Behaviour Therapy

Direct answer
Behaviour therapy is the application of learning theory — classical conditioning from Pavlov and operant conditioning from Skinner — to treat psychiatric disorders by modifying maladaptive learned behaviour rather than exploring unconscious conflict. Its principal techniques are systematic desensitisation (gradual paired exposure with relaxation, based on reciprocal inhibition), flooding and implosion (prolonged high-intensity exposure), aversion therapy (pairing the unwanted behaviour with an unpleasant stimulus), and operant methods such as positive and negative reinforcement, punishment, shaping, token economy and modelling. Phobias, obsessive-compulsive disorder, enuresis, addictions and behavioural problems of children and intellectual disability are its classical indications.
What you must remember
- Systematic desensitisation (Wolpe): construct an anxiety hierarchy, train deep muscle relaxation, then pair relaxation with graded exposure — the principle is reciprocal inhibition, since anxiety and relaxation cannot coexist.
- Flooding and implosion: immediate prolonged exposure to the most feared stimulus until anxiety extinguishes — flooding uses real stimuli, implosion imagined scenes; faster but distressing, and contraindicated in cardiac disease, epilepsy and pregnancy.
- Exposure and response prevention: the specific technique for obsessive-compulsive disorder — contact with the feared object while blocking the compulsion until anxiety habituates.
- Aversion therapy: pairs the behaviour with an aversive stimulus — the disulfiram-alcohol reaction chemically, or mild electric aversion historically for paraphilias; covert sensitisation uses imagined unpleasant consequences.
- Operant toolkit: positive reinforcement (reward to increase behaviour), negative reinforcement (removing aversives to increase behaviour), punishment, extinction, shaping, token economy (tokens exchangeable for rewards, used in chronic schizophrenia wards) and modelling (Bandura's observational learning).
- Other named techniques: progressive muscle relaxation (Jacobson), assertiveness and social skills training, contingency contracting, and habit reversal for tics and trichotillomania.
- Exam indications: phobias (desensitisation or flooding), OCD (exposure and response prevention), enuresis (buzzer alarm), alcohol dependence (disulfiram aversion) and behaviour programmes in autism and intellectual disability.
Common confusion
Negative reinforcement versus punishment is the eternal slip: negative reinforcement removes something unpleasant to strengthen a behaviour (as when compulsive handwashing briefly relieves contamination anxiety, thereby reinforcing the compulsion), whereas punishment adds or removes something to weaken a behaviour. Systematic desensitisation versus flooding is the second discriminator — gradual hierarchy with relaxation versus immediate maximal exposure. Finally, behaviour therapy changes behaviour through conditioning without analysing thought content, which distinguishes it from cognitive behaviour therapy; both, however, use exposure.
Exam-focused takeaway
NEET-PG asks behaviour therapy as technique-matching: snake phobia answered by systematic desensitisation with reciprocal inhibition, compulsive rituals by exposure and response prevention, drinking by disulfiram aversion, and ward motivation in chronic schizophrenia by token economy. One-liners credit Wolpe (desensitisation), Skinner (operant conditioning), Bandura (modelling) and Jacobson (relaxation), and test the flooding contraindication list. Expect definition stems on reinforcement types where negative reinforcement is deliberately worded to look like punishment.
Frequently asked questions
What is systematic desensitisation?
Wolpe's graded exposure up an anxiety hierarchy paired with relaxation, based on reciprocal inhibition.
How does flooding differ from desensitisation?
Immediate prolonged exposure to the most feared stimulus, skipping hierarchy and relaxation; faster but poorly tolerated.
What is the difference between negative reinforcement and punishment?
Negative reinforcement removes an unpleasant stimulus to increase a behaviour; punishment decreases behaviour.
What is a token economy?
Desired behaviours earn tokens exchangeable for rewards, used in chronic psychiatric wards.
Which behavioural treatment is specific to obsessive-compulsive disorder?
Exposure and response prevention until anxiety extinguishes.
What is aversion therapy?
Pairing the unwanted behaviour with an unpleasant stimulus, classically the disulfiram-ethanol reaction.
