What limitations did later scientists identify in Ivan Pavlov’s theories about mental illness?

While Ivan Pavlov’s work established a foundation for the scientific analysis of behavior, later scientists identified several limitations in his theories regarding mental illness and higher mental activity.

Clinically, critics have noted that Pavlov uncritically accepted contemporary psychiatric views on conditions such as schizophrenia and paranoia. Many modern psychiatrists now consider his explanations of these disorders to be too limited. Furthermore, while Pavlov applied neural concepts like induction and irradiation to explain higher mental activity, these frameworks are no longer viewed as sufficient by many contemporary experts.1

In the broader field of biological psychology, many neurophysiologists have shifted their focus toward more modern developments, such as electrophysiology and biochemistry, to better understand the physiological bases of behavior and mental disorders. Additionally, Pavlov’s philosophical approach was criticized for failing to clearly define the separation between subjective mental phenomena and the objective scientific methods he insisted upon using to measure them.12
