PERCEPTION OF DISTORTION: AN EXPERIMENTAL STUDY OF DISTANCE AND PERSPECTIVE IN THE AMES TRAPEZOID ILLUSION.
Abstract
The research examined various factors which could contribute to the reversal illusion perceived with a rotating trapezoid. Variables included in the study were viewing distance, sex, relation to other reversible figures, and to ellipsoidal figures. Distance directly effects the perception of the illusion from four to twenty feet. A consistent sex difference was found in that males perceive the illusion more than females. A significant correlation was found between perception of the trapezoidal illusion and necker cube reversals. In the comparison of symmetrical and asymmetrical figures, it was found that the unbalanced figures resulted in greater perception of the illusion. There was wide variability among subjects in responding to illusion, suggesting that the perception of the illusion results from many visual cues which result in differential responses. (Author)
