psych chapter 6 Flashcards
(53 cards)
reflexes
a motor or neural reaction to a specific stimulus in the environment
learning
the process of acquiring through experience new & relatively enduring information or behaviors
John Locke & David Hume
echoed Aristotle, we learn, first, by association, our minds naturally connect events
habituation
decreasing responsiveness with repeated exposure to a stimulus
associative learning
learning that certain events occur together, the event may be two stimuli or a response & its consequence
stimulus
any event or situation that evokes a response
respondent behavior
occurs as an automatic response to some stimulus
operant behavior
operates on the environment, producing consequences
Ivan Pavlov
Russian scientist, best known for research on dogs & experiments in classical conditioning
classical conditioning
a process by which we learn to associate stimuli & consequently to anticipate events
unconditioned stimulus (UCS)
stimulus that elicits a reflective response in an organism
unconditioned response (UCR)
a natural (unlearned) reaction to a given stimulus
neutral stimulus (NS)
stimulus that does not naturally elicit a response
conditioned stimulus (CS)
stimulus that elicits a response after repeatedly being paired with an unconditioned stimulus
conditioned response (CR)
behavior caused by the conditioned stimulus
Moisha
diagnosed with cancer, she vomited every time after her chemotherapy treatments & after the remission of her cancer and she still had doctors appointments she would get nauseous when at the office
higher-order conditioning
pairing a new neutral stimulus with the conditioned stimulus (second-order conditioning)
acquisition
when an organism learned to connect a neutral stimulus & an unconditioned stimulus
Garcia & Koelling
rat study involving flavor/illness & light-sound/illness, flavor/illness group learned to avoid the flavor
Robert Rescorla & Alan Wagner
mathematical formula to calculate probability that association is learned given the ability of a conditioned stimulus predicting the occurrence of an unconditioned stimulus & other factors (Rescorla-Wagner model)
extinction
the decrease in the conditioned response when the unconditioned stimulus is no longer presented with the conditioned stimulus
spontaneous recovery
the return of a previously extinguished conditioned response following a res period
stimulus discrimination
when an organism learned to respond differently to various stimuli that are similar
stimulus generalization
when an organism demonstrates the conditioned response to stimuli that are similar to the conditioned stimulus
