Abstract

Two expetiments were conducted to examine the validity of the fusion theory, the suppression dveory, and the Wolfe's model of stereopsis. In the first experiment. dichoptic stimuli having no interocular counterpart were presented to the subjects in order to test the necessity of fusion as an essential prerequsite for stereoscopic depth perception. In the second experiment, dichoptic stimuli designed to activate only rivalry pathway but not stereoscopic pathway in the Wolfe's model were presented to the subjects to test whether suppression could 6e a necessary condition for binocular single vision. Results of the experiments show that first, subjects perceive depth in the stimuli which have not interocular counterpart. Second, subjects perceive depth in the stimuli that activate only the rivalry pathway. The results imply that fusion is not a prerequisite for the depth perception, that unlike the assumption of Wolfe's model rivalry pathway is not independent of stereopsis pathway and finally that binocular rivalry does not always occur.
