Final Test-9

Question 1

Classical Extinction

Answer 1

reduction of learned response occurs because CS is no longer paired with US

Question 2

Instrumental Extinction

Answer 2

reduction of instrumental response occurs because response is no longer reinforced

Question 3

Effects of Extinction (Responding, Behavioural, Emotional)

Answer 3

Responding: decreases, measure rate of extinction
Behavioural Effects: decrease responding
Emotional Effects: frustration/aggression

Question 4

Spontaneous Recovery

Answer 4

occurs after extinction of instrumental response if tested after delay period

Question 5

Renewal of Original Excitatory Conditioning

Answer 5

Recovery of excitatory responding to extinguished stimulus produced by shift from contextual cues of extinction process (extinguish fear in one context, still present in others

Question 6

Reinstatement of Conditioned Excitation

Answer 6

Recovery of excitatory responding to an extinguished stimulus produced by exposures to US

Question 7

Resurgence of Conditioned Behaviour

Answer 7

Reappearance of an extinguished target response when another reinforced response is extinguished

Question 8

Enhancing Extinction: number and spacing

Answer 8

increased extinction trials and closer together most effective

Question 9

Conducting Extinction in Multiple Contexts

Answer 9

increase impact of extinction by conducting extinction in a variety of contexts (reduce renewal)

Question 10

Compound Extinction Stimuli

Answer 10

Present 2 stimuli simultaneously that are both being extinguished

Question 11

Priming Extinction to Update Memory for Reconsolidation

Answer 11

Presenting CS can activate memory of acquisition of a conditioned response; once activated, this memory is modifiable

Question 12

Inhibitory SR Associations

Answer 12

suggests that nonreinforcement results in SR association (organism not reinforced for S when responding); responding (R) suppressed whenever S present

Question 13

Paradoxical Reward Effects

Answer 13

should get more rapid extinction after training that establishes greater expectation of reward

Question 14

Overtraining Extinction Effect

Answer 14

less persistence of instrumental behaviour in extinction following overtraining

Question 15

Magnitude Reinforcement Extinction Effect

Answer 15

less persistence of instrumental behaviour in extinction following training with large reinforcer

Question 16

Partial Reinforcement Extinction Effect (PREE)

Answer 16

greater persistence in instrumental responding in extinction after partial reinforcement training; extinction slower, fewer frustrative responses

Question 17

PREE: Discrimination Hypothesis

Answer 17

extinction slower after partial reinforcement; partial reinforcement teaches persistence

Question 18

Sequential Theory

Answer 18

Assumes can remember recent reward/nonreward trial, memory of nonreward becomes cue for performing response, results in persistence in extinction
