Detection and processing of vertical disparity by the human observer
Gerald Westheimer, Mark W. Pettet · Proceedings of the Royal Society B Biological Sciences · 1992
Based on the distinction between uniocular vertical magnification and vertical disparity, the induced size effect experiments were reinterpreted and new experiments done to show that vertical disparity signals can produce other stereoptic depth effects. The direction and efficiency of utilization of vertical disparity signals depend on the quadrant of the visual field and the stimulus position within it.
