Grayson’s dog salivates whenever he hears the refrigerator door open because he is accustomed to receiving food each time anyone opens it. Grayson tries an experiment with his dog. Over the next few days, Grayson does not give his dog any food when he opens the refrigerator door, even though he knows the dog expects it. As a result, the dog stops salivating when the refrigerator door is opened. Grayson’s dog’s behavior best illustrates in classical conditioning.

The answer is extinction.

Explanation:

Extinction refers to the gradual disappearance of the response to a stimulus. This usually occurs when the unconditioned stimulus is removed. In the example, the dog has stoppped receiving the food, so he stops responding to the conditioned stimulus (the sound of the door).

Sometimes, an extinct response can sudddenly reappear. This is called spontaneous recovery.
