Document Summary

Pavlov was greatly influenced by darwin"s on the origin of species and believed that conditioning is the basis for how animals learn to adapt to their environments. Acquisition: gradual formation of an association between the conditioned and unconditioned stimuli. Contiguity: critical element in the acquisition of a learned association is that the stimuli occur together in time. Further evidence showed that the strongest conditioning occurs when there is a brief delay between the cs and the us. Extinction: a process in which the conditioned response is weakened when the cs is repeated without the us. Spontaneous recovery: a process in which a previously extinguished response re emerges following presentation of the cs. Stimulus generalization: adaptive process that occurs when stimuli similar, but not identical to the cs produces the cr. Stimulus discrimination: a differentiation between 2 similar stimuli when only one of them is consistently associated with the us and the other is not.
