In classical conditioning, ___________________________ happens when a stimulus is no longer paired with an unconditioned stimulus.
Explanation
Answer: C - In classical conditioning, extinction happens when a stimulus is no longer paired with an unconditioned stimulus. For example, if the smell of food (the unconditioned stimulus) had been paired with the sound of a whistle (the conditioned stimulus), it would sooner or later come to induce the conditioned response of hunger. However, if the conditioned stimulus (the whistle) was no longer teamed with the unconditioned stimulus (the smell of food), eventually the conditioned response (hunger) would vanish.
