[Perceived depth produced by luminance differences in the two eyes with zero disparity].
We examined Kaufman, Bacon, and Barroso's (1973) finding that perceived depth covaries with relative luminance of the two half-fields of the stereogram. Five subjects were shown two sets of stereograms: one with three lines and another with random dots. In each trial, they reported the apparent depth plane produced by one of 15 different relative luminances of the lines or the mid portions of the random dots. The direction and the magnitude of perceived depth as a function of the relative luminance varied across subjects. It is argued that the stimulus should be considered as being Wheatstone-Panum's Limiting Case rather than that requires processing of binocular retinal disparity.
