Perspective reversal rates and reports of an attribute of apparent depth in a flat stimulus.

Abstract

Os who reported that the 2 equal-sized faces of a Necker cube appeared to be of the same size had significantly lower perspective reversal rates than Os who reported that the “near” face appeared to be smaller than the “far” face. It was suggested that Os who failed to report an apparent size difference may fail to perceive depth in the cube and that this is reflected in their low perspective reversal rates.
