Topic D: Learning theories and development

Classical conditioning explains learning of reflexive, involuntary responses. A stimulus that naturally produces a response is paired with a previously neutral stimulus until that neutral stimulus can produce a learned response on its own.

Food naturally produces salivation, so food is the unconditioned stimulus (UCS) and salivation the unconditioned response (UCR). If a buzzer is repeatedly paired with food, the buzzer becomes the conditioned stimulus (CS) and salivation to it is the conditioned response (CR). Watson and Rayner applied the same logic to fear learning.

Operant conditioning explains how consequences alter the future frequency of voluntary behaviour. Reinforcement increases behaviour; punishment decreases it. Positive means something is added and negative means something is removed—it does not mean good or bad.

Primary reinforcers meet biological needs; secondary reinforcers acquire value through association. Continuous reinforcement can establish a response quickly, while intermittent schedules often make it more resistant to extinction. Shaping reinforces successive approximations until the target behaviour is reached.

Social learning theory proposes that people can learn by observing models and the consequences those models receive. Learning can occur without immediate performance, so observation is not the same as automatic imitation.

A model is more influential when the learner identifies with them—for example through perceived similarity, status or attractiveness. Direct reinforcement affects the learner’s own behaviour; vicarious reinforcement occurs when observing another person rewarded and makes imitation more likely. Observed punishment can inhibit performance.

Freud proposed that behaviour is influenced by unconscious conflict. The id seeks immediate gratification, the ego negotiates with reality, and the superego represents internalised moral standards. Anxiety arises when these demands conflict, and defence mechanisms protect the ego by distorting or redirecting experience.

In the phallic stage Freud described the Oedipus conflict and identification with the same-sex parent as routes to superego development. These are historical theoretical claims, not established facts about every child. Object-relations approaches instead emphasise how early caregiver relationships become internal templates for later relationships.

Systematic desensitisation is a behavioural treatment for phobias. It uses counterconditioning: relaxation is paired with gradually stronger versions of the feared stimulus so that a calm response competes with anxiety. This is often described as reciprocal inhibition.

Exposure may be imagined or in vivo. Small achievable steps and client control can make treatment acceptable, while repeated practice weakens avoidance and provides new evidence that the situation is manageable. Capafóns et al. applied a standardised hierarchy-based programme to fear of flying.

Psychoanalysis aims to make unconscious conflicts and relationship patterns conscious so that they can be understood rather than repeatedly acted out. The therapist listens for recurring meanings rather than treating one statement as a direct measurement of the unconscious.

Interpretations should be tentative and developed through the therapeutic relationship. Insight may help a client notice a repeated defence or relationship pattern and try a different response.

Observation records behaviour as it occurs. A useful design turns an aim into mutually clear behavioural categories, a sampling rule and a recording system, so another observer could apply the same decisions.

Natural settings can improve ecological validity; structured settings provide more control. Observers need the same viewpoint and rules. Where practical, video allows checking, but recording requires specific consent and secure handling.

Observation designs are classified along independent dimensions. A study may be participant and naturalistic, or non-participant and structured; overt/covert describes awareness rather than setting.

Choose the combination from the research question. If the aim is to count helping under identical conditions, a structured non-participant observation may improve comparability. To understand naturally occurring group behaviour, a participant naturalistic design may supply richer context.

Content analysis is a systematic method for examining communication such as articles, posts, interviews or videos. It can produce quantitative counts, qualitative interpretations, or both, but its sampling and coding rules must be explicit.

A coding manual should include definitions and borderline examples. Quantitative counts improve transparency; qualitative notes can preserve context. Anonymise personal material and respect copyright, privacy and the expectations of the source community.

Freud developed psychodynamic ideas through intensive case studies of individual clients. Case material could include interviews, free association, dreams, slips and remembered childhood events, producing an idiographic account of one person over time.

A strong case report separates what the client said or did from the analyst’s interpretation, preserves confidentiality, considers alternative explanations and avoids claiming that improvement proves the theory.

List A supplies descriptive tools used throughout psychology. The choice depends on measurement level, distribution and the question; computing every statistic does not improve an analysis.

Inspect unusual scores, verify totals and use consistent units. A labelled graph communicates the operationalised variable, while a table should allow the reader to reconstruct how the summary was obtained.

Thematic analysis identifies patterned meaning in qualitative data. It can be inductive, allowing codes to arise from the material, or deductive, applying concepts chosen in advance. Either way, the researcher must show how interpretation was produced.

A reflexive log records how assumptions and decisions affected the analysis. A second coder can test whether a structured codebook is applied consistently, while discussion of disagreements can reveal ambiguous definitions. Frequencies may supplement a theme but do not create it.

The chi-square test of independence compares observed frequencies in a contingency table with frequencies expected if two categorical variables were unrelated. Data must be counts in mutually exclusive categories, with each case contributing to one cell.

For each cell, calculate $E=( ext{row total} imes ext{column total})/ ext{grand total}$. Then calculate each contribution $(O-E)^2/E$ and add them. Degrees of freedom are $(r-1)(c-1)$. Check expected frequencies and the table required by Pearson before interpreting the statistic.

UK animal research is governed by the Animals (Scientific Procedures) Act 1986 and Home Office licensing. Legal permission does not end ethical evaluation: the likely scientific or social benefit must justify the harms and no suitable less harmful method should answer the question.

Animals allow controlled, invasive or developmental research that could not ethically be conducted on humans. Standardisation may strengthen causal inference, but stress, artificial housing and species differences can change behaviour and restrict generalisation.

Watson and Rayner investigated whether an emotional response could be classically conditioned, generalise to similar objects and persist over time in a young child known as Albert.

At about nine months Albert showed no fear of a white rat, rabbit, dog, monkey, masks, fur or burning newspaper, but a hammer striking a steel bar startled him. At 11 months the rat was paired with the loud noise. Later tests presented the rat alone, similar furry objects and a different room; blocks were used between trials to calm him.

Capafóns et al. tested whether systematic desensitisation reduced fear of flying. Forty-one media-recruited volunteers were randomly allocated to treatment ($n=20$) or no-treatment control ($n=21$); groups did not differ on pre-treatment measures.

Interviews and established scales measured flight fear, catastrophic thoughts and physiological symptoms. Heart rate, muscle tension and skin temperature were recorded while participants watched a video covering a journey from packing to landing. Treatment involved two one-hour sessions per week, at least 12 and at most 15, using a hierarchy, brief relaxation, thought stopping, imagery and in-vivo techniques.

Prot et al. examined links among prosocial-media use, empathy and prosocial behaviour, including whether age, gender and culture moderated them. The researchers used complementary cross-sectional and longitudinal studies.

Across cultural groups, greater prosocial-media use was associated with greater empathy and prosocial behaviour. At each longitudinal wave the same positive relationships appeared; Time 1 prosocial-game use predicted greater Time 3 prosocial behaviour, while violent-game use predicted less. Changes in empathy helped explain these links.

Bastian et al. tested whether violent game play changes how human participants perceive themselves and other players. Random allocation compared violent and non-violent games, allowing a stronger causal inference for the immediate laboratory effect.

Participants rated human-nature qualities after play. Study 2 also measured mood with PANAS and state self-esteem to test whether a general negative feeling explained the result. The reported self-humanity difference remained the central finding.

The Topic D practical uses observation to investigate learned behaviour. It must include two observations, or one observation producing both qualitative and quantitative data, and report what was recorded rather than inferring motives.

A structured observation might compare frequencies of clearly defined helpful acts across two contexts. If categories include perceived gender or age, state how observers coded it, recognise uncertainty and avoid treating group differences as innate or binary. Driving speed or politeness can be recorded only with safe, lawful procedures.
