Retinal disparities which produce perceived depth in stereoscopic vision result from configurational differences in the retinal images in the two eyes of objective three-dimensional arrangements. Experiments reported earlier demonstrated special effectiveness of differences in the alignment in the vertical dimensions of the images of points that are at different depth. Here a stereoscopic experiment is reported where alignment differences were increased without altering disparity. An increase in perceived depth resulted and was measured by estimation and by matching. The reason for the special effectiveness of binocular alignment differences is discussed.
