Question

Pavlov noticed that dogs began salivating at the mere sight of the person who regularly brought food to them. For the dogs, the sight of this person had become a(n): conditioned response (CR). conditioned stimulus (CS). neutral stimulus (NS). unconditioned stimulus (US).

Answer 1

The answer is (CS) conditioned stimulus.

Step-by-step explanation:

Conditioned stimulus is a stimulus that makes the organism react to something associated to something else. In this case it made the dogs salivating at the sight of the person that brought them food because that person was the person that fed them.

In order for CS to happen, it requires repeated stimulation over time.
