In Pavlov's "salivating dogs" studies, the salivation triggered by the sound or tone was the ________________
A) conditioned stimulus
B) unconditioned response
C) conditioned response
D) unconditioned stimulus
Answer: C
Rationale: A conditioned response (CR) is the learned response that occurs to the conditioned stimulus (CS). Pavlov's dogs famously learned to salivate to a once neutral sound, making salivation the CR. In contrast, the salivation in response to the food was the unconditioned response (UR), because the dogs did not have to learn this reflexive response.
