Inhibitory Conditioning � Excitatory conditioning involves predicting the US from a CS. � Inhibitory

Inhibitory Conditioning � Excitatory conditioning involves predicting the US from a CS. � Inhibitory conditioning involves predicting the absence of the US from a CS.

Inhibitory Conditioning � Measuring conditioned inhibition - Summation test

Inhibitory Conditioning � Measuring conditioned inhibition - Summation test Acquisition A+ US B+ US

Inhibitory Conditioning � Measuring conditioned inhibition - Summation test Acquisition A+ US B+ US AX- Test BX- nothing If responding to BX- is lower than B+ from the outset of the test phase, then X- is said to be a conditioned inhibitor.

Inhibitory Conditioning � Measuring conditioned inhibition - Retardation of acquisition test

Inhibitory Conditioning � Measuring conditioned inhibition - Retardation of acquisition test

Inhibitory Conditioning � Measuring conditioned inhibition - Retardation of acquisition test Acquisition A+ US

Inhibitory Conditioning � Measuring conditioned inhibition - Retardation of acquisition test Acquisition A+ US B+ US AX- Test X+ US Y+ US nothing If X developed conditioned inhibition during the acquisition phase, then it should take longer to acquire responding to X than Y during the test phase.
