title: Dissociation and displacement: where goes the "ouch?".
abstract: Hypnosis is widely used to relieve pain. Current theory emphasizes its dissociative features. Multiple personality patients can eliminate pain in the primary personality by displacing it into underlying alters. The Hilgards demonstrated that normal hypnotized subjects can similarly dissociate pain into a covert cognitive structural system which they called the "hidden observer." The Watkins discovered that "hidden observers" appeared to be the same phenomenon as "ego states." "Ego-state theory" assumes that human personality develops through integration and differentiation. At one end of the continuum, "differentiation" is adaptive. Ego states possess relatively permeable boundaries as in normal moods. At the other end ego-state boundaries become less permeable. Normal "differentiation" becomes maladaptive "dissociation" and multiple personalities may be created. In the intermediate range of the differentiation/dissociation continuum, "covert" ego states can be found in many normal subjects who volunteer for hypnotic laboratory experiments. Normal individuals, like multiple personalities and "hidden observer" subjects, can displace (dissociate) pain into "covert" ego states. The pain is not eliminated. This suggests that when we remove pain by hypnosis we may not be getting away "scot-free."
