Imagery and hypnotizability revisited.
The objective of this study was to correlate computer-generated imagery tasks and a self-report measure of imagery ability with hypnotizability, hypothesizing that computer-generated imagery tasks would be better predictors of hypnotizability than will the self-report measure. Hypnotizability of 43 subjects was assessed using the Hypnotic Induction Profile and the Stanford Hypnotic Susceptibility Scale, Form C. Imagery ability was assessed by the Visual Vividness Imagery Questionnaire (VVIQ) and by computer-generated imagery tasks measuring the ability to generate, maintain, and transform images. Although there was no correlation between the VVIQ and hypnotizability, the less hypnotizable subjects made twice as many mistakes in the spatial imagery tasks than did the more hypnotizables, but this difference was not statistically significant. The relationships among hypnotic performance, hypnotizability, and imagery functions are complex.
