Measurement Problem

CR actively inhibited = no CR

True Inhibition

Lack of excitation = no CR

Lack of Excitation

Retardation and Summation Tests

The Experimental Group receives inhibitory training with CSB .

The Control Group receives no training with CSB .

Conditioned Inhibition

Why Does the Experimental Group Learn More Slowly?

0

Excitation

Inhibition

+

-

Tendency to Salivate to CSB

The Control Group starts at 0.

Going from Trial 1 to Trial 5, the level of excitation increases.

Conditioned Inhibition

Why Does the Experimental Group Learn More Slowly?

0

Excitation

Inhibition

+

-

Tendency to Salivate to CSB

The Experimental Group starts below 0.It takes extra trials to bring them up to 0, then more trials to raise the level of excitation.

Summation Test

Group Treatment Excitor Test ResultInhibition A+, AB- T+ TB- crControl A+, AC- T+ TB- CR

Logic:Inhibition: T + B = 1 + -1 = 0Control: T + B = 1 + 0 = 1

Conditioned Facilitation

Definition: CSA signals the US only in the presence of CSB

S-R Theory

Nature of Conditioning

Question: Does the CS evoke an “expectation” of the US (S-S) or does the CS directly elicit the CR (S-R) ?
