Document Summary
Deliberate recall of info that one recognizes as a memory; you can state it in words; consciously putting pieces together to make a story: semantic: facts, episodic: events. Influence of experience on behavior, even if you don"t recognize that influence; not attending to part of brain that"s actually learning it, doing it autonomously: instrumental, operant conditioning: an individual"s response leads to reinforcer or punishment. Reward system must be involved (vta & nucleus accumbens da: associative, classical conditioning: pairing 2 stimuli changes response to one of them. Experimenter presents a conditioned stimulus (cs) which elicits no response, then presents unconditioned stimulus (ucs), which elicits an unconditioned response (ucr), then few pairings of cs & ucs elicit a new, learned conditioned response (cr) Stimulus-stimulus (classical conditioning of fear) formed in thalamus or cortex. Habituation: decrease in response to a stimulus that is presented repeatedly & accompanied by no change in other stimuli.
