Abstract

Our previous study indicates that the small binocular disparity can cause the depth perception in the longer distance, but not in the shorter distance (Sato, Shindate & Shigemasu, 1999). This result suggests that the threshold for disparity detection would depend on the viewing distance. In this study, we investigated whether or not the disparity detection threshold depends on convergence, which is a low level cue for distance estimation. It is found that the disparity detection is significantly more sensitive at the smaller vergence angle (262 min) than at the larger vergence angle (524 min). This result suggests that the sensitivity to binocular disparity is modulated by convergence. This hypothesis is supported by the physiological study (Trotter, 1995).
