Difficulty Verdict
The combined papers present a balanced, medium-to-hard level of challenge (difficulty index 3.5). Paper 11 tests deep knowledge of the core studies and classic debates, while Paper 21 demands strong practical application of research design principles rather than simple rote memorisation.
Where the Marks Are Won or Lost
- Core Study Specifics: Precision in outlining procedures (such as a single trial in Perry et al.) and specific findings (such as Fagen et al.'s elephant learning results) is essential. Vague descriptions easily lose marks.
- Methodological Justification: In Paper 21, high-scoring candidates successfully link methodological choices back to the specific context of the prompt (e.g., explaining why right-handedness is crucial for brain scans to prevent lateralisation issues).
- Structured Comparisons: Paper 11's similarity essay (Dement & Kleitman vs. another study) often loses marks if candidates describe the studies in isolation instead of directly comparing specific, shared methodological features.
Examiner Pitfalls & Strategy
A major pitfall is failing to adhere to negative constraints, such as the instruction to avoid referencing brain measurement techniques in Paper 11, or omitting the required features in Paper 21's study design question. Students should always highlight the specific sub-prompts in research planning questions to ensure all components—such as question format, examples, and scoring—are fully addressed.
Future Predictions
Given the strong emphasis on animal guidelines and cognitive ethics in this series, future sessions are highly likely to shift focus toward the clinical approach and health psychology promote strategies. Revising diagnostic criteria and therapist-patient dynamics will be critical for upcoming cohorts.
