Learning: change in behavior or resulting from experience: classical conditioning: we learn to anticipate/prepare for significant events, operant conditioning: (aka instrumental) we learn to repeat acts that bring good results and avoid those that bring bad. Classical (associative) conditioning (pavlov: unconditioned stimulus (ucs): stimulus that elicits reflexive response in the absence of learning (meat, unconditioned response (ucr): reflexive response elicited by ucs (salivation, neutral stimulus: sti(cid:373)ulus that does(cid:374)"t eli(cid:272)it refle(cid:454)ive respo(cid:374)se (cid:894)tone(cid:895) Problem: ranchers in western us wolves & coyotes eat sheep. Lamb meat (ucs) satisfaction for wolves (ucr) Classical conditioning links simple involuntary responses to neutral stimuli. Meat + drug (ucs) nausea (ucr) [lamb meat (cs) nausea (cr): more complex behaviors are voluntary, they operate on environment to produce rewarding/punishing stimuli, the responses are instrumental in obtaining a reward/punishment. Law of effect: thorndike, future frequency of a response is related to its past consequence, reinforcement increases response while punishment decreases it.
