Unit 4 Flashcards
Learning
learning
process of acquiring new and relatively enduring information/behavior through experience
classical conditioning
links two stimuli so 1st stimulus elicits behavior in anticipation of 2nd stimulus
operant conditioning
learning which behavior to repeat/avoid for reward or to avoid unwanted results
cognitive learning
learn things we’ve never experienced through observation/language
habituation
decreased responsiveness with repeated exposure to stimulus
associative learning
learning that certain events occur together
respondent behavior
behavior occurring as AUTOMATIC response to stimulus
operant behavior
behavior that operates on the environment producing consequences
neutral stimulus NS
a stimulus that elicits no response before conditioning
unconditioned response UR
unlearned naturally occurring response to an unconditioned stimulus
unconditioned stimulus US
stimulus that unconditionally (naturally + automatically) elicits unconditioned response
conditioned response
learned response to a previously neutral (now conditioned) stimulus
conditioned stimulus CS
originally neutral stimulus that’s now associated with US to trigger CR
acquisition
initial stage of conditioning where NS is linked with US to trigger CS //behavior is linked to consequence
higher order conditioning
(/second order); a CS is paired with a new NS creating 2nd weaker CS
Extinction
the diminishing of a CR when no longer followed by US // when behavior is no longer paired with reinforcer
spontaneous recovery
the reappearance of an extinguished CR after a pause
generalization
tendency for stimuli similar to CS to elicit similar responses to CR // learned response occurs in similar situations
discrimination
learned ability to distinguish between a CS amd similar stimulus that doesn’t signal US // distinguish between reinforced vs not reinforced response
law of effect
having followed by favorable consequences are more likely to recur those followed by unfavorable consequences less likely (THORNDIKE)
operant chamber
(/Skinner box) chamber containing bar/key for animal to manipulate to obtain reinforcer; attached devices record animals bar/key interactions
reinforcement
any event that STRENGTHENS the behavior it follows
shaping
operant conditioning procedure; reinforcers guide toward closer approximation of desired behavior
discriminative stimulus
stimulus that elicits response after association with reinforcement (vs stimuli not associated with reinforcement)
positive reinforcement
INCREASING behavior by ADDING a desired stimulus
