Answer:

unconditioned stimulus;   conditioned stimulus

Explanation:

In classical conditioning, the unconditioned stimulus is one that initiates a response unreservedly, naturally, and automatically.

One may instantly feel very hungry when you smell one of your favorite dishes. In this instance, the unconditioned stimulus is the aroma of the food.

The conditioned stimulus is a formerly neutral stimulus, which eventually comes to cause a conditioned response after becoming paired with the unconditioned stimulus.
