- A form of psychotherapy used to reduce or avoid an undesirable behaviour pattern.
- Aim is to condition the patient to associate the undesirable behaviour with an undesirable stimulus.
- This leads to a suppression of the behaviour.

- At the same time they are engaging in the undesirable behaviour.
- The unpleasent stimulus is the unconditioned stimulus.Tis produces an unconditioned response(being sick.)
- When the unpleasent behaviour is repeatedly paired with th UCS the behaviour becomes conditioned.
