Unit 3 - learning & development Flashcards
(83 cards)
classical conditioning
involuntary learning by association of stimuli
acquisition
a neutral stimuli becomes associated with an unconditioned stimulus to trigger a response (classical conditioning)
UCS
UCR
CS
CR
UCS - unlearned stimulus, triggers an automatic response
UCR - natural, unlearned response
CS - neutral stimulus that is repeatedly paired with UCS
CR - learned behavior in response to a CS
extinction
gradual disappearance of a CR when the CS is no longer paired with the UCS
spontaneous recovery
random appearance of a CR after a period of extinction
generalization
tendency to have a CR to stimuli that are similar to the CS
discrimination
ability to differentiate btwn a CS and similar stimuli
higher order conditioning
an already established CS is paired with a new neutral stimulus to elicit the CR
counterconditioning
behavior therapy technique where a negative/undesirable response is replaced with a positive response
taste aversion
developing a dislike to food after having a negative experience with it
one-trial conditioning
when one pairing of stimuli results in a CR
biological preparedness
idea that organisms are predisposed to quickly learn associations w/ certain stimuli that enhance survival
habituation
decrease in response to a repeated stimulus
operant conditioning
learning process with rewards or punishments that follow behavior
positive reinforcement
adding a desirable stimulus after a behavior to increase that behavior
negative reinforcement
removing an undesirable stimulus after a behavior to increase that behavior
positive punishment
adding a negative stimulus after a behavior to decrease that behavior
negative punishment
removing a positive stimulus after a behavior to decrease that behavior
shaping
teaching through successive approximations (rewarding increasing closer steps)
instinctive drift
tendency for a learned behavior to gradually revert to biologically predisposed patterns
continuous reinforcement
reinforcement for every correct behavior
partial reinforcement types
-fixed-ratio: pattern based on # of responses
-variable-ratio: no pattern, based on # of responses
-fixed-interval: pattern based on time
-variable-interval: no pattern, based on time
cross-sectional study
study of diff aged people at one point in time
longitudinal study
studies the same people over time
