Ivan Pavlov

Ivan Pavlov was a Russian physiologist whose work on classical conditioning had a profound impact on psychology. His experiments with dogs demonstrated how neutral stimuli could become associated with reflexive responses, providing the basis for behavioral learning theory. While Pavlov was primarily a physiologist, his findings were adopted by behaviorists like John B. Watson and B.F.

Skinner to explain human behavior. His work remains a fundamental concept in psychology, essential for understanding how associations are formed and how behavior can be modified through environmental conditioning.
