On
Stereopsis with Double Images

Stereopsis
nay occur m the presence of large disparities despite the fact that
double images are visible. Many theorists have proposed that neural
fusion of the diplopic half-images produces the depth effect even
though the neural fusion is not accompanied by phenomenal fusion.
This paper offers the alter-native explanation that stimuli containing
widely disparate half-images are compound Panum-limiting case stereograms.
It is shown depth may be controlled by controlling disparity of fixation
in both simple and compound limiting case stereograms. It is concluded
that widely disparate half-images do not interact in the computation
of depth.
