week 3 Flashcards
classical conditioning
delayed conditioning
CS onset precedes US onset
trace conditioning
CS is presented and terminated prior to US onset
simultaneous conditioning
CS and US are presented together
backward conditioning
US is presented and terminated prior to CS
temporal conditioning
there is no CS, but the US is presented at regular intervals. Over time the CR occurs just prior to the onset of the US
limitation present CS/US only
does not control for sensitization in experimental group
limitation explicitly unpaired
could induce learning itself; inhibitory learning (CS predicts non-occurence of US)
limitation truly random presentation of CS/US
By accident same trials as experimental group
preparedness
some stimuli are easier to associate with a given US than others
types of responses that can be conditioned
- responses of the autonomous nervous system
- skeletal responses
- motivational/emotional responses
- cognitive responses
retardation test
CS- is paired with US (you see a delayed establishment)
summation test
CS+ and CS- are presented together (prevents CR from CS)
Spontaneous recovery
reoccurence of CR after empty time interval
renewal
reoccurence of CR after change of context
reinstatement
reoccurence of CR after experiencing US alone
disinhibition
reoccurence of CR after presenting a new stimulus
Mackintosh attentional model
once an animal has identified a cue that reliably predicts a specific event, it attends only to the predictive stimulus and ignores other stimuli that are not essential
comparatory model
animals learn about all CS/US relationships. Some CS/US may not be expressed when there is a CS/US association that is stronger
rescorla-wagner model overshadowing
salient stimulus acquires associative strength more readily than nonsalient stimulus
rescorla-wagner model blocking
associative strength to blocking stimulus prevents conditioning to blocked stimulus
rescorla-wagner model predictiveness
a more predictive stimulus accrues more associative strength than does a less predictive stimulus
comparator theory overshadowing
conditioning to salient stimulus is stronger than to nonsalient stimulus
comparator model blocking
conditioning is stronger for blocking than for blocked stimulus
attentional model overshadowing
salient stimulus more associable than nonsalient stimulus
