Cue Deflation

The process where a cue that previously signaled the availability of a reinforcer loses its value or effectiveness after the reinforcer is decreased or removed.

Potentiation

The enhancement of a conditioned response (CR) to a nonsalient stimulus when a salient stimulus is also paired with the unconditioned stimulus (UCS).

Acquisition of Extinction

The process in conditioning when the conditioned response is reduced and eventually disappears as the conditioned stimulus is no longer paired with the unconditioned stimulus.
