Further norms on the harvard group scale of hypnotic susceptibility,form A

The Harvard Group Scale of Hypnotic Susceptibility, Form A was administered to 168 upper level college students. Findings are congruent with the original normative data reported by Shor and E. C. Orne. Differences between the two samples' mean scores and distributions are discussed in terms of sample composition. Further support for the group scale as an accurate predictor of hypnotic susceptibility was indicated by a significant relationship between the group scale and the individually-administered Stanford Hypnotic Susceptibility Scale, Form C.
