Psychology Approaches and Methods in Psychology Introductory Student Guide [HIGHER] STUDENT GUIDE Introduction to the unit What this unit is about This unit is designed to introduce you to different approaches to the study of human behaviour, different research methods for studying human behaviour and the different types of research design used in psychology. You will learn about the aims, applications and limitations of each approach, the advantages and disadvantages of each research method and the relative merits of each experimental design. Outcomes On completion of this unit you will be able to: • explain the main theoretical approaches to psychology • compare the main research methods used in psychology • explain experimental research design in psychology. Prior experience Access is at the discretion of the centre. However, you will normally be recommended to have attained the following: • Standard Grade English at credit level/Intermediate 2 Level English or Communication 3 Progression and related study On successful completion of the Approaches and Methods in Psychology unit – D405 12 – 1 credit (40 hours), you may wish to progress to the Cognitive Psychology unit – D400 12 – 1 credit (40 hours) then onto the Social Psychology unit – D401 12 – 1 credit (40 hours), successful completion of which will allow you to prepare for and progress to the external assessment for the SQA Psychology (Higher). APPROACHES AND METHODS IN PSYCHOLOGY (H) 3 INTRODUCTORY STUDENT GUIDE Core skills Core skills are the transferable skills needed for life and for lifelong learning. They are not new and learning them doesn’t begin with National Qualifications. They have been a recognised part of school/ college learning for some time. National Qualifications will build on and develop the good work you’ve already done in school or college. The core skills in National Qualifications are: • Communication • Numeracy • Problem Solving (made up of critical thinking, planning and organising, and reviewing and evaluating) • Information Technology • Working with Others. Employers, colleges and universities increasingly give weight to the importance of core skills. Through National Qualifications, students will be able to develop core skills through a wide range of subjects in the curriculum, learn how to transfer them and to apply them in new situations. Your tutor will keep you informed of how core skills are incorporated into the unit/course you are currently studying. 4 APPROACHES AND METHODS IN PSYCHOLOGY (H) INTRODUCTORY STUDENT GUIDE Open learning pack structure No matter which open learning study section you are following, your self study materials will be made up of the same component parts.

Whether you’re new to open learning or not, the first step towards being a successful open learner is to be familiar and comfortable with the learning materials. It’s well worth spending a little of your initial study time scanning the study sections to see how they’re structured, what the various features are called and what they’re designed to do. This will save you a lot of time and frustration when you start studying, as you’ll then be able to concentrate on the actual subject matter itself without the need to refer back to what you’re supposed to be doing with each part. Course study sections Each study section of your open learning pack is structured in exactly the same way: • Contents page • An introduction to the section – what the section is about – the objectives of the section – suggested study time for the section – other resources required which are not included in the pack • Assessment information – how, when, where, what assessment for the section will take place • Subject content, including – Activities (A), Self Assessed Questions (SAQ), Tutor Assignments (TA) – Feedback to SAQs (at the back of the study section and before the Tutor Assignment) – Comments on activities (immediately follow the activity) – Advice on the return of Tutor Assignments, where appropriate • Summary – designed to reinforce what has just been done and generally provides a quick reference to the contents of the section 8 APPROACHES AND METHODS IN PSYCHOLOGY (H) INTRODUCTORY STUDENT GUIDE Approximate study time While the time allocated to this unit is at the discretion of the centre, the notional design length is 40 hours. The study times quoted on pages 6 and 7 should therefore be used as a guide only. APPROACHES AND METHODS IN PSYCHOLOGY (H) 9 INTRODUCTORY STUDENT GUIDE Symbols used in the pack This open learning pack allows you to work on your own with tutor support. As you work through the course, you’ll encounter a series of symbols which indicate that something follows which you’re expected to do. You’ll notice that you are asked to work through the study sections by undertaking a series of Self Assessed Questions, Activities and Tutor Assignments. An explanation of these symbols is given below. Self Assessed Questions ? This symbol is used to indicate a Self Assessed Question (SAQ). Most commonly SAQs are used to check your understanding of the material that has already been covered in the sections. This type of assessment is self contained, that is everything is provided within the section to enable you to check your understanding of the materials. The process is simple: • You are set SAQs throughout the study section. These will be set as short answer questions, true/false questions, multiple choice questions and definitions of psychological terms. • You respond to these, either by writing in the space provided in the assessment itself, or in your own notebook. • On completion of the SAQ, you turn to the back of the section to compare the SAQ responses to yours. • If you’re not satisfied after checking out your responses, turn to the appropriate part of the study section and go over the topic again. Remember that the answers to SAQs are contained within the study materials. You’re not expected to ‘guess’ at these answers. 10 APPROACHES AND METHODS IN PSYCHOLOGY (H) INTRODUCTORY STUDENT GUIDE Activities A This symbol indicates an activity which is normally a task that you’ll be asked to do to improve or consolidate your understanding of the subject in general or a particular feature of it. You’ll be asked to read a passage and answer questions, revise a topic already covered, complete sentences, relate your own experiences to psychological approaches and carry out simple experiments. The suggested responses to activities will follow directly after the activity. Remember that the SAQs and activities contained within your pack are intended to allow you to check your understanding and monitor your own progress throughout the course. It goes without saying then, that the answers to these should only be checked out after the SAQ or activity has been completed. If you refer to these answers before completing the activities you can’t expect to get maximum benefit from your course. Tutor Assignment T This symbol means that a Tutor Assignment is to follow. These will be found at the end of each study section. The aim of the Tutor Assignment is to cover and/or incorporate the main topics of the section and prepare you for unit (summative) outcome assessment. APPROACHES AND METHODS IN PSYCHOLOGY (H) 11 INTRODUCTORY STUDENT GUIDE Assessment information Doing well in any assessment involves: • being clear about how you will be assessed • knowing when your learning will be assessed • as an open learning student, knowing where learning will be assessed. How you will be assessed Throughout each study section of the open learning pack, a series of Self Assessed Questions (SAQs) and activities have been developed to provide you with ‘on the spot’ feedback in terms of your progress within the relevant section. If you haven’t arrived at the correct responses to SAQs and activities, you should return to the relevant areas for further study, before progressing within the section. Upon successful completion of all SAQs and activities, you’ll be asked to attempt a Tutor Assignment (TA). Each section usually finishes with a TA and each assignment has been devised as a means of assessing your progress on the knowledge and understanding required for your SQA unit. Generally, the requirements of the TAs closely match the outcomes of the unit. If you’re in any doubt about the completion of TAs or any aspect of assessment, you should contact your tutor for help. When and where you will be assessed When you feel you are thoroughly familiar with the learning materials, have worked through the SAQs, activities and TAs, you will undertake unit (summative) assessments. These unit assessments will be set and marked by your tutor. Unit assessments may be undertaken at the centre, or at a distance from the centre, under supervision. The results of unit assessments are recorded by your tutor and form the basis of your final results within this unit. Your tutor will organise all the necessary paperwork and inform you of your successful completion of the unit. Your tutor will help you decide whether or not you are fully prepared for your assessment and what procedures should be followed. 12 APPROACHES AND METHODS IN PSYCHOLOGY (H) INTRODUCTORY STUDENT GUIDE What you have to achieve All outcomes have to be assessed and the objective of this 40-hour unit is that you will achieve outcomes 1,2 and 3 of SQA Unit D405 12 – Approaches and Methods in Psychology. Types of assessment used for this course will be a written examination paper and completion of a psychological investigation and report. Opportunities for reassessment If you don’t achieve the required standard for the award of ‘pass’ within any assessment you’ll be informed of this and arrangements will be made for you to be reassessed on the particular elements of the assessment which need improving. External assessment You’ll need to pass the unit assessments for all the units in the Higher course if you wish to gain a Higher course award. You must also undertake an external assessment, where your work is assessed by examiners independently, outwith centre unit assessments. This external assessment will be set nationally by the Scottish Qualifications Authority, the body which is responsible for all assessment in Scotland. Part of the external assessment for the course is an examination and part is an investigation and a research report which is submitted to SQA for marking. Extra time is allowed within each Higher course to allow you to prepare fully for external assessment in addition to the time allowed to complete the units of your course. The type of assessment to be used for this course will be a written examination paper and completion of a psychological investigation and report. Courses will be graded A, B or C passes. Your tutor will keep you fully informed of the external assessment arrangements for the course you are studying.

APPROACHES AND METHODS IN PSYCHOLOGY (H) 15 INTRODUCTORY STUDENT GUIDE Glossary of terms – Section 2 Behaviourism One of the approaches in psychology. It is based on conditioning. It takes the view that only observable behaviour is appropriate for scientific study and that internal mental process cannot be studied in this way. Classical conditioning Learning that results from the association of two stimuli. Also referred to as Pavlovian conditioning or respondent behaviour. Discrimination The ability to perceive differences between two or more stimuli. Extinction The gradual disappearance of a learned response. Generalisation Once a conditioned response has been established, similar stimuli will also lead to the same conditional response. Learning A relatively permanent change in behaviour, caused by reorganising existing habits and skills. It is not change simply as a result of growth or deprivation. Negative reinforcement Removal of an aversive stimulus, escape. Neutral stimulus (NS) In classical conditioning, it is any stimulus that does not naturally produce the unconditional response. In operant conditioning, it is any stimulus which has no effect upon behaviour. Operant conditioning Learning that happens when an organism associates its own behaviour with the results of that behaviour. Also referred to as instrumental conditioning. Punishment A procedure which uses aversive stimuli in order to decrease the probability of a response. 16 APPROACHES AND METHODS IN PSYCHOLOGY (H) INTRODUCTORY STUDENT GUIDE Reflex An involuntary response which is unlearned and important for survival. Examples include: blinking, fear, salivation. Reinforcement A stimulus which strengthens learning. Both positive and negative reinforcement increases the probability of a response occurring. Reinforcer Any event or behaviour which acts as reinforcement. Response Any action originating from the organism, including movements, thoughts or glandular secretions. Reward Something which increases the probability of the response occurring. The same as positive reinforcement. Shaping Learning something through the use of progressive reinforcement. Reinforcement firstly is given for behaviours that resemble the desired response. Gradually reinforcement is only given for behaviours that are more specific and increasingly similar to the desired response. Stimulus Anything that affects the organism so that behaviour is changed in some detectable way. Unconditioned response (UCR) An unlearned response. Unconditioned stimulus (UCS) Stimulus that elicits an unlearned response. APPROACHES AND METHODS IN PSYCHOLOGY (H) 17 INTRODUCTORY STUDENT GUIDE Glossary of terms – Section 3 Attention The process by which we focus and concentrate on a selection of information rather than all the information bombarding our senses. Cognitive style The difference between individuals in terms of the cognitive approaches they tend to use, e.g. convergent/divergent thinking. Concept The mental representation of a group of things that share the same attribute(s). Convergent thinking Producing one correct solution to a problem by bringing information together, like deductive reasoning. Divergent thinking Creating one or more novel and unusual solutions to a problem. The solutions must be appropriate and valuable. Sometimes also called creativity or lateral thought. Intelligence The ability to learn from experience, think in abstract terms and deal effectively with our environment. Language A set of symbols which are used to convey ideas to others. Memory The mental function of retaining data, the storage system which holds the data, and the data which is retained. Mental imagery Mental pictures used to aid memory. Perception A system of detection which uses our senses to transmit information from the outside world to the higher senses of the brain. Here it is recognised, interpreted and integrated with existing information. Schema A structured cluster of concepts based on experience and used to generate future expectations. 18 APPROACHES AND METHODS IN PSYCHOLOGY (H) INTRODUCTORY STUDENT GUIDE Glossary of terms – Section 4 Anal stage The second psychosexual stage of development in which children derive pleasure from their faeces. Castration anxiety The anxiety experienced by a young boy during the Oedipus complex. The fear of being castrated by his father as a punishment for his feelings towards his mother. Conscience The part of the superego that is the source of feelings of guilt. Displacement A defence mechanism. Anxiety is displaced by blaming someone else for something we have done. Dream analysis The interpretation of symbols in dreams as revealing what the person really wants. Ego The part of the personality structure that deals with external reality and controls the energies of the id. Ego ideal The part of the superego that is the source of feelings of pride. Fixation A lingering attachment to an early stage of pleasure seeking. Free association A technique to explore a person’s unconscious. The person is encouraged to talk freely and say the first thing that comes into his head. Genital stage The fifth psychosexual stage of development in which pleasure derives from mature genital contact. Id The primitive part of the unconscious personality which is responsible for extreme emotional reactions and demands for immediate satisfaction. APPROACHES AND METHODS IN PSYCHOLOGY (H) 19 INTRODUCTORY STUDENT GUIDE Identification The process whereby children take on the characteristics of the same sex parent. Latency stage The fourth psychosexual stage of development during which the libido is ‘dormant’. Libido The energy of the sexual instinct. Morality principle The superego’s insistence that the ego does not use unacceptable ways to satisfy the id’s demand. Oral stage The first psychosexual stage of development in which children derive pleasure from their mouths. Phallic stage The third psychosexual stage of development, in which interest is focused on the genitals. The stage of development which involves the Oedipal conflict. Pleasure principle The id’s demands for the immediate satisfaction of its instinctual urges. Psyche The principles of emotional and mental life. Rationalising A defence mechanism. The justification of one’s action to reduce anxiety. Reality principle The ego’s insistence that the id’s demands are satisfied in a realistic way. Repression A defence mechanism. Pushing unpleasant thoughts into the unconscious to reduce anxiety. 20 APPROACHES AND METHODS IN PSYCHOLOGY (H) INTRODUCTORY STUDENT GUIDE Slips of the tongue Errors of speech in which we unintentionally say what we really mean. Superego The third part of the personality which is concerned with morality and conscience. It operates according to the morality principle. Unconscious A reference to mental activity that is not available to consciousness because it concerns material which is too threatening or upsetting. Glossary of terms – Section 5 ANS The autonomic nervous system controls our internal bodily functions. The ANS regulates our internal bodily environment by sending information to our central nervous system, or brain and spinal cord, which makes any necessary internal adjustments. The ANS is subdivided into two branches, the sympathetic branch, and the parasympathetic branch. The sympathetic branch of our ANS moves us to action in our world. What this means is that the sympathetic branch of the ANS operates when we have to use, or expend, energy. The parasympathetic branch of our ANS operates when we have to restore this expended energy to our body. The sympathetic and parasympathetic branches of our autonomic nervous system are thus said to be antagonistic to each other. As one branch of the ANS pulls in one direction, the other branch pulls in the other direction. This is to return our body to our natural state of homeostasis, or internal balance. Bilateral A function is equally represented by both sides of the brain. Brain stem The general area which connects the spinal column to the higher brain. Cerebellum An area of the brain which is situated behind the medulla and which coordinates voluntary movement, muscle tone and body balance. Cerebral dominance The side of the brain which has greater control over a particular function. Also called hemispheric dominance. APPROACHES AND METHODS IN PSYCHOLOGY (H) 21 INTRODUCTORY STUDENT GUIDE Contralateral One hemisphere controls the opposite side of the body. Cortex The outermost layer of grey matter in the forebrain which controls higher cognitive and intellectual behaviour. Endocrine system The system of glands which produce hormones. Frontal lobe The largest part at the front of the brain. Hemisphere One half of a sphere. The brain is separated into two hemispheres, left and right. Hippocampus Located between the thalamus and the cortex, it is an area of the brain which is involved in learning and storing new information in memory. Hypothalamus An area of the brain situated below the thalamus. It integrates the activity of an ANS. It is the cognitive centre for emotions, stress, motivation and homeostasis. Limbic system An area of the brain which includes parts of the cortex and hypothalamus. It is important in emotion and motivation. Localisation Particular areas of the cerebral cortex are associated with specific physical or behavioural functions. Medulla Area of the brain which is situated at the base of the brain stem. It is the centre which controls heartbeat, breathing, swallowing, blood pressure, digestion, etc. Occipital lobe An area at the back of the brain which includes the visual cortex. 22 APPROACHES AND METHODS IN PSYCHOLOGY (H) INTRODUCTORY STUDENT GUIDE Parietal lobe A brain area between the frontal and the occipital. Pituitary gland An endocrine gland located in the brain. It is attached to the base of the hypothalamus. It controls hormonal secretions and other ANS glands. Reticular activating system (RAS) An area found in the core of the brain stem. It is related to sleep, arousal, consciousness and attention. Temporal lobe An area of the brain which is situated on the side, below the occipital lobe. It contains the auditory cortex for hearing and balance. It also contributes to memory, language, emotion and perception. Thalamus An area of the brain which lies under the corpus callosum. It receives sensory data, performs some processing and passes the data on to the cerebral cortex. Glossary of terms – Section 6 Basic needs The most compelling human needs such as food and the avoidance of pain. In Maslow’s theory these are at the base of a hierarchy of needs and other requirements, even for physical safety, will be ignored until they are satisfied. Client-centred therapy A form of psychotherapy developed by Carl Rogers, based on a humanistic approach, in which the individual is considered to be the only person who can develop solutions or approaches to their problem. The role of the therapist is to facilitate such development. Empirical Such as can be measured. Empirical observations are those that can provide a level of objective data, which can be assessed in one form or another. Hierarchy A structured form of organisation constructed in levels, with each level overshadowing or dominating the lower ones. APPROACHES AND METHODS IN PSYCHOLOGY (H) 23 INTRODUCTORY STUDENT GUIDE Humanistic psychology An approach within psychology which emphasises the whole person and their scope for change. Personality Those relatively enduring features which account for a person’s characteristic way of behaving. Some uses of the term ‘personality’ refer to patterns of behaviour rather than their causes. Some theories are concerned with the way the structures underlying personality are formed, i.e. Freud. Other theories try to find a biological basis for personality, i.e. Eysenck’s theory of types, while still others measure different aspects of people, i.e. Cattel’s traits. Glossary of terms – Section 7 Bias A prejudice, a leaning in one direction only. Biased sampling Some participants are more or less likely to be selected than they should be, given their frequency in the population. This leads to systematic errors in the data. Control group The participants who receive no treatment and act as a comparison with the experimental group for control purposes. Counterbalancing An experimental procedure for controlling irrelevant factors, especially order effects. Dependent variable The variable we look at to see if there are any changes produced by our manipulation of the causal variable. It is the variable we measure. Experimental group The group of participants who receive the experimental treatment. Experimenter effect An experimenter has expectations about the outcome of an experiment and may indirectly and unconsciously communicate these to the participant. This affects the participant’s behaviour. 24 APPROACHES AND METHODS IN PSYCHOLOGY (H) INTRODUCTORY STUDENT GUIDE Field experiment An experimental manipulation of an independent variable that takes place in a natural setting rather than in the more artificial setting of the laboratory. Hypothesis A formal, unambiguous statement of what you predict. The research will either prove or disprove this prediction. Independent measures Comparison is made between two unrelated groups of participants. The participants are in groups not pairs. One group receives the experimental treatment, the other doesn’t. Their performance on the dependent variable is compared. Independent variable The variable we suspect is the causal variable. Laboratory experiment An investigation where the experimental manipulation of the independent variables takes place within such conditions that careful control of variables is possible. Natural experiment An investigation where the allocation of participants to the different experimental conditions is outside the control of the investigator, and is manipulated by some outside agency. Opportunity sampling Selecting participants because they are available. Order effects When participants are tested on two (or more) conditions (A and B) their performance may be improved or depressed by certain factors such as practice, fatigue or boredom. Population Total number of cases about which a specific statement can be made (sometimes called the target population). Quota sampling The population is divided into sections or strata. A fixed number of samples are taken from each section. Also called stratified sampling. APPROACHES AND METHODS IN PSYCHOLOGY (H) 25 INTRODUCTORY STUDENT GUIDE Random sampling Every member of the population has an equal chance of being selected, therefore it is an unbiased sample. Can be achieved with random number tables or numbers drawn from a hat. Research An attempt to study a problem systematically. Research design The overall plan of action to maximise meaningful results and minimise ambiguity using research techniques. Control is an important feature of design. Research method A way of doing things in a systematic manner. Sample Part of a population selected such that it is considered to be representative of the population as a whole. Scientific method A series of procedures which produce an objective body of facts. Variable Something/anything that varies in a given situation. Volunteer sampling Participants who become part of an experiment because they volunteer when asked. This is not random. 26 APPROACHES AND METHODS IN PSYCHOLOGY (H) INTRODUCTORY STUDENT GUIDE Before moving on to the study sections, you may want to check your general understanding of the open learning materials for your unit.

APPROACHES AND METHODS IN PSYCHOLOGY (H) 39 TUTOR GUIDE Introduction to this pack This open learning pack covers the syllabus requirements for the SQA National Unit, Approaches and Methods in Psychology, at Higher Level. The pack consists of an Introductory Guide and eight study sections as indicated below. Introductory Guide Pages: 3–30 Study Time: 1 hour Section 1 A Look at Psychology Pages: 83–106 Study Time: 2 hours Section 2 The Behaviourist Approach Pages: 107–144 Study Time: 5 hours Section 3 The Cognitive Approach Pages: 145–186 Study Time: 5 hours Section 4 The Psychoanalytic Approach Pages: 187–230 Study Time: 5 hours Section 5 The Biological Approach Pages: 231–276 Study Time: 5 hours Section 6 The Humanistic Approach Pages: 277–312 Study Time: 4 hours 40 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Section 7 Research Using Experiments Pages: 313–386 Study Time: 6 hours Section 8 Research Using Non-experimental Methods Pages: 387–431 Study Time: 4 hours Course study sections • Each study section of this open learning pack is structured in exactly the same way: • Contents page • An introduction to the section – what the section is about – the objectives of the section – suggested study time for the section – other resources required which are not included in the pack • Assessment information – how, when, where, what assessment for the section will take place • Subject content, including – Activities (A), Self Assessed Questions (SAQ), Tutor Assignments (TA) – Feedback to SAQs (at the back of the study section and before the Tutor Assignment) – Comments on Activities (immediately follow the Activity) – Advice on the return of Tutor Assignment, where appropriate • Summary – designed to reinforce what has just been done and generally provides a quick reference to the contents of the section Approximate study time While the time allocated to this unit is at the discretion of the centre, the notional design length is 40 hours? The study times quoted on pages 40 and 41 should therefore be used as a guide only. APPROACHES AND METHODS IN PSYCHOLOGY (H) 41 TUTOR GUIDE Symbols used in the pack This open learning pack has been designed to meet the outcomes of the SQA Unit ‘Approaches and Methods in Psychology’. There are eight distinct study sections, each relating to an outcome of the unit. The study sections allow students to work on their own with your support. As they work through the sections, they will encounter a series of symbols indicating that something follows which they are expected to do. An explanation of these symbols is given below. Self Assessed Questions ? This symbol is used to indicate a Self Assessed Question (SAQ). Most commonly SAQs are used to check the students’ understanding of the material that has already been covered in the sections. This type of assessment is self contained, that is everything is provided within the section to enable students to check their understanding of the materials. This process is simple: • The students are set SAQs throughout the study section. These will be set as short answer questions, true/false questions, multiple choice questions and definitions of psychological terms. • They respond to these, either by writing in the space provided in the assessment itself, or in their own notebook. • On completion of the SAQ, they turn to the back of the section to compare the SAQ responses to theirs. • If they are not satisfied after checking out their responses, they should turn to the appropriate part of the study section and go over the topic again. Remember that the answers to SAQs are contained within study materials. Students are not expected to ‘guess’ at these answers. 42 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Activities A This symbol indicates an activity which is normally a task the student will be asked to do which should improve or consolidate understanding of the subject in general or a particular feature of it. Students will be asked to read a passage and answer questions, revise a topic already covered, complete sentences, relate their own experiences to psychological approaches and carry out simple experiments. The suggested responses to activities will follow directly after the activity. Remember that SAQs and activities contained within the pack are intended to allow students to check their understanding and monitor their own progress throughout the course. It goes without saying then, that the answers to these should only be checked out after the SAQ or activity has been competed. Tutor Assignment T This symbol means that a Tutor Assignment is to follow. These are usually found at the end of each section. The aim of the Tutor Assignment is to cover and/or incorporate the main topics of the study section and prepare the student for unit (summative) outcome assessment. APPROACHES AND METHODS IN PSYCHOLOGY (H) 43 TUTOR GUIDE Assessment information How students will be assessed Throughout each study section of the open learning pack, a series of Self Assessed Questions (SAQs) and activities have been developed to provide the student with ‘on the spot’ feedback in terms of their progress within the relevant Section. Upon successful completion of all SAQs and activities, the student will be asked to attempt a Tutor Assignment (TA). Each section usually finishes with a TA and each assignment has been devised as a means of assessing students’ progress on the knowledge and understanding required for their SQA unit to date. Generally, the requirements of the TAs closely match the outcomes of the unit. When and where students will be assessed As a tutor, you should summatively assess each student after successful completion of the appropriate TA, using your own centre’s instrument(s) of summative assessment. All assessments will be conducted at the centre where appropriate. The summative assessments are recorded by you, the tutor, and form the basis of the student’s final results within the unit. The student has been informed that you will complete all the necessary paperwork and inform them of their successful completion of the unit. Depending on the policy of your open learning centre, summative assessment may be undertaken at the centre, or at a distance from the centre, under supervision. Most often assessment is undertaken by the learner at the centre under the supervision of a tutor. However, for the open learner who lives some distance from the centre, an invigilation system may be set up at a recognised support centre local to the student (community education centre, training centre, etc.). What students have to achieve All outcomes have to be assessed and the objective of this 40-hour unit is that the student will achieve Outcomes 1, 2 and 3 of SQA Unit D405 12 – Approaches and Methods in Psychology. 44 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Types of assessment used for the course in Psychology (Higher level) will be a written examination paper and completion of a psychological investigation and report. Opportunities for reassessment If the student doesn’t achieve the required standard for the award of ‘pass’ within any assessment, they should be informed of this and you should arrange for the student to be reassessed on the particular elements of the assessment which need improving. Alternative instruments of summative assessment should be available and utilised where necessary. External assessment To gain the Higher course award, the student must achieve all the component units of the course as well as the external assessment. The external assessment will provide the basis for grading attainment in the course award. When units are taken as component parts of a course, students will have the opportunity to demonstrate achievement beyond that required to attain each of the unit outcomes. This attainment may, where appropriate, be recorded and used to contribute towards course estimates and to provide evidence for appeals. Additional details are provided, where appropriate, within the exemplar assessment materials. Further information on the key principles of assessment are provided in the paper Assessment (HSDU, 1996) and in Managing Assessment (HSDU, 1998).

Submit this to your tutor for marking. 46 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Confidential Suggested responses to Tutor Assignment – Section 1 1. Psychology is the scientific study of the mind and behaviour. 2. The behaviourist approach studies only what can be directly observed – behaviour, whereas in the psychoanalytic approach the focus is on stimuli which trigger behaviour. 3. Psychologists gather psychological knowledge in a systematic way, carrying out research. 4. The ‘scientific method’ refers to producing evidence, through studies, which can be verified. 5. The cognitive approach fell into decline at that time because the method used to investigate mental processes was not objective. 6. The biological approach focuses on how the physical systems of the body influence both our mental processes and behaviour, whereas the humanist approach focuses on the individual and the motivation for personal fulfilment. APPROACHES AND METHODS IN PSYCHOLOGY (H) 47 TUTOR GUIDE Tutor Assignment – Section 2 T2 1. Explain the aim of the behaviourist approach. 2. What are the limitations of the behaviourist approach in accounting for human behaviour? 3. How is the behaviourist approach used by psychologists or other professionals when working with people? Give one example of this. Submit this to your tutor for marking. 48 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Confidential Suggested responses to Tutor Assignment – Section 2 Students should cover the main points. 1. The behaviourist approach aims to study the effects of the environment and learning on individual behaviour. • Classical conditioning refers to learning by association. Ivan Pavlov discovered that dogs salivated in response to a bell which had been associated with the presence of food. • Operant conditioning refers to learning by reinforcement. • Positive reinforcement increases behaviour through reward. • Negative reinforcement increases behaviour through the avoidance of something unpleasant or painful. • Punishment decreases behaviour in the short term by administering something unpleasant or painful. • Schedules of reinforcement are important in operant conditioning as it was established that reinforcement does not have to be given after each instance of behaviour. Variations in the time period in which reinforcement is given lead to the desired behaviours still being produced. 2. The limitations of the behaviourist approach are that: • not all behaviour can be explained by conditioning • it is deterministic and does not consider people as individuals with free will and the ability to control their own behaviours • findings from laboratory studies on animals may not explain human behaviour. 3. Students should explain clearly one of the following applications: Reinforcement in cocaine users – Mestel and Concar (1994) Aversion therapy – Weing and Menustik (1983) Systematic desensitisation Operant conditioning in pigeons – Simmons (1981) APPROACHES AND METHODS IN PSYCHOLOGY (H) 49 TUTOR GUIDE Tutor Assignment – Section 3 T3 Read this description and then answer the questions that follow: Two psychologists disagreed about who would behave best in school. The first psychologist said that the children who usually received a lot of praise from their teacher would behave best. The second psychologist said that those children who were always kept busy revising and thinking about how to solve things would behave best. 1. What psychological approach does: (a) the first (b) the second psychologist favour? 2. What is the aim of the cognitive approach? 3. What is the aim of the behaviourist approach? 4. In what sense is: (a) the cognitive approach (b) the behaviourist approach limited? 5. Give one example of the use of the cognitive approach. 6. How is the behaviourist approach used by psychologists or other professionals when working with people? Submit this to your tutor for marking. 50 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Confidential Suggested responses to Tutor Assignment – Section 3 1. (a) (b) 2. The cognitive approach aims to explain behaviour in terms of the internal mental or mediational processes we have. Mediational processes are • • • • • Behaviourist approach Cognitive approach memory which stores and retrieves information perception which organises information attention which selects and represents information language which represents information symbolically thinking which uses information to produce ideas. We take in information from our environment and the mind actively processes it in order to produce a response. In this way, cognitive psychologists see the mind as being like a computer. 3. It aims to explain that behaviour is conditioned. 4. (a) The cognitive approach is limited in that: • it does not account for the influence of emotion, family conditions or education on behaviour, i.e. it is not holistic • comparing the human mind to a computer leads to a view of human thinking as machine-like and mechanistic • the focus on laboratory investigation means that behaviour in such an artificial setting may not be representative of behaviour in real life situations. (b) The limitations of the behaviourist approach are that: • not all behaviour can be explained by conditioning • it is deterministic and does not consider people as individuals with free will and the ability to control their own behaviours APPROACHES AND METHODS IN PSYCHOLOGY (H) 51 TUTOR GUIDE • findings from laboratory studies on animals may not explain human behaviour. 5. One of the following applications should be explained clearly: • • • • 6. Visual illusions Eyewitness testimony – Elizabeth Loftus Selective attention – Eysenck (1984) Computer modelling Students should explain clearly one of the following applications: Reinforcement in cocaine users – Mestel and Concar (1994) Aversion therapy – Weing and Menustik (1983) Systematic desensitisation Operant conditioning in pigeons – Simmons (1981) 52 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Tutor Assignment – Section 4 T4 Read this description and then answer the questions that follow: A man who was said to be suffering from depression could not remember his name or the name of any of his family. During therapy, he said that he often dreamed about being a world-famous celebrity. At the next therapy session, he said he could remember his son’s name. His son’s name was Harry, but he distinctly said ‘Hates me’. 1. What psychological approach is being used to help this man? 2. What does the psychoanalytic approach aim to do? 3. Give two examples of how the psychoanalytic approach is used to help people. 4. What limitations do we associate with the psychoanalytic approach? Submit this to your tutor for marking. APPROACHES AND METHODS IN PSYCHOLOGY (H) 53 TUTOR GUIDE Confidential Suggested responses to Tutor Assignment – Section 4 1. Psychoanalytic approach. 2. Students should include the following aims: • Psychoanalysis aims to explain behaviour in terms of personality. According to Freud the personality is made up of the id (the unconscious part which demands instant gratification), the ego (the rational aspect of the personality) and the superego which operates as our ‘conscience’. The superego and the ego modify the pleasure-seeking id with the ego, keeping the balance between the superego and id. • When there is an imbalance between the three aspects of the personality, an individual will experience anxiety. Defence mechanisms are unconscious ways of reducing this anxiety. Some defence mechanisms are repression, displacement, regression and denial. 3. Two of the following applications should be explained accurately: Contemporary psychotherapy Cognitive therapy Play therapy 4. The limitations of the psychoanalytic approach are that: • it cannot be tested scientifically as there is no way to measure ‘instincts’ or ‘urges’ • again, the ‘unconscious’ is invisible so its existence can never be scientifically established • Freud’s theories were based on a biased sample so it is difficult to apply these generally • it is a pessimistic and deterministic approach with Freud’s emphasis on the nature of an individual’s development being fixed within the first five years of life. 54 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Tutor Assignment – Section 5 T5 Here is a description for you to read carefully. After you have done so, attempt the questions below. Joan, a 34-year-old mother of three, was diagnosed with Hodgkin’s disease. This is a form of cancer that attacks the immune system. Joan’s doctors were pessimistic about the outcome of her illness, but Joan insisted that she would beat her illness and soon be well again. Her doctors were so concerned at her refusal to acknowledge her illness that they asked a therapist to visit her. Joan was not willing to speak to the therapist but instead embarked on a determined programme to keep up her spirits. A large part of this plan involved viewing classic comedy films in her hospital room. Joan firmly believed that laughter was the best medicine of all and watched at least three such films a day, enjoying them fully. She said that they helped take her mind off the pain. In the end, Joan recovered fully. 1. Which psychological approach best explains Joan’s recovery? 2. What other psychological approach is relevant here? 3. How do the aims of the cognitive approach and the biological approach differ? 4. Explain two uses of the biological approach in health care. 5. Why is the biological approach limited? Give two reasons. Why? Why? Submit this to your tutor for marking. APPROACHES AND METHODS IN PSYCHOLOGY (H) 55 TUTOR GUIDE Confidential Suggested responses to Tutor Assignment – Section 5 1. Biological approach By watching comedy films and laughing Joan is using relaxation techniques. Relaxation reduces anxiety which enabled Joan to control her own pain. 2. The cognitive approach Cognitive techniques can be used to counteract the experience of pain. Thought processes can be developed and used whenever pain is present. Joan put into practice a programme of laughter which refocused her attention and helped her manage her pain. 3. The cognitive approach seeks to explain behaviour in terms of mental processes while the biological approach explains behaviour in terms of physiological processes. 4. Two of the following should be explained accurately: • • • • • • • 5. Understanding psychosomatic illness Identification of stressors – Seyle (1956) Relationship between stress and ill-health Biofeedback Imagery Relaxation techniques Cognitive techniques Two of the following should be explained: • it is reductionist, i.e. it reduces behaviour to a simple set of physiological activities which possibly do not account for higher mental processing self awareness • it cannot provide complete explanation for memory, emotion, stress, learning and so on • reducing individuals to genetics again does not give a complete picture of the complexity of an individual’s behaviour and does not allow for the influence of experience. 56 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Tutor Assignment – Section 6 T6 Here is a personal description provided by a client during therapy. Read it and then answer the questions that follow. ‘Being an adult hasn’t really changed anything about how I feel most of the time. When I went to college, I really wanted to study Drama but to please my father I took a business course. He said that I needed to study something so I could get a proper job. And now I’m stuck with this boring job which I hate! I need to discover for myself what I want. I don’t want to spend the rest of my life trying to please other people.’ 1. What psychological approach would be most helpful to use here? 2. Distinguish between humanistic and the psychoanalytic methods of therapy. 3. What does the humanistic approach aim to do? 4. Describe two uses of the humanistic approach. 5. Explain two limitations of the humanistic approach. Submit this to your tutor for marking. APPROACHES AND METHODS IN PSYCHOLOGY (H) 57 TUTOR GUIDE Confidential Suggested responses to Tutor Assignment – Section 6 1. Humanistic 2. Humanistic methods of therapy provide a warm, accepting atmosphere where people can raise their self esteem by recognising their own strengths and limitations. The aim of clientcentred therapy is to enable the clients to make decisions and take control of their own fate. Psychoanalytic methods of therapy focus on bringing repressed feelings and motives out of the unconscious and into our conscious awareness. Psychotherapy tries to help people understand the motives behind their behaviour and helps them deal with these strong emotions and desires more rationally and realistically. 3. The following points should be explained: • The humanistic approach focuses on the uniqueness of the individual. It aims to explain behaviour in terms of motivation and the fulfilment of different needs. • Maslow’s hierarchy of needs is an account of how individuals are motivated to act at any one particular time. According to the humanistic approach, people will always behave in a way which allows them to meet the needs in the hierarchy and ultimately achieve self-actualisation. • Deficiency motivation is the tendency to maintain a physical or psychological balance. Physiological, safety, social and esteem needs are deficiency motives. Growth motivation refers to the tendency to self-actualise, to aim to strive for personal growth and fulfilment. If this is not achieved people will feel restless and dissatisfied with life. 4. Students should accurately describe two of the following applications: • • • • 58 Client-centred counselling Social skills training Peer group assessment Assertiveness training APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE 5. Two of the following limitations should be explained: • • • • Lack of evidence that humans operate on hierarchical level Does not account for all behaviour Most people will never achieve self-actualisation Maslow’s theory is based on clinical experience so is reliant on individual experiences as data – data is therefore unscientific • Little empirical evidence for Maslow’s hierarchy of needs. APPROACHES AND METHODS IN PSYCHOLOGY (H) 59 TUTOR GUIDE Tutor Assignment – Section 7 T7 Read this description and then answer the questions that follow: A psychology lecturer wanted to find out if psychology students learn better when they study alone or when they study in groups. He obtained a sample by selecting students at random from the departmental list of all psychology students. He then gave these students some material to study – the students studied the material together in groups or when they were by themselves. All students were given a short assessment afterwards. The assessment tested how much they had learned from the materials they were given. Here are the results of the study: Subject no. 1 Test Scores Studied in group Studied alone 30% 40% 2 3 50% 20% 20% 70% 4 5 20% 60% 80% 70% 6 7 10% 40% 30% 50% 8 9 20% 60% 60% 10% 10 70% 50% Now answer the questions on the next page. 60 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE 1.

APPROACHES AND METHODS IN PSYCHOLOGY (H) 61 TUTOR GUIDE Confidential Suggested responses to Tutor Assignment – Section 7 1. The student should mention: • random sampling ensures that each student in the study had an equal chance of being selected • in this way the sample is unbiased. 2. Independent variable – study method, i.e. alone or with others. Dependent variable – how much students had learned (test scores). 3. Possibilities include: Experimental, two-tailed hypothesis Student’s learning will be affected by the presence of others. Null hypothesis Student’s learning will not be affected by the presence of others. Experimental, one-tailed hypothesis Students will learn more when studying alone than when studying in groups. Null hypothesis Students will not learn more when studying alone than when studying in groups. 4. Advantage – improved test scores would be due to studying method (the independent variable) and not subject variables. 5. (a) (b) 62 Main drawback – increased test scores could be due to practice/order effects. Can be overcome by counter-balancing, i.e. reversing the order of the conditions. APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE 6. Advantage – improved test scores due to study method rather than order/practice effects. 7. (a) (b) 8. Main drawback – improvements in scores may have been caused by subject variables. Can be overcome by random allocation of subjects to conditions. The student could choose either research design as long as the explanation justified that choice. APPROACHES AND METHODS IN PSYCHOLOGY (H) 63 TUTOR GUIDE Tutor Assignment – Section 8 T8 1.

Asking for information from a large sample including factual information and or beliefs/opinions. The data is then analysed. 2. Two advantages of surveys, e.g. two from • large number of people • relatively cheap/easy to do • information not usually obtainable Two disadvantages of survey, e.g. two from • low response rates are common • sample may be biased • people may lie to ‘please’/‘fool’ researcher 3. Detailed investigation of a group with information obtained from records, interviews and/or psychological tests used to get detailed information that otherwise was not available. 4. Advantages – unique situations, detailed information. Disadvantages – cannot generalise, often incomplete data. 5. Investigates behaviour in a non-intrusive way. Important to control for bias. 6. Advantages – useful for children/animal research and investigating specific types of behaviours. Disadvantages – e.g. ethical issues, controls, time consuming. 7. Asking questions of individuals which can be informal or structured. 8. Advantages – rich detailed information, not threatening, can be individualised. Disadvantages – difficult to generalise, desire to please interviewer so not realistic answers, difficult to analyse. 9. Aim is to examine extent to which two variables are related. May not establish why they are linked. APPROACHES AND METHODS IN PSYCHOLOGY (H) 65 TUTOR GUIDE 10. Advantages – obtain data for further research, useful where other research is not possible (ethical issues). Disadvantages – does not demonstrate cause and effect, may be affected by other factors (time of day), simple rather than complex relationships. 66 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Other recommended resources There is no specific textbook for this unit.

It is based on conditioning. It takes the view that only observable behaviour is appropriate for scientific study and that internal mental process cannot be studied in this way. Classical conditioning Learning that results from the association of two stimuli. Also referred to as Pavlovian conditioning or respondent behaviour. Discrimination The ability to perceive differences between two or more stimuli. Extinction The gradual disappearance of a learned response. Generalisation Once a conditioned response has been established, similar stimuli will also lead to the same conditional response. Learning A relatively permanent change in behaviour, caused by reorganising existing habits and skills. It is not change simply as a result of growth or deprivation. Negative reinforcement Removal of an aversive stimulus, escape. Neutral stimulus (NS) In classical conditioning, it is any stimulus that does not naturally produce the unconditional response. In operant conditioning, it is any stimulus which has no effect upon behaviour. Operant conditioning Learning that happens when an organism associates its own behaviour with the results of that behaviour. Also referred to as instrumental conditioning. APPROACHES AND METHODS IN PSYCHOLOGY (H) 69 TUTOR GUIDE Punishment A procedure which uses aversive stimuli in order to decrease the probability of a response. Reflex An involuntary response which is unlearned and important for survival. Examples include: blinking, fear, salivation. Reinforcement A stimulus which strengthens learning. Both positive and negative reinforcement increase the probability of a response occurring. Reinforcer Any event or behaviour which acts as reinforcement. Response Any action originating from the organism, including movements, thoughts or glandular secretions. Reward Something which increases the probability of the response occurring. The same as positive reinforcement. Shaping Learning something through the use of progressive reinforcement. Reinforcement firstly is given for behaviours that resemble the desired response. Gradually reinforcement is only given for behaviours that are more specific and increasingly similar to the desired response. Stimulus Anything that affects the organism so that behaviour is changed in some detectable way. Unconditioned response (UCR) An unlearned response. Unconditioned stimulus (UCS) Stimulus that elicits an unlearned response. 70 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Glossary of terms – Section 3 Attention The process by which we focus and concentrate on a selection of information rather than all the information bombarding our senses. Cognitive style The difference between individuals in terms of the cognitive approaches they tend to use, e.g. convergent/divergent thinking. Concept The mental representation of a group of things that share the same attribute(s). Convergent thinking Producing one correct solution to a problem by bringing information together, like deductive reasoning. Divergent thinking Creating one or more novel and unusual solutions to a problem. The solutions must be appropriate and valuable. Sometimes also called creativity or lateral thought. Intelligence The ability to learn from experience, think in abstract terms and deal effectively with our environment. Language A set of symbols which are used to convey ideas to others. Memory The mental function of retaining data, the storage system which holds the data, and the data which is retained. Mental imagery Mental pictures used to aid memory. Perception A system of detection which uses our senses to transmit information from the outside world to the higher senses of the brain. Here it is recognised, interpreted and integrated with existing information. Schema A structured cluster of concepts based on experience and used to generate future expectations. APPROACHES AND METHODS IN PSYCHOLOGY (H) 71 TUTOR GUIDE Glossary of terms – Section 4 Anal stage The second psychosexual stage of development in which children derive pleasure from their faeces. Castration anxiety The anxiety experienced by a young boy during the oedipus complex. The fear of being castrated by his father as a punishment for his feelings towards his mother. Conscience The part of the superego that is the source of feelings of guilt. Displacement A defence mechanism. Anxiety is displaced by blaming someone else for something we have done. Dream analysis The interpretation of symbols in dreams as revealing what the person really wants. Ego The part of the personality structure that deals with external reality and controls the energies of the id. Ego ideal The part of the superego that is the source of feelings of pride. Fixation A lingering attachment to an early stage of pleasure seeking. Free association A technique to explore a person’s unconscious. The person is encouraged to talk freely and says the first thing that comes into his head. Genital stage The fifth psychosexual stage of development in which pleasure derives from mature genital contact. Id The primitive part of the unconscious personality which is responsible for extreme emotional reactions and demands for immediate satisfaction. 72 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Identification The process whereby children take on the characteristics of the same sex parent. Latency stage The fourth psychosexual stage of development during which the libido is ‘dormant’. Libido The energy of the sexual instinct. Morality principle The superego’s insistence that the ego does not use unacceptable ways to satisfy the id’s demand. Oral stage The first psychosexual stage of development in which children derive pleasure from their mouths. Phallic stage The third psychosexual stage of development, in which interest is focused on the genitals. The stage of development which involves the oedipal conflict. Pleasure principle The id’s demands for the immediate satisfaction of its instinctual urges. Psyche The principles of emotional and mental life. Rationalising A defence mechanism. The justification of one’s action to reduce anxiety. Reality principle The ego’s insistence that the id’s demands are satisfied in a realistic way. Repression A defence mechanism. Pushing unpleasant thoughts into the unconscious to reduce anxiety. APPROACHES AND METHODS IN PSYCHOLOGY (H) 73 TUTOR GUIDE Slips of the tongue Errors of speech in which we unintentionally say what we really mean. Superego The third part of the personality which is concerned with morality and conscience. It operates according to the morality principle. Unconscious A reference to mental activity that is not available to consciousness because it concerns material which is too threatening or upsetting. Glossary of terms – Section 5 ANS The autonomic nervous system controls our internal bodily functions. The ANS regulates our internal bodily environment by sending information to our central nervous system, or brain and spinal cord, which makes any necessary internal adjustments. The ANS is subdivided into two branches, the sympathetic branch, and the parasympathetic branch. The sympathetic branch of our ANS moves us to action in our world. What this means is that the sympathetic branch of the ANS operates when we have to use, or expend, energy. The parasympathetic branch of our ANS operates when we have to restore this expended energy to our body. The sympathetic and parasympathetic branches of our autonomic nervous system are thus said to be antagonistic to each other. As one branch of the ANS pulls in one direction, the other branch pulls in the other direction. This is to return our body to our natural state of homeostasis, or internal balance. Bilateral A function is equally represented by both sides of the brain. Brain stem The general area which connects the spinal column to the higher brain. Cerebellum An area of the brain which is situated behind the medulla and which co-ordinates voluntary movement, muscle tone and body balance. 74 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Cerebral dominance The side of the brain which has greater control over a particular function. Also called hemispheric dominance. Contralateral One hemisphere controls the opposite side of the body. Cortex The outermost layer of grey matter in the forebrain which controls higher cognitive and intellectual behaviour. Endocrine system The system of glands which produce hormones. Frontal lobe The largest part at the front of the brain. Hemisphere One half of a sphere. The brain is separated into two hemispheres, left and right. Hippocampus Located between the thalamus and the cortex, it is an area of the brain which is involved in learning and storing new information in memory. Hypothalamus An area of the brain situated below the thalamus. It integrates the activity of an ANS. It is the cognitive centre for emotions, stress, motivation and homeostasis. Limbic system An area of the brain which includes parts of the cortex and hypothalamus. It is important in emotion and motivation. Localisation Particular areas of the cerebral cortex are associated with specific physical or behavioural functions. Medulla Area of the brain which is situated at the base of the brain stem. It is the centre which controls heartbeat, breathing, swallowing, blood pressure, digestion, etc. APPROACHES AND METHODS IN PSYCHOLOGY (H) 75 TUTOR GUIDE Occipital lobe An area at the back of the brain which includes the visual cortex. Parietal lobe A brain area between the frontal and the occipital. Pituitary gland An endocrine gland located in the brain. It is attached to the base of the hypothalamus. It controls hormonal secretions and other ANS glands. Reticular activating system (RAS) An area found in the core of the brain stem. It is related to sleep, arousal, consciousness and attention. Temporal lobe An area of the brain which is situated on the side, below the occipital lobe. It contains the auditory cortex for hearing and balance. It also contributes to memory, language, emotion and perception. Thalamus An area of the brain which lies under the corpus callosum. It receives sensory data, performs some processing and passes the data on to the cerebral cortex. Glossary of terms – Section 6 Basic needs The most compelling human needs such as food and the avoidance of pain. In Maslow’s theory these are at the base of a hierarchy of needs and other requirements, even for physical safety, will be ignored until they are satisfied. Client-centred therapy A form of psychotherapy developed by Carl Rogers, based on a humanistic approach, in which the individual is considered to be the only person who can develop solutions or approaches to their problem. The role of the therapist is to facilitate such development. Empirical Such as can be measured. Empirical observations are those that can provide a level of objective data, which can be assessed in one form or another. 76 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Hierarchy A structured form of organisation constructed in levels, with each level overshadowing or dominating the lower ones. Humanistic psychology An approach within psychology which emphasises the whole person and their scope for change. Personality Those relatively enduring features which account for a person’s characteristic way of behaving. Some uses of the term ‘personality’ refer to patterns of behaviour rather than their causes. Some theories are concerned with the way the structures underlying personality are formed, i.e. Freud. Other theories try to find a biological basis for personality, i.e. Eysenck’s theory of types, while still others measure different aspects of people, i.e. Cattel’s traits. Glossary of terms – Section 7 Bias A prejudice, a leaning in one direction only. Biased sampling Some participants are more or less likely to be selected than they should be, given their frequency in the population. This leads to systematic errors in the data. Control group The participants who receive no treatment and act as a comparison with the experimental group for control purposes. Counterbalancing An experimental procedure for controlling irrelevant factors, especially order effects. Dependent variable The variable we look at to see if there are any changes produced by our manipulation of the causal variable. It is the variable we measure. Experimental group The group of participants who receive the experimental treatment. APPROACHES AND METHODS IN PSYCHOLOGY (H) 77 TUTOR GUIDE Experimenter effect An experimenter has expectations about the outcome of an experiment and may indirectly and unconsciously communicate these to the participant. This affects the participant’s behaviour. Field experiment An experimental manipulation of an independent variable that takes place in a natural setting rather than in the more artificial setting of the laboratory. Hypothesis A formal, unambiguous statement of what you predict. The research will either prove or disprove this prediction. Independent measures Comparison is made between two unrelated groups of participants. The participants are in groups not pairs. One group receives the experimental treatment, the other doesn’t. Their performance on the dependent variable is compared. Independent variable The variable we suspect is the causal variable. Laboratory experiment An investigation where the experimental manipulation of the independent variables takes place within such conditions that careful control of variables is possible. Natural experiment An investigation where the allocation of participants to the different experimental conditions is outside the control of the investigator, and is manipulated by some outside agency. Opportunity sampling Selecting participants because they are available. Order effects When participants are tested on two (or more) conditions (A and B) their performance may be improved or depressed by certain factors such as practice, fatigue or boredom. Population Total number of cases about which a specific statement can be made (sometimes called the target population). 78 APPROACHES AND METHODS IN PSYCHOLOGY (H) TUTOR GUIDE Quota sampling The population is divided into sections or strata. A fixed number of samples are taken from each section. Also called stratified sampling. Random sampling Every member of the population has an equal chance of being selected, therefore it is an unbiased sample. Can be achieved with random number tables or numbers drawn from a hat. Research An attempt to study a problem systematically. Research design The overall plan of action to maximise meaningful results and minimise ambiguity using research techniques. Control is an important feature of design. Research method A way of doing things in a systematic manner. Sample Part of a population selected such that it is considered to be representative of the population as a whole. Scientific method A series of procedures which produce an objective body of facts. Variable Something/anything that varies in a given situation. Volunteer sampling Participants who become part of an experiment because they volunteer when asked. This is not random.
