classical conditioning
Term | Definition |
---|---|
Association | A learned connection between two (or more) objects or events - especially significant in classical conditioning. |
Aversion therapy | A form of treatment using classical conditioning to cause an undesired behaviour to create an unwanted response, thereby reducing the incidence of the behaviour. |
Classical (Pavlovian) conditioning | Reflexive response elicited by previously neutral stimulus through repeated association. |
Extinction | When a response no longer occurs - in classical conditioning, when the conditioned stimulus is presented several times after the unconditioned stimulus has been withdrawn. |
Flooding | Actual exposure of patient to feared stimulus at a level greater than usual. |
Graduated exposure | A form of treatment using gradually increasing levels of fear-provoking stimuli paired with induced relaxation, thereby reducing the incidence and level of phobic reaction to the stimulus. |
Learning | A relatively permanent change in behaviour due to experience. |
Neutral stimulus | The name given to the conditioned stimulus before it becomes conditioned. It is referred to as a neutral stimulus while it fails to produce a response. |
Spontaneous recovery | The reappearance of an extinguished response after a rest period. |
Stimulus discrimination | When an organism responds to the conditioned stimulus but not to any stimulus which is similar to the stimulus. |
Stimulus generalisation | When an organism responds to a stimulus that is similar to the conditioned stimulus. |
Unconditioned (reflex) response | The response that occurs automatically when the unconditioned stimulus is presented. The UCR is a reflexive or involuntary response as it is predictably caused by an unconditioned stimulus. |
Unconditioned stimulus | Any stimulus which consistently produces a particular naturally occurring automatic response (e.g. the food in Pavlov's experiments). |
