Classical Conditioning Ivan Pavlov studied digestion in dogs; described Cla ssical Conditioning , involving: UCS (unconditioned stimulus) stimulus that pro duces automatic/unlearned/reflexive response. UCR (unconditioned response) stimulus that pr oduces automatic/unlearned/reflexive response t o a UCS that occurs without learning. CS (conditioned stimulus) initially neutral stimul us, becomes associated with the UCS. CR (conditioned response) learned response. Pavlovs Classical Conditioning Model P235 By virtue of CS-UCS pairing, the CS come s to elicit the CR, a response closely relate d, but not identical, to the UCR. Aversive Conditioning classical condition ing to an unpleasant UCS. Avoidance response Acquisition learning phase during which a CR is established. Extinction gradual decrease and eliminat ion of the CR when the CS is presented re peatedly without the UCS. Acquisition and Extinction P236 Spontaneous Recovery sudden reemergence of an extinguishe d CR after a delay....
