HYPNOSIS, HYPNOTIC PHENOMENA, AND HYPNOTIC RESPONSIVENESS: Clinical and Research Foundations-A 40-Year Perspective.

The authors summarize research findings, their clinical implications, and directions for future research derived from 40 years of study of hypnosis, hypnotic phenomena, and hypnotic responsiveness at Steven Jay Lynn's Laboratory of Consciousness, Cognition, and Psychopathology and Joseph P. Green's Laboratory of Hypnosis. We discuss (a) the accumulating body of evidence that hypnosis can be used to advantage in psychotherapy; (b) the fact that hypnosis can facilitate a broad array of subjective experiences and suggestions; (c) the failure to find a reliable marker of a trance or radically altered state of consciousness and reservations about conceptualizing hypnosis in such terms; (d) determinants of hypnotic responsiveness, including attitudes and beliefs, personality traits, expectancies, motivation, and rapport; (e) efforts to modify hypnotic suggestibility; and (f) the need to further examine attentional abilities and the role of adopting a readiness response set that the authors argue is key in maximizing hypnotic responsiveness.
