A-Level Psychology: Abnormality and Phobias

Every psychopathology essay starts from the same deceptively simple question: what makes behaviour abnormal? This quiz covers the four definitions the specification requires and then applies the behavioural approach to phobias, the topic's first disorder.

The definition questions test each account with its evaluation attached: statistical infrequency and its twin weaknesses — no distinction between desirable and undesirable rarity, and blindness to disorders that are statistically common; deviation from social/cultural norms and its cultural relativity across time and place; failure to function adequately (in the flashcards and written questions); and Jahoda's deviation from ideal mental health, tested through her criteria such as resistance to stress. The multi-select format forces precision about which criticisms attach to which definition — the exact discrimination exam questions reward.

The phobia questions separate the behavioural, emotional and cognitive characteristics — avoidance and panic as behaviour, irrational beliefs as cognition — before testing the two-process model as a two-stage mechanism: acquisition by classical conditioning, maintenance by the negative reinforcement of avoidance. That acquisition-maintenance split is the analytical heart of the topic.

The therapy questions cover systematic desensitisation's three components (anxiety hierarchy, relaxation training, gradual exposure while relaxed) against flooding's single traumatic session, with two evaluation questions: the ethical concern flooding raises, and why desensitisation's gradualism and patient control make it the more acceptable treatment.

Every explanation states the principle and the evaluation point together, mirroring the describe-then-evaluate structure of psychopathology essays. The companion quiz covers depression and OCD.

State all four definitions of abnormality with their key limitations
Match each criticism to the correct definition
Classify phobia characteristics as behavioural, emotional or cognitive
Explain the two-process model's acquisition and maintenance stages
Compare systematic desensitisation and flooding on mechanism and ethics

Practice material written by Zestly on the AQA A-level Psychology (7182) topic Clinical Psychology and Mental Health (formerly Psychopathology), used as the example board: definitions in the field of mental health, the characteristics of phobias, the two-process model, and the behavioural therapies systematic desensitisation and flooding.

Sample question

Which of the following are recognised limitations of the 'statistical infrequency' definition of abnormality?

It fails to distinguish between desirable and undesirable infrequent behaviours.
It relies too heavily on subjective clinical judgment.
Some abnormal behaviours are statistically common in the population.
It defines abnormality as the breaking of unwritten social rules.

See the answer

It fails to distinguish between desirable and undesirable infrequent behaviours., Some abnormal behaviours are statistically common in the population.

Statistical infrequency defines abnormality as behaviours that are numerically rare. One limitation is that it cannot distinguish between desirable rarity (e.g. very high IQ) and undesirable rarity (e.g. severe depression). Another is that some disorders, like mild anxiety or depression, are statistically common, so the definition misses them. It is an objective, numerical approach (so it does not rely on subjective judgment), and 'breaking unwritten social rules' describes the deviation-from-social-norms definition, not this one.
