Question

Quizplus · Accepted Answer

In Pavlov's initial classical conditioning studies, a tone (or bell) was used as the conditioned stimulus (CS) to elicit a conditioned response (CR) of salivation in dogs. The unconditioned stimulus (UCS) was the presentation of food, which naturally caused the dogs to salivate (unconditioned response - UCR). Over time, the tone became associated with the presentation of food, and eventually, the tone alone could elicit salivation in the dogs (now a conditioned response - CR). So, the CS was the tone, not the dog, salivation or food.
