He is renowned for his work in classical conditioning, demonstrating how animals could associate a neutral stimulus with a reflexive response through repeated pairings

This famous psychologist and scientist is Ivan Pavlov. He conducted experiments in the late 19th and early 20th centuries that led to the discovery of classical conditioning. Pavlov found that dogs could be conditioned to associate the sound of a bell with the anticipation of food. Through repeated pairings of the neutral stimulus (the bell) with the reflexive response (salivation), the dogs began to salivate in anticipation of food when they heard the bell alone, even when no food was present. This groundbreaking research demonstrated the power of associations and laid the foundation for understanding learning and behavior in both animals and humans.
