Extinction
Cards in this deck (28)
- 1Who has done the most work on extinction?Bouton
IT CAN RELAPSE
IT IS NEW LEARNING - 2What are the two main effects of extinction?1. the rate of respondin decreases
2. response variability increases - OC (try once doesn't work , next time try something a little diff) - 35 ways relapse occursspon recov
rapid reacquisition
resurgence
renewal
reinstatement - 4Rapid ReacquisitionCan be faster than intial acquisition
(think of muscle memory) - 5Operant Extinction leaves two options?Give up
Try some toher means --) reinforcement - 6CE two meaningsCS -) US excite
CS --) no US inhibitory
OPPOSING FORCES
Look for context clues to discern - 7Positive expectancy Negative expectancyacquired durin reinforcement
acq during non-reinforcement
They determine this via the environment
e.g. cats bowl can be either food or nothing
which will be positive exp or negative exp - 8ResurgenceOnly for operant behaviours
Regression of earlier behaviours that got u the reward in the past
e.g. sniffy does other behaviour like sitting in certain places in which previous generated the food - 9What causes resurgence? e.g.?Contextual cues create an expectation of the chance to make the response and receive reinforcement.
You go out clubbing and have a few drinks rememebr the past and want to take pingas - 10What are the issues from a clinical perspective ?Spon is something reappears while undergoin extinction
Where as resurgence is bheaviour that reappears from something that was reinforced in the past - 11Extinction burst? e.g.Happens early in exitinction leads to a increase and intensity in responding - leads to rage u start kicking the vending machine
- 12Extinction side effectsIncrease variability - u may change the way u perform the task.
Think about ur key when it doesnt work.
Basically creates a new behaviour - 13Neuringer study on extinctionShowed response rates decrease and variability in types of repsonsesi ncrease
- 14Amsel and Roussel finding On Frustration being energisingFrustration --) drives behaviour they remove food from a box and they found the rats run faster
- 15More Ex side effectsFrustration --) aggression
- 16ResistanceAnother side effect
More training --) more resistance
Persistent repsonding = high res
Respond stops quickly = low resistance to ex - 17Factors of resisHistory
Magnitudge
Delay
Degree
Previous exp - less res
Distinctive signal - less resis - 18Is Context very important in CC and why?Yes it is because its multisensory , diffuse and continuously present
- 19What are the type of context?Spatial - configuation of object
Temporal context - time related e.g. thoughts we had
Interoceptive - hormonal and physiological states - huger, stress drugs
Cognitive - perceive / interept current situations - 20Social and Cultural contexts ?Social nextwork , social settings
- 21Renewal and resinstaement seen most in CCRenewal occurs in context ... if they are put in a novel context the fear conditioned repsosne will come back (in any other context other than the extinction context will renew fear)
Ext - is specific to context (inhibits) it took place - 22ReinstatementExtinguished fear reinstates when unsginalled presentation of the US
CONTEXT SPECIFIC based on where the US occured (SAME US CONTEXT) - 23Why does context play such an important role?Followin ext tendancy to con respond is always on ...
unless they in the ext context then it can be turned off - 24Why is extinction more context dep than conditioning?Because its learned second ...
learning and mem system treats first association as context free. - 25Nelson reversed the order and found?Its not inhibitory that is context speciic but the order it was learned
- 26How do we reduce spon recovery?Repeat periods of rest and testing
Manipulate interval btw acq and ext
fear con - less spon rec with shorter intervals
Appetitive cond - was the opposute
Present cues associated with extinction - 27Reducing renewal?conduct extinction in mutiple settings
- increase stimulus generalisation - 28—
