OCR A-Level Psychology Paper 1: what it covers

OCR A-Level Psychology Paper 1 (Component 01: Research Methods) runs 2 hours and is worth 90 marks. It covers the compulsory Research Methods content alongside one of three applied psychology options: Sleep and Dreaming, Criminal Psychology, or Sport and Exercise Psychology. Your school will have chosen one applied option, so make sure you actually know which.

Research Methods accounts for most of Paper 1's marks and is where students most often lose marks they didn't need to. It's also one of the most learnable sections going, since the content is fixed and the question types are predictable.

Research Methods is the highest-priority section

Research Methods questions turn up throughout Paper 1, and again in Papers 2 and 3. Get this content solid and it pays off across the whole exam, not just this paper.

Most frequently tested areas

  • Research design: experimental designs (independent groups, repeated measures, matched pairs), the advantages and disadvantages of each, and how to design a study for a given hypothesis.
  • Sampling: opportunity, volunteer, random, stratified, systematic. Know the definition, strengths and weaknesses of each.
  • Variables: operationalising IV and DV, confounding variables, extraneous variables, demand characteristics.
  • Reliability and validity: internal and external validity, test-retest and inter-rater reliability, and how to improve each.
  • Ethical guidelines: BPS guidelines, informed consent, right to withdraw, deception, debriefing, confidentiality, and how they apply to specific studies.
  • Data analysis: measures of central tendency and dispersion, normal distribution, statistical significance and Type I/II errors, and appropriate statistical tests (Spearman's rho, chi-squared, Mann-Whitney).
  • Qualitative vs quantitative data: the differences, advantages and limitations of each, plus thematic analysis.

Application questions

OCR frequently hands you a novel scenario, a described study or research situation, and asks you to apply Research Methods knowledge to it. Read the scenario carefully and link each methodological concept explicitly to the context given. A generic answer about research methods that never touches the scenario earns limited marks, no matter how accurate it is in the abstract.

Sleep and Dreaming, if this is your applied option

The highest-frequency topics here are the stages of sleep (NREM stages 1-4 and REM, their characteristics, the sleep cycle), theories of why we sleep (restoration theory from Oswald, evolutionary theory, and the strengths and weaknesses of each), theories of dreaming (Freud's wish fulfilment, activation-synthesis from Hobson and McCarley), sleep disorders (insomnia, sleep apnoea, narcolepsy, sleepwalking, their causes, characteristics and treatments), and research into sleep deprivation, including the methodological issues in the key studies.

Criminal Psychology, if this is your applied option

The highest-frequency topics here are definitions of crime and how social context shapes what counts as criminal, theories of criminal behaviour (social learning theory, Eysenck's theory of the criminal personality, biological explanations like genes and brain structure), profiling (top-down FBI and bottom-up investigative psychology approaches, with their strengths and weaknesses), treatment and punishment (zero tolerance policing, custodial sentencing, restorative justice, token economies, and how effective each actually is), and the key studies: Bandura's Bobo doll study, Raine et al.'s brain scanning study, Canter's geographic profiling.

How to answer OCR Psychology essays

OCR's extended answer questions, typically 8 or 12 marks, reward a structured response: make a point, support it with evidence from a named study, then evaluate the claim. Your evaluation should get into methodology, alternative explanations, or real-world applications, not just a generic "this study lacked ecological validity."

Name your studies accurately: researcher, year, brief method, finding. Examiners credit specific knowledge over vague references every time.

Revision strategy

Revise Research Methods through application practice: find a novel scenario and design or critique a study on the spot. Flashcards work well for key definitions and study details. For the applied topics, practise writing timed 8-mark answers using point, study evidence, evaluation, link back to the question.
