Thirty-six subjects were matched with respect to hypnotic suggestibility and divided into three treatment groups hypnotic analgesia, hypnotic simulating, and control. The subjects were given semantic differentials on which to rate the words ache, pain, discomfort, tingling, pressure, and numbness. The subjects then immersed their hands in water at 0 deg C and rated the pain experienced on a five-point scale ranging from just noticeable to intolerable. No significant differences were found among the groups on the semantic differential data, but there were significant differences in the maximum immersion times for the various groups. The hypnotic analgesia group had the longest immersion time, the hypnotic simulating group was second, and the control group had the shortest immersion time. The pain scales were essentially linear for all groups. Author
