Central integration effects with stabilized afterimages

Prolonged patterned afterimages were used to study integration effects in stabilized images. Seven Ss were presented with various configurations of a pattern through a prism stereoscope, both monocularly and binocularly. Some of the fragmentations and regenerations reported in the binocular condition could only have resulted as a function of organization of the inputs to the two eyes, suggesting that postretinal processes are operative in stabilized image phenomena.
