Modification of hypnotic susceptibility

Abstract

The purpose of this paper is to demonstrate the effectiveness of a new training procedure on the modification of hypnotic susceptibility. 10 Ss were scored on their objective and subjective performances on the Stanford Hypnotic Susceptibility Scale, Forms A and C, both before and after training. Training consisted primarily of (1) providing the circumstances necessary for a clear conception of the appropriate sensory experiences, (2) allowing S to proceed by self-paced successive approximations, (3) structuring the procedure in order to place S in a double-bind situation, and (4) providing verbal reinforcement and opportunities for S's self-reinforcement. The results indicate that both the objective and subjective post-training changes in hypnotic susceptibility are statistically significant. Ss maintained a significant increase when tested by a new hypnotist, although the scores were slightly but significantly reduced. The increased performance on items not included in the training sessions revealed significant generalization. This investigation provides evidence that hypnotic susceptibility can be modified.
