Quizplus · Accepted Answer

The conditioned stimulus (CS) in Pavlov's principle experiment was the tone. During the experiment, the dogs learned to associate the sound of the tone with the arrival of the meat powder, which was the unconditioned stimulus (UCS). Eventually, the tone alone was enough to elicit a conditioned response (CR) of salivation, even without the presence of the meat powder.
