The characteristics, causes and treatment of phobias, for GCSE Psychology.
A phobia is an intense, irrational fear of a specific object or situation, strong enough to interfere with everyday life, going well beyond normal caution or nervousness.
Phobias typically involve behavioural symptoms (avoidance), emotional symptoms (intense anxiety or fear) and cognitive symptoms (irrational beliefs about the feared object or situation).
The behaviourist explanation suggests phobias are learned through classical conditioning — associating a neutral object with a frightening experience, so it comes to trigger fear on its own.
Systematic desensitisation gradually exposes a person to a feared object in a controlled, relaxed way, helping them "unlearn" the fear response over time.
