Conditioned Inhibition
CSA
+CSB
Definition: A CS signals the absence of an otherwise expected US
Standard Method: Conditioned Inhibition Procedure
CSA
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 .
Common Treatment Phase
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
Notation: A-, BA+

CSUS
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) ?
