Which psychologist is best known for classical conditioning experiments with dogs?

• A. Ivan Pavlov
• B. B. F. Skinner
• C. Albert Bandura
• D. Jean Piaget

Answer: (A)

Classical conditioning shows how an association forms between a neutral stimulus and a naturally signaling stimulus. The best-known demonstration comes from Ivan Pavlov, who studied how dogs learn to anticipate food. He started with a natural, unconditioned stimulus—food—that reliably triggers an unconditioned response—salivation. By pairing a neutral stimulus, the sound of a bell, with the presentation of food, the bell began to predict the food. After several pairings, the dogs salivated in response to the bell alone, showing a conditioned response. The bell had become a conditioned stimulus, and the learning that occurred is called acquisition. This work established how a neutral cue can come to elicit a reflexive response through association.

Other researchers are linked to different learning ideas: B. F. Skinner is known for operant conditioning, emphasizing behavior shaped by consequences; Albert Bandura for observational or social learning; Jean Piaget for stages of cognitive development.
