Document Summary
Classical conditioning: simplest mechanism; the relationship bw 2 stimuli is learned about so that future behaviour is changed. Capitalizes on predictable sequence of events in the environment; if one stimulus reliably precedes another stimulus, then these two stimuli can become associated. Pavlov recognized that salivation response used to study how associations are formed bw external stimuli in the environment + nervous system. Vul"fso(cid:374) studied salivary response of dogs when various substances were placed in the mouth. Snarskii looked at salivary response to artificial substances: black water experiment. Object learning dogs were learning to associate a visual feature of water. Classical conditioning procedure involves two kinds of stimuli a(cid:374)d the su(cid:271)je(cid:272)t"s responses to each of the stimuli: unconditioned stimulus (us) Presenting this would elicit a response w/o any learning at all biologically relevant stimuli (i. e. food) Unconditioned response (ur: conditional stimulus (cs, response to us. Would not elicit too much of response when presented the first time.
