Posthypnotic amnesia, the hidden observer effect, and duality during hypnotic age regression

Dissociative and hypnotic experiences in eating disorder patients: an exploratory study

Hypnotizability, subjective experiences during hypnotizability assessment, and dissociation were studied in 53 eating disorder patients in order to explore the relationship between these phenomena. Dissociation was measured with a newly developed self-reporting Dissociation-Questionnaire (DIS-Q), level of hypnotizability was assessed with the Stanford Hypnotic Clinical Scale (SHCS), subjective experiences during hypnosis with the Dutch Phenomenology of Consciousness Inventory (DPCI), and the Dutch Resistance to Hypnosis Scale (DRHS). Compared with normals, eating disorder patients scored significantly higher on the DIS-Q and SHCS. Compared with restricting anorexics, anorexics of the mixed type as well as bulimics report higher scores on both the DIS-Q and SHCS, but a significant difference was found only for the DIS-Q subscale loss of control. Although positive correlations between the DIS-Q and SHCS were found, the magnitude of the correlations shows that both instruments probably are measuring different constructs. Some implications of these findings are discussed.

The hidden observer, hypnotic dreams, and age regression: clinical implications

This article summarizes data from three studies (Maré, Lynn, Kvaal, Segal, & Sivec, in press; Lynn, Maré, Kvaal, Segal, & Sivec, 1993) designed to extend research on the "hidden observer" to two phenomena of clinical relevance: hypnotic dreams and suggested age regression. Subjects received suggestions for a hypnotic dream or age regression and then received suggestions for a "hidden observer" (i.e., the subject possesses a part of the self that is aware of images and ideas that the conscious mind is unaware of) with respect to the dream or age-regression experience. Hidden reports contained more personally relevant information than the target suggestions (i.e., dream, age regression). Subjectives were also less likely to recall hidden reports. The high rate of hidden-observer responding (> 80%) was also evident in nonhypnotized simulating and relaxed subjects, although they did not exhibit as much primary process thinking in their dream reports as hypnotized subjects. Case studies of a trauma client and a forensic client are used to illustrate the clinical potential of hidden-observer suggestions.
