ABSTRACT: Roles of subjective occluding surfaces
and transparency by the neon effect in the formation of amodal
representation of partly occluded objects were examined
in terms of their effects on the solution
to the correspondence problem in apparent motion.
One of the following horizontally-elongated surfaces
was located between the top and the bottom motion targets
in the bistable motion display:
a textured rectangle (real surface),
an opaque illusory surface, or a transparent
illusory surface induced by the neon brightness effect.
The binocular disparity of the surface was varied.
Proportion of transversal motion perception increased
when a real or an opaque illusory surface carried a crossed disparity,
but not when a transparent illusory surface was used.
The results suggest that the formation of amodal representation
occurs in the real or the illusory surface cases
but not in the transparent surface case,
resulting in the difference in affinity
between the top and the bottom motion targets in the bistable motion display.
Effects of nonlocal information about surfaces
on the formation of amodal representation
and nonhierachical organization of surface
representation have been demonstrated.
