Five experiments were conducted to examine the interaction between alternative disparities, using several simple stereograms consisting of a few identical vertical lines. The cumulative time of stereopsis-disappearance was measured. It was found that the time of stereopsis-disappearance increased, (a) as the disparity increased in the single line condition (local stereopsis), (b) as the lateral separation between two lines decreased in the Panum's limiting case as well as in the 2 line condition (global stereopsis), (c) as the difference of disparities increased in the 2 line condition, or (d) when the test line was in the middle rather than in the sides in the 3 line condition. These results can be consistently explained by supposing the inhibitory effects from the false targets to the true targets, inversely proportional to the distance between them, in the binocular network.
