The disappearance of dichoptically presented real and subjective contours
The fragmentation characteristics of luminous figures set off by real or subjective contours were studied under dichoptic viewing conditions. Dichoptically viewed subjective contours fragmented in a manner quantitatively and qualitatively similar to that previously obtained with binocular viewing. The number of fragmentations for real contour analogues increased substantially under dichoptic relative to binocular conditions. These results are considered to support the view that subjective contours arise primarily from central processes within the perceptual system.
