Trance logic and cue structure as supplied by the hypnotist.

Logically incongruous behavior was elicited in contexts that varied appreciably in the extent to which they cued Ss as to appropriate trance logic response. Independent sets of hypnotically responsive and unresponsive Ss were assigned to a real or simulating condition in application of the real-simulating model of hypnosis and tested under 1 of 2 cue conditions (high and low). These conditions either clearly communicated the hypnotist's intent regarding trance logic response (high cue) or did not (low cue). It was hypothesized that real and simulating Ss would be differentiated when optimal conditions for testing were maintained, that is, under the low-cue condition where intent was not communicated obviously. Data for 107 highly selected undergraduates challenge the validity of the double hallucination index as an adequate measure of trance logic but show high discriminative value for the transparency index. Detailed analysis of the behavior of both groups of Ss indicated distinctive properties of experience that highlighted the complex nature of hypnotic Ss' cognitive controls.
