mechanisms and theory- rescorla & wagner

Question 1

Which effects do Rescorla & Wagner have a theory ?

Answer 1

Overshadowing

Blocking

Un-blocking

Over expectation Loss of associative value ↓ - despite pairing with US!

Conditioned inhibition

Extinction of conditioned excitation

Protection from extinction

extinction conditioned inhibition

NOT:
latent inhibition!

Question 2

Which theories have a problem of Rescorla and Wagner?

Answer 2

Extinction of inhibition - Does not go the way they predicted.

Extinction of excitation - not unlearning! not opposite of acquisition

CS can actually have inhibitory and excitatory properties

Latent inhibition - Can not be explained by RW model!

Unblocking through weaker US > is not shown by R-W but is possible

Question 3

Which theories do Pierce and Hall have?

Answer 3

aquisition

blocking

latent inhibition

unblocking

Question 4

what are the theories of Miller - Comparative model?

Answer 4

excitatory

overshadowing

blocking

Retrospective revaluation

unblocking / unovershadowing

extinction of inhibition

backwards blocking

post aquisition strengthening conext = not proven
