A series of tests was devised to assess stereoscopic depth processing, motion parallax depth processing, binocular integration and hand-eye coordination in normal, stereoblind, and stereo deficient subjects. Using a random- dot stereoscopic display viewed through a stereoscope we established that of the 262 subjects tested, 177 were categorized as having normal stereoscopic depth perception, 28 as being stereo deficient and 57 as being stereoblind. These three groups of subjects processed motion parallax information for depth equally well, but the stereoblind and stereo deficient subjects had significantly longer reaction times. On the hand-eye coordination tests the stereoblind subjects performed significantly less well than did normal and stereo deficient subjects, whose performance on these tests was similar. Our binocular integration tests revealed significantly less integration i.. View More»
