II. CLASSICAL CONDITIONING /People (and animals) acquire certain behaviors through classical conditioning /Learning process II. CLASSICAL CONDITIONING /People (and animals) acquire certain behaviors through classical conditioning /Learning process in which associations are made between an unconditioned stimulus and a neutral stimulus.

STIMULI /Something that elicits a response. /NEUTRAL STIMULUS: / Initially does not elicit a STIMULI /Something that elicits a response. /NEUTRAL STIMULUS: / Initially does not elicit a response. /UNCONDITIONED STIMULUS (UCS): /UNCONDITIONED RESPONSE (UCR): /elicits a predictable response w/o training. automatic or natural reaction to a stimulus w/o training /

Taking classical conditioning a step further GENERALIZATION: Responding to a second stimulus similar to Taking classical conditioning a step further GENERALIZATION: Responding to a second stimulus similar to the original CS / DISCRIMINATION: the ability to respond differently to different stimuli ✏ EXTINCTION: When the CR gradually dies out after the CS is repeatedly presented w/o the UCS /SPONTANEOUS RECOVERY: When the CR reappears after a rest period following extinction. ✏

Cognitive Processes Early behaviorists believed that learned behaviors of various organisms could be reduced Cognitive Processes Early behaviorists believed that learned behaviors of various organisms could be reduced to mindless mechanisms. (cognition in rats and dogs does not play a role) Rescorla and Wagner (1972) disagreed /Experimented with rats using tone, light (sometimes), and electric shock /Rats feared the tone, but not the light, even though the light was always followed by a shock.

Cognitive Processes, cont. /Treating alcoholics with classical conditioning /Lace alcohol with nausea inducing drugs Cognitive Processes, cont. /Treating alcoholics with classical conditioning /Lace alcohol with nausea inducing drugs /Patient knows to blame the nausea on the drug, not the alcohol /Similar treatment has had limited success

Biological Predispositions Early researchers believed that the laws of learning were basically the same Biological Predispositions Early researchers believed that the laws of learning were basically the same in all species. (any natural response could be conditioned to any neutral stimulus) Each species has predispositions that prepare it to learn the associations that enhance its survival. /Rats develop taste aversions to poisoned bait /Birds (that hunt by sight) develop aversions to the sight of tainted food /Humans develop taste aversions to novel foods after getting sick. (not the restaurant, plates, people, or music)
