MATSEC Intermediate Psychology: Core Concepts and Exam Technique
What the paper tests
MATSEC Intermediate Psychology rewards precise terminology across the syllabus's core areas: research methods, biological, cognitive, learning, social, developmental, individual differences and abnormal psychology. Questions typically ask you to define a concept, apply it to a scenario, and evaluate a study or method.
Core rules and concepts
- Variables: the independent variable is manipulated; the dependent variable is measured. Operationalise both (e.g. 'words recalled from a 20-item list after 30 seconds').
- Methods: experiments can support causal claims; correlations show relationships only. Observations, questionnaires, interviews and case studies differ in validity, reliability and control.
- Ethics: informed consent, right to withdraw, confidentiality and protection from harm. Deception must be justified and followed by debriefing.
- Statistics: mean (affected by outliers), median (ordinal data), mode (categorical data), range and standard deviation for spread; significance is conventionally p < .05.
- Content anchors: Atkinson–Shiffrin multi-store model and Baddeley–Hitch working memory; Pavlov's classical and Skinner's operant conditioning; Asch conformity and Milgram obedience; Piaget's stages and Ainsworth's Strange Situation; definitions of abnormality and the DSM.
Worked example
A psychologist predicts that sleep deprivation lowers test scores. Students are randomly assigned to 4 hours' or 8 hours' sleep, then sit a 30-item test.
- IV: sleep condition (4 vs 8 hours), operationalised as time in bed.
- DV: score, operationalised as number correct out of 30.
- Design: independent measures, since each participant experiences one condition; random assignment reduces participant variables, though matched pairs could control ability.
- Conclusion: a significant difference supports the hypothesis but does not prove sleep is the sole cause.
Marks-losing traps
- Treating a correlation as proof of causation.
- Confusing repeated measures (same participants, order effects) with independent measures.
- Describing a study without naming its design, sampling method or ethical issues.
- Writing 'proves' where 'supports' is accurate.
- Ignoring demand characteristics and researcher bias when evaluating.
