This study deals with the disappearance of the half-occluded region that is the monocular region made by occlusion. The disappearance of the half-occluded region was suggested by the data shown in Shimojo and Nakayama's (1990) Experiment 1. In this article, to investigate the disappearance of the half-occluded region, three experiments were conducted. Following effects were found: (a) depth in stereopsis was seen while the half-occluded region was disappearing, (b) the disappearance of the half-occluded region was due to interocular suppression, i.e., binocular rivalry. Finally, the author discussed what mechanism sets off binocular rivalry and how binocular rivalry is escaped in the half-occluded region.
