknesses Validity – Y-BOCS was administered by a researcher who was unaware which drug group the person was in or their family history (double-blind). Self-report – participants may not have accurate knowledge regarding family history of alcoholism. Generalisations – participants in the nalmefene group were diverse in terms of age/ethnicity. No follow-up – the long-term efficacy is unknown; family history may predict short-term improvement only. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 113 113 14/08/23 7:19 PM SKILLS BUILDER Marino has a gambling disorder. His doctor has suggested that he tries an opiate antagonist. Marino is wary of taking daily medication. Suggest one or more ways that his doctor could persuade Marino to try a drug treatment. [4] The question asks for ‘one or more ways’. It makes sense to write two sentences about two ideas. Be creative if you need to be. Maybe Marino’s father had alcohol addiction. If so, the drugs are likely to be more effective, according to Grant et al. (2008). Another way to persuade Marino might be to explain that this treatment will require lower commitment than cognitive-behavioural therapy. Psychological (cognitive-behavioural) therapies Covert sensitisation » Covert sensitisation uses classical conditioning to create unpleasant associations with the behaviour the person wishes to stop. » Therapists help clients to visualise disturbing images (unconditioned stimulus) that create unpleasant feelings, such as disgust or shame (unconditioned response). » Images are paired with thoughts about the target behaviour. » Eventually, thinking about the target behaviour elicits negative feelings that override urges to perform the behaviour. Relevant research: Glover (1985) Aim: to evaluate the efficacy of covert sensitisation for kleptomania. Methodology: » Case study: woman with long-term daily kleptomania. » Four therapy sessions: use of muscle relaxants and self-hypnosis to increase vividness of imagery relating to vomiting/people staring. » She practised visualisations several times a day at home. » Follow-up sessions after three, nine and nineteen months. Results: » Urges and stealing reduced. Occasional thefts did not relieve tension. » Daily visualisation exercises were completed several times a day. » The woman became increasingly confident to shop alone. » Nineteen months post-treatment, there were no further relapses. Conclusions: clearly imagining unpleasant scenes helped reduce urges to steal. ▼ Table 6.22 Evaluating Glover (1985) Strength Weakness Cross-case analysis – Kohn and Antonuccio (2002) successfully treated a 39-year-old man who had been stealing from the age of six. Generalisation – the study focused on one 56-year-old woman, so the findings may not represent the wider population. SKILLS BUILDER Evaluate one study of covert sensitisation, including a discussion of generalisations from findings. [10] Typically, essays focus on the treatment rather than focusing on ‘one study’ (unless it is a section containing a key study). However, this is a legitimate question. Take care; it would be easy to mix up the case studies of covert sensitisation and imaginal desensitisation as both studies are about women with impulse control disorder and the names of the therapies are similar. When writing about generalisation, think about whether the treatment would be equally effective for people from different cultural backgrounds (e.g. individualist versus collectivist). Imaginal desensitisation » Therapists interview clients to design personalised guided imagery scripts, including cues that trigger tension/urges and venues where the target behaviour will be performed. 114 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 114 14/08/23 7:19 PM 6 Clinical Psychology » Clients are taught progressive muscle relaxation (PMR) to combat tension. » Scripts have six stages (see Blaszczynski and Nower, 2003, below) separated by brief PMR. » Clients practise guided imagery two to three times a day for five to seven days a week and record their progress. Relevant research: Blaszczynski and Nower (2003) Aim: to provide therapists with instructions on how to conduct imaginal desensitisation. Example: case study of a client with long-term gambling disorder. Mary lost $25,000 in casinos. The therapist created a script based on details about stressors in her life (see Table 6.23). ▼ Table 6.23 Stages in Mary’s guided imagery script 1 Initiating the urge Feeling lonely when others leave work to go home 2 Planning to act on the urge Driving to the casino, feeling excited 3 Arriving at the venue Looking at lights, hearing music at the casino 4 Generating arousal (positive emotions) Finding her favourite dealer 5 Second thoughts, creating sense of boredom and guilt Other gamblers look bored, thoughts turn to previous losses/unpaid bills 6 Negative outcomes/potential alternatives Leaving the casino, feeling good, going to the movies ▼ Table 6.24 Evaluating Blaszczynski and Nower (2003) Strength Weakness Qualitative data – the Mary case study includes a detailed example script to support therapists in creating successful scripts of their own. Lack of evidence – the Mary case study does not report on her progress posttreatment. Therapists may need guidance on expected outcomes. ▼ Table 6.25 Evaluating treatments for impulse control disorders Approach Treatment Strengths Weaknesses Biological Opiate antagonists Evidence – Grant et al. (2008) (see above). Side effects include nausea, vomiting, stomach pain, hypertension and fever. Psychological Covert sensitisation Supporting evidence – Glover (1985), Kohn and Antonuccio (2002) (see above). Subjectivity – the longitudinal aspect of the study means researchers form a relationship with participants; they may become biased, such as seeing improvement in the absence of solid evidence. Comparison to drug treatments – Individual differences – not everyone opiate antagonists have unpleasant can create vivid visual images, such as side effects; therapy may have a people with aphantasia. better compliance rate. Imaginal desensitisation Practical – patient satisfaction is high; only 2–3 sessions are required, so it is cheaper and quicker than covert sensitisation. Individual differences – might be ineffective for people who are undermotivated, poorly organised or who find relaxation difficult. Evidence – 80 per cent of people with gambling disorder found longterm relief following six sessions (Grant et al., 2011). Commitment – drug treatments require less effort than imaginal desensitisation, which requires practice throughout the day.

It ignores sociocultural factors that might differ between people with ICDs. Grant et al. (2008) is more holistic. It considers how the efficacy of drug treatments is affected by a range of factors. Idiographic versus nomothetic Grant et al. (2008) takes a nomothetic approach. The findings should allow practitioners to predict the efficacy of opiate antagonists for their patients. Glover (1985) is idiographic. The aim was to gain insight into the recovery journey of one patient. The study does not suggest that the results are generalisable to other people. SKILLS BUILDER Tia is a therapist. She is working with Alfred, who has gambling disorder. She wants to learn more about the cues that trigger Alfred’s urges. Plan a participant observation to help Tia to investigate gambling disorder. [10] You will need to consider all the general features involved in planning a study but also focus on the specific type of observation named in the question (participant). Think about locations Tia and Alfred might visit and how this could affect her ability to record valid and reliable data. How would the type of observation affect whether the data is quantitative or qualitative? What are the implications of this? NOW TEST YOURSELF 6.33Outline opiate antagonists as a treatment for impulse control disorders.

[4] 6.4 Anxiety and fear-related disorders 6.4.1 Diagnostic criteria (ICD-11) Anxiety disorders are characterised by intense, persistent and unreasonable apprehension and worries about everyday things. A diagnosis is made only if: » symptoms have persisted for almost every day for several months » the person feels distressed by their symptoms » symptoms disrupt everyday life » other conditions have been discounted. ▼ Table 6.26 Anxiety and fear-related disorders Type of anxiety and fear-related disorder Symptoms 116 Generalised anxiety disorder (GAD) Muscle aches and pains, insomnia, restlessness, irritability, poor concentration Agoraphobia Excessive fear/anxiety outside the home, fear of panic attacks in public places Specific phobia (blood-injection-injury) Decreased blood pressure causing fainting (vasovagal syncope) Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 116 14/08/23 7:19 PM 6 Clinical Psychology Measures of anxiety and fear-related disorders The self-report questionnaires shown in Table 6.27 can also be used as structured interview schedules. ▼ Table 6.27 Self-report questionnaires for measuring anxiety and fear-related disorders Generalised Anxiety Disorder Assessment (GAD-7) The Blood Injection Phobia Inventory (BIPI) Number of items Seven items, rated on frequency 18 situations relating to blood and needles, rated on frequency of 27 cognitive, biological and behavioural reactions in each situation; 486 data points per person What is measured? Frequency of symptoms in the last two weeks Situational and anticipatory anxiety Answer format Four-point scale (0–3) Four-point scale (0 = never, to 3 = always) Sample item Trouble relaxing? Not at all (0) Several days (1) More than half the days (2) Nearly every day (4) When I see an injured person after an accident, bleeding in the road or on the television: I feel my face is hot. Scoring 5/21 = mild, 10/21 = moderate (referral needed), 15+ = severe (treatment priority) n/a [6] Essays drawn from the diagnosis section of each disorder may focus on any tests used to help make a diagnosis. You will need to know quite a lot about each test, including the type of questions asked, how they are answered and how the researchers score them. Think about where and by whom these tests might be administered, as well as when and why. The W questions are always helpful to extend your thinking if and when you are running out of things to say. Relevant research: Mas et al. (2010) Aim: to develop a measure of blood phobia symptoms for first-language Spanish speakers. Methodology: » Compared scores from blood phobics and controls on 50 anxiety-related items, rated on four-point Likert-style scales. » Following initial analysis, items were removed that were least helpful in differentiating between blood phobics and controls. » Blood phobics were interviewed and completed the Fear Questionnaire (FQ). Results: » There was a strong positive correlation between the BIPI and the blood subsection of the FQ. » Blood phobics had higher scores on the BIPI than the control group. Conclusions: the BIPI is a valid measure of blood phobia in Spanish speakers. Outline one similarity and one difference between generalised anxiety disorder and agoraphobia. [4] Read the general information above and compile a list of aspects that all anxiety disorders have in common. When writing your similarity, use words like ‘both’ and ‘likewise’. When writing your difference, use words like ‘in contrast’ and ‘whereas’. SKILLS BUILDER SKILLS BUILDER Describe the GAD-7 as a measure of anxiety and fear-related disorders. SKILLS BUILDER Merv’s child needs an injection but he feels sick and light-headed every time he thinks about taking his son to the appointment. Explain one reason Merv might be diagnosed with a blood-injection-injury phobia. [2] What do we know about Merv? Is his anxiety situational or anticipatory? What type of symptoms does he have – physical, affective or cognitive? Which test is used to diagnose blood-injection-injury phobias? You may want to give a reason relating to the extract and then explain how this information relates to the BIPI.

(2010) Strength Weakness Quantitative data – used statistical analysis to eliminate items that were least useful in differentiating between blood phobics and controls. Generalisations – there were three times as many women as men in the blood phobic group; the BIPI may be less effective for men. SKILLS BUILDER Question 6.40 below is a ‘Plan a study’ question. Think about the studies you have learned about in this section. You could use knowledge from Mas et al. (2010) and the BIPI to design a similar study for the GAD-7. Alternatively, you could design a correlational study in which you give participants the GAD-7 and another established measure of anxiety (such as the Fear Questionnaire, also used in Mas et al.). You could collect pairs of scores from each person and plot them on a scatter graph to see whether there is a positive correlation. However you design your study, make sure you word your hypothesis carefully to reflect the design. See page 72 for more on hypotheses. ▼ Table 6.29 Evaluating diagnosis and measurement of anxiety disorders Strengths Weaknesses Generalised Anxiety Strong test-retest reliability.

Methodology: » Self-report data was gathered about phobia origins, age of onset, family history and fainting from people with blood, injection and other phobias (e.g. animals). » While participants watched a surgery video (blood phobics) or had a finger-prick test (injection phobics), researchers recorded: – the time taken to withdraw – self-reported anxiety on a scale of 0–10 – heart rate and blood pressure. Results: » Compared with injection phobics, blood phobics: – had more first-degree relatives with the same phobia – were more fearful of fainting as a phobic response. » Anxiety and time of withdrawal were similar. » There were differences in bodily reactions between the two groups (see Table 6.31). ▼ Table 6.30 Differences between blood and injection phobics when withdrawing from the behavioural tests Blood phobics Injection phobics Heart rate/blood pressure Decrease Increase Fainting More likely Less likely Conclusions: » There are more similarities than differences between blood phobics and injection phobics so blood-injection phobia should remain as one diagnosis. » Although, compared with injection phobia, blood phobia has: – a stronger genetic component – more severe biological reactions. SKILLS BUILDER Professor May is preparing a presentation about the genetic explanation of fear-related disorders. Suggest one way that she could convince her audience that genes contribute to this disorder. [2] This question is simply another way of asking you to explain a strength of the genetic explanation. You just need to use your knowledge in a slightly different way. ‘Suggest’ means to think of an idea. You could state why this is a good suggestion (i.e. how it might help to persuade the audience). You could also suggest that Professor May includes research evidence from Öst (1992), Gratacòs et al. (2001) or Dierssen et al. (2006), and then focus on specific findings. Focus on why your chosen finding might be particularly persuasive. If you chose the Dierssen study, for example, you could emphasise the strengths of animal experiments. ▼ Table 6.31 Evaluating Öst (1992) Strengths Weaknesses Internal validity – data was discounted from seven participants who did not meet criteria for diagnosis when re-assessed. Ecological validity – watching a video of surgery is not the same as encountering blood in real life. Objective data – the behavioural tests did not rely on subjective self-reports in which people have to imagine/ recall encounters with feared stimuli, as have been used in other studies. Validity – primary data about first-degree relatives was not checked to verify whether the diagnosis was accurate. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 119 119 14/08/23 7:19 PM SKILLS BUILDER Explain one validity issue relating to one study investigating the genetic explanation of one fear disorder. [2] You only have to know one study relating to genetic explanations (e.g. Öst, 1992). However, you could be asked a range of different questions about the methodology. Your point could be a strength or a weakness and could relate to operationalisation or control of confounding variables. Remember, though, the question asks you to explain, so state your point giving detail from the study and say why this is an issue. For example, how does it affect the researcher’s ability to draw firm conclusions from the data? Psychological explanation Behavioural: classical conditioning » Phobias are acquired through classical conditioning, where an association may be formed between the two stimuli. » If the neutral stimuli (NS) is encountered again, it may also lead to a fear response (expectancy learning). » The NS is now a conditioned stimulus; fear is a conditioned response (see page 39). Relevant research: Watson and Rayner (1920) Aim: to investigate whether emotional responses can be classically conditioned and whether conditioned fear generalises to other situations. Methodology: » Nine-month-old Albert’s responses to animals (e.g. rat, rabbit) and non-animal stimuli (burning newspaper, building blocks, fur coat, cotton wool) were observed under controlled conditions. » His responses were recorded and filmed. Qualitative data was recorded. » Next, the rat was presented, followed by a loud crash. This was repeated several times and responses were recorded. » Once Albert had been conditioned to fear the rat, he was retested with other animals and white furry stimuli. He was also tested in an alternative room. Results: » Albert was initially fearless when confronted with all stimuli except the loud noise. » After seven pairings of the rat and noise, he began to fear the rat. » He also feared other animals and white furry stimuli but this fear reduced over time. » When tested in another room, Albert still showed some fear towards the rat. Conclusions: fear can be classically conditioned and generalises to other similar stimuli and settings. ▼ Table 6.32 Evaluating Watson and Rayner (1920) Strengths Weaknesses Longitudinal – multiple observations allowed the researchers to record changes in Albert’s fear over time, suggesting fear was learned. Ecological validity – it may have been more difficult to condition Albert if he had been in a familiar setting, such as his own home. Qualitative data – detailed observations about bodily movement, facial expressions and self-soothing provide rich insight. Generalisations – only one infant was studied. Temperamental differences might mean others are more or less easy to condition. Psychodynamic explanation Phobias stem from unconscious, unresolved psychosexual conflicts, such as the Oedipus complex. Freud explains phobias using defence mechanisms. For example, fear is transferred from one situation to another to protect us from awareness of unconscious desires for sex/aggression. 120 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 120 14/08/23 7:19 PM 6 Clinical Psychology Relevant research: Freud (1909) Aim: to describe phobia development and recovery in a young child. Methodology: » Case study of a five-year-old boy with a phobia of white horses. » Qualitative data was gathered in an interview with the child and letters from his father to Freud. The letters contained observations made by the father and things Hans had said. Results: » Widdlers (penises): Hans talked a lot about this body part. His mother told him she would cut it off for touching it. Freud suggested this led to castration anxiety. » Dreams: Freud interpreted a dream about giraffes as symbolising the Oedipus complex. A later dream about a plumber was interpreted as the resolution of this complex, in which Hans identified with his father. » Horse phobia = displacement: Freud believed the horse symbolised the father. Castration anxiety was displaced onto the horse, which Hans thought would bite him. Conclusion: phobias are a way of expressing unconscious fears. They can only be treated through reducing the unconscious fear. STUDY TIP You have to learn two case studies involving children for this section, which are commonly referred to as Little Albert and Little Hans. These could be easily muddled up if you don’t revise them with care. This tip could help you out: Hans starts with H and so does Horse, the animal he was scared of. Albert contains all the letters of the animal he was scared of – a rat. ▼ Table 6.33 Evaluating Freud (1909) Strengths Weaknesses Qualitative data – letters provided insight that could not be gained any other way. Subjective – data was mainly from the father’s perspective. He may have only shared information that he thought would be of interest. Longitudinal – the letters spanned three years. Fear intensity could be monitored over time and conclusions drawn about any changes. Generalisations – Hans was from a wealthy family in Vienna, Austria. The findings may not apply to modern children who spend more time outside the family home. ▼ Table 6.34 Evaluating explanations of anxiety disorders Approach Explanation Strengths Weaknesses Biological Genetic Evidence – 90 per cent of people with fearrelated disorders had a NTRK3 duplication compared with 7 per cent of controls (Gratacòs et al., 2001). Over-expression of NTRK3 increased anxiety/panic in transgenic mice (Dierssen et al., 2006). Validity – twin studies (e.g. Distel et al., 2008) may suffer from shared environment fallacy (see page 95). Evidence – Ost et al. (see below). Reductionist – genes may be silenced or expressed depending on environmental (epigenetic) factors. Evidence – see Watson and Rayner (1920) below. Partial explanation – does not explain why phobic responses are so resistant to extinction; this is better explained by operant conditioning. Applications – led to the development of systematic desensitisation (see page 123), i.e. learned behaviours can be unlearned. Conflicting evidence – cannot explain why certain fears are more easily learned than others, such as snakes versus flowers. Psychological Behavioural: classical conditioning Psychodynamic Evidence – Little Hans case study (Freud, 1909); see below. Case studies – evidence is highly subjective and difficult to generalise. Patients were selective in what they shared with Freud. He interpreted their disclosures according to his theories (researcher bias). Applications - contributed to the development of psychoanalytic therapy, which paved the way for modern talking therapies (e.g. CBT). Unscientific – concepts such as the unconscious are difficult to test; it is not possible to demonstrate that the unconscious does not exist. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 121 121 14/08/23 7:19 PM Issues and debates Determinism versus free will The genetic explanation is deterministic. Certain genes increase vulnerability to anxiety disorders. However, humans have the capacity and choice to make positive lifestyle choices (e.g. diet, exercise) that help to overcome genetic predispositions. Behavioural explanations are also deterministic. Negative experiences mean fears are learned. This ignores cognitive factors that are within conscious control – how we interpret events influences how much they affect us. Nature versus nurture Traditional biological explanations focus on nature but recent discoveries in epigenetics demonstrate the importance of interaction between genetic and environmental factors (nurture). Environmental factors may increase the risk of anxiety disorders but may be positive, such as increasing resilience and reducing risk. Behaviourist explanations do not account for nature. This limits their explanatory power. For example, they cannot explain the results of twin studies. The psychodynamic explanation combines nature and nurture. Drives for sex and aggression are innate. If they’re not expressed, it may increase vulnerability to anxiety. Experiences (nurture) determine the extent to which needs are met and complexes are resolved. SKILLS BUILDER Evaluate one or more psychological explanations of one fear-related disorder, including a discussion of nature versus nurture. [10] This question allows you to focus on just one of the two psychological explanations in this section, or to include both. It may be sensible to include both explanations so you can compare the supporting evidence and the issues and debates. You could also compare psychological and biological explanations so long as you clearly justify why one or the other type of explanation is better. NOW TEST YOURSELF 6.41Ricardo has a fear of goats. His mother believes that it started when the family visited a farm when he was three years old. Using either the psychodynamic or the behavioural explanation, explain how Ricardo’s fear might have developed. [2] 6.42 Compare one study investigating the behavioural explanation of one fear disorder and one study investigating the psychodynamic [4] explanation of your chosen disorder. 6.43Outline what is meant by validity using one study investigating [2] one fear-related disorder. 6.44 Suggest two reasons why a psychologist might choose a case [4] study to investigate explanations of fear-related disorders. SKILLS BUILDER India wants to investigate the development of childhood fears using families from the nursery where she works. Plan a longitudinal study to help India investigate [10] this topic. You will need to consider all the general features involved in planning a study. Focus on the tests/tasks that India might use, how she will score them, how often she will collect data from either the children and/ or their parents and any controls that she needs to consider to ensure her findings are valid. 6.4.3 Treatment and management of anxiety and fear-related disorders Behavioural therapy: systematic desensitisation » Phobic patients are taught to relax using deep muscle relaxation and other techniques. » Clients and therapists develop a fear hierarchy (see Chapter 3, page 41). » Clients are then exposed to the least fear-inducing situation while employing relaxation techniques (reciprocal inhibition). 122 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 122 14/08/23 7:19 PM 6 Clinical Psychology » Gradually, clients work up the hierarchy, moving on when they are able to tolerate each situation without fear. » Exposure may be in vivo or imagined. Psychological therapy Cognitive-behavioural therapy » Therapists assume that fear/anxiety results from cognitive fear structures. New (positive) information is never assimilated into the fear structure due to avoidance of feared situations. » Therapists help people to disconfirm and replace inaccurate fear structures through exposure. Restructuring is usually possible within 20 sessions. » Therapists challenge automatic negative thoughts and ask people to provide evidence for their irrational beliefs, encouraging greater objectivity. » Homework is used to practise skills/strategies between sessions and to report back on experiences. Applied tension » Applied tension (AT) reduces fainting in people with blood-injury-injection phobias (BII). » The client tenses their arm, torso and leg muscles while sitting. » Tension is held for 10–15 seconds, released for 20–30 seconds and repeated five times. SKILLS BUILDER Explain one similarity and one difference between two treatments for fear-related disorders. [4] First, you need to remember the two treatments for fear-related disorders. This may be difficult; there are five disorders in this clinical chapter and many of the treatments are quite similar. This is the only section in which there are no drug treatments. Don’t get confused and start writing about anti-anxiety drugs. The command term is key – explanations require justification. Why is this similarity or difference important? How does it affect the effectiveness or client satisfaction? Key study: Chapman and DeLapp (2013) Context: » CBT is more effective in reducing fear than disgust in people with BII phobias. » Disgust in response to blood is associated with fainting. » Applied tension targets fainting, which is less treatable with CBT alone. Aim: to investigate the efficacy of applied tension as a treatment for BII phobias. Research method(s) and design: » Method/design: case study. » Data collection technique: questionnaires and interview. Variables: anxiety, fear and BII symptoms were measured using psychometric tests (questionnaires). Sample: 42-year-old male with severe BII symptoms (including fainting) for 20 years; avoided doctors and hospitals; family history of BII and experienced childhood bereavements. Procedure: » Baseline data was collected using psychometric tests. » Nine sessions of CBT with AT: – Homework included AT five times a day, graduated exposure tasks, rating anxiety from 0 to 100, and listing thoughts, feelings and behaviours. SKILLS BUILDER Describe how T’s reaction to situations involving blood changed during therapy. [2] You can be asked quite specific questions about the key studies so revise them carefully. You could learn one or two of the specific findings from Table 6.36. Choose one now that stands out to you. Create an image in your mind using the situation and the numbers. For example, a man who is 65 today (he is wearing a big badge with his age on it) is giving blood; his blood type is O. Incorporating the figures into a story (65 and 0) should help you to recall them when you need them. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 123 123 14/08/23 7:19 PM » Early sessions included psychoeducation and creating a ten-item fear hierarchy. Items were rated on the Subjective Units of Discomfort Scale (SUDS). » Graduated exposure exercises at home and in sessions: – watching blood tests on YouTube – finger-prick blood test – observing people donating blood – booking and having a blood test. » Further data was collected at four, ten and twelve months after treatment. Controlled variables: the same psychometric tests were taken before and after treatment. Ethics: » Anonymity was maintained through the use of initial (‘T’). » T progressed through the hierarchy at his own pace, protecting him from harm. Results: ▼ Table 6.35 Results from Chapman and DeLapp (2013) Session Situation Initial SUDS Reduced SUDS 6 Watching blood test videos 35 20 7 Having a finger-prick test 45 20 8 Watching blood donations 65 0 9 Having a blood test 40 0 At the 12-month follow-up, all test scores were significantly reduced. For example, on the Blood-Injection Symptom Scale, T said he experienced all 17 sensations before treatment but only 4 out of 17 after treatment. Conclusion: CBT with AT is an effective treatment for BII phobias. ▼ Table 6.36 Evaluating Chapman and DeLapp (2013) Strengths Weaknesses Quantitative data – SUDS scores collected before, during and after treatment allowed changes to be monitored within and between sessions. Self-reports – SUDS scores were given orally so may be subject to social desirability bias and demand characteristics; validity may be reduced. Applications – a detailed case history about the client helps other therapists to determine whether AT might be helpful for similar clients. Validity – with no control group, it is impossible to know how much BII symptoms might reduce in the absence of treatment or through CBT alone. SKILLS BUILDER Describe applied tension as a treatment for blood-injectioninjury phobia. [6] Extended response questions are often centred around key studies. In this question, your knowledge will be derived almost entirely from Chapman and DeLapp (2013). Be mindful not to just revise the technique but also how it disrupts the diphasic response and prevents fainting. You could also include how the technique is combined with graduated exposure tasks and SUDS ratings. ▼ Table 6.37 Evaluating treatments for anxiety disorders Strengths Weaknesses Supporting evidence – cats were taught to fear cages using shocks and then gradually deconditioned using food (Wolpe, 1976). Time-consuming – gradual progress over several sessions may be too expensive for some people. Flooding therapy has no hierarchy and is as effective as systematic desensitisation. Applications – has been used to treat phobias, including agoraphobia (Lipsedge et al., 1973), as well as specific phobias, such as spiders. Individual differences – some people find it difficult to relax without anti-anxiety medications. Psychological therapy: Cognitive- behavioural therapy Efficacy – Can be more effective than behavioural techniques alone, especially when treating disgust-based phobias (see Saavedra and Silverman, pages 38–42). Efficacy – May not be effective for treating BII phobia which may require applied tension as well to reduce fainting (see Chapman and DeLapp (2013) above). Applied tension (for bloodinjection-injury phobia) Supporting evidence: See Chapman and DeLapp (2013) above. Methodology – See weaknesses of Chapman and DeLapp (2013) above.

It provides detailed insight into one client. The therapists wrote up the study to raise awareness of the potential benefits of AT to other clients, not to make generalisations to all BII phobics and all CBT/AT therapists. SKILLS BUILDER Question 6.48 below is a ‘Plan a study’ question. In this section, you have learned about the key study by Chapman and DeLapp (2013). You may be able to borrow ideas from this study to inspire your own. You are asked to include details about question formats and scoring. Think about how Chapman and DeLapp quantified T’s progress using SUDS. There is another clue in the question that should prompt you to consider another useful area of the syllabus. The disorder being asked about is generalised anxiety disorder. What can you remember about the GAD-7? NOW TEST YOURSELF 6.45Outline one feature of systematic desensitisation as a treatment for fear-related disorders. [2] 6.46 Morag faints every time she sees blood. Explain how and why Morag might benefit from applied tension. [4] 6.47 Suggest one reason why researchers may be cautious about making generalisations from their findings. You should refer to one study of fear-related disorders in your answer. [2] 6.48 aPlan a study using self-reports to investigate the effectiveness of cognitivebehavioural therapy for people with generalised anxiety disorder. Your plan must include details about: – question format (open and closed questions) – scoring/interpretation. [10] b Describe one piece of psychological knowledge on which your plan is based. [4] 6.5 Obsessive-compulsive disorder 6.5.1 Diagnostic criteria (ICD-11) Symptoms of obsessive-compulsive disorder (OCD) include: » obsessions: repetitive, persistent thoughts and images that are unwanted and intrusive » compulsions: repetitive behaviours, such as tapping (physical) or sub-vocal counting (mental), often to neutralise obsessive thoughts. For a diagnosis, these obsessions and compulsions must take up at least an hour per day and symptoms must cause distress/dysfunction. Insight is variable, either poor–absent or fair–good. Relevant research: Rapoport (1989) Aim: to investigate OCD in a teenage patient, including efficacy of drug treatments. Methodology: » Case study of Charles (age 14), who was obsessed with stickiness; compulsive washing took many hours a day. » Researcher conducted an EEG. » He was prescribed clomipramine (a tricyclic antidepressant). Results: » Charles spent all night washing after the EEG due to the stickiness of the electrodes. » Four weeks after starting clomipramine, he poured/touched honey. » He relapsed within 12 months due to tolerance, but symptoms reduced. Conclusions: clomipramine is effective in the short term but maintenance doses are required to prevent relapse. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 125 125 14/08/23 7:19 PM SKILLS BUILDER Using research evidence, explain one way that obsessive-compulsive disorder could affect a person’s ability to function in everyday life. [2] By the end of this chapter, you will have learned about two children with OCD: Charles and Jason. Everyday functioning for children typically involves going to school, so you might want to explain how Charles’ time-consuming compulsions made this impossible. Try to avoid giving generic information that does not really answer the question. For example, daily medication helped Charles to function in everyday life but this knowledge doesn’t fit this specific question and would be unlikely to gain credit. ▼ Table 6.38 Evaluating Rapoport (1989) Strength Weakness Qualitative data – open question responses provided Generalisation – one 14-year-old boy may not be detailed insight into Charles’ beliefs, such as ‘What would representative of other age groups (children often count, happen if your washing routine was disrupted?’. check and repeat movements; adults tend to ruminate). SKILLS BUILDER Suggest one way a researcher could increase the reliability of data collected as part of a case study. [2] Reliability is an important concept and understanding ways to improve it will also help you in ‘Plan a study’ questions. Think about Rapoport’s observations of Charles pouring honey, for example. She could have filmed him and asked another person to watch and record Charles’ behaviour to test for inter-observer reliability. You could justify why your idea would increase the consistency of the data. Be careful not to deviate into a discussion of objectivity. Measures The Maudsley Obsessive-Compulsive Inventory » The Maudsley Obsessive-Compulsive Inventory (MOCI) includes 30 true and false statements developed through interviews with 30 people with OCD. » Sample item: ‘I avoid using public telephones because of possible contamination.’ » The MOCI categorises respondents into four types: cleaning, checking, slowness and doubting. The Yale-Brown Obsessive-Compulsive Scale » The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) uses a semi-structured interview schedule with ten items measuring symptom severity (mild to extreme) on a five-point scale (0–4). » An accompanying checklist can be used to diagnose OCD type. » Interview duration = 30 minutes. ▼ Table 6.39 Evaluating the diagnosis and measurement of OCD 126 Strengths Weaknesses MOCI Reliability – 50 students completed the MOCI twice one month apart; 89 per cent responses were the same. Validity – fixed-choice questions force people to make a decision and items are subjective. For example, ‘I use an average amount of soap’ (average for whom?). Y-BOCS Reliability – agreement was excellent when four interviewers assessed 40 people with OCD. Validity – difficult to report on symptoms in ‘the last week’ if symptoms were worse on some days than others. SKILLS BUILDER Zoubir is a trainee clinical psychologist. He is testing the validity of a new structured interview schedule to assess the severity of OCD symptoms. Plan a correlational study that will help Zoubir with this goal. [10] You will need to consider all the general features involved in planning a study. You will also need to focus on how Zoubir will measure two co-variables that can be plotted on a scatter graph in order to assess the validity of the interview schedule. Can you suggest a suitable directional hypothesis for Zoubir’s study? Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 126 14/08/23 7:19 PM 6 Clinical Psychology SKILLS BUILDER Evaluate measures of obsessive-compulsive disorder, including a discussion of quantitative and qualitative data. [10] Read through the information in this section about the Y-BOCS and the MOCI and create a Venn diagram to pick out similarities and differences. This should help you to begin evaluating these measures. One of the first things you will notice is that, while they are both self-reports, one is a questionnaire and the other is a semi-structured interview. Both result in quantitative data though.

NOW TEST YOURSELF 6.49 Explain one strength of quantitative data using the Y-BOCS as an example. [2] 6.50Romash has been having intimate thoughts about his neighbour Jessie. He feels ashamed and disgusted. Romash feels better if he vigorously scrubs his bathroom but he is now spending hours cleaning when he should be studying. Explain one or more reasons why Romash may fit the diagnostic criteria for OCD.

[2] 6.5.2 Explanations of obsessive-compulsive disorder Biological explanations Genetic OCD appears to be inherited: » 37 per cent of people with OCD have a parent with OCD (Lewis, 1936). » Concordance rates: MZ twins = 87 per cent; DZ twins = 47 per cent. OCD is polygenic and frequency of certain alleles is more/less common in people with OCD. For example: » Allele 2 of the DRD4 gene is less common in people with OCD. » Low activity allele of the COMT gene is more common in people with OCD. » Under-expression of the SLITRK5 gene is linked to OCD. SKILLS BUILDER Peggy is interviewing people with obsessive-compulsive disorder to investigate whether any of their relatives also have the same disorder and if so, whether they share similar symptoms. Peggy has asked you to help her to think about the interview format and sampling technique. Which format and technique would you choose? a State two reasons for your choice of interview format. [2] b Explain one reason for your choice of sampling technique. [2] The interview can have a structured, semi-structured or unstructured format. You will need at least two strengths and two weaknesses of each. This question requires you to use the strengths that you have learned as reasons why Peggy should use this format. You will need to think carefully about the topic of Peggy’s interviews and how the format of the interview could affect the validity and reliability of the data. Likewise, think about the most practical way to recruit a sample of people with OCD. You need to know how random, volunteer and opportunity sampling affect generalisability in order to decide upon the best technique. Sometimes the most scientific is not always the most practical.

This may be caused by abnormalities relating to: » presynaptic serotonin reuptake » postsynaptic receptors, such as D4 dopamine » enzymes such as MAO-A (see page 106). SKILLS BUILDER explanations assume OCD is inherited’, show that [6] you understand what inherited means. You could say something like: ‘First-degree relatives of people with You could discuss genetics and biochemicals here. OCD are more likely to also have the disorder than Show both knowledge and understanding in your more distant relatives as they share more DNA.’ response. For example, instead of saying ‘genetic Describe the biological explanation of obsessivecompulsive disorder. Psychological explanations Cognitive (thinking error) » People with OCD find it impossible to ignore passing thoughts. » They make a thinking error; all thoughts must be meaningful and significant. » The thoughts themselves are not problematic; the meaning attached to them causes distress (e.g. shame, disgust). » Thought-action/event fusion: people believe that imagining a certain action or event increases its probability. » Compulsions are seen as a way of neutralising obsessive/negative thoughts. » Personal responsibility for negative outcomes may be overestimated, leading to anxiety. SKILLS BUILDER Roxy and Dana are discussing the cognitive explanation of obsessive-compulsive disorder. Roxy thinks it is more of an individual explanation, whereas Dana thinks it could also be seen as a situational explanation. Explain whether you agree more with Roxy or with Dana. [2] There is no right or wrong answer, so long as you can justify your reason. Individual explanations suggest that OCD is caused by dispositional factors that differ between people, whereas situational explanations emphasise environmental cues which trigger OCD symptoms. You need to state whether you agree more with Roxy or Dana and give a reason. Then elaborate by stating why the information you have presented supports either an individual or a situational explanation. Behavioural (operant conditioning) » Compulsive behaviours develop as they help to reduce negative feelings. » Actions are repeated as they are negatively reinforced. Psychodynamic » OCD symptoms are a defence mechanism. They protect the person from becoming aware of unresolved conflicts from the unconscious mind. » The id’s desires may be expressed through obsessional thoughts. » Compulsive acts may result from excessive guilt generated by an overly dominant superego. » Unresolved conflicts stem from early childhood, specifically during the anal stage of psychosexual development (age 1–3): – Potty training that is too early or too harsh may result in fixation at this stage. Obsessive traits include orderliness and perfectionism. 128 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 128 14/08/23 7:19 PM 6 Clinical Psychology SKILLS BUILDER Compare the genetic explanation and the psychodynamic explanation of obsessive-compulsive disorder. [4] Anywhere that you see two or more explanations in the syllabus, be prepared for a compare question. You may present either two similarities, two differences or one of each. Comparison points usually include both explanations within the same point, using connectives such as ‘likewise’ (similarity) and/or ‘whereas’ (difference). You could compare the explanations with regards to issues and debates (e.g. ‘the genetic explanation is more reductionist because … whereas the psychodynamic approach is more holistic because … ‘) or applications to everyday life. ▼ Table 6.40 Evaluating explanations of OCD Biological Psychological Strengths Weaknesses Evidence – silencing the SLITRK5 gene caused compulsive grooming and hoarding behaviour in mice (Shmelkov et al., 2010). Validity – exercise caution when extrapolating data from mice to humans. Mice can only display compulsions; this does not explain the origin of obsessions. Applications – led to the development of drug treatments, such as clomipramine (see Rapoport, 1989, see page 125). Comparison – high concordance rates in family studies can also be explained by nurture (e.g. modelling). Evidence – people with ‘checking-type’ OCD reported decreased urges and distress when told that they were not responsible for negative outcomes (Lopatka and Rachman, 1995). Unscientific – psychodynamic concepts such as id and superego are unfalsifiable; there is no evidence that people with OCD are more likely to have experienced conflicts aged 1–3. Applications – therapies such as exposure and response prevention (ERP; see page 130) were developed as a result of psychological theories. Comparison – psychological explanations cannot explain genetic evidence, such as the low frequency of allele 2 of the DRD4 gene in people with OCD. Issues and debates Individual and situational explanations All the explanations give individual accounts of OCD, focusing on the person rather than the situation – for example, inherited genes make some people vulnerable. Research shows that symptom severity is affected by situational factors such as temperature (Brierley et al., 2021). Nature versus nurture OCD prevalence is universal, supporting nature, but there are cultural differences in how symptoms manifest, supporting nurture (Fontenelle et al., 2004). Psychological explanations cannot explain case studies such as Thobois et al. (2004), in which a blood clot on the caudate nucleus led to OCD symptoms. NOW TEST YOURSELF 6.53Using an example, describe one ‘thinking error’ in people with obsessive-compulsive disorder. [2] 6.54 Explain one similarity and one difference between biological and psychological explanations of obsessive-compulsive disorder. You must refer to reductionism versus holism in your answer. [4] 6.55 Explain one application to everyday life of the biochemical explanation of obsessive-compulsive disorder. [2] 6.56You are planning a naturalistic observation to investigate the behavioural explanation of obsessive-compulsive disorder.

Psychological therapies: exposure and response prevention » Environmental cues that trigger obsessions are identified and rated using SUDS (see page 124). Cues are arranged into a hierarchy. » Clients are exposed to the lowest rated cue until habituation (SUDS decreased to 50 per cent below baseline). » Therapists prevent compulsive acts. Clients must learn to reduce anxiety in other ways. » Homework includes graduated exposure tasks and recording change in SUDS. » Relaxation exercises and anti-anxiety drugs are banned. People must learn that anxiety goes up but also comes down on its own. Relevant research: Lehmkuhl et al. (2008) Aim: to investigate the efficacy of CBT for a child with Autism Spectrum Disorder (ASD) and OCD. Methodology: » Case study of 12-year-old Jason. » Obsession = contamination, compulsion = handwashing. » ASD symptoms = sensory issues, self-harm, limited and repetitive language and play, poor social relationships. CBT was adapted to his needs: » The therapist used phrases like ‘not letting OCD be the boss’. » Homework (e.g. touching elevator buttons) was reinforced using a reward chart. » Parents and teachers were involved. Results: » Y-BOCS score dropped from 18 to 3. » Three months later, Jason showed no signs of relapse. Conclusions: CBT can be personalised for children with additional needs. ▼ Table 6.41 Evaluating Lehmkuhl et al. (2008) 130 Strengths Weaknesses Validity – the study used method triangulation; primary data = observation, interview, psychometric tests (IQ test and Y-BOCS), secondary data = medical records. Case study – can only generalise with caution. Jason had average IQ and a lot of support at home/school. ERP may not work for all children with ASD. Replicable – an RCT with 46 adults with ASD supports the efficacy of ERP for this population (Russell et al., 2013). Application – ERP may only have been effective due to the skills of the specific therapist; other therapists may not form such effective therapeutic alliances.

[10] Now that you have almost reached the end of the clinical chapter, you should be quite familiar with ways of evaluating treatments. Start by discussing research evidence (e.g. Lehmkuhl et al., 2008; Lovell et al., 2006). Focus on how the findings demonstrate the efficacy of CBT and ERP. Compare the types of evidence they supply, such as the validity of Lovell et al. versus Lehmkuhl et al. You could also discuss how these therapies compare to the use of SSRIs. Most importantly, though, you need to address the named issue. Think about how the therapies can be adapted for children (e.g. Lehmkuhl et al.) and why psychological therapies might be preferred to drug treatments with child patients. Key study: Lovell et al. (2006) Context: » Weekly, in-person therapy is costly. Lengthy waiting lists can make it inaccessible. » New modes of delivery are being trialled, such as online/telephone. Aims and hypothesis: » Aim: to compare telephone versus face-to-face ERP treatment. » Hypothesis: telephone ERP is not less effective than face-to-face ERP. Research method(s) and design: » Method/design: randomised control trial, independent measures, random allocation, longitudinal. » Data collection technique: questionnaires (psychometric tests). Variables: » Independent variable: mode of ERP delivery – telephone versus face to face. » Dependent variable: compulsive behaviour checklist based on the Y-BOCS (see page 126), the BDI (see page 100) and a client satisfaction questionnaire. Sample: opportunity sample (n = 72) of 16–65-year-old outpatients with OCD from the UK (all scored 16+ on the Y-BOCS). Procedure: » Baseline symptoms were assessed by researchers twice, four weeks apart. The researchers were unaware of each participant’s mode of delivery (i.e. blind). » Symptoms were reassessed at one, three and six months after treatment. » ERP was delivered by experienced therapists. Controlled variables: » Therapy manuals were used to standardise treatment across different therapists/ clients. » Random allocation controlled participant variables. » The blinding procedure eliminated researcher bias. Ethics: protection from harm; ten people at increased risk of suicide were deselected. Results: » There was no significant difference in symptom severity between the telephone and face-to-face treatment groups before treatment or at any of the follow-up assessments. » Client satisfaction did not differ immediately after treatment. » Treatment was successful for 77 per cent of the telephone group and 67 per cent of the face-to-face group. Conclusions: telephone ERP for OCD is as effective as face-to-face therapy, despite 50 per cent less therapist contact time. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 131 131 14/08/23 7:19 PM SKILLS BUILDER a Plan a randomised control trial to test the effectiveness of SSRIs as a treatment for obsessive-compulsive disorder. Your plan must include details about controlled variables and a directional or non-directional hypothesis. [10] b For one piece of psychological knowledge on which your plan is based: [4] i Describe this psychological knowledge. ii Explain how you used two features of this psychological knowledge to plan your experiment. [4] Try to identify a study you have learned about with the same research method. This will provide you with ideas for your own study. Lovell et al. (2006) is an RCT comparing two modern versions of ERP. You can use some of the design features to help plan your study. For example, the researchers used an independent measures design with random allocation. You could randomly allocate your participants to either the SSRI group or a control group. You could use a study from another part of the chapter to help you if you wish. For example, Grant et al. (2008) compared opiate antagonists (for gambling disorder) with a placebo group. You could also use placebos in your study. For part b, think carefully whether you would rather write about Lovell et al. or Grant et al. Think about the similarities between their study and the one you are planning. You will need two identifiable features that inspired your planning – for example, double-blind design, use of a psychometric test (e.g. Y-BOCS). ▼ Table 6.42 Evaluating Lovell et al. (2006) Strengths Weaknesses Reliability – baseline measures were taken twice (test-retest). Validity – the blinding procedure broke down for 13 per cent of participants, reducing validity due to possible researcher bias. Validity – random allocation reduced the effect of participant variables, such as symptom severity, employment and marital status. Longitudinal design – 11 people dropped out. Attrition can lead to differences in key participant variables between the groups, reducing validity and generalisability. SKILLS BUILDER Explain why random allocation was used to assign participants to the two groups in the key study by Lovell et al. (2006) about telephone-administered cognitive-behavioural therapy. [2] If you are unsure about any of the methodological concepts mentioned, revisit them now (e.g. for random allocation, see page 59). Link your ideas to specific details from the study. Think about what was being measured (i.e. average Y-BOCS scores of people receiving telephone versus face-to-face ERP). Can you think of any individual differences that might have caused the average to be higher in one group than the other (besides the type of therapy)? Random allocation would mean that any difference in the Y-BOCS averages is more likely to be due to the type of therapy (the independent variable) than participant variables, such as comorbid disorders, age or gender. ▼ Table 6.43 Evaluating treatments for OCD Biological Psychological 132 Strengths Weaknesses Evidence – a meta-analysis of RCTs showed that 17 real drugs were superior to placebos. Individual differences – up to 60 per cent of people report no improvement. Comparison – low commitment and effort compared with psychological therapies, also cheaper and therefore more accessible. Applications – improvement can take 12 weeks; maintenance doses may be required to prevent relapse. Supporting evidence – see Lehmkuhl et al. (2008) and Lovell et al. (2006), both below. Applications – difficult to deliver for inexperienced therapists who sometimes fail to include relatives and friends, who reinforce OCD behaviours. Comparison – 86 per cent of ERP clients achieved a clinically relevant reduction in symptoms, compared with 48 per cent of people taking clomipramine. Applications – old compulsions may be replaced with new ones unless the therapist is able to reveal the core underlying fear.

(2006) only tested people in the UK, an individualist culture with a low power distance index (PDI). People from collective cultures and/or those with high PDI may respond less favourably. However, face-to-face ERP had long-term positive effects for men with OCD in Iran (Khodarahimi, 2009). Use of children in research Lehmkuhl et al. (2008) successfully adapted ERP for a child with additional needs. A strong rapport was developed with the family/teachers to develop a personalised plan and facilitate transfer of treatment outcomes to home/school environments. SKILLS BUILDER Floss is a cognitive-behavioural therapist. She is working with Manal, who has obsessive-compulsive disorder. Explain how cultural differences between Floss and Manal might influence the effectiveness of the treatment she provides. [2] Think about what you have learnt about the ways cultures differ from one another, such as individualism-collectivism and power distance index. You also need to think about key features of CBT (e.g. it is collaborative). If Manal is from a high PDI culture, he might see Floss as an authority figure and expect her to tell him how to recover. If Floss is from a low PDI culture, she might see Manal as an equal and expect him to participate in creating treatment goals. Once you have thought of some ideas, re-read the question. It is about effectiveness of treatment, so you need to think about whether these differences might make the treatment more or less effective and why.

Window displays trigger quick judgements about the store’s ability to meet consumers’ needs: » They are a cost-effective way to increase customer satisfaction and sales. » New products sell better when showcased with other accessories. Flowers/foliage and ornamental features (e.g. fountains) can: » improve mood/perceived quality of life » increase distances travelled/sales » enhance self-reported quality of the environment/products. Relevant research: Mower et al. (2012) Aim: to investigate the effect of window displays and landscaping on: » pleasure » arousal » liking of the external environment » purchase intentions. Methodology: participants read a description of a small boutique and completed an online questionnaire. Descriptions were identical, except the store had either: » plants outside or not » a mannequin in the window or not. Results: landscaping and window displays increased liking and purchase intentions but had no effect on mood.

Objective data – both Vrechopoulos et al. and Mower et al. use quantitative data (e.g. from rating scales) so no interpretation is necessary in the analysis. Questionnaires – in Vrechopoulos et al., participants may have assigned similar scores due to response set. In Mower et al., participants may have been more positive about purchase intentions due to demand characteristics. Issues and debates Cultural differences The same display might elicit different emotional responses based on shoppers’ cultural identity. Collectivists may prefer displays emphasising durability and function. Individualists may prefer displays that trigger emotional responses and enhance personal identity.

Aims and hypothesis: » Aim: to investigate the effect of classical versus pop music on diners’ spending. » Hypothesis: spending will be greater when listening to classical than pop music. Research method(s) and design: » Method: field experiment. » Design: independent measures. » Data collection technique: observation. Variables: » Independent variable: classical, pop or no music. » Dependent variable: average spend for each course, total bill and time in restaurant. Sample: opportunity sample of 393 male and female diners in an affluent UK town. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 137 137 14/08/23 7:19 PM Procedure: » A waitress recorded average spending in an expensive restaurant six nights a week for three weeks. » The restaurant played either classical, pop or no music. Controlled variables: volume, lighting, menu, temperature. Ethics: diners’ privacy was respected; lack of consent was justified. Results: average spending was greater for classical music compared with pop or no music for starters, coffees, total food bill and overall spend (see Figure 7.1). Conclusion: previous research is supported. Classical music may increase spending due to: » enhancement of other atmospherics » increased enjoyment/arousal » customers being ‘primed’ to spend more due to ‘upmarket’ image.

Reasons sound may affect taste perception » Noise is a stressor – sugar cravings increase due to the need for energy. » Research with rats found that sound activates 19 per cent of neurons in the olfactory tubercle. » Information from multiple senses combines when judging taste intensity. Taste is less intense when sound is louder. Noise distracts us from paying attention to taste. Greta is conducting an experiment on noise and taste perception. Participants rated the sweetness of a chocolate cake while listening to white noise or no noise. They wore blindfolds and headphones at all times. Explain why Greta asked the participants to wear headphones. [2] Avoid describing what headphones do (e.g. block noise in the testing room). Try to give reasons why these things were necessary. Focus on just one reason so you have time to elaborate. Relevant research: Woods et al. (2011) Aim: to investigate whether tastes are more intense in quiet versus noisy conditions; and whether background noise affects taste perception of hard versus soft foods. 138 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 138 14/08/23 7:19 PM 7 Consumer Psychology Methodology: participants rated sweetness, saltiness and liking for soft, hard, sweet and savoury foods while listening to loud, quiet or no white noise. Results: » Taste intensity was lower in the loud compared with the quiet condition. Sweet foods were affected more than salty foods. » Liking was highest in quietness and lowest in the noisy condition. » Hardness did not affect liking or intensity. Conclusions: sweetness and saltiness is negatively affected by noise, regardless of hardness/crunchiness. ▼ Table 7.5 Methodological issues Strengths Weaknesses Validity – confounding variables are controlled in both Generalisations – unrepresentative sample in North et studies. Woods et al. eliminate participant variables by using al. (wealthy, middle-class, United Kingdom). a repeated measures design; North et al. control situational variables such as decor and lighting. Replicability – in Woods et al., standardisation means the study can be replicated and tested for reliability (e.g. portion size of sample foods). In North et al, the music was at the same volume each night and the naming of artists/tracks means others could replicate the study. Validity – in Woods et al., participants wore blindfolds; in the real world, taste perception would also be affected by visual cues. Likewise in North et al., there was no control for musical preference, reducing validity. Issues and debates Individual and situational explanations Background music/noise is a situational factor that influences spending. Individual differences (e.g. musical preference, neurodiversity) may also affect spending and taste perception. Reductionism versus holism In North et al., a specific atmospheric (music) is isolated to determine its influence on spending, so the study is reductionist. Increased spending may be due to interactions between the music and other atmospherics. SKILLS BUILDER a Describe what psychologists have discovered about sound and consumer behaviour. [6] b Evaluate what psychologists have discovered about sound and consumer behaviour, including a discussion about individual and situational explanations. [10] You could include any of the studies from this section in your answer to either of these questions. The most obvious is North et al. as this is the key study. You could also include Woods et al., Zampini and Spence or Masuda et al. (2008). Very little information is provided about these last two studies but they can still be used to show breadth of knowledge. NOW TEST YOURSELF 7.5Outline what is meant by determinism, using an example from sound and consumer behaviour. [2] 7.6 Wolfgang and Antonio are eating popcorn at the cinema.

They influence feelings, decision-making and behaviour. All human emotional responses can be described in terms of three dimensions: » pleasure » arousal » dominance. ▼ Table 7.6 The effects of pleasure, arousal and dominance on consumer attitudes and behaviour Effect on consumer behaviour High Low Pleasure Approach behaviours (e.g. entering Avoidance behaviours are more stores, handling products) are likely when experiencing negative more likely when experiencing emotions. positive emotions. Arousal Alert consumers spend more due to Relaxed consumers spend less due higher product/staff engagement. to product/staff disengagement. Excess arousal decreases sales (overwhelming). Dominance Control/autonomy enhances positive emotions. The effects of dominance are unclear. STUDY TIP Try using scents to enhance your recall. Rosemary may enhance memory (Moss et al., 2003) because it contains a substance that inhibits the enzyme that breaks down acetylcholine (a neurotransmitter important for memory). Be careful – relaxing scents such as lavender may reduce anxiety but they can also impair working memory. Feeling restricted creates negative emotions/increased arousal. This may trigger avoidance. Odour and the PAD model » Olfactory nerves connect the brain’s memory and emotion centres. » Manipulating smells may alter emotions and trigger recall. » Scent marketing: signature scents can increase sales/brand loyalty: – Vanilla (warm scent) increased perceived crowding and spending on luxury/ premium items compared with eucalyptus (cold scent). – Scents may enhance product/environment perception and/or pleasure, arousal and dominance. Relevant research: Chebat and Michon (2003) Aim: to investigate whether scents change consumer behaviour by affecting emotions or cognition. Methodology: » Shoppers rated product quality, mall environment, pleasure and arousal while exposed to citrus scent or no scent. » Total spend on non-grocery items was recorded. Results: in the scent condition, mall environment and product quality were perceived as higher/better. This was not mediated by pleasure but arousal was higher. Conclusions: » Scents enhance perception of the environment and product quality. » Enhanced perception increases arousal and pleasure. » This supports cognitive over emotional factors. Crowding and the PAD model » Perceived crowding reduces pleasure/dominance and increases stress. » Increased arousal may increase spending; if arousal is already high, spending may decrease. 140 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 140 14/08/23 7:19 PM 7 Consumer Psychology ▼ Table 7.7 Types of crowding Type of crowding Description Effects Spatial crowding Poor layout negatively affects shopper movements Social crowding Discomfort when volume of shoppers exceeds need for personal space » Increased negative emotions/arousal » Decreased dominance » Differences in store, customer service, product perception and spending Relevant research: Machleit et al. (2000) Aim: to investigate relationships between expectation, perception and tolerance of crowding, and shoppers’ thoughts and feelings. Methodology: participants completed rating scales to measure perceived crowding, tolerance, expectations, emotions and satisfaction. ▼ Table 7.8 Example items from Machleit et al. (2000) Examples of measured variables Example items from questionnaire Perceived social crowding ‘The store seemed very crowded to me.’ Satisfaction ‘I was satisfied with my shopping experience.’ Emotions ‘I felt nervous.’ Crowding tolerance ‘I avoid crowded stores whenever possible.’ Results: » There was a negative correlation between crowding and pleasure/satisfaction. » Expected crowding eliminated the correlation between social crowding and satisfaction. Conclusions: the effects of spatial/social crowding are affected by situational factors, such as type of store, and individual differences, such as expectations/ tolerance. ▼ Table 7.9 Methodological issues Strengths Weaknesses Questionnaires – both studies used closed questions (e.g. rating scales). Statistics could be used to measure correlations (Machleit et al.) and difference between scent and non-scent conditions (Chebat and Michon). Quantitative data – in Chebat and Michon, shoppers rated products from ‘outdated’ to ‘up to date’, but they were unable to express opinions about these ratings. Replicability – Chebat and Michon used a standardised procedure (e.g. ten diffusers emitted scent every sixth minute), so it can be tested for reliability. Subjectivity – in Machleit et al., participants made comparisons between current and past shopping experiences. Ratings scales may be interpreted differently by participants in both studies. Issues and debates Individual and situational explanations Situational factors, such as ambient smell and spatial layout, affect pleasure, arousal and dominance (PAD). However, individual factors, such as cultural differences, past experiences, personality and mental health, can lead to varied responses to environmental features. Application to everyday life Scent marketing can be used to increase sales. Stores can be organised to limit negative effects of spatial and social crowding. SKILLS BUILDER Suggest two ways that research into the effects of crowding on shopper pleasurearousal-dominance could be applied in everyday life. [4] You could state one way relating to spatial crowding and one way relating to social crowding. For each application, you could say what should be done by whom and in what context. You could then follow up by explaining why such changes should be made and how they might affect shoppers’ pleasure, arousal and dominance. SKILLS BUILDER Brock is interested in cultural differences and how these affect consumers in crowded open-air markets. Plan an observational study to help Brock to investigate this. [10] Use features of Machleit et al. (2000), but take care – this study used questionnaires. Brock wants to carry out an observational study. How could he adapt this study? Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 141 141 14/08/23 7:19 PM Cultural differences Cultural differences determine the extent to which certain smells are perceived as pleasant/unpleasant. They also affect perceived crowding and whether this increases positive or negative emotions. SKILLS BUILDER a Describe Mehrabian and Russell’s pleasurearousal-dominance (PAD) model. [6] b Evaluate the effects of odour and/or crowding on shopper pleasure-arousal-dominance, including a discussion about cultural differences. [10] Part a requires a detailed description of the model. You could explain how high or low levels of PAD might affect a consumer and give examples. In part b, you could present evidence for and against the model, such as Machleit et al. (for) and Chebat and Michon (against). Think carefully – would the findings have differed if the study had been conducted in a different culture? NOW TEST YOURSELF 7.9Ravi plays exciting music from action movies in the car showroom where he works. His customers often comment on the scent of new leather in the air. Using the PAD model, suggest one or more reasons for Ravi’s choice of music and odour in the showroom. [2] 7.10 Explain one strength and one weakness of research on retail atmospherics. [4] 7.11 A consumer psychologist is investigating the effects of crowding on people at a food festival. He has decided to collect qualitative data. Explain one strength of the use of qualitative data in this study. [2] 7.12 Saffron works at a theatre. She is conducting a correlational study to investigate how crowding in the bar before a show is related to people’s evaluation of the show. Explain one way that Saffron can reduce subjectivity in her study. [4] 7.2 The psychological environment 7.2.1 Environmental influences on consumers Wayfinding in shopping malls Shopping mall designers should consider ways to: » increase legibility and spatial recall using landmarks (e.g. fountains/escalators), clear signage and maps » expose shoppers to new experiences/opportunities to increase enjoyment and spending. Relevant research: Dogu and Erkip (2000) Aim: to investigate how signage/maps affect wayfinding. Methodology: shoppers completed a questionnaire about the usefulness of ‘You Are Here’ maps and confidence in giving directions. Results: visit frequency and mall area browsed were positively correlated but unrelated to wayfinding. ▼ Table 7.10 Results from Dogu and Erkip (2000) Said signs were insufficient 60% Said ‘You Are Here’ (YAH) maps were insufficient 68% Claimed there were no YAH maps at the mall (there were in fact three) 47% Accuracy when asked to point in the direction of a randomly selected store 63% Conclusion: wayfinding and legibility are positively correlated. 142 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 142 14/08/23 7:19 PM 7 Consumer Psychology Relevant research: Gil et al. (2009) Aim: to investigate how spatial configuration and individual differences affect shoppers. Methodology: CCTV cameras tracked movements of 480 shoppers who were interviewed as they left a supermarket. Results: » Visit types included short, round, central and wave (Table 7.11). » Shopper types included: specialists, natives, tourists, explorers (typically lone females) and raiders (typically male) (Table 7.12). ▼ Table 7.11 Types of shopper visit Type of visit Shoppers’ movement Short trip A quick, in-and-out visit; few specific targets Round trip Up and along the main/furthest aisles with short episodes in the side aisles, mainly in the vegetable, fruit and bread sections Central trip Up the main aisle, then into the top aisles, back down the main aisle to the bottom side aisles and out Wave trip Up the main aisle, zigzagging left and right along the side aisles to the exit at the far end ▼ Table 7.12 The five types of shopper Type of shopper Description of shopper movements Aim of shopping trip The specialist A long time spent looking at a few items Top-up or non-food shop The native A long trip to specific aisles, likely to make purchase Main or top-up shop The tourist Fast movers staying mainly in the main aisles near the entrance, unlikely Food or non-food shop to purchase The explorer The longest trips, slowly doubling back down the aisles, buying a great deal Main shop The raider Fast-moving and decisive shoppers, clear preference for main aisles unless necessary to go further; highest number of male shoppers Top-up or for tonight Conclusions: shoppers with differing purposes exhibit different spatial/movement strategies. SKILLS BUILDER Consumer psychologists sometimes use CCTV to investigate spatial movement patterns, such as how shoppers move around a store. Explain two advantages of using CCTV in this way. You must refer to reliability in your answer. [4] Think about how and why psychologists use CCTV in this context. For example, CCTV footage can be video-recorded, meaning that two or more observers could watch the recording to check for inter-observer reliability. It is recommended to elaborate your points. ▼ Table 7.13 Methodological issues Strengths Weaknesses Ecological validity – everyday shopping trips were observed. Shoppers used their own money, unlike other studies. Validity – in Gil et al. (2009), shoppers knew their movements were being observed; behaviour may not be natural. Likewise, in Dogu and Erkip (2000), self-reports about wayfinding may have been affected by demand characteristics. Reliability – CCTV recordings meant inter-observer reliability could be established in Gil et al. Dogu and Erkip’s pointing task should achieve reliable results. Generalisations – in Gil et al., data was from one supermarket. Likewise, questionnaires in Dogu and Erkip were only completed at weekends at one very busy mall. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 143 143 14/08/23 7:19 PM Issues and debates Reductionism versus holism Both studies were holistic in their approach. Both collected qualitative and quantitative data, using a variety of methods. Idiographic versus nomothetic Both studies are nomothetic. Findings about legibility/wayfinding and shopper movement patterns are generalised to the wider population. SKILLS BUILDER Explain one strength of research into environmental influences on consumers from the holistic side of the debate. [2] Thinking about Dogu and Erkip (2000) and Gil et al. (2009), which one is more holistic? That is, which one considers complex interactions between factors and uses multiple research methods? Look back at the question – first, you could make a point about what it is that makes the study holistic. Next, you could say how this improves the findings/conclusions. STUDY TIP When answering ‘Plan a study’ questions like question 7.16 at the end of this section, link your plan to research evidence. Clues in the question can be used to select the best study (e.g. Dogu and Erkip). Use a familiar study to guide your decision-making. This will help with part b of the question, where you will need to summarise the study in about 100 words and focus on two specific features that inspired your plan. NOW TEST YOURSELF 7.13Outline the spatial movement patterns of ‘specialists’ and ‘raiders’. [2] 7.14 Helios is out shopping in a new town. He feels ill and needs to find somewhere to buy medicine. He decides to look for a ‘You Are Here’ map to find a pharmacy. Using research evidence, explain one reason why Helios may [4] find it difficult to find a pharmacy. 7.15Outline one ethical issue relating to the use of CCTV in research into spatial movement patterns of shoppers. [2] 7.16The owners of a new shopping mall want to investigate how easy shoppers find it to navigate the mall, and find the shops and facilities that they wish to visit. a Plan a study using a questionnaire to find out about wayfinding in shopping malls. Include details about question format and sampling technique. [10] b For one piece of psychological knowledge on which your plan is based: i Describe this psychological knowledge. [4] ii Explain how you used two features of this psychological knowledge to plan your study. [4] 7.2.2 Menu design psychology Relevant research: Pavesic (2005) Menus are valuable marketing tools that influence spending and loyalty. Evidence-based menu design is highly recommended. ▼ Table 7.14 Negative impact – common menu mistakes 144 Menu mistakes Explanation Poor design, including size Poor font size, layout, colour and size; items do not stand out; unattractive/forgettable; difficult to hold Over-emphasised prices Customers opt for cheaper rather than more expensive dishes Poor salesmanship Failure to showcase most profitable dishes Incongruent Incoherent branding; design does not match restaurant decor STUDY TIP For ‘relevant research’, try to oppose the points presented in the methodological issues tables. For example, if the table gives a strength relating to validity, try to create a validityrelated weakness. Systematically ‘arguing’ in both directions (for and against) will elevate your evaluation, possibly to the top band.

Reducing cognitive load » Diners spend 109 seconds viewing menus. » 60–70 per cent of customers choose the same 18–24 dishes. » Short, carefully organised menus are: – easier to process – more profitable. Eye-tracking Wearable eye-trackers collect data about visual attention. Data is presented using heat maps and gaze motion plots. Primacy and recency effects » First and last items are recalled better than middle items (Murdock, 1962). » Diners show edge bias with menu choices. Edge avoidance is also supported (Rubinstein et al., 1996). Relevant research: Dayan and Bar-Hillel (2011) Aim: to investigate whether menu position affects customer choices. Methodology: Study 1 – laboratory experiment: » Students chose an appetiser, entrée, drink and dessert. » Independent variable: position of menu item (see Table 7.16). » Dependent variable: how often each dish was selected. Study 2 – field experiment: » A 15-day study at a café in Tel Aviv, Israel. » Independent variable: position of menu item: – standard/control menu – experimental menu (items from top and bottom of the list were moved to the middle and vice versa). » Dependent variable: how often target items were purchased. ▼ Table 7.16 Sequencing of menu items Condition List order Example Baseline 1, 2, 3, 4 juice, Sprite, cola, Fanta Mirror 4, 3, 2, 1 Fanta, cola, Sprite, juice Inside-out base 2, 1, 4, 3 Sprite, juice, Fanta, cola Inside-out mirror 3, 4, 1, 2 cola, Fanta, juice, Sprite Results: » The majority of choices were from the first or last two dishes. » Croissant was chosen twice as often when it was first on a ten-item menu compared with fifth (18:9). Conclusions: dish popularity can be increased by moving dishes from middle to first or last position due to edge bias. SKILLS BUILDER Zeph runs a fish restaurant. He has a lot of expensive salmon that needs to be used up. Suggest one change Zeph could make to the menu to encourage diners to choose the salmon. [2] Think about how Zeph could encourage diners to choose the salmon using eye magnets or primacy/ recency effects. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 145 145 14/08/23 7:19 PM The effect of food name on menu item choice Descriptive wording on menus: » elicits positive emotions/anticipation » helps diners to make informed choices » reinforces branding. Relevant research: Lockyer (2006) Aim: to investigate effects of wording on menu choices. Methodology: » Participants rated the appeal of five versions of the same menu and discussed their reasoning in focus groups. » Questionnaires were developed based on the findings and randomly distributed. Results: » The seasonal menu was rated as ‘most appealing’ by 42 per cent of participants; 2 per cent rated the French menu as ‘most appealing’. » Simple, precise, appealing descriptions that increased perception of dishes as mouth-watering, fresh and natural were preferred. Conclusion: clear and precise descriptions are favoured and are most likely to affect menu choices. SKILLS BUILDER Lila works in a pizza restaurant that also serves cocktails and many flavours of gelato (ice cream). Plan a field experiment to help Lila to investigate how simple changes to the descriptions of each dish/drink influence sales. [10] Use features of Lockyer (2006) to guide you, but take care. This study involved a focus group. Lila wants to carry out a field experiment. ▼ Table 7.17 Methodological issues Strengths Weaknesses Generalisations – Lockyer (2006) sampled random households so data should be representative of the geographical region. Generalisations – opportunity sampling in Dayan and Bar-Hillel (2011) is unrepresentative (small coffee shop in a capital city). Validity – in Dayan and Bar-Hillel (study 1), confounding variables were controlled (e.g. dish price). Study 2 was a field experiment so ecological validity was increased as customers did not know they were being observed. Validity – in Lockyer, people in focus groups may have conformed with dominant views; social desirability bias may decrease honesty. Objectivity/subjectivity – in Dayan and Bar-Hillel, dish selection is an objective way of measuring customer preferences and the effect of edge bias. Objectivity/subjectivity – in Lockyer, analysis of qualitative focus group data required interpretation; conclusions may be affected by researcher bias. Issues and debates Application to everyday life Profits can be cheaply and quickly increased by adapting menus. Diners can also be directed to healthier, more nutritious options. SKILLS BUILDER a Describe what psychologists have discovered about menu design psychology. [6] b Evaluate what psychologists have discovered about menu design psychology, including a discussion about objective and subjective data. [10] Always look at part b before you start writing. As part b refers to objective and subjective data, you may want to include at least one piece of research in part a that can be evaluated in this respect. The study does not need to have collected both types of data – you could discuss how the usefulness of the findings would differ if another type of data had been collected. 146 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 146 14/08/23 7:19 PM 7 Consumer Psychology NOW TEST YOURSELF 7.17Nguyen is surprised when he discovers that he and six friends have all chosen the same dish at their local noodle bar. Using your knowledge of menu design psychology, outline one reason why Nguyen and his friends may all have chosen the same dish. [2] 7.18Outline one or more reasons why psychologists should be cautious when making generalisations from findings about primacy and recency effects and menu item choice. [4] 7.19 Klara is rewriting the menu for the school dining hall where she works. She wants to encourage the children to choose healthier options. Using your knowledge of research into food names and menu item choice, suggest one way that Klara could encourage children to choose more [2] fruit and vegetables. 7.20 Explain two strengths of eye-tracking as a way of researching the effects of menu design on consumer attitudes and behaviour. [4] 7.2.3 Consumer behaviour and personal space Key study: Robson et al. (2011) Context: banquette seating allows for six additional diners, increasing revenue by 37.5 per cent. However, this may: » increase customer discomfort through reduced privacy » reduce revenue in non-contact cultures. Aim: to explore perceived adequate distance between tables and how this is influenced by social context/familiarity and culture. Research method(s) and design: » Method: experiment. » Design: independent measure with random allocation. » Data collection technique: web-based questionnaire with images of restaurant tables. Variables: » Independent variables: table spacing – 6, 12 or 24 inches apart; dining partner – a business colleague, friend or romantic partner. » Dependent variables: seven-point Likert scales (1 = strongly disagree to 7 = strongly agree), measuring beliefs, emotional responses and behavioural intentions. Sample: » Size: 1,013. » Demographics: American, majority white (80 per cent), 53 per cent female; 6.1 per cent under 21 years old, 39 per cent over 50. » Sampling technique: survey link shared by a sampling company. Procedure: participants were told to answer questionnaires as though they were dining with one of three different types of dining partner (see above). Controlled variables: random allocation controlled for participant variables. Ethics: » Confidentiality was maintained – personal data was recorded, such as gender, but there was no identifying information. » Privacy was not invaded, as might be the case if observed in a restaurant. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 147 147 14/08/23 7:19 PM Results: the less distance between the tables, the more uncomfortable and dissatisfied the customers felt and the less privacy they felt they had (see Tables 7.18 and 7.19). ▼ Table 7.18 Participants’ reactions to different table spacings Table spacing Participants’ reactions 6 inches Participants worried about being overheard, disrupting others; 70 per cent said they would ask to be reseated; particularly stressful in the romance scenario. 12 inches There were negative feelings but respondents felt more in control than those in the 6 and 24 inch groups. 24 inches This was the condition with least negativity, yet 35 per cent said they would feel uncomfortable. ▼ Table 7.19 Effect of individual differences on attitudes and preferences Individual differences Effect on attitudes/preferences Age Younger participants were more positive than older participants at 6 inches and more stressed at 24 inches. Gender Women felt more stress, less control and greater discomfort than men, who felt more arousal at each distance. Ethnicity Asian participants were more comfortable and in control at both 6 and 24 inches than other groups. Frequency of restaurant visits Frequent restaurant diners were more comfortable at all distances than non-frequent diners. Residence People from densely populated areas were more aroused by close proximity than those from less densely populated areas. Conclusions: » Consumers, especially women, dislike closely spaced tables, especially for romantic dates. Personal space and Hall’s four zones Hall (1966) pioneered the study of proxemics, including: » the four interpersonal distance zones (see Table 7.20) » how individual and situational factors affect interpersonal distance. ▼ Table 7.20 The four zones of personal space (Hall, 1966) Zone Who can enter? Size of zone Intimate Romantic partner, children and other close family and friends <46 cm Personal Friends, family, colleagues 46–122 cm Social Acquaintances, strangers 122–210 cm Public The wider, more impersonal space, reserved for public lectures/speeches, etc., more anonymous >210 cm ▼ Table 7.21 Factors affecting personal space 148 Factor Effect on size/shape of personal space ‘bubble’ Position of other person/ intruder ‘Bubbles’ may not be circular; people are more comfortable with others standing/sitting to the side rather than in front/behind. Individual differences Gender, age, culture, autism and traumatic brain injury (TBI) also affect the size/shape of the ‘bubble’. Social context/situation Crowding; intimacy of the relationship and familiarity with others typically reduce the need for personal space. SKILLS BUILDER Explain one function of personal space. Refer to the key study by Robson et al. (2011) in your answer. [2] This question requires a good working knowledge of the syllabus, which refers to three functions: overload, arousal and behaviour constraint. Try explaining how and why diners feel uncomfortable at 6 inches apart using all three and decide which is the easiest to explain within the time limit.

Relevant research: Milgram et al. (1986) Aim: to investigate factors affecting reactions to queue jumpers, including reactions of other queue members. Methodology: » Confederates tried to queue jump 129 times in various locations in New York. » The independent variable was whether the people positioned before and after the queue jumper were also confederates or not and how many people attempted to queue jump – one or two. Confederate queue members (buffers) did not react to the intruder(s) and faced forward. » Responses were noted by a non-participant covert observer. Results: ▼ Table 7.22 Type and frequency of objections Type of objection Examples Frequency Physical Touching, sleeve tugging, shoulder tapping, pushing 10% Verbal ‘Excuse me, you have to go to the back of the line’ 22% Non-verbal Hostile stares and gestures 15% ▼ Table 7.23 Frequency of objections under the different conditions Number of intruders Number of buffers Frequency of objections 1 0 54% 1 25% 2 5% 0 91% 1 25% 2 30% 2 Conclusions: objections to queue jumpers are more common with two intruders and no buffers. SKILLS BUILDER Gary and Greg love watching football but hate queuing for hotdogs at half time. They often try to ‘ jump’ the queue. Using your knowledge of consumer psychology, explain how other people in the queue are likely to respond to Gary and Greg’s behaviour. [4] This question includes the words ‘jump’ and ‘queue’, which should cue you to think about Milgram et al. (1986). You could focus on the findings and relate them to Gary, Greg and the other people at the football match. For example, Milgram et al. found that people responded with verbal disapproval 22 per cent of the time and physical acts 10 per cent of the time. This means Gary and Greg are more likely to be shouted at than punched. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 149 149 14/08/23 7:19 PM ▼ Table 7.24 Methodological issues Strengths Weaknesses Quantitative and qualitative data – Milgram et al. (1986) tallied objection types (quantitative) but also gathered field notes to provide contextual information (qualitative). Robson et al. provided tables and graphs so findings can be quickly understood and used by restaurant managers. Observation – in Milgram et al., naturalistic settings (ticket counter, betting shop) may make it difficult to remain covert and lack of control over confounding variables could decrease validity. Ethics – in Robson et al. (2011), the use of questionnaires Ethics – Milgram used deception (confederates, covert meant participants were not made to feel actual observation). No consent or right to withdraw was given. discomfort through invasion of their personal space. Public places were used but harm was still possible. Issues and debates Individual and situational explanations Situational factors such as the social context determine how we feel about the proximity of other diners (e.g. who we are dining with) and reactions to behaviours such as queue jumping are affected by proximity and buffers. Individual factors such as culture, gender, age and neurodiversity influence personal space and how people respond to violations of social norms, such as queue jumping. Cultural differences Mean annual temperature and preferred interpersonal distance are negatively correlated, so the hotter the country, the less need for personal space. People in short-term orientation cultures (e.g. the US) might be more likely to object to queue jumpers than people in long-term orientation cultures. SKILLS BUILDER a Describe what psychologists have discovered about consumer behaviour and personal space. [6] b Evaluate what psychologists have discovered about consumer behaviour and personal space, including a discussion about observations. [10] Essays may be phrased at the subtopic level (e.g. ‘Consumer behaviour and personal space’). Remember which research is identified in each subtopic (e.g. Robson et al., 2011). Milgram et al. (1986) would be a good choice for these questions as they used covert observation so you could evaluate their research in part b. Remember, part a should focus on the findings of research (the discoveries) and part b should focus on the strengths and weaknesses of the methodologies of the studies that led to these discoveries; weaknesses of the studies mean that the discoveries are also questionable. NOW TEST YOURSELF 7.21Outline what is meant by the nomothetic approach, using an example from consumer behaviour and personal space. [2] 7.22 People often try to jump the queue at airports. Sometimes people ignore the queue jumper; other times they confront them, verbally or even physically. Outline one individual factor and one situational factor that influence how people respond to queue jumpers at airports. [4] 7.23 Suggest one way in which personal space at restaurant tables could be studied, other than using a questionnaire.

Buying a chocolate bar: utilitarian value is decided based on hunger and liking. For: requires time and effort; leads to optimal purchases (high utilitarian value). Satisficing theory (Simon, 1956) Rational choices are impossible due to missing information and limited processing capacity; bounded rationality allows for ‘good enough’ choices based on what will satisfy us and will suffice (Simon, 1991). Buying a car: the car we buy will ‘suffice’; it has the majority of our ‘must have’ features but may not meet all of our original criteria. Despite this, we will be satisfied with our purchase. For: less time and effort than utilitarian decision-making; explains individual differences – aspiration level varies based on personality and experience. Against: aspiration level = subjective concept; ‘He bought that because of his aspiration level; his aspiration level must be this because he bought that’ – this is circular reasoning. Prospect theory (Kahneman and Tversky, 1979; Tversky and Kahneman, 1981, 1992) Humans have a tendency towards loss aversion. Loss is feared more than gain is valued, leading to risky, seemingly irrational decision-making. Investing in combating rare, potentially fatal disease: if information was phrased in terms of: » lives saved: people preferred a smaller certain outcome over a larger possible outcome » lives lost: people avoided smaller certain losses, favouring risky options, possibly leading to a larger number of possible losses. For: can be used to inform advertising campaigns – for example, focusing on losses avoided if consumers purchase certain products or shop at certain places. Against: supporting evidence is eurocentric; people in collectivist cultures are less loss averse than those in individualist cultures (Wang et al., 2016). Against: regrets more likely due to not finding the ‘perfect’ purchase. ▼ Table 7.26 Strategies of consumer decision-making Strategy Explanations Example Evaluation Compensatory Pros and cons of limited options are weighed; positive attributes compensate for negatives; value is based on personal evaluations. Buying a plane ticket: more expensive, but direct route is chosen over cheaper, indirect ferry ticket. For: appeal of comparison websites is explained (Todd and Benbasat, 2000). Against: ignores emotion in decision-making; reductionist. Non-compensatory Used when deciding between many options and time and information are limited. Negatives not compensated for by positives – products are simply rejected. Buying a new smartphone: you want an 8-megapixel camera; all phones without this feature are rejected. For: quicker and easier than compensatory; explains individual differences – different people value different attributes. Against: suitable products may be excluded early on; may not make optimal choices. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 151 151 14/08/23 7:19 PM Strategy Explanations Example Evaluation Partially compensatory Attributes of two competing products are evaluated; the best is retained and compared with the next until the product with the most positive features remains. Choosing wedding venue: two venues with desirable attributes are compared (e.g. seats 150 guests, attractive gardens); one venue eliminated and the winner is compared with the next listed venue. For: rational and holistic strategy that allows for individual differences/personal preferences. Against: time-consuming to make a decision. Relevant research: Jedetski et al. (2002) Aim: to investigate factors affecting consumer decision-making, including: » possibility of comparing products or not » number of products (e.g. >100 versus <30). Methodology: » Twenty-four participants purchase items (e.g. baby monitors, golf clubs) from a website where products can be compared (CompareNet) or not (Jango). » Dependent variable: decision-making strategies. » Participants completed seven-point Likert scales, such as ‘I am confident that I made a good decision.’ Results: » Non-compensatory strategy was used more on Jango than CompareNet; and when there were more than 100 different products to consider. » Satisfaction was greater with CompareNet than Jango. Conclusions: compensatory strategy is more common when product comparison is possible; non-compensatory is more common with many possible alternatives. SKILLS BUILDER Compensatory strategies have been researched using rating scales to measure consumer attitudes. Give one difference between rating scales and forced/fixedchoice questions as a way of investigating consumer decision-making. [4] This question tests your knowledge of the additional research methods required for A Level compared with AS Level. Refresh your knowledge of forced/ fixed-choice questions on page 62. The command term is ‘give’, which means you do not have to describe why rating scales are better or worse than forced/fixed-choice questions, just describe how they differ. You could give an example of a rating scale from Jedetski et al. (2002) and show how the question would have changed if forced/fixed-choice. ▼ Table 7.27 Methodological issues Strengths Weaknesses Internal validity – it was an independent measures design; participants bought items on only one website, so there were no order effects. Ecological validity – this was low as participants were asked to purchase products they didn’t want/need. Questionnaires – Seven-point Likert scales meant participants were not forced to agree or disagree. Generalisations – Sample size was very small. There were only 22 in each group and only two websites were sampled. Issues and debates Determinism versus free will Jedetski et al. (2002) showed online decision-making is determined by available comparison tools and number of options. Free will may play a smaller role than we think. 152 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 152 14/08/23 7:19 PM 7 Consumer Psychology Reductionism versus holism Utility theory and compensatory strategy assume we are rational and that we reduce consumer decision-making to a mathematical weighing up of pros and cons. However, decisions may be automatic, impulsive and emotional. A holistic approach to understanding these processes may result in models with better predictive power. SKILLS BUILDER a Describe what psychologists have discovered about consumer decisionmaking. b Evaluate what psychologists have discovered about consumer decisionmaking, including a discussion about determinism versus free will. [6] [10] These may seem like difficult questions as you only have one study in this subtopic, on internet shopping and website design. However, you could include anything from the sections on choice heuristics (see page 153) and mistakes in decision-making (see page 156). Think about the implications of believing that our behaviour is determined by internal/external forces (e.g. people cannot be held accountable for overspending on impulse purchases). STUDY TIP Try writing an alternative and null hypothesis for Jedetski et al. (2002). Remember, hypotheses can be directional or nondirectional, correlational or experimental, null or alternative. Refresh your memory of these terms on page 72, if you need to. Writing hypotheses for each study is a good way of processing the information at a deeper level, making future recall more likely. But remember – a good hypothesis will always mention both variables, fully operationalised. If you do not know what this means, check page 72.

Using satisficing theory, explain one reason Paulo may settle for a bike without all of these features. [2] 7.28 Explain two limitations of utility theory relating to consumer decision-making in [4] everyday life. 7.3.2 Choice heuristics ▼ Table 7.28 Choice heuristics Explanations Example: buying shampoo Availability Decisions are determined by products that come readily to mind. Less easily remembered brands are ignored. You choose a brand you have just seen advertised. Representativeness Choosing products based on an image we have of ourselves or how we believe we will benefit by using them. You choose a brand with similar packaging to a luxury brand, particularly if advertising features an aspirational image. Recognition Unfamiliar brands/products are chosen based on recognition of similarities with familiar products, as long as there are no negative connotations. When abroad, you choose an unfamiliar local brand because the packaging is the same colour as your regular brand. Take-the-best A single attribute is prioritised; all others are ignored. ‘This shampoo is for blonde hair. I have blonde hair and so I will buy it.’ Anchoring A product’s perceived value is relative to a previous product, which acts as an anchor/ baseline. A shampoo displayed next to a more expensive product is more likely to be purchased than one next to a cheaper product.

She arranges hampers of various sizes/prices side by side and showcases her pricier items in her window display. Explain how one or more choice heuristics may affect consumer decision-making in Shelley’s shop. [4] Identify key words in the question and read the extract again with these words in mind. This should help you to identify helpful parts of the extract for answering the question. Here, the key term is ‘choice heuristics’. Think of a way to help you remember them all – for example, 2A, 2R, 1T (availability, anchoring, representativeness, recognitions and take-the-best). Which heuristic best matches the extract? Be careful – the question is not just about heuristics, it is about their effect on decision-making. Make links to Shelley’s customers and what they might purchase and why. Point of purchase decisions Strategic advertising/promotions are used to encourage unplanned ‘impulse’ purchases. ▼ Table 7.29 Strategic advertising/promotions Strategy Explanation Example Multiple unit pricing (MUP) Offering a reduced price for purchasing multiple units can lead to unplanned purchases; customers believe they are making long-term savings. ‘8 for $8’ generates higher sales than single item pricing (SUP), such as $1. However, ‘2 for $2’ or ‘4 for $4’ was no more effective than single item pricing. Suggestive selling, also Salespeople sometimes offer additional low-priced A salesperson offers shoe polish known as upselling products at the point of purchase, such as a or insoles at the counter when the product that complements products already chosen. consumer pays for new shoes. Relevant research: Wansink et al. (1998) Aim: to test the anchoring and adjustment model at the point of purchase. ▼ Table 7.30 Methodology and results from Wansink et al. (1998) 154 Study Methodology Results Field experiment 1 86 shops were randomly allocated to SUP or MUP of toilet rolls, sweets and soft drinks. Weekly sales were compared with the six-month average. MUP increased sales by 32 per cent compared with SUP promotions. Field experiment 2 Cans of soup were advertised in three supermarkets at 79 cents, Sales increased as the limit with a limit of either four or twelve cans per person, or no limit. increased. Laboratory experiment 1 Six products were offered at 20 or 40 per cent off or at normal price. Advertising either did or did not include a high anchor – for example, ‘Buy them for your freezer’ versus ‘Buy 18 for your freezer’. High anchors increased purchase quantity intentions, even without a discount. Laboratory experiment 2 Students were shown scenarios involving 25–30 per cent discounts on single units of snacks. External anchors were purchase limits of 14, 28 or 56 units. Participants were asked, ‘How many of this product do you usually buy at a time?’ (default internal anchor) or to imagine situations in which they might consume the product. They were then asked, ‘How many of this product do you think you might use in the next month?’ (expansion internal anchor). Purchase intentions: » no internal anchor = 7.1 (increased with external anchors) » default internal anchor = 5.2 (regardless of external anchors) » expansion internal anchor = 10.3 (regardless of external anchors). Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 154 14/08/23 7:19 PM 7 Consumer Psychology Conclusions: point of purchase decisions are affected by situational factors (e.g. external anchors presented through MUP and purchase quantity limits) and by individual factors (e.g. internal anchors). Relevant research: del Campo et al. (2016) Aim: to investigate whether choice of heuristic (recognition versus take-the-best) depends on individual decision-making style. Methodology: » Participants in Austria and Spain chose a box of eggs from five sample products. They were randomly allocated to one of two groups: 40 seconds to choose or no time pressure. » They had to explain their choice and complete a questionnaire to measure decision-making style (rational, intuitive, dependent, avoiding or spontaneous). Results: » In the time pressure condition, take-the-best was used in Austria, but not in Spain. » Dependent and avoiding styles were expected to favour recognition, but this was not supported. » In Austria, but not in Spain, recognition was favoured by those with a spontaneous decision-making style. Conclusions: » Distribution of decision-making styles is similar across cultures, but there are cross-cultural differences. » The choice of heuristic is determined by decision-making style. ▼ Table 7.31 Methodological issues Strengths Weaknesses Experiments – in Wansink et al. (1998), field and laboratory experiments mean findings have high ecological and internal validity. In del Campo et al., control over labelling of egg cartons (e.g. price, country of origin) increases internal validity. Subjectivity – both studies measured purchase intentions; these are subjective opinions so may be more unreliable than measuring actual purchases (more objective). Quantitative – in del Campo et al. (2016), the strength of relationships between decision-making styles, time pressure and choice heuristics could be calculated. Likewise, in Wansink et al., counting soup cans purchased means data is objective and increases reliability. Quantitative – as all data is quantitative in Wansink et al., reasons for purchases and purchase intentions is unclear. In del Campo et al., decision-making style was measured using psychometric tests; no contextual information was supplied. Issues and debates Application to everyday life Store keepers and website owners can increase profits by employing evidence-based strategies such as MUP, consumer purchase limits and upselling. Individual and situational explanations Del Campo et al. (2016) demonstrated that choice of heuristic depends on situational factors (e.g. time pressure), but also individual differences (e.g. personal decisionmaking style). Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 155 155 14/08/23 7:19 PM STUDY TIP SKILLS BUILDER [2] Using an example, describe what is meant by ‘multiple unit pricing’.

She decides to investigate this in her local garden centre. a Plan a field experiment to help Gita investigate the influence of decision-making style on heuristics. Your plan must include details about controls/standardisation and choice of experimental design. [10] b For one piece of psychological knowledge on which your plan is based: i Describe this psychological knowledge. [4] ii Explain how you used two features of this psychological knowledge to plan your study. [4] ‘Plan a study’ questions, such as question 7.32 below, tend to focus on specific research methods (e.g. field experiments). The general and required features that you need to include are outlined on page 52–53 of the Cambridge International Psychology A Level syllabus. One general feature is ethics, so in question 7.32 think carefully about the considerations Gita should make. Also, as it is a field experiment, location is a critical required feature. The question tells you the location is a garden centre but to show you are thinking clearly and making the study replicable, you should give more information about exactly where in the garden centre the study would take place (e.g. in the furniture or tools section). 7.3.3 Mistakes in decision-making Thinking fast and thinking slow » In his popular book in Thinking, Fast and Slow, Kahneman (2011) explains why people are not always logical and why decisions are sometimes unpredictable. » He outlines two types of thinking: System 1 (fast) and System 2 (slow). ▼ Table 7.32 System 1 and System 2 types of thinking System Description When it is used Examples System 1 Fast, intuitive, automatic, unconscious and effortless; ‘best guess’ Automatic, especially when time-pressured and overloaded with information Non-compensatory strategy (page 151); heuristics (page 153); external anchors (page 154); buying stocks when prices are rising and selling when they are falling (Shleifer, 2012) System 2 Slow, deliberate, uses all available information; logical, conscious, rational, controlled, effortful, statistical May override System 1 leading us to question our first choice/answer; time may be spent ‘fact checking’ our first response Utility theory (page 151); compensatory strategy (page 151); internal anchors (Wansink et al., 1998, see page 154); buying stocks when they are falling and selling when they are rising (Shleifer, 2012) Interaction between System 1 and 2: » System 2 sometimes uses information initially processed by System 1. » System 1 uses years of stored knowledge processed by System 2, to make fast, but expert decisions (e.g. experienced chess players). 156 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 156 14/08/23 7:19 PM 7 Consumer Psychology Shleifer (2012) discusses how, when using the representativeness heuristic (System 1 thinking), we: » ignore available evidence and rely on stored knowledge » over-emphasise the relevance of past trends/experience. More System 2 thinking could help overcome dysfunctional consumer behaviours. SKILLS BUILDER Bamba is shopping for a gift for his mother, while talking on the phone to his brother, Osei. He grabs a discounted jewellery set without thinking much about it. Osei compares prices of perfume online before deciding which is the best value but also something that their mother will really like. Explain System 1 and 2 thinking using Bamba and Osei as examples. [2] You need to avoid giving too much description of each type of thinking, otherwise you may not get time to refer effectively to Bamba and Osei. Try writing one sentence where you use at least three adjectives to describe the type of thinking and identify which brother is using this thinking style and why. Then do the same for the other thinking style. Aim for no more than 40–50 words. Key study: Hall et al. (2010) Context: » Many people cannot remember choices they have only just made – for example, which of two faces they said they found most attractive. » The study investigates choice blindness using smell/taste as opposed to visual stimuli (faces). » It was conducted in a naturalistic setting (supermarket) rather than a laboratory. Aim and hypotheses: » Aim: to investigate the effect of similarity, liking and incentives on choice blindness in a naturalistic setting. » Hypotheses: choice blindness will be less common when shoppers: – sample teas/jams with dissimilar tastes/smells – have a preference for one product over another – are offered a free sample of their preferred option. Research method(s) and design: » Method: field experiment. » Design: independent measures. » Data collection technique: structured interview. Variables: Independent variables: » whether participants were: – told they would receive a free gift or not – presented with teas/jams that were similar versus dissimilar » whether the experimenter secretly switched the products over or not. Dependent variables: » whether participants expressed a concern or not » if so, whether the concern was: – concurrent (expressed immediately) – retrospective (at the study’s end) – sensory change detection: different smell/taste detected second time round. Sample: » Size: 180 » Demographics: 66 per cent female; aged 16–80 (mean: 40). » Sampling technique: opportunity sampling; asked while at a supermarket in Sweden to take part in a quality control test. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 157 157 14/08/23 7:19 PM Procedure: » Shoppers tasted two jams and smelt two teas. » Preferences were measured on a ten-point scale. » Next, shoppers were asked to taste/smell their preferred product again. In reality, they were offered their least liked product using a ‘magic’ jar with two compartments; it contained both types of jam/tea without the participant realising. » Finally, they were asked about: the reasons for their preference; how difficult it was to discriminate between the two products on a ten-point scale; and how confident they were that they were offered the correct product. » Each participant tried two jams and two teas in a counterbalanced order; the jar was flipped when sampling either the teas or the jams. Controlled variables: neutral ambient odour; noise and density of shoppers (moderate); the ‘magic’ jar was flipped in exactly the same way each time; whether participants sampled jam or tea first was counterbalanced. Ethics: » Deception was involved, so there was no informed consent. » Approval was gained from the Regional Swedish Ethics Board, Lund. » Safeguards included debriefing, including right to withdraw or provide written consent, and confidentiality. Results: » Most participants (68 per cent) were choice blind (no concerns expressed): – Detection rates were higher with dissimilar pairings than similar pairings. – Switch detection (e.g. not choice blind) was more common when one of the products was disliked. » Unexpected outcome: in the tea condition, detection of the switch was less common (i.e. choice blindness) in the free gift group (20 per cent versus 46 per cent). Conclusion: choice blindness: » occurs in real-world settings involving smell and taste as well as vision » is not affected by consequences of decisions or difficulty differentiating between similar products. Relevant research: Burke and Srull (1988) Aim: to investigate the retroactive and proactive effects of competitive advertising. Methodology: » Students were shown 12 text-only magazine advertisements. They were asked to rate either: – the likelihood of buying each product – their interest in each product. » Two minutes later, they recalled the three products either shown earlier (retroactive effects) or later (proactive effects) in the 12 advert series. » The researchers also varied whether the 12 adverts showed: – varied brands and types of product – varied brands/same products – same products/same brand, varied models. Results: » Twice as much information was recalled when items were rated for purchase intention versus interest (review activity). » The best recall was for varied as opposed to same product/brand. » The worst recall was for early as opposed to late in the series (retroactive interference); effect was not moderated by review activity. Conclusions: » Retroactive interference affects recall of advertisements but this is improved by thinking about purchase intentions. » Proactive interference reduces recall. 158 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 158 14/08/23 7:19 PM 7 Consumer Psychology ▼ Table 7.33 Methodological issues Strengths Weaknesses Experiment – control of confounding variables means cause and effect can be established in both Hall et al. (2010) and Burke and Srull (1988). Researcher bias was controlled in Burke and Srull through use of a double-blind design; randomisation controlled order effects in Hall et al. Validity – most advertisements are made of images and text; Burke and Srull only used text-based adverts. In Hall et al., participants may have spoken to other shoppers, which could have altered their behaviour. Interviews – face-to-face, self-report data can be affected by social desirability bias, reducing validity (Hall et al.); shoppers may not have voiced concerns as they did not wish to be ‘uncooperative.’ Reliability – noise and crowding may have varied across the 180 trials in Hall et al.; lack of standardisation limits replicability. Issues and debates Individual and situational explanations In Hall et al. (2010), only half the sample showed choice blindness when products were dissimilar. This phenomenon may be affected by personality (individual factor). The similarity of the paired products and free gift offer (situational factor) elicited more choice blindness. Determinism versus free will The dual processing model is deterministic; purchasing decisions are affected by automatic unconscious System 1 thinking. Likewise, ignoring available information and failure to think rationally (System 2) suggests behaviour is less affected by free will than we might think. Hall et al. (2010) demonstrated that sometimes behaviour/cognitive processing is determined by factors outside of our awareness. Unless we force ourselves to pay conscious attention to sensory experiences, cognitive capacity may be diverted to other tasks. STUDY TIP What would be the best way to analyse the data in Hall et al. (2010)? Refresh your memory of descriptive statistics on page 82, if you need to. Asking questions like this every time you look at a piece of research will help you to remember the details better, consolidate key research methods terminology and prepare for ‘Plan a study’ questions.

Beliefs and expectations Research shows that blankets in opaque boxes with ribbons were rated as more likely to be expensive and pristine than the same blankets in boxes with transparent windows. Friends appreciate poorly wrapped presents more than neatly wrapped presents. Rixom et al. (2019) explains this using expectation disconfirmation: » Poor wrapping = low expectations, so the gift is a pleasant surprise even if it is not something the recipient would have chosen (blankets, etc.). » Recipients prefer gifts from acquaintances to be neatly wrapped; this is an indicator of the value placed on the relationship (friends, etc.). STUDY TIP Drawing appropriately labelled graphs can help you to remember the direction of any differences in study findings (e.g. the shape of the pot with the best-tasting yoghurt in Becker et al., 2011). Even if you do not have the data (e.g. percentages, means, etc.) to plot the graphs accurately, you can still show which bar is taller/shorter, or plot the points on a scatter graph to show a strong or weak positive or negative correlation. Sketching graphs in this way is useful for your revision, especially if you make them colourful/distinctive and re-visit your images regularly. Key study: Becker et al. (2011) Context: » Packaging is important when consumers’ brand/product awareness is limited or there is time pressure. » Colour, shape and materials create expectations about quality, healthiness and/or taste. Packaging shape and colour: » Cross-modal correspondence may affect how we experience a product – for example, the brighter green the can, the more intense the lemon flavour. » Processing fluency and congruence: mismatched shapes and colours (e.g. rounded shapes in bright/high saturation colours) are incongruent – they have low processing fluency (see Table 7.34). » Individual differences: design-sensitive individuals are more likely to experience the positive effects of cross-modal correspondence and the negative effects of incongruence. 160 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 160 14/08/23 7:19 PM 7 Consumer Psychology ▼ Table 7.34 Processing fluency and congruence of shapes and colours Shape Colour saturation High Low Rounded Incongruent; low fluency; negative emotion Congruent; high fluency; positive emotion Angular Congruent; high fluency; positive emotion Incongruent; low fluency; negative emotion Aim and hypotheses: » Aim: to investigate the effect of packaging colour/shape on taste. » Hypotheses: 1 Yoghurt in angular pots will have a stronger flavour than the same yoghurt in rounded pots. 2 Yoghurt in high colour-saturation pots will have a stronger flavour than the same yoghurt in low colour-saturation pots. 3 Attitudes will be more positive for yoghurts in congruent pots (e.g. angular shape and high colour saturation) than in incongruent pots. 4 Colour and shape congruence will have a greater effect on yoghurt flavour for highly design-sensitive consumers than consumers with low design sensitivity. Research method(s) and design: » Research method: field experiment. » Design: independent measures. » Data collection technique: self-report questionnaire. Variables: Independent variables: » Differences in the yoghurt packaging – colour saturation – high versus low – shape angularity – angular versus rounded » design sensitivity – higher versus lower than the median on the ‘Individual Differences in the Centrality of Visual Product Aesthetics’ scale (Bloch et al., 2003); 11 items, rated 1–7. Dependent variables: rated from 1 to 7 (‘not at all’ to ‘very much so’) on: » taste intensity (e.g. sharp, bitter, mild) » product evaluation (e.g. superior, eye-catching, high-quality) » price expectation (in Euro cents). Sample: » Size: 151. » Demographics: German supermarket customers; 77 female, 74 male; mean age: 31. » Sampling technique: opportunity sampling; customers asked to participate in a ‘taste test’. Procedure: » Pre-test: participants rated pairs of pots; those that differed most were selected for the design of the pots in the main study. » Main study: shoppers watched a 20-second video of one of the four pots rotating. » Next, they tasted a lemon yoghurt; all samples were the same. » Finally, they completed an online questionnaire. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 161 161 14/08/23 7:19 PM Controlled variables: all participants: » tasted the same lemon yoghurt, regardless of shape/colour of the pot » watched the same duration of video clip (20 seconds) and the pots all rotated in the same way » answered the same structured questionnaire after watching the video. Ethics: » Deception: participants thought they were taking part in a yoghurt ‘taste test’. They did not know that they were all tasting the same yoghurt. » They were told that the design sensitivity questionnaire was about ‘customer lifestyle profiling’. » Deception reduced demand characteristics and risk of harm was low. Results: » There was no difference in taste intensity between packaging that was: – angular and rounded – high and low colour saturation. » The high (but not low) design sensitivity group rated the yoghurt in the angular pot as more intensely flavoured than the yoghurt in the rounded pot. » Angular pots were rated more positively and the suggested price was higher than the rounded pots. This effect was mediated by potency – that is, angular pots were perceived as more impressive (potent) and hence more expensive. » Price was marginally higher for the low colour saturation pots than the high colour saturation pots. Conclusion: angular packaging increases taste intensity but only in people who are sensitive to design, providing some support for cross-modal correspondence. Attention and shelf position Shoppers typically select central item(s) in a horizontal display; consumer psychologists call this horizontal centrality. For example, products displayed in the middle of a shelf were found to be chosen 71 per cent of the time. SKILLS BUILDER From the key study by Becker et al. (2011) on food package design and taste perception, explain how participants were allocated to the high and low design sensitivity groups. [4] Think about how you could break down the information. For example, you could mention the questionnaire that the participants had to complete, how the items were rated, how the researchers calculated participant scores and finally how the researchers calculated the median and split the participants into those who scored over or under the median. The use of eye-tracking Also see page 145. » This is an objective technique for investigating visual attention – for example, gaze location and duration of fixations and saccades. » Data can be used to create heat maps (digital representations of how shoppers scan shelves) (e.g. see Figure 7.2). Relevant research: Atalay et al. (2012) Aim: to investigate the effect of horizontal centrality on choice likelihood and how it is linked to increased visual attention and/or inferences. Methodology: ▲ Figure 7.2 Eye-tracking technology can provide a ‘heat map’ style representation of the visual field, showing the areas that attract the most visual attention » Sixty-three students viewed two planograms for as long as necessary to select a product. » Eye-trackers monitored gaze location and duration as participants made their choice. » Attitudes towards different brands were measured via a questionnaire. Results: » The average time taken to select a product was 35 seconds. » Horizontally central brands attracted greater visual attention specifically during the first 0.5 seconds and the last 5 seconds before selecting a product. » Centrally located products were selected 18 per cent more often than those at the sides. 162 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 162 14/08/23 7:19 PM 7 Consumer Psychology Conclusions: horizontal centrality and central gaze cascade effect are supported. Centrally located brands attract more attention and are chosen more frequently. SKILLS BUILDER Explain one weakness of research into packaging and positioning from the holism side of the reductionism versus holism debate. [2] Try focusing your answer on a problem with either Becker et al. (2011) or Atalay et al. (2012) that can be related to holism. Think about types of data (e.g. quantitative), then think about what was being measured, such as attitudes towards the taste of a yoghurt in Becker et al. Was the data collected reductionist? Was it more or less so than Atalay et al., who measured gaze location and duration of fixations while looking at a planogram? Once you have thought about this, you are ready to think about a weakness of the research. The command term ‘explain’ means you need to state your weakness and say why it is a weakness. ▼ Table 7.35 Methodological issues Strengths Weaknesses Validity – both studies have strong internal validity. Atalay et al. (2012) controlled brand names, background colour and readability. Becker et al. (2011) designed the pots based on a pre-test to ensure the independent variable was valid. Validity – choosing a product from a planogram is not the same as choosing from a real or online store (Atalay et al.). Becker et al. only tested lemon yoghurt; findings may not be the same for other foods with different textures or flavours. Objectivity – eye-tracking data is objective and provides quantitative data that can be statistically analysed (Atalay et al.). Manipulation of ‘design sensitivity’ should be objective (Becker et al.); scores were collected using a psychometric test and median-split used to create two groups. Generalisations – older consumers in real-life settings may not favour centrally placed items to the same extent (Atalay et al.). Becker et al. only sampled German shoppers. Issues and debates Reductionism versus holism Consumer decisions may be based on other factors besides shelf location and packaging. Individual differences such as brand knowledge and recommendations, and situational factors such as time pressure and crowding may also be involved. Investigating interactions between factors could provide more valid predictions. Determinism versus free will Consumers may be unaware of the extent to which shelf location and packaging determines purchasing. The findings of these studies may encourage consumers to exercise free will when making decisions, especially ones that affect finances and health. SKILLS BUILDER a Describe what psychologists have discovered about packaging and positioning of a product. [6] b Evaluate what psychologists have discovered about packaging and positioning of a product, including a discussion about generalisation from findings. [10] The key terms ‘packaging’ and ‘positioning’ tell you that this essay should include information about the studies by Becker et al. (2011) and Atalay et al. (2012). But what exactly is meant by ‘what psychologists have discovered about … ‘? Discoveries are basically the findings of research studies, so the way variables are related or affect one another (or not, as the case may be). In part a, you could write about processing fluency and crossmodal correspondence in relation to Becker et al. Next, you could write about horizontal centrality in relation to Atalay et al.

Experts provide individualised services and use active listening to understand customer problems. Increases cooperation, trust and repeat trade; decreases conflict. Salespeople who ask too many questions can be seen as poorly informed. Competitor Customers have similar needs. Salesperson tries to show the customer how they are similar to other satisfied customers; features, advantages and benefits (FAB) are emphasised and compared with rival brands. Decreased customer satisfaction compared with customer-focused. Buyers show greater negotiation/ bargaining; negative impact on developing relationships. Too many comparisons with rival brands can be seen as a sign of incompetence. Product Customers are fairly passive; little information is shared as they are asked few questions. Salesperson convinces/ persuades buyers that they need the product; detailed product information and demonstrations are provided; no comparison with rival brands. Buyers perceive sellers as experts, increasing trust and promoting positive relationships. SKILLS BUILDER a Describe what psychologists have discovered about selling the product. [6] b Evaluate what psychologists have discovered about selling the product, including a discussion about field experiments. [10] In part b, a popular strategy is to evaluate the methodology of the research studies used in part a. However, this section of the syllabus only includes one piece of research (an example of DTR; Kardes et al., 2007). The research by DelVecchio et al. (2003) could cue you to discuss issues such as objectivity and generalisations. Remember, you don’t always have to know researchers’ names to use their studies, as long as the study is recognisable and relevant. . 164 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 164 14/08/23 7:19 PM 7 Consumer Psychology Interpersonal influence techniques Kardes et al. (2007) investigated the disrupt-then-reframe (DTR) technique at a supermarket. ▼ Table 7.37 The DTR technique Selling technique Percentage of shoppers who bought candy Control condition: ‘The price is now 1 Euro. It’s a bargain!’ 44% Disrupt-then-reframe: ‘The price is now 100 Euro cents’ (‘disrupt’), ‘That’s 1 Euro. It’s a bargain!’ (‘then reframe’) 65% The need for cognitive closure and ambiguity aversion » Humans are ambiguity averse; cognitive closure is sought through quick, simple solutions. » Some people have higher need for cognitive closure (NFCC) than others. » The disrupt-then-reframe (DTR) technique is more effective with people who have high NFCC. » Reframing resolves ambiguity created through disruption. Relevant research: Kardes et al. (2007) Aim: to investigate the effect of NFCC on the effectiveness of the DTR technique. Methodology: a confederate selling club membership to students said either, ‘You can now become a member for half a year for 3 Euros. That’s a really small investment!’ or, ‘You can now become a member for half a year for 300 Euro cents’, followed by, ‘That’s 3 Euros. That’s a really small investment!’ (DTR group). Students completed a NFCC questionnaire. Results: ▼ Table 7.38 Percentage of DTR and control groups who paid for membership Percentage of the group who paid for membership DTR Control 30% 13% Buyers in the DTR group were more likely to have high NFCC than buyers in the control group. Conclusions: DTR increases compliance but this is moderated by need for cognitive closure. NFCC increases when: » time is short » the situation is boring » the individual is from a high uncertainty avoidance culture (e.g. Japan). Cialdini’s six ways to close a sale SKILLS BUILDER The disrupt-then reframe technique is affected by the need for cognitive closure. Outline one or more factors that affect the need for cognitive closure. [4] The stem mentions the DTR technique and NFCC, so you might decide to define these terms and/or explain how they are related, but be careful – this is not what is required. The key words are ‘factors that affect’. How do cultural differences or time pressure affect NFCC? ▼ Table 7.39 Six ways to close a sale Way to close a sale Description Example(s) Reciprocation Humans have a tendency to return favours. The salesperson ‘helps’ us by giving a discount; we feel indebted to them and obliged to buy the item. Commitment and consistency Humans prefer/expect others to behave consistently. If a person commits to doing a job at a certain price, we expect them to stick to this. Social proof Consumers ‘look to’ others as a guide to how to behave, especially people they admire. Influencers on social media platforms such as TikTok and Instagram can influence how we behave. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 165 165 14/08/23 7:19 PM Way to close a sale Description Example(s) Authority People are more likely to buy from people with authority (e.g. expertise, charisma). Celebrities with connections to products are used in adverts, such as sports personalities selling vitamin supplements. Liking Sales are more likely when there is good rapport between seller and potential buyer. ‘Chuggers’ seeking charitable donations from passers-by often pay compliments in an attempt to build a relationship. Scarcity Rare products/services automatically become more valuable. Shops often state that ‘stocks are limited’ or that ‘special offers’ will not be available after a certain date. Research evidence Support for reciprocity: when given a free gift, participants rated a company more favourably than participants who did not receive a gift (Beltramini, 1992). However, gift recipients were no more likely to contact the company in future; gifts improved attitudes but not sales. ▼ Table 7.40 Methodological issues Strengths Weaknesses Validity – Beltramini (1992) has high ecological validity as it was conducted in genuine business settings. In Kardes et al. (2007), students were unaware of their participation, decreasing demand characteristics. Field experiment – students in Kardes et al. (2007) were unaware of their participation so could not consent or withdraw. They were told the NFCC questionnaire was about ‘lifestyles and opinions’. Objectivity – DelVecchio et al. (2003) measured buyerresponsiveness, which is a more objective measure than self-reports from salespeople, which can be biased and subjective. In Kardes et al., NFCC was measured using sixpoint scales; quantitative data analysis is more objective than qualitative. Generalisations – in DelVecchio et al. the sample was 85 per cent men (androcentric); this is not representative of how female buyers/sellers interact. All students in Kardes et al. studied at a Dutch university. Issues and debates Applications to everyday life Selling strategies can be tailored for different-sized organisations that respond differently to various techniques, based on evidence. DTR can be used to help organisations to increase sales, including not-for-profit organisations. Cultural differences Buyers in uncertainty avoidance cultures may respond more positively to productfocused selling techniques. Social proof is more effective than commitment/ consistency in uncertainty avoidance cultures. Determinism versus free will NFCC is partly determined by time pressure but low NFCC customers may exercise free will when there is no time pressure. This makes purchasing difficult to predict. SKILLS BUILDER Jalita is the top seller on Me2U, a home shopping channel. She sells everything from bedding to blenders, often shifting thousands of units in minutes. Plan a case study to investigate the sales techniques Jalita uses and why she is so successful. [10] 166 Remember, case studies involve triangulation, so you will need to think of at least two ways in which data could be collected about Jalita’s selling techniques. Also, think carefully about how you will ensure these data-collecting methods are valid and reliable (revisit page 80, if you need to).

[4] 7.4.3 Buying the product The Engel-Kollat-Blackwell model This five-stage model takes an information processing approach to understanding buying behaviour. ▼ Table 7.41 The five stages of the Engel-Kollat-Blackwell model Stage Description Input Attention may or may not be paid to incoming information (stimuli) about brand, price and/or company identity. Information processing If attention is paid, further processing begins; determined by cognitive style and life experiences. Decision-making To make a purchase, consumers must identify/recognise a need for a product; a product search begins, alternatives are compared and evaluated. Decision process variables Internal (dispositional) factors affect decision-making – for example, beliefs, values, attitudes, personality and lifestyle. External factors External factors affect decision-making, such as family and cultural norms. STUDY TIP There are some small but important parts of the syllabus in this section that could be easily missed, such as factors that increase or reduce dissonance. Keep a copy of the relevant syllabus section at the front of each set of revision notes. This will help you familiarise yourself with the exact wording/ phrasing of the content. Purchase(s) may or may not be made following each of the five stages. Finally, consumers feel satisfaction/pleasure or dissatisfaction/cognitive dissonance. Deciding where to buy ▼ Table 7.42 Factors affecting store choice Type of factor Examples Situational factors Aspects of the store Accessibility, convenience, price, quality Purpose of shopping trip Weekly food shop, buying gifts, browsing Individual differences Beliefs, values and attitudes Sustainability versus price Personality Need for personal gratification (see Sinha et al., 2002 below) Age Older consumers are more likely to shop for recreation/pleasure than younger shoppers Relevant research: Sinha et al. (2002) Aim: to investigate reasons for store preferences. Methodology: shoppers are asked to complete Likert-scale items and one open question (give three reasons for store choice) as they leave shops, in Ahmedabad, India. Results: over 70 per cent stated convenience and product range but these reasons differed by age, gender and store type. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 167 167 14/08/23 7:19 PM ▼ Table 7.43 Reasons for store preference by age, gender and store type Convenience Product range Age Least common in under 20s and over 50s Common in 25–40-year-olds Gender More common in males than females (40 per cent versus 30 per cent) More common in females than males (40 per cent versus 30 per cent) Store type Consumables (e.g. groceries) Non-consumables (e.g. clothing) Other common reasons included: » service: common in 30–40-year-olds » ambience: important to those aged 25–40, and males more than females » previous patronage: more common in females than males. Females spent more time considering alternatives than males. Conclusions: store choice is determined by multiple factors, including age and gender of shoppers. SKILLS BUILDER Yaakov and his daughter Verusha are shopping in a wealthy area. They do not always want to go into the same types of store. Outline one or more reasons to explain why Yaakov and Verusha prefer different types of store. Refer to psychological research in your answer. [2] Review the study by Sinha et al. (2002). What would they have to say about Verusha (the daughter) and Yaakov (the father) regarding the shops they might like to visit? Use Table 7.43 to guide you. There are just three minutes for this question – focus on just one reason (e.g. gender) to avoid running out of time. Post-purchase cognitive dissonance ▼ Table 7.44 Factors that increase dissonance Factor Description Commitment Stronger values/beliefs lead to greater post-purchase dissonance when behaviour is inconsistent. Involvement Greater time/effort (high involvement) invested at product search stage leads to greater dissonance. However, dissonance may also result from impulse purchases (low involvement). Culture and religion Purchasing products that are prohibited by some cultures yet highly desirable in others may increase dissonance. ▼ Table 7.45 Ways of reducing post-purchase dissonance Strategies for decreasing dissonance Description Adaptive preference formation Exaggerating positive features of purchased items; reconstructing memory of alternatives to make them seem less desirable. Social proof Reading reviews from other satisfied customers. Feedback Leaving positive reviews for online purchases. Relevant research: Nordvall (2014) Aim: to investigate dissonance and adaptive preference formation following purchase of low-involvement products. Methodology: » Students rated how often they purchased 25 unbranded organic and non-organic products. » Items with similar ratings were paired (each item was equally desirable). 168 SKILLS BUILDER Explain one way that post-purchase dissonance can be reduced. [2] Three ways to reduce dissonance are listed in Table 7.45. As this question asks you to ‘explain’ rather than ‘outline’, choose the way that you feel most confident about, in terms of how and why it helps to reduce dissonance. For example, leaving feedback means the buyer will have to articulate why they particularly liked the product they have bought. You could link this to adaptive preference formation as an explanation of how dissonance can be resolved. Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 168 14/08/23 7:19 PM 7 Consumer Psychology » Dissonance was created by asking participants to reject one item in each pair. » All 50 products were presented again with reminders about whether the products were accepted/rejected. » Participants re-evaluated each product and were asked to justify their decisions by choosing reasons from a list. Results: ▼ Table 7.46 Ratings for items and reasons for rejection Ratings Reasons Organic item rejected Increased for both products Price and appearance Organic items accepted Decreased for non-organic option Animal welfare and environmental concern Conclusions: » Cognitive dissonance also occurs with low-involvement purchases. » Adaptive preference formation as a way of resolving dissonance was supported. ▼ Table 7.47 Methodological issues Strengths Validity – online grocery shopping is common in Northern Europe, increasing validity of Nordvall (2014). In Sinha et al. (2002), shoppers were stopped as they exited stores; reasons are likely to be well remembered (more accurate). Objectivity – Sinha et al. used Likert scales; these do not require interpretation when analysed. Weaknesses Validity – shoppers did not rate or give reasons for online purchases; potential for demand characteristics and social desirability bias decrease validity. Subjectivity – although there is no interpretation required at the point of analysis, Likert statements (Sinha et al.) may be interpreted differently by individuals when they complete them, so could also be considered subjective. Issues and debates Application to everyday life Understanding reasons for rejecting organic products is important for increasing environmentally friendly behaviour. Cultural differences Nordvall et al. (2014) was conducted in Sweden, an individualist culture (consistency between values and behaviour is important). Post-purchase dissonance may be less common in collectivist cultures. Idiographic versus nomothetic Sinha et al. (2002) was mainly nomothetic. Consumers answered one open question compared with 43 closed questions. An idiographic approach might provide greater insight. Nordvall et al. (2014) was also more nomothetic (measured attitudes using Likert scales and asked people to select reasons from a predetermined list). Reasons for rejecting organic products may have been missed. Reductionism versus holism The Engel-Kollat-Blackwell model is holistic. It considers interactions, external stimuli, internal processes (e.g. memory, emotion) and social context. Buyers and their decisions are seen as unique. SKILLS BUILDER a Describe what psychologists have discovered about buying the product.

Your plan must include details about: – type of data – frequency of testing. [10] b For one piece of psychological knowledge on which your plan is based: i Describe this psychological knowledge. [4] ii Explain how you used two features of this psychological knowledge to plan your study. [4] 7.5 Advertising 7.5.1 Types of advertising and advertising techniques Advertising campaigns increase awareness of brands and products. They target key audiences whose attitudes and behaviour they hope to change. The Yale Model of Communication » Explains why some attempts to change attitudes are more effective than others. » Applies to many areas of psychology, such as health and consumer psychology. » Can be summarised as ‘who said what to whom?’. » Two more factors were added later: ‘how?’ and ‘to what effect?’ (McGuire, 1968). ▼ Table 7.48 The Yale Model of Communication The source » Credibility, expertise, authority, charisma, attractiveness and popularity » Audiences need to identify with the source The message » ‘Hard sell’ – product information, pros and cons of rival brands; repeated and explicit showcasing of the product » ‘Soft sell’ – subtle, subjective, uses imagery and positive associations with product; information provided about the target consumer’s identity/lifestyle » First and last messages are often the most effective The audience » Age, gender, cultural identity » Level of education » Self-esteem The medium/channel For example, television, radio, print, social media, product placement in films, billboards, etc. To what effect Receptivity/yielding are more likely if audience members: » pay attention » understand/accept the messages » are motivated. Research evidence » Celebrity endorsement improved perception of adverts in India (source credibility). » Over-exposure of celebrities who do not ‘match’ the brand leads to negative attitudes/reduced message clarity. 170 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 170 14/08/23 7:19 PM 7 Consumer Psychology SKILLS BUILDER Plan a laboratory experiment to investigate one aspect of the Yale Model of Communication in relation to advertising, (e.g. source, message). [10] Remember, laboratory experiments take place in controlled settings, which decrease ecological validity. To counteract this, can you think of ways of ensuring the task that participants have to complete has high mundane realism? This is important as you should always think about how the plan makes the study valid. Advertising media ▼ Table 7.49 Types of advertising media Type of advertising Strengths Weaknesses Print, such as newspapers and magazines adverts » Companies reach receptive consumers » Pages can be cluttered with rival through special interest magazines, increasing product credibility. » Less annoying than other types of advert (Elliott and Speck, 1998). brands, decreasing clarity. Television » Reaches huge audiences. » Stimulating and emotionally arousing » Television advertising is expensive. » On-demand streaming is replacing storylines build brand identity. traditional television viewing. » Website ‘cookies’ facilitate targeted Internet advertising. » Psychographic profiles are developed based on consumers’ online activity. » Adverts are shown selectively to consumers who match the product’s target demographic. Smartphones and social media » Purchasing decisions are affected by social media for 75 per cent of ‘Gen Z’, 48 per cent of ‘millennials’ and 68 per cent of ‘boomers’. » Trust, loyalty and brand identity are built through repeated exposure. » High-quality ‘user-generated content’ (UGC) can turn interest into purchasing intent. » Internet users ignore online adverts – for example, banner blindness. » People sometimes do not recognise adverts following online exposure. » Lack of transparency regarding relationship between influencers and brands leads to negative attitudes and decreases impact. Neuromarketing Neuromarketing is the use of physiological measures (e.g. EEG and eye-tracking) to measure responses to advertising, packaging and/or point of purchase displays, leading to evidence-based marketing. Relevant research: Ciceri et al. (2020) Aim: to investigate differences in brain activity, visual attention and recognition of print or digital adverts. Methodology: » Participants viewed a mock newspaper – in print online or on a desktop computer or tablet. » The location/duration of fixations were measured with eye-tracking. » Frustration was measured using EEG. » One hour later, participants were asked to select 25 adverts that were in the newspaper from a set of 50. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 171 171 14/08/23 7:19 PM Results: » The desktop group had the lowest average fixation and recognition. » The tablet group had the highest average fixation and recognition. » Frustration was the same for both digital groups. Conclusions: » Less attention is paid to website adverts than print (e.g. banner blindness). » Website adverts are less recognisable, suggesting less impact. Lauterborn’s 4Cs marketing mix model Lauterborn (1990) modified the outdated 4Ps model (McCarthy, 1960) (see Table 7.50). ▼ Table 7.50 Lauterborn’s 4Cs marketing mix model 4Ps model; seller-centric Product Price Place Promotion 4Cs marketing mix model; Explanation consumer-centric Customer wants and needs Customers are persuaded that they need/want the product Cost Delivery/travel expenses, guilt due to ethical concerns/cognitive dissonance Convenience Online shopping creates greater competition between sellers Communication Selling should involve cooperative communication, including feedback SKILLS BUILDER Indie sells organic sausages at farmers’ markets. He regularly sells out within the first two hours. Explain how Indie’s understanding of Lauterborn’s 4Cs marketing mix model may have helped him develop such a successful brand. [2] Start by searching for the part of the syllabus that is referenced – the 4Cs. Next, read again and work out what the question is really asking. Indie sells a lot of sausages, suggesting that he is a good salesman. How do the 4Cs link to Indie? Choose the one you think is the ‘best fit’ and that you can explain, not just describe. How and why have customer needs, convenience, cost or communication helped Indie to develop his brand? SKILLS BUILDER Compare the use of eye-tracking and EEG as ways of investigating advertising techniques. [4] ‘Compare’ requires you to think of similarities and differences; try to think of one of each. Each point should refer to both eye-tracking and EEG and use words like ‘whereas’ (differences) and ‘likewise’ (similarities) to connect the two parts of your point. Try starting your points with terms like ‘Alternatively’ and ‘In contrast’ (differences) or ‘Both’ (similarities). For example, ‘Both EEG and eye-tracking are objective ways of collecting data, for example … ‘. ▼ Table 7.51 Methodological issues Strengths Replicability – there was a standardised procedure in Ciceri et al. (2020) (e.g. screen luminance, angle, size and order of adverts). Objectivity – Ciceri et al. used EEG and eye-tracking data; measurements were not open to human error, bias, demand characteristics/social desirability bias as they measured unconscious processing. Weaknesses Validity – the Yale Model of Communication has low temporal validity; ecommerce, product placement, buyerto-buyer communication and influencers are not considered. It is also over-simplified and does not consider yielding in under-motivated audiences. Internal validity in Ciceri et al. is reduced due to confounding variables (e.g. differing screen sizes for tablet versus desktop). Generalisations – Ciceri et al. sampled only 24 participants per group; this may not be representative of all news readers. Issues and debates Applications to everyday life Lauterborn’s 4Cs marketing mix model sees buyers as diverse/active participants, whereas the 4Ps saw them as passive/homogenous. This encourages sellers to explore customers’ needs/wants. The findings from Ciceri et al. (2020) could inform budgeting decisions regarding investment in print versus digital marketing. 172 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 172 14/08/23 7:19 PM 7 Consumer Psychology Cultural differences Ciceri et al.’s (2020) participants were Italian, so the study needs to be replicated in other cultures.

More effective with low self-monitors. Explanation High self-monitors: concerned with the image they project to others; soft sell focuses on this. Low self-monitors: behaviour is consistent with their values, regardless of others; hard sell helps them to determine if a product meets their needs. Aim and hypotheses: » Aim: to investigate the relationship between self-monitoring and imageoriented/soft sell versus quality-oriented/hard sell advertising. » Hypotheses: 1 High self-monitors are more likely to try new shampoo when image-oriented (soft) selling is used compared with quality-oriented (hard) selling. 2 Low self-monitors are more likely to try new shampoo when quality-oriented (hard) selling is used compared with image-oriented (soft) selling.

Controlled variables: » The telephone call was scripted/standardised; controlled for tone of voice, gender of caller. » Random allocation reduced participant variables, such as interest in hair care products. Ethics: deception – participants were told the telephone call was market research, which was not true; there was no informed consent or right to withdraw; participants may be mistrustful of future legitimate calls. Results: » Image-oriented messages = higher willingness to use for high compared with low self-monitors. » Quality-oriented messages = higher willingness to use for low compared with high self-monitors. Conclusion: responsiveness to hard and soft sell is dependent on the consumer’s level of self-monitoring. STUDY TIP Think carefully about the named research method in ‘Plan a study’ questions like 7.56 at the end of this section. You need to consider the type of data that will be produced and how it can be analysed. For example, qualitative interview data can be turned into quantitative data by counting the frequency of certain themes. Then data from high and low self-monitors could be compared. You might show different types of adverts and ask your participants about them, but what will you ask, how and why? SKILLS BUILDER a Describe the study by Snyder and DeBono (1985) on consumer personality and advertising. [6] b Evaluate the study by Snyder and DeBono (1985), including a discussion about self-reports. [10] Complex procedures can be difficult to summarise in nine minutes and this requires lots of practice. The word GRAVE (generalisations, reliability, applications, validity and ethics) can be helpful for remembering different ways of evaluating studies. You do not need to cover all of these concepts though; fewer, fully elaborated ideas are a better way to increase your grade. Effect of product placement in films on choice ▼ Table 7.53 Possible explanations for the effects of product placement Explanation Description Evaluation Mere exposure » Repeated exposure increases positive Product placement (without reminders or later product recognition) increased positive attitudes (Ruggieri and Boca, 2013); this supports implicit memory. Cultural differences: purchase intention increased more for US than French or Austrian participants following mere exposure to product in a film (Gould et al., 2000). attitudes. » Product exposure in films/television increases familiarity and positivity. Reminders » Familiarity (through repeated viewing) Auty and Lewis (2004); see below. increases product familiarity/liking. » Familiar stimuli are easier to process (processing fluency); this increases positive emotion. Relevant research: Auty and Lewis (2004) Aim: to investigate the effect of product placement on children. Methodology: » Six to twelve-year-olds watched a clip of Home Alone (a popular children’s film) featuring either: – pizza and Pepsi, or – macaroni and milk. 174 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 174 14/08/23 7:19 PM 7 Consumer Psychology » They were interviewed about the clip and asked to name the cola brand if they did not mention it spontaneously. » They were then offered Pepsi or Coca-Cola. Results: ▼ Table 7.54 Percentage selecting Pepsi following the interview Chose Pepsi ‘Pepsi’ group 62% ‘Milk’ group 38% ▼ Table 7.55 Percentage naming Pepsi when prompted Age Percentage who named Pepsi when prompted Number of prompts required 6–7 50% 4.4 11–12 67% 2.1 Younger children: » needed more prompts to recall brand names » were as likely as older children to select Pepsi over Coca-Cola. Children who had seen the film before were more likely to: » recall the cola brand without prompting » choose Pepsi over Coca-Cola. Conclusions: » Viewing products on film increases the probability that the product is chosen in future (implicit memory). » Product placement is more effective following repeated exposures (reminders effect). ▼ Table 7.56 Methodological issues Strengths Weaknesses Validity – Snyder and DeBono (1985) used a double-blind design (researchers did not know whether the students were high or low self-monitors). Auty and Lewis (2004) randomly allocated children to the milk or Pepsi groups to control for participant variables. Validity – in Auty and Lewis, prior drink preference (Coca-Cola or Pepsi) was a possible confounding variable. Also, the children may have thought they were meant to choose Pepsi as they were asked about it in the interview. Quantitative data – both studies used quantitative data, Self-reports – in Snyder and DeBono, people may have such as counting drink choices and measuring willingness given socially desirable answers to telephone researchers; to try a new shampoo, so data was more objective. this may not match actual purchasing and trial of new products. Issues and debates Determinism versus free will Responses to advertisements may be difficult to determine. Self-monitoring changes between situations. Matching advertising style to personality may increase product engagement but predicting purchasing behaviour is difficult. Application to everyday life Soft/hard sell does not work for everyone. Different campaigns could be targeted at different subgroups within the target audience. Benefits to society include banning product placement in children’s films and high-sugar products in UK films. Use of children in research Children did not know their drink selections were being observed. This could be seen as unethical, even with parental consent. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 175 175 14/08/23 7:19 PM SKILLS BUILDER With reference to product placement, explain one weakness of mere exposure as an explanation for choices. [2] When revising explanations, theories or models, make sure you can give at least two strengths and weaknesses. These should refer to issues and debates, research evidence, applications to everyday life and how the named explanation (e.g. mere exposure) compares with alternative explanations (e.g. reminders). In this question, think about the findings of Auty and Lewis (2004). What do they tell us about mere exposure explanation? NOW TEST YOURSELF 7.53 In Snyder and DeBono’s (1985) study, participants were split into two groups: high and low self-monitors.

Fans have noticed that the main character, Sylvester, chews this brand of gum in multiple episodes. Describe one explanation for the increase in sales of Rotter’s gum. [4] 7.55The Self-Monitoring Scale is a psychometric test designed by Snyder (1974) and used in his experiment on quality versus image-oriented advertising (Snyder and DeBono, 1985). Explain one way that reliability of psychometric tests such as the Self-Monitoring Scale can be tested. [2] 7.56Research suggests that different types of advertising suit different types of people – for example, high versus low self-monitors. a Plan a study using questionnaires to investigate attitudes towards television advertisements. Your plan must include: – question format (open and closed questions) with examples – ethical issues. [10] b iState one or more ways that you will increase the validity of your questionnaire data.

Relevant research: Fischer et al. (1991) Aim: to investigate logo recognition in children aged three to six years old. Methodology: » Three- to six-year-olds matched 22 logos to pictures on a board, including logos for products targeted at children (e.g. Cheerios, Disney) and adults (e.g. IBM computers, Camel cigarettes). » Parents reported on smoking, television habits and children’s requests for branded products. Results: » Six-year-olds easily recognised logos targeted at children and adults. » Three-year-olds were better at recognising logos targeted at children. 176 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 176 14/08/23 7:19 PM 7 Consumer Psychology ▼ Table 7.57 Percentage of children recognising logos targeted at children and adults Brand target audience Logo recognised Percentage of sample Children TV channel (Disney) 91% Cereal (Cheerios) 25.3% Car (Chevrolet) 54.1% Computer (IBM) 16.2% Adult ▼ Table 7.58 Percentage of children recognising the Camel cigarettes logo Age of children Percentage who recognised Joe the Camel regardless of family smoking habits Three-year-olds 30% Six-year-olds 91.3% Conclusions: » Children recognise brand logos targeted at adults and children. » Exposure to cigarette advertising may lead to serious future health risks. Brand awareness and image » Brand awareness involves product familiarity and understanding what differentiates the product from competitors. » Consumers are more likely to purchase familiar brands due to the availability heuristic (see page 153). » Branding should convey information about potential gains associated with the product. Effective slogans Slogans should help to: » maintain and enhance brand awareness » create, support or modify brand image » prime consumers to buy the product by increasing familiarity and liking. Unlike brand names/logos, slogans are updated often to attract new target consumers and increase market value. Changes suggest new marketing strategies and improved knowledge of target consumers. SKILLS BUILDER a Describe what psychologists have discovered about brand awareness and recognition. [6] b Evaluate what psychologists have discovered about brand awareness and recognition, including a discussion about applications to everyday life. [10] Using appropriate psychological terminology in your writing is a key skill. You don’t need to define every term; just try to use the right terms in the right places. Test your understanding of key vocabulary regularly using flashcards to help with this. Using key terms in conversation will also help you to transfer them to your written work. Types of slogans Effective slogans are stored in long-term memory; they are easily retrievable/ accessible. ▼ Table 7.59 Types of slogans Type of slogan Description Example Polysemous Multiple meanings; appealing to multiple target consumers Nike (sportswear): ‘Just do it’ Business Provide information about the company’s values Zara (clothing): ‘Love your curves’ Descriptive Create visual imagery Cadbury’s Dairy Milk (chocolate bar): ‘A glass and a half in every bar’ Persuasive Attempt to change consumer behaviour Nestlé (chocolate bar): ‘Have a break, have a KitKat’ Creative Word play/humour increase memorability Tide (laundry detergent): ‘Tide’s in. Dirt’s out’ Emotive Trigger an emotional reaction Tesco (supermarket): ‘Every little helps’ Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 177 177 14/08/23 7:19 PM SKILLS BUILDER Sure Smile toothpaste is one of the best-selling toothpaste brands on the market, but the new company director has decided she wants to update their logo and change the slogan. Outline one advantage and one disadvantage of these changes. [2] Under ‘Effective slogans’ above is an explanation of how changing slogans can increase market value (an advantage) and a brief reason for this. You may need to think a bit more about the disadvantages of changing the slogan or logo. How could you link this to brand recognition/awareness, similarity to competitors or processing fluency? Relevant research: Kohli et al. (2007) Aim: to develop guidelines for creating effective advertising slogans. Procedure: literature review. Researchers summarised and evaluated research on slogan design following a search for articles in academic and business journals. Results: guidelines were proposed based on findings of the literature review (see Table 7.60). ▼ Table 7.60 Guidelines for creating effective slogans Keep your eye on the horizon Avoid language that could become dated (keep it ‘timeless’). Every slogan is a brand positioning tool Emphasise the brand’s unique selling point (USP) – its benefits compared to rival brands. Link the slogan to the brand Include slogans on packaging and in advertising. Please repeat that Repeat the slogan in different advertising campaigns to increase memorability. Jingle, jangle Use music to increase memorability (take care, music can distract from the message). Use slogans at the outset Use as soon as a product comes to market; makes brand identity easier to establish. It’s OK to be creative Complex/ambiguous slogans that require deeper processing increases memorability. Conclusions: these guidelines should help businesses to develop effective slogans that: » are memorable » match existing brand perception » highlight differences between the brand and its competitors. STUDY TIP Using Table 7.60 for inspiration, create a set of correlational hypotheses to help you to remember the features of effective slogans. Remember, with correlational hypotheses, you are not stating that there will be a difference between two groups or conditions; you are saying that there will be a relationship/association between two measured variables. For example, ‘There will be a positive correlation between the number of times a slogan is used in a radio advert and free recall of the slogan three weeks later.’ ▼ Table 7.61 Methodological issues 178 Strengths Weaknesses Validity – Kohli et al. (2007) used real slogans from real businesses (e.g. BMW, Nike), not purely academic studies. In Fischer et al. (1991), the brand recognition test was age-appropriate, so unlikely to be affected by language skills, speaking or reading. Temporal validity – some of the slogans in Kohli et al. were from the 1960s; guidance may lack relevance to modern advertising. Experiments – standardised procedure in Fischer et al. allowed researchers to measure logo recognition reliably using a picture-matching task. Objectivity – Fischer et al.’s research was funded by Doctors Ought to Care and the American Cancer Society; this could lead to experimenter bias.

(1991) used young children, who are very receptive to social cues from adults. This may decrease validity. Determinism versus free will Research into logos and slogans may have helped change smoking and other unhealthy behaviours. However, individuals retain the ability to choose whether to smoke or quit, or to engage in other unhealthy consumer behaviours (e.g. gambling). Application to everyday life Guidelines have been designed to be used by businesses to increase sales through creating brand identity and improving brand awareness.

Argyle (1975) suggested that non-verbal communication is four times more powerful than verbal, but that it should match verbal communication. For example, trust is lost if a practitioner tells a patient there is nothing to worry about, but has an anxious facial expression. Types of non-verbal communication » Facial expression: patients may look at their practitioner’s face for clues about their diagnosis. Practitioners may use facial expressions to interpret how a patient is feeling about a diagnosis (Silverman and Kinnersley, 2010). » Paralanguage: non-verbal parts of speech, including ‘ums and ers’, volume, speed and pitch. Voice tone can indicate to patients that the practitioner is uninterested in them (Marcinowicz et al., 2010). » Personal space: practitioners often invade their patients’ personal space to examine them, making patients feel uncomfortable. Patients reporting greater invasion of their personal space were those who had more privacy at home and were lonelier (Marin et al., 2018). » Gestures: these can accompany verbal/non-verbal communication to help the patient’s understanding. However, they must be used cautiously. What might be acceptable in one culture may be considered rude in another. » Appearance: the practitioner’s physical appearance (clothes and hair) can affect a patient’s confidence in them. STUDY TIP When revising lists of factors, like the types of non-verbal communication, try making a ‘sentence story’ to help your memory: paralanguage, appearance, gestures, facial expression and personal space can become, ‘Without speaking (non-verbal), a parachutist with a nervous appearance gestured to the pilot and jumped into space with a surprised facial expression.’ Try writing the sentence on one side of a card and the list on the other and see if your friends can guess the factors. Relevant research: McKinstry and Wang (1991) Aim: to investigate whether doctors’ clothing influenced patients’ respect for them and how acceptable patients found different clothing styles. Methodology: » Involved 475 patients of 30 doctors from five Scottish practices. » Questionnaire was administered on five separate occasions: – five photos of male doctor – white coat, suit, tweed jacket, cardigan or jeans – three photos of female doctor – white coat, skirt or trousers. » Participants were asked: – which doctor they would feel happiest about seeing for the first time – their level of confidence in the doctor – which photo looked most like their own doctor – about clothes worn in the photos. Results: ▼ Table 8.1 Percentage of top acceptability score (5) for the doctors in the different styles of clothes Percentage of patients Male doctor Female doctor Acceptability score White coat Suit Tweed jacket Cardigan Jeans White coat Skirt Trousers 5 38% 50% 30% 16% 13% 55% 47% 22% Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 181 181 14/08/23 7:19 PM » There was a significant relationship between patient age and doctor choice. » Older patients gave higher scores to the male doctor in a suit and white coat and the female doctor in a white coat. » Some voted in a way that matched the clothing choice of their own doctor. » Clothing style was very important/quite important for 64 per cent of participants, and not important to 36 per cent. Conclusion: patients prefer conservatively dressed doctors. The researchers concluded that doctors may dress in a certain way to gain patients’ approval. Verbal communication Verbal communication focuses on how the practitioner questions the patient about their condition and conveys information about diagnosis and treatment. Factors affecting verbal communication » Primacy effect: information from the beginning of the consultation is stored in long-term memory and remembered better than later information (Ley, 1988). » Forgetting: patients often remember little of their doctor’s consultations. Richard et al. (2016) reported patients remembering as little as 20 per cent of information and immediately forgetting between 40 and 80 per cent. Recently, attention has turned to how practitioners communicate using medical terminology. Relevant research: McKinlay (1975) Aim: to investigate Scottish working class families’ understanding of medical terminology. Methodology: » Participants were 87 unskilled working-class women attending obstetrics and gynaecology appointments. » They were split into utilisers and underutilisers. » Participants were presented with a 13-word list used by practitioners when speaking to patients: – Words were spoken aloud. – They were heard again in a sentence. – Participants were asked to say their meaning. – Responses were recorded verbatim and scored (‘blind’) in categories, as shown below. SKILLS BUILDER Mark is a newly qualified doctor in a small clinic in a village with a large population of elderly people. Suggest one way that Mark could dress, and one action that he could take, to instil confidence in his patients. [4] Try to include research evidence in your answer. For example, McKinstry and Wang (1991) looked at how clothing style can inspire confidence in patients. Argyle (1975) and Silverman and Kinnersley (2010) investigated non-verbal communication.

SKILLS BUILDER Using research into practitioner–patient communication, explain one weakness of quantitative data. Use an example from research into practitioner–patient communication. [2] This question tests methodological knowledge and can be answered using research into verbal or non-verbal communication. ▼ Table 8.4 Methodological issues Strengths Weaknesses Validity – McKinstry and Wang (1991) used photographs of unknown doctors rather than asking participants to talk about their own doctors. McKinlay (1975) interviewed patients at the clinic about words they would hear there. Understanding of these words represents their real-life understanding. Generalisability – McKinstry and Wang’s sample, from Lothian in Scotland, may not be representative of other areas. McKinlay’s participants were working-class women. Including patients with a wider range of conditions and from a wider range of backgrounds would increase generalisability. Usefulness – McKinlay’s results may be used in healthcare Quantitative data – McKinlay’s data showed settings to address miscommunication and improve underutilisers generally had poorer technical vocabulary; understanding between practitioners and patients. qualitative interview data is needed to discover why. Questionnaires – McKinstry and Wang included quantitative data reliably obtained from closed questions. Validity – McKinstry and Wang used more photos of males than females, with no picture of a female doctor in a suit. A white coat being voted highest for the female doctor could just be because this was the most formal style. Issues and debates Application to everyday life The research moves the responsibility for communication barriers from the patient to the practitioner. Strategies can be used to change working practices in health care and improve comprehension. Idiographic versus nomothetic The research uses a nomothetic approach, focusing on groups of people. This is useful for generalisation of findings, but an idiographic approach using qualitative methods would discover individual needs. For example, patients with minor problems would require different styles of communication from those with mental health problems or serious illness.

[4] 8.3Outline what is meant by utilisers and underutilisers when referring to attendance at health facilities. [2] 8.4 Explain one strength and one weakness of research into practitioner and patient interpersonal skills. [4] 8.1.2 Patient and practitioner diagnosis and style Practitioner diagnosis Disclosure of information Misunderstandings when communicating symptoms can occur because of: » patients’ – lack of vocabulary – unwillingness to give information – mistrust of the doctor » the practitioner’s gender: Hall et al. (1994) found that patients gave more information to female practitioners, who asked more questions and conducted longer appointments. Practitioners should correctly diagnose ill people as ill, and healthy people as healthy: » A false positive is when a healthy person is diagnosed as ill when they are not. » A false negative is when an ill person is diagnosed as healthy. This is medical negligence and the consequences can be serious. Presenting a diagnosis Non-verbal communication is more important than verbal communication when presenting a diagnosis: » Shapiro et al. (1992) found that female participants receiving mammogram results from a ‘worried’ practitioner remembered fewer details than those receiving results from a ‘not worried’ practitioner. » During the COVID-19 pandemic, telephone diagnoses meant there was no nonverbal communication, increasing the risk of misunderstandings. Key study: Savage and Armstrong (1990) Context: » Research has shown that a sharing style is preferred by patients and this ensures they follow medical advice willingly. » A traditional directed style is seen as paternalistic and limiting patient autonomy. SKILLS BUILDER Valerie is giving a diagnosis of serious illness to a patient. Explain one way that Valerie could ensure that the patient remembers as much as possible of the information she is relating. [4] Combine your knowledge of practitioner verbal and non-verbal communication with what you have learned about diagnosis and style. How might Valerie’s style and communication affect the way her patient remembers the consultation and diagnosis? The question only requires you to write about ‘one way’. Choose your best idea and explore it in detail. Aim: to investigate whether a sharing consultation style increases patient satisfaction compared to a directed style. Research method(s) and design: field experiment. Variables: » Independent variable: directed or sharing consultation style. » Dependent variable: patient level of satisfaction. » Controlled variables: random selection of patients; same doctor used throughout. 184 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 184 14/08/23 7:19 PM 8 Health Psychology Sample: 200 randomly sampled patients (aged 16–75) from a London GP practice. Procedure: » Participants were randomly allocated to the ‘directed’ or ‘sharing’ practitioner style by cards placed on the doctor’s desk, face down. » The doctor also had prompts giving examples of directed and sharing styles of consultation. » At the end of the consultation, the participant completed a five-question questionnaire (see Table 8.5). » Participants received a second identical questionnaire to mail back one week later. » Researchers noted the length of consultation and demographics. Ethics: participants gave consent for their appointments to be audio-recorded. Results: ▼ Table 8.5 Results of questionnaires Questionnaire 1 (%) Questionnaire 2 (%) Directed Sharing Directed Sharing I was able to discuss my problem well. 73 74 61 53 I received an excellent explanation. 45* 24* 33* 17* I perceived the practitioner to have complete understanding. 62* 37* 39* 18* I felt greatly helped. 54 45 49* 28* I felt much better 33 32 33 26 *significant difference Conclusion: » Patients with simple physical illnesses benefit more from a directed style of consultation. » Patients prefer certainty and paternalism – doctor to be the authority figure. » Directed style did not provide greater satisfaction during longer advisory consultations when patients had chronic or psychological illnesses. ▼ Table 8.6 Methodological issues Strengths Weaknesses Ecological validity – Savage and Armstrong’s (1990) study was a real-life setting, with a real doctor and their patients. Ecological validity – Shapiro et al.’s (1992) participants watched video clips of practitioners giving a diagnosis and evaluated them. Savage and Armstrong’s doctor followed prompts, which may not match their normal style, and thus may have affected patients’ experiences. This lowers the validity of both studies. Holistic approach – Shapiro et al.’s research focused on the practitioner’s and patients’ verbal and non-verbal communication. This holistic approach increases validity. Cultural differences – Elwyn et al. (2002) reported how in the USA patients are told the diagnosis, no matter how serious it is; but in Japan patients are often not told about a serious or terminal diagnosis (Noguchi, 2007). Cultural factors are important when presenting diagnoses. Representativeness – participants selected by random sampling are representative of patients registered to the doctor. Opportunity sampling might have meant only those known well were selected. Generalisability – in Savage and Armstrong, 11 per cent of patients did not complete the first questionnaire and 44 per cent did not complete the second. This lowers generalisability. Issues and debates Application to everyday life There are significant applications to everyday life. By understanding which style of consultation works best, practitioners can adapt to suit individual patients. This may help with information disclosure, meaning more accurate diagnoses.

(1979) » People have different thinking and decision-making processes when first experiencing a symptom from when first suspecting illness. » They lack trust in doctors. » They perceive stigma around seeking treatment for mental health concerns. Fernando et al. (2017) » People in Sri Lanka are influenced by their own and family’s perception of stigma. » 15 per cent of patients and carers reported delays in seeking help due to stigma-related concerns.

(2007) » The median duration of delay was one year for mood disorders, but 16 years for anxiety in a Belgian sample. » The onset of mental disorders might be during childhood/adolescence and so viewed by people as normal. Health belief model According to the health belief model (HBM), people who feel threatened by their symptoms tend to see a practitioner more quickly, whereas those who view symptoms as no threat, delay or avoid seeking medical help. ▼ Table 8.8 HBM explanation for delays in seeking medical help 186 Perceived… Explanation Threat Extent to which someone views a health problem as being serious affects cues to action Susceptibility Extent to which someone thinks they are at risk of a certain illness Seriousness How serious the patient thinks their health problem is Benefits What the patient views as the advantages of treatment Barriers Anything the patient thinks will make it difficult to follow a treatment programme STUDY TIP Using your knowledge of the practitioner– patient relationship and of misusing the health service, make yourself a mind map of all the reasons why a person might delay seeking treatment.

(1979) Context: most research into delays in seeking medical care focuses on the time between noticing the symptom and the first appointment. Safer et al. investigated whether delay can be broken into different stages and factors, involving different decisions/processes. Aim: to investigate factors that influence delays in seeking medical treatment. Methodology: » A 45-minute structured interview with an opportunity sample of 93 patients in a waiting room of an inner-city hospital. » If the patient was seeing a practitioner about a new symptom or illness, they were asked to take part in the study. » They were asked questions about symptoms and reactions, such as ‘Do you expect the treatment will be uncomfortable?’ » Patients were given: – a scale to measure emotional reactions to symptoms. – a seven-item scale measuring the extent to which they imagined negative consequences of symptoms and treatment. – a ten-item scale measuring level of pain. » Patients were asked length of delay at illness stages (see Table 8.9). ▼ Table 8.9 Safer et al.’s four stages of delay Delay stage Description Appraisal Delay from first noticing symptoms to concluding they were ill Total Delay from first noticing symptoms to first appointment Illness Delay from deciding they were ill to deciding to get medical help Utilisation Delay from deciding to seek help to attending appointment Results: ▼ Table 8.10 Length of delay at each stage Delay stage Length of delay in days Appraisal » Pain: severe = 2.5; none = 7.5 » Reading about symptoms = 19.6; not reading = 3.5 » Bleeding = 1.2; no bleeding = 4.8 Total » Competing problem/issue = 23.8; no competing problem = 7.2 » Severe pain = 8.6; little/no pain = 23.8 » Reading about symptoms = 50.2; not reading = 11.5 Illness » New symptoms = 2.5; old/frequently experienced = 11.3 » Negative visual imagery of outcome = 4.4; no negative imagery = 1.9 Utilisation » Concerned with cost = 9.7; not concerned = 2.0 » Severe pain = 1.6; little/no pain = 3.8 » Felt symptoms incurable = 4.3; felt curable = 1.8 Conclusions: » Bleeding or severe pain reduces the delay in seeking medical help. » Negative imagery, concerns over costs, researching symptoms and believing symptoms are incurable all increase delay. Munchausen syndrome Munchausen syndrome (factitious disorder) is when people seek out excessive medical attention, often going from city to city to get a new diagnosis and new surgical intervention. It is not malingering, which is when a person feigns or exaggerates symptoms for an obvious gain or incentive. There is no thought of gain with Munchausen syndrome. It is thought to be very rare, but prevalence is hard to establish due to the deception involved. SKILLS BUILDER Explain one feature of a structured interview as a way of investigating factors influencing delays in medical treatment. [2] First, bulletpoint some ideas about structured interviews. Refresh your memory by revisiting section 5.1.5 if you need to. Which of these features would make structured interviews especially useful for investigating factors influencing delays in medical treatment? Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 187 187 14/08/23 7:19 PM Aleem and Ajarim (1995) developed a list of diagnostic features of Munchausen syndrome (see Table 8.11). ▼ Table 8.11 Diagnostic features of Munchausen syndrome (Aleem and Ajarim, 1995) Essential features Supporting features Pathological lying (pseudologia fantastica) Borderline and/or antisocial personality traits Peregrination (travelling or wandering) Deprivation in childhood Recurrent feigned or simulated illness Equanimity for diagnostic procedures Equanimity for treatments or operations Evidence of self-induced physical signs Knowledge of or experience in a medical field Most likely to be male Multiple hospitalisations Multiple scars (usually abdominal) Police record Unusual or dramatic presentation Relevant research: Aleem and Ajarim (1995) Aim: to present a case study of Munchausen syndrome. Methodology: » A 22-year-old female university student was referred to hospital with a possible case of immune deficiency or neutrophil disorder. » She was initially investigated at the age of 17 for menstrual cycle issues. » She developed symptoms of deep vein thrombosis; medication to treat this was ineffective. » She was admitted to hospital aged 22 with a painful swelling on her breast. » She told doctors of similar swellings previously over her abdominal wall which had required drainage at other hospitals multiple times – there were scars. » Later she had abscesses drained and doctors discovered suspicious bacteria in fluid. Findings: » The psychiatrist diagnosed Munchausen syndrome. » A nurse found a syringe containing faecal matter with which the patient had been injecting herself. » The patient became angry when informed and left hospital. Conclusion: Munchausen syndrome diagnosed, but nothing further could be concluded. ▼ Table 8.12 Methodological issues 188 Strengths Weaknesses Case study – Aleem and Ajarim (1995) used an appropriate method for a condition that is difficult to research ethically; experimental method cannot be used. Validity – Safer et al. (1979) used retrospective data. Memories could be inconsistent, especially under stress. Usefulness – from Safer et al., medical practices can develop strategies to reduce patient delays. Aleem and Ajarim provides information, allowing more reliable diagnosis of Munchausen syndrome. Reliability – qualitative data is subject to interpretation by the researchers. For example, Aleem and Ajarim possibly interpreted information about the first hospitalisation differently due to already knowing about the discovered syringe.

This makes it hard to isolate which variables have the strongest effect in delaying seeking treatment. It is also difficult to create effective interventions. A more reductionist approach may be necessary, but it is often impossible to manipulate variables for practical and ethical reasons. Idiographic versus nomothetic An idiographic approach with rich in-depth information is appropriate in Aleem and Ajarim (1995) as Munchausen syndrome is relatively rare and generalising from small samples in a nomothetic manner may not be valid. Practitioners can decide whether findings may apply to their own clients. SKILLS BUILDER Julia wants to conduct a case study about a client she is working with who has Munchausen syndrome. Explain how Julia might collect and analyse her data. [4] This will involve knowledge of method triangulation. What advice would you give Julia to ensure that her findings are valid and reliable? If you need to, revisit the sections on case studies, validity and reliability in Chapter 5. NOW TEST YOURSELF 8.9 Donald decides he needs some time off work and is going to ‘be ill’ for a few days.

[4] 8.2 Adherence to medical advice 8.2.1 Types of non-adherence and reasons why patients do not adhere Adherence to medical advice is when patients follow specific guidance from health professionals. Failure to follow treatments » Unintentional non-adherence: the patient wants to follow a treatment but there are uncontrollable barriers: – not remembering – not understanding the doctor – unable to afford treatment – unable to take time off work – simply forgot. » Intentional non-adherence: the patient decides not to follow treatment. This may be due to their beliefs, levels of motivation or lack of faith in the treatment. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 189 189 14/08/23 7:19 PM Laba et al. (2012) identified six intentional factors: 1 2 3 4 5 6 Immediate medication harms Long-term medication harms Immediate medication benefits Long-term medication benefits Financial cost of medication Regime (See ‘Relevant research’ below.) Failure to attend appointments Individual failure to attend appointments is an expensive and persistent worldwide problem. Previous failure to attend appointments predicts future failure to attend. Other predictors are: » age (either young or over 80 years old) » work commitments » difficulties getting to hospital » feeling an appointment is unnecessary » being too ill to attend » fear/mistrust of hospitals » fear of serious illness being discovered. Parsons et al. (2021) reviewed 12 studies, reporting that work/family commitments, forgetting an appointment and transportation difficulties were most commonly reported reasons. Most likely to miss appointments are: » those under 21 » those from low social status/class » individuals who have missed appointments previously » those who already have a mental or physical diagnosis » minority ethnic groups. STUDY TIP Draw a Venn diagram for unintentional and intentional nonadherence to medical treatment. You should have found that financial issues were in the overlapping section of the diagram. This is one of the factors identified by Laba et al. (2012). Look at the list of reasons why people do not attend medical appointments and see how many could be down to financial problems. This shows you the web of connections between non-attendance at appointments and nonadherence to advice and medication. Draw yourself a diagram of the links. Learning these and thinking about how they apply in real life helps with a depth of understanding that memorisation cannot give. Problems caused by non-adherence include: » unresolved medical problems » cost to health service » delayed treatment, leading to: – later need for more expensive, stronger medication – later need for surgery. Explanation of non-adherence Rational non-adherence Reasons (Sarafino, 2006): » Believing medication is not helping. » Feeling that the side effects outweigh the benefits. » Being confused about how often/how to take medication. » Not having enough money to buy medication. » Wanting to see if they still have the illness if they stop taking medication. Bulpitt and Fletcher (1988) researched non-adherence to medication with side effects in patients with high blood pressure: » Eight per cent stopped due to sexual problems. » Fifteen per cent stopped due to tiredness, sexual problems and gout. » Patients stopped when the side effects outweighed the benefits. Health belief model Taking preventative action when faced with potential illness or injury depends on: » how much of a threat the health problem poses » the pros and cons of taking action. 190 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 190 14/08/23 7:19 PM 8 Health Psychology ▼ Table 8.13 Health belief model explanations for action Consideration Preventative action more likely if: Perceived seriousness Problem considered serious Perceived susceptibility Patient feels susceptible to problem Cues to action Cues seen – appointment reminders, advertisements, posters Perceived benefits/barriers More perceived benefits than barriers Other factors include demographic variables, personality traits and social class. Relevant research: Laba et al. (2012) Aim: to explore decisions that may lead to intentional non-adherence behaviour and the relative importance of medication-specific factors and patient background. Methodology: experiment: » 248 Australians; median age: 57 years; 45 per cent male, 55 per cent female. » 161 participants completed an online survey. » The Beliefs About Medication Questionnaire (BMQ) was used to create a tenquestion discrete-choice questionnaire on two hypothetical drugs. ▼ Table 8.14 Example of a discrete-choice question Symptom severity On medication, daily symptoms are now felt The severity of daily medication side effects For every 100 people taking this medication, the number of people who will have unwanted effects in the next ten years is: For every 100 people with this illness, 85 will die in the next ten years. On medication, this number reduces to: The medication is taken: Can you drink alcohol? Your monthly cost for the medication Which would you prefer? Medication A 1 out of 10 6 days per week 1 out of 10 35 Medication B 7 out of 10 2 days per week 4 out of 10 95 65 65 Once a day Yes $10 Once a day Yes $50 » Six out of eight factors influenced medication choice. » Those with medical insurance were less sensitive to costs. » Side effects had greater influence than benefits to health. » The ability of medication to reduce death was most important, followed by current side effect severity and future side effect risk. Conclusions: » Patients make rational choices. » Adherence could be improved by: – reducing costs of medication – altering regime – educating patients on medication benefits. ▼ Table 8.15 Methodological issues Strengths Weaknesses Usefulness – results from Laba et al. (2012) show factors that influence patients’ adherence to their treatment regime. This could help practitioners design interventions to improve adherence. Representativeness – 1,668 people were initially invited to participate. However, only 248 respondents commenced the questionnaire and 161 completed it = 10 per cent participation rate. Maybe a certain type of person participated. Reliability – objective quantitative data from discrete-choice Ecological validity – the questionnaire scenarios questionnaire meant that the results had high reliability. were all hypothetical and may not reflect real life. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 191 191 14/08/23 7:19 PM Issues and debates Application to everyday life Explanations of non-adherence are applicable to real life. If health service professionals understand that cost and complexity affect non-adherence then strategies to overcome this can be introduced, such as lowering the cost or making instructions clearer. Idiographic versus nomothetic Laba et al.’s nomothetic approach allowed generalisable conclusions about rational non-adherence. Quantitative data collected using fixed-choice questions and statistically analysed led to objective and reliable findings. A lack of open questions meant participants could not explain. Adding an idiographic approach may have helped to gain greater insight.

Methodology: » Fifty-two of the original 94 families (parents plus adolescents aged 11–18) completed the study. » Adolescents had diabetes for over a year. » Participants were recruited through a clinic. » They were interviewed using the Adherence and IDDM Questionnaire-R, regarding: – diet – glucose testing – preparedness for hypoglycaemia. » Number of blood glucose tests was monitored through a reflectance meter. » Metabolic control was measured at clinic appointments. » Parents completed a questionnaire on demographics and the family took two questionnaires, to be mailed back. » Researchers reviewed medical charts of all 94 adolescents initially requested to take part, to obtain the number of blood glucose tests per day and metabolic control levels. Demographic data of families refusing to take part was also obtained. Results: » Demographics were similar for all three groups: participants completing the study, those not returning the questionnaires (non-returners) and those not consenting to take part (non-consenters). » Adolescents of non-returner families tested their blood glucose levels significantly less frequently than those of families who returned the questionnaire, or non-consenter families. » Adolescents of non-returner families also had significantly lower rates of adherence than those of families who returned their questionnaires. Conclusion: lower adolescent adherence to treatment regime is associated with lower participation in adherence studies by adolescents and their families. Objective measures ▼ Table 8.17 Objective measures of adherence Method Details Strengths Weaknesses Pill counting Typically conducted in person at clinic. » Unannounced pill counts Medication dispensers Dispensing correct pills at set day/time; can use visual/audio alarms; also record date and time pill leaves device, and frequency of use. » Advantage to patient as » Lacks validity: just because they are more likely to take medicine with reminders, meaning relapse less likely. » It is a reliable way to measure adherence. medicine was removed from dispenser does not mean it has been taken. » Helps forgetfulness, but not deliberate non-adherence. » Burden to patients as they by telephone or home have to attend clinic with visits overcome patient medication. manipulation. » Patients may manipulate pill » Increases validity: there was count if they know date and a 92 per cent agreement time of check, decreasing between telephone and home validity. pill counts and measures of viral load in HIV+ patients (Kalichman et al., 2008).

Methodology: » Forty-seven patients with asthma, aged 18–55. » Two to three weeks of screening, then 12 weeks’ treatment; one pill twice a day. » Tablets in bottles fitted with TrackCap recording date and time when opened. » Patients gave informed consent but did not know about the device. » Tablet count and TrackCap removal were both measured. Results: » There was 80 per cent compliance with TrackCap (taken off twice a day); 89 percent compliance with tablet count. – Difference due to patients taking out more than one tablet at a time, maybe to put in a dispenser. » There was 64 per cent compliance on TrackCap and tablet count: two tablets daily, 12 hours apart. » Under-compliance by 20 per cent of participants: one tablet removed daily. » No compliance for up to eight days by 10 per cent of participants. Conclusion: monitoring systems like TrackCap measure adherence effectively. Biological measures of adherence » These provide assurance that medication has been taken, not just removed from the bottle. » They allow for a personally adjusted dose to be calculated. ▼ Table 8.18 Biological measures of adherence Method Details Strengths Weaknesses Urine analysis Donated in sterile jar » Chemically stable for 14 days Drug/drug and drug/food interactions may interfere with accuracy of results.

Traditional sampling is invasive and some find it unpleasant/ stressful, so it is not suitable for all patients. ▼ Table 8.19 Methodological issues 194 Strengths Weaknesses Application to everyday life – in Riekert and Drotar (1999), the families not completing research tasks may lack organisational skills. This allows reallife interventions for non-participants, increasing adherence. Chung and Naya (2000) measured adherence at home when patients would normally take medication. Ethical issues – Reikert and Drotar used data from non-consenters. There are ethical issues about informed consent and using information without permission. Chung and Naya deceived participants as to how they were monitored. Quantitative data – electronic monitoring is objective, giving quantitative analysis of adherence to medical advice. No social desirability bias or misremembering means increased validity. Validity – Chung and Naya found adherence rates to be high. However, participants knew adherence was being measured. It would have been more valid if participants were blind to the true aim.

Asthma can cause breathing difficulties in all ages. Spacer devices are plastic containers with a mouthpiece or mask at one end and a space to insert an asthma inhaler at the other end. Fitting over the mouth, they can be scary for children. The Funhaler is based upon operant conditioning principles, where children are rewarded if they use the device correctly, making them more likely to repeat it. The rewards are spinners and a whistle activating if the device is used correctly.

Key study: Yokley and Glenwick (1984) Context: » The researchers wanted to investigate behavioural psychology applied to increasing immunisation adherence. » At the time of the research, preventable diseases such as polio, whooping cough, tetanus and rubella killed over five million children worldwide. » Yokley and Glenwick (1984) reported 10,000 cases of preventable diseases in the USA. Aim: to evaluate the impact of four conditions on motivating parents to have children immunised. Research method(s) and design: field experiment; longitudinal design. Variables: » Independent variables: 1 General prompt to parents regarding immunising their children. 2 Specific prompt with dates, times and locations. 3 Specific prompt with extended clinic hours, drinks, movies and snacks. 4 Specific prompt with monetary incentive (three prizes of $100, $50 and $25). » Dependent variables: 1 Number of children receiving one or more immunisations at the clinic. 2 Number of children attending clinic (for any reason). 3 Total number of immunisations received by children. » Controlled variables: 1 Contact control group: received telephone call asking whether child was immunised and general demographic information, but no specific prompt to have child immunised. 2 No contact control group: received no contact during the study. 3 Parents with two or more immune-deficient pre-schoolers were assigned to conditions as families, to prevent siblings being in different conditions of the IV. Sample: » Participants were 715 pre-school immune-deficient children; 50 per cent female; 64 per cent white. » The children needed one or more inoculation for diphtheria, tetanus, whooping cough, polio, measles, mumps or rubella.

Generalisability – in Chaney et al. (2004), 32 Australian children is not representative of the wider population. This only showed differences with children already used to a conventional spacer. Yokley and Glenwick’s (1984) findings may not generalise to other parts of the USA or other countries. The final sample was 36.9 per cent less than the original, so the results may also not be representative of the target population. Reliability – Yokley and Glenwick used standardised procedures, meaning research is replicable. Validity – in Chaney et al., parents probably wanted to show they were doing their best for their children, so put in extra effort to ensure adherence; this lowers the validity of results. Issues and debates Use of children in research Although Yokley and Glenwick (1984) used children in their research, the focus was on parental behaviour. It is still important to consider the effects on children’s immunisation. Control groups received a follow-up reminder letter after the study ended, ensuring no group was disadvantaged. Chaney et al.’s (2004) research took place in children’s own homes, with full parental permission and minimal researcher contact. All ethical considerations were met. Applications to the real world Yokley and Glenwick’s study has practical applications. Where immunisation levels are low and preventable diseases are returning, incentivised programmes might increase the number of immunisations. SKILLS BUILDER Suggest one ethical issue Yokley and Glenwick (1984) would have considered when conducting their research into immunisation adherence. [2] Your first sentence should identify a suitable ethical issue. Bullet-point your ideas first; a mnemonic like DRIP will remind you to think about deception, right to withdraw, informed consent and protection from harm (including confidentiality and privacy).

Those believing pain is a threat to health will rate the affective level as higher than someone who believes the same pain is just because they over-exercised. Individual response to pain is affected by social, genetic and cognitive factors. Pain’s function is to prevent us from further injuring ourselves. Doctors use pain as a clue when diagnosing. Acute and chronic pain Acute pain is sudden, sharp pain lasting less than six months (ICD-11). Chronic pain: » usually lasts longer than six months » causes high levels of anxiety and exhaustion » can affect sleep and impact the ability to lead a normal life. STUDY TIP A good working knowledge of the syllabus will mean you should not be short of ideas on some of the less predictable questions (e.g. Paper 4, Section B). Look at your revision checklists regularly and practise sorting topics into their respective categories until you can remember all the specific research methods and studies that you need to know for each section. Phantom limb pain » Phantom limb pain is experienced by 80 per cent of people after limb loss. » It is more common in women than men. » It may be explained by mixed signals, brain adjustment or damaged nerve endings. » It is a chronic condition, either recurrent or intractable, described as ‘shooting’, ‘burning’ or ‘cramping’ pain (Sarafino, 2006). Mirror treatment » Mirror treatment uses a mirror to create the illusion of the amputated limb being there, by placing the opposing limb in front of the mirror, with the amputated limb behind it. » The patient massages and moves the opposing limb and feels the benefit in the phantom limb. » Ramachandran et al. (1995) describe how this breaks the negative feedback loop telling the brain the limb is not moving and establishes new connections to ‘feel’ it again, easing the pain. Relevant research: MacLachlan et al. (2004) Aim: to report the effects of mirror treatment on a person with lower limb amputation. Methodology: » Case study of 32-year-old man with leg amputation. » He had used painkillers and a Transcutaneous Nerve Electrical Stimulation (TENS) machine for phantom limb pain, but it worsened. » He then tried mirror treatment. Results: » Pain reduced to 0 on a 0–10 scale. » He felt more control over the phantom limb than prior to mirror treatment. Conclusion: » Mirror treatment is effective for phantom limb pain. » It avoids patients taking pain medication, giving them control over their pain. 200 ▲ Figure 8.2 Mirror treatment for phantom limb pain SKILLS BUILDER Suggest two reasons why a psychologist might choose a case study to investigate pain treatment. [4] Make a list of the advantages of case studies, thinking, for example, about the idiographic approach, triangulation of methods or type of data.

The more the specific pain pathway (pain nerve fibres and specific pain centre) is used, the more intense the pain is. Gate control theory Melzack and Wall (1965) proposed this theory of pain based on the action of T-cells (transmission cells): » Small, slow fibres carry pain stimulation to the spinal cord. » They pass through a ‘gating mechanism’, activating T-cells to transmit the pain signal to the brain. » The extent to which the gate is open depends on the following: – Activity level in slow pain fibres: the more activity there is, the wider the gate opens. – Activity level in other peripheral fibres: they carry information about harmless stimuli or mild irritations and close the gate. – Messages from the brain to the spinal cord: neurons in the brainstem and cortex send impulses relating to emotions down the spinal cord to open or close the gate: – Anxiety and boredom open the gate. – Happiness and distraction close it. SKILLS BUILDER Evaluate one theory of pain, including a discussion of nature versus nurture. [10] This question allows you to evaluate just one theory of pain from this section, focusing in detail on the supporting evidence and the issues and debates. Remember to discuss nature versus nurture. ▼ Table 8.24 Methodological issues Strengths Weaknesses Application to everyday life – MacLachlan et al.’s (2004) case study of mirror treatment shows how it could be used by practitioners or even by people in their own homes. Validity – specificity theory is now outdated and discredited. There is no physical evidence of a gating mechanism in the spinal cord, suggesting other mechanisms might be involved. MacLachlan et al.’s study results could have been a ‘placebo effect’ – just receiving treatment can have positive effects. Attention from clinicians as part of the treatment may have contributed to the results. Case study – MacLachlan et al.’s research gave detailed insight into the patient’s background and effectiveness of treatment compared to other treatments. Generalisability – MacLachlan et al.’s findings cannot be generalised to the wider population as individual experience with mirror treatment differs. Pain is subjective and varies with culture and gender. Issues and debates Nature versus nurture The gate control theory of pain focuses on the nature side of the debate. However, this ignores environmental (nurture) factors affecting pain perception, such as hearing other patients in pain or harsh overhead lighting. It also ignores other factors that can reduce pain, such as psychological treatments. Reductionism versus holism Gate control theory and MacLachlan et al.’s research take a holistic approach to pain, accounting for both physical and psychological factors. However, neither accounts for individual differences in pain experience. NOW TEST YOURSELF 8.25 Explain one strength and one weakness of qualitative data, using research from pain treatment as an example. 8.26Outline one feature of mirror treatment for phantom limb pain. 8.27 Explain one weakness of the gate control theory of pain. 8.28 Describe the placebo effect in relation to treatment for pain.

Clinical interview » Clinical interviews are used to assess patients with chronic pain. » They allow observation and assessment of a patient’s emotional state and beliefs about pain causes. » They may use psychometric tests to help understand the type and intensity of the patient’s pain, everyday functioning, emotional distress, beliefs and expectations. Evaluation » Strength: they are an effective way to assess pain. Although using standardised questions, the physician can ask patients to elaborate to allow for a tailored treatment plan. This increases adherence and likelihood of treatment success. » Weakness: they may not be effective for all as they rely on good communication and trust between patient and physician. Psychometric measures and visual rating scales McGill pain questionnaire The McGill pain questionnaire (MPG) was constructed by Melzack and Torgerson (1971), who asked doctors and university graduates to group 102 adjectives describing different aspects of pain. They identified four categories, subdivided into 20 questions: 1 Sensory (questions 1–10): patients choose word describing their pain. 2 Affective (questions 11–15): looking at emotions the pain makes the patient feel, with choices from numbered words such as tiring, sickening or fearful. 3 Evaluative (question 16): subjective intensity of pain, measured on a five-point scale. 4 Miscellaneous (questions 17–20): various aspects of pain on three-to-five point rating scales. Three major results measurements: » Pain rating index (PRI): high score = high pain levels. Total score given for all questions, plus sensory, affective and evaluative score. » Number of words chosen. » Present pain intensity (PPI) at time of the questionnaire. Evaluation Strengths: » Reliable: Ferraz (1990) found r = +0.96 correlation between 91 patients in a testretest analysis. » Valid: Byrne et al.(1982) compared results of patients with back pain to previous research and found similar results. Weaknesses: » Quantitative pain measures may limit the patient’s ability to communicate their real experience of pain: descriptive words used in questionnaire do not fit their experience; or may misunderstand the terms used. Visual analogue scales Visual analogue scales (VAS) avoid some problems with language by also using pictures. The psychometric scale is designed to measure subjective pain along a continuum. The patient identifies their current intensity of pain. It can be completed on each clinic visit to monitor pain. 202 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 202 14/08/23 7:20 PM 8 Health Psychology No pain 0 Mild, annoying pain 1 Nagging, uncomfortable, troublesome pain 2 3 4 Distressing, miserable pain 5 Intense, dreadful, horrible pain 6 7 8 Worst possible, unbearable, excruciating pain 9 10 ▲ Figure 8.3 An example of a VAS for measuring pain Evaluation Strengths: » It is quick and easy to use. » It is designed to show pain on a continuum, so no ‘gaps’ in pain intensity. » Patients should feel their pain is represented on the scale, so it is a valid measure. Weaknesses: » Patients are unable to elaborate on pain experience and its impact. » It is a basic measurement of pain. Behavioural measures UAB pain behaviour scale » The UAB pain behaviour scale measures observable pain behaviour and verbal/ non-verbal signs of pain. » Using a three-point scale, an observer judges how frequently each behaviour occurs across a three-week period. ▼ Table 8.25 One measure on the UAB pain behaviour scale Body language (clutching, rubbing of site of pain) M T W T F S S M T W T F S S M T W T F S S None 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Occasional ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ ½ Frequent 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Evaluation Strengths: » It is quick to score and easy to use. » It can be used with a large number of patients, including those who cannot complete a self-report. » A wider sample makes results more generalisable. Weaknesses: » It is dependent on the observer’s ability to accurately record pain behaviour. » There is a low correlation between observer scores on the UAB and self-reports on the MPQ. Key study: Brudvik et al. (2016) Context: » Research shows that hospital doctors underestimate children’s pain, administering pain relief medication less often, later and at lower doses than for adults. » Parents are better estimators than nurses, yet they still underestimate their children’s self-reported pain (Rajasagaram et al., 2009). Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 203 203 14/08/23 7:20 PM Aims: to explore » the relationship between children’s self-reported pain and parents’ and doctors’ pain ratings » how age, medical condition and severity of pain affect pain estimates » whether pain assessment affects administration of pain relief. Research method(s) and design: field study; correlational, using questionnaires. Variables: » Dependent variables: – Numeric rating of child’s pain by doctors and parents. – Three- to eight-year-olds’ responses on two visual analogue scales (e.g. see Figure 8.4). – Nine- to fifteen-year-olds’ responses using a visual analogue scale, with a coloured green–red line. Sample: opportunity sample of 243 paediatric patients aged 3–15 years old (mean age: 10.6), their parents and 51 doctors. Procedure: » Participants completed scales and questionnaires as detailed in ‘Variables’ above. » Parents answered demographic questions. » Doctors gave details of experience, whether they were parents, pain relief given and match between child’s rating and their own. » Child’s diagnosis classified as infection, fracture, wound injury or soft tissue, ligament or muscle injury. » Each family’s total waiting time was recorded. Ethics: » Parents gave written consent for themselves and their children. » The researchers ensured someone was always available to provide extra support or guidance. » The children’s medical condition could change rapidly, so it was important parents knew someone was available if they wished to exercise their right to withdraw. Results: » Only 42 per cent of children with severe pain (judged by doctors) were given pain relief medication. » Only 14.3 per cent of children self-rating pain as severe were given pain relief medication. Conclusion: » Doctors significantly underestimate pain in 3–15-year-olds. » Anxiety increases pain perception. » Doctors should place higher value on parental reports of children’s pain. ▼ Table 8.26 Methodological issues 204 Strengths Weaknesses Reliability – the MPQ was standardised. Brudvik et al. (2016) used a standardised procedure. Generalisability – Brudvik et al. only looked at one Norwegian emergency department. They were not specialist children’s doctors, so they did not routinely assess pain. Doctors in other countries may have assessed children’s pain more accurately. Validity – Byrne et al. (1982) tested MPQ comparing results of patients with back pain to previous research and found similar results. Brudvik et al. was in a natural setting, where doctors had usual routines, with limited time to conduct consultations. Validity – in Brudvik et al., parents and children knew each other’s answers. The children’s answers may have been influenced by their parents’ reactions.

Open questions would have collected qualitative data; a more idiographic approach means they could have learned more about how/why some children experience greater pain than others. Application to everyday life The study can be used to support changes in Norwegian paediatric care. Training should include listening to children/parents regarding pain levels and remembering individuals with the same condition may experience pain differently. This is critical due to links between pain, recovery time and long-term problems like hypersensitivity. NOW TEST YOURSELF 8.29 Explain one strength and one weakness of Brudvik et al.’s (2016) research into children’s pain. [4] 8.30Outline what is meant by the nomothetic approach, using an example from research into measuring pain. [2] 8.31 Explain why an understanding of cultural differences is important in research into measuring pain. [4] 8.32Tomas is conducting research into measuring pain. He plans to design and then test a questionnaire on chronic pain level in people over 65, by asking them to complete it and then comparing their answers with a standardised self-report measure. a Suggest one strength and one limitation of the questionnaire method for measuring pain. [2] b Suggest an additional method he could use to gain more data. [2] SKILLS BUILDER From the key study by Brudvik et al. (2016) on children’s pain, explain one strength of the data gathered using visual analogue scales. [2] Think about the strengths of visual analogue scales and choose the one that applies most to children needing to rate their pain. Explain the strength in terms of how it is particularly related to children. 8.3.3 Managing and controlling pain ▼ Table 8.27 Biochemical pain treatments Type Example Description Strengths Weaknesses Analgesics (painkillers) Paracetamol Very common type of painkiller Safe: serious side effects rare (Prescott, 2000) » No better than placebo for Effective for reducing fever, inflammation and headache pain » Side effect – stomach Effective in treating acute pain (Rosenblum et al., 2008) » High doses slow breathing NSAIDs (e.g. ibuprofen) Opiates Non-steroidal anti-inflammatory drugs to reduce pain, inflammation and temperature Strong painkillers like morphine and codeine chronic pain » Only effective in small numbers of people for acute pain (Moore, 2016) » Exceeding dose is extremely dangerous irritation » Conflicting research on safety: decreased risk of Alzheimer’s disease but increased risk of breast cancer and heart rate » Addictive Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 205 205 14/08/23 7:20 PM Type Example Description Strengths Weaknesses Local Novocaine anaesthetics Injected near to the body area affected and stops nerves sending pain signals to brain Fast-acting. Acts within 5–10 minutes » Can wear off after 30 Indirect medication The painkilling mechanism of antidepressants is not totally understood; they may increase the neurotransmitters in the spinal cord to reduce pain signals Useful for chronic pain like migraines, back pain and sciatica Do not work immediately and pain relief is not total Antidepressants minutes, so often has to be combined with another painkiller ▼ Table 8.28 Psychological treatments Type Example Description Cognitive strategies Attention diversion Using distraction to help reduce » Inexpensive, selfpain perception administered, effective, no side effects » Significantly reduces perceived pain and increases quality of life (Holden, 2013) Non-pain (guided) imagery Helps reduce moderate pain by imagining a pleasant scene unrelated to the pain experience; therapists ‘guide’ the patient to imagine the scene » No side effects » Patients have control Cognitive redefinition Through having clear information, patients are helped to think fearlessly and rationally about pain, challenging irrational thoughts » No side effects » Ineffective when » Positive self-statements fears are rational Alternative treatments Strengths over pain management » Can be used whenever/ wherever needed are helpful Weaknesses » Requires full belief in the power of distraction » Less useful for long periods as difficult to maintain visualisation » Not everyone can visualise things and based on past experience Acupuncture Fine metal needles inserted » Reduce medication dose » Some people fear under skin and swivelled around and side effects needles or mild electrical current passed » Research support with » For severe pain, through to relieve pain; might cancer patients this needs to be be explained by gate control (Hu et al., 2016) used alongside theory of pain conventional drug therapy Stimulation/ TENS Electrodes placed on skin near site of pain; mild electrical current passed through the skin; may also be explained by gate control theory Effective during labour (Kaplan et al., 1998) Effects are short-lived with chronic conditions like phantom limb pain (Sarafino, 2006) ▼ Table 8.29 Methodological issues 206 Strengths Weaknesses Usefulness – psychological treatments have no side effects. Patients feel in control of their own pain management. Biological treatments are usually effective against severe pain. Effectiveness – psychological treatments alone are ineffective for severe pain. Biological treatments may have harmful side effects or be addictive. Adherence – people are more likely to adhere to psychological treatments if pain is moderate and/or short-lived, as side effects are one of the main reasons for non-adherence. Reductionist – biological treatments are reductionist, focusing on the biological mechanisms of pain and ignoring environmental factors.

Paracetamol is often prescribed for pain despite research finding it ineffective for many, and individuals also experience differences in side effects. Similarly, cognitive redefinition is ineffective for some patients. Therefore, an idiographic approach is more appropriate. Cultural differences Acupuncture demonstrates alternative pain relief techniques to traditional Western drug therapy, supported by research evidence. Hu et al. (2016) found that cancer patients receiving acupuncture alongside conventional drug therapy experienced greater reduction in pain than those just having drug therapy. SKILLS BUILDER Martina suffers from chronic back pain and strong medication has only been partially successful. She is thinking of trying acupuncture. Explain one strength of acupuncture that might attract Martina. [2] You will need knowledge of the strengths of psychological pain treatments, and particularly of one strength of acupuncture for someone who is on painkillers already. NOW TEST YOURSELF 8.33Outline what is meant by reductionist with reference to biological treatments for pain. [2] 8.34 Explain two differences between biological and psychological treatments for pain. [4] 8.35 Antonio has been experiencing some side effects from his pain medication, so he has stopped taking it. But the pain is disturbing him, though it is not severe. He is afraid of needles. Suggest a treatment that Antonio could try as an alternative to medication. Explain your answer. [4] 8.36 Sherif is interested in how people manage and control chronic pain. Plan a study to help Sherif investigate this. Your plan must include details about: – type of data – ethical issues. [10] 8.4 Stress 8.4.1 Sources of stress Defining stress Stress is how our body reacts when we feel under pressure. Sarafino (2006) provides three definitions: 1 Effect of environment on individuals. 2 Bodily response to stressful events. 3 Interaction between person and environment; individuals choose their response using a combination of behavioural, cognitive and emotional strategies. Physiology of stress General Adaptation Syndrome Selye (1936) suggests three stages of his General Adaptation Syndrome (GAS): 1 Alarm: – Prepares body for fight or flight. – Cortisol, epinephrine and norepinephrine maintain the body’s increased arousal levels. STUDY TIP Use the Social Readjustment Rating Scale (SRRS) found at https:// tinyurl.com/vp4btbp6 and complete your own stress rating. Remember not to take this too seriously, as warned on the site. Think how many of the measures were not relevant to you (your divorce, death of a spouse, for example). Now look at the others. Would you rank them in the same way? This gives you some good evaluation tips for the nomothetic approach taken by this and similar scales. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 207 207 14/08/23 7:20 PM Stressor Amygdala Hypothalamus Pituitary ACTH Adrenal cortex > cortisol Adrenal medulla > epinephrine (adrenaline) and norepinephrine (noradrenaline) ▲ Figure 8.4 Alarm stage 2 Resistance: – If stress continues, the body tries to adapt. – The body resists efforts to return blood pressure and heart rate to normal by allowing high levels of these hormones. – The individual may not be showing outward signs of stress but becomes susceptible to illnesses. 3 Exhaustion: – The body cannot maintain arousal indefinitely. – This weakens the immune system. – The individual is likely to experience illness and physiological damage. Effects of stress on health Acute (short-term) stress This can be protective in terms of health. For example, if you have surgery or a vaccination, the acute stress response alongside immune system activation enhances the immune response. Chronic stress Chronic stress affects the following systems: » Digestive system: – Chronic stress changes hormone levels and increases stomach acid, which may lead to stomach ulcers. – The behavioural response to stress can cause ulcers: smoking, drinking, use of NSAIDs (ibuprofen) and lack of sleep. » Circulatory system: – Increased heart rate leads to strain on the circulatory system. – Chronic stress affects the immune system and raises coronary heart disease (CHD) risk by raising blood pressure (hypertension). – Another risk for CHD is high cholesterol levels, which can lead to blood clots and arteries narrowing. – CHD risk is raised by the behavioural response to stress: overeating, drinking alcohol and smoking. » Immune system and immunosuppression: – Chronic stress leads to immune system suppression, due to cortisol produced. – Kiecolt-Glaser et al. (1984) measured natural killer (NK) cells in American medical students’ blood a month before exams and during exams. NK cells are essential to the immune system. They found lower levels in the second sample, and even more so for those reporting loneliness and/or stressful life events. SKILLS BUILDER Stress can be explained in terms of deterministic factors. Explain two ways in which the explanations that you have learnt so far in this section are deterministic. [4] By listing all of the ways in which the physiology of stress and effects of stress on health are deterministic, you can then choose two and explain how they are deterministic. This will prepare you for the free will side of the debate later when you come to consider how people reduce their stress. Causes of stress Life events Holmes and Rahe (1967) investigated the relationship between stressful life events and illness. They developed the Social Readjustment Rating Scale (SRRS) measuring life events experienced in the last 12 months from a list of 43 (see page 212). 208 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 208 14/08/23 7:20 PM 8 Health Psychology Holmes and Rahe concluded that the more life events (positive or negative) in the previous year, the higher the likelihood of stress and ill health. Work Work can be stressful for three main reasons: » Under-stimulation: Johansson et al. (1978) studied Swedish sawmill workers and compared the finishers (preparing timber) to the sawmill cleaners. Finishers had highly repetitive work and higher stress hormone levels than cleaners. » High workload: in the same study, Johansson et al. found that finishers had a high level of responsibility and demand, and higher illness/absence than cleaners. » Low control: Marmot et al. (1997) studied 10,000 UK civil servants. They found no correlation between workload and stress, but lack of control was associated with CHD in lower grade civil servants. Relevant research: Chandola et al. (2008) Aim: to determine biological/behavioural factors linking work stress and CHD. Methodology: » A 17-year longitudinal study of 10,308 London-based civil servants aged 35–66. » Self-reported work-related stress and isolation were assessed by the Job Strain Questionnaire. » Incidents of CHD were noted. » Cortisol levels were measured on waking and 30 minutes later. » Alcohol consumption, smoking and exercise were all measured. » The study ended with a clinical examination. Results: » Self-reported work stress was lowest in the highest grades of civil service. » Among younger participants, there was a significant association between work stress and incidents of CHD. Little association was found in older participants (aged 50–60). » Higher work stress was associated with poor health behaviour. » Work stress also correlated with a morning rise in cortisol towards the end of the study. Conclusion: » Chronic work stress is a risk factor for CHD. » Approximately 32 per cent of the effect can be explained by poor health behaviours. Type A personality » Friedman and Rosenman (1974) were physicians working with male CHD patients in the USA in the 1950s. » They compared male patients’ incidence of CHD to their partners/spouses, who had a similar diet. » Partners/spouses were less likely to have CHD. » Certain behaviours associated with cholesterol levels and blood clotting time were associated with greater risk of CHD. » They called these behaviour patterns ‘Type A’ personality, characterised as competitive, ambitious, work-driven, time-conscious and aggressive. » The Type A personality was identified as a risk factor for white, middle-class men (Friedman and Ulmer, 1985). Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 209 209 14/08/23 7:20 PM ▼ Table 8.30 Methodological issues Strengths Weaknesses Reliability – Kiecolt-Glaser et al. (1984) used two objective quantitative methods, measuring NK cells and life events questionnaire. Friedman and Rosenman (1974) studied 3,154 healthy men between the ages of 39 and 59 for eight and a half years. A personality questionnaire separated them into Type A and Type B (relaxed) personalities. Almost twice as many Type A people than Type B developed CHD. This provides research evidence for the theory. Research by Johansson et al. (1978) and Marmot et al. (1997) supports Chandola et al.’s (2008) findings. Validity – cannot determine which Type A personality aspects increase individual risk of CHD. Some research suggests hostility levels are a leading factor, not personality as a whole. Usefulness – understanding the relationship between Type A personality factors and stress can help people reduce their risky attitudes and behaviour. Correlational research – data was generated mainly through self-report and was correlational. This cannot account for other factors that may be responsible for CHD. Longitudinal research – Chandola et al. used data triangulation over a long period, increasing the validity of their findings. Cultural/individual differences – Holmes and Rahe’s (1967) SRRS ignores individual/cultural differences. Issues and debates Reductionism versus holism Biological, SRRS and Type A/B personality explanations are reductionist. They try to describe complex human behaviours simplistically. Many people are a mixture of both personality types, depending on context and current stressors. A holistic approach may be beneficial as situational factors also impact people’s reaction to stress. Cultural differences The research into work causing chronic stress was conducted in Western individualist cultures. Busy, repetitive jobs with low responsibility and low control may be viewed differently in other cultures. SKILLS BUILDER Johannes is always on the go. He works hard and worries a lot, but finds consolation in eating, so he is putting on weight.

Heart rate variability (HRV) » This is the variation in time between heart beats measured in milliseconds with an electroencephalogram (ECG). » When relaxed, HRV goes up but it goes down when stressed. » Nowadays smart watches can measure HRV by detecting heartbeat optically through wave of blood flow in the wrist and sending data to the phone. Brain function (fMRI) » Functional magnetic resonance imaging (fMRI) scanners record brain activity using powerful electromagnets. » The scanner recognises changes in blood oxygenation and flow that occur during neural activity. » Degrees of neural activity are different colours on the scan, showing active brain areas. Sample tests: salivary cortisol » Cortisol released by adrenal glands as part of the ‘fight or flight’ response can be measured non-invasively in urine and saliva. » High levels of cortisol indicate that the individual is experiencing stress. Relevant research: Wang et al. (2005) Aim: to study neural circuitry of psychological stress. Methodology: » There were 32 participants: 25 experimental, 7 in control group. » Participants in the experimental group were scanned using perfusion fMRI. » There were four scans of eight minutes each, ending with a full anatomical scan. The scans: 1 Baseline condition without task. 2 Low-stress condition: participants counted backwards aloud from 1000. 3 High-stress condition: performed verbal serial subtraction of 13 from a fourdigit number aloud; prompted to go faster during the task and if they made a mistake, they had to restart. 4 Final baseline condition without task. » Control group also had four scans, but no task. » Participants in both groups completed a self-report stress scale (1–9). » Saliva samples were collected immediately before and after each scan. » Experimental participants reported level of effort, frustration and task difficulty after low- and high-stress tasks. » Heart rate was recorded every two minutes. Results: » The ventral right prefrontal cortex (RPFC) showed continued activation during and after stress tasks. » This demonstrates that perfusion fMRI is a suitable approach to measure stress. Conclusion: the ventral RPFC plays a central role in stress response.

Methodology: » During the morning commute, 208 American commuters completed five-point Likert scales reporting their stress. » Near the journey’s end, they completed a proofreading task to measure motivation/persistence. » A saliva sample of cortisol levels was taken at the end of the journey. » Crowding was measured via observation. » At the weekend, researchers visited participants’ homes and took another cortisol sample, at the same time as the workday one. The participant’s spouse/ partner was asked to evaluate interactions on a five-point rating scale, using a questionnaire. Results: » Proximal crowding significantly correlated with cortisol levels, self-reported mood and percentage of proofreading errors. » Distal crowding was not correlated with stress. » Longer commutes were associated with significantly higher cortisol levels, poorer proofreading performance and higher levels of perceived commuting stress. » Spousal ratings of commuter stress were not associated with longer commuting times. Conclusion: proximal crowding is related to commuter stress, possibly due to invasion of personal space, but distal crowding is not. Psychological measures Self-report questionnaires These are easily completed and a convenient way to measure stress. Friedman and Rosenman’s personality test » Friedman and Rosenman studied couples with the same diet and found men had a higher incidence of heart disease. » They sent 150 questionnaires to San Francisco businessmen, asking which of ten listed habits a friend had exhibited prior to a heart attack. » The questionnaires were also sent to hospital workers looking after cardiac patients. » They identified consistent traits in responses. » Structured 25-question audio-taped interviews were conducted over more than eight years, assessing how people responded to everyday pressures. » Participants’ personalities were rated by two researchers to ensure inter-rater reliability. Jenkins et al. (1979) created a pen and paper version of this personality test – the Jenkins Activity Survey. A subset of 21 items best predicted Type A behaviour: questions about being punctual and competitive. Using this, psychologists can identify an individual’s personality type as either A or B. Life events questionnaire Holmes and Rahe (1967) created the Social Readjustment Rating Scale (SRRS): » This included 43 life events based on the type of events that their patients had reported experiencing. » Holmes and Rahe asked a sample of 394 participants to rate the life events (regardless of whether it was positive or negative). They were then ranked and a score assigned. » Total scores for a 12-month period: – fewer than 150 life change units = 30 per cent chance of stress – 150–299 life change units = 50 per cent chance of stress – over 300 life change units = 80 per cent chance of stress-related illness. 212 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 212 14/08/23 7:20 PM 8 Health Psychology ▼ Table 8.31 Methodological issues Strengths Weaknesses Generalisability – the Jenkins Activity Survey is an easy-to-score self-report questionnaire; it could be completed online or sent out to large numbers of people. Generalisability – Wang et al.’s (2005) fMRI research was expensive and time-consuming, and there were just 32 participants, giving low generalisability. Validity – Scully et al. (2000) reviewed SRRS 30 years after it was first used. They reported it was still a reliable measure of life events, stress and ill health, suggesting it has temporal validity. Validity – Holmes and Rahe’s (1967) research was correlational, only looking at the relationship between health and life events. There could be other variables (like poor nutrition through stress) affecting health. Objective data – Evans and Wener (2007) measured cortisol in saliva samples; this is an objective way of measuring physiological effects of stress. Wang et al. used fMRI scans, which is a more objective and reliable way of measuring stress than self-report methods. Subjective data – self-report measures of stress or personality (Friedman and Rosenman, 1974; Holmes and Rahe, 1967) are prone to social desirability bias. Issues and debates Individual and situational explanations The scales used take an individualist approach to stress and illness, seeing the cases as lying in people’s individual behaviour. This fails to consider lifelong environmental stressors like disability or poverty. Cultural differences Research into biological and psychological measures of stress has taken a Western, individualist approach. Rating scales assume that Christmas, weddings and moving house are all highly stressful events, but this has not been tested cross-culturally. NOW TEST YOURSELF 8.41Using examples of research into measuring stress, explain what is meant by individual and situational explanations. [4] [2] 8.42Outline what is meant by temporal validity. 8.43 Explain two strengths of self-report questionnaires for measuring stress.

Rating scales for adults may not apply to younger people, for example. a Plan a study using self-reports to investigate stress in 16–18-year-old full-time students. Your plan must include details about: – question format (open and closed questions) – scoring/interpretation. [10] b Describe one piece of psychological knowledge on which your plan is based. [4] SKILLS BUILDER Suggest one strength of using biological measures of stress. [2] Identify a strength of using biological measures and explain why it is a strength. Remember just to choose one and focus on the reason for this being a strength. 8.4.3 Managing stress Psychological therapies » Biofeedback is based on operant conditioning. » It uses technology so an individual can see/hear the physiological reactions that occur when under stress. » The individual is taught relaxation techniques and connected to machines measuring muscle tension (EMG), brain activity (EEG) and sweating (SCR). » When increased activity is identified, visual/audio feedback is given. » Relaxation techniques used while receiving positive feedback decreases heart rate/tension. » The individual learns how to use relaxation techniques when stressed. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 213 213 14/08/23 7:20 PM Relevant research: Budzynski and Stoyva (1969) Aim: to describe a biofeedback instrument incorporating operant conditioning principles. Methodology: » Fifteen participants were randomly allocated to one of three groups: – Experimental group – correct feedback: participants were told the tone of EMG would vary with forehead muscle tension. They were told to relax and keep tone pitch low (high pitch = more tension). – Control group 1 – no feedback (silence): participants were asked to relax, especially forehead muscle. – Control group 2 – irrelevant feedback: participants were asked to relax deeply, especially forehead muscle, and told low monotone would help relaxation. » EMG measured muscle action potential over 20 sessions. » Participants were paid $1.50 for each session and told bonus would be given according to their rank in the group of 15. » Experimental group participants received continuous feedback about muscle activity. Results: there was a 50 per cent mean decrease in action potential in the experimental group; 20 per cent in the silent control group; and 28 per cent in the irrelevant feedback control group. Conclusion: biofeedback may be useful for people with certain psychosomatic disorders. Preventing stress Stress inoculation training There are three phases of stress inoculation training (SIT) (Meichenbaum and Deffenbacher, 1988): 1 Conceptualisation involves two goals: – building collaboration between client and trainer – increasing the client’s understanding and awareness of nature/impact of stress responses. The client is taught how to recognise stress and anxiety through the process of Socratic questioning. 2 Skill acquisition: – The client is made aware of their anxious self-talk. – They are taught specific self-statements to counter negative self-statements. – They are taught techniques like problem-solving and self-reward for coping. 3 Rehearsal and application: – This is the ‘inoculation’ part of training: clients work on transferring skills across increasingly demanding levels of stressors. – Role plays and imagery are used for assignments. – The client feeds back to the trainer. – Coping techniques are learnt. Key study: Bridge et al. (1988) Context: » Relaxation and imagery techniques can help patients to deal with the psychological stress of cancer diagnosis and treatment. » Previous research with cancer patients suggests positive thought and guided imagery can prolong life (Simonton and Simonton, 1975). Aims and hypotheses: » Aim: to see whether stress could be reduced in patients diagnosed with early breast cancer and receiving radiotherapy. » Hypothesis: women receiving relaxation training with an imagery component would show less stress than women given relaxation training alone. 214 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 214 14/08/23 7:20 PM 8 Health Psychology Research methods and design: randomised control trial using questionnaires. Sample: opportunity sample of 139 women (average age: 53, all under 70) treated either by mastectomy or lumpectomy; attending six-week radiotherapy treatment at a UK hospital. Procedure: » Participants completed the Profile of Mood States and the Leeds General Scales Questionnaire. » All participants were seen individually by the researcher, once a week for six weeks. » Participants were allocated to one of three conditions: 1 Control 2 Relaxation 3 Relaxation plus imagery. » Treatment groups were taught relaxation techniques involving diaphragmatic breathing. » The ‘relaxation plus imagery’ group imagined a ‘peaceful scene’ of their choice. » The control group women chatted together. » Sessions lasted 30 minutes. » Treatment groups had audio tapes for home practice. » Participants repeated the same questionnaires at the end of the study. Ethics: » Fully informed consent was given. » Participants were informed that results would not appear in their medical records and they would not be penalised if they refused to take part. » No drugs would be given. » Confidentiality was maintained. Results: » No significant differences were found between groups on the initial questionnaire scores. » Mood before and after the study was compared. There was no significant difference in mood disturbance of the ‘relaxation’ group; there was a small difference in the ‘relaxation plus imagery’ group; in the control group, total mood disturbance worsened. » However, when the researchers divided women into under-54 and over-54 groups, the results differed. Conclusions: » Relaxation combined with imagery is effective at reducing mood disturbances. » Mood disturbances worsen in patients with no intervention. » Intervention is more effective in older women with more time to focus on the techniques as they are less likely to be working or have young children. ▼ Table 8.32 Methodological issues Strengths Weaknesses Reliability – Bridge et al. (1998) used standardised procedures: the women in the treatment groups were taught relaxation techniques in the same way. This allows replicability. Ethics – stress inoculation training (SIT) is expensive and the cost is not covered by some countries’ health services. The number of sessions needed may require unaffordable time off work. Therefore, some people are excluded from this. Mood disturbance for Bridge et al.’s control group worsened. They needed to be offered the therapy afterwards. Application to everyday life – in Budzynski and Stoyva Generalisability – in Bridge et al., there were only 44–48 participants in each group, and fewer when broken down (1969), EMG techniques gave individuals a way of by age. This is unlikely to represent the target population. managing stress in different everyday situations. SIT focuses on stress causes, not just symptoms. The skills used in training can be applied to everyday situations. Bridge et al.’s treatment groups used audio tapes at home and could continue to do so. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 215 215 14/08/23 7:20 PM Issues and debates Determinism versus free will The research demonstrates that training helps people manage their low mood by exercising free will, reducing feelings of helplessness and increasing empowerment during difficult treatments. Mental wellbeing is determined by attitudes to treatments. Application to everyday life Relaxation techniques could be carried out at home. They are more effective with women over 54. Interventions could be targeted at older women who are most likely to benefit. NOW TEST YOURSELF 8.45Using examples of research into managing stress, explain what is meant by determinism versus free will. 8.46 Jacqui suffers from tension headaches.

(1988): a Explain how the participant’s age was relevant to the results of the relaxation training. b Explain what is meant by a ‘randomised control trial’. 8.48 Suggest one weakness of self-report methods when conducting research into managing stress. [4] [2] [2] [2] [2] SKILLS BUILDER Explain one strength of an operant conditioning technique for managing stress. [2] First, identify the technique as biofeedback and bullet-point the strengths. Choose one and write about it, explaining why it is a strength. 8.5 Health promotion 8.5.1 Strategies for promoting health Fear arousal » Fear arousal uses vivid imagery to raise public awareness of risky health behaviours, such as the use of graphic imagery on cigarette packets. » Success is more likely if the individual has a high level of self-efficacy. » If fear appeals are too anxiety-provoking, behaviour becomes defensive and people avoid the fear message or even engage more in the activity (Brown and Smith, 2007). » Janis and Feschbach (1953) found that high fear appeals lead to a high level of emotional stress and the individual may: – ignore the message – become distracted/unable to concentrate – become aggressive to the person communicating the health message – actively avoid the message. » Low fear appeals are also ignored as they do not produce the motivation to change. Relevant research: Janis and Feschbach (1953) Aim: to investigate potential adverse effects and defensive reactions to fear appeals.

This will assist in decoding exam questions and including the expected content in your answers. Methodology: » Participants were 200 American high school students (mean age: 15). » They were randomly allocated to either strong, moderate or minimal fear appeal groups on dental hygiene or a control group. 216 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 216 14/08/23 7:20 PM 8 Health Psychology » Fear appeal groups received the same essential information. » Independent variable – strength of fear appeal: – strong – serious dangers of poor dental hygiene given, using the word ‘you’ frequently – moderate – consequences of poor dental hygiene given in a factual manner – minimal – information given on the growth and functions of teeth – control – information given on the structure and function of eyes. » The effects of communication were measured in four ways: 1 A general health questionnaire on dental hygiene (a week before lectures). 2 Self-reported feedback on a five-point scale, from ‘very worried’ to ‘not at all worried’. 3 A 23-item test on the factual content of lectures. 4 A follow-up questionnaire on the effect of lectures (one week later). Results: » There was no difference in the amount of knowledge remembered. » In the strong fear group, 42 per cent thought about the condition most of the time, compared to 22 per cent in the minimal fear group. » In the strong fear group, 74 per cent felt worried about the condition of their mouth, compared to 44 per cent in the minimal fear group. » Participants in the strong fear group found the lecture more interesting than other groups. » More people in the strong fear group said there was something they disliked about the illustrated talk. » Groups’ conformity to oral hygiene behaviour: – strong fear group = 8 per cent – moderate fear group = 22 per cent – minimal fear group = 36 per cent – control group = 0 per cent. Conclusion: » Strong fear appeals create a high level of tension and concern, but little change in behaviour. » Low fear appeals result in greater behaviour change. » Level of fear appeal does not affect the amount of knowledge gained from communication. Providing information » This includes giving people information they need to stop an unhealthy habit. For example, to help people give up smoking, they could be provided with links for buying nicotine patches or details of stop smoking programmes (Sarafino, 2006). » Waiting rooms can have booklets on various diseases and illnesses tailored to the specific clinic. Home-based exercise programmes » Myocardial infarction (MI, or a heart attack) is distressing and requires the survivor and their family to adjust their lifestyle and recover psychologically. » MI rehabilitation reduces distress and improves quality of life. » Not providing programmes may lead to a loss of confidence and depression. » Home-based interventions are uncommon, despite evidence that they are as useful as hospital-based ones. Relevant research: Lewin et al. (1992) Aim: to evaluate the effectiveness of a home-based post-MI exercise programme. Methodology: field experiment; longitudinal design. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 217 217 14/08/23 7:20 PM » Three days after admission to a UK coronary care unit, 176 patients (mean age: 56) were randomly assigned to one of two groups: – Experimental group: self-help rehabilitation programme after discharge. Spouses were given information, and invited to take part and to encourage the patient. – Control group: standard care plus placebo information package and informal counselling. » Both groups were followed up at one, three and six weeks. » Postal questionnaires were sent at six weeks, six months and one year to measure symptoms of anxiety and depression, general health and use of health services. Results: » There was a significant improvement in anxiety and depression in the rehabilitation group at six weeks, six months and one year. » The control group made an average of 1.8 more visits to the doctor in the first six months compared to the rehabilitation group. » At one year, the control group had made a mean of 0.9 more visits. » More members of the control group were admitted to hospital in the first six months (24 per cent versus 8 per cent of rehabilitation group). Conclusion: self-rehabilitation programmes lead to improved psychological adjustment, fewer cases of readmittance, fewer visits to the doctor and a lower rate of anxiety and depression. ▼ Table 8.33 Methodological issues Strengths Weaknesses Application to everyday life – the fear arousal method of persuading individuals to change their behaviour is still used today in health promotion campaigns. This shows that fear appeals are useful. Lewin et al. (1992) is supported by research. Campbell et al. (1998) found an improvement in blood pressure and 28 per cent reduction in hospital admissions. Individual differences – Janis and Feschbach (1953) couldn’t completely predict how people will respond to fear appeals. Individual factors such as personality and prior experience could affect response. Validity – Lewin et al. ensured patients in the rehabilitation group did not talk to others about their intervention. They used a double-blind method so neither the cardiologist nor the nursing care team knew to which condition patients were assigned. Validity – Lewin et al.’s funding ran out; nearly half of the participants in the experimental and control groups were not followed up at the six months and one year points. This could affect the validity of long-term findings. Longitudinal study – Lewin et al. were able to investigate long-term effects of a home-based post-MI exercise programme. Ethics – fear appeals reduce the self-esteem of those unable to follow guidance, increasing the belief that they are unable to do anything to avoid negative consequences (Simpson, 2017). Issues and debates Individual versus situational explanations Research by Wu et al. (2021) looked at the effects of fear appeals during the COVID-19 pandemic using situational factors such as notification of proximity to infected person and whether this would motivate individuals to make behavioural changes. This focused on situational factors and individual factors, like how personality and prior experience affect responses. It is important for researchers to consider both factors when researching fear appeals. Cultural differences Tannenbaum et al. (2015) reviewed data from 127 cross-cultural studies on fear appeals. They found no evidence of cultural differences in effects. However, Chung and Ahn (2013) found cultural differences when researching South Korea and the USA, suggesting different culturally appropriate messages should be used. This suggests that research around fear appeals and cultural differences is conflicting, and more research is needed. 218 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 218 14/08/23 7:20 PM 8 Health Psychology SKILLS BUILDER Sylvie is designing questionnaires to investigate the efficacy of health promotion strategies. Explain one way that Sylvie could ensure that the data she collects is valid. [4] Combine your knowledge of research methods with what you have learned in health psychology. How might social desirability bias affect how participants answer a questionnaire about their response to health promotion strategies? What could the researcher do to help participants provide detailed and honest answers? The question only requires you to write about ‘one way’. Choose your best idea and explore that in detail. NOW TEST YOURSELF 8.49Outline one ethical issue with fear appeals as a method of health promotion. [2] 8.50 Xavier thinks he would like to give up smoking. His friends don’t smoke, and they are always warning him of the health risks, but that just makes him defensive. Suggest one way in which his friends may have more success, rather than relying on fear arousal. [2] 8.51 Explain what is meant by individual versus situational explanations, using research into strategies for promoting health. [4] 8.52 Plan a field experiment using questionnaires to investigate strategies for promoting health. Your plan must include details of: – question format – sampling technique. [10] 8.5.2 Health promotion Schools and healthy eating Research shows that in some countries young children do not eat enough fruit and vegetables. The UK Department of Health (2000) found that fewer than 4 per cent of children ate the recommended five portions of fruit and vegetables a day, with one in ten eating none. Relevant research: Tapper et al. (2003) Aim: to increase consumption of fruit and vegetables through the use of ‘Food Dudes’ in schools. Methodology: » A variety of studies carried out, including one in a nursery. » Researchers used a video of the ‘Food Dudes’ – a group of four children who gain superpowers from eating vegetables. » The Food Dudes battle against ‘Junk Punks’, who threaten to take over the planet by destroying all the fruit and vegetables. » Throughout the video, fruit and vegetables were eaten regularly. » Rewards were stickers, pens and erasers, given for eating the target amount of fruit and vegetables. » This modelling plus rewards approach resulted in increasing fruit and vegetable consumption that persisted at the 15-month follow-up. Extended research to a whole school programme: » Children aged 4–11 in three UK primary schools. » School staff implemented the programme: – Food Dude video – Food Dude rewards – letters from the Food Dudes encouraging children and reminding them how they get rewards – staff manual, briefing video and support materials. » Children watched videos and listened to letters being read out for 16 days. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 219 219 14/08/23 7:20 PM » Rewards were given to children for tasting target food or eating a whole portion. » A maintenance phase involved no videos but rewards and letters were used intermittently. » Two more schools were tested, one of which received the Food Dudes programme and another which acted as a control and simply received extra fruit and vegetables during the study. » Parents completed questionnaires after the study commenting on whether their child had enjoyed/benefited from the intervention. » Impact was assessed four months later. Results: » There were significant increases from Monday to Friday in fruit and vegetable consumption across all three initial schools. » More fruit and vegetables were eaten at weekends but results were not statistically significant. » In the two extra schools, the experimental school showed significant increases in fruit/vegetable consumption compared to the control school. » Increases persisted at a four-month follow-up. » Parents and teachers responded positively to the programme, suggesting children enjoyed it, but also that they were more enthusiastic when doing work with the Food Dudes theme. » There was improved attendance and increased confidence among low-achieving children. Conclusion: behaviour modification programmes can change children’s eating habits, in both the short term and the long term. Worksites and health and safety Promoting safe work practices is essential for reducing workplace accidents. South Africa recorded 32 mining fatalities in the first six months of 2021, with many other accidents. Behaviour modification methods using operant conditioning principles, like token economies, have been used to try and decrease accidents (see Organisational Psychology chapter, page 257). However, the long-term effects of these have rarely been studied. Relevant research: Fox et al. (1987) Aim: to investigate whether token economies are an effective long-term way of reducing accidents and injuries in two USA mines. Methodology: » Miners were divided into four hazard groups: from Group 1 – least hazardous jobs, to Group 4 – most hazardous jobs. » Miners who avoided lost-time and/or medically treated compensation were rewarded with monthly stamps, to be exchanged locally for goods. » Miners in hazardous jobs received more stamps for avoiding injuries than miners in less hazardous jobs. » Special payments were given to employees suggesting how to prevent serious accidents or equipment damage. » Injured miners lost monthly stamps depending on the number of workdays missed. Results: both mines showed substantial decreases in the number of days lost during the first five years of the token economy programme. Conclusion: token economies are a cost-effective way of reducing work-related injuries in mining. 220 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 220 14/08/23 7:20 PM 8 Health Psychology ▼ Table 8.34 Methodological issues Strengths Weaknesses Longitudinal design – both Tapper et al. (2003) and Fox et al. (1987) tracked changes over time and found that interventions were effective over the long term. Validity – Tapper et al.’s questionnaires gathered data about children’s fruit/vegetable consumption at home and school. Parents may have given socially desirable answers. Fox et al.’s reward incentive maybe stopped employees reporting small accidents, so they may not have actually decreased. Generalisability – Tapper et al.’s findings were replicated Generalisability – Fox et al. looked at USA mining companies. Therefore, study results may not generalise to in five schools across England and Wales. other countries and organisations. Research by Wang et al. (2015) on Chinese middle school children suggests similar interventions might be effective in other countries. Issues and debates Application to everyday life Time off work for accidents costs organisations work time, employee morale and money. If workplace token economies can decrease accidents, there is less chance of negative consequences for the employee; the cost of the programme will be lower than the benefit, making the study useful. Use of children in research When researchers work with children, they must design age and/or developmentally appropriate materials. Tapper et al.’s (2003) ‘Food Dude’ videos and rewards are an example of this. The materials were particularly important as they could have a long-term effect on the children’s health. NOW TEST YOURSELF 8.53 aOutline what is meant by longitudinal research. [2] b Explain one strength of longitudinal research, using research into workplace health and safety.

Using research into health promotion, suggest two strategies Howard could use to encourage the children to eat fruit and vegetables.

[6] b Evaluate what psychologists have discovered about health promotion, including a discussion about application to everyday life. [10] Always look at part b before you start writing. As part b refers to ‘application to everyday life’, you will need to include at least one piece of research in part a that can be evaluated in this respect. 8.5.3 Individual factors in changing health beliefs Unrealistic optimism This is the cognitive belief that negative events are less likely to happen to us than other people and that positive events are more likely to happen to us. Individuals feel invulnerable to disease and may disregard health advice and engage in risky behaviour. Relevant research: Weinstein (1980) Aims: 1 To investigate whether people believe that negative events are more/less likely to happen to them than others. 2 To investigate whether the more control people feel they have over negative events, the more they think it will not happen to them. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 221 221 14/08/23 7:20 PM Methodology: Comparative rating group: » In Study 1, a diverse group of American college students estimated their chances of experiencing particular life events compared to their classmates’ chances. » Researchers used 42 life events: 18 positive, 24 negative; randomly divided between two rating forms. » Different versions of the rating form (each listing 21 events) were handed to alternate students. Comparative rating forms: » Instructions said: ‘Compared to other students … same sex as you … what do you think are the chances that the following events will happen to you?’ » Beneath the description of each event were the choices: 100% less (no chance), 80% less, and so on – through to 90% more and 100% more (certain). Event characteristics group: » The same life events were rated by 120 female students. » They were instructed to estimate ‘the percentage probability of each event occurring to students at the university’. » Events were rated for: – controllability – desirability – personal experience. Results: » Participants’ scores were in the predicted direction on 37 out of 42 events (positive events = more likely to happen to them; negative events = less likely to happen to them). » There were some exceptions. For example, participants did not rate themselves as being significantly more likely to be ‘not ill all winter’. » There was a significant positive correlation between the positive events and the extent to which participants perceived them as being likely to happen to them. » When negative events were believed to be controllable, participants had a stereotypical view of the type of person to whom this type of event would likely occur, and they deemed themselves at less than average risk. Conclusion: unrealistic optimism appears when an event is perceived as controllable and people have some degree of emotional investment or commitment in its outcome. Positive psychology In the 1990s, Seligman started looking at happiness and wellbeing, rather than mental illhealth. This is a free will approach – we control our own lives and happiness. Pleasant life, good life and meaningful life ▼ Table 8.35 Seligman’s three components of a happy life 222 Happy life components Focuses on positive… Description Examples Pleasant life Emotions Having positive emotions and taking satisfaction from daily things Relaxing, reading, spending time with friends Good life Traits Understanding our signature strengths and using them to enhance our lives A person whose signature strength is creativity could focus on creative aspects of their job Meaningful life Institutions, such as democracy, family and free inquiry We will be happiest using our signature strengths to help make other people’s lives happier too; Seligman suggests this includes developing positive connections with others Helping neighbours, volunteering with a charity or campaigning for people in need Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 222 14/08/23 7:20 PM 8 Health Psychology Relevant research: Seligman (2004) Positive psychology: » Seligman’s article is an overview of a four-week introductory course. » It included weekly ‘real-world’ homework assignments. » Students reviewed scientific literature, focusing on: – the past – contentment and satisfaction – the present – joy, comfort and pleasure – the future – optimism, hope, trust and faith. » They learned about: – depressive realism: unhappy people are more accurate in their life perceptions than happy people – the effect of major life changes on happiness. » They practised increasing their own optimism, to increase productivity, improve physical health and lower vulnerability to depression. Homework tasks: » Gratitude night: gratitude increases happiness. Seligman organised ‘Gratitude night’ for his students, families and close friends. Students thanked them for all they had done for them. » Pleasurable day: students learnt skills of ‘savouring’ – sharing good experiences with others, through memories and mementoes. They also learnt mindfulness, by being in the moment and slowing down. They planned and carried out a ‘pleasurable day’. » Signature strengths: students completed a Values in Action (VIA questionnaire), identifying their top five strengths out of 24. They then chose a boring task and found a way of using their signature strength[s] to complete it. Meaningful life (final part of course): » Creating a family tree – students had family members complete a VIA questionnaire and interviewed them about relatives who had died. » Mentoring a younger student – with similar issues to ones they had overcome. » Writing a positive vision – for the future of humankind and their role in it. » Writing their own obituary – from the viewpoint of their future grandchildren.

The command term is ‘give’, which means you do not have to describe why rating scales are better or worse than forced/fixed-choice questions, but just describe how they differ. You could give an example of a rating scale from Weinstein’s (1980) research and show how the question would have changed if it was forced/fixed-choice. Key study: Shoshani and Steinmetz (2014) Context: » Many studies into positive psychology only look at short-term immediate effects of intervention. » This study takes a long-term approach. Aims and hypotheses: » To investigate whether participants in the positive psychology intervention group had better mental health outcomes throughout middle school compared with a control group. » To investigate if the efficacy of the intervention was moderated by any specific sociodemographic factors, including gender. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 223 223 14/08/23 7:20 PM Research method: » Longitudinal field experiment. » Mixed design: – compared intervention and wait list control groups (independent measures) – measured before and after intervention period (repeated measures). Sample: 1038 seventh to ninth graders (age: 11.8–14.7 years) from two large schools in Israel; 537 from one school = experimental group; 501 from the other school = wait list control group. Procedure: » A wide range of self-report questionnaires was used to gather quantitative data using rating scales. Intervention group: » Schoolteachers were trained in group dynamics and positive psychology throughout the school year. » A teachers’ textbook of lesson plans/activities was created to ensure all teachers delivered lessons in the same way. » Student sessions were conducted. These included activities, discussions, reading poems and stories and watching video clips. » Another part of the programme was gratitude – awareness and appreciation of the positive aspects of our lives. » An intervention group discussed five or more things for which they were grateful each week, writing gratitude letters to people who had a positive impact on their lives. Wait list control group: » Teachers continued with their social science lessons, focusing on adolescents’ issues. Ethics: by the time the intervention was introduced for the wait list control group, the oldest students would have moved on to high school. This meant the beneficial programme was withheld from some students. Results: » Both groups had slightly worse than expected mental health levels at the beginning of the study. » At the end of the study: – Intervention group: significant decreases in psychological distress and depression, and significant increases in optimism. – Wait list control group: increased poor mental health symptoms. Conclusions: intervention was effective for both low and high-risk middle school students. ▼ Table 8.36 Methodological issues 224 Strengths Weaknesses Longitudinal design – Shoshani and Steinmetz’s (2014) intervention ran for one year and students were followed up over a two-year period. This allowed monitoring of longer-term effects. Validity – Seligman’s (2004) self-report VIA questionnaire may result in socially desirable answers, decreasing the validity of the data. In Shoshani and Steinmetz, students completed the same questionnaires across two years. Students may have recognised that questionnaires measured success of the programme and provided the answers they believed teachers hoped for (participant expectations). Psychometrics – used by Weinstein (1980) and Shoshani and Steinmetz as selfreport measures. Operationalisation and standardisation of the concepts mean they can be applied objectively and research can be replicated. Generalisability – Shoshani and Steinmetz involved two Israeli middle schools. Positive psychology interventions may be less effective with older teenagers or primary school children. Weinstein’s research into unrealistic optimism sampled students from one American university. Therefore, these findings are not generalisable outside of this population.

This ignores individual explanations, such as how for some people (e.g. people who are chronically ill) acknowledging negative aspects is important for them to be able to adjust their behaviour. Cultural differences Two Israeli middle schools were involved in Shoshani and Steinmetz (2014). The results may not apply to other cultures and other types of school. NOW TEST YOURSELF 8.57 Explain what is meant by individual factors, using research into changing health beliefs. 8.58 Suggest why measures of individual factors in changing health beliefs may be culturally biased. 8.59 From the key study by Shoshani and Steinmetz (2014) on the efficacy of a positive psychology intervention programme, suggest one strength of collecting quantitative data. 8.60 Describe what is meant by meaningful life. [4] [2] [2] [2] SKILLS BUILDER Using the key study of Shoshani and Steinmetz (2014), explain two strengths of a longitudinal design field experiment as a method to investigate wellbeing. [4] The best way to approach this is to explain one strength of a field experiment and then one strength of a longitudinal design when using a field experiment.

To understand the weaknesses of such tests, try one yourself. Find examples of the Thematic Apperception Test on the internet, such as https://utpsyc. org/tatintro. Discuss your findings with others and identify two strengths and two weaknesses of this test. ▲ Figure 9.1 Maslow’s hierarchy of needs Maslow’s hierarchy of needs Maslow’s theory of motivation (Figure 9.1) can be applied to the workplace: 1 2 3 4 5 Physiological: enough wages for food and heating. Safety: pension and safe work environment. Love and belonging: accepted and have social interactions. Esteem: respected (e.g. getting promoted). Self-actualisation: can grow, challenge yourself and have autonomy. Maslow suggests you need to move up through the first four deficiency needs before you can reach the growth need of self-actualisation. Relevant research: Saeednia (2011) Aim: to develop a reliable scale to measure basic needs satisfaction in children. Methodology: » Thirteen children (with parents and educators) – open question interview about basic needs satisfaction. » Themes – participants’ wishes, supportiveness of family to child’s independence. » Coded and analysed based on Maslow’s hierarchy. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 227 227 14/08/23 7:20 PM » Constructed Basic Needs Satisfaction Scale (BNSS) based on themes. » After pilot study, BNSS distributed to 300 participants. Results: high reliability of BNSS for use with children (0.83). Conclusions: qualitative methods are more appropriate when investigating Maslow’s hierarchy due to children’s unconscious tendency to pretend that need is being met. BNSS is an indicator of life satisfaction. SKILLS BUILDER Tamara owns a small family-run cafe. She wants to ensure her staff are happy and will not leave. She researched Maslow’s hierarchy of needs theory to help her achieve this. Suggest two ways that Maslow’s hierarchy of needs theory could help Tamara ensure her staff are happy and do not want to leave. [4] A balanced answer is required giving two detailed applications of Maslow’s needs theory to Tamara’s situation. For basic physiological needs, show your knowledge of the need. For example, ‘One way Tamara could ensure staff are happy is to ensure physiological needs such as food and warmth are met.’ Apply this to the workplace. For example, ‘Tamara could achieve this by ensuring workers’ wages are enough for them to buy food and pay for heating.’ Repeat for a second need, such as belonginess or esteem needs. McClelland’s theory of achievement motivation (1961) Work-related motivational needs » There are three universal motivational needs within work. » One could dominate the others and shape work behaviours. » These can be shaped by life experiences and cultures. McClelland’s three universal work-related motivational needs 1 Need for achievement: – This is the urge to master a task. – People with high achievement needs will: – avoid easy low-reward/low-risk situations – avoid very difficult high-risk situations – make the best leaders within the workplace. – People with low achievement needs avoid work responsibility due to fear of failure. 2 Need for affiliation: – People with high affiliation needs: – desire interaction with others – conform to the group – avoid risk, preferring collaboration to competition – dislike being singled out for praise. – People with low affiliation needs: – are not team players – isolate from others – do not seek acceptance. 3 Need for power: – People with high power needs: – are suited to leadership positions – want prestige and high status. – Two types of power needs: – personal power: need to control others. – institutional power: need to organise a group to further business goals. – Most effective managers have high institutional power needs. – People with low power needs depend on others to make decisions. Thematic Apperception Test (TAT) » The TAT is a projective test to measure individual needs. » It tests imagination. Individuals are shown a series of ambiguous pictures to construct a story revealing their unconscious needs and motives. 228 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 228 14/08/23 7:20 PM 9 Organisational Psychology ▼ Table 9.1 Methodological issues Strengths Weaknesses Usefulness – Saeednia (2011) gives the basis for future research looking at children’s needs. McClelland (1961) allows employers to understand and meet workers’ individual needs. Internal validity – children may not express themselves fully, so Saeednia’s research may only measure language ability. McClelland’s research used self-reports, which is subject to social desirability bias. Reliability – Saeednia used quantitative data (from the BNSS), reliably obtained to scientifically test Maslow’s theory. McClelland used projective tests and a standardised scoring system, improving replicability. Generalisability – McClelland’s theory focused on Western workplaces. Saeednia’s participants were from a wealthy area of Tehran. Both have low generalisability. Issues and debates Cultural differences McClelland’s theory concerned males working in individualistic cultures, so it may not apply to collectivist cultures. Maslow assumes self-actualisation is universal, but collectivist and individualistic cultures may understand it differently. SKILLS BUILDER Suggest one strength of using the Thematic Apperception Test (TAT) to identify an employee’s individual needs. [2] Identify a strength of the TAT and explain why it is a strength, relating your answer to worker motivation and production increase. Individual and situational explanations McClelland only considers individual needs, not situational explanations. However, satisfied power needs mean an individual’s authority over others requires them to be submissive, so the social situation has to be right. Maslow’s theory suggests individual personality is important in determining love and belongingness in the workplace, ignoring the role of the workplace situation. SKILLS BUILDER a Describe what psychologists have discovered about need theories. [6] b Evaluate what psychologists have discovered about need theories, including a discussion on cultural [10] differences. ‘Psychologists have discovered’ does not only mean studies, but also the theories in this section. When you are describing in part a, you can use Maslow, McClelland and Saeednia, as well as the TAT. For part b, you could address the issues and debates (e.g. cultural differences). Talk about this in terms of the study and the two theories in this section. This will show the range of your knowledge. Include application to real life, individual and situational explanations, and validity. NOW TEST YOURSELF 9.1 Jeremiah’s results on the Thematic Apperception Test (TAT) suggest he has a high need for affiliation. Suggest two behaviours Jeremiah may show in the workplace because of this. 9.2 Explain two weaknesses of need theories. You must refer to individual and situational explanations in your answer. [2] [4] 9.3Research that aimed to construct a reliable test of Maslow’s hierarchy of needs in children has been criticised as lacking validity. Explain one reason why this research may lack validity. [2] 9.4 Explain two ways need theories could be applied to the workplace. [4] 9.1.2 Cognitive theories of motivation Locke and Latham’s (1990) goal-setting theory Goal setting involves looking at what you want to achieve and devising a realistic plan. Locke suggested an effective goal is specific and measurable (SMART). Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 229 229 14/08/23 7:20 PM SMART goals are: » Specific – well defined » Measurable – using criteria to track progress » Achievable – realistic and with resources to achieve it » Realistic/relevant – a beneficial fit with wider life goals » Time bound – have a start and end date. Locke and Latham outlined five goal-setting principles: 1 2 3 4 5 Clarity: need clear goals Challenge: need challenging goals linked to rewards Commitment: workforce must be invested in the goals Feedback: regular feedback to maintain focus Task complexity: timescales are realistic, with sub-goals Vroom’s (1964) expectancy (VIE) theory » Individual motivation at work can be affected by expectations of future events. » Behaviour results from people’s rational choices. » Any decisions look at potential rewards and potential costs of an action/behaviour. » There is less motivation if a task requires time and effort for little reward. Vroom believed performance is based upon individual factors like personality, ability and experience, and effort, motivation and performance are linked. Individuals, therefore, will be motivated if they believe that: » there is a positive correlation between effort and performance » good performance leads to a desirable reward which satisfies a need, making the effort worthwhile. The theory is based upon three beliefs which affect motivation: » Valence: personal worth of an expected reward. » Instrumentality: whether you believe your good performance will lead to an expected outcome/reward equal to the effort you put in. This can be affected by: – trust in those deciding the outcome/reward – complexity of the process of deciding the reward – clarity of the relationship between performance and outcome. » Expectancy: the perception that effort will lead to the intended performance outcomes/reward. This can be affected by the level of skill possessed, the right resources and information, and level of support from others. Therefore, increased training may improve levels of expectancy. Vroom’s formula for motivation level: motivation = valence x instrumentality x expectancy If any of the three beliefs is low, then motivation will be low. However, valence (value of reward) is the most important, so if the reward is low, then motivation tends to be low. ▼ Table 9.2 Methodological issues 230 Strengths Weaknesses Reliability – goal-setting theory is supported by over 50 years of empirical research, suggesting high reliability. Ethics – collective agreement is needed on what is ‘realistic’, or goal setting may result in decreased motivation and distress for workers. Usefulness – Locke and Latham’s (1990) and Vroom’s (1964) theories may improve workplace experience for workers by letting managers plan for a specific task and ensure rewards/outcomes are explicit and targeted. Applications to everyday life – Vroom’s expectancy theory assumes people make rational choices. This may not be the case with short-term needs; personality may have an effect. SKILLS BUILDER Outline one cognitive theory of motivation in the workplace. [2] Ensure you use a cognitive theory of motivation. Pay attention to the command word (outline). You do not need a lot of detail, or any evaluation. You should be writing no more than two or three sentences. SKILLS BUILDER Suggest one reason why expectancy theory may not be applicable to all cultures. [2] A suggestion such as ‘rewards may not be applicable to all cultures’ is brief and you could elaborate further. To develop your answer, suggest that expectancy theory assumes both collectivist and individualistic cultures are motivated identically. However, rewards/ expectation of rewards may be more important in individualistic cultures than in collectivist cultures that are more concerned about the group. Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 230 14/08/23 7:20 PM 9 Organisational Psychology Issues and debates Reductionism versus holism Both theories are reductionist, suggesting motivation is due to cognitive factors and not factors such as physiological needs or past experiences. Determinism versus free will The theories are deterministic. Expectancy theory suggests motivation is determined by expectation concerning an action’s rewards and costs; goal-setting theory suggests motivation is determined by the types of goals set, ignoring free will. SKILLS BUILDER Locke and Latham suggest SMART goals are more effective in increasing motivation than general goals. Plan an experiment to investigate the effectiveness of SMART goals versus general goals in increasing motivation in the workplace. Your plan must include details about: » sampling technique » a directional or non-directional hypothesis. [10] Paper 4 contains mandatory questions asking you to devise a study based upon theories/studies you have learnt. You could include specific features of experiments (see page 57). Identify the type of experiment, your IV/DV, any controls and the experimental design (matched pairs/independent/ repeated measures). Include details about sampling technique and hypothesis. You could also suggest where your study will take place, what time of day, etc. The procedure needs to be clear and replicable. NOW TEST YOURSELF 9.5 Janice has told her staff that their most important goal is to increase sales of coats at ‘some point soon’. Her staff tell her that this target may not be very effective as it is too general. Suggest two ways that Janice could make her goals more effective. [2] 9.6 Suggest two ways that Vroom’s expectancy theory could be used to improve motivation in the workplace. [4] 9.7 Explain one way that cognitive theories of motivation may be suggested to be [2] reductionist. 9.8 Explain one strength and one weakness of cognitive theories of motivation. [4] 9.1.3 Motivators at work Extrinsic motivators at work » Behaviour is driven by external factors through operant conditioning. The use of rewards (money) and punishments (pay cuts) increase/decrease the likelihood of a behaviour. » Employees see the direct results of their behaviour, which increases motivation. » This can be short term and lead to burn out and demotivation if it is only used to get results. Types of extrinsic motivation at work: 1 2 3 4 Pay Bonuses Profit sharing Performance-related pay Intrinsic motivators at work » Behaviour is driven by internal emotions (e.g. feeling satisfied when reaching targets). » Recognition is gained from management or praise from others. » Intrinsically motivated behaviours come from a feeling of being valued and a sense of belonging. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 231 231 14/08/23 7:20 PM Types of intrinsic motivation at work: 1 2 3 4 5 Recognition Praise Respect Empowerment Sense of belonging Deci and Ryan’s (1985) self-determination theory Two key assumptions: 1 A need to grow drives behaviour: – People are always looking to improve, to meet a challenge = intrinsic motivation. 2 Autonomous motivation is important: – Self-determination theory focuses mostly on intrinsic motivation, but acknowledges humans can be extrinsically motivated by money and fame. – If behaviour is fully self-determined, then it will be intrinsically motivated and done for internal satisfaction. – If behaviour is non-self-determined, the task just has to get done with no pleasure, little choice and no autonomy. The three basic needs for intrinsic motivation are: 1 Autonomy: self-governance and independence 2 Relatedness: building relationships with others 3 Competence: having the right qualities and skills for a task. SKILLS BUILDER Tomas overhears a conversation between his employees complaining about the pressurising daily targets, and about their critical and controlling team leader. Tomas has been reading about selfdetermination theory and concludes that all three basic needs have not been met for his employees to be intrinsically motivated. Using self-determination theory, suggest two basic needs that have not been met, giving examples from the scenario. [4] This tests your knowledge of the three basic needs of self-determination theory and your ability to link knowledge to the scenario. Read this question carefully. Use two needs from self-determination theory. Do not see the words ‘intrinsically motivated’ and talk about praise and respect as this would be inaccurate. Autonomy, relatedness and competence would all be appropriate here. Key study: Landry et al. (2019) Context: monetary rewards are extrinsic motivators, but: » if given positive functional meaning, psychological needs are met, and motivation and performance increase » if viewed as controlling rewards, psychological needs are not met, and motivation and performance decrease. Aims and hypotheses: » Aim: to explain the effect of monetary reward on employees’ motivation and performance. » Hypotheses: 1 Presenting rewards in an informational (autonomy-supportive) way leads to greater performance; presenting them in a controlling (autonomy-threatening) way leads to lower performance. 2 The effect of informational rewards on performance is mediated by greater psychological need satisfaction, leading to higher intrinsic motivation; the effect of controlling rewards on performance is mediated by greater psychological needs frustration, leading to higher extrinsic motivation. 232 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 232 14/08/23 7:20 PM 9 Organisational Psychology Research method(s) and design: » Research method: experiment. » Design: independent measures. » Data collection technique: performance on anagram-solving task; self-report questionnaires. Variables: » Independent variable: informational or controlling paragraph. » Dependent variables: – performance on 25 four-letter anagrams – seven-point Likert-scale rating of how well psychological needs had been satisfied or how strongly frustrated – seven-point Situational Motivation Scale measuring intrinsic and extrinsic motivation. Controlled variables: three-point scale rating on how valuable the reward was personally; scale rating of individual positive and negative affect (mood) resulting from the experiment. Sample: volunteer sample of 123 Canadian students (mean age: 20 years, 60 per cent female). Procedure: » Participants read their allocated instruction paragraph about the task and reward. » They were given two minutes to solve anagrams. » Participants completed the Likert scale and Situational Motivation Scale. » They rated the personal value of the reward and their affect (mood) resulting from the experiment. Ethics: » Informed consent was given by all participants and no deception was used. » Confidentiality was maintained and there was no suggestion of psychological harm. Results: » Hypothesis 1 supported: participants in the informational condition scored significantly higher on anagram-solving (0.76) than participants in the controlling condition (0.54). » Hypothesis 2 mainly supported: – Participants in the informational condition had significantly higher psychological needs satisfaction (5.79) than those in the controlling condition (5.39). – Participants in the controlling condition had higher needs frustration (2.83) compared to those in the informational condition (2.41). This predicted greater extrinsic motivation. – In the informational rewards condition, greater psychological needs satisfaction predicted higher intrinsic motivation and also better performance. – In the controlling rewards condition, psychological needs frustration increased extrinsic motivation, but the extrinsic motivation was not linked to performance. Conclusion: rewards presented in an informational way lead to: » increased performance on tasks » increased needs satisfaction, leading to intrinsic motivation and better performance, due to more engagement in the rewarded activity. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 233 233 14/08/23 7:20 PM ▼ Table 9.3 Methodological issues Strengths Weaknesses Validity – Landry et al.’s (2019) two after-test ratings scales controlled for individual differences in motivation and affect arising from the task. Cultural differences – Deci and Ryan (1985) and Hagger et al. (2013) found different aspects of motivation important to different cultures. Landry et al. used participants from the same course at one Canadian university. Reliability – Deci and Ryan reviewed 128 experiments investigating the effect of extrinsic rewards on intrinsic motivation. Supporting evidence increases reliability. Landry et al. used objective, quantitative self-report data and an overall performance score, allowing statistical tests to be used. Ecological validity – Deci and Ryan’s theory does not consider how individuals may react differently in real life. Landry et al.’s study lacks mundane realism, lowering ecological validity. Issues and debates Reductionism versus holism Suggesting that performance is dependent on self-determination, without considering the effects of personality, pre-existing competence, experience and age, is reductionist. Idiographic versus nomothetic Landry et al. (2019) was an experiment – a nomothetic method providing general rules of behaviour from the results. This could be criticised for not considering individual factors such as personality, life experiences and culture. NOW TEST YOURSELF 9.9Outline one form of extrinsic motivation. 9.10 Simone has been researching intrinsic and extrinsic motivation and believes that using intrinsic motivation would be motivating for her workforce. Outline two forms of intrinsic motivation that Simone could use. 9.11 Explain two weaknesses of theories on motivators at work. 9.12 Explain how operant conditioning theory could be applied to motivation at work. [2] [4] [4] [4] SKILLS BUILDER Describe the study by Landry et al. (2019) on applying self-determination theory to motivational rewards. [6] You have nine minutes to answer sixmark questions so practise summarising key studies to approximately 200 words. As the command term is ‘describe’, the question is assessing knowledge and understanding only; therefore, strengths and weaknesses are unnecessary. 9.2 Leadership and management 9.2.1 Traditional and modern theories of leadership Universalist theories Great person theory This is a nineteenth-century theory from Thomas Carlyle, who believed that leaders are born, not made. Charismatic leadership theory Charismatic leaders are popular, communicative and inspirational, and expect the highest standards of themselves and others. Transformational leadership theory Transformational leaders inspire positive change in their followers, increasing motivation and performance through linking their sense of identity to the organisation. 234 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 234 14/08/23 7:20 PM 9 Organisational Psychology Warrilow (2012) identified four characteristics of transformational leaders: 1 2 3 4 Idealised influence: being a role model Inspirational motivation: a vision that appeals to followers Intellectual stimulation: challenging and encouraging creativity in followers Personal and individual attention: extent to which the leader attends to individualised needs and mentors followers. Behavioural theories of leadership Behavioural theories believe leadership can be learned rather than being inborn or inherited. Ohio University behavioural explanations Researchers at Ohio University developed the Leader Behaviour Description Questionnaire (LBDQ) to investigate behaviours exhibited by leaders, by questioning followers in the military, education and industry, using a five-point rating scale. Results identified two clusters of behaviour: » Initiating behaviours (structural): the leader sets expectations as performance standards, gives feedback, emphasises the importance of goals and coordinates group work tasks. Gives certainty for employees but can limit worker autonomy and result in punishment of those who do not meet targets. » Consideration behaviours (nurturing): the leader listens to employees, treating them as equals, showing empathy and supporting them. This increases trust in the team, and the leader looks for areas where individual members can grow and improve. These behaviours are independent of each other, and a leader could be high or low in both. Usually a leader high in both behaviours is very effective; those who are high in consideration behaviours and low in initiating behaviours are the least effective. Michigan University behavioural explanations Michigan University researchers looked at the impact of leader behaviour on small groups, formulating a questionnaire similar to the LBDQ. Researchers identified two different types of leadership behaviour, independent of each other: » Production orientation: the leader sees workers as a means of fulfilling the technical and production goals of the job. » Employee orientation: the leader values workers and ensures their needs are met. Unlike the Ohio University research, the Michigan University researchers suggested high employee orientation was most effective. Heifetz’s six principles in meeting adaptive challenges Adaptive challenges arise when beliefs and values are challenged and competing values and perspectives emerge. Ways of working sometimes need to change for an organisation to develop. This is difficult for leaders because: » workers have to adapt and change, learning new roles and having new responsibilities » it can be distressing and often workers want leaders to take all responsibility. However, this expectation has to be unlearned. Leaders have a responsibility to ask tough questions, show workers the reality of the situation and challenge issues that arise. Heifetz and Laurie (1997) identified six principles of adaptive leadership: 1 ‘Get on the balcony’: step back and take an objective view from a distance to see the big picture. 2 Identify the adaptive challenge: identify and respond to the challenge effectively. STUDY TIP If you like talking things through, why not create a collaborative spreadsheet with classmates or online contacts. If you each fill in your areas of expertise, you can use the information to identify your own strengths and weaknesses, and match with a partner who can help you, as you help them. Add rows to your spreadsheet for describing and evaluating; you could be an expert on the details of a key study like Landry et al. (2019) but still struggle to make strong evaluation points. SKILLS BUILDER Evaluate the three universalist theories, including a discussion about individual and situational explanations. [10] Think about the individualist nature of the three universalist theories that see leadership qualities as properties of the individual and not of the situation. What are their strengths and weaknesses? You could contrast these theories with behavioural theories, but ensure you refer throughout to individual and situational explanations (see ‘Issues and debates’ at the end of this section). Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 235 235 14/08/23 7:20 PM 3 Regulate distress: allow views to be expressed; manage conflict and have a steady presence in the workforce. 4 Maintain disciplined attention: confront different values, beliefs and habits, allowing all voices to be heard. 5 Give the work back to the employees: support the workers in taking initiative to problem-solve. 6 Protect voices of leadership from below: listen to and protect whistleblowers and creative deviants, as they can demonstrate a fresh approach to change. ▼ Table 9.4 Methodological issues Strengths Weaknesses Usefulness – behavioural explanations suggest leaders can be trained to be more effective, and be appointed for specific behaviours. Heifetz and Laurie’s (1997) principles can be applied in an organisation to meet adaptive challenges. Generalisability – the Ohio and Michigan universities are based in the USA; Heifetz’s model focuses on Western workforce organisation; findings may not apply to all cultures. Reliability – there is real-life support for great person theory, as leaders often become leaders without any training. Charismatic leadership theory is supported by quantitative studies. Heifetz’s principles are applied successfully in healthcare, educational and military settings. Ethics – Stevens et al. (1985) found that transformational leadership can lead to emotional stress and work conflict, which could make it unethical. Similarly, imposing adaptive leadership in cultures where the workforce is looking for clarity and guidance may cause workers uncertainty and stress. Issues and debates Individual and situational explanations Universalist and behavioural theories of leadership do not consider situational explanations. Adaptive leadership takes situational aspects of the workplace into account, such as changing situations that lead to adaptive challenges and changes in individual leadership behaviour. Nature versus nurture Great person theory suggests only those born with leadership characteristics can become great leaders. This ignores the role of leadership training and fails to explain why some who seem born for leadership do not become leaders. The other theories sit more on the nurture side of the debate. NOW TEST YOURSELF 9.13 Aisha works in an organisation that has experienced challenges from competitors recently and needs to adapt its working practices. She is meeting with colleagues who are resistant to change to discuss how best to meet these adaptive challenges. Using Heifetz’s six principles of adaptive leadership: a Describe which one of these principles she may follow in the meeting. [2] b Explain why this principle may help her to overcome the resistance [2] to change in order for the organisation to grow. 9.14 Explain why universalistic theories of leadership are more individualist than other theories of leadership. [4] 9.15 Self-report questionnaires are sometimes used to gather data on leadership qualities. Using an example from a behavioural theory, explain two weaknesses of this method. [4] 9.16 Evaluate traditional and modern theories of leadership.

As an organisation adapts and matures, there is often a gradual movement from directive autocrat to permissive democrat. Scouller’s levels of leadership Scouller (2011) identified four dimensions of leadership: 1 Motivating purpose: setting a purpose that inspires people to work together collaboratively and willingly towards a goal. 2 Task progress results: checking pace and quality of progress towards the goal. 3 Upholding group unity and spirit. 4 Attending to individual effectiveness. These can only be achieved through working on three leadership levels at the same time (the 3Ps). ▼ Table 9.5 Scouller’s levels of leadership Public » Setting the vision » Ensuring unity of purpose » Achieving the group task » Building trust and a sense of togetherness » Creating peer pressure to ensure high performance standards Private » Attending to individual task behaviours, through appraisal, discipline and review » Relationship building and assessment of people’s talents, competence and commitment Personal » Technical: time management, individual and group psychology » Attitude: believing people are important and gaining their trust » Self-mastery: self-awareness and connecting with own values to serve those you lead Key study: Cuadrado et al. (2008) Context: » Eagly et al. (1992) found that female leaders obtained poorer evaluations than males if they adopted stereotypically male leadership styles when their evaluators were men. » Men did not gain poorer evaluations than women if they adopted stereotypically female leadership styles. » This led to development of the role congruity theory of prejudice towards female leaders. Aims and hypotheses: » Aim: Cuadrado et al. investigated whether women who occupy leadership roles are evaluated less favourably than men when they adopt male leadership styles. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 237 237 14/08/23 7:20 PM » Hypotheses: 1 Female leaders will receive less favourable evaluations than male leaders when they adopt male leadership styles. 2 Male leaders will not receive less favourable evaluations than female leaders when they adopt female leadership styles. 3 Female leaders will receive worse evaluations from males than from females. 4 Male leaders will receive similar evaluations from both males and females. Research method(s) and design: » Research method: experiment. » Design: independent measures; 2x2 design (male vs. female leadership style; male vs. female leader). » Data collection technique: structured questionnaire using rating scales. Variables: » Independent variables: – female leader/male leadership style – male leader/male leadership style – female leader/female leadership style – male leader/female leadership style. » Dependent variable: 14 adjectives (seven positive and seven negative) selected from previous research. Controlled variables: random allocation of participants to conditions, to reduce participant variability; standardised narrative for all participants; standardised rating scales for all participants. SKILLS BUILDER Explain two ways that Scouller’s theory of leadership could be applied in an organisation. [4] One way could relate to feedback from workers on a leader’s public leadership level and another way could relate to reflection by leaders during appraisal, on their private leadership level. The command term here is ‘explain’, so give detail and examples in your answer. Procedure: » Participants read a description of a leader’s behaviour in a hospital emergency service setting where doctors are stereotypically male and nurses stereotypically female. » They were told to imagine they were part of this service. » They anonymously rated the degree that the 14 adjectives applied to a supervisor trying out for a job, using two seven-point rating scales – one for leadership capacity and one for effectiveness. Ethics: participants received credit for completion, so they may have felt that they could not withdraw. Results: ▼ Table 9.6 Means of leader’s sex, leadership style and their interactions on adjective list, leadership capacity and leadership efficacy Dependent variables Adjective list Leadership capacity Leadership efficacy Leader’s sex Male Female 4.92 4.76 4.87 4.90 4.73 4.74 Leadership style Stereotypically Stereotypically male (SM) female (SF) 4.32 5.51 4.00 5.48 4.21 5.41 Sex x style interaction Male Female Male SF SM SM 4.30 4.34 5.55 3.83 4.17 5.63 4.18 4.21 5.52 Female SF 5.47 5.36 5.33 » Hypothesis 2 was supported. » Hypotheses 1, 3 and 4 were not supported.

Validity – Muczyk and Reimann’s theory ignores individual differences in how workers respond and the personal characteristics of leaders. Cuadrado et al.’s (2008) rating scales do not allow researchers to investigate reasons for results, especially those that did not support the hypotheses. Ethics – in Cuadrado et al., confidentiality was maintained Ecological validity – Cuadrado et al. was a narrative and there was no potential for harm as it was a narrative account task and anonymous evaluation may not task with no consequences for the supervisor or worker. accurately reflect workplace dynamics. Reliability – Cuadrado et al. used a standardised procedure with rating scales, producing objective quantitative data; can be easily replicated. Issues and debates Application to everyday life Female management styles were evaluated more highly than male leadership styles – this can be applied in training. Reductionism versus holism Leadership effectiveness and capacity were broken down into rating scales and adjectives. This does not give insight into individual reasons behind ratings and is reductionist. NOW TEST YOURSELF 9.17Outline what is meant by reductionism, using an example from leadership style. [2] 9.18 Ahmed is starting on a leadership training course preparing him for a new role in his organisation. The course will be using Scouller’s levels of leadership model as its framework. Describe two skills that Ahmed may be asked to focus on from the public level of leadership. [4] 9.19 From the key study by Cuadrado et al. (2008) on leadership styles and gender, suggest one strength and one weakness of the use of rating scales to measure the dependent variables. [4] 9.20 Suggest how an organisation looking to recruit more females into leadership posts might use the findings of Cuadrado et al. [4] SKILLS BUILDER Describe Cuadrado et al.’s research (2008) on leadership styles and gender. [6] You have nine minutes to answer sixmark questions, so practise summarising key studies to approximately 200 words. As the command term is ‘describe’, the question is assessing knowledge and understanding, so strengths and weaknesses are unnecessary. Focus on giving a detailed and accurate answer. 9.2.3 Leaders and followers Kouzes and Posner’s Leadership Practices Inventory Kouzes and Posner (2017) identified five practices of exemplary leadership, developing a Leadership Practices Inventory (LPI) to measure these. 1 2 3 4 5 Model the way: leaders set an example for others to follow. Inspire a shared vision: leaders enlist others in their plans. Challenge the process: leaders seek change and ways to improve the organisation. Enable others to act: leaders foster collaboration and build teams. Encourage the heart: leaders keep hope and determination alive. Rewards are shared. The Leadership Practices Inventory (LPI) » This is a questionnaire containing six behavioural statements for each practice (30 in total). » The leader completes the LPI-Self. Five to ten other people complete the LPIObserver, about the leader. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 239 239 14/08/23 7:20 PM » The sets of scores are compared. » Typical statements include: 19 Supports the decisions that people make on their own (enable). 25 Finds ways to celebrate accomplishments (encourage). 27 Speaks with genuine conviction about the higher meaning and purpose of work (inspire). Supporting research Kouzes and Posner (1993) involved 2876 managers and observers from a wide variety of organisations and found results from the self and observer were identical in terms of rank order. There were no significant differences between genders, and the type of organisation did not significantly affect the scores. SKILLS BUILDER Kristoff is a human resources manager at a hotel and has always used psychometric testing when interviewing to hire staff. He wants to add a more qualitative method to increase the data on possible hires. Suggest another method he could use, and give one strength of it. [4] Think first about a weakness of psychometric testing, and then decide which qualitative method would best address this weakness. Focus on exactly how the qualitative method would enhance Kristoff’s understanding of his potential employees. Followership Kelley (1988) identified two key features of good followers: » independent critical thinking, as contrasted with dependent uncritical thinking » whether the follower has active or passive participation in working towards goals. These two dimensions result in five different followership styles: 1 Exemplary: think for themselves, have positive energy and are actively engaged. 2 Alienated: mainly negative, think for themselves but do not contribute to the positive direction of the organisation. 3 Passive (‘sheep’): passive in their thinking and engagement and motivated by their leader not themselves. 4 Conformist (‘yes people’): passive in their thinking and engagement but generally positive and on the leader’s side. 5 Pragmatic: show minimal independent thinking and only get involved when they see the direction in which a situation is heading. ▼ Table 9.8 Methodological issues Strengths Weaknesses Reliability – Kouzes and Posner’s (2017) LPI rating scales Validity – Kouzes and Posner’s psychometric tests may produce objective and reliable quantitative data on the be subject to social desirability bias, affecting the five practices of exemplary leadership. Empirical support performance of the practices’ measures, lowering validity. gives Kelley’s (1988) theory greater reliability. Research evidence supports the idea that exemplary followership leads to higher performance. Usefulness – the results of Kouzes and Posner did not show gender or social desirability bias, and they suggest that LPI is applicable across organisations. Kelley’s theory can be applied when recruiting and training, giving organisations some idea of how effective followership can be obtained. Generalisation – some of Kelley’s followership styles may not be generalisable to all cultures. Those that involve ‘thinking for themselves’ only apply to more individualist cultures. Issues and debates Cultural differences Oyetunji (2013) studied lecturers in Botswana universities who self-reported their followership style and their perception of their own job performance. The research 240 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 240 14/08/23 7:20 PM 9 Organisational Psychology found that passive followers (not exemplary followers) saw themselves as the best performers. This could be due to cultural differences in what is viewed as a good follower. Idiographic versus nomothetic The theory does not take individual differences into account so it is nomothetic, generating key features and styles of all followership that it aims to apply to all organisations. SKILLS BUILDER a Describe what psychologists have discovered about the psychology of leaders and followers. [6] b Evaluate what psychologists have discovered about the psychology of leaders and followers, including a discussion about idiographic versus nomothetic approaches. [10] Look at part b before you start writing. As it refers to ‘idiographic versus nomothetic approaches’, you will need to include at least one piece of research in part a that can be evaluated in this respect. The study does not need to have taken both approaches; you could discuss how the findings would differ if another type of approach had been taken. NOW TEST YOURSELF 9.21 Zain’s friend at work has been studying about followership behaviour and has said that Zain uses an ‘alienated follower’ style. a Suggest characteristics that Zain may be showing that led to his friend’s suggestion. [2] b Explain which followership style would be better for Zain to show for him to be a good follower. [2] 9.22 Explain why an understanding of cultural differences is important in research into followership. [4] 9.23Research into followership has sometimes been criticised for being reductionist. Using Kelley’s theory, explain what is meant by reductionism. [2] 9.24 Explain two weaknesses of the use of psychometric tests to study leadership. [4] 9.3 Group behaviour in organisations 9.3.1 Group development and decision-making STUDY TIP Rating scales are commonly used in organisational psychology research. Try designing your own rating scale to measure something you are interested in – maybe your revision progress. Test it on three or four friends. This is a good way to learn about the strengths and weaknesses of rating scales. Tuckman and Jensen’s (2010) stages of group development Tuckman (1965) reviewed 55 articles studying small group development and identified four common concepts that he used as the basis of his original group development model: forming, storming, norming and performing. In 1977, Tuckman and Jensen added a final stage – adjourning. Tuckman and Jensen (2010) represent the latest five-stage model. Individuals come together Develop and present ideas; some can cause conflict Forming Storming Try to agree a strategy Norming Function as a team Performing Goals accomplished; group moves apart Adjourning (1977) ▲ Figure 9.2 Tuckman and Jensen’s (2010) model of group development Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 241 241 14/08/23 7:20 PM SKILLS BUILDER Elisa is part of a team considering using an AI tool to market the organisation’s service to customers. The team has only just been formed and represents a diverse range of opinions on, and experience with, AI tools, from almost none to AI tools developers. Using Tuckman and Jensen’s (2010) model of group development: a Describe the decision-making stages that the team will move through before adjourning after the task is completed. [6] b Explain which stage may be most challenging for them, giving two reasons for your answer. [4] Knowledge (part a) and application (part b) of Tuckman and Jensen’s model is required. For part a, give a full description of each stage and contextualise to Elisa’s marketing team. To answer part b, choose two statements from the description given and relate each to the stage chosen as an explanation for why this stage will be most challenging for Elisa’s team. Belbin’s (1981) nine team roles Belbin used observation of group dynamics and psychometric testing to develop his nine individual team roles. » Thought-related roles: – Plants: propose new ideas and approaches. – Monitor-evaluators: analyse and evaluate all options. – Specialists: get the job done. » People-related roles: – Co-ordinators: are mature and confident; make good chairpersons. – Resource investigators: explore opportunities and develop contacts. – Team workers: are diplomatic and good negotiators. » Action-related roles: – Shapers: challenge the team to improve. – Implementers: get things done efficiently. – Completer-finishers: ensure project completion according to the deadline. To measure these, Belbin constructed the Belbin Self Perception Inventory, a forced-choice questionnaire. With this questionnaire, he also developed observer statements to be used with six other people, which are not forced-choice. These six responses are correlated to measure the validity of the inventory. Faulty decision-making Groupthink The term groupthink (Janis, 1971) is used to understand why group members continue with an obviously wrong decision or course of action. Explanation: » The desire for agreement becomes powerful, replacing objectivity. » Group norms suppress critical thinking. » Group pressures to conform discourage objections. » The group sometimes has no outside information to help make decisions. Social norms: » Conformity increases as group cohesiveness grows and suppresses conflict. » Members may think a proposal is a good one but have not examined it properly. » Some may have doubts but ignore them and agree with the group. Stress: » The group shares the same values, so strong psychological pressure is created. » A crisis situation encourages groupthink. Eight features of groupthink 1 Illusion of invulnerability: over-optimism and risk-taking. 2 Rationale: members rationalise their beliefs, ignoring warnings. 242 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 242 14/08/23 7:20 PM 9 Organisational Psychology 3 Morality: members believe that their group has high morals and so ignore the moral consequences of decisions. 4 Stereotypes: members have stereotypical beliefs of outgroups. 5 Pressure: members apply pressure to anyone who expresses doubts. 6 Self-censorship: members avoid expressing opinions that deviate from the group opinion. 7 Illusion of unanimity: the assumption that anyone who remains silent agrees with the group. 8 Mindguards: people in the group who guard members from outside arguments that may break the consensus. Strategies to avoid groupthink » Invite outside experts or senior managers to meetings to challenge the ideas of the group members. However, not everyone may express their views fully or be honest. » Have a member play ‘devil’s advocate’ and go against the majority view to challenge ideas and get justification of decisions. » Have senior managers inform group members that they are all equally responsible for the decisions being made, to reduce illusions of invulnerability. » Each group member is assigned the role of critical evaluator with priority to air doubts. SKILLS BUILDER DeAnna is leading a group aimed at improving productivity among shop-floor workers. She started by feeling positive, but the more meetings they have, the more the other group members are convincing her that this project cannot work. They seem to have a stereotypically negative view of the other workers. Explain one strategy DeAnna could use to counteract this groupthink. [2] This will need knowledge of the theory of groupthink and strategies to overcome it. Focus on one strategy for overcoming groupthink and explain it clearly in relation to DeAnna’s aim of improving productivity amongst shop-floor workers. Forsyth’s cognitive limitations and errors In his book Group Dynamics, Forsyth (2006) discussed the three general categories of potential biases first identified by Kerr et al. (1996): 1 Sins of commission (acting on false information): – Belief perseverance: inaccurate information is relied on. – Sunk cost bias: group is reluctant to change their decision because they have invested money or time. – Extra-evidentiary bias: information is used when group has been explicitly told to ignore it. – Hindsight bias: overestimating the accuracy of prior knowledge of an outcome. 2 Sins of omission (ignoring useful information): – Base rate bias: ignoring relevant information about general trends. – Fundamental attribution error: stressing dispositional (personality) causes for people’s behaviour and ignoring situational factors. 3 Sins of imprecision (using heuristics that oversimplify): – Availability heuristics: basing a decision just on available information. – Conjunction bias: failing to realise that the probability that two events occur together is always going to be less than only one of the events occurring. – Representativeness heuristics: relying heavily on factors that seem initially to make sense but are misleading. Strategies to avoid cognitive errors » Educate yourself on cognitive errors in order to understand why they occur. » With fundamental attribution error, think of times when situational factors caused behaviour. » Ensure the group is diverse and that the leader’s appointment will not overpower the group. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 243 243 14/08/23 7:20 PM ▼ Table 9.9 Methodological issues Strengths Weaknesses Validity – Tuckman and Jensen’s (2010) model has changed with the times to include a final stage, showing flexibility, increasing the theory’s validity. Reliability – Tuckman and Jensen’s model lacks empirical evidence, being based mainly on theoretical articles rather than studies. Reliability – Belbin (1981) used observations to construct his theory, with self-reports and observer reports to measure individuals’ team roles. Triangulation of quantitative methods increases reliability of the findings. Forsyth’s (2006) theory of cognitive errors is supported by empirical research, increasing its reliability. Validity – Belbin’s forced-choice self-reports are subject to social desirability bias, and do not allow reasons for answers. Observer reports could be subject to situational variables. Groupthink empirical support often comes from retrospective case studies, subject to bias and faulty memory. Usefulness – organisations could use Tuckman and Jensen’s group development model and Belbin’s theory of team roles to review how teams approach collaborative decision-making and develop effective team work. Janis (1971) used real-life examples to construct groupthink theory, explaining poor decision-making, so strategies can be implemented to ensure this does not recur. If organisations understand that groups with members with similar beliefs lead to bias (Forsyth, 2006), care can be taken to ensure a diversity of opinion within the group. Cultural bias – Tuckman and Jensen’s model was developed in the USA, so it may not apply equally to all cultures. Case studies used to develop groupthink theory are based upon decisions made in individualist cultures. The decisionmaking process may be different in collectivist cultures. Some of the cognitive errors suggested in Forsyth’s theory (e.g. attribution error) only apply to individualistic cultures. Issues and debates Application to everyday life Theories of group decision-making have application to everyday life. Once leaders in organisations understand the risks of groupthink and cognitive bias, they can apply these theories to improve group decision-making in their organisation. Individual and situational explanations Groupthink considers the effects of personality, as well as the influence of the situation, making it a more complete theory. NOW TEST YOURSELF 9.25 Ewald is going to give a presentation about the dangers of groupthink. Suggest two factors that he may focus on. [4] 9.26 Belbin (1981) used observation of group dynamics and psychometric testing to develop his nine individual team roles. Evaluate observation as a research method for identifying team roles. [6] 9.27 Joanna has identified heuristics as problematic in her group when it comes to decision-making. Suggest two ways in which she can reduce cognitive errors in the group. [4] 9.28 Forsyth (2006) proposed a theory of cognitive biases as responsible for faulty decision-making. aOutline one of the biases proposed by Forsyth. [2] b Explain the difference between sins of commission and sins of omission, giving an example of each. [4] c Explain one way in which this theory is reductionist.

Two factors affecting social facilitation are: » drive: the increased levels of arousal and internal motivation used to reach a goal – drive theory: Zajonc (Zajonc and Sales, 1966) suggested that in others’ presence, people perform simple familiar tasks better but complex or new tasks worse (due to social inhibition) than if they were alone » evaluation apprehension: anxiety a person feels about being judged by others. Schmitt et al. (1986) randomly assigned 45 undergraduates to one of three working conditions to demonstrate social facilitation and evaluation apprehension. ▼ Table 9.10 The effects of different working conditions on task speed Condition Simple task speed Complex task speed Alone Slowest Fastest In the presence of someone wearing a blindfold and headphones Faster than alone Slower than alone In presence of an evaluating experimenter Fastest Slowest Social loafing Social loafing was first studied by Ringelmann (1913), who observed that people did not reach their individual potential in groups. A group still outperformed an individual, but not at the rate expected. He found that the more people who were pulling on a rope attached to a pressure gauge, the further below their expected pressure they performed. Social impact theory Latané (1981) used this to explain social loafing. In a group, social influence is spread across all members and the bigger the group, the less influence each individual member has. This can lead to social loafing if the person is not being evaluated on their individual performance. SKILLS BUILDER Explain one factor that may lead to social loafing. [2] Clearly identify the factor and explain how it affects the likelihood of social loafing. Social loafing is mainly affected by diffusion of responsibility, which is based on two things: size of the group and anonymity of its members. You could use Latané’s (1981) social impact theory to explain how one of these is related to an increase in social loafing. Relevant research: Earley (1993) Aims: » To investigate the effect of culture on social loafing. » To see whether group and individual efficacy expectations will mediate the effects of group context and collectivism-individualism on performance. Methodology: » Volunteer sample of 165 entry or middle managers: 45 Israelis, 60 Chinese and 60 Americans, aged between 25 and 40. » Experiment, in which participants were randomly assigned to perform tasks under three different conditions: alone; member of a ten-person outgroup; member of a ten-person ingroup. » In the group conditions, participants were not in the physical presence of others but were told they were part of an ingroup/outgroup. – Task: 60 minutes’ office work with a simulated ‘in-basket’ of 40 tasks. – Measured performance, individualism-collectivism and individual and group self-efficacy. Results: » Individualists performed better alone. » Collectivists performed better in ingroups. » Results were partly mediated by self-efficacy levels and expected performance. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 245 245 14/08/23 7:20 PM » Measures of group and individual self-efficacy and anticipated performance were higher for collectivists in ingroups. Conclusions: » Individual and group efficacy increases in collectivists in ingroups. » Individual loafing may occur in collectivists when working alone. » Although collectivism-individualism affects group performance, type of group may be more important. Key study: Claypoole and Szalma (2019) Context: » Research suggests that electronic performance monitoring (EPM) may improve productivity and performance. » However, social facilitation suggests that evaluation apprehension may impair performance of a difficult task that is monitored by another, and Aiello and Svec (1993) found this was also the case with EPM. Aim: to determine whether social facilitation effects could be observed when using EPM on a vigilance task. Research methods and design: » Research method: experiment. » Design: independent samples. Variables: » Independent variable: presence/absence of EPM (webcam and video recorder). » Dependent variables: speed and accuracy of response to 20 random ‘critical signals’ in a 24-minute period. SKILLS BUILDER Outline one strength and one weakness of Earley’s (1993) research into the effect of culture on social loafing. [4] Establish structure by making clear points about Earley’s social loafing research. For a strength, you could discuss how Israelis, Chinese and Americans were used in the sample. Then explain why it is a strength – for instance, ‘Findings are relevant to diverse cultures, making results more generalisable.’ Controlled variables: time period; random allocation of participants to either the experimental or the control condition; identical task for both groups. Sample: volunteer sample of 106 US undergraduates, 65 female/41 male (mean age: 20.57 years). Procedure: » Participants completed a demographics questionnaire. » Experimental condition participants were informed about recording (no actual recording was done). » Participants completed a three-minute practice session followed by a 24-minute vigilance task: – During a computer display of two-digit numbers, a number with only a difference of 0 or +/–1 between each digit, like 45 or 66, would appear. – As soon as it appeared, participants should press the spacebar. – There were 20 of these critical signals. Ethics: voluntary and anonymous participation – course credit was given; informed consent obtained, with some deception, revealed in debriefing. Results: ▼ Table 9.11 Correct detections, overall proportion of false alarms and over median response time in milliseconds (ms) Electronic presence (n = 53) Control (n = 53) Mean SD Mean SD Correct detections 0.6906 0.20 0.6038 0.21 False alarms 0.0059 0.01 0.0201 0.05 Response times 767.34 67.41 802.02 75.67 » EPM condition participants detected significantly more critical signals and had significantly fewer false alarms. » EPM condition participants also had faster median times for each detection. 246 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 246 14/08/23 7:20 PM 9 Organisational Psychology Conclusions: » Social facilitation, including EPM, can be used to improve performance on cognitively demanding but boring vigilance tasks. » Video-based monitoring is an effective monitoring method. ▼ Table 9.12 Methodological issues Strengths Quantitative data – Earley (1993) used quantitative data collection, increasing replicability. Claypoole and Szalma (2019) measured data objectively and statistics were used to draw conclusions regarding social facilitation function of EPM. Reliability – Earley used quantitative methodology (e.g. rating scales); this is less open to interpretation and more reliable than qualitative methods. Claypoole and Szalma used a standardised procedure, which increases the replicability of the research. Usefulness – organisations can use social facilitation theory to predict how people will work in others’ presence and change working practices accordingly. Earley’s findings can be applied in individualist and collectivist cultures, as the participants were from both. Claypoole and Szalma’s research can be used to inform organisations wanting to introduce EPM. Weaknesses Ecological validity – supporting research for theories of individual and group performance is experimental, with low mundane realism. Earley’s participants were just told that they were members of an ingroup or outgroup; there was no interaction with the group. Claypoole and Szalma employed standardised conditions with an unrealistic task. Generalisability – Claypoole and Szalma used participants all from the same USA university. Social facilitation may not be experienced similarly in other populations. Type of data – all of the individual and group performance studies employed quantitative data collection; this does not allow researchers to investigate reasons for the results, making these explanations incomplete. Issues and debates Cultural differences Cultural differences may affect how people react to others’ presence, whether real or electronic. Use of vigilance tasks and webcams varies, so participants would vary depending on familiarity with surveillance. Application to everyday life If EPM can increase performance on vigilance tasks, then organisations can use it to increase workplace productivity. However, volunteer participants agreed willingly to EPM use. There are ethical considerations regarding workplace use. NOW TEST YOURSELF 9.29 Annika complains about group work at school, and says even though the other group members are her friends, they leave her to do most of the task. She accuses them of social loafing and wants to work individually.

The conflict may be: » personal » task-related » due to procedural issues between employees. Workplace conflict has been categorised on four levels. Intra-individual conflict Intra-individual conflict involves choice: » between two positive options » between two negative options » concerning something that has both positive and negative factors, such as being offered a good job in a bad location. Inter-individual conflict Barki and Hartwick (2004) identified three different components of inter-individual conflict: » behavioural (interference) » cognitive (disagreement) » affective (negative emotions). Intra-group conflict Intra-group conflict concerns: » process conflict » relationship conflict » task conflict. Inter-group conflict Ingroup cohesiveness and loyalty may increase at work, but an ‘us’ and ‘them’ mentality may form. When budgets are limited, competition for scarce resources can lead to inter-group conflict. Causes of organisational group conflict Miles (1980) identified a number of factors: » frequency of working together » status inconsistencies » communication problems » individual differences. Other causes of organisational group conflict are: » distrust » scarce resources » organisational changes. 248 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 248 14/08/23 7:20 PM 9 Organisational Psychology Causes of individual/situational interpersonal group conflict ▼ Table 9.13 Causes of interpersonal group conflict Individual Situational Personality differences Competition for scarce resources, like awards or promotions Clashes of values and interests Power and status differences Poor communication Thomas-Kilmann’s (1974) five conflict-handling modes In conflict situations, an individual’s behaviour can be described along two dimensions: assertiveness and cooperativeness. The Thomas-Kilmann model identifies and measures five conflict-handling modes on these two dimensions, using the Thomas-Kilmann conflict mode instrument (TKI), comprising forced-choice answers to pairs of statements linked to each of the five conflict-handling modes. The five conflict-handling modes are: 1 Competing: when a person is assertive and uncooperative, pursuing their own concerns. 2 Accommodating: when a person is unassertive and cooperative, neglecting their own concerns. 3 Avoiding: this person is unassertive and uncooperative, avoiding conflict. 4 Collaborating: when a person is assertive and cooperative, working well with others. 5 Compromising: this person is moderately assertive and cooperative – the true middle-ground solution. Certain people use some conflict-handling modes better than others. Workplace conflict behaviour is therefore a result of both personal predispositions and the situational requirements. Bullying at work Bullying occurs when someone at work is systematically subjected to aggression from others over a period of time, where they cannot defend themselves or escape the situation. Relevant research: Einarsen (1999) Aim: to review and summarise research and literature on the nature and causes of bullying at work. Methodology: review article, using secondary sources. Results: » Nature of bullying: 1 Work-related bullying, such as changing work tasks to make them more difficult. 2 Social isolation. 3 Ridicule – insulting remarks or gossip. 4 Verbal threats – being criticised or humiliated in front of others. 5 Physical violence or threats of violence – this is very rare. » Phases of bullying (escalating from 1 to 4): 1 Aggressive behaviour – subtle aggression begins against one or more people. 2 Bullying – aggression becomes more open. 3 Stigmatisation and victimisation – victim is harassed and alienated, or subjected to offensive remarks and jokes. 4 Trauma – the situation affects the victim’s mental and/or physical health. SKILLS BUILDER Explain one strength of the levels of group conflict explanation for work conflict. [2] Focus on the theory and explanation when planning your answer. You could identify one strength as the ability to explain conflict by referring to both individual and situational factors, thus creating a more complete theory. You could also think about Sherif’s (1962) field experiment evidence of the competition for scarce resources, which provides empirical support. SKILLS BUILDER Suggest two ways that Thomas-Kilmann’s conflict-handling modes could be used in an organisation. [4] Describe the conflicthandling modes first, and then identify two ways that a leader could use this model, including the TKI, if you think this is appropriate in the workplace. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 249 249 14/08/23 7:20 PM » Causes of bullying: 1 The bully: engages in bullying because of competition for status and jobs, feelings of envy and uncertainty. 2 The victim: the personality of the victim provokes aggression in others. 3 The workplace: poor workplace design, poor leadership behaviour, socially exposed victim and low moral standards in the department can lead to increased bullying. Conclusions: future research should focus on victims’ feelings and also address both predatory and dispute-related bullying and take these differences into account. ▼ Table 9.14 Methodological issues Strengths Reliability – Sherif (1962) developed realistic conflict theory, so explanations of group conflict have research support. TKI gathers objective, quantitative data and can be replicated with large numbers of diverse participants, giving high reliability. Einarsen’s (1999) review article methodology used other research studies to summarise the current understanding of bullying, so there is research support. Usefulness – explanations for conflict at work are based on individual and situational factors, so research is helpful for organisations trying to resolve conflict at work. Individuals can use Thomas-Kilmann’s (1974) different styles of conflict resolution to recognise their own strengths in terms of the style they are most comfortable using and to consider other styles that they use less. In Einarsen, awareness of early stages of bullying may mean it can be stopped quickly, meaning less damage to the victim and the organisation’s reputation. Weaknesses Ethics – research needs to minimise harm and maximise benefits to the people being researched and the wider population (Einarsen, 1999). Blaming victims for bullying by pointing to their personality is unethical and puts them at risk of further psychological harm. Cultural differences – group conflict explanations are individualistic, highlighting the importance of status, respect and personality. These may not be important factors in collectivist societies. In the Thomas-Kilmann model, individuals from collectivistic cultures may select avoiding and accommodating styles of conflict-handling more often than those from individualistic cultures. Validity – TKI and Einarsen’s self-report method are both subject to social desirability bias. Issues and debates Individual and situational explanations Einarsen (1999) considers the individual and situational aspects of bullying. He discusses the role of personality in both the victim and the bully, but also the relevance of situational factors in workplace leadership, design and morality. Idiographic versus nomothetic Thomas-Kilmann’s conflict styles take the nomothetic approach, assuming in conflict situations all behaviour can be measured along two dimensions. A more idiographic approach using case studies or interviews may show far more ways of responding to conflict.

Some factors that may affect work performance are: » temperature » noise » light. The Hawthorne effect (Mayo et al.) The term ‘Hawthorne effect’ was first used by the sociologist Landsberger in 1958 when he analysed the results of studies conducted between 1924 and 1932 at the Hawthorne plant of the Western Electric Company in Chicago. Jackson et al. conducted the first field experiments into the effect of lighting at the plant on the productivity levels, in 1924–1927. The first of these is described below. Mayo took over and extended the research from 1928 onwards. STUDY TIP For each piece of ‘relevant research’, try to oppose the points presented in the methodological evaluation tables. For example, if the table gives a strength relating to validity, try to create a validityrelated weakness. Systematically ‘arguing’ in both directions (for and against) will elevate your evaluation, possibly to the top band. Aim: to investigate the effect of lighting on productivity levels. Procedure and results: » The control group’s lighting remained constant. » In the experimental group, lighting levels were decreased: – After one week, production had increased. – In the second week, lighting levels were reduced further and productivity increased again. – Finally, lighting levels were decreased to ‘moonlight’, but productivity did not change. Conclusions: lighting levels were irrelevant; workers knew they were being observed, and so the longer the study went on, the harder they worked. Follow-on studies Mayo et al. conducted a series of experiments changing one part of the work environment, such as rest periods, working day or other physical conditions, for a group of five women. The results provided support for the Hawthorne effect, as whatever was changed, the women worked harder and more efficiently. Kompier (2006) Kompier (2006) suggested five reasons why the Hawthorne effect is a myth ‘that has become a legend’. ▼ Table 9.15 Reasons why the Hawthorne effect is a myth Myth Description Scientific worth The quality of the original case studies is low. Continuous improvement In many of the original studies, researchers ignored periods of time when productivity went down. Social factors being the most important Researchers suggested that productivity improved because of a change in supervision and the extra attention workers received, and not economic interest. However, when incentivised pay was introduced in one study productivity increased, and when it was taken away it dropped. Wholehearted cooperation Researchers suggested that in the first study everyone co-operated with the experiment and with management. However, worker resistance towards management was documented. Neurotic worker Workforce conflict was blamed on the mental health or issues of the worker, blaming the individual rather than the work situation. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 251 251 14/08/23 7:20 PM Impact of the work environment design: open-plan offices An open-plan office is where all employees work on the same floor within the same open space. These spaces are intended to increase collaboration, creativity and productivity through skills and ideas-sharing. James et al. (2021) identified three main factors influencing the recent move to open-plan offices: » type of work – more knowledge-based and complex » technological changes – lightweight laptops and available internet mean work can be done from home, leaving desks unoccupied » cost – cheaper and more space-efficient. There are contradictory findings regarding the impact of open-plan offices on health and social relationships: » Oommen et al. (2008): – positive impacts – more communication, collaboration and flexibility to work in different areas – negative aspects – noisy, loss of concentration, lack of privacy and more stressful. » James et al. (2021): – mainly negatives – affected health and increased stress, lack of privacy, poor lighting, noisy and poor temperature control. Relevant research: Oldham and Brass (1979) Aim: to investigate changes in employees’ reactions to work after moving to an open-plan office. Methodology: » Seven-point rating scale questionnaire measuring job satisfaction, interpersonal satisfaction and internal work motivation. » Completed by American newspaper employees; results compared with two control groups. » Management and employees were questioned informally for qualitative data. » Interviews were held to see whether other changes in the working environment may have occurred simultaneously. SKILLS BUILDER a Describe what psychologists have discovered about the impact of physical work conditions on productivity. [6] b Evaluate what psychologists have discovered about the impact of physical work conditions on productivity, including a discussion on field experiments. [10] In part b, evaluating the methodology of the research studies used in part a, research by Mayo et al. (1924) and Kompier (2006) could cue you to discuss issues such as objectivity and generalisations. Results: » Quantitative findings: – Employees’ internal motivation and satisfaction fell sharply after the move. – There was almost no difference between the experimental group scores and quasi-control group, so decreased motivation and satisfaction was not a result of order effects from completing the questionnaire before and after the move. – A non-equivalent control group showed no difference in their scores before and after the move. » Qualitative findings: – Interviewees described the open-plan office as a ‘fishbowl’, ‘cage’ or ‘warehouse’. – They felt a lack of privacy and inability to concentrate due to noise. Conclusion: » Moving from conventional offices to open-plan office styles can reduce workers’ levels of motivation and satisfaction. » Noise levels and lack of privacy can affect workers’ concentration levels negatively. 252 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 252 14/08/23 7:20 PM 9 Organisational Psychology ▼ Table 9.16 Methodological issues Strengths Weaknesses Reliability – studies have replicated the Hawthorne effect and found those who are observed act differently. Detailed research makes it easy to replicate. Oldham and Brass (1979) used a standardised procedure, with the same structured questionnaire for every participant. This allows easy replication. Generalisability – for Mayo et al. (1920s and 1930s), support came from one set of studies conducted at an electrical plant in Chicago, USA. Oldham and Brass used data from one US company. Particular characteristics may be more prominent meaning open-plan offices did not suit the workers. Cultural factors may have contributed to results, limiting generalisability. Quantitative and qualitative data – Mayo et al. used quantitative and qualitative data from observations, interviews, blood pressure and heart monitoring. Oldham and Brass used seven-point rating scales and informal interviews. The triangulation of methods increases internal validity. Validity – Oldham and Brass’ research is from 1979, lowering the study’s temporal validity. However, James et al. (2021) found a similar negative reaction to open-plan offices nowadays. Issues and debates Determinism versus free will The Hawthorne effect is deterministic, seeing behaviour as determined by social situations and interactions. The researchers concluded that attention and the social presence of others caused the workers’ behaviour change. This ignores the role of free will. Application to everyday life These two studies into physical work conditions have high ecological validity. Both used workers who were going about their normal work. Although Oldham and Brass (1979) used standardised questionnaires, they also had informal conversations with workers, enriching the findings from quantitative data and increasing application to everyday life. NOW TEST YOURSELF 9.37Outline what is meant by determinism, using an example from research into physical work conditions. [2] 9.38 Lori’s workplace manager is considering changing the environment to an open-plan office, saying that it will encourage more collaborative working. Lori and her colleagues are anxious about this and are preparing a response. Suggest two arguments they may use to try and persuade management that this may not be a good idea. Use evidence from research in your answer. [4] 9.39 Explain one strength and one weakness of research investigating the Hawthorne effect. [2] 9.40 A new shop-floor manager has taken over and wants to increase the productivity of the sewing machine operators. First, she wants to find out what conditions might improve productivity and what conditions either have no effect or reduce productivity. a Plan a study using worker questionnaires to find out what conditions the workers need for productivity to improve. Your plan must include details about question format and sampling technique. [10] b Choose a qualitative research method to give you some more information, and explain two strengths of your choice. [4] STUDY TIP Think carefully about the named research method in ‘Plan a study’ questions like 9.40 below. You need to consider the type of data that will be produced and how it can be analysed. For example, questionnaire data is objective and quantitative, but can also make the results reductionist. Adding a qualitative method makes the study more holistic and allows you to understand not just the ‘what’ but the ‘why’. What type of qualitative research method would you choose and how would you conduct the research? Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 253 253 14/08/23 7:20 PM 9.4.2 Temporal conditions of work environments Rotational shift work This is used in manufacturing sectors for continuous production. For example: » Forward rotation shift (phase delay): shift moves from a morning to evening shift, then possibly to a night shift before the cycle begins again. This decreases disruption to the worker’s circadian rhythm. » Backward rotation shift (phase advance): shift moves from a night to evening shift and then to a morning shift. This is known for its negative effect on health. ▼ Table 9.17 Rotation shifts Type Details Issues Rapid rotation: metropolitan Fast forward rotation – four teams x three eight-hour shifts. Each team does two early shifts (6 a.m. to 2 p.m.), two late shifts (2 p.m. to 10 p.m.) and two night shifts (10 p.m. to 6 a.m.) and then has two days off, with a free weekend every eight weeks. Difficult to cover if a worker is absent. Rapid rotation: continental Fast forward rotation – four teams: » Week 1: two early, three late and two night shifts » Week 2: two days off, three early and two late shifts » Week 3: two night shifts, three days off, two early shifts » Week 4: two late, three night shifts, two days off More popular than metropolitan shifts as it allows for every fourth weekend off. Slow rotation Longer intervals between shift changes: day shifts for several weeks and then night shifts for the same number of weeks. More consistency and regular patterns allow workers to plan leisure time. The body adjusts more easily to regular schedules. On-call work patterns To provide 24/7 coverage, workers are on ‘standby’ to respond. This is most common in places such as hospitals or fire service. Two types: 1 Go home after work and at weekends, but can be called back. Need to live near to work and be able to get there very soon after being called. Not allowed to drink alcohol during on-call periods, must always be contactable by phone and possibly be awake at set times. Paid if you are called on. 2 Remain at place of work, but when on call you are able to rest. Paid for whole on-call period. Nicol and Botterill (2004) found that on-call work may increase stress, affect mental health, decrease quality and quantity of sleep, and disrupt family and social life. Flexi-time With flexi-time working, people work the same number of hours weekly but whenever they choose, within employer-set limits. This does not affect total working hours or responsibilities. It requires workers to be disciplined and an ability to track when everyone is working and where. For example: » Arrive: any time between 7 a.m. and 10 a.m. » Lunch: any time between 12 p.m. and 2 p.m. » Leave: any time between 4 p.m. and 6 p.m. » Core working hours: 10 a.m.–12 p.m. and 2 p.m.–4 p.m. Effects on workers: » Flexi-time increases satisfaction and morale. » It reduces stress and fatigue. » Traffic can be avoided. 254 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 254 14/08/23 7:20 PM 9 Organisational Psychology » Employees can choose to be in the office for more hours one day and work shorter hours the next day. » It allows people to work and meet family commitments. Effects of shift work Health Ansiau et al. (2017) investigated the effects of shift work on various factors: » Sleep quality: shift workers and ex-shift workers have poor quantity and quality of sleep. » Quality of life: shift workers have more chronic fatigue than non-shift workers, but there are no differences in social isolation or stress. » Physical health: shift workers are more likely to suffer from obesity, peptic ulcers, gastric problems, failure to control blood sugar levels and cardiovascular disease, especially those who work shifts for more than ten years. » Cognition: shift workers have poorer attention span and episodic memory than non-shift workers. Those who ceased shift work more than five years previously had no differences in cognitive performance. Cardiovascular disease (CVD) Torquati et al. (2018) found the risk of CVD to be 17 per cent higher among shift workers than non-shift workers. The risk of coronary heart disease (CHD) morbidity was 26 per cent higher. Abu Farha and Alefishat (2018) found night shift workers in Jordan had raised risk of CVD and clogged arteries, with frequent and longer night shifts increasing the risk. Reproductive effects Harrington (2001) found night shift work carries a higher risk to women of childbearing age. This is possibly due to menstrual cycle disruptions and increased stress because of conflicts between night shifts and family life. There was an increased risk of miscarriage, low birth weight and premature birth. Accidents Shift work and tiredness may lead to lower performance levels and higher rates of accidents. Ryu et al. (2017) studied factory shift workers in South Korea, finding current shift workers were 2.7 times more likely, and past shift workers were 1.7 times more likely, to have a work-related injury, compared to workers who had never worked shifts. Relevant research: Gold et al. (1992) Aim: to investigate the impact of work schedules on the sleep schedule, sleepiness and accident rates of Massachusetts female nurses. Methodology: » Participants: 878 nurses (mean age: 33.9) and other auxiliary hospital staff. » Questionnaires on their working shifts: – rotator (four day/evening shifts, then four days of nights) – day/evening shifts but no nights – nights – eight shifts a month, no days or evenings – day/evening with occasional nights – nights with occasional days/evenings. » Participants were also asked about: – mixed day and night shifts – sleep–wake times – four hours of sleep (‘anchor sleep’) on working days and days off – sleep quality – alcohol consumption – medication taken – falling asleep at work or when driving to/from work – accidents, errors and ‘near-misses’ in past year. SKILLS BUILDER Research into shift work often takes a nomothetic approach, using questionnaires. Suggest why a more idiographic approach may be preferable when researching the different types of shift work. [4] The characteristics of the different types of data produced by the two approaches can be utilised here. Start by identifying the particular weakness of questionnaires in relation to validity of the findings. Develop your answer by suggesting why this makes a more idiographic approach preferable. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 255 255 14/08/23 7:20 PM Results: ▼ Table 9.18 Comparison of effects of different work schedules Type of shift work Falling asleep at work Odds of falling asleep Odds of accidents/ at least once a week while driving errors Odds of ‘near misses’ Rotational 35% 3.9x 2x 2.5x Night 32.4% 3.6x – – Day/evening 20.7% 1 (base measure) 1 (base measure) 1 (base measure) Conclusion: rotating shift patterns disrupting sleep and circadian rhythms are associated with increased error rates on tasks, due to lapses in attention. ▼ Table 9.19 Methodological issues Strengths Weaknesses Reliability – research into temporal conditions of work environments often uses questionnaires. Gold et al. (1992) used standardised questionnaires – quantitative, objective data from a large sample of nurses that can be analysed statistically, giving easy replicability. Validity – link between shift work and health or accidents is correlational; maybe other factors caused poor health, such as poor diet, family problems and stress. Gold et al.’s self-report measures are subject to social desirability bias. Sleeping while driving or working is not something participants want to admit to, so they may not be honest in their answers. Application to everyday life – if research shows negative effects of shift work, then organisations can adapt working patterns to reduce errors and improve health. Generalisability – Gold et al.’s study may have cultural bias; results may not generalise to other nurses in other cultures, or other USA states. Issues and debates Determinism versus free will Shift work research takes a deterministic approach, suggesting a direct relationship between shift work and poor health/accidents. This excludes other factors, including those over which participants may exercise free will, such as diet or sleep quantity. Quantitative versus qualitative data Gold et al.’s study uses quantitative methods. A more idiographic approach using qualitative methods such as interviews would give insight into the reasons why shift work is problematic. NOW TEST YOURSELF 9.41 Explain two weaknesses of using questionnaires in research into temporal conditions of work environments. 9.42 Abu works as a nurse and has been working a rotating shift pattern for several months.

Important if working in a dark room or moving about. Used for warnings and time-dependent messages. To reduce errors: » Match display to use – for example, digital displays are better than dials for accurate readings. » Group together logically – displays for the same system belong together. » Match display to control – put displays next to their controls. » Use colour – to enhance the display and act as a warning. Controls » Levers, switches, handles, joysticks, pedals, keyboards used to control a machine. To reduce errors: » Group controls logically – in the order they are used and by frequency of use. » Ensure controls can be easily reached and operated. » Protect controls from accidental operation. » Label each control. Reducing accidents at work: token economy A token economy is based upon the principles of operant conditioning where behaviours are rewarded with tokens (secondary reinforcers) that can be exchanged for goods or benefits (primary reinforcers). Relevant research: Fox et al. (1987) Context: every year many people die in mines. Before Fox et al.’s research, the response had been short-term fixes rather than long-term prevention. Aim: to investigate introducing a token economy system in two USA open-cast mines where there had been accidents. Methodology: » Participants: workers in each mine were divided into hazard groups: – Group 1 office jobs were least hazardous. – Group 4 jobs were most hazardous – electricians, scrapers and operators. » Procedure: – Employees earned tokens for working without time lost for injury; not being involved in accidental damage to equipment; behaviour that prevented accidents or injuries. – Tokens were lost for unsafe behaviour. Results: there was a large decrease in days lost through injury as accidents were reduced. The system was used at one mine for 12 years and at the other for 11 years. Conclusion: behavioural programmes are effective at reducing accidents in the long term. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 257 257 14/08/23 7:20 PM SKILLS BUILDER a Describe what psychologists have discovered about the health and safety of work environments. [6] b Evaluate what psychologists have discovered about the health and safety of work environments, including a discussion about operant conditioning. [10] Ensure you choose a study or studies in part a that investigated a system based on operant conditioning (i.e. token economy). When evaluating a study in part b, use GRAVE (generalisations, reliability, applications, validity and ethics) to help you remember different ways of evaluating studies. You do not need to cover all of these concepts though; fewer fully elaborated ideas are a better way to increase your grade. Monitoring accidents at work If accidents are to be prevented, then they need to be monitored and recorded first, so the causes of them can be addressed. There is no universal way of doing this, so accidents may be missed. Key study: Swat (1997) Context: » Two types of monitoring may prevent accidents: active monitoring (preventive checking) and reactive monitoring (post-incident checking). » Poland’s system of documenting accidents was ineffective. Aim: to develop an organisationally useful method of recording risk to find causes of accidents and prevent them. Research methods and design: » Research method: case study and interviews with line managers, safety supervisors and employees. » Design: longitudinal. Sample: » Four industrial plants from different branches (foundry, machinery, meat processing and furniture) in Lodz, Poland. » All of the plants were old, with old equipment. » The plants employed 2964 workers in 1993. Procedure: » Accidents in 1993 were analysed for frequency, severity and causes by: – accident reports – researchers’ investigations of accident protocols – interviews with safety supervisors and line managers. » Minor incidents in 1994 not resulting in death, serious injury or serious damage were analysed, from the meat processing plant, using: – data on first aid cases – interviews with 96 employees. Ethics: » Confidentiality was upheld, though if there were only one of a certain type of factory within that area, it may be easily identified. » Results could be of benefit to the workers. Results: ▼ Table 9.21 Frequency and severity of accidents across four industrial plants 258 Accident Foundry Machinery Meat processing Furniture Average Frequency (per 100 employees) 5.9 2.1 2.8 2.3 2.8 Severity (sick days per accident) 38.8 61.2 41.4 41.2 44.6 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 258 14/08/23 7:20 PM 9 Organisational Psychology ▼ Table 9.22 Frequency rates – types of accidents (per 100 employees) in all plants Fall and slip Manual work Working parts 0.7 1.1 (highest in meat 0.7 (highest in processing: 1.2) foundry: 2.6) Sources of energy Other 0.2 (highest in foundry: 0.9) 0.1 Four essential causes of accidents: » insufficient supervision (highest – 89 per cent) » poor workplace organisation » technical factors (lowest – 11 per cent) » human error. ▼ Table 9.23 Percentage of accidents caused by poor housekeeping/maintenance (slippery floors, faulty staircases, improper tools, incorrect clothing) Foundry Machinery Meat processing Furniture 65 33.3 47.8 37.5 Incidents (meat processing plant, 1994): » There were 254 injuries requiring medical treatment. » There were 23 cases with sick leave days. » Employee interviews suggested total incidents could be as high as 520, meaning many were not reported. Conclusions: » Type and location of accidents and incidents should be recorded. » Poor maintenance/housekeeping should be noted as a key cause. ▼ Table 9.24 Methodological issues Strengths Weaknesses Validity – Swat (1997) used data triangulation and quantitative and qualitative methods. Quantitative organisational data can be compared with interview results to identify differences, increasing the validity of findings. Subjectivity – in Swat (1997), participant and researcher bias may have affected data quality. Employees/line managers may not report accidents for fear of generating problems. Researchers used their own analytical tools, maybe leading to bias in interpretations. Longitudinal design – Fox et al.’s (1987) research ran for many years. Researchers gathered much time-sensitive data and drew valid conclusions about the behavioural programme’s long-term effectiveness. In Swat (1997), researchers investigated trends over a three-year period, allowing more detail to be obtained. Generalisability – in Fox et al., the two mining companies were in the USA, so it may not be representative of all organisations and countries. Case studies have low generalisability, so in Swat (1997), the four plants are not representative of all industries and Poland may not be representative of all countries. Application to everyday life – Research into accidents at work means once you understand the reasons for them, you can develop systems to reduce them. If token economy interventions can decrease workplace accidents, then they are saving money and lives. Validity – in Fox et al., reporting of smaller accidents maybe decreased because of the incentive. The accident level in one mine had reduced before the start of the research. This may have continued without the programme, reducing the validity of the findings. Issues and debates Individual and situational explanations Research into health and safety at work looks at human and system errors, explaining frequency, severity and lack of reporting as a product of both. Swat (1997) used data from accident reports and individual interviews, taking into account both individual and situational explanations. Idiographic versus nomothetic Swat’s study takes a nomothetic approach. However, a more idiographic approach with qualitative data collection would allow investigation of individual reasons behind accidents. Thematic analysis of responses could provide accident prevention information.

Plan a case study that will help him identify the main causes of these. [10] Remember, case studies involve triangulation, so you will need to think of at least two ways in which data could be collected about accidents and incidents at the furniture warehouse. Also, think carefully about how you will ensure these datacollecting methods are valid and reliable (revisit page 80 if you need to). NOW TEST YOURSELF 9.45 Compare questionnaires and interviews as ways of investigating accidents at work. [4] 9.46 Suggest one reason why findings from research into accidents at work may lack validity. [2] 9.47 Explain one strength and one weakness of using operant conditioning to reduce accidents at work. [4] 9.48 Jamal is responsible for health and safety and believes that there is an increasing number of minor accidents happening in his workplace. According to Swat’s (1997) research, suggest what Jamal’s first step should be to investigate this with a view to improving work [2] safety. 9.5 Satisfaction at work 9.5.1 Theories of job satisfaction Two-factor theory: Herzberg et al. (1959) Herzberg et al. (1959) proposed that factors causing job satisfaction and factors causing job dissatisfaction are separate. ▼ Table 9.25 Herzberg et al.’s two-factor theory Motivational factors (satisfiers, intrinsic*) Hygiene factors (dissatisfiers, extrinsic*) Factor For satisfaction Factor Achievement Employees should have a sense of achievement. Company policy Policy should be fair and clear and include flexible working, dress code, breaks, holidays, etc., health care plans for workers and benefits for families. Recognition Employees should be praised and recognised for accomplishments at work. Supervision Supervision should be appropriate, with no bullying. Responsibility Employees should be accountable for their work. Work conditions Conditions should be safe, clean and hygienic. Advancement There should be chances for promotion. Salary Appropriate and reasonable salary should be offered, equal to those at the same level in the same industry. Growth Personal growth should be encouraged. Relationships with peers There should be no conflict or bullying; relationships should be friendly and appropriate. Meaningfulness Work should be interesting and challenging. Job security Employees should feel secure in their job. For satisfaction *See page 230 on Vroom’s expectancy (VIE) theory and page 231 for discussion of extrinsic and intrinsic motivators, which relate closely to intrinsic satisfiers and extrinsic dissatisfiers. Job characteristics theory: Hackman and Oldham (1976) » Job characteristics theory takes a person-fit approach – using personality, behaviours and accomplishments to fit the person to the job. » Beliefs, values and ethnicity also contribute to how someone matches with a job. » Psychological needs must be met. 260 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 260 14/08/23 7:20 PM 9 Organisational Psychology ▼ Table 9.26 Hackman and Oldham’s job characteristics theory Psychological states Matching core characteristics Meaningfulness of the work Skill variety – diversity Task identity – seeing a job through from start to finish Task significance – impact on others’ lives Responsibility of the work Autonomy of decision-making Knowing own effectiveness Feedback regarding own performance Techniques of job design: Belias and Sklikas (2013) Job satisfaction can be increased by job design. » Job rotation: – Workers are moved from one task to another regularly. – This prevents boredom and monotony. – Workers can widen their skills, gaining an understanding of the overall work process. – This does not change responsibility level. » Job enlargement: – Jobs are expanded, allowing workers to take on additional tasks. – This doesn’t mean employees are working harder or repetitively, but using team work to complete the product. – It is a more holistic way of working instead of reductionist. – Job enlargement can bring increased responsibility and job satisfaction. – This is a ‘horizontal’ extension of a job. » Job enrichment: – Workers are given more task responsibility. – This might include redesigning a task or being responsible for a team of workers completing a task. – This is a ‘vertical’ extension of a job. STUDY TIP Create diagrams and flow charts to visually represent the explanations in this section. Use colour to identify concepts in the theories that refer to the individual and those that are relevant to the workplace situation. Look for connections between the theories, such as meaningfulness and enrichment. How might one connect to the other? ▼ Table 9.27 Methodological issues Strengths Weaknesses Reliability – Herzberg’s (1959) theory has support from Maslow’s hierarchy of needs, Vroom’s expectancy theory and theories of motivation at work, increasing its reliability. Even before Belias and Sklikas (2013) developed their theory, Chen and Lu (2012) found job design positively impacted employee motivation and performance. This gives empirical support for the theory. Generalisability – for Hackman and Oldham (1976), the core characteristics of USA workers may not apply in collectivist countries where task diversity and autonomy could be less important. Herzberg interviewed employees in Pittsburgh, USA only. This limits generalisability. In relation to Belias and Sklikas, in some types of work, it is not possible to have job rotation or to expand job role. Also, rotation or expansion of job roles may increase stress in some individuals. Application to everyday life – using Herzberg’s theory, organisations can ensure that workers have both hygiene and motivational factors to improve productivity. Hackman and Oldham’s five job characteristics could be used as a checklist when a job is being created or reviewed, to improve satisfaction and productivity. Ayandele and Nnamseh (2014) found that worker job satisfaction in the African civil service fits this model. Validity – Herzberg’s theory assumes all employees’ needs for recognition and responsibility are identical. However, different people may be motivated by different needs due to their personal circumstances or personality. Issues and debates Reductionism versus holism The job design categories are flexible enough to be applied in a holistic manner. Jobs are not broken down to their constituent parts but are worked on collaboratively or rotated through, so a holistic experience is gained. Cambridge International AS/A Level Psychology Study and Revision Guide Third Edition 9781398344433.indb 261 261 14/08/23 7:20 PM Cultural differences If effective, job design stimulates employees’ motivation and job satisfaction, leading to high levels of employee performance and productivity. However, job rotation, enlargement and enrichment need to be applied in a way that is appropriate to a particular culture; then this model has cross-cultural validity. SKILLS BUILDER Explain one strength of theories of job satisfaction from the holism side of the reductionism versus holism debate. [2] Focus your answer on the strength of a theory that either looks at intrinsic and extrinsic motivators or has flexible job characteristics. (Any of the three theories above would be appropriate.) Think about how the factors are listed, but not reductionist, because both the individual and the situation are given as reasons for flexibility in the approach. The command term ‘explain’ means you should say why the strength identified is a strength. NOW TEST YOURSELF 9.49 aOutline what is meant by idiographic research. [2] b Explain one weakness of theories of job satisfaction from the idiographic side of the debate. [2] 9.50 Describe one difference between motivational factors and hygiene factors, referring to Herzberg et al.’s (1959) two-factor theory. [2] 9.51 Suggest one way in which job design can improve job satisfaction. [2] 9.52 Explain what is meant by situational factors, using research into job satisfaction. [4] 9.5.2 Measuring job satisfaction Rating scales and questionnaires Anonymous self-report employee questionnaires are the usual method for measuring job satisfaction. Job Descriptive Index (JDI): Smith et al. (1969) This is a 72-item questionnaire assessing five dimensions representing job satisfaction. Questions are descriptive and answered using a three-point scale (Yes, No or Undecided [?]). After testing, each word is given a numerical value that reflects how well it describes job satisfaction. The five dimensions are: 1 2 3 4 5 Satisfaction with job in general Satisfaction with level of supervision Salary/pay Satisfaction with co-workers Opportunities for promotion Positive items: ‘Yes’ scores 3, ‘?’ scores 2, ‘No’ scores 1. Negative items: ‘Yes’ scores 1, ‘?’ scores 2, ‘No’ scores 3. The higher the score on the dimension, the more job satisfaction there is. Quality of Working Life (QWL): Walton (1973) Walton argued that no matter the occupation, most employees are dissatisfied at work. He suggested eight dimensions of working life: 1 Adequate and fair compensation – salary 2 Safe and healthy working conditions 3 Opportunity to use and develop human capacity – autonomy and chance to use skills 262 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 262 14/08/23 7:20 PM 9 Organisational Psychology 4 5 6 7 8 Opportunities for growth and security – promotion chances Social integration in the work organisation – sense of belonging Constitution of the work organisation – right to expression and equal treatment Work and total life span – late work or travel away from family Social relevance of work life – social responsibility of organisation QWL evaluation scale: Timossi et al. (2008) Timossi et al. developed a scale to measure each dimension by simplifying the original terms into a standardised questionnaire with a five-point rating scale. Example question (Timossi et al., 2008, p. 6) In regard to a fair and appropriate salary (compensation): 1 How satisfied are you with your salary? (remuneration)? Very dissatisfied Dissatisfied Neither Satisfied Very satisfied 1 2 3 4 5 ▼ Table 9.28 Methodological issues Strengths Weaknesses Quantitative data – JDI and QWL evaluation scales are types of psychometric tests that generate objective quantitative data, increasing the reliability. Validity – JDI and QWL evaluation scales are self-report questionnaires using forced-choice answers. Social desirability or anxiety may lower the validity of the data. Reliability – JDI and QWL evaluation scales are standardised questionnaires, increasing replicability and thus reliability. Usefulness – perceptions of what is fair and adequate treatment at work may vary depending on workers’ personal situations, not just their work situations. This reduces the usefulness of the JDI and QWL scales. SKILLS BUILDER Job satisfaction has been researched using rating scales and questionnaires. Give one difference between rating scales and forced/fixed-choice questions as a way of investigating job satisfaction. [4] This question tests knowledge of additional research methods required for A Level compared with AS Level. Refresh your knowledge of forced/ fixed-choice questions on page 42. The command term ‘give’ means you do not have to describe why rating scales are better or worse than forced/fixedchoice questions; just describe how they differ. You could give an example of a rating scale from the QWL measure (Walton, 1973) and show how the question would have changed if forced/fixed-choice. NOW TEST YOURSELF 9.53 Describe one difference between the Job Descriptive Index (Smith et al., 1969) and the Quality of Working Life measure (Walton, 1973). [2] 9.54 Explain why measures of job satisfaction may be culturally biased. [2] 9.55 Suggest one strength and one weakness of using self-reports to gather data on job satisfaction. [4] 9.56 Workers experience job satisfaction for different reasons. Jennifer would like to know her workers’ main reasons for job satisfaction, so she decides to investigate this. a Plan a study for Jennifer using a questionnaire to find the main reason for job satisfaction among her workers. Your plan must include details about: – question format – sampling technique. [10] b State two reasons for your choice of question format. [2] c Explain one reason for your choice of sampling technique.

Absenteeism and organisational commitment model: Blau and Boal (1987) Different interpretations of organisational commitment and job involvement had previously led to variations in study results. Blau and Boal (1987) operationalised both concepts: » Job involvement – the extent to which an individual identifies with their job. » Organisational commitment: – Behavioural – worker is committed because it costs too much to leave. – Attitudinal – worker identifies with the organisation and wishes to stay. Four types of absenteeism 1 Medical: illness, injury or family demands such as a sick child. Occurs randomly. 2 Career enhancing: allows the employee to further other career goals. Harder to detect, but may peak just before quitting a job or just before an internal transfer. 3 Normative: habitual response to the norms of the organisation regarding absence. ‘Personal day’ or ‘excused absence.’ A pattern will show, and frequency and timing may be predicted. 4 Calculative: employee uses unexcused and excused absence days as permitted by the company. Frequency and total number of days off would normally be greatest for this type of absence. Organisations should ensure absences are carefully recorded to ensure patterns are spotted. The framework of the model Organisational commitment and job involvement were separated into high/low categories and the type of absenteeism was matched to the category. Key study: Giacalone and Rosenfeld (1987) Context: cost of sabotage rising, but very little research done; classified sabotage into different methods with different reasons. Aim: to determine whether individuals who accept more reasons for sabotage will justify sabotage more than those who do not. Research method: survey. Sample: a volunteer sample of 38 labourers (union members) at an electrical factory in north-east USA. Procedure: » Designed a sabotage methods questionnaire and sabotage reasons questionnaire. » Four types of sabotage were asked about: – work slowdowns – destruction of machinery, premises or products – causing chaos – dishonesty. » Answers were collated and grouped into ‘low reason’ (below median) and ‘high reason’ (above median) acceptors. Ethics: » Consent was obtained but participants were not told the true reason for the research (deception). » Answers were anonymous and kept confidential – this could be problematic, as the actions were in some cases criminal. 264 Check your answers at www.hoddereducation.com/cambridgeextras 9781398344433.indb 264 14/08/23 7:20 PM 9 Organisational Psychology Results: ▼ Table 9.29 Mean scores for each of the four methods of sabotage (total taken from the 29 methods in total, split into the four categories) Work slowdown Destruction Causing chaos Dishonesty High acceptors 25 19.8 13.5 15.5 Low acceptors 18.9 13 8.8 12.4 » The high reason acceptors saw all four forms of sabotage as being more justified than did the low reason acceptors, but difference for dishonesty was not significant. Conclusions: » Focusing on recognition and deterrence may help reduce accidents, risk exposure and financial losses. » Those who accept more reasons for sabotage are significantly more likely to justify all types of sabotage except for dishonesty. ▼ Table 9.30 Methodological issues Strengths Weaknesses Reliability – Blau and Boal (1987) operationalised and standardised the concepts, meaning they can be applied objectively and research can be replicated. Giacalone and Rosenfeld (1987) collected quantitative objective data which allowed statistical analyses and comparisons to be drawn, increasing reliability. Generalisation from findings – Blau and Boal’s research was based upon individualist societies; findings may not apply in other cultures with different norms regarding absenteeism. Giacalone and Rosenfeld’s study was conducted with unionised workers in one USA factory; cannot generalise findings to wider population. Validity – in Giacalone and Rosenfeld, participants were given the (socially sensitive) questionnaires by a nonsupervisory colleague, which reduced chances of lying. Usefulness – Giacalone and Rosenfeld’s study was merely an initial investigation; further research into recognition and deterrence would be needed for it to be useful. Issues and debates Application to everyday life If organisations can establish patterns of absenteeism within the workforce, they may be able to address the reasons for it early and save money. Researchers considered that more studies were needed to determine the relationship between perceived justifiability and performing an act of sabotage or willingness to report sabotage. Development of this approach could help encourage reporting sabotage or identifying employees at risk of performing sabotage. Idiographic versus nomothetic Research used a nomothetic approach to workplace sabotage looking for general laws/trends, using structured questionnaires, to apply to all workforces. Idiographic methods (unstructured interviews and focus groups) could provide more insight into sabotage, and why some find it acceptable. SKILLS BUILDER Describe the study by Giacalone and Rosenfeld (1987) on workplace sabotage. [6] You have nine minutes to answer six-mark questions so practise summarising key studies to approximately 200 words. As the command term is ‘describe’, the question is assessing knowledge and understanding only, so strengths and weaknesses are unnecessary.

You will also find suggested marks, as well as commentaries highlighting key strengths and weaknesses in their responses. Preparing for your exams In the chapter on AS Level exam-style questions we looked at how to put together a realistic and effective revision plan. You will need to plan the weeks before your final exams very carefully, especially if you are taking a linear route (or AS retakes), meaning you will sit all four papers. » As before, start by using the revision checklists at the end of each of your A Level option chapters. » Once you have identified any class notes that are missing, you can start creating a plan as you will have a better idea of how long you will need to revise each section. » It might be worth timing yourself again to check whether the length of your optimum study block has changed since you revised for your AS exams (see the chapter on AS Level exam-style questions). » As you did before, create a plan with topics to revise each day, remembering to build in time to test yourself on prior learning and also to set more specific and detailed targets for the next day. » Remember to experiment with different revision strategies to see which ones work best for you. If you find yourself losing focus before the end of a study block, maybe you need to vary the activities you set yourself. For example, make a storyboard instead of flashcards. The question papers The content of the AS Level, including research methodology, is required for the assessment of Paper 3 and Paper 4. Although the core studies are not the direct focus of questions on Paper 3 and Paper 4, you will be expected to show an understanding of the approaches, issues and debates, and psychological research methodology when discussing specialist options. You will have studied two of the four option topics and will be examined on both of these in both A Level papers.
