Classical Conditioning Flashcards
classical conditioning
associate 2 related events
- learning of contingency b/w a particular signal and a later event paired in time/space
- preparatory in nature & promotes survival
contingencies
when one stimulus reliably predicts the presentation of another
Unconditioned stimulus
stimulus or event triggered in the absence of learning
unconditioned response
response after us
- occurs naturally
conditioned stimulus
previously neutral stimulus that becomes associated with US to trigger response on its own
Conditioned response
response that occurs once contingency b/w cs and us are learned
Aquisiton
process by which contingency b/w CS and US are learned
- amount learned in later trials do not match amount learned at beggining
- some contingencies acquired in single trial
Extinction
loss of CR when CS no longer predicts US
Spontaneous Recovery
sudden recovery of CR following rest period after extinction
- presence of CS will elicit CR once again
learned, inhibitory contingency competes with original learned response
Stimulus Generalization
stimulus similar to the CS will also elicit a CR
- adds flexibility and efficiency to classical conditioning
Stimulus Discrimination
restricts range of CS that can elicit a response
- refines learning process –> builds compelx responses for adaptive environment
CS +
presence of biological stimulus
CS -
absense of biological stimulus
predicts absence os US and elicits no UR
CS paired w/absence of US in order to elicit no UR or corresponding CR
What happens if CS+ and CS- are presented at the same time
shows intermediate response
Implosive therapy
confront CS that invokes anxiety using their imagination
