Topic 1

The biological approach

The biological approach explains behaviour by looking at the brain, the hormones and the genes that produce it.

Picture itSomeone becomes aggressive after a head injury. Their personality has changed, and nothing about their upbringing or their beliefs has altered. Something physical did. That observation — that damaging tissue changes behaviour — is the foundation of the whole approach.

The core assumptions

Behaviour has a physical cause: brain structure, neurotransmitters, hormones, genetics and evolution. Because these can be measured, biological research tends to be highly objective and replicable. Its weakness is the same as its strength — it can be reductionist, explaining complex behaviour purely in physical terms.

Localisation of function

Different brain regions have different specialisms — language areas, the visual cortex, the amygdala in emotion. Evidence comes from brain damage cases, from scanning studies, and from split-brain research on patients whose hemispheres were surgically separated.

Neurotransmitters and hormones

Chemical messengers across synapses affect mood, arousal and attention. Dopamine, serotonin and noradrenaline recur throughout the syllabus. Hormones such as cortisol and testosterone act more slowly and more widely, which is why their behavioural effects are broad rather than specific.

Research methods used

Brain scanning (MRI, fMRI, PET), case studies of brain-damaged patients, animal studies, twin and adoption studies. Each has particular strengths — scans are objective, case studies are rich — and particular limits, especially generalisability from single cases and from animals.

Evaluating the approach

Strengths: scientific, objective, has produced effective drug treatments. Weaknesses: reductionist, can be deterministic, often ignores social and cultural context, and correlational brain findings are frequently reported as if they were causal.

The bit that catches people outA brain area being active during a behaviour does not mean it causes that behaviour. Scanning studies are correlational: the activity could be a consequence, or both could follow from something else. Reading a scan as proof of cause is the standard error in this approach.

Why are twin studies used to investigate genetic influence?
Identical twins share 100% of their genes and non-identical twins about 50%. If identical twins are more similar on a behaviour, that difference suggests a genetic contribution — although shared environment is a confounding factor.
Give one strength and one weakness of using brain scans in psychology.
Strength: they give objective, quantifiable data about a living brain without surgery. Weakness: they show correlation between activity and behaviour, not causation, and are expensive with limited sample sizes.

Topic 2

The cognitive approach

The cognitive approach treats the mind as an information processor: input goes in, something happens to it, and behaviour comes out.

Picture itYou cannot see memory. But you can give someone a list of words, vary how they are presented, and measure what they recall. From the pattern of what is remembered and forgotten, you can infer the structure of a system you never observed directly — which is exactly how the approach works.

The core assumptions

Mental processes — attention, perception, memory, language, thinking — can be studied scientifically by inference from behaviour. The mind is often compared to a computer, with encoding, storage and retrieval, though the analogy has limits.

Memory models

The multi-store model proposes sensory, short-term and long-term stores differing in capacity, duration and encoding. The working memory model subdivides short-term memory into a central executive, phonological loop and visuo-spatial sketchpad, explaining why two tasks using the same component interfere.

Schema theory

A schema is an organised packet of prior knowledge. Schemas help us interpret ambiguous information quickly, but they also distort memory — we reconstruct events to fit expectations, which is why eyewitness testimony can be confidently wrong.

Attention and perception

Selective attention explains how we filter an overwhelming input. Perception is active: the brain constructs an interpretation using both the sensory data and existing expectations. Visual illusions are the clearest demonstration that perception is inference, not recording.

Research methods and evaluation

Mostly laboratory experiments, giving high control and replicability. The trade-off is ecological validity — recalling nonsense syllables in a lab is not remembering where you left your keys. The approach is also criticised as mechanistic, downplaying emotion and motivation.

The bit that catches people outMemory is reconstructive, not a recording. Every recall rebuilds the event from fragments plus expectations, which is why confidence and accuracy are only weakly related — a witness can be certain and mistaken at the same time.

Check you have got it

Why can two tasks be performed at once if they use different working memory components?
Each component has its own limited capacity. Tasks using different components — one verbal, one visual — do not compete for the same resource, so performance is largely preserved.
Give one reason laboratory memory experiments may lack ecological validity.
The materials and setting are artificial — recalling word lists under instruction bears little resemblance to everyday remembering, which is emotionally significant and cued by context.

Topic 3

The learning approach

The learning approach says behaviour is acquired from the environment — through association, through consequences, and through watching others.

Picture itA child who has never touched a hot stove learns to avoid it after once seeing a sibling burnt. No conditioning happened to that child at all. Bandura's insight was that we learn from other people's consequences as well as our own, which massively expands what learning can explain.

Classical conditioning

Learning by association. A neutral stimulus paired repeatedly with an unconditioned stimulus becomes a conditioned stimulus producing a conditioned response. Also: generalisation to similar stimuli, discrimination between them, extinction when the pairing stops, and spontaneous recovery.

Operant conditioning

Learning by consequence. Positive reinforcement adds something desirable; negative reinforcement removes something unpleasant — both increase behaviour. Punishment decreases it. Schedules of reinforcement matter: variable ratio schedules produce the most persistent behaviour, which is why gambling is so hard to stop.

Social learning theory

Learning by observation and imitation. Bandura's four processes: attention, retention, reproduction and motivation. Vicarious reinforcement — seeing someone else rewarded — increases imitation, and models who are similar, admired or powerful are imitated more.

Applications

Systematic desensitisation and flooding for phobias, token economies in institutions, behaviour modification in classrooms, and understanding media influence on aggression. The approach's practical usefulness is one of its strongest arguments.

Evaluating the approach

Strengths: testable, well supported experimentally, highly applicable. Weaknesses: much evidence comes from animals, it largely ignores biological and cognitive factors, and it can be criticised as environmentally deterministic — treating people as passive products of their history.

The bit that catches people outNegative reinforcement is not punishment. Both involve something unpleasant, but negative reinforcement removes it and therefore increases the behaviour, while punishment adds something aversive to decrease it. This distinction is examined constantly and confused constantly.

A child stops whining when their parent gives in. What is being reinforced, and how?
The parent's giving-in is negatively reinforced — the unpleasant whining stops — making them more likely to give in next time. The child's whining is positively reinforced by getting what they wanted.
Why is a variable ratio schedule so resistant to extinction?
Because reinforcement is unpredictable, the absence of a reward is indistinguishable from a normal gap between rewards, so the behaviour continues for a long time before the person concludes it has stopped paying off.

Topic 4

The social approach

The social approach explains behaviour by the situation people find themselves in rather than by the kind of person they are.

Picture itOrdinary people did extraordinary things in Milgram's laboratory not because they were cruel but because of where they were standing, who was giving the instructions and how the responsibility appeared to be distributed. The situation, not the disposition, did most of the work.

Core assumptions

Behaviour is strongly shaped by other people, real or imagined, and by the roles and norms of the situation. The fundamental attribution error is our tendency to explain others' behaviour by their character while explaining our own by our circumstances.

Obedience and authority

Obedience rises with the perceived legitimacy and proximity of the authority, the physical distance from the victim, the presence of a uniform, and the availability of an agentic state in which people see themselves as the instrument of another's will rather than as responsible actors.

Conformity

Normative influence is conforming to be accepted; informational influence is conforming because you believe others know better. Group size, unanimity and task difficulty all affect conformity rates — and a single dissenter dramatically reduces it.

Social identity and prejudice

Categorising people into in-groups and out-groups is enough by itself to produce favouritism and discrimination. Realistic conflict theory adds competition for scarce resources; contact under cooperative, equal-status conditions towards a shared goal reduces prejudice.

Ethics in social research

This approach raises the sharpest ethical questions in psychology: deception, lack of informed consent, psychological harm, and the right to withdraw. Modern research uses ethics committees, debriefing and role-play alternatives — which increase protection and reduce realism at the same time.

The bit that catches people outSituational explanations do not excuse behaviour, and the exam does not expect them to. They explain how ordinary people come to do harmful things, which is a different claim from saying they were not responsible — and being clear about that distinction is worth marks.

Check you have got it

Why does the presence of one dissenter sharply reduce conformity?
It breaks the group's unanimity, which reduces normative pressure and shows that disagreement is possible without total isolation — so the participant no longer faces the whole group alone.
Give one reason a social psychology study might use deception despite the ethical cost.
If participants knew the true aim, they would alter their behaviour and the study would measure nothing real. The researcher must weigh that necessity against the harm, and debrief fully afterwards.

Topic 5

Research methodology

Method is not a preliminary to psychology — it is what makes a psychological claim worth believing rather than just interesting.

Picture itTwo studies reach opposite conclusions about the same question. Deciding which to believe means examining how each was done: who was studied, what was controlled, how variables were measured. Method is where the argument actually happens.

Experimental designs

Laboratory experiments give high control and easy replication but low ecological validity. Field experiments are more realistic with less control. Natural and quasi experiments study naturally occurring conditions where manipulation is impossible or unethical.

Design and variables

Independent measures avoids order effects but risks participant differences. Repeated measures controls those differences but introduces order effects, dealt with by counterbalancing. Matched pairs tries for both. An operational definition states exactly how each variable is measured.

Non-experimental methods

Observation (naturalistic or controlled, participant or non-participant, covert or overt), self-report (questionnaires and interviews), case studies, and correlational studies. Each fits particular questions, and none can establish causation except an experiment.

Sampling and reliability

Random, opportunity, volunteer, snowball and stratified sampling differ in representativeness and practicality. Reliability is consistency — test-retest, inter-rater. Validity is whether you are measuring what you claim: internal, external, ecological, construct.

Data and ethics

Quantitative data is easy to analyse and compare but can lose meaning; qualitative data is rich but harder to summarise objectively. Ethical requirements: informed consent, no deception without justification, protection from harm, right to withdraw, confidentiality, and debriefing.

The bit that catches people outA correlation cannot establish cause. Two variables can move together because one causes the other, because the causation runs the other way, or because a third variable causes both. Every correlational finding needs that sentence somewhere in its evaluation.

Check you have got it

Why does a repeated measures design need counterbalancing?
Because doing one condition first can affect performance in the second through practice or fatigue. Varying the order across participants means these order effects cancel out rather than favouring one condition.
A study finds ice cream sales correlate with drowning deaths. What is the likely explanation?
A third variable — hot weather — causes both. This is why correlation cannot establish causation.

Topic 6

Issues and debates

The same behaviour can be explained several ways, and choosing between explanations is itself a psychological argument.

Picture itWhy is someone anxious? Genes, learned associations, distorted thinking, and social circumstances are all plausible answers, and all are supported by evidence. The debates in this topic are about how to hold several true explanations at once without pretending one is the whole story.

Nature versus nurture

Almost no behaviour is purely one or the other. The modern position is interactionist: genetic predispositions are expressed differently in different environments. The diathesis-stress model captures this — a vulnerability plus a trigger.

Reductionism and holism

Reductionism explains behaviour at the simplest level — neurotransmitters, stimulus-response. It is scientific and testable but can lose the phenomenon being explained. Holism considers the whole person in context: more complete, harder to test.

Determinism and free will

Determinism holds that behaviour is caused by factors outside our control, whether biological, environmental or psychic. Free will holds that people choose. This matters practically — for legal responsibility, and for whether therapy assumes people can change.

Individual and situational explanations

Is behaviour caused by the kind of person or the kind of situation? Social psychology consistently shows the situation is more powerful than intuition suggests, while the fundamental attribution error means we consistently underestimate it.

Cultural and gender bias

Ethnocentrism judges other cultures by one's own standards. Much classic research used Western, educated, industrialised samples and generalised universally. Alpha bias exaggerates gender differences; beta bias minimises or ignores them; androcentrism treats male behaviour as the norm.

The bit that catches people outThe nature-nurture debate is not a question to be answered but a false dichotomy to be dissolved. The productive question is how genes and environment interact, not which one wins — and answers that pick a side score less than those that explain the interaction.

Explain the diathesis-stress model using an example.
A person may inherit a vulnerability to depression, but it only develops if a sufficient environmental stressor — bereavement, unemployment — occurs. Neither factor alone is sufficient, which explains why identical twins are not always concordant.
Why is a determinist position problematic for the legal system?
If behaviour is entirely caused by factors outside a person's control, the basis for holding them morally and legally responsible is weakened — yet legal systems require the assumption that people could have chosen otherwise.

Topic 7

Clinical psychology

Clinical psychology studies how psychological disorders are defined, explained and treated — and every one of those three steps is contested.

Picture itDeciding that a set of behaviours constitutes a disorder is a judgement, not a measurement. The line between eccentricity and illness moves between cultures and across decades. That does not make the distress unreal — it means the categories must be handled carefully.

Defining abnormality

Statistical infrequency, deviation from social norms, failure to function adequately, and deviation from ideal mental health. Each captures something and misses something: statistical rarity would classify exceptional intelligence as abnormal, and social norms vary by culture and change over time.

Diagnosis and its problems

Classification systems provide shared criteria and enable research and treatment. The difficulties are reliability (do two clinicians agree?), validity (does the category describe something real?), comorbidity, cultural bias, and the effects of labelling on how a person is treated and sees themselves.

Explanations of disorders

Biological: genetics, neurotransmitter imbalance, brain structure. Cognitive: negative automatic thoughts, faulty attributions, cognitive triad. Behavioural: conditioned associations and reinforcement. Psychodynamic and social factors add further layers. Most disorders are best understood as interactions of several.

Treatments

Biological: drug therapy — effective and accessible, but with side effects and treating symptoms rather than causes. Psychological: CBT, systematic desensitisation, flooding, token economies. Effectiveness varies by disorder, and combined treatment often outperforms either alone.

Evaluating treatment

Consider effectiveness (compared to what?), appropriateness for the disorder and the person, cost, availability, side effects, relapse rate, and how outcome was measured. A treatment that works in a trial with selected participants may work less well in practice.

The bit that catches people outA drug that relieves symptoms does not prove the disorder was caused by the thing that drug affects. Paracetamol relieves headache without headaches being caused by a paracetamol deficiency — and the same logic applies to neurotransmitter theories.

Check you have got it

Give one limitation of defining abnormality by deviation from social norms.
Social norms vary between cultures and change over time, so the same behaviour could be classed as disordered in one place or era and normal in another — which makes the definition relative rather than objective.
Why might combined drug and psychological treatment outperform either alone?
Medication can reduce symptoms enough for the person to engage with therapy, while therapy addresses the thinking and behaviour patterns that medication does not, reducing relapse when the drug is stopped.

Consumer psychology

Consumer psychology applies psychological principles to how people choose, buy and use products — and to how environments are designed to influence them.

Picture itSupermarkets put staples at the back, play slow music, and place high-margin items at eye level. None of this is accidental, and none of it is announced. Consumer psychology is the study of those influences, from both sides — how they work, and how consumers might resist them.

The physical environment

Store layout, atmospherics (music, lighting, scent, colour), crowding and queue design all affect how long people stay and how much they spend. Slower music and pleasant scents increase dwell time; crowding reduces satisfaction and increases the chance of leaving without buying.

The psychological environment

Menu design and pricing psychology — removing currency symbols, decoy options, price endings. Anchoring makes a subsequent price seem reasonable relative to a first one. Sound and colour affect perceived quality and speed of eating.

Consumer decision making

Models describe stages: need recognition, information search, evaluation, purchase, post-purchase evaluation. In practice people use heuristics — rules of thumb — rather than full evaluation, and cognitive dissonance after purchase drives them to justify what they bought.

Product design and packaging

Attention is drawn by contrast, movement, faces and novelty. Packaging communicates quality, portion size and brand identity before any information is read. Eye-tracking and attention research are used extensively in testing designs.

Advertising and brand awareness

Types of appeal (fear, humour, celebrity, testimonial), the elaboration likelihood model's central and peripheral routes to persuasion, and brand recognition and loyalty. Effectiveness is measured by recall, attitude change and sales — which do not always agree.

The bit that catches people outThis topic sits closest to real-world persuasion, so its ethics matter. Techniques that work by exploiting known biases — anchoring, artificial scarcity, deliberately confusing pricing — raise a genuine question about consumer autonomy that the exam is happy for you to raise.

Why do supermarkets often place bread and milk at the back of the store?
Most customers come for these staples, so placing them furthest from the entrance means shoppers walk past many other products, increasing exposure and unplanned purchases.
How does anchoring affect a customer looking at a discounted item?
The displayed original price acts as an anchor, so the reduced price is judged relative to it and seems a better deal than it would if seen alone.

Topic 9

Health psychology

Health psychology studies why people behave in ways that damage their health, and what actually changes that behaviour.

Picture itAlmost every smoker knows smoking is harmful. Information alone therefore cannot be the answer, or nobody would smoke. Health psychology exists because the gap between knowing and doing is where the real problem sits.

Adherence to medical advice

Non-adherence is common and expensive. It may be intentional (deciding not to, because of side effects or beliefs about the illness) or unintentional (forgetting, misunderstanding). Measurement is difficult: self-report is unreliable, pill counts can be gamed, biological measures are costly.

Pain

Types: acute, chronic, phantom limb. Measured by self-report scales, behavioural observation and psychometric questionnaires. Managed biologically (analgesics) and psychologically (attention diversion, imagery, cognitive redefinition, biofeedback, hypnosis).

Stress

Sources: work, life events, daily hassles, lack of control. Measured physiologically (cortisol, heart rate), by self-report scales, and by combinations. Managed by biological means, by cognitive approaches such as stress inoculation training, and by increasing perceived control and social support.

Health promotion

Fear appeals work only when combined with a clear, achievable action — otherwise people avoid the message. The health belief model (perceived susceptibility, severity, benefits, barriers, cues to action) and the theory of planned behaviour predict who acts on health advice.

Health-risk behaviours

Substance use, unhealthy eating, inactivity, unsafe practices. Explained biologically (dependence, reward pathways), by learning (conditioned cues, reinforcement) and socially (peers, norms, availability). Effective interventions usually address more than one level.

The bit that catches people outFear appeals can backfire. If a message raises fear without providing a manageable action, people reduce the discomfort by rejecting or avoiding the message instead of changing the behaviour — which is why graphic campaigns sometimes achieve nothing.

Why might a patient intentionally stop taking prescribed medication?
Because of unpleasant side effects, a belief that the illness has passed once symptoms improve, doubts about the medication's necessity, cost, or a poor relationship with the prescriber.
Why is self-report a weak measure of adherence?
Patients under-report non-adherence because of social desirability — they know what the doctor wants to hear — and may also genuinely misremember what they took.

Topic 10

Organisational psychology

Organisational psychology asks what makes people effective and satisfied at work, and how leadership and group structure affect both.

Picture itTwo teams with the same skills, the same resources and the same task produce very different results. The difference is in how they are led, how the work is designed, and how decisions are made. Organisational psychology is the study of that difference.

Motivation at work

Need theories: Maslow's hierarchy, Alderfer's ERG. Cognitive theories: equity theory (people compare their input-output ratio to others'), expectancy theory (effort leads to performance leads to a valued reward). Goal-setting theory: specific, difficult, accepted goals with feedback outperform 'do your best'.

Leadership and management

Trait, behavioural, contingency and transformational approaches. Transformational leaders raise motivation through vision and individual attention; transactional leaders exchange reward for performance. Contingency theories argue the effective style depends on the situation, not the leader.

Group behaviour and decision making

Groupthink occurs when cohesive groups suppress dissent to preserve harmony, producing poor decisions. Group polarisation pushes group decisions towards the extreme of the initial leaning. Social loafing reduces individual effort when contributions are not identifiable.

Job satisfaction and the working environment

Measured by questionnaires and interviews. Affected by pay, autonomy, task variety, feedback, relationships and physical conditions. Related to absenteeism, turnover and sabotage — though the link with productivity is weaker than intuition suggests.

Organisational work conditions

Shift patterns and circadian disruption, temperature, noise, lighting, open-plan design, and ergonomics. Errors and accidents rise on night shifts and after long hours — a finding with direct implications for safety-critical industries.

The bit that catches people outSatisfied workers are not automatically more productive. The correlation is real but modest, and causation may run either way — success at work can create satisfaction as easily as satisfaction creates success. Assuming the simple version is a standard evaluation error.

Why does making individual contributions identifiable reduce social loafing?
When effort can be traced to a person, they are accountable for it, so the incentive to coast on the group's output disappears.
