The purpose of this study is to examine the discrimination sensitivity of binoular disparity with various directing stimuli arranged in surroundings of the fixation point. The stimuli were located at eight directions. The distances from the fixation point to the object were 2, 4, 6, 8deg. When the stimuli were presented at the right and the left directions, individual differences of the discrimination sensitivity were found among subjects. However, the discrimination sensitivities were shifted to the uncrossed disparity in above of the fixation point and shifted to the crossed disparity below of the fixation point. This tendency was same in each subject. These results, such as the asymmetry of discrimination sensitivity in above or below of the fixation point, might be related to the vertical horopter.
