What were the criticisms for Pavlov's dog?

Criticisms of Pavlov's dog experiments primarily revolve around their oversimplification of complex behaviors. Critics argue that the classical conditioning model fails to account for cognitive processes and emotional responses, reducing learning to mere stimulus-response associations. Additionally, some researchers have pointed out ethical concerns regarding animal welfare in experimental settings. Overall, while Pavlov's work laid the groundwork for behaviorism, it has been challenged for its limitations in explaining the full range of learning and behavior.
