Hypnotic hallucination alters evoked potentials.

The use of fast extracted mid-latency auditory evoked potentials monitoring to improve the measurement of the hypnotic component of anesthesia

EEG P300 event-related markers of hypnosis.

Barabasz, Barabasz, Jensen, Calvin, Trevisan, and Warner (1999) showed that, when subjects are stringently selected for hypnotizability and responses are time locked to events, robust markers of hypnotic responding emerge that reflect alterations in consciousness that correspond to subjects' subjective experiences of perceptual alteration. To further test the Barabasz et al. (1999) hypothesis, ...

Neurophysiological Correlates of Hypnotic Analgesia

This short review describes recent advances in understanding hypnotic modulation of pain. Our current understanding of pain perception is followed by a critical review of the hypnotic analgesia studies using EEG, evoked potential and functional imaging methodologies.

Artifact in the "essence of hypnosis": an evaluation of trance logic.

In Phase I of the investigation, 70 5s were assigned to one of three treatment conditions: hypnotic induction, instructions to simulate hypnosis, or imagination control. All 5s were assessed on Orne's two indexes of trance logic (the transparent hallucination and the double hallucination). The imagination controls consistently showed trance logic as often as the hypnotic Ss. Depending upon the ...

The efficacy of the Waterloo-Stanford Group Scale of hypnotic susceptibility: form C.

This study explored whether the Waterloo-Stanford Group Scale of Hypnotic Susceptibility Form: C (WSGC) approximates the predictive power of the individually administered Stanford Hypnotic Susceptibility Scale: Form C (SHSS: C). Seventy-one undergraduates were administered the WSGC in a group setting and then tested individually on the SHSS: C. The participants were then hypnotized and tested o...
