Final answer:
Classical conditioning involves the use of two stimuli to evoke one response. For example, Pavlov's experiment with dogs showed that pairing a bell with food caused the dogs to salivate in response to the bell alone.
Step-by-step explanation:
Classical conditioning involves the use of two stimuli to evoke one response. In this type of conditioning, a neutral stimulus (conditioned stimulus) is paired with an unconditioned stimulus that naturally elicits a response. Over time, the neutral stimulus becomes associated with the unconditioned stimulus and elicits the same response.
For example, Ivan Pavlov's famous experiment with dogs involved pairing the ringing of a bell (neutral stimulus) with the presentation of food (unconditioned stimulus), which eventually caused the dogs to salivate in response to the bell alone.
