Abstract

The objective of this study was to investigate the depth representation for a bilaterally processed binocular stimulus. In the first experment, the magnitude of perceived depth was measured to see whether the stereoscopic depth would vary systematically as a function of the sign and magnitude of binocular disparity. In the second experiment, the stereoscopic depth of a bilaterally processed stimulus was compared with that of a unilaterally processed stimulus to test the effect of fusion or the resolution of depth, results show that perceived depth of a bilaterally processed stimulus change as a monotonic function of its binocular disparity although it produce double images. When a monocular stimulus was unilaterally presented, the subject perceived it as being farther than referential fixation point regardless of the target position relative to the fixation point, and the perceived depth of the target was maximum when it was located near the fixation point. In conclusion, the result implies that our visual system must have a certain nonfusional stereopsis mechanism which can correctly represent the depth of a bilaterally processed object in 3-dimensional space.
