In Pavlov's famous experiment, the bell was the ________ and the meat was the ________.

• A. UCS; CS
• B. UR; CR
• C. CS; UCS
• D. US; UR

Answer: (C)

The bell becomes a conditioned stimulus because it starts as a neutral signal and, after being repeatedly paired with meat, it comes to elicit a salivation response on its own. The meat is the unconditioned stimulus because it naturally triggers salivation without any learning, and the corresponding reflex is the unconditioned response. Through this association, the bell now produces salivation even without meat, which is the conditioned response. So the bell is the conditioned stimulus and the meat is the unconditioned stimulus.
