Document Summary
P101 lecture 17 notes- learning from experience (cont. ) Conditioned taste aversion- special kind of classical conditioning; some kind of event/bad experience causes repulsion in future. Eat something that makes you sick sight alone of that food elicits sick feeling. Can be acquired through observation of someone else getting sick. Food in itself not problematic, but experience strongly influences physical response. Highly adaptive mechanism- things that make us sick can be dangerous. Stimulus generalization- new stimulus (similar to conditioned stimulus) elicits response just like conditioned stimulus would. Little albert (1920: early instance of stimulus generalization, being studied by john watson (behaviorism, used classical conditioning to make him afraid of rat. At first, did(cid:374)"t (cid:373)i(cid:374)d letti(cid:374)g rat (cid:272)ra(cid:449)l o(cid:374) hi(cid:373) Then gave him rat and hit loud gong- startle response formed association between rat and gong: generalized fear to other animals and things- rabbit, fur coat. Stimulus discrimination- responding differently to new, similar stimulus than to conditioned stimulus.
