Abstract
Unambiguous dots (having one binocular disparity) when inserted in an ambiguous random-dot stereogram (with multiple disparity values) could pull the ambiguous percept. The unambiguous bias carried that ambiguous depth percept whose disparity was nearest to the disparity of the bias. The closer the disparities were to each other, the stronger the pulling effect that was observed. Even a physical bias of 4% density was adequate to overcome the natural bias of most observers. The stimulus duration had to be over 50 msec to provide a strong pulling effect. In all experiments the stimulus duration was 160 msec or shorter, indicating that the pulling effect was a product of neural interactions, rather than convergence movement of the eyes. As a result of these findings a parallel model of stereopsis has been proposed, which extends the spring-coupled dipole model of Julesz (1971).
