Document Summary
The behavioral approach emphasizes the study of overt (observable) behaviors and the environmental conditions that influence them. Classical conditioning involves pairing stimuli such that an automatic, reflexive response evoked by one of the stimuli comes over time to also be evoked by the pair (previously neutral) stimuli: early animal models of conditioning. Light (cs) + food (ucs) salivation (ucr) Acquisition refers to the process by which a conditioned response comes to exist in the first place. Often takes repeated pairs of the cs and the ucs to gradually becomes stronger and reliable. Discrimination person has discriminated between the two stimuli that are similar. Extinction repeated presentation of the conditioned stimulus without the unconditioned stimulus leads to this: spontaneous recovery a conditioned stimulus is again presented some time after extinction has occurred, the conditioned response may reappear briefly. John watson and rosalie rayner demonstrated human classical conditioning with an 11- month-old boy, little albert.
