Question

It is springtime and the pollen from the flowers causes you to sneeze. Soon you are sneezing every time you see a flower even if it is not during pollen season. Using classical conditioning, the US is ________.

Answer 1

The answer is the pollen.

Step-by-step explanation:

In classical conditoning, a conditioned stimulus (the sight of flowers) is associated with an unconditioned stimulus (the pollen). This produces a reaction known as conditioned response (sneezing).

It's important to recognise that unconditioned stimuli are those which naturally produce a response. They can be paired with an unrelated stimulus in order to condition the response.
