John G. Watkins is a United States psychologist best known for his work in the areas of hypnosis, dissociation, and multiple personalities. With his wife, Helen Watkins, he developed ego-state therapy, which uses analysis of underlying personalities rather than traditional talk therapy to find the causes of psychological problems.
The most famous example of the use of ego-state therapy was the interrogation of the Hillside Strangler, in which Watkins solicited a confession by revealing the killer’s multiple personalities.[1]
Watkins is a graduate of the University of Idaho and holds a Ph.D. from Columbia University. He is professor emeritus at the University of Montana, where he taught for many years.
