IMAGERY AND HYPNOTIZABILITY REVISITED

The objective of this study was to correlate computer-generated imager y tasks and a self-report measure of imagery ability with hypnotizabil ity, hypothesizing that computer-generated imagery tasks would be bett er predictors of hypnotizability than will the self-report measure. Hy pnotizability of 43 subjects was assessed using the Hypnotic Induction Profile and the Stanford Hypnotic Susceptibility Scale, Form C. Image ry ability was assessed by the Visual Vividness Imagery Questionnaire (VVIQ) and by computer-generated imagery tasks measuring the ability t o generate, maintain, and transform images. Although there was no corr elation between the VVIQ and hypnotizability, the less hypnotizable su bjects made twice as many mistakes in the spatial imagery tasks than d id the more hypnotizables, but this difference was not statistically s ignificant. The relationships among hypnotic performance, hypnotizabil ity, and imagery functions are complex.
