Difficulty Verdict

This series sits at a solid 3.5 out of 5 in difficulty. While Paper 1 featured highly accessible short-answer questions, the later papers demanded precise mathematical and methodological application. Paper 2 and Paper 4 required students to design experiments and self-reports under strict structural guidelines, penalizing those who relied on pre-memorized textbook answers.

Where the Marks Are

A huge proportion of marks was concentrated in General Research Methods (37 marks) and Mood Disorders (32 marks). In Paper 1, the 10-mark evaluation on Saavedra & Silverman and the 8-mark comparison of Hözel with Dement & Kleitman were critical differentiators. In Paper 3 and 4, the 16-mark essay questions on OCD therapies (SSRIs vs ERP) and Work Motivation (Deci & Ryan) offered high-yield returns for students with structured essay-writing skills.

Examiner Pitfalls & Traps

  • Data Omission: In Paper 1 Q4, candidates frequently lost marks by not citing specific numerical data when comparing high-empathy oxytocin conditions (e.g., mean distance for the ball being 40, stranger being 8.4).
  • Ignoring Negations: On Paper 2 Q10a (Isla's experiment), many candidates wasted valuable time describing the sample or ethics, despite the prompt explicitly instructing: 'Do not describe sample/sampling technique or ethical issues.' This capped their score.
  • Motiveless Crimes: In Paper 3 Q3, students failed to recognize that diagnostic criteria (ICD-11) for pyromania require the *absence* of clear motives, making Emi's revenge-driven factory fire a major diagnostic complication.

Success Strategy

To secure top bands, students must treat research methods as a highly practical skill. When asked to plan a study, ensure you tick off the four mandatory 'imaginary columns' (independent variable, dependent variable, controls, and experimental design). For core studies, memorize exact mean values and participant demographics rather than rounding them.

Prediction for the Next Series

With Dement & Kleitman and Piliavin receiving relatively low-mark exposure in this series, expect these core studies to feature heavily in the upcoming series, potentially as major 10-mark evaluation or 8-mark comparison focus areas. Additionally, Schizophrenia biochemical explanations remain highly overdue for a dedicated essay.
