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
Systematic Desensitization
gradually work through increasing fearful stimuli until reaching point
Habituation
decrease in behavioural responding to a repeated stimulus
Sensitization
increase in behavioural responding to a repeated stimulus
Long term potentiation
strengthening of synaptic connections between neurons
Compensatory responses
to protext the body from stimuli that threaten pyschological regulation
- help to maintain body’s homeostasi
why do overdoses occur
the body is unable to maintain homeostasis in a novel environment
- in unfamiliar environments, contingency between body and drug is not present –> body doesn’t produce compensatory responses
TF pairing the US and CS is sufficient for conditioning to occur
False - not sufficient
TF CC generates multiple responses
T
TF CC establishes preferences and aversions
