Binocular Depth Perception in Man — A Cooperative Model of Stereopsis

Abstract: Under ordinary conditions the world appears very similar to us whether we view it with both eyes or one eye alone. Except for a slight increase in plasticity — owing to stereopsis (stereoscopic depth perception) — the contours and textures of objects seem unchanged. Because of this similarity between the monocular and binocular views it was commonly believed that understanding binocular vision must await the understanding of monocular vision. What is more, since the binocular percept exhibits an attribute — three-dimensionality — that is missing in the left and right vertical projections, it was widely accepted that seeing with two eyes is more complex than seeing with one eye. For example Sherrington (1906), the leading physiologist of his time, concluded “that during binocular regard … each uniocular mechanism develops independently a sensual image of considerable completeness. The singleness of binocular perception results from union of these elaborated uniocular sensations.” This opinion prevailed (and became even more exaggerated by the Gestaltist school) until the invention of random-dot stereograms in 1959.
