psych chapter 6 Flashcards
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
