INDIVIDUAL DIFFERENCES IN SUSCEPTIBILITY TO HYPNOSIS

Abstract
Hypnotic induction was attempted with 40 men and 34 women. The original scoring procedure, following the practice of Friedlander and Sarbin (J. W. Friedlander and T. R. Sarbin, J. Abnormal Social Psychol. 33: 281, 1938.) confirmed their finding of a skewed distribution, with more unsusceptible subjects than highly susceptible ones. When a new scoring scale was adopted based on dichotomized scores for each item, a bimodal distribution resulted. While this scale represented the data better than the original scale, it cannot be asserted with assurance that the distribution of hypnotic susceptibility is bimodal. A significant sex different (p < 0.003) was found, with women more susceptible than men.
