VISUAL-PERCEPTION OF AREA AND HYPNOTIC-SUSCEPTIBILITY

The visual perception of area of geometrical figures was compared for subjects of high and low hypnotizability in experiments with direct co mparison of two different geometrical figures: The Stanford Hypnotic S usceptibility Scale (Form C) was used to assess subjects' hypnotizabil ity. No differences between 17 highly hypnotizable and 10 low hypnotiz able subjects were found. Present results were also compared with thos e previously obtained for subjects of unknown hypnotizability. The mod el based on the Image Function Theory proposed earlier to explain the errors in area estimation committed by subjects of unknown hypnotizabi lity was confirmed as a general rule.
