The word “psychology” literally means the scientific study of the mind, or psyche. A little over a century ago, psychologists were in fact avidly studying the mind, mental life, and the subjective experience of self. The most brilliant psychologists of the era – most prominently William James and Robert Woodworth – were assembling knowledge of a broad range of phenomena, pulling together concepts that cast light upon the relationship between subjective experience and overt behavior. Some – for example Ivan Pavlov and Edward L. Thorndike – were actively involved in the study of animal experience, as reflected in their behavior.

Psychologists of that era were examining evidence that the mind is not a single agent but consists of a collection of semi-independent “mini personalities” that operate much as a social system operates. To illustrate, “automatic writing” experiments provided intriguing insights into the subconscious mind and the potential existence of subsystems of personality.

Overall, these experiments suggested that automatic writing could access subconscious thoughts and emotions, supporting the idea that personality consists of multiple subsystems. This early research laid the groundwork for later studies in psychology and psychoanalysis.

Then something strange happened. American psychology abruptly abandoned the study of the psyche altogether. A new breed of psychologists closed their eyes to everything except overt behavior, pointedly refusing to discuss mind or subjective experience any further. These were the “behaviorists,” and they took over the science of psychology for more than 25 years.

How could psychology, the study of the psyche, refuse to study the psyche? Noted theorist Bernard Baars commented upon the odd intrusion of behaviorist concepts into psychology. Baars wrote, “A harsh critic might see the twentieth century as a time of lost opportunities. Psychologists could have built on the magnificent foundation of James’s Principles (1890/1983)—by wide consent the greatest psychological work in English. Instead, they chose to evade some of the most fundamental aspects of human existence.”

Finally, serious scientists have resumed the study of the mind, reclaiming the essence of psychology. And yet scientific psychology continues to suffer from what we might call a “behaviorist hangover.” What's that? It's the lasting impact of the behaviorist movement on modern psychology, even though the movement's peak influence waned decades ago.

In this podcast Deep Divers Mark and Jenna turn their attention to this issue in a lively discussion based on Tom Whitehead’s upcoming book, Reimagining Psychology.
