Abstract
Since the recent development of the Stanford Hypnotic Susceptibility Scales, researchers have been provided a means of investigating crucial problems in the area of hypnosis. This study investigates the applicability of the reported norms to a population which differs from the normative sample. “True volunteer” dental students were found to score well above the “volunteer” normative sample due mainly to the reduced percentages of low hypnotic susceptibility Ss. The effects of schooling, volunteering, and implications concerning the relationship between personality and hypnotic susceptibility in the volunteer sample are discussed.
