Document Summary
Change in an organism"s behaviour/ thought as a result of experience. Process of responding less strongly over time to repeated stimuli. Responding to something better after being exposed to it before. Form of learning which animals respond to a previously neutral stimulus that had been paired with another stimulus that elicits an automatic response. Ucs- stimulus that elicits an automatic response. Ucr- automatic response to a nonneutral stimulus that does not need to be learned. Animal does not need to learn to salivate. Response previously associated with a nonneutral stimulus that elicited by a neurtal stimulus through conditioning. Initially neutral stimulus that comes to elicit a response due to association with an unconditioned stimulus. Pavlov noted that classical conditioning occurs in 3 phases, acquisition, extinction and spontaneous recovery. Learning phase during which a conditioned response is established. Closer cs and ucs the faster learning occurs. Gradual reduction & eventual elimination of the cr after the cs is presented repeatedly.
