Psychiatry: basic sciences
Learning theory & behavioural psychology
Learning theory explains how behaviour is acquired and changed through experience, including classical and operant conditioning and observational learning. It is the foundation for behavioural treatments of anxiety, phobias, OCD and addiction.

What is it?
Learning theory comes from experimental psychology. Pavlov showed that a neutral signal can come to trigger a response when paired with something meaningful (classical conditioning). Skinner showed that behaviour followed by reward tends to be repeated, and behaviour followed by punishment or no reward tends to fade (operant conditioning).
Bandura added that people also learn by watching others (social or observational learning). Together these ideas explain how fears, habits and addictions can form, and how they can be unlearned.
Psychiatrists use these principles directly in exposure therapy, behavioural activation for depression, contingency management in addiction and behavioural programmes for children and people with intellectual disability.
Why does a psychiatrist need it?
Many effective psychological treatments are built on learning principles. A psychiatrist who understands conditioning can explain why avoidance keeps anxiety going, why reassurance-seeking feeds OCD, how cravings are triggered by cues in addiction, and how to design simple behavioural plans with families and ward teams.

Common questions
How can conditioning explain a phobia?
A frightening experience can link a situation with fear. Avoiding that situation then brings relief, which reinforces the avoidance, so the fear never gets a chance to fade. Exposure therapy works by breaking that cycle gradually.
Is learning theory still relevant today?
Yes. It remains the basis of exposure therapy, behavioural activation and contingency management, all of which have good evidence. Modern approaches combine it with cognitive models.
