Difficulty Verdict

This exam series sits at a moderate difficulty level of 3.2 out of 5. While direct recall questions on topics such as the peripheral nervous system and definitions of abnormality provided accessible marks, students were pushed to their limits by highly specific application scenarios and demanding research methods calculations.

Where the Marks Are Concentrated

The majority of the marks are anchored in four high-value extended response questions. In Paper 1, the 12-mark essay on the learning theory explanation of attachment and the 8-mark Working Memory Model (WMM) essay required a clean balance of description (AO1) and evaluation (AO3). In Paper 2, the 12-mark essay on the cognitive approach and the 8-mark CBT for depression essay dominated the mark allocation.

Examiner Pitfalls & Crucial Misconceptions

Several common pitfalls were highlighted in the examiners' reports:

  • Asch's Conformity Findings: Many students incorrectly stated that '37% of participants conformed' instead of the precise finding that naïve participants conformed on 37% of the critical trials (or conformed on 32% of trials).
  • Romanian Orphan Studies: In the scenario comparing Katti (adopted at 5 years) and Cema (adopted at 5 months), generic descriptions of Romanian studies scored poorly. Full marks required explicit comparative analysis of their likely differing developmental trajectories.
  • Retroactive Interference: Students frequently confused proactive and retroactive interference when explaining Kaleb's difficulty in recalling the Multi-Store Model after learning the Working Memory Model.
  • Sign Test Calculation: Forgetting to ignore the 'nil differences' (participants reporting the same productivity) when identifying the value of \( S = 6 \) was a frequent error.

Revision Strategy & Future Predictions

With Research Methods accounting for 38 marks across both papers, mastering practical design, hypothesis writing, and non-parametric calculations is essential. Future series are highly likely to rotate focus toward the Multi-Store Model of Memory, minority influence / obedience variables, and the behavioral explanation and treatment of phobias, which were underrepresented in this series.
