Biological Psychology In writing this resource I have focused on two questions: What do you need to know? How will your knowledge be assessed? What do you need to know? The simple answer to this is whatever is in these booklets. I have tried to reduce the amount you need to know, without skimping on depth or breadth. Sometimes, it has been hard to make choices – there are so many interesting points to make. I have added a You might like to know section at the bottom of the page. Have a look at it – you could add it to the main answer (perhaps by deleting another point I have made), or just store it in your memory as a little back-up knowledge. How will your knowledge be assessed? One of the important skills for exam success is the ability to anticipate questions. It can be difficult under exam conditions to work out what questions mean, and many marks are lost when students misunderstand or misread the question. A crucial aim of this resource is to provide you with a list of questions and appropriate answers that are most likely to come up. However, these are not exhaustive – that wouldn’t be possible. What kind of questions? The same topic (e.g. illness and the immune system) could be assessed as a 2, 4, 6, 8, 10 or 12 mark question. The marks indicate how much you should write. In the exam, you should be guided by the space provided. Examiner reports make the point that it is quite possible to gain full marks in the space provided. Long questions The exam will include at least one 12 mark question, and may also include an 8 or 10 mark question. These questions are marked for both A01 (50%) and A02 (50%) content. Preparing these answers in advance makes a lot of sense. You will develop the skill of balancing A01 and A02 content – and writing concise answers. The essays provided here are generally about 350 words. Students vary in how much they can write in 18-20 minutes – the range is usually 200-350 words. Don’t be discouraged if you can only manage 200 words, you can improve during revision. And sometimes less is better. When you revise you can reduce the length of the answers, either by deleting or compressing. It is crucial however that you balance your A01 and A02 content. In the exam, use your time wisely and don’t spend too much time on AO1 – always allow time for evaluation. The essays are intended to be suggested ways of answering a question. However there is rarely “the answer” to a question, only “an answer.” If you come across a study, strength or weakness in a textbook that you think is relevant or interesting then feel free to change the essay. Short questions The majority of the short questions are incorporated within the 12 mark essays. Once you learn a 12 mark answer you will usually have answers for 3 or 4 short questions. There is generally more detail given here than you will need for 2, 3 or 4 marks. Reducing the answers during your revision will help your learning. 1 Biological Psychology Research studies You may be required to outline or describe a research study. These questions may: • Ask for an overview of studies. “What have studies shown us about workplace stress?” For this question you would give findings and conclusions of two or three studies, but don’t include procedures. • Ask you to outline one study on a specific topic: “Outline one study into Type A behaviour.” For this question you would describe procedures and findings of one study. • Ask one way a topic has been investigated: “Describe how one study investigated the impact of life events.” For this question you would only describe the procedure (but in enough detail for 4 marks). Research methods The Unit 2 exam will include questions that ask you to demonstrate your knowledge and understanding of research methods – 4 marks in each section (12 marks in all - out of 72 total marks for the Unit 2 exam). In order to prepare yourself for these questions, you should revise the Research Methods section of the Unit 1 exam. Application of knowledge Perhaps the most challenging questions are those that require you to apply your knowledge and understanding of psychology to a novel situation – what I term the “Thinking on the spot!” questions. I have included some examples in the last section. You can’t predict these questions but you can develop your ability to answer them. Some tips are: • Spend time reading your textbook – having more background knowledge increases understanding. • Create one or two “Thinking on the Spot questions!” for yourself on each topic. Practise answering these questions. Use relevant psychological terms and ideas in your answer. It is essential that you explicitly relate your answer to the situation or person described in the question. • Have confidence in yourself – if you know the material, you can apply it as well as anyone else. Many years ago when I started teaching A-level Psychology I read in the standard textbook of that time “To remember is to have organised.” It was an amazing insight for me – and explained where I had gone wrong as a student. The third aim of this resource is to help you organise the information you need. It is a strategy that has worked for the hundreds of students I’ve taught.

(1970) Friedman & Rosenman (1974) Marmot et al. (1997) Stress and the immune system Life changes Personality factors: Type A behaviour Workplace stress 4 Biological Psychology 12 mark question: Outline and evaluate research into stress-related illness and the immune system. DESCRIPTION OF RESEARCH Cohen et al. (1991) • Questionnaires were used to obtain stress index scores for 394 participants. • The participants were then exposed to the common cold virus, and 82% became infected with the virus. • The findings were that the chance of developing a cold (thus, failing to fight off the viral infection) was significantly correlated with the stress index score. Kiecolt-Glaser et al. (1984) • Blood samples were taken from 75 medical students one month before their final exams (low-stress condition) and during the exam period (high-stress condition). • NK (natural killer) cell activity was measured as an indication of immune function. Participants also completed a questionnaire that assessed social isolation and negative life events. • It was found that NK cell activity was significantly reduced in the high stress condition, and the levels were lowest for those participants who reported higher levels of loneliness. Kiecolt-Glaser concluded that the examination stress reduced immune function, and that this was exacerbated by social isolation. EVALUATION 1. The participants were volunteer medical students, which limits generalisation of the results. However, Kiecolt-Glaser et al. have had similar results with other social groups (e.g. carers of Alzheimer patients). 2. Kiecolt-Glaser measured the natural killer cell activity as the index of immune function. However, this is only one component of a highly complex and sophisticated system. 3. The immune system may be affected by a whole range of variables, including a person’s general health, lifestyle and personality. Therefore, it is simplistic to see the relationship between stress and the immune system as a causal one. 4. HOWEVER, it is important to distinguish between short-term and long-term stress. In a major meta-review of 293 studies, Segerstrom & Mills found that acute short-lasting stressors lead to an increase in natural immunity, while chronic (long-lasting) stressors produce a general reduction (down regulation) in immune function (referred to as global immunosuppression). You might like to know The immune system is the body’s main defence against infection by foreign agents (referred to as antigens). It is a complicated network of cells and chemicals that seek out and destroy invading antigens. Antigens include bacteria and viruses. White blood cells (called leucocytes) are key players in our immune system and are produced in the bone marrow. Leucocytes include T and B cells, and natural killer cells. 5 Biological Psychology 12 mark question: Outline and evaluate research into life changes as a source of stress. Holmes and Rahe (1967) Holmes and Rahe devised the social readjustment rating scale (SRRS) to assess the impact of life events. 43 life events are assigned a number of life change units (LCUs), from 100 (death of a spouse) to 11 (minor violations of the law). A person’s stress score is the sum of all the LCUs they have experienced within a period of 12 months. EVALUATION 1. A limitation of the SRRS scale is that it assumes that each life event listed has a similar impact on different people. This is unlikely – e.g. redundancy may be welcomed or dreaded. 2. The scale does not distinguish between negative and positive events. There is evidence that changes perceived as negative produce more stress than changes perceived as positive, and correlate more highly with illness. 3. De Longis criticised the life changes approach on the grounds that most people experience life events fairly infrequently. He argued that the number of daily hassles was a better measure of stress. De Longis et al. (1982) found that hassle scores had a higher correlation with health problems than life events. Rahe et al. (1970): • Over 2,700 American male sailors aboard three navy cruisers were given the SRRS questionnaire to complete just before they left for their tour of duty. • When at sea, health records were kept for each participant, and an illness score was calculated. • Rahe et al. found a weak positive correlation of 0.118 between the LCU scores and the illness scores. • The researchers concluded that experiencing life changes/events increases the likelihood of illness. EVALUATION 1. The study used a correlational analysis and so it is not possible to conclude cause and effect. Other variables might account for the relationship, e.g. people who experience major life events may also drink and smoke more. 2. It is simplistic to see the relationship between life events and illness as a causal one. Studies have found that personality is a mediating variable in the relationship between life changes and illness (e.g. the hardy personality). Kobasa’s research challenges Holmes and Rahe’s basic claim. You might like to know Holmes and Rahe proposed that a score of 150 or more increased the chances of stress-related illness by 30%. A score of over 300 meant an 80% chance of developing a serious illness in the following year. Kobasa studied middle managers who had experienced a high number of life event stressors over the previous three years. (She used the SRRS to select her sample.) She found that those who were rarely ill had hardiness, a personality type that Kobasa claimed made people less vulnerable to stresss. Kobasa’s research challenges Holmes and Rahe’s basic claim. 6 Biological Psychology 12 mark question: Discuss research into daily hassles. KEY IDEAS De Longis criticised the life changes approach on the grounds that most people experience life events fairly infrequently. He argued that the number of daily hassles was a better measure of stress. Daily hassles refer to the stresses of everyday life, for example, concerns about physical appearance or weight, rising prices, misplacing or losing things. Delongis et al. believed that life also contains positive events, known as uplifts that could counteract the negative effects of daily hassles. DeLongis et al. devised a combined hassles (117 items) and uplifts (135 items) scale. EVIDENCE Support for the role of daily hassles comes from De Longis et al. (1982). They gave the Hassles and Uplifts Scale to 100 participants, between the ages of 45 and 64. For a period of a year participants completed monthly measures of hassles and uplifts, life events and health status. The researchers found that hassle scores had a stronger correlation with health problems than life events. (Uplifts were unrelated to health outcomes.) In another study, De Longis et al. (1988) gave 75 married couples both a life events questionnaire and the Hassles and Uplifts Scale. The couples were assessed 20 times over a six months period. The researchers found no relationship between life events and health, but found a significant positive correlation of .59 between hassles and next-day health problems, such as flu, sore throats and headaches. One explanation for the findings is that the stresses produced by daily hassles are cumulative – the minor hassles build up and wear people down. EVALUATION 1. The results of these studies are consistent with findings that suggest there is a distinction between the effects of short-term and long-term stress – chronic stress being more serious. 2. However, the rating of hassles is completed retrospectively. Memories may not be reliable, because recollections are affected by a person’s current state of mind. For example, when feeling depressed, people may over-report negative events and under-report positive ones. 3. The relationship between daily hassles and illness is correlational, and so causality cannot be assumed. There might be a third variable that accounts for the relationship – such as personality. You might like to know Bouteyre et al. 2007) studied the relationship between daily hassles and mental health of 233 students during their first year at a French university. The results showed that 41% of the students suffered from depressive symptoms, and that there was a positive correlation between scores on the hassles scale and the incidence of depressive symptoms. 7 Biological Psychology 12 mark question: Outline and evaluate research into the workplace stress. LACK OF CONTROL There is considerable evidence that people experience stress when they believe they have little or no control over a situation (limited decision latitude). Marmot et al. (1997) Over 7,000 male and female civil servants in London, aged 35-55, completed a questionnaire on workload, job control and social support. All were free from heart problems when the study began. Participants were followed up over five years. Findings: Job control and illness were negatively correlated - the lower the job control, the higher the rate of illness. Low-grade workers reported the lowest job control and had 1.5 times the rate of heart disease as high-grade workers, as well as other stress-related illnesses, e.g. ulcers and cancer. (The study found no link between workload and illness.) WORKLOAD Responsibility (high job demand) is a crucial aspect of workload. There is evidence that a high level of responsibility increases stress-related physiological arousal and stressrelated illness. Johannson et al. (1978) compared 14 ‘finishers’ (high risk) with 10 cleaners (low risk) in a Swedish sawmill. The finishers’ productivity determined the wage rates for the entire factory. The 14 finishers (high risk group) had higher levels of: stress hormones (adrenaline and noradrenaline), stress-related illnesses (e.g. stomach ulcers and migraines) and absenteeism. EVALUATION 1. However, it is difficult to separate the effect of individual differences. In Marmot’s study, workers in lower grades may have some characteristics in common that make them vulnerable to heart disease. Workers in the higher grades may be less prone towards stress because they perceive the work as challenging (e.g. the hardy personality). 2. However, correlations do not show causation. In Marmot’s study we can’t assume that low job control caused stress-related illness. It is possible that the causality is in the other direction – people with poor health are less likely to achieve career success. 3. In many studies it is difficult to separate the effects of different stressors. For example, repetitive work is often low paid and that may be the crucial factor. On the whole, research has supported the view that the most stressful jobs involve high demands and low control (decision latitude). You might like to know There are limitations to the questionnaire method used in Marmot’s study. There may be social desirability effects, e.g. participants may under-report their drinking and smoking. As a result the effects of workplace stress might be exaggerated and effects of life style under-estimated. An application of research into workplace stress is that now many employers take stress in the workplace very seriously. Around one third of employers offer stress counselling to their employees. You may need to know There are a range of sources of workplace stress, including level of noise, temperature, workload, repetitive work. 8 Biological Psychology 12 mark question: Outline and evaluate research into Type A and Type B behaviour. TYPE A BEHAVIOUR Friedman and Rosenman identified three dimensions of Type A behaviour: • time urgency/impatience - always working to deadlines • competitive – achievement oriented • hostile – easily angered According to Friedman and Rosenman, individuals who display Type A behaviour are more vulnerable to CHD (coronary heart disease). Type B behaviour pattern is the opposite of Type A - relaxed, not competitive and not aggressive. EVIDENCE Rosenman et al. (1976): • 3524 California men, aged 39 to 59, were given questionnaires and structured interviews, and identified as Type A, Type X (mixture of Type A and Type B) or Type B. All were free from CHD at the start of the research. • Lifestyle risk factors such as obesity and smoking were controlled for. • They were studied over an 8½ year period. • In that period, 7% of the sample (257) had developed some signs of CHD. Of this group 70% were Type A individuals. • Rosenman et al. concluded that the Type A behaviour pattern increases vulnerability to heart disease EVALUATION 1. However, subsequent research has found that TAB is not a strong predictor of heart disease. One review (Matthews and Haines, 1986) found that only half of the studies on TAB and CHD showed a significant link. 2. It is not clear which aspect of Type A is most strongly associated with CHD. There is some evidence that hostility is the crucial variable and a better predictor of CHD than the broad Type A pattern. Dembroski et al. (1989) found that hostility was more linked to CHD than the overall TAB score. 3. The study is culturally and gender specific and findings should be generalised with caution. • The sample was all male, and research has found that females show smaller increases in the typical physiological measures of stress than males. • The definition of TAB is based on Western cultural concepts. Cohen and Reed (1985) found that Type A behaviour is much less prevalent in Japanese men compared to males in the United States (18.7% compared to 50%). Note: If the question asks about ‘the role of personality’ (that is, a more general question) you could reduce the above and include a brief description (A01) and some evaluative points (A02) about hardiness. (See next page.) You made need to know (for a short question) Several mechanisms have been proposed to explain the link between Type A behaviour and an increased risk of CHD. Compared to Type Bs, Type A individuals respond more quickly to stressful situations. Stress activates the sympathetic branch of the ANS, which leads to a rise in blood pressure, heart rate and constriction of the blood vessels. Chronic elevations of the sympathetic nervous system lead to deterioration of the cardiovascular system. Secondly, the release of stress hormones results in the increase of fatty acids in the bloodstream. Cholesterol particles clump together, leading to clots in the blood and artery walls. This increases the risk of CHD. 9 Biological Psychology 8 mark question: Outline and evaluate research into hardiness. HARDINESS Kobasa identified hardiness as a personality type that makes people less vulnerable to stress. There are three dimensions to hardiness: • control: hardy people have a sense of personal control over the events in their lives • commitment: hardy people have a strong sense of purpose and involvement in the world • challenge: hardy people view stressful situations as challenges to be overcome rather than obstacles EVIDENCE Support for Kobasa comes from her study of American middle managers who had experienced a high number of life events over the previous three years (as measured by Holmes and Rahe’s SRRS). Kobasa found that those who were rarely ill scored high on all three characteristics of the hardy personality. EVALUATION Strengths 1. Research into hardiness can account for studies that have not found a correlation between Type A behaviour and CHD. It may be that some Type A personalities are hardy – e.g. they have high levels of commitment and control. 2. There are real-life applications of research into hardiness. Hardiness training has become more widespread, for example, in the military. Limitations 1. However, although there has been considerable support for the hardy personality, some argue that control might be the crucial dimension and that challenge is the least relevant. 2. Most of the research has used the self-report questionnaires. One limitation of questionnaires is the social desirability effect: people want to present themselves in a favourable light – thus reducing the questionnaire’s reliability. You might like to know Another limitation of the hardy personality: Most of Kobasa’s research was carried out with male, white-collar workers, and this limits generalising the findings. For example, research has shown that there are important gender differences in the response to stress. 10 Biological Psychology 12 mark question: Outline and evaluate one psychological method of stress management. STRESS INOCULATION TRAINING (Meichenbaum): There are three stages 1. Conceptualisation: the client works with the therapist to identify the sources of stress in their lives. The client is encouraged to think more positively about their problems. 2. Skills training and rehearsal: Learning of coping skills (e.g. communication skills, coping self-statements) and relaxation techniques to use in stressful situations. Includes both cognitive and behavioural elements. These skills are rehearsed (sometimes using role play) in the therapeutic setting. 3. Application in the real world: The client is encouraged to apply their new skills and relaxation techniques in the real world. The client and therapist remain in contact and, if necessary, there are further training sessions. EVALUATION Strengths 1. The client develops skills that can be used in the current stressful situation as well as in the future. Therefore its benefits are more long-term than biological therapies. 2. There is research evidence that SIT is effective in a variety of situations, including examination stress and sports performance. Meichenbaum (1977) compared SIT with systematic desensitisation. He found that although both forms of therapy reduced the phobia, SIT helped clients deal with a second, non-treated phobia. 3. SIT avoids the undesirable side effects that are associated with drug therapies, e.g. dizziness or tiredness, and risk of dependency. 4. The skills training (which contain both cognitive and behavioural elements) is aimed at increasing the client’s coping mechanisms – and thus their feelings of control. Limitations HOWEVER... 1. SIT takes time, commitment and money. Therefore, this treatment is not accessible for many social groups, such as the unemployed or low paid. 2. Some argue that SIT is unnecessarily complex, and it is difficult to know which component is mainly responsible for reducing stress. It may be that the range of activities could be reduced. You might like to know... Hardiness training developed from Kobasa’s research on the hardy personality. It also has three stages: 1. Focusing: client is taught to recognise the physiological symptoms associated with stress, such as muscle tension and increased heart rate. 2. Reconstructing stressful situations: how stressful situations could have turned out better or worse 3. Self-improvement: the client is encouraged to take on manageable levels of stress, in order to maintain feeling in control. Other forms of a question on this topic: “Outline and evaluate the use of stress inoculation training as a method of stress management.” (8 marks) 4. 11 Biological Psychology 12 mark question: Outline and evaluate biological methods of stress management. DRUGS 1. Benzodiazepines (BZ’s) are anti-anxiety drugs. They work by reducing activity of the neurotransmitter serotonin and reducing arousal of the central nervous system. They do this by stimulating the activity of GABA, the body’s natural form of anxiety relief. BZ’s are the most common drugs used to treat anxiety, and include Valium and Librium. 2. Beta-blockers do not enter the brain but reduce activity of the sympathetic nervous system in pathways around the body and block receptors on the heart which are stimulated by noradrenaline. Thus, they slow the heart rate and reduce blood pressure. Strengths 1. Effectiveness: drugs are widely available, easy to take and can work very quickly. 2. Drugs can reduce disabling and potentially dangerous symptoms such as acute anxiety and high blood pressure. 3. Drugs don’t require the time and commitment that is necessary with psychological methods, such as stress inoculation training. Limitations: however... 1. Drugs treat the symptoms, not the cause. Symptoms (e.g. anxiety, panic attacks, insomnia) may return if drugs are stopped. 2. People can become psychologically and/or physically dependent on drug treatments and as a result may experience marked withdrawal symptoms, e.g. increased anxiety and tremors, when they stop taking them. 3. There can be undesirable side effects. For example, the side effects of BZ’s can include dizziness, tiredness, and memory impairment. (Beta-blockers do not have major side effects.) BIOFEEDBACK The aim of biofeedback is for the individual to learn how to gain control. The individual is attached to a machine that records and gives feedback regarding involuntary processes such as heart rate, blood pressure or muscle tension. Muscle relaxation and meditation can be employed to reduce physiological reactions. These strategies are then used in everyday situations. Strengths 1. Biofeedback is non-invasive and avoids the disadvantages of drug treatments, such as side effects or physical dependency. 2. There is evidence that biofeedback is effective in the treatment of migraine and for controlling heart rate. Limitation: however... It may be the relaxation rather than biofeedback that produces positive results. If the crucial feature is relaxation, then the cost of the equipment may not be necessary. You might like to know Lau et al. (2002) studied the findings from many studies in a meta-analysis. They found that beta blockers reduced the risk of death by about 20% in patients suffering from heart disease. Other forms of a question on this topic: “Discuss the use of drugs to manage the negative effects of stress.” (10 marks) 12 Biological Psychology Short questions 1. Outline two ways the body responds to stressors. (6) If a stressful situation is identified by the higher centres of the brain, signals are sent to the hypothalamus to activate two systems: • The sympathomedullary pathway When a stressor is experienced the sympathetic branch (SNS) of the autonomic nervous system (ANS) is activated. • The SNS stimulates the adrenal medulla to release the hormones adrenaline and noradrenaline. • The effects of adrenaline include increased heart and breathing rate, and the slowing down of digestion. The pituitary-adrenal system • The hypothalamus stimulates the pituitary gland to secrete ACTH into the blood stream. • ACTH travels to the adrenal cortex (part of the adrenal gland) where it stimulates the release of corticosteroids, for example, cortisol. • Cortisol facilitates the conversion of stored fat and protein into energy and, if sustained over a long period, suppresses the immune system. 2. Explain what is meant by the term immune system. (2) The immune system is the body’s main defence against infection by foreign agents (referred to as antigens). It is a complicated network of cells and chemicals that seek out and destroy invading antigens. Antigens include bacteria and viruses. 3. Outline the impact that stress may have on the immune system. (4) Under stressful conditions the pituitary gland secretes ACTH which acts on the adrenal cortex, causing the release of corticosteroids. One effect is to suppress the immunological responses. If the stress is short lived the effects on the immune system are negligible. However, chronic (long-lasting) stressors produce a general reduction (down regulation) in immune function (referred to as global immunosuppression), leaving the individual vulnerable to stress-related illnesses and infections. (if the question is for 6 marks – add: “This is because high levels and prolonged release of corticosteroids reduce production of T lymphocytes and can lead to shrinkage of the thymus gland.”) 4. Outline one study that has investigated the relationship between stress and the immune system. (4) Kiecolt-Glaser et al. (1984): Blood samples were taken from 75 medical students one month before their final exams (low-stress condition) and during the exam period (high-stress condition). NK (natural killer) cell activity was measured as an indication of immune function. Participants also completed a questionnaire that assessed social isolation and negative life events. Findings: NK cell activity was significantly reduced in the high stress condition, and the levels were lowest for those participants who reported higher levels of loneliness. Kiecolt-Glaser concluded that examination stress reduces immune function, and that this is exacerbated by social isolation. 5. What is the difference between life events and daily hassles? (4) Life events are significant changes in a person’s life that disrupt their normal routines and require adjustment. They include marriage, death of a partner, new job, moving house. Whereas daily hassles refers to the minor stresses of everyday life, for example, concerns about physical appearance or weight, rising prices, misplacing or losing things. 13 Biological Psychology Most people experience life events fairly infrequently, whereas the stress produced by daily hassles are cumulative – the minor hassles build up and wear people down. 6. Outline one study that has investigated the relationship between life events and illness. (4) Rahe et al. (1970): Over 2,700 American male sailors aboard three navy cruisers were given the SRRS questionnaire to complete just before they left for their tour of duty. When at sea, health records were kept for each participant, and an illness score was calculated. Findings: Rahe et al. found a weak positive correlation of 0.118 between the LCU scores and the illness scores. The researchers concluded that experiencing life changes/events increases the likelihood of illness. 7. Explain what research has shown about the stressful impact of life changes. (6) Holmes and Rahe devised the social readjustment rating scale (SRRS) to assess the impact of life events. 43 life events are assigned a number of life change units (LCUs), from 100 (death of a spouse) to 11 (minor violations of the law). Holmes and Rahe proposed that a score of 150 or more increased the chances of stressrelated illness by 30%. A score of over 300 meant an 80% chance of developing a serious illness in the following year. Rahe et al. (1970): Over 2,700 American male sailors aboard three navy cruisers were given the SRRS questionnaire to complete just before they left for their tour of duty. A score was calculated for each participant. When at sea, health records were kept for each participant. Rahe et al. found a weak positive correlation of 0.118 between the LCU scores and the illness scores. 8. Describe what research has shown about the stressful impact of daily hassles. (4 or 6) De Longis et al. (1982) gave the Hassles and Uplifts Scale to 100 participants, between the ages of 45 and 64. The researchers found that hassle scores had a higher correlation with health problems than life events. (Uplifts were unrelated to health outcomes.) In another study, De Longis et al. (1988) gave 75 married couples both a life events questionnaire and the Hassles and Uplifts Scale. The couples were assessed 20 times over a six months period. The researchers found no relationship between life events and health, but found a significant positive correlation of .59 between hassles and next-day health problems, such as flu, sore throats and headaches. 9. Describe two workplace stressors. (3 + 3) Control: There is considerable evidence that people often experience stress when they believe they have little or no control over a situation (limited decision latitude). In his study involving over 7000 civil servants, Marmot found that job control and stress/illness were negatively correlated, the lower the job control, the higher the level of stress/illness. Responsibility: Responsibility (high job demand) is a crucial aspect of workload. There is evidence that a high level of responsibility increases stress-related physiological arousal and stress-related illness. Johansson found that the “finishers” whose work determined the wages of the entire sawmill, had more stress hormones, stress related illnesses and absences than the cleaners. 14 Biological Psychology 10. Outline one study that has investigated workplace stress. (4) Marmot et al. (1997): Over 7,000 male and female civil servants in London (aged 35-55) completed a questionnaire on workload, job control and social support. Participants were followed up over five years. Findings: Job control and illness were negatively correlated, the lower the job control, the higher the rate of illness. Low-grade workers reported the lowest job control and had 1.5 times the rate of heart disease as high-control workers, as well as other stress-related illnesses, e.g. ulcers and cancer. These findings support the view that low control is a workplace stressor. 11. What is meant by Type A behaviour? (3) Friedman and Rosenman identified three dimensions of Type A behaviour: • time urgency/impatience - always working to deadlines • competitive – achievement oriented • hostile – easily angered According to Friedman and Rosenman, individuals who display Type A behaviour are more vulnerable to CHD (coronary heart disease). 12. Explain the difference between Type A and Type B behaviour. (4) Friedman and Rosenman identified three dimensions of Type A behaviour: • time urgency/impatience - always working to deadlines • competitive – achievement oriented • hostile – easily angered By contrast, Type B behaviour pattern is the opposite of Type A - relaxed, not competitive and not aggressive. 13. Explain why having Type A personality makes an individual more likely to suffer the negative effects of stress. (3) Compared to Type Bs, Type A individuals respond more quickly to stressful situations. Stress activates the sympathetic branch of the ANS, which leads to a rise in blood pressure, heart rate and constriction of the blood vessels. Chronic elevations of the sympathetic nervous system lead to deterioration of the cardiovascular system. 14. Outline one study that has investigated Type A behaviour. (4) Rosenman et al. (1976): 3524 California men, aged 39 to 59, were given questionnaires and structured interviews, and identified as Type A, Type X (mixture of Type A and Type B) or Type B. • They were all free from CHD at the start of the research. • Lifestyle risk factors such as obesity and smoking were controlled for. • They were studied over an eight-and-a-half-year period. Findings: At the end of the 8½ years, 7% of the sample (257) had developed some signs of CHD. Of this group 70% were Type A individuals. Rosenman et al. concluded that the Type A behaviour pattern increases vulnerability to heart disease 15. Describe two ways in which personality may modify the effects of stressors. (3 + 3) 1. According to Friedman and Rosenman a person with Type A behaviour pattern is more vulnerable to stress. This is because the behaviour includes time urgency, competitiveness and aggression - characteristics that are likely to trigger physiological responses to stress. 2. According to Kobasa, the hardy personality experiences less stress because she/he feels in control, is committed, and perceives events as challenges rather than obstacles – characteristics that do not trigger physiological responses to stress. 15 Biological Psychology 16. Outline the use of drugs as a method of stress management. (6) Benzodiazepines (BZ’s) are anti-anxiety drugs. They work by reducing activity of the neurotransmitter serotonin and reducing arousal of the central nervous system. They do this by stimulating the activity of GABA, the body’s natural form of anxiety relief. BZ’s are the most common drugs used to treat anxiety, and include Valium and Librium. Beta-blockers do not enter the brain but reduce activity of the sympathetic nervous system in pathways around the body and block receptors on the heart which are stimulated by noradrenaline. Thus, they slow the heart rate and reduce blood pressure. 17. Explain two strengths of the use of drugs as a method of stress management. (2 + 2) 1. They can reduce disabling and potentially dangerous symptoms such as acute anxiety and high blood pressure. 2. Effectiveness: drugs are widely available, easy to take and can work very quickly. 18. Explain two limitations of the use of drugs as a method of stress management. (2 + 2) 1. Drugs treat the symptoms, not the cause. Symptoms (e.g. anxiety, panic attacks, insomnia) may return if drugs are stopped. 2. There can be undesirable side effects. For example, the side effects of BZ’s can include dizziness, dry mouth, and memory impairment. 19. Outline one psychological method of stress management, stress inoculation training. (3) or (6) Stress inoculation training (SIT): There are three stages 1. Conceptualisation: the client works with the therapist to identify the sources of stress in their lives. The client is encouraged to think more positively about their problems. 2. Skills training and rehearsal: Learning of coping skills (e.g. communication skills, coping self-statements) and relaxation techniques to use in stressful situations. Includes both cognitive and behavioural elements. These skills are rehearsed (sometimes using role play) in the therapeutic setting. 3. Application in the real world: The client is encouraged to apply their new skills and relaxation techniques in the real world. The client and therapist remain in contact and, if necessary, there are further training sessions. 20. Explain two strengths of stress inoculation training (SIT). (2 + 2) 1. The client develops skills that can be used in the current stressful situation as well as in the future. Therefore its benefits are more long-term than biological therapies. 2. SIT avoids the undesirable side effects that are associated with drug therapies, e.g. dizziness or tiredness, and risk of dependency. 21. Explain two limitations of stress inoculation training (SIT). (2 + 2) 1. SIT takes time, commitment and money. Therefore this treatment is not accessible for many social groups, e.g. the unemployed or low paid. 2. Some argue that SIT is unnecessarily complex, and that the range of activities and time involved could be reduced. 16 Biological Psychology Questions that require knowledge of research methods 1. How have psychologists investigated the relationship between life events and illness? (3) One way has been through the use of questionnaires. Holmes and Rahe devised the social readjustment rating scale (SRRS) to assess the impact of life events. 43 life events were ranked and assigned a number of life change units (LCUs), from 100 (death of a spouse) to 11 (minor violations of the law). A person’s stress score is the sum of all the LCUs they have experienced within a period of 12 months. 2. Give one strength and one limitation of the above method. (2 + 2) Limitation: Retrospective self-report of life events can be unreliable. People may underestimate or exaggerate the number of life events. Strength: The scale generates quantitative data (the LCU’s are simply added up) - this makes it easy to analyse and compare. 3. Outline a method used by psychologists to assess whether someone shows Type A behaviour. (2) A structured interview method was used to assess Type A behaviour in Rosenman et al. study. The interviewer also noted behavioural signs, e.g. finger tapping, interrupting when the interviewer talked very slowly. 4. What are two strengths of using the interview method for investigating stress? (2 + 2) Qualitative information can be obtained in a semi-structured interview. This allows the participant to freely express themselves. Interviews can consider sensitive issues that might be personal and which a participant might not wish to divulge if more impersonal methods are used. 5. What are two limitations of using the interview method for investigating stress? (2 + 2) Increased risk of investigator effects affecting the responses, for example, conveying approval of certain types of answers to questions about life-style. Participants may be influenced by social desirability. They may want to present a favourable impression, and so may distort their answers, for example, they may underestimate their alcohol consumption. 6. What are two strengths of the questionnaire method for investigating stress? (2 + 2) If the questionnaire provides quantitative data, it is generally easy to analyse and compare. For example, the SRRS - the LCU’s (life change units) are simply added up to produce a score. Questionnaires can be carried out by people who do not require much training, as many questionnaires are self-explanatory (e.g. if questions are fixed choice). 7. What are two limitations of the questionnaire method for investigating stress? (2 + 2) Even if confidentiality is assured, respondents may answer in a socially desirable way (give answers that present them in a positive light). For example, respondents may underestimate their alcohol consumption. This undermines the validity of the data. If questions are ambiguous (unclear) respondents may interpret them differently – which undermines the questionnaire’s validity. 17 Biological Psychology 8. What are two strengths of correlational analysis? (2 + 2) Correlations allow researchers to statistically analyse situations that would be difficult to manipulate experimentally for ethical or practical reasons, e.g. life events or illness. Correlation can establish a relationship between two variables, which could be the basis for further research using the experimental method. 9. What are two limitations of correlational analysis? (2 + 2) Correlation does not identify cause and effect; it only identifies a relationship between two variables (e.g. stress and illness). There may be a third variable (such as lifestyle, alcohol consumption, personality) that accounts for the relationship. Non-linear relationships may be hidden by correlation coefficients (e.g. job demand and stress). For example, stress may occur when there is either too little or too much job demand. Thus, the relationship is curvilinear. 18 Biological Psychology Application of knowledge: Thinking on the spot! For some questions you need to apply your knowledge and understanding of psychology to a novel situation – what I term the “Thinking on the spot!” questions. You can’t predict these questions but you can develop your ability to answer them. Tips for answering: 1. Read the question two times. Write down the areas of knowledge that you could include in the answer, e.g. workplace stress: the importance of control and responsibility. 2. For each item of knowledge, refer to the scenario (the description of a person or situation described in the question). Take two or three aspects of the scenario and relate these to your knowledge. 3. If appropriate give findings from a study that demonstrates what you have written. The most important advice of all: It is essential that you explicitly relate your knowledge to the situation or person described in the question. The following examples might help. I have included some suggestions of relevant psychological knowledge and how you can relate this knowledge to the novel situation described in the question. The answers are longer than you would have time for in the exam – but hopefully give you ideas of how to tackle the questions. LIFE CHANGES, STRESS AND THE IMMUNE SYSTEM Jag lost his job as an electrician at the start of the year and decided to move south where there are better employment prospects and where he could live temporarily with his aunt and uncle. A few months later, he broke up with his girlfriend after a disappointing holiday together. He wants to join a local running group but he has had a series of colds as well as a knee strain that doesn’t seem to get better. Use your knowledge of psychology to explain why Jag is experiencing health problems. (4 or 6) For this question you could include research into life changes and research into the immune system. 1. Identify area of knowledge: Life changes. According to Holmes and Rahe (1967), life changes are a source of stress, and because stress is linked to illness, there will be a relationship between life events and illness. 2. Give examples from the scenario. Jag has experienced several life events over the past several months: redundancy, change of living conditions, holiday, end of a relationship. According to Holmes and Rahe, these experience will be linked to an increase in illness, for example Jag’s colds. 3. Stress and the immune system: Research has shown that stress affects the functioning of the immune system. Jag’s colds and knee injury suggest that his immune system may be affected by the stress. Cohen’s cold study found a positive correlation between colds and stress scores. 19 Biological Psychology WORKPLACE STRESS Ahmed and Calem plan to launch a new magazine aimed at young people. They know its success depends to a large extent on the six people they employ to work for it. They want to create a working environment where the employees don’t experience too much stress and feel motivated. What advice would you give Ahmed and Calem? (Make use of your knowledge of research in this area.) (6) For this question, you could identify two sources of workplace stress: lack of control and responsibility. CONTROL 1. Identify area of knowledge: Workplace stress: A great deal of research has identified a lack of control as a major source of workplace stress. 2. Give examples from the scenario: Ahmed and Calem could increase job control by: • giving workers some say in important aspects of the magazine, for example, monthly columns, ideas for articles • introducing flexi hours so that employees can maintain work/life balance • involving employees in decision making – for example, price of subscription 3. Give findings from relevant research: In his study involving over 7000 civil servants, Marmot found that job control and stress/illness were negatively correlated: the lower the job control, the higher the level of stress/illness. RESPONSIBILITY 1. Identify area of knowledge: There is evidence that a high level of responsibility increases stress-related illness. 2. Give examples from the scenario: Ahmed and Calem should try to share responsibilities between the employees, rather than giving too much responsibility to one person. They could • encourage delegation, for example, from copy editor to assistant • share responsibility for increasing magazine sales • rotate some tasks, e.g. contacting advertisers 3. Give findings from relevant research: Johansson, in his study of Swedish sawmill workers, found that the 14 “finishers” whose work determined the wages of the entire sawmill, had more stress hormones, stress related illnesses and absences than the cleaners. PERSONALITY FACTORS AND STRESS Michael and Natasha are both science teachers in a large comprehensive school. Michael seems to be constantly rushing around, often snapping at students when they get muddled when answering a question in class. He finds it difficult to sleep the night before exam results are released. Natasha works the same hours as Michael, but she is quite positive about teaching and doesn’t moan about the students. Despite a lot of after school marking, she finds time to meet friends and play badminton. She takes the exam results in her stride. With reference to the scenario above, outline the role of personality in the response to stress. (6) For this question you could include Type A behaviour, and the hardy personality. Type A behaviour pattern 1. Identify area of knowledge: Type A individuals respond more quickly to stressful situations. Type B people are the opposite. 2. Give examples from the scenario. Michael is showing Type A behaviour: he has time urgency (always rushing about), he is impatient and easily angered (snapping at students), and competitive (e.g. he worries about exam results). 20 Biological Psychology Natasha is showing Type B behaviour – she is more relaxed and easy going (doesn’t moan about the students, takes the exam results in her stride). 3. Give findings from relevant research: Rosenman and Friedman, in their study of over 3000 Californian men, found that compared to Type Bs, Type A individuals respond more quickly to stressful situations (and that makes them more vulnerable to CHD) . The hardy personality 1. Identify area of knowledge: According to Kobasa, people with hardiness are less likely to experience stress. 2. Give examples from the scenario. Natasha shows signs of the hardy personality. She seems in control of the situation, e.g. has time to see her friends, and is more likely to see teaching as a challenge e.g. she feels positive about her work. 3. Give findings from relevant research: Kobasa found that people with hardiness (commitment, challenge and control) were less likely to experience the negative effects of stress. STRESS MANAGEMENT: STRESS INOCULATION TRAINING Nadine is in her first term at university. Although she was really looking forward to it, she feels stressed nearly all the time, worries about writing essays and is dreading the end of term exam. Her tutor has been very encouraging but she thinks that is how he talks to all the students. Outline what is involved in Stress Inoculation Training and how it could be used to help Nadine. (6) For this question a good strategy would be to briefly outline the three stages of SIT. Include the name of each stage. For each stage, refer to the scenarios. Stress inoculation training (SIT): There are three stages 1. Conceptualisation: the client works with the therapist to identify the sources of stress in their lives. Nadine would talk about her difficulties of writing and her dread of the exam. 2. Skills training and rehearsal: Learning coping skills (e.g. communication skills, coping self-statements) and relaxation techniques. Nadine could rehearse statements like, “I am well prepared the exam.” “I’m really pleased with that essay.” Her therapist may suggest that Nadine does relaxation exercises before each revision session. Nadine and her therapist might use role play to tackle Nadine’s difficulties in accepting praise. (Nadine could play the role of her tutor and give praise to her therapist.) 3. Application in the real world: Nadine will be encouraged to apply her new skills, e.g. arrange to see her tutor and to use relaxation exercises before writing essays. Nadine and therapist will remain in contact and, if necessary, there will be further training sessions, perhaps before the summer exams. 21 Biological Psychology Research Methods What does the graph below tell you about the relationship between stress and the frequency of colds? (2) The graph shows a strong positive correlation between stress scores and number of colds. As the stress scores increase, so do the number of colds. 22 Biological Psychology Revision strategies Hard work pays Over a hundred years ago Ebbinghaus proposed the total time hypothesis. Put simply it means the more time you spend on learning, the more you will learn. Not exactly rocket science, is it? Baddeley, a psychologist who has carried out a lot of research on the subject of memory, refers to this as “you get what you pay for”. There is no substitute for hard work. Index cards – for short questions Make a set of cards for the short questions in each section – that is, one set for Biological, one for Social and one for Individual Differences.. You can either buy index cards from a stationery shop, or cut up cards of different colours. For short questions, write the question on one side, the answer on the other. Simple and old-fashioned, but it works. On the answer side, include images (remember research has found visual imagery is a powerful aid to memory). You may need to reduce the answers given in this Guide. Put a rubber band around the cards – and take them around with you. For the boys, it is a great chat-up line, “Will you test me on my cards?” For you girls, ask a friend, or bribe your brother. Give yourself a reward – “If I go through my cards, I’ll eat a bag of Maltesers.” Put the cards on a table next to your bed – and go through them last thing at night. Outline a biological biological method of stress management.. (6) Cards for 12 mark questions Use four or five different coloured cards for a 12 mark question essay. For example, “Outline and evaluate the cognitive approach to abnormality.” • Use two cards to describe the key ideas of the cognitive approach to abnormality • One card to outline a study that supports the cognitive approach • One card to explain strengths • One card to explain limitations You will need to condense the information (you can use some of the abbreviations and symbols you use for sending texts). Include images and different colour pens. Punch a hole in the left corner of the cards, and hold them together with a treasury tag. This is very effective for organising information. 23 Biological Psychology Method of loci This is an effective way to learn your research studies – makes it easy to retrieve them in the exam. Use a building you know well – either where you live or another place you are familiar with. Make a list of 10 studies that would be useful in the exam for Biological Psychology, e.g. Cohen’s cold study, Marmot et al. workplace study, Friedman and Rosenman’s study of Type A personality. Mentally take a journey around your house, and put a study in each room – at the same time create a unusual or bizarre image for the study, e.g. for Cohen’s cold study, a boy lying on a settee in the living room, holding a tissue to his nose, wearing a tee-shirt with the name ‘Cohen’ written on it. Once you have located the images for the studies, go over them once a day, it only takes a couple of minutes. In the exam, you think of your house....and whiz through the rooms! Record your questions and answers Record your answers on a MP3 player and play it when you go for a walk or before you go to sleep. It may be hard to listen to your own voice – but you will soon get used to it. This is a good strategy for both short and long questions. For short questions, you could leave a gap (30- 60 seconds) in between the question and answer. When you listen to it, try and say the answer before you hear it. Instant positive reinforcement. Last word The best bit of advice I can give you is to make your revision active. Don’t just read through your notes or a textbook. Spend as much time as you can recalling – not fun, but it works. Some students write their answers out (again and again!) – seems tedious, but if it works...Try talking to the mirror – tell a friend or your mum. 24 Social Psychology What you need to know • • • • • • Conformity (majority influence) and explanations of why people conform, including informational social influence and normative social influence Types of conformity, including internalisation and compliance Obedience to authority, including Milgram’s work and explanations of why people obey Explanations of independent behaviour, including locus of control, how people resist pressures to conform and pressures to obey authority How social influence research helps us to understand social change The role of minority influence in social change What you need to do Long questions (8, 10, 12 marks) 1.

Below are suitable studies for the topics listed in the specification. Be familiar with the procedures and findings of each study. Conformity Obedience Asch (1951) Milgram (1963) 2 Social Psychology Terms you may need to know 1. compliance: the person conforms publicly to the views and behaviours expressed by others in the group but continues privately to disagree. Compliance was demonstrated in Asch’s study. 2. conformity (majority influence): occurs when people adopt the behaviour, attitudes or values of the majority. Conformity involves yielding to real or imagined group pressure. Conformity can lead to internalisation or to compliance. 3. deception: misleading research participants about the true purpose of a research study. This can be done by telling participants that the study is concerned with one thing, when it’s really about something else. Participants can also be deceived if certain information is withheld. 4. ethical guidelines: a written code that sets out standards of what is and is not acceptable in psychological research. The BPS publishes guidelines concerning deception, informed consent and protection of participants. 5. ethical issues: considerations that relate to the welfare and well-being of participants in psychological research. Major issues include deception, informed consent and protection of participants from psychological harm. 6. informational social influence: the desire to be right, to have an accurate perception of reality. In an ambiguous situation, we look to others and make a social comparison in order to reduce uncertainty. Can lead to internalisation - a true change of private views to match those of the group. Informational social influence was demonstrated in Sherif’s study. 7. informed consent: an ethical guideline that participants should have full knowledge of the nature and purpose of the research study in order to make an informed decision on whether or not to take part. If participants have been deceived to any degree they can’t give informed consent. 8. internalisation: the individual changes both their public and private view. The change is likely to be permanent. Has been demonstrated in research into both majority and minority influence. 9. locus of control: refers to the sense of control people have over the successes, failures and events in their lives. Locus of control is measured on a scale. Those with a high internal locus of control largely feel that their actions are their own choice and responsibility. Those with a high external locus of control see their actions as resulting largely from factors outside their control such as luck or fate. 10. minority influence: a form of social influence where people reject the established norm of the majority of group members and move to the position of the minority. Minority influence was demonstrated in Moscovici’s study in which participants moved to the position of the minority in 8.42% of the trials. 11. normative social influence: the desire to be liked, to be accepted, and to avoid rejection. Can lead to compliance - publicly conforming, but privately maintaining own views. Normative social influence was demonstrated in Asch’s study. 12. protection of participants: an ethical requirement that research participants should be protected during an investigation. The participant’s psychological wellbeing, health, and dignity must not be threatened in any way, for example, by humiliation or embarrassment. 3 Social Psychology 12 mark question: Outline and evaluate explanations of conformity. THE DUAL-PROCESS DEPENDENCY MODEL According to this model, there are two reasons for conformity: Normative social influence: the desire to be liked, to be accepted, and to avoid rejection. Can lead to compliance - publicly conforming, but privately maintaining own views Informational social influence: the desire to be right, to have an accurate perception of reality. In an ambiguous situation, we look to others and make a social comparison in order to reduce uncertainty. Can lead to internalisation - a true change of private views to match those of the group. EVIDENCE Normative social influence was supported by Asch’s study (1951). Asch found that participants agreed with the incorrect majority (confederates) on 37% of the trials. When questioned by Asch after the study, some participants said they knew the answers were wrong, but conformed because they feared disapproval. Support for informational social influence comes from Sherif’s study in which participants were asked how far a light appeared to be moving (the autokinetic effect). Sherif found that there were wide variations between individuals when asked to form a judgement in isolation, but when in groups answers converged and a group norm emerged. EVALUATION 1. However, the dual-process dependency model has been criticised because it does not acknowledge the importance of a sense of belonging to a group. 2. A further weakness is the model’s view that NSI and ISI are separate explanations. Some argue that the two work together and influence conformity – that is, we may look to others for information, but fear rejection at the same time. SOCIAL IDENTITY THEORY People define themselves by the social groups they belong to. These groups serve as reference groups for us and have powerful influence on our behaviour. Groups provide norms that are internalised by the group members. People conform to group norms because they identify with the group. EVIDENCE Support for social identity comes from research that has found conformity increases in groups in which people feel they belong. In Abrams et al. (1990) version of Asch’s line study, the level of conformity was higher than Asch’s original study when participants believed the group contained fellow psychology students. Note: Another way to answer this question is to give informational and normative social influences as two different explanations, and leave out social identity theory. If you do, add the two evaluative points described below. You might like to know Perrin and Spencer (1981) argued that Asch’s classic studies reflected the social and historical aspect of 1950’s America where pressures to conform were very high – which limits the ecological validity. In their study carried out in 1981, Perrin and Spencer found no evidence of conformity. However, in Asch’s study, 13 participants (26%) never conformed – a finding that demonstrates important individual differences in conformity. 4 Social Psychology 12 mark question: Outline and evaluate Milgram’s studies of obedience. DESCRIPTION OF RESEARCH Procedure 1. Milgram obtained 40 male volunteers via a newspaper advertisement to take part in a learning experiment at Yale University. 2. The participant was always assigned the role of “teacher”. Mr Wallace, a confederate, played the role of “learner”. 3. The participant was instructed to punish the learner (who was in another room) each time he gave a wrong answer by administering an electric shock that increased in intensity by 15 volt increments, up to a maximum of 450 volts. 4. The participant did not know until the end of the experiment that the shocks were not real, and the screams were pre-recorded. Findings 1. All participants continued to at least 300 volts. 2. 65% of participants (26 out of 40) went up to the maximum 450 volts. 3. Most participants complained and said they didn’t want to continue. 4. Many became very anxious and distressed (trembling, shaking etc.). 5. Only five participants (12%) stopped at 300 volts. EVALUATION 1. Experimental validity (internal validity) Orne and Holland (1968) claimed that Milgram’s study lacked experimental validity. Participants did not believe they were delivering shocks, and were thus responding to demand characteristics. However, Milgram rejected these claims, arguing that only 2.4% did not believe the shocks were real. Participants interviewed after the experiment gave every indication that their distress was real. 2. Ecological validity (mundane realism) Orne and Holland also claimed the study lacked mundane realism – the research setting was not like real life. The experimenter/participant relationship is unique, unlike relationships in the outside world. However, Milgram argued that the same processes are at work in a lab setting as in a naturally occurring setting: the participants view the experimenter as responsible. When Milgram transferred his study to a rundown office building the obedience rate was 47% (lower than at Yale but still fairly high), demonstrating that although the lab setting played a part, it was not the crucial factor. This variation supports Milgram’s arguments that the study had ecological validity. Note: ecological validity: the degree to which findings from a study can be generalised beyond the particular setting in which they are collected (also referred to as mundane realism). experimental validity: the belief of participants in an experiment that the experimental situation is real. Any threat to experimental validity reduces the extent to which findings can be generalised to real life settings (also referred to as experimental realism). 5 Social Psychology You might like to know Variations to Milgram’s original study: Obedience rates decrease Obedience rates increase Venue moved to seedy offices in nearby town 47.5% Teacher and learner in the same room 40% Teacher paired with an assistant confederate who threw the switches Teacher instructed to force learner’s hand down on to plate to receive shock 30% Experimenter gave instructions by telephone 20% “Two peers rebel”: the teacher was paired with two other teachers (confederates) who refuse to obey 10% 6 92.5% Social Psychology 12 mark question: Discuss ethical issues in Milgram’s research. Ethical issues in Milgram’s research include deception, protection of participants and right to withdraw. However, note that these guidelines were not in place when Milgram carried out his research. So don’t write that Milgram broke ethical guidelines. DECEPTION Milgram deceived participants about the aim of the study: he told them the study was about the effect of punishment on learning. The participants did not know • Mr Wallace was a confederate • the screams were pre-recorded • the shocks were not real Thus participants were unable to give informed consent. However, after the study, Milgram sent out a questionnaire to over 1,000 people who had taken part in his studies. 92% of his participants responded. Of these: • 84% of the participants said they were glad to have taken part • 80% said they felt more experiments of this kind should be carried out • 1.3% said they were sorry to have taken part According to Milgram: “The central moral justification for allowing a procedure of the sort used in my experiment is that it is judged acceptable by those who have taken part…the participant, rather than the external critic, must be the ultimate source of judgement.” (Milgram, 1974)* PROTECTION OF PARTICPANTS Baumrind (1964) criticised Milgram for not protecting his participants. Many experienced considerable distress during the experiment - stuttering, sweating and digging their fingernails into their own flesh. One participant experienced a seizure. However, • • • Milgram attempted to gain presumptive consent before the study by asking other psychologists to predict the findings. Most suggested that only one or two in a hundred would go to 450v. Milgram argued that his participants were provided with a thorough debriefing at the end of the experiment, when he attempted to make all participants feel all right about their actions. The participants were visited and interviewed by a psychiatrist one year after the experiment, and there was no evidence of psychological harm. RIGHT TO WITHDRAW Although Milgram gave his participants the right to withdraw at the start of the experiment, he made it extremely difficult for them to do so throughout the study. When they showed reluctance to continue they were given prods by the researcher, e.g. “The experiment requires that you continue.” However, Milgram claimed that participants knew they were free to leave, as demonstrated by the fact that some people (35%) did leave. *Note: this quote is for you – I doubt you would have time to use it in the exam. Maybe you could remember part of it. You might like to think about The central dilemma in research is that the ethical responsibility to society comes into conflict with the more specific responsibility to each individual research participant. According to Aronson (1999), a cost-benefit analysis is appropriate: the weighing up of how much good will result from the study (in terms of knowledge) compared to how much distress the research participant experiences. 7 Social Psychology 12 mark question: Outline and evaluate two explanations of why people obey. PERCEPTION OF AUTHORITY AS LEGITIMATE • Most societies are ordered in a hierarchical way, with some members having legitimate social power. • This power is held by authority figures whose role is defined by society. • It is extremely difficult to deviate from social roles which are learned throughout childhood. EVIDENCE/EVALUATION 1. This explanation is supported by a variation of Milgram’s research. When the setting was changed from Yale University to a run-down office block, obedience rates dropped to 47%, presumably because the experimenter’s legitimate authority was diminished. 2. Further support comes from Bickman’s (1974) field experiment in New York. 92% of pedestrians obeyed an order to give a stranger money for a parking meter when the researcher was dressed as a guard, compared to only 49% when he was dressed in civilian clothing. THE AGENCY THEORY 1. According to Milgram, people operate on two levels: • as autonomous individuals - aware of consequences • the agentic level - seeing themselves as agents of others 2. The obedient person sees him/herself as an agent of external authority - the agentic state. As a result, legitimate authority replaces the individual’s own selfregulation and is seen as responsible 3. The agency theory was demonstrated in Milgram’s study. Many of the participants had reservations about continuing to administer shocks and required reassurance that they were not personally responsible for the shocks. EVIDENCE/EVALUATION 1. Support for the agency theory comes from Hofling’s field study that found that 21 out of 22 nurses were prepared to break hospital rules and administer a dangerous dose of a drug when ordered to do so by an unknown doctor. However, other studies have challenged these findings. 2. Further support comes from Milgram. In one variation the participant was paired with another teacher (confederate) and had only to read out the word-pairs (the shocks were delivered by the confederate). In this variation, obedience rose to 92% - presumably because the participant was able to shift responsibility (the agentic shift). You might like to know Other explanations of why people obey: • Gradual commitment (known as the ‘foot in the door’ technique.): This was demonstrated in Milgram’s obedience studies. The participants became locked into obedience in small stages (increasing the shocks in 15V increments) – each action was a small step beyond the previous action. The deeper you are in, the harder it is to escape. • Buffers: aspects of the situation that protect people from seeing the consequences of their actions. For example, in Milgram’s original study, the teacher and learner were in different rooms. • Authoritarian personality: Milgram found that participants who were authoritarian tended to give stronger shocks than those who were less authoritarian. 8 Social Psychology 8 mark question: Explanations of independent behaviour: Discuss research into locus of control. LOCUS OF CONTROL People with high internal LOC feel they are in control of the events in their lives and are responsible for their actions. People with high external locus of control feel the events in their lives are controlled by external forces. Evidence generally shows that those with high internal locus of control are more likely to be independent than those with high external LOC. This may be because they have more self-confidence to resist social influence. They are also more likely to be leaders. Those with high external LOC have lower self-esteem and need more social approval, making independent behaviour less likely to occur. • Elms and Milgram found that disobedient participants in Milgram’s studies had scores demonstrating high internal LOC. • Avtgis (1998) carried out a meta-analysis of studies and found that those who scored higher on external LOC were more likely to conform than those with high internal LOC. The average correlation was 0.37. EVALUATION OF RESEARCH 1. HOWEVER, research into the relationship into locus of control and conformity is not consistent: LOC is not always related to conformity. One study found that participants who conformed the most in an Asch type task were less assertive, but did not score differently on the LOC scale. 2. Measuring locus of control is difficult. Questionnaires (e.g. Rotter, 1966) have the limitation of social desirability effects – answering in a way that makes the respondent look good, which would undermine the questionnaire’s reliability and validity. For example, the person may not really agree with the statement, “Becoming a success is a matter of hard work, luck has little or nothing to do with it”, but ticks it anyway. You might like to know Research has found that self-esteem has also been associated with independent behaviour. However, individuals high in self-esteem also tend to have high internal locus of control (Sterbin & Rakow, 1996). Hence it is difficult to know whether the crucial factor is self-esteem or internal locus of control. 9 Social Psychology 12 mark question: Explanations of independent behaviour: Discuss how people resist pressures to conform. A question on independent behaviour could be general, in which case you could include both conformity and obedience and would need to reduce the essay below. Or it could specify either conformity or obedience. SITUATIONAL FACTORS: DISSENT Research has shown that conformity will be significantly reduced if the majority is not seen to be unanimous in its opinion. As soon as the unanimity of the majority group is weakened, non-conformity is more likely to be seen as an appropriate response. The dissenter represents a form of social support and liberates others from the need to conform to the majority. Support for the role of dissent comes from a variation in Asch’s study. The presence of a dissenter was a crucial variable for increasing independent behaviour. When one of the confederates agreed with the naive participant, conformity dropped to 5.5%. Even if the dissenter (another confederate) gives a different wrong answer, conformity decreased to 12%. Asch concluded that it is the unanimity of the group that is crucial. INDIVIDUAL DIFFERENCES: LOCUS OF CONTROL People with high internal LOC feel they are in control of the events in their lives and are responsible for their actions. People with high external locus of control feel the events in their lives are controlled by external forces. Evidence generally shows that those with high internal locus of control are less likely to conform than those with high external LOC. This may be because they have more self-confidence to resist social influence. They are also more likely to be leaders. Those with high external LOC have lower self-esteem and need more social approval, making independent behaviour less likely to occur. Support for the role of LOC comes from Avtgis (1998) who carried out a metaanalysis of studies and found that those who scored higher on external LOC were more likely to conform than those with a low score. The average correlation between LOC and conformity was 0.37. EVALUATION HOWEVER, research into the relationship between locus of control and conformity is not consistent: LOC is not always related to conformity. One study found that participants who conformed the most in an Asch type task were less assertive, but did not score differently on the LOC scale. You might like to know Another situational variable: Reactance is when we change our views to a position opposite to that expected. It is more likely to occur if we think a view is being forced on us. This may make us ‘react’ against it, changing our viewpoint away from the majority. In Asch’s original study, conformity occurred in 37% of the trials. In nearly two thirds of the trials, the participants stuck to their original opinion despite being faced by an overwhelming majority expressing a totally different view. Thus, one interpretation of Asch’s study is that the majority of people do not conform. 10 Social Psychology 12 mark question: Explanations of independent behaviour: Discuss how people resist pressures to obey authority. A question on independent behaviour could be general, in which case you could include both conformity and obedience and would need to reduce the essay below. Or it could specify either conformity or obedience. Milgram’s variations on his original study suggest that anything that detracts from seeing the person giving orders as a legitimate authority, and/or increases our feeling of personal responsibility (that is decreases the agentic state) will make obedience less likely to occur. FEELING RESPONSIBLE FOR ACTIONS According to Milgram’s agency theory, people are more likely to resist authority when they feel autonomous, that is, when they feel responsible for the consequences of their behaviour. EVIDENCE Milgram’s agency is supported by findings from two variations of his study of obedience: 1. When the learner was in the same room as the teacher, the obedience level dropped to 40% - the teacher could see the consequences of the shocks. 2. When the teacher held the learner’s hand down obedience levels decreased to 30% – presumably because the participant felt more responsible. DISOBEDIENT MODELS There is evidence that when a person is provided with role models for resisting authority, they are more likely to disobey. Seeing others people disobey shows that it’s possible to resist pressures to obey, as well as how to disobey. EVIDENCE This explanation is supported by one of Milgram’s variations: the participant was paired with two other teachers (confederates). The two confederates refused to continue after 150v and 210v. In this variation obedience decreased to 10%. THE IMPORTANCE OF A GROUP A group of people who share a similar view can be used against an authority figure to present an alternative consensus of the correct way to behave. This can be seen in strikes, demonstrations and revolutions. Groups provide greater opportunity for dissent to be expressed as well as social support to justify and implement rebellion. EVIDENCE 1. The importance of the group is supported by Gamson et al. (1982), in which the ‘co-ordinator’ (the researcher) asked participants to go against their own views and sign statements that could be used in court proceedings. The participants had ample time for group discussion to resist authority – 32 out of the 33 in the group rebelled in some way. 2. Rank and Jacobsen (1997) found that only 11% of nurses obeyed a doctor’s instructions to give too high a dose of medication to patients when they had the chance to talk to other nurses beforehand. 11 Social Psychology 12 mark question: Discuss how social influence research helps us to understand social change. MINORITY INFLUENCE Minority influence is important for the introduction and acceptance of new ideas and ways of doing things. A minority can challenge the beliefs and values of the majority, causing them to re-think their beliefs. Minority influence is most effective when it shows both consistency and flexibility. For Moscovici, consistency is crucial because it • presents the minority as committed and confident • disrupts the comfortable feeling of the majority viewpoint and produces a degree of uncertainty Support for the role of consistency in minority influence comes from Moscovici. A group of six people were asked to name the colour of slides that were various shades of blue. Two of the six were confederates. Moscovici found that the naive participants named the slides as ‘green’ in 8.42% of the trials when two confederates answered green on every trial. However, Nemeth (1987) argued that flexibility is more crucial than consistency. He found that when the consistent minority (a confederate) moved some way towards the majority position, he had more influence than when he remained consistent and refused to change his position. SNOWBALL EFFECT Once a few members of the majority start to move towards the minority position then the influence of the minority begins to gather momentum. Clark’s (1998) mock jury study of the film 12 Angry Men showed how people begin to change their minds when they see others defecting and adopting the minority viewpoint. THE ROLE OF DISOBEDIENT MODELS Independent behaviour can also bring about social change. The role of disobedient models has been shown in many movements for social change, including the Civil Rights movement in the US and the Anti-Apartheid movement in Africa. There is evidence that when a person is provided with role models for resisting authority, they are more likely to disobey. Seeing other people disobey shows that it’s possible to disobey, as well as how to disobey. Support for the role of disobedient models comes from one of Milgram’s variations: the participant was paired with two other teachers (confederates). The two confederates refused to continue after 150v and 210v. In this variation obedience decreased to 10%. You might like to know Hogg and Vaughn (1998) claimed that minorities are more likely to be influential if they are seen to be acting from principle (not out of self-interest) and have made sacrifices in order to maintain their position. Social cryptoamnesia: Minority ideas are often rejected because people find it difficult to identify with those who put them forward, who might be perceived as a negative out group. According to the process of social cryptoamnesia people tend to forget those who put forward new ideas but nevertheless remember the ideas themselves. This allows people to take on the minority views without identifying with the minority. 12 Social Psychology 8 or 12 mark question: Discuss the role of minority influence in social change.

EVALUATION OF MINORITY INFLUENCE RESEARCH Limitations 1. The participants in lab experiments are usually students. They are very different from minority groups in the wider society who seek to change majority opinion and have something at stake. This limits the extent to which findings can be generalised to real-life settings. 3. It is simplistic to assume that minority influence is demonstrated openly and immediately. The influence exerted by a minority may be hidden, invisible to simplistic behavioural measures, but nonetheless be present. Note: For an 8 mark question on the role of minority influence in social change, it should be enough to write what you have included on minority change for the previous 12 mark question: Discuss how social influence research helps us to understand social change. If the question is for 12 marks you could add what is written here – a description of social cryptoamnesia and two further evaluative points. You might like to know: Hogg and Vaughn (1998) claimed that minorities are more likely to be influential if they are seen to be acting from principle (not out of self-interest) and have made sacrifices in order to maintain their position. 13 Social Psychology HELPFUL NOTES: ETHICS HOW DO PSYCHOLOGISTS DEAL WITH ETHICAL ISSUES? 1. Ethical guidelines The BPS (British Psychological Society) has published a set of written guidelines on how psychologists should conduct their research. Guidelines cover a range of ethical issues, including deception, informed consent, protection of participants, right to withdraw and confidentiality. 2. Ethical committees Ethical committees scrutinise research proposals in order to judge whether ethical issues have been adequately dealt with, and whether the value of the research justifies any cost to the participant. They either approve or reject the proposed research. There are ethical committees at most institutions (psychology departments in universities, hospitals) where research takes place. 3. Presumptive consent One way of dealing with the issue of consent is to obtain the views from a number of people regarding the acceptability of a proposed research procedure or study. These people would not participate in the study, but their views could be taken as evidence of how people in general would respond to participating in the research study. 14 Social Psychology KEY STUDIES: CONFORMITY SHERIF (1935) PROCEDURE 1. Sherif used the autokinetic effect: This is an optical illusion in which a stationary spot of light in a darkened room appears to move. 2. Sherif asked individual participants to judge how far the light appeared to move in a number of trials. 3. Later, the participants worked in groups of three people, giving their responses out loud. FINDINGS 1. Each individual’s estimates varied widely at first, but then became relatively stable. But between participants there was considerable variation. 2. When the same participants then worked in groups of three, their judgements converged until a group norm emerged. CONCLUSIONS One conclusion to be drawn is that when faced with an ambiguous situation, the participants looked to others in the group for guidance, that is, they experienced informational social influence. ASCH (1951) PROCEDURE 1. Asch devised a simple perceptual task that involved participants deciding which of three comparison lines of different lengths matched a standard line. The answer was always obvious. 2. Seven to nine confederates were seated around a table. The naïve participant was always the last or last but one to say the answer out loud. 3. The confederates were told to give unanimous wrong answers in 12 critical trials when Asch gave a secret signal. (There were 18 trials in all.) 4. 50 naïve male students were tested. FINDINGS 1. There was a mean conformity rate of 37%, 2. There were also wide individual differences: • 13 people (26 %) never conformed • 74% conformed at least once CONCLUSIONS Given that the task was unambiguous the findings clearly show the impact of a unanimous group on the behaviour of an individual. The reasons given to explain wrong answers after debriefing show that many of the naive participants felt under pressure to conform to the answers given by the majority. They publicly complied even though they privately believed the answers were wrong. 15 Social Psychology Short questions 1. What is meant by the term conformity (majority influence)? (2) Occurs when people adopt the behaviour, attitudes or values of the majority. Conformity involves yielding to real or imagined group pressure. Conformity can lead to internalisation or to compliance. 2. Outline two explanations of why people conform. (3 + 3) informational social influence: the desire to be right, to have an accurate perception of reality. In an ambiguous situation, we look to others and make a social comparison in order to reduce uncertainty. Can lead to internalisation - a true change of private views to match those of the group. normative social influence: the desire to be liked, to be accepted, and to avoid rejection. Can lead to compliance - publicly conforming, but privately maintaining own views. Normative social influence was demonstrated in Asch’s study. 3. Explain the difference between normative and informational social influence. (4) Differences between normative and information social influence include: Need to be accepted by others (normative), whereas informational is the need to be right/have an accurate perception of reality (informational). Normative social influence is associated with compliance, whereas informational social influence is associated with internalisation. 4. What is meant by the term compliance? (2) The person conforms publicly to the views and behaviours expressed by others in the group but continues privately to disagree. Compliance was demonstrated in Asch’s study. 5. What is meant by the term internalisation? (2) The individual changes both their public and private view. The change is likely to be permanent. Internalisation has been demonstrated in research into both majority and minority influence. 6. Describe two types of conformity. (2 + 2) Compliance: the person conforms publicly to the views and behaviours expressed by others in the group but continues privately to disagree. Compliance was demonstrated in Asch’s study. internalisation: the individual changes both their public and private view. The change is likely to be permanent. 7. Outline one study that has investigated conformity. (4) Procedure Asch devised a simple perceptual task that involved participants deciding which of three comparison lines of different lengths matched a standard line. The answer was always obvious. Seven to nine confederates were seated around a table. The naïve participant was always the last or last but one to say the answer out loud. The confederates were told to give unanimous wrong answers on 12 critical trials when Asch gave a secret signal. (There were 18 trials in all.) 50 naïve male students were tested. Findings There was a mean conformity rate of 36%, There were also wide individual differences: 13 people (26 %) never conformed 74% conformed at least once 16 Social Psychology 8. Outline two explanations of why people obey. (3 + 3) PERCEPTION OF AUTHORITY AS LEGITIMATE Most societies are ordered in a hierarchical way, with some members having legitimate social power. This power is held by authority figures whose role is defined by society. It is extremely difficult to deviate from social roles which are learned throughout childhood. AGENCY THEORY According to Milgram, people operate on two levels • as autonomous individuals - aware of consequences • the agentic level - seeing themselves as agents of others The obedient person sees him/herself as an agent of external authority - the agentic state. As a result, legitimate authority replaces the individual’s own selfregulation. 9. Outline one study that has investigated obedience. (4) Procedure Milgram obtained 40 male volunteers via a newspaper advertisement to take part in a learning experiment at Yale University. The participant was always assigned the role of “teacher”. Mr Wallace, a confederate, played the role of “learner”. The participant was instructed to punish the learner (who was in another room) each time he made a mistake by administering an electric shock that increased in intensity by 15 volt increments up to a maximum of 450 volts. The participant did not know until the end of the experiment that the shocks were not real, and the screams were pre-recorded. Findings All participants continued to at least 300 volts. 65% of participants (26 out of 40) went up to the maximum 450 volts. Most participants complained and said they didn’t want to continue. Many became very anxious and distressed (trembling, shaking etc.). Only five participants (12%) stopped at 300 volts. 10. Explain two ethical issues raised by Milgram’s research. (2 + 2) Informed consent: Because participants were deceived (e.g. told the study was about memory) they could not give their fully informed consent. Protection of participants: Milgram was criticised for not protecting his participants. Many experienced considerable distress during the experiment - stuttering, sweating and digging their fingernails into their own flesh. One participant experienced a seizure. 11. Explain why it is sometimes necessary to deceive participants in social influence research. (2) It may be necessary because if participants new the aim, they might change their behaviour, which would undermine the study’s validity, e.g. telling participants the study was about conformity. 12. Explain two ways of dealing with ethical issues raised in Milgram’s research. (2 +2) Thoroughly debriefing participants: telling them about the aims of the study and giving them the option to withdraw their results from the study once they have this information (a form of retrospective informed consent). Presumptive consent: obtain the views from a number of people regarding the acceptability of a proposed research procedure or study. Their views could be taken as evidence of how people in general would respond to participating in the research study. 17 Social Psychology 13. What are two explanations of why people resist pressure to conform? (3 + 3) 4 Dissent: Research has shown that conformity will be significantly reduced if the majority is not seen to be unanimous in its opinion. As soon as the unanimity of the majority group is weakened, non-conformity is more likely to be seen as an appropriate response. The dissenter represents a form of social support and liberates others from the need to conform to the majority. Individual differences: Evidence generally shows that those with high internal locus of control are less likely to conform than those with high external LOC. This may be because they have more self-confidence to resist social influence. They are also more likely to be leaders. 14. What are two explanations of why people might resist pressures to obey authority? (3 + 3) FEELING RESPONSIBLE FOR ACTIONS According to Milgram’s agency theory, people are more likely to resist authority when they feel autonomous, that is, when they feel responsible for the consequences of their behaviour. For example, obedience levels decreased to 30% when the participant held the learner’s hand down. presumably because the participant felt more responsible. DISOBEDIENT MODELS There is evidence that when a person is provided with role models for resisting authority, they are more likely to disobey. Seeing other people disobey shows that it’s possible to disobey, as well as how to disobey. For example, Milgram found obedience rates decreased to 10% when ‘the teacher’ (participant) was paired with two other teachers (confederates) who refused to continue after 150v and 210v.) 15. Explain what is meant by the term locus of control. (4) Locus of control refers to the sense of control people have over their lives. Locus of control is usually measured on a scale. Those with a high internal locus of control largely believe that their actions are their own choice and responsibility. Those with a high external locus of control see their actions as resulting largely from factors outside their control such as luck or fate. 16. Explain how locus of control influences independent behaviour. (4) People with high internal LOC feel they are in control of the events in their lives and are responsible for their actions. People with high external locus of control feel the events in their lives are controlled by external forces. Evidence generally shows that those with high internal LOC show more independent behaviour than those with high external LOC. This may be because they have more self-confidence to resist social influence. They are also more likely to be leaders. Those with high external LOC have lower self-esteem and need more social approval, making independent behaviour less likely to occur. 17. Outline how social influence research helps us to understand social change. (6) Minority influence is important for the introduction and acceptance of new ideas and ways of doing things. A minority can challenge the beliefs and values of those initially in the majority, causing them to revise their beliefs. Minority influence is most effective when it shows both consistency (Moscovici) and flexibility (Nemeth). Once a few members of the majority start to move towards the minority position there is a ‘snowball effect’ and the influence of the minority begins to gather momentum (Clark 1998). When a person is provided with role models for resisting authority, they are more likely to disobey. Seeing other people disobey shows that it’s possible to disobey, as well as how to disobey. 18 Social Psychology 18. Explain what is meant by the term minority influence. (2) A form of social influence where people reject the established norm of the majority of group members and move to the position of the minority. Minority influence was demonstrated in Moscovici’s study in which participants moved to the position of the minority in 8.42% of the trials. 19. Outline research into minority influence. (6) Moscovici et al. (1969: A group of six people were asked to name the colour of slides that were various shades of blue. Two of the six were confederates. Moscovici found that the naive participants named the slides as ‘green’ in 8.42% of the trials when two confederates answered green on every trial. However, Nemeth (1987) argued that flexibility is more crucial than consistency. He found that when the consistent minority (a confederate) moved some way towards the majority position, he had more influence than when he remained consistent and refused to change his position. 20. Explain the difference between minority and majority influence. (4) 1. One difference between the two is the size of the group causing the influence. • Majority influence occurs when people adopt the behaviour, attitudes or values of the larger group. • Minority influence occurs when people reject the established norms of the majority of group members and move to the position of the few. 2. Majority influence often involves public compliance, rather than private acceptance. Whereas minority influence involves internalisation or conversion. 19 Social Psychology Questions that require knowledge of research methods 1. Outline one method that psychologists have used to study conformity. (2) Laboratory experiments, where confederates deliberately give the wrong answer to see if the naive participant conforms, e.g. Asch’s study. 2. Explain two limitations of lab-based studies into conformity. (2 +2) Lab experiments of conformity often involve trivial tasks and artificially created groups, which limit their ecological validity. Hence findings cannot be generalised to the real world. Because of the artificiality of the situation, demand characteristics are more likely. Thus, participants may respond in the way they think the experimenter expects. 3. Suggest one way of overcoming a limitation of lab studies of conformity. (2) To overcome lack of ecological validity the researcher could conduct the experiment in the real world, by setting up a field experiment so people behave as they normally would. 4. What are two strengths of lab studies of conformity? (2) High levels of control make it easier for the researcher to show the effect of the independent variable on the dependent variable, i.e. to show cause and effect. Because laboratory experiments of conformity are conducted under controlled conditions, they can be replicated. Therefore their reliability can be assessed. 5. Explain one advantage of conducting obedience research outside a laboratory setting. (2) The research may be high in ecological validity, because people behave as they normally would. This means the results can be generalised beyond the research setting. 6. Explain one limitation of conducting obedience research outside a lab. (2) Lack of control. Other factors (extraneous variables) may have influenced the outcome. 7. Apart from ethical issues, give one strength and one limitation of Milgram’s methodology. (2 +2) Strength: Because his study was conducted under controlled conditions, it can easily be replicated. Therefore reliability can be assessed. Limitation: Critics claim the study lacked ecological validity– the research situation was not like real life. The experimenter/participant relationship is unique, unlike relationships in the outside world - thus limiting generalisation of the findings. 8. Explain one way locus of control has been investigated. (3) Rotter devised a questionnaire of 23 forced choice items that measured an individual’s sense of personal control over events in their life. At one end of the scale are those with a high internal LOC, and at the other end, are those with high external LOC. (For example, “Who gets to be the boss depends on who was lucky enough to be in the right place.”) 20 Social Psychology Application of knowledge: Thinking on the spot! For some questions you need to apply your knowledge and understanding of psychology to a novel situation – what I term the “Thinking on the spot!” questions. You can’t predict these questions but you can develop your ability to answer them. Tips for answering: 1. Read the question two times. Write down the areas of knowledge that you could include in the answer. 2. For each item of knowledge, refer to the scenario (the description of a person or situation described in the question). Take two or three aspects of the scenario and relate these to your knowledge. 3. If appropriate give findings from a study that demonstrates what you have written. The most important advice of all: It is essential that you explicitly relate your knowledge to the situation or person described in the question. The following examples might help. I have included some suggestions of relevant psychological knowledge and how you can relate this knowledge to the novel situation described in the question. The answers are longer than you would have time for in the exam – but hopefully give you ideas of how to tackle the questions. TYPES OF CONFORMITY If you are asked to explain the type of social influence that is shown in a novel situation you should say whether it is normative or informational. Briefly outline either normative or informational social influence. Justify your choice with examples from the scenario, and then say whether the type of conformity is likely to result in compliance or internalisation. 1. Maya is part of a close-knit group of girls in the sixth form at her college. It is great to know she always has friends to sit next to during class, lunch breaks and free periods. After college she usually walks home with two of the girls. When they get together one of their favourite pastimes is gossiping about other girls in the college, and sometimes they can be quite cruel. Maya feels uncomfortable with this kind of conversation, and is usually quiet but sometimes she joins in, commenting on and perhaps laughing at another girl’s clothes or hair style. Identify the type of social influence illustrated in the situation described above. Refer to features of the situation to justify your answer. (3) Normative social influence – conforming in order to be liked and to avoid rejection. Maya clearly wants to be part of the group (‘it is great to know she always has friends to sit next to.’) Although she feels uncomfortable she does join in the gossip. This kind of conformity usually leads to compliance – public conforming to the behaviours of the group but privately disagreeing. 2. Gideon is invited to his friend David’s house for an evening meal. David’s mother serves him a first course of prawns cooked in their shells. Gideon is keen to try them, but is worried about how to take off the shells because the only fish he ever has at home is fish fingers. He discretely observes how others at the dinner table tackle their food before starting the dish himself. Identify the type of social influence illustrated in the situation described above. Refer to features of the situation to justify your answer. (3) Informational social influence – conforming because of the need to be right in an ambiguous situation. Gideon doesn’t know how to eat the prawns and looks to others for the right way to peel them. Informational social influence usually leads to internalisation – both public and private agreement. It is likely that Gideon will adopt this behaviour in the future. 21 Social Psychology OBEDIENCE Josie has just started a new job in a local cafe. One of its specialties is afternoon tea, which consists of two scones and two very small pots of clotted cream and jam. On her second day, Josie clears a table and empties the remaining cream and jam from the two pots into the used food bin. Her boss tells her that she mustn’t waste the cream and jam, and that she is to put any remaining into clean pots and top them up ready for the next customer. Josie thinks this is not a very hygienic thing to do, and also wonders what the customers would think. But she doesn’t say anything, and instead does as she is told. Using your knowledge of why people obey, explain Josie’s behaviour. (4) Josie obeys her boss’s instructions because she perceives his authority as legitimate and she has been socialised since childhood to obey authority. She may also be in the agentic state: she sees herself as an agent of authority. As a result she does not feel responsible for her actions – even though she thinks the practice is unhygienic. Under what circumstances might Josie refuse to obey? (4) If another employee disobeyed the boss (e.g. refused to re-use the jam and cream), Josie might refuse to obey. This is because we are more likely to disobey when we have seen others resist authority. Seeing other people (our peers) disobey shows that it’s possible to disobey. Milgram found that when the participant was paired with two other teachers (confederates) who refused to continue after 150v and 210v, obedience decreased to 10%. If she talked to other employees about the practice. When people have time to discuss an issue they are more likely to resist pressure to obey. RESISTING PRESSURES TO CONFORM It is the morning of Samir’s mock exam for A-level History. The group of nine students are in the class early, well before the lesson begins. Their teacher is at the daily morning staff briefing and isn’t due for 20 minutes. One of the students notices that the mock exam papers are on the teacher’s desk, and jokingly asks if anyone wants a look. After a few seconds everyone in the group except for Samir takes a copy. A couple of the students try and coax him, but he refuses. Using your knowledge of psychology, suggest why Samir doesn’t conform. (5) Samir might have high internal locus of control. People with high internal LOC feel responsible for their actions and are usually more independent: they are confident and have high self-esteem. This means that Samir is less likely to go along with the group – he isn’t reliant on the group’s approval. Another reason may be that he thinks it is morally wrong to cheat – and studies have found people with a high level of moral development show independent behaviour. SOCIAL CHANGE The popularity of cycling has greatly increased over the past few years – with more adults using bikes to get to work and more young people using them for school. Twenty years ago very few cyclists wore helmets. By 2009 the figures had risen to 50% people wearing helmets most of the time and 35% reporting that they wear them for all trips. Although at the present time there is no legislation concerning the wearing of helmets, surveys report that 62% of people say they would support the introduction of helmet laws. Using your knowledge of psychology, explain the change in attitudes and behaviour towards the wearing of cycling helmets. (5) The change in attitudes and behaviour towards wearing helmets started with minority influence. A few people believed that the wearing of helmets would decrease road deaths. The minority was consistent and flexible in the beliefs – and were clearly not 22 Social Psychology acting out of self-interest. Moscovici found that a consistent minority convinced participants that blue slides were green on 8.4% of trials. Due to the snowball effect, once a few members of the majority start to move towards the minority position then the influence of the minority begins to gather momentum. At some stage people were influenced by peers who wore helmets – it made them feel part of a group (social identity theory). There was also informational social influence: people thought people who wore helmets had more information about road accidents. In this case, the safety arguments were internalised, and likely to be permanent. 23 Individual Differences What you need to know • • • • • Definitions of abnormality, including deviation from social norms, failure to function adequately and deviation from ideal mental health.

(4) 2 Individual Differences 12 mark question: Outline and evaluate two or more definitions of psychological abnormality. Three definitions are given in the specification. For a 12 mark question you could either write in detail about two definitions or in less detail about three definitions. DEVIATION FROM SOCIAL NORMS This definition views abnormality in terms of the breaking of society’s standards or norms. Abnormal behaviour can be seen as behaviour that deviates from or violates society’s implicit or explicit rules and moral standards, e.g. standing too close to people when you are talking to them, wearing clothes inappropriate to the situation. However, two limitations of this definition are: 1. Social norms are era dependent (vary over time) as attitudes change. For example, homosexuality was viewed as a psychiatric disorder until the 1960’s. Since then attitudes have changed, and homosexuality is no longer seen as a mental disorder. 2. The deviation from social norms definition is bound by culture. Social norms vary between cultures. Behaviour seen as a deviation in one society may appear quite acceptable in another, e.g. the expression of grief in response to the death of a loved one. FAILURE TO FUNCTION ADEQUATELY This definition views abnormality as the failure to experience the normal range of emotions or to engage in the normal range of behaviour. Indicators of the failure to function adequately, as identified by Rosenhan & Seligman, include: 1. dysfunctional (maladaptive) behaviour – prevents an individual from achieving life goals 2. observer discomfort – where another’s behaviour causes discomfort and distress to the observer, e.g. talking very loudly to oneself on a bus 3. unpredictable behaviour – variable and uncontrolled 4. irrational behaviour – behaviours that are difficult to understand, e.g. laughing wildly at a funeral However, two limitations of this definition are: 1. It ignores the social context of the behaviour. Behaviour must be seen within specific situational contexts. Some apparently dysfunctional behaviour might be adaptive and functional for the individual, e.g. going on a hunger strike for a just cause. 2. Some psychological disorders do not prevent a person from functioning adequately. Personality disorders related to psychopathy can appear normal most of the time, e.g. Dr. Harold Shipman who killed over 200 patients. DEVIATION FROM IDEAL MENTAL HEALTH This definition identifies characteristics people should possess in order to be considered normal. Jahoda identified six criteria by which mental health might be defined: 1. positive view of self – high self-esteem and strong sense of identity 2. personal growth and self-actualisation 3. autonomy – being independent and self-regulating 4. accurate perception of reality 5. resistance to stress 6. mastery of the environment Abnormality is seen as the deviation from these ideals. However, two limitations of this definition are: 1. Jahoda’s view of mental health is culture-bound, largely based on and limited to individualist cultures, in particular North American culture. Collectivist societies that emphasise cooperation amongst their members would reject the importance of selfactualisation as a criterion for mental health. If we apply Jahoda’s criteria to other 3 Individual Differences cultures or sub-cultures it would result in a higher incidence of abnormality than is actually the case. 2. Few people would match all the criteria laid down by Jahoda – thus the majority of the population would be classified as abnormal. You might want to know Might be a good idea to be familiar with other limitations of deviation from social norms, for a short question where you are asked to apply your understanding. • This definition has allowed serious abuse of human rights to occur. For example, in the Soviet Union after the Second World War, political dissenters were frequently classified as mentally ill and sent to mental hospitals. • Social deviancy is not necessarily a bad thing. Some people are socially deviant because they have chosen a non-conformist lifestyle and others because their behaviour is motivated by high principles, e.g. deviants in Nazi Germany who spoke out against atrocities or risked their lives. • This definition ignores the context of behaviour. • This definition doesn’t sufficiently distinguish between eccentric and abnormal behaviour. 4 Individual Differences 12 mark question: Outline and evaluate the biological approach to psychopathology. KEY ASSUMPTIONS Brain dysfunction: Psychological disorders may result from damage to the brain. For example, some patients with schizophrenia have enlarged ventricles in their brains, indicating shrinkage of brain tissue. Genetic inheritance: Most behaviours, whether normal or disordered, involve a component inherited from the biological parents. The presence of certain genes can make people more vulnerable to disorders. For example, some people are genetically predisposed to develop depression or schizophrenia. Biochemistry: Psychological disorders may be due to an imbalance of chemicals - there may be too much or too little of certain neurotransmitters and hormones. For example, low levels of serotonin have been linked to depression. An excess of the neurotransmitter dopamine has been associated with schizophrenia. 1. Evidence used to support the biological model includes twin studies. For example, Gottesman (1991) reported a concordance rate of 48% between identical twins (MZ) for schizophrenia, compared to I7% for fraternal (DZ) twins. 2. However, the concordance rate is never 100% - therefore environmental factors are always involved. EVALUATION Strengths 1. The biological approach has led to a range of drug treatments that alter the body’s biochemistry. For example, Prozac, an antidepressant drug, increases the level of the neurotransmitter serotonin. Antidepressant drugs appear to be effective in 6575% of cases. These treatments can relieve distressing and at times life-threatening symptoms. 2. The biological approach is testable. It is backed up by an enormous amount of research (including the recent use of brain scans) and this has increased understanding of the possible contribution of biological factors to mental disorders. Limitations... however 1. The biological approach is reductionist: complex mental and emotional processes are unlikely to be caused solely by genes and neurotransmitters. At most, biological factors predispose people to developing psychological disorders which are triggered by environmental factors (the diathesis-stress model). 2. Cause or consequence: It is difficult to determine whether chemical imbalances are a cause or a consequence of a mental disorder, e.g. low levels of serotonin may be a consequence of depression rather than the cause. You might need to know Twin studies compare identical twins (MZ’s: monozygotic) who have the same genes with fraternal twins (DZ’s: dizygotic) who share only 50% of their genes. If genetic factors are important, the concordance rate should be higher in identical than in fraternal twins. You might like to think about A further limitation of the biological approach: the biological approach may lead to the labelling of patients – it is more likely to identify the whole person – a ‘schizophrenic’, rather than a person with schizophrenia. 5 Individual Differences 12 mark question: Outline and evaluate the psychodynamic approach to psychopathology. KEY ASSUMPTIONS 1. Abnormal behaviour is the result of unconscious and repressed conflicts from childhood. Mental disorders may result from experiences during the oral, anal and phallic stages. For example, depression may be linked to the loss of a parent (especially the mother) before the age of five years. Fixation during the anal stage may lead to an obsession with cleanliness, e.g. obsessive-compulsive disorder. 2. The personality consists of the id, ego and superego. Mental disorders occur when the ego fails to reconcile the opposing forces of the id and the super ego. An unchecked id may result in conduct disorders in childhood and psychopathic behaviour in adulthood. An overly powerful superego can lead to neurosis, such as phobias and obsessional behaviour. 3. Anxiety is controlled by defence mechanisms such as repression, denial, projection and displacement. Mental disorders often represent an exaggerated use of defence mechanisms, e.g. projection can lead to paranoia. EVIDENCE 1. Freud supported his theories with case studies – e.g. Anna O and Little Hans. 2. However, although case studies provide in-depth qualitative data, they rely heavily on the researcher’s interpretations and thus are open to bias. The accuracy of childhood memories is also open to question. Thus, case studies may not be reliable. EVALUATION Strengths 1. The concept of the unconscious has had an enormous impact on psychology in general and the study of abnormality in particular. Many psychologists agree that unconscious processes influence behaviour. 2. The importance of childhood experiences in the development of mental disorders is supported by evidence. Bifulco et al. (1992) found evidence that children whose mothers died in childhood were more likely than other children to experience depression later in life. Limitations...however 1. Many argue that the psychodynamic approach is not scientific. The assumptions refer to variables that must be inferred, rather than observed directly (e.g. the unconscious, defence mechanisms). Therefore, it is difficult to test this theory - it is nonfalsifiable. 2. Freud did not study children directly. He worked with neurotic adults and then explained their problems in terms of their early experiences. 3. The assumption that abnormal behaviour is the result of unconscious and repressed conflicts from childhood has been criticised for being deterministic. You might like to know According to the psychodynamic approach, in childhood the ego is not developed enough to deal with very distressing or painful experiences, and therefore they are repressed. In adulthood, previously unexpressed anger is directed towards the self, causing depression. 6 Individual Differences 12 mark question: Outline and evaluate the behavioural approach to psychopathology. KEY ASSUMPTIONS 1. Abnormal behaviour is learned in the same way as normal behaviour. All disorders are maladaptive behaviours, arising from conditioning, either classical or operant. 2. Classical conditioning involves learning an association between a neutral stimulus (e.g. a dentist) and an unconditioned stimulus (e.g. pain). The fear response generalises to the previously neutral stimulus (now a conditioned stimulus). Thus, phobias may be learned through classical conditioning. 3. Operant conditioning: ‘Behaviour is shaped and maintained by its consequences’ (Skinner). Consequences may be positive or negative reinforcement, or punishment. Thus, depression results from a lack of positive reinforcements (e.g. approval, friendships) or an excess of negative experiences (punishments). EVIDENCE 1. According to the behavioural approach, the same laws of learning apply to human and non-human animals; therefore a lot of research is carried out on non-human animals (e.g. rats and pigeons). 2. However, it is questionable whether findings from rats can be generalised to humans. Humans differ from animals in important ways, e.g. the role of cognitive factors such as language. Research with humans has not always supported behaviourist claims. Only 2% of water-phobic children claimed to have had a direct conditioning experience involving water (Menzies & Clarke, 1993). EVALUATION Strengths 1. The behavioural approach has led to therapies that have been successful in treating mental disorders, such as the use of systematic desensitisation for phobias. The success of the treatments provides support for the model. 2. The behavioural model recognises the importance of the environment. Thus, it can account for cultural differences, e.g. eating disorders are more common in Western cultures, where slimness is presented as the ‘ideal’. Limitations…however The behavioural approach is reductionist: 1. It minimises the role played by internal processes, such as thoughts and feelings. There is a great deal of evidence that individuals who suffer from depression or panic attacks have distorted thinking patterns – these would be difficult to explain by the behavioural approach. 2. It ignores biological factors. For example, there is evidence that genetics make individuals more vulnerable to developing schizophrenia. Other evidence implicates the role of neurotransmitters, e.g. the role of serotonin in depression. You might like to know The behavioural approach has been extended to include social learning theory. The key idea of SLT is that people learn maladaptive behaviour through observation and imitation of others (models), especially if they observe the behaviour being rewarded (vicarious reinforcement). For example, a child may learn a phobic response from observing a parent’s fear of blood. 7 Individual Differences 12 mark question: Outline and evaluate the cognitive approach to psychopathology. KEY ASSUMPTIONS 1. The cognitive approach assumes that people’s thoughts direct their emotions and behaviour. Mental disorders result from irrational and negative cognitions. For example, a person believes she/he is worthless and this thinking leads to feelings of depression. 2. Thinking can be distorted in many ways, leading to cognitive biases: • magnification of difficulties and failures • minimisation of successes and achievements • over-generalisation – drawing a sweeping conclusion on the basis of a single event 3. Beck used the term cognitive triad to refer to three main forms of negative thinking, about (1) the self (2) the world (3) the future. According to Beck these automatic and maladaptive thought patterns can lead to depression. EVIDENCE 1. The questionnaire method is often used to assess people’s thinking patterns, e.g. the Beck Depression Inventory. Lewinsohn et al. (2001) found that students who had negative thoughts 12 months earlier were significantly more likely to become clinically depressed than those whose thoughts had been realistic. 2. However, a limitation of questionnaires is that people may not answer truthfully – they may either under-report or exaggerate their negative thinking. EVALUATION Strengths 1. Successful treatment: Research indicates that Beck’s cognitive therapy is as successful as antidepressant drugs in treating depression. This, in itself, provides support for the cognitive model. 2. Many would argue that the emphasis on the present rather than the past is a strength of the cognitive approach (compared to the psychodynamic approach). Limitations...however 1. The cognitive approach has been criticised for viewing negative and irrational cognitions as the cause of mental disorders, when they may the consequence of having a mental disorder. Thus, negative emotion may cause the negative thinking. 2. The cognitive approach overlooks the role of biological factors such as chemical imbalances. For example, depression has been linked with low levels of serotonin and higher than average levels of cortisol. 8 Individual Differences 10 or 12 mark question: Discuss the use of drugs to treat psychological disorders. DESCRIPTION 1. Antipsychotics: Drugs used in the treatment of schizophrenia. They reduce symptoms such as hallucinations, delusions and thought disorders. Antipsychotics act by reducing dopamine activity in the brain. Examples include chloropromazine and clozapine. 2. Anti-depressants: Drugs used in the treatment of depression. These drugs raise serotonin levels in the brain, either by reducing the rate of re-absorption of serotonin, or by blocking the enzyme that breaks down serotonin. Examples include monoamine-oxidase inhibitors (MAOI’s) and selective serotonin reuptake inhibitors (SSRI’s, for example, Prozac). 3. Lithium: Used for bipolar depression. (A disorder where the person has periods of clinical depression followed by periods of mania). Lithium can stabilise the condition. EVALUATION Strengths 1. Drugs can be effective in suppressing disabling and life-threatening symptoms of schizophrenia and severe depression, and many people are able to live normal lives because of drug therapy. (however, many patients do not respond to drug therapy.) 2. Drug therapy confirms the view of the person as a patient, and takes away individual responsibility and/or blame for the disorder (however, being labelled as schizophrenic or depressive can lead to stigmatising.) Limitations 1. However, drugs only treat the symptoms of a disorder, through their effects on the biological changes in the brain. They are therefore a reductionist treatment that ignores any cognitive, emotional or environmental influences. In the case of schizophrenia, symptoms return in about 80% of patients who come off the drugs. 2. Most drugs have problems of side effects and dependence, which need to be carefully managed. For example, SSRIs (e.g. Prozac) have been associated with outbursts of violence and suicides. 3. Ethical issues in drug therapy include the problem of side effects and the ability (or not) of people with serious conditions such as severe depression or schizophrenia to give fully informed consent to treatment. Note: For a 6 mark question “Discuss the use of drugs to treat psychological disorders” – leave out the description, and just include the evaluation (strengths and limitations). You may need to know Drugs that are used to treat anxiety disorders are described in Biological Psychology and include: Benzodiazepines (BZ’s) work by reducing activity of the neurotransmitter serotonin and reducing arousal of the central nervous system. BZ’s are the most common drugs used to treat anxiety, and include Valium and Librium. Beta-blockers do not enter the brain but reduce activity of the sympathetic nervous system in pathways around the body and block receptors on the heart which are stimulated by noradrenaline. Thus, they slow the heart rate and reduce blood pressure. Beta-blockers have been found to be effective for performance anxiety, e.g. musicians and certain snooker players. 9 Individual Differences 8 mark question: Discuss the use of electroconvulsive therapy (ECT) to treat psychological disorders. DESCRIPTION 1. The patient is on a bed. An electrode is placed above the temple of the non-dominant side of the brain (unilateral ECT). 2. The patient is injected with a short-acting anaesthetic (so they are not conscious during the treatment) and given a strong muscle relaxant. 3. A small amount of electric current (between 70 and 130 volts), lasting about half a second is passed through the brain. 4. The electric current produces convulsions – lasting up to one minute, which affect the entire brain. (The spasms are barely perceptible to onlookers.) 5. Repeated 3 times per week for up to 4 weeks EVALUATION Strengths ECT can be an effective antidepressant treatment for patients unresponsive to other therapies (and especially when suicide is an issue). Around 60-70% of ECT patients improve after treatment (although there is a high percentage of relapse within six months of treatment). Limitations...however 1. ECT can have side effects. ECT can lead to long-term memory impairment, anxiety and headaches. 2. There are serious ethical issues with ECT. Individuals with severe depression may not fully grasp the nature and consequences of ECT, and so cannot give fully informed consent. 10 Individual Differences 12 mark question: Discuss the use of psychoanalysis to treat psychological disorders. DESCRIPTION OF TREATMENT The aim of psychoanalysis is to make “the unconscious conscious” – to uncover material repressed into the unconscious. Techniques include free association and dream analysis. Free association: • The client is encouraged to express anything that comes into their mind, no matter how trivial • Talking freely allows ego defences to be lowered and repressed material accessed • The therapist intervenes on occasions – to encourage further reflection, or to make interpretations Dream analysis: • Dreams are the “royal road to the unconscious”. The therapist analyses and interprets the manifest content (the content as reported by the dreamer), in order to uncover the latent content (the actual meaning of the dream) • The therapist hopes to identify significant repressed conflicts and unconscious wishes (often sexual or aggressive) EVALUATION Strengths 1. Many therapies, for both children and adults, have been influenced by psychoanalysis, and its emphasis on the importance of childhood experiences and the unconscious. 2. Evidence suggests that psychoanalysis is as effective as other psychological therapies, especially for depression and anxiety disorders. Dossman et al. (1997) in a study of 666 patients found that therapy decreased medical visits by 30%, and reduced lost work days by 40% and days in hospital by 66%. (Deciding the effectiveness of any therapy is fraught with difficulties, e.g. people have different ideas of what constitutes successful therapy.) Limitations 1. however, psychoanalysis is usually very long lasting (months or years) and is expensive, therefore is not accessible for many social groups (for example, the lowpaid, and unemployed). 2. Psychoanalysis requires clients to be articulate and insightful – thus, it may not be suitable for all personality types. 3. Psychoanalysis is unlikely to be effective with some disorders – for example, schizophrenia, where the individual usually does not have insight into their condition. 4. The original model over-emphasised childhood influences and ignored the everyday problems faced by the adult patients. however, current psychodynamic therapy recognises this. You might like to know Transference is an important part of psychoanalysis. This involves the patient projecting conflicts and feelings from the past (often to do with the patient’s parents) onto the analyst. This process reveals to both the analyst and the patient the childhood origins of some of their anxieties and fears. 11 Individual Differences 10 mark question: Discuss the use of systematic desensitisation to treat psychological disorders. DESCRIPTION Systematic desensitisation is used in the treatment of phobias, and is based on classical conditioning. The aim is to extinguish the conditioned association between fear and the situation or object (a form of counter-conditioning). The fear response is replaced by the alternative response of relaxation. In the case of a phobia: 1. The therapist teaches the client deep relaxation techniques. 2. The therapist and client construct a desensitisation hierarchy – a series of imagined scenes, each one causing a little more anxiety that the previous one. 3. The therapist asks the client to visualise the least feared situation. Simultaneously the client performs the deep relaxation procedure. 4. Once the client feels comfortable at that level, they are asked to imagine the next situation in the hierarchy. The same procedure is repeated. (If the client becomes upset, they can return to an earlier stage and regain their relaxed state.) 5. Over a series of sessions, the client will cope with every level of the hierarchy. EVALUATION Strengths 1. Systematic desensitisation can be extremely effective in the treatment of simple phobias. Success rates of between 60 and 90% have been reported for spider phobics and injection phobics (Barlow et al., 2003) 2. The therapy involves the client in an active manner (e.g. creating their own anxiety hierarchy), and this should help him/her feel in control. Limitations 1. However, like all behavioural therapies, systematic desensitisation focuses on symptoms rather than any deeper underlying causes. However, there is little evidence that the symptoms reappear in another form (symptom substitution), and the symptoms are the problem after all (e.g. the fear of dogs). 2. SD relies on the client’s ability to be able to imagine the fearful situation. If a client has difficulty in creating a vivid image, SD is not effective. You might like to know Critics argue that although SD may be effective in the therapeutic situation, it may not work in the real world. However, there is evidence that the ability to tolerate imagined stress situations is followed by a reduction in anxiety in real-life situations (Emmelkamp, 1994). 12 Individual Differences 12 mark question: Discuss the use of Cognitive Behavioural Therapy to treat psychological disorders. DESCRIPTION CBT assumes that problems in thinking underlie psychological disorders. The aim of Beck’s therapy is to challenge irrational and dysfunctional thought processes (about the self, the world and the future), and to replace them with more realistic and optimistic ones: 1. The therapist helps the client identify negative thoughts, e.g. “No one finds me attractive and they never will.” 2. The therapist challenges the dysfunctional cognitions by drawing attention to positive examples that contradict the client’s negative assumptions – this is referred to as reality testing. 3. The therapist may use behavioural techniques to encourage more positive thinking. For example, the client is set a list of small goals to be achieved – e.g. to ask someone to meet for coffee or a drink during the following week. These achievements increase the client’s self-efficacy. EVALUATION Strengths 1. CBT is effective as a treatment for depression and anxiety. There is evidence that the beneficial effects of CBT on depression last longer than those of antidepressant drugs (Butler et al. 2006). 2. CBT is recognised as being effective enough to be made available through the NHS. 3. Courses of CBT are generally limited to a number of sessions over a few weeks. It is therefore less time consuming and more cost effective than psychoanalytic therapies. 4. There are no side effects or dependency issues with CBT as there are with drug therapies. Limitations however.... 1. CBT is not suitable for all conditions, e.g. schizophrenia, and CBT is less effective than behavioural therapies for treating phobias. 2. Depression may be based on an accurate perception of reality (depressive realism) – it is important that the therapist does not give the impression that depression is always unjustified. You might like to know In a review of the overall benefits of CBT, Kopelowicz & Liberman (1998) found that CBT moderately improved the symptoms of schizophrenia in 50% to 60% of sufferers, but only when it was used in conjunction with drug therapy. 13 Individual Differences Short questions Definitions of abnormality 1. Explain the deviation from social norms definition of abnormality. (3) This definition views abnormality in terms of the breaking of society’s standards or norms. Abnormal behaviour can be seen as behaviour that deviates from or violates society’s implicit or explicit rules and moral standards, e.g. standing too close to people when you are talking to them, wearing clothes inappropriate to the situation. 2. What are two limitations of the deviation from social norms definition of abnormality? (2 + 2) 1. Social norms are era dependent (vary over time as attitudes change). For example, homosexuality was viewed as a psychiatric disorder until the 1960’s. Since then attitudes have changed, and homosexuality is no longer seen as a disorder. 2. Deviation from social norms is bound by culture. Behaviour seen as a deviation in one society may appear quite acceptable in another, e.g. the expression of grief in response to the death of a loved one. 1. 3. Explain the failure to function adequately definition of abnormality. (3) This definition views abnormality as the failure to experience the normal range of emotions or to engage in the normal range of behaviour. Indicators of the failure to function adequately, as identified by Rosenhan & Seligman, include: 1. maladaptive (dysfunctional) behaviour – prevents an individual from achieving life goals 2. observer discomfort – where another’s behaviour causes discomfort and distress to the observer, e.g. talking very loudly to oneself on a bus 3. unpredictable behaviour – variable and uncontrolled 4. irrational behaviour – behaviours that are difficult to understand, e.g. laughing wildly at a funeral 4. What are two limitations of the failure to function adequately definition of abnormality? (2 + 2) 1. It ignores the social context of the behaviour. Behaviour must be seen within specific situational contexts. Some apparently dysfunctional behaviour might be adaptive and functional for the individual, for example, going on a hunger strike for a just cause. 2. Some psychological disorders do not prevent a person from functioning adequately. Personality disorders related to psychopathy can appear normal most of the time, e.g. Dr. Harold Shipman, who killed over 200 patients. 5. Explain the deviation from ideal mental health definition of abnormality. (3) This definition identifies characteristics people should possess in order to be considered normal. Jahoda identified criteria by which mental health might be defined, including: 1. positive view of self – high self-esteem and strong sense of identity 2. personal growth and self-actualisation 3. autonomy – being independent and self-regulating 4. accurate perception of reality 5. resistance to stress 6. mastery of the environment Abnormality is seen as the deviation from these ideals. 6. What are two limitations of the deviation from ideal mental health definition of abnormality? (2 + 2) 1. Jahoda’s view of mental health is culture-bound, largely based on and limited to individualist cultures, in particular North American culture. Collectivist societies that emphasise cooperation amongst their members would reject the importance of self-actualisation as a criterion for mental health. If we apply Jahoda’s criteria 14 Individual Differences to other cultures or sub-cultures it would result in a higher incidence of abnormality than is actually the case. 2. Few people would match all the criteria laid down by Jahoda – thus the majority of the population would be classified as abnormal. Approaches to psychopathology 1. Outline assumptions of the biological approach to psychopathology. (6) Brain dysfunction: Psychological disorders may result from damage to the brain. For example, some patients with schizophrenia have enlarged ventricles in their brains, indicating shrinkage of brain tissue. Genetic inheritance: Most behaviours, normal and disordered, involve a component inherited from the biological parents. The presence of certain genes can make people more vulnerable to disorders. For example, some people are genetically predisposed to develop depression or schizophrenia. Biochemistry: Psychological disorders may be due to an imbalance of chemicals there may be too much or too little of certain neurotransmitters and hormones. For example, low levels of serotonin have been linked to depression. An excess of the neurotransmitter dopamine has been associated with schizophrenia. 2. What is one strength and one limitation of the biological approach to psychopathology? (3 + 3) Strength: The biological approach has led to a range of drug treatments that alter the body’s biochemistry. For example, Prozac, an antidepressant drug, increases the level of the neurotransmitter serotonin. Antidepressant drugs appear to be effective in 65-75% of cases. Limitation: The biological approach is reductionist: complex mental and emotional processes are unlikely to be caused solely by genes and neurotransmitters. At most, biological factors predispose people to developing psychological disorders which are triggered by environmental factors (the diathesisstress model). 3. Outline assumptions of the psychodynamic approach to psychopathology. (6) 1. Abnormal behaviour is the result of unconscious and repressed conflicts from childhood. Mental disorders may result from experiences during the oral, anal and phallic stages. For example, depression may be linked to the loss of a parent (especially the mother) before the age of five years. Fixation during the anal stage may lead to an obsession with cleanliness, e.g. obsessive-compulsive disorder. 2. The personality consists of the id, ego and superego. Mental disorders occur when the ego fails to reconcile the opposing forces of the id and the super ego. An unchecked id may result in conduct disorders in childhood and psychopathic behaviour in adulthood. An overly powerful superego can lead to neurosis, such as phobias and obsessional behaviour. 3. Anxiety is controlled by defence mechanisms such as repression, denial, projection and displacement. Mental disorders often represent an exaggerated use of defence mechanisms, e.g. projection can lead to paranoia. 4. What is one strength and one limitation of the psychodynamic approach to psychopathology? (2 + 2) Strength: The importance of childhood experiences in the development of mental disorders is supported by evidence. Bifulco et al. (1992) found evidence that children whose mothers died in childhood were more likely than other children to experience depression later in life. . 15 Individual Differences Limitation: Many argue that the psychodynamic approach is not scientific. The assumptions refer to variables that must be inferred, rather than observed directly (e.g. the unconscious, defence mechanisms). Therefore, it is difficult to test this theory - it is nonfalsifiable. 5. Outline assumptions of the behavioural approach to psychopathology. (6) 1. Abnormal behaviour is learned in the same way as normal behaviour. All mental disorders are maladaptive behaviours, arising from conditioning, either classical or operant. 2. Classical conditioning: involves learning an association between a neutral stimulus (e.g. a dentist) and an unconditioned stimulus (e.g. pain). The fear response generalises to the previously neutral stimulus (now a conditioned stimulus). Thus, phobias may be learned through classical conditioning. 3. Operant conditioning: ‘Behaviour is shaped and maintained by its consequences’’ (Skinner). Consequences may be positive or negative reinforcement or punishment. Thus, depression results from a lack of positive reinforcements (e.g. approval, friendships) or an excess of negative experiences (punishments). 6. What is one strength and one limitation of the behavioural approach to psychopathology? (2 + 2) Strength The behavioural approach has led to therapies that have been successful in treating mental disorders, such as the use of systematic desensitisation for phobias. The success of the treatments provides support for the model. Limitation The behavioural approach ignores biological factors. For example, there is evidence that genetics make individuals more vulnerable to developing schizophrenia. Other evidence implicates the role of neurotransmitters, e.g. the role of serotonin in depression. 7. Outline assumptions of the cognitive approach to psychopathology. (6) 1. The cognitive approach assumes that people’s thoughts direct their emotions and behaviour. Mental disorders result from irrational and negative cognitions. For example, a person believes she/he is worthless and this thinking leads to feelings of depression. 2. Thinking can be distorted in many ways, leading to cognitive biases: • magnification of difficulties and failures • minimisation of successes and achievements • over-generalisation – drawing a sweeping conclusion on the basis of a single event 3. Beck used the term cognitive triad to refer to three main forms of negative thinking, about (1) the self (2) the world (3) the future. According to Beck these automatic and maladaptive thought patterns can lead to depression. 8. What is one strength and one limitation of the cognitive approach to psychopathology? (2 + 2) Strength Successful treatment: Research indicates that Beck’s cognitive therapy is as successful as antidepressant drugs in treating depression This, in itself, provides support for the cognitive model. Limitation The cognitive approach has been criticised for viewing negative and irrational cognitions as the cause of mental disorders, when they may the consequence of having a mental disorder. Thus, negative emotion may cause the negative thinking. 16 Individual Differences 9. Explain one way in which psychologists have investigated the biological basis of abnormality. (3) One way is to compare identical twins (MZ’s: monozygotic) who have the same genes with fraternal twins (DZ’s: dizygotic twins) who have around 50% shared genes. For example, there is evidence of a higher concordance rate for schizophrenia between MZ twins than DZ twins - seen as support for the biological model. 10. Explain one way in which psychologists have investigated the psychodynamic approach to abnormality. (3) Evidence supporting the psychodynamic model comes from clinical case studies, an indepth study of an individual or group of people. Freud supported his theories with case studies, e.g. Anna O and Little Hans. 11. Explain one way in which psychologists have investigated the behavioural approach to abnormality. (3) According to the behavioural approach, the same laws of learning apply to human and non-human animals. Therefore, a lot of research is carried out on non-human animals, under controlled lab conditions (e.g. pigeons and rats), using the experimental method. For example, Skinner’s research into operant conditioning. 12. Explain one way in which psychologists have investigated the cognitive approach to abnormality. (3) The questionnaire method is often used to assess people’s thinking patterns, e.g. the Beck Depression Inventory. There is a great deal of evidence that compared to non-depressed people, depressed individuals are more negative in terms of themselves, the world, and the future. Treatments 1. Outline the use of drugs in treating abnormality. (4 or 6) Antipsychotics: Drugs used in the treatment of schizophrenia. They reduce symptoms such as hallucinations, delusions and thought disorders. Antipsychotics act by reducing dopamine activity in the brain. Examples include chloropromazine and clozapine. Anti-depressants: Drugs used in the treatment of depression. These drugs raise serotonin levels in the brain, either by reducing the rate of re-absorption of serotonin, or by blocking the enzyme that breaks down serotonin. Examples include monoamine-oxidase inhibitors (MAOI’s) and selective serotonin reuptake inhibitors (SSRI’s, for example, Prozac). Lithium: Used for bipolar depression. (A disorder where the person has periods of clinical depression followed by periods of mania) Lithium can stabilise the condition. 2. What is one strength and one limitation of the use of drugs in treating abnormality? (2 + 2) Strength Drugs can be effective in suppressing disabling and life-threatening symptoms of schizophrenia and severe depression, and many people are able to live normal lives because of drug therapy. (however, many patients do not respond to drug therapy.) Limitation Most drugs have problems of side effects and dependence, which need to be carefully managed. For example, SSRIs (e.g. Prozac) have been associated with outbursts of violence and suicides. 17 Individual Differences 3. Describe the use of ECT (electro-convulsive therapy) in treating abnormality. (4 or 6) 1. The patient is on a bed. An electrode is placed above the temple of the nondominant side of the brain (unilateral ECT). 2. The patient is injected with a short-acting anaesthetic (so they are not conscious during the treatment) and given a strong muscle relaxant. 3. A small amount of electric current (between 70 and 130 volts), lasting about half a second is passed through the brain. 4. The electric current produces convulsions – lasting up to one minute, which affect the entire brain. (The spasms are barely perceptible to onlookers.) 5. Repeated 3 times per week for up to 4 weeks 4. What is one one strength and one limitation of ECT (electro-convulsive therapy)? (2 + 2) Strength ECT can be an effective antidepressant treatment for patients unresponsive to other therapies (and especially when suicide is an issue). 60-70% of ECT patients improve after treatment (although a high percentage relapses within six months of treatment). Limitation ECT can have side effects. ECT can lead to long-term memory impairment, anxiety and headaches. 5. Outline techniques used in psychoanalysis. (4 or 6) The aim of psychoanalysis is to make “the unconscious conscious” – to uncover material repressed into the unconscious. Free association: • The client is encouraged to express anything that comes into their mind • Talking freely allows ego defences to be lowered and repressed material accessed • The therapist intervenes on occasions – to encourage further reflection, or to make interpretations Dream analysis: • Dreams are the “royal road to the unconscious”. The therapist analyses and interprets the manifest content (the content as reported by the dreamer), in order to uncover the latent content (the actual meaning of the dream) • The therapist hopes to identify significant repressed conflicts and unconscious wishes (often sexual or aggressive) 6. What is one strength and one limitation of psychoanalysis? (2 + 2) Strength Many therapies, for both children and adults, have been influenced by psychoanalysis, and its emphasis on the importance of childhood experiences and the unconscious. Limitation Psychoanalysis is usually very long lasting (months or years) and is expensive, therefore is not accessible for many social groups (e.g. the low-paid, unemployed). 7. Describe the use of systematic desensitisation in treating abnormality. (4 or 6) In the case of a phobia: 1. The therapist teaches the client deep relaxation techniques. 2. The therapist and client construct a desensitisation hierarchy – a series of imagined scenes, each one causing a little more anxiety that the previous one. 3. The therapist asks the client to visualise the least feared situation. Simultaneously the client performs the deep relaxation procedure. 4. Once the client feels comfortable at that level, they are asked to imagine the next situation in the hierarchy. The same procedure is repeated. 5. Over a series of sessions, the client will cope with every level of the hierarchy. 18 Individual Differences 8. What is one strength and one limitation of systematic desensitisation? (2 + 2) Strength Systematic desensitisation can be extremely effective in the treatment of simple phobias. Success rates of between 60 and 90% have been reported for spider phobics and injection phobics. Limitation Like all behavioural therapies, systematic desensitisation focuses on symptoms (that is, the phobic response) rather than any deeper underlying causes (why has the phobia developed?). 9. Outline what is involved in Cognitive Behavioural Therapy. (4 or 6) CBT assumes that problems in thinking underlie psychological disorders. The aim of Beck’s therapy is to challenge irrational and dysfunctional thought processes (about the self, the world and the future), and to replace them with more realistic and optimistic ones: 1. The therapist helps the client identify negative thoughts, e.g. “No one finds me attractive and they never will.” 2. The therapist challenges the dysfunctional cognitions by drawing attention to positive examples that contradict the client’s negative assumptions – this is referred to as reality testing. 3. The therapist uses behavioural techniques to encourage more positive thinking. The client may be set a list of small goals to be achieved – e.g. to ask someone to meet for coffee or a drink during the next week. These achievements increase the client’s self-efficacy. 10. What is one strength and one limitation of Cognitive Behavioural Therapy? (2 + 2)? Strength Courses of CBT are generally limited to a number of sessions over a few weeks. It is therefore less time consuming and more cost effective than psychoanalytic therapies. Limitation CBT is not suitable for all conditions, e.g. schizophrenia, and CBT is less effective than behavioural therapies for treating phobias. 11. Some patients, especially children and those with mental impairments, may not be able to give informed consent for treatment of their mental disorders. Explain how informed consent could be gained in an ethical manner for these types of patients. (4) Consult with a family member or recent provider of care, who could appreciate the potential reactions of clients, and help decide what is in their best interests. If the above is not possible, specific approval should be obtained from an appropriate institutional ethical committee. 19 Individual Differences Application of knowledge: Thinking on the spot! For some questions you need to apply your knowledge and understanding of psychology to a novel situation – what I term the “Thinking on the spot!” questions. You can’t predict these questions but you can develop your ability to answer them. The most important point to remember is: It is essential that you explicitly relate your knowledge to the situation or person described in the question. The two areas where it is most likely you would get a question asking you to apply your knowledge to a novel situation are definitions of abnormality and treatments. The following examples might help. The answers are longer than you would have time for in the exam – but hopefully give you ideas of how you might tackle the questions. DEFINITIONS OF ABNORMALITY 1. Daisy is a middle aged unemployed woman who lives in a large city. When she is out she can often be heard talking loudly to herself, sometimes repeating the same thing over and over again (e.g. “I can’t find my treasures.”) Sometimes people approach her and offer help but she carries on talking. When she is on a bus people often move to avoid being too close. (a) Identify two definitions of abnormality. (2) (b) Use the definitions identified above to explain why Daisy’s behaviour might be viewed as abnormal. (2) (a) Deviation from social norms and the failure to function adequately. (b) (i) According to the deviation of social norms definition, behaviour that goes against the implicit and explicit norms of society is considered abnormal. Daisy’s behaviour, talking loudly to herself, goes against the (implicit) social norm of not talking to oneself in public places, and would be considered abnormal. (Many people talk to themselves when alone, of course), (ii) According to the failure to function adequately definition, there are seven indicators of abnormality (as identified by Rosenhan and Selgiman) including observer discomfort, and maladaptive behaviour. Daisy’s behaviour would probably make many people feel uncomfortable. It would also be considered maladaptive/dysfunctional. 2. Sam becomes verbally aggressive with the least provocation and loses his temper on most days – usually because he thinks people are trying to get at him. He raises his voice and threatens strangers in supermarkets and when he uses public transport. He has lost three jobs in the last six months because he is sometimes abusive to his boss and other employees although he is very skilled at car mechanics. Explain Sam’s behaviour in terms of the following definitions of abnormality a. Deviation from social norms b. Failure to function adequately c. Deviation from ideal mental health a. Deviation from social norms- according to this definition, behaviour that goes against the implicit and explicit norms of society is considered abnormal. Sam’s hostility to strangers and his displays of verbal aggression at work are both contrary to implicit and explicit norms about how someone should behave in public. b. Failure to function adequately – according to this definition, there are seven indicators of abnormality, (as identified by Rosenman and Selgiman) including unpredictable and irrational behaviour. Sam’s behaviour is clearly unpredictable and irrational. (It is also maladaptive.) c. Deviation from ideal mental health – according to this definition, abnormality is the absence of certain criteria identified by Jahoda, including environmental mastery – how well-adapted a person is. Sam’s behaviour is not adaptive – he has difficulties in interpersonal relations. He also shows signs of a distorted perception of reality, e.g. he thinks people are getting at him. 20 Individual Differences TREATMENTS A question on treatments may ask you to apply your knowledge and understanding of a treatment to a novel person or situation. One strategy is to list the stages or features of a treatment and then provide examples from the scenario. It is essential that you relate your answer to the scenario. SYSTEMATIC DESENSITISATION Anna avoids eating in front of anyone except at home with family members. She becomes intensely anxious even at the thought of it. This means she can’t go out with her friends for a bite to eat, or accept invitations to have tea in their houses. Anna attends a sixth form college and it is quite difficult to find an empty room to eat her packed lunch. Often she skips meals. In order to overcome her fear, Anna sees a behavioural psychologist who feels that she may benefit from systematic desensitisation. Explain how a therapist might use systematic desensitisation to help Anna overcome her fear. (6) 1. The therapist would teach Anna deep relaxation techniques. 2. The therapist and Anna would construct a desensitisation hierarchy – a series of imagined scenes, each one causing a little more anxiety that the previous one. For example, the first scene could be a photograph of people eating in a restaurant. The final stage might be Anna imagining eating in the sixth form canteen. 3. The therapist would ask Anna to visualise the least feared situation (the photo of the restaurant) while simultaneously performing the deep relaxation procedure. 4. Once Anna feels comfortable, she would imagine the next situation in the hierarchy. (for example, eating in the same room as another person, but some distance away.) 5. Over a series of sessions, Anna will learn to cope with every level of the hierarchy. COGNITIVE BEHAVIOUR THERAPY/ DRUG THERAPY Miriam had been one of the best actors in her year when she studied performance arts. She often had the lead roles in the end of year plays. Recently however she has dreaded auditions and on three occasions has told her agent she doesn’t want the part. Before her last audition, she didn’t sleep the night before and she couldn’t stop her hands’ trembling. (a) Outline how drugs could be used to treat Miriam. (4) Beta-blockers could help Miriam because they tackle the physiological effects of stress, such as trembling hands. They do not enter the brain but reduce activity of the sympathetic nervous system in pathways around the body and block receptors on the heart which are stimulated by noradrenaline, and do not have side effects. Betablockers have been found to be effective for performance anxiety, e.g. musicians and certain snooker players, so might be appropriate for Miriam. (b) Outline how CBT would be used to treat Miriam. (4, 6)) The aim of CBT would be to challenge Miriam’s irrational and dysfunctional thought processes, and to replace them with more realistic and optimistic ones. 1. The therapist would help Miriam to identify negative thoughts – “I won’t be able to say the lines properly.” “I’ll never get another part.” 2. The therapist would challenge Miriam’s dysfunctional cognitions, by drawing attention to positive examples that contradict her negative assumptions – this is referred to as reality testing. “Why do you think you got all those parts while at college?” “What kind of reviews did you get?” “When did you forget your lines?” 3. The therapist may use behavioural techniques to encourage more positive behaviour. Miriam would be set a list of small goals to be achieved, e.g. reading a part in front of a close friend or phoning her agent. These achievements will increase Miriam’s self-efficacy. 21 Individual Differences PSYCHOANALYSIS Yanuk has become more and more withdrawn since starting university. He stays in his room a lot of the time, and has stopped going to lectures. He sometimes talks to his flat mates in the communal kitchen but doesn’t join them when they go out. He thinks he is on the wrong course and wants to leave university at the end of term but feels he would be letting his parents down. Yanuk has been referred to a therapist for psychoanalysis. Outline how psychoanalysis might be used to treat Yanuk. (6) The aim of psychoanalysis would be to help Yanuk uncover unconscious reasons for why he is finding university so difficult. Techniques include free association and dream analysis. Free association: • Yanuk would be encouraged to express anything that comes into his mind, no matter how trivial. • Talking freely allows ego defences to be lowered and repressed material accessed. e.g. Yanuk might remember times when he was dropped off and left by himself in the playground when he was in nursery and felt frightened. • The therapist intervenes on occasions – to encourage further reflection, or to make interpretations, e.g. Yanuk’s fears of separation. Dream analysis: Dreams are the “royal road to the unconscious”. The therapist would encourage Yanuk to recall his dreams. The therapist seeks to identify themes that emerge from these, for example, being abandoned or fear of his parents dying. 22
