Habituation vs inhibitory learning

Question 1

Habituation hypothesis

Answer 1

Extinction through habituation, causing desentization. Doesn’t involve new learning, and is vulnerable for spontaneous recovery, reacquisition in different contexts (renewal) reinstatement (unsignaled US) and re-acquisition

Question 2

Inhibitory learning model

Answer 2

Original CS-US association learns is not erased, but secondary inhibitory learning about this assoc. develops. (no longer predicts US). Not focused on fear reduction during exposure, but expectancy violation

Question 3

Meanings of CS after extinction

Answer 3

CS-US; original meaning

CS-no US; additional inhibitory meaning

Question 4

Reason for fear

Answer 4

Anxious people have deficits in mechanisms central for extinction learning. Also contribute to development of excessive fear. The fear is a mismatch between expectancy and outcome. The more this expectancy can be violated, the greater inhibitory learning

Question 5

Expectancy violation

Answer 5

Needs to be very specific in order to word. As learning is focused on whether the expected negative outcome occured. Learning is consolidated by asking to judge what they learned regarding non-occurrence. Mental rehearsal is important for memory reconsolidation

Question 6

Error-correction models

Answer 6

salience of the CS

Question 7

Deepened extinction

Answer 7

Multiple fear CSs are extinguished seperately and than combined. Eg combining internal and external CS that predict the same US

Question 8

Occasional reinforced extinction

Answer 8

Occasional CS-US parings combined with CS-no US parings
