How many core studies do I need to know for Component 02?

You need to know all 20 core studies prescribed by OCR. These are divided into five themes, each with four studies. For example, social psychology includes Milgram (obedience), Bocchiaro (disobedience), Piliavin (bystander behaviour), and Levine (cross-cultural helping). You must know the aims, procedures, findings, conclusions, and evaluations for each study.

What is the best way to memorise the core studies?

Use active recall and spaced repetition. Create summary tables for each study with columns for theme, aim, method, results, conclusions, and evaluation points. Test yourself regularly using flashcards or apps like Anki. Also, practice writing timed evaluation paragraphs to improve recall under exam conditions.

How are the core studies assessed in the exam?

Component 02 is assessed through a 2-hour written paper worth 105 marks (35% of A-Level). It includes short-answer questions (e.g., 'Outline one finding from Milgram's study') and extended writing (e.g., 'Evaluate the methodology of Loftus and Palmer's study'). Questions often ask you to compare studies or apply findings to novel scenarios.

Do I need to know the dates of the core studies?

Yes, knowing the year of publication is important for demonstrating precise knowledge. For example, Milgram (1963), Loftus and Palmer (1974), and Bandura (1961). Dates can help you discuss historical context, such as how ethical standards have changed over time.

Can I use the same evaluation points for different studies?

Yes, but you must tailor them to the specific study. For example, many studies have issues with generalisability due to small or biased samples. However, the specific sample details differ: Milgram used 40 American men, while Bandura used 36 boys and 36 girls from Stanford University Nursery School. Always reference the actual sample.

How do I link core studies to the themes?

Each theme has a key debate or issue. For social psychology, it's the power of the situation vs. individual dispositions. When evaluating a study, explicitly state how it supports or challenges this debate. For example, Milgram's findings support the situational explanation, while Bocchiaro's study shows that some individuals resist authority, highlighting dispositional factors.

Psychological themes through core studies (Component 02)

OCR

A-Level

Applied psychology (Component 03) requires learners to study one compulsory section, Issues in mental health, and two out of four optional applied psychology topics: Child psychology, Criminal psychology, Environmental psychology, or Sports and exercise psychology. The component focuses on background, key research, and applications, while requiring learners to apply methodological issues and debates across these topics.

Topic Overview

Psychological themes through core studies (Component 02) is a central component of the OCR A-Level Psychology specification. It requires students to explore 20 core studies across five key themes: social psychology, cognitive psychology, developmental psychology, individual differences, and biological psychology. Each theme is examined through four classic and contemporary studies, allowing students to understand how psychological theories are developed, tested, and refined. This component emphasises critical evaluation of research methods, ethical considerations, and the application of findings to real-world contexts, preparing students for both the examination and further study in psychology.

Mastering this component is crucial because it forms the basis for understanding how psychological knowledge is constructed. By engaging with landmark studies such as Milgram's obedience research, Loftus and Palmer's eyewitness testimony experiments, and Bowlby's attachment theory, students learn to analyse strengths and limitations of different methodologies, including experiments, observations, and case studies. This critical thinking skill is directly assessed in the examination, where students must evaluate studies and discuss their implications. Moreover, the themes link to other components, such as debates in psychology (Component 03), making this knowledge foundational for the entire A-Level.

In the wider subject, this component demonstrates the dynamic nature of psychology as a science. It highlights how research can challenge assumptions, inform policy, and improve lives—for example, how understanding memory distortions can enhance legal procedures, or how knowledge of attachment can influence childcare practices. Students who engage deeply with these studies develop a nuanced appreciation of psychological evidence, which is essential for any career in psychology, education, or research.

Key Concepts

Core ideas you must understand for this topic

→Core studies: The 20 prescribed studies (e.g., Milgram, Loftus & Palmer, Bandura) that must be known in detail, including aims, procedures, findings, conclusions, and evaluations.
→Themes: The five areas (social, cognitive, developmental, individual differences, biological) that group the studies and highlight key debates, such as nature vs. nurture or individual vs. situational explanations.
→Research methods: Understanding the strengths and weaknesses of experimental, observational, correlational, and case study designs used in the core studies, including issues of validity, reliability, and sampling.
→Ethical considerations: Applying ethical guidelines (e.g., informed consent, deception, protection from harm) to evaluate studies, and discussing how ethics have evolved over time.
→Application: Using findings from core studies to explain real-world phenomena, such as why people obey authority or how memory can be distorted by leading questions.

Examiner Tips

Expert advice for maximising your marks

💡Prepare for the application section by practicing with a variety of novel sources such as newspaper articles, blogs, or diary entries
💡Ensure you can link methodological issues (e.g., validity, reliability, sampling bias) to the specific key research studies
💡Practice applying the debates (e.g., nature/nurture, freewill/determinism) across all studied topics
💡Be ready to make evidence-based suggestions in relation to novel sources provided in the exam
💡Ensure you are familiar with the full references for all key research studies listed in Appendix 5f
💡Use the 'PEE' structure (Point, Evidence, Explanation) for evaluation paragraphs. For example: 'One strength of Loftus and Palmer's study is its high control (point). They used standardised video clips and questionnaires (evidence). This increases internal validity, allowing cause-and-effect conclusions about leading questions (explanation).'
💡Always link your evaluation to the theme or debate. If discussing a social psychology study, mention how it supports or challenges the situational explanation. For instance, when evaluating Milgram, note that it demonstrates the power of situational factors over dispositional ones, linking to the theme of social influence.
💡Memorise key details: dates, sample sizes, and specific findings (e.g., Milgram's 65% obedience rate). Examiners look for precise knowledge. Use mnemonics or flashcards to recall these facts under time pressure.

Common Mistakes

Pitfalls to avoid in your exam answers

Failing to apply methodological issues and debates to the specific applied topics
Inability to relate key research to novel situations provided in the exam
Lack of depth in explaining the background of mental health issues
Inadequate evaluation of the application of psychological theories to real-world scenarios
Misconception: 'All core studies are experiments.' Correction: While many are experiments (e.g., Milgram, Loftus & Palmer), others are observations (e.g., Bandura's Bobo doll study), case studies (e.g., HM), or correlational studies (e.g., Sperry's split-brain research). Students must identify the correct method for each study.
Misconception: 'Evaluation only means criticising the study.' Correction: Evaluation requires a balanced discussion of strengths and limitations, including methodological, ethical, and cultural issues. For example, Milgram's study has high internal validity but low ecological validity and ethical concerns.
Misconception: 'Themes are separate topics.' Correction: Themes overlap and connect. For instance, individual differences (e.g., personality) can influence social behaviour (obedience), and biological factors (e.g., brain structure) can affect cognitive processes (memory). Examiners reward links across themes.
