Question

in classical conditioning, what is spontaneous recovery? a cr becomes extinct, and after a while the cr reappears in response to a cs. a dog will stop exhibiting a cr out of nowhere, even with reinforcement from a us. a ns will begin producing a ur out of nowhere.

Explanation:

In classical conditioning, spontaneous recovery is when a conditioned response (CR) that has become extinct reappears after a period of time in response to the conditioned stimulus (CS). The other options do not correctly define it. The second option describes an incorrect extinction - like scenario not related to spontaneous recovery, and the third option is about an incorrect and non - existent relationship between a neutral stimulus (NS) and an unconditioned response (UR).

Answer:

A. A CR becomes extinct, and after a while the CR reappears in response to a CS.
