This paper presents a model of how binocular single vision can be achieved. The model incorporates an inhibitory mechanism into the fusion theory, so we call it binocular‐inhibition theory. The essential property is an inhibitory mechanism in which a binocular unit yielding a fused image might inhibit two monocular neural units yielding double images in the network. To test the validity of the theory, we manipulated the binocular unit strength in the binocular network and measured the cumulative disappearance times of a monocular test stimulus in Panum's limiting case and in a single‐line stereogram under fixation of the eyes. We found that the test stimulus in a single‐line stereogram disappeared for longer periods of time than in Panum's limiting case. These results support the validity of the binocular‐inhibition theory, assuming that the inhibitory effect on the monocular units might be directly proportional to the activity of the binocular units and that binocular single vision can be achieved using the inhibitory effects from a binocular unit to monocular units.
