classical conditioning
unconscious/automatic learning
associative learning
learning that certain events occur together
ivan pavlov
studied classical conditioning, used dogs in experiments
unconditioned stimulus (UCS)
automatically triggers some type of response
ex: loud noise makes u jump, stubbing toe -> wincing
unconditioned response (UR)
automatically triggered by exposure to unconditioned stimulus
ex: loud noise makes u jump, stubbing toe -> wincing
neutral stimulus
stimulus elicits no response before conditioning
* ringing bell before introducing meat -> no response bc not associated with meat yet
pairing neural stimulus with unconditioned stimulus
neural stimulus can elicit the same response as unconditioned stimulus, becomes associated
conditioned stimulus (CS)
a neural stimulus paired with unconditioned stimulus that now triggers automatic response -> association
* dog learns to associate bell with meat -> bell = conditioned stimulus
conditioned response (CR)
learned, automatic response to once neural but now conditioned stimulus
* bell gets associated with meat, dog’s mouth will water just by sound of bell
extinction
diminishing of conditioned response, when a unconditioned stimulus doesn’t follow a conditioned stimulus
* ringing bell without meat will eventually cause the dog’s mouth to not water
spontaneous recovery
reappearance of weakened conditioned response after a rest period
* ringing the bell after a little while of not ringing it will cause the dog’s mouth to start watering again
generalization
stimulu similar to conditioned stimulus elicits similar responses
* dog conditioned to sound of one tone also responsed to new and different tones
discrimination
ability to distinguish between conditioned stimulus and similar stimuli that aren’t associated with unconditioned stimulus
* dogs learned to respond to a sound of a specific tone and not other ones
