Question

Quizplus · Accepted Answer

Spontaneous recovery is the reappearance of a previously extinguished response (conditioned response, CR) in response to the conditioned stimulus (CS) after a period of rest. It is believed to occur because the extinction process only suppresses the association between the CS and the unconditioned stimulus (US) but does not eliminate it entirely.
