A-Level Psychology

A-Level Psychology is the scientific study of mind and behaviour. It covers research methodology, cognitive processes, developmental psychology, social influence, biological bases of behaviour, and individual differences — all examined through empirical evidence and critical evaluation.

• Experimental design — laboratory, field, natural, and quasi-experiments; independent measures, repeated measures, matched pairs designs
• Sampling methods — random, systematic, stratified, opportunity, volunteer; strengths and limitations
• Data analysis — descriptive statistics (mean, median, mode, range, standard deviation); inferential statistics (sign test, chi-squared, Mann-Whitney U, Wilcoxon); choosing the right test
• Ethics — informed consent, deception, right to withdraw, confidentiality, debriefing; BPS code of conduct
• Validity and reliability — internal and external validity; improving reliability through standardisation

• Memory models — multi-store model (Atkinson & Shiffrin: sensory, short-term, long-term); working memory model (Baddeley & Hitch: central executive, phonological loop, visuospatial sketchpad, episodic buffer)
• Types of long-term memory — episodic, semantic, procedural; evidence from case studies (e.g., HM, Clive Wearing)
• Forgetting — interference theory (proactive and retroactive); retrieval failure (context-dependent and state-dependent cues)
• Eyewitness testimony — Loftus and Palmer; misleading information, anxiety, age; cognitive interview

• Attachment — Bowlby”s evolutionary theory; types of attachment (secure, insecure-avoidant, insecure-resistant); Ainsworth’s Strange Situation
• Maternal deprivation — Bowlby’s 44 thieves study; the critical period; effects of institutionalisation (Romanian orphan studies)
• Cultural variations — individualist vs. collectivist cultures; van Ijzendoorn and Kroonenberg’s meta-analysis

• Conformity — Asch’s line experiments; Normative Social Influence (NSI) and Informational Social Influence (ISI); variables affecting conformity
• Obedience — Milgram’s shock experiments; situational variables (proximity, location, uniform); agentic state theory
• Social change — how minority influence (consistency, commitment, flexibility) and majority influence create social change (e.g., civil rights movement)

• Nervous system — central nervous system (brain and spinal cord); peripheral nervous system (somatic and autonomic); sympathetic and parasympathetic divisions
• Brain localisation — motor cortex, somatosensory cortex, visual cortex, auditory cortex, Broca’s area, Wernicke’s area; evidence from case studies and brain scans
• Plasticity and functional recovery — the brain’s ability to reorganise after injury; axonal sprouting, recruitment of homologous areas
• Biological rhythms — circadian (sleep-wake cycle), ultradian (sleep stages), infradian (menstrual cycle); endogenous pacemakers and exogenous zeitgebers

• Psychopathology — definitions of abnormality (deviation from social norms, failure to function adequately, deviation from ideal mental health, statistical infrequency)
• Depression — behavioural, cognitive, and biological explanations; treatments (CBT, drug therapy)
• OCD — biological explanations (genetic, neural); drug therapy (SSRIs)
• Phobias — behavioural explanation (two-process model); systematic desensitisation and flooding

1. Use the PEEL structure. Point, Evidence (study/theory), Explanation, Link to the question. Every exam paragraph needs this.
2. Know key studies in detail. Aim, procedure, findings, conclusions, evaluation. For every major topic, memorise 2–3 landmark studies.
3. Evaluate using GRAVE. Generalisability, Reliability, Application, Validity, Ethics. Apply this to every research study you discuss.
4. Compare approaches. Be able to evaluate the biological, behavioural, cognitive, psychodynamic, and humanistic approaches for any given topic.
5. Practise research methods questions. They appear on every paper and carry significant marks. Know how to calculate and interpret statistical tests.

Each section provides key theories, landmark studies, evaluation points, and exam-style questions. Start with research methods (it underpins everything), then move through topics in order.

## Overview

This section provides comprehensive A-Level Psychology content for Psychology, covering all specification points with detailed explanations, worked examples, and practice questions.

Each page in this section includes:

• Definitions: Clear, precise explanations of key concepts
• Worked Examples: Step-by-step solutions with annotations
• Practice Questions: Multiple-choice and structured questions with mark schemes
• Common Pitfalls: Errors to avoid and how to fix them
• Exam Tips: Strategies for maximising marks in this topic

1. Read the introductory page to understand the topic overview
2. Work through each sub-topic in order
3. Attempt the practice questions before checking solutions
4. Use the flashcards to revise key terminology
5. Complete the diagnostic test to identify remaining gaps

• Core definitions and principles
• Application to examination-style questions
• Links to related topics across the specification
• Assessment objective alignment (AO1, AO2, AO3)

• Active Recall: Test yourself regularly rather than re-reading notes
• Spaced Practice: Revisit this topic at increasing intervals
• Interleaving: Mix with other topics during revision sessions
• Elaboration: Explain concepts in your own words

Focus on command word interpretation and mark scheme analysis. Practice timing yourself on questions to build speed and accuracy. Review examiner reports for this topic to understand common student errors.

Human behaviour emerges from the interaction of biological, cognitive, and social factors. Our brains are wired to respond to threats, form relationships, and seek meaning. Psychology reveals the hidden mechanisms behind everyday decisions - why we conform to groups, how memories form and fade, and what drives us to pursue goals. These insights apply to education, relationships, and personal wellbeing.
