AP PSYCHOLOGY

Detailed explanation-1: -The increase in responding to the CS following a pause after extinction is known as spontaneous recovery. When Pavlov again presented the CS alone, the behaviour again showed extinction until it disappeared again. Although the behaviour has disappeared, extinction is never complete.

Detailed explanation-2: -Spontaneous recovery refers to the sudden reappearance of a previously extinct conditioned response after the unconditioned stimulus has been removed for some time. This phenomenon can occur after these two types of conditioning have taken place.

Detailed explanation-3: -Pavlov and his classical conditioning experiments found that spontaneous recovery can occur after a period of not being exposed to the Conditioned Stimulus (CS). After a conditioned response has been extinguished, spontaneous recovery gradually increases in strength over time.

Detailed explanation-4: -Spontaneous recovery can be defined as the reappearance of the conditioned response after a rest period or period of lessened response. If the conditioned stimulus and unconditioned stimulus are no longer associated, extinction will occur very rapidly after a spontaneous recovery.
