U6: Learning Flashcards
learning
relatively permanent or stable change in behavior as a result of experiences
non associative learning
occurs when an organism is repeatedly exposed to one type of stimulus
two types: habituation and sensitization
habituation
learning to “tune out” a stimulus
dishabituation
after a person has been habituated to a given stimulus, and the stimulus is removed, to the person is no longer accustomed to the stimulus when it returns
sensitization
an increase in responsiveness due to either a repeated application of a stimulus or a particularly aversive or noxious stimulus, the stimulus produces a more exaggerated response
desensitization
a decreased responsiveness to an aversive stimulus after repeated expose (desensitization therapy)
classical conditioning
occurs when a neutral stimulus paired with a previously meaningful stimulus, eventually takes on some meaning itself
neutral stimulus has to come before the unconditioned stimulus
conditioned stimulus (CS)
initially the neutral stimulus
unconditioned stimulus (US)
the initially meaningful stimulus
unconditioned response (UR)
the unlearned response to the unconditioned stimulus, the naturally occurring response
conditioned response (CR)
response to CS after conditioning
forward conditioning
when the CS is presented before the US
delay conditioning
CS is presented until the US begins
trace conditioning
CS is removed some time before the US is presented
John Watson’s Little Albert
classical conditioning, albert was conditioned to fear a rat
generalization
inability to distinguish different stimuli
discrimination
ability to distinguish different stimuli
aquisition
when the pairing of the natural and neutral stimuli have occurred with enough frequency that the neutral stimulus alone will elicit the conditional response
extinction
the elimination of the conditioned response, can be achieved by presenting the CS without the US repeatedly
