Document Summary
Learning- a process by which experience produces a relatively enduring change in an organism"s behaviours and characteristics. Fixed action pattern- and unlearned response automatically triggered by a particular stimulus. Habituation- is a decrease in the strength of response to a repeated stimulus over time. Classical conditioning- organisms learn to associate two stimuli, such that one stimulus comes to produce a response that originally was produced only by the other stimulus. The example of pavlov"s dog: unconditioned stimulus (ucs)- no learning is required to produce salivation, unconditioned response (ucr)- salivation, conditioned stimulus (cs)- tone, conditioned response (cr)- salivation. A reflexive, unlearned response to an innately important stimulus. A response elicited by a stimulus whose importance depends on past learning. Feeling hungry when you see your favourite restaurant. Extinction- cs is presented repeatedly in the absence of ucs. Spontaneous recovery- the reappearance of a previously extinguished cr after a rest period. Stimulus generalization- stimuli similar to the initial cs elicit a cr.
