Depth Cues of Disparity and Relative Size Added to Necker Cube 1

Abstract

A stereogram was prepared in which one of the alternating facets of the Necker cube was drawn with uncrossed disparity and a reduced size relative to the opposite facet. During a 2-min. stereoscopic viewing period, the disparity cue and reduced-size cue did not affect the number of reversals in depth; however, the depth cues led to the disparate and smaller facet being perceived as more distant for a longer duration than the other facet.
