Q

What are the two tests for inhibition?

A
  1. Summation test - S reduces responding to another CS+
  2. Retardation test - subsequent learning of an S-US is impaired; takes a very long time to learn those previous negative relationships are now positive ones (going from thinking that they are inhibitors to encouraging a response); they are not just starting from a neutral position.

Q

What is conditioned inhibition?

A

Learning that a CS prevents the reward; therefore there is not point responding to it.

Negative discrepancy - the stimulus becomes an inhibitory because the associative strength becomes negative.

Q

Two different types of associative connection:

A

Excitatory link primes memory of the US.

Inhibitory link suppresses memory of US.
