ringing a bell, connecting to object
unconditioned response
drooling of dog, response to unconditioned stimulus
elicited
provoke
classical conditioning
dog example, based on associationism
extinction
when the dog unlearns the habit of salivating for the bell
spontaneous recovery
a stronger association, testing once more for the unconditioned response
instrumental conditioning
learning based on consequence
skinner
rats
thorndike
cats
law of effect
behavior is controlled by consequences, and is a choice
disciminate stimulus
something tells you its available ex: smoking
stimulus reinforcement
consequences
positive reinforcement
something received after response that increases liklihood that you'll do it again ex: don't smoke and you get a cookie
punishment reinforcement
response that decreases possibility of behavior
ex: smoke and you'll get detention
negative reinforcement
increased liklihood of behavior

not changing bahavior
ex: get paid for # of t-shirts
varied ratio
slot machine- could be next pull to make it big
fixed interval
salary - get paid once a month
varied interval
