| Abstract: | Assigned 70 female student nurses to 1 of 3 treatment conditions: hypnotic induction, instructions to simulate hypnosis, or imagination control. All Ss were assessed on M. Orne's (see record 1960-05341-001) 2 indexes of trance logic (the transparent and the double hallucination). The imagination controls consistently showed trance logic as often as the hypnotic Ss. Depending upon the stringency of the criterion for hallucination, the simulating Ss showed trance logic less often, as often, or more often than the hypnotic Ss and the imagination controls. In the 2nd phase of the investigation, 6 simulating Ss consistently manifested trance logic as often as 5 highly selected "somnambulistic" hypnotic Ss. Since trance logic was not found to be a discriminating characteristic of hypnotic Ss, investigators who seek the "essence of hypnosis" must now search elsewhere. (25 ref.)
