AP PSYCHOLOGY

Detailed explanation-1: -A conditioned stimulus is a stimulus that can eventually trigger a conditioned response. In the described experiment, the conditioned stimulus was the ringing of the bell, and the conditioned response was salivation.

Detailed explanation-2: -Once the neutral stimulus has become associated with the unconditioned stimulus, it becomes a conditioned stimulus (CS). The conditioned response (CR) is the response to the conditioned stimulus. Classical conditioning is learning through association and was first demonstrated by Ivan Pavlov.

Detailed explanation-3: -Eventually, the previously neutral stimulus begins to evoke the same response, at which point the tone becomes known as the conditioned stimulus. The conditioned response in Pavlov’s experiment was salivating in response to the conditioned stimulus.

Detailed explanation-4: -When Ivan Pavlov trained a dog to salivate and expect food whenever it heard a bell, he demonstrated the existence of classical conditioning. This process uses an initially neutral stimulus (a bell ringing) paired with an innate or biological stimulus (food) to elicit an innate response (salivation).
