For lack of depth cue, observers are unable to determine rotation direction of these objects in KDE. Moreover, observers perceive the object reversing in rotation direction. Klopfer(1991) used masks of a face as stimulus in his experiment and found that mask appeared to oscillate rather than rotate, because observers are more familiar with convex faces than with concave faces. However, familiarity may not provide a explanation of non-face rotating object in KDE. The purpose of this study is to identify the general factors could explain reversal of rotating masks and non-face objects. We hypothesized that object in KDE reverse while two different depth appearances of a figure changing. A mask is an object with non-homogeneous features, and the homogeneity of an object would influences its reversal number. This study used Necker cubes and masks as stimulus in three experiments to identify the interaction between homogeneity of features, complexity, familiarity, and convex-concave shape would influence the reversal number of an object in KDE. The results of three experiments favor both homogeneity and familiarity of features influence the change of depth appearances.
