Pavlovian Extinction

The fading of a conditioned response when the signal keeps appearing without the expected event.
What it is
Mark Bouton's 2004 review of the extinction literature argues that extinction does not erase the original learning but adds new learning that depends strongly on context, so the setting in which extinction happened matters to whether the response stays quiet.
In effect
In the article on classical conditioning, it explains why a learned response that has faded is not simply gone.
What it does not say
It does not say that a faded response will always return, and it sets no fixed time for extinction to take.
