CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Extinction is the gradual weakening and disappearance of a conditioned response. Spontaneous recovery is the reappearance of an extinguished conditioned response when the conditioned stimulus returns after a period of absence.

Detailed explanation-2: -Extinction: The gradual weakening and eventual disappearance of a conditioned response.

Detailed explanation-3: -Extinction is the decrease in strength of a learned behavior when the conditioned stimulus is presented without the unconditioned stimulus (in Pavlovian learning), or when the behavior is no longer reinforced (in operant or instrumental learning).

Detailed explanation-4: -The term “extinction” was first used by Ivan Pavlov in reference to his observation that the conditioned response to a cue that predicted food delivery decreased and eventually disappeared when food no longer followed the cue.

Detailed explanation-5: -Extinction and Spontaneous Recovery With extinction, the behavior ceases when the conditioned stimulus is presented, or the behavior becomes sporadic when the stimulus is present. Spontaneous recovery can only happen after extinction and usually follows a rest period where no stimuli are presented.
