Q

how are extinction and forgetting different

A

extinction: active process, omission of an expected US or reinforcer
forgetting: decline of responding that could occur with the passing of time. doesnt require nonreinforcement of the CS/instrumental response

Q

is extinction more like unlearning or a new learning

A

new learning, learning a new rule on top of an old one, light = no food RN, but if it starts again, they remembered

Q

how is extinction used in exposure therapy

A

exposure to cues that elicit fear in the absence of the aversive US

25
in what ways can a return of responding after extinciton come
spontaneous recovery, renewal, reinstatement
26
the decline in conditioned bhv that occurs with extinction ______ with time
dissipates
27
what can cause responding to return after extinction
pause / rest period after training
28
what is the name for a return of responding caused by a pause in extinction training
spontaneous recovery, nothing is done in rest period to produce recovery
29
what is renewal
recovery of conditioned responding when contextual cues from extinction training are changed ex: stop taking drug in therapy/rehab, all ok, but then take them when home
30
in renewal effect, the context can be seen as _______ _____ for reinforcement vs extinction
occasion setter
31
if conditioned in A, extinguished in B, and tested in C what could happen
renewal could appear, renewal is not only due to excitatory effects of A, but absence of B
32
what are the implications of renewal regarding clinical improvement
improvement at therapy may not persist when return in other environment original acquisition learning excitatory effects are generalize more than inhibitory effect of extinction training
33
according to renewal, what can happen with pathological fear
can spread to other contexts
34
which have more widespread effects, problems created by conditioning or solutions/remedies for those problems
the problems if overcome fear, benefit doesnt transfer as easily to new situations
35
what is reinstatement
recovery of conditioned bhv occuring when individual encounters the UCS again
36
when is reinstatement observed
with trauma, drug/relapse
37
explain reinstatement with drugs
free dose of cocaine produces sudden reinstatement of cocaine-seeking
38
T.F. reinstatement with drugs is dose-dependent
T. big dose = big urge for drug-seeking
39
can reinstatement occur in presence of CS, but the absence of UCS
yes, cue-induced reinstatement ex: seeing drug dealer?
40
why does extinction have limited success in treating addiction
cue-induced reinstatement
41
what is one way to enhance extinction in therapy
more extinction trials = more profound decrease in responding
42
what does the pattern of the extinction trials affect
formation and persistence of the memory
43
give an example of massed and spaced trials within session, btw sessions
within: m= every 6 secs ; s= every 600secs btw: m= 100 trials in 1 day ; s= 10trials in 10 days
44
massed and spaced trials give similar effects to those seen with _________
habituation
45
massed of spaced produce more pronounced extinction
mass
46
massed of spaced is more likely to have spontaneous recovery
massed
47
massed of spaced have more enduring extinction
spaced
48
massed of spaced is more immune to recovery
spaced
49
which is more affective in losing the conditioned bhv: extinction immediately after learning or 1 day after
immediately
50
why would extinction be best right after learning conditioned bhv compared to later
interferes with consolidation process
51
what is a risk to using immediate extinction
more likely to have spontaneous recovery and renewal
52
a more enduring loss of bhv occurs if extinction trials are delayed ___________(time) after the acquisition
24hours
53
what is a way to make extinction more pervasive and avoid renewal from lack of generalization
conducted in multiple different contexts = increase stimulus generalization of extinction with large number of spaced trials
54
what is a way to reduce spontaneous recovery
introduce cues present during extinction training to enhance extinction performance
55
where has cues of extinction been used in humans
exposure therapy, reduced renewal of arachnophobia using chip AA as a reminder of treatment context
56
which reinforcement schedual results in fastest extinction
continuous reinforcement - FR1: overtraining extinction effect
57
why extinction paradoxical
need less unreinforced to trials to extinguish than reinforced trial to learn
58
which reinforcement schedule results is slowest extinction
partial reinforcement: unpredictability already includes partial extinction
59
how to get slower extinction and fewer frustration reactions
partial rather than continuous reinforcement partial-reinforcement extinction effect (PREE)
60
what is PREE and what does it help explain
partial-reinforcement extinction effect the bhv of habitual gamblers who persist in gambling even if they encounter a long string of losses
61
T.F. frequent gamblers are less likely to persist during extinction if trained on a partial reinforcement schedule
F. more likely
62
how are partial reinforcement effects observed in pavlovian conditioning
cues paired with uncertain reward probability and size = more attractive + more likely to produce reinstatement
63
what makes slots machines stimulating
lights and sounds increase urge to play and inflate perception of wins
64
partial reinforcement increases the chances that someone will become a _______
sign-tracker, also reduces the rate at which cues undergo extinction
65
what are the names of the two theories that explain partial reinforcement
frustration theory and sequential theory
66
what is frustration theory
repeated experience of frustration of non-reward during training increases resilience
67
what is sequential theory
when a sequence of non-reinforced trials are followed by reward, it reinforced the persistence when the reinforcement is absent
68
which partial reinforcement theory is most correct
both complete each other
