Question

In Pavlov's early classical conditioning experiments, food was the __________, and a bell which was originally a neutral stimulus became a __________ when paired with the food.

Answer 1

The answer is unconditioned stimulus and conditioned stimulus, respectively.

Step-by-step explanation:

In classical conditioning, a conditioned stimulus (the sound of the bell) is associated with an unrelated consequence, called unconditioned stimulus. This produces an involuntary reaction called conditioned response.

The unconditioned stimulus is usually related to physiological needs, such as food or the avoidance of pain.
