Does the Homo Hypnoticus Exist? Personality Styles of People Interested in Hypnosis.

It may be that individuals who are interested in hypnosis will volunteer for hypnosis experiments or practice hypnosis. Do these "hypnosis-prone" individuals differ from hypno-neutral, nonhypnosis-prone individuals? If so, could one speak of a personality type, the homo hypnoticus? This study reports on 3 samples of individuals where there was no indication of hypnosis or no interest in hypnosis (NONHYP: N = 1426) and 4 samples of individuals who were interested in hypnosis (HYP: N = 1048). Using the Personality Styles and Disorders Inventory, we calculated contrast analyses for the contextual effect of HYP vs. NONHYP and gender effects. Results suggested there may be a homo hypnoticus personality style with the characteristics of intuitive-schizotypal, rhapsodic-optimistic, and charming-histrionic. These distinctions appear mostly in women.
