Using modeling and information to modify hypnotizability

Abstract

Ss were 117 college students divided into 3 groups. 1 group observed a model being reinforced for hypnotizable behavior, 1 observed a model being punished for hypnotizable behavior, and the third did not observe a model. Previously, each S had completed 1 of 3 randomly-distributed programmed learning texts containing facilitative information about hypnosis, non-facilitative information, or information unrelated to hypnosis. Hypnotizability was subsequently determined by the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHSA) of Shor and E. Orne (1962). Significantly higher HGSHSA scores were obtained from Ss exposed to the reinforced model than from Ss exposed to the punished model. Facilitative information yielded higher HGSHSA scores than nonfacilitative or unrelated information. No interaction effects were obtained. In order for individuals to obtain maximum hypnotic responsiveness, it is desirable that members of the general population not be exposed either to hypnotic Ss being punished or ridiculedand that non-facilitative statements be avoided. Facilitative information presented in a programmed-learning-text format may be a useful technique for enhancing hypnotizability.
