This research investigated whether any correlation exists between self-attention and a response to a visual perceptual illusion. Self-attention was defined to include both the dispositional trait of self- consciousness and the situational state of self- awareness. Perceived reversals of geometric figures were the specific illusion response of interest. Subjects were classified as high or low in private self-consciousness on the basis of a self- report questionnaire. Half of each self- consciousness group was randomly assigned to a condition designed to increase self-awareness. Subjects passively viewed two geometric figures, the order of which was counterbalanced for each group and condition, and reported perceived reversals within a specified time period. The data were analyzed in terms of a 2 x 2 multivariate analysis of variance design to determine the effects of dispositional and/or situational self- attention upon the frequency of perceived reversals. The results indicated no relationship between individual differences in self- attention (either dispositional or situational) and individual differences in susceptibility to visual illusions. Reported reversals for each stimulus were highly correlated. There were no gender differences in the mean number of reported reversals.
