Our understanding of the surface representation stage has just begun and many questions are yet to be answered. The solutions to these questions will bring us closer to discerning the mystery of visual perception and the workings of the brain. Surfaces vs. features in visual search. Apparent motion determined by surface layout not by disparity or by 3-dimensional distance. Illusory contour formation affected by luminance contrast polarity.
Terrain influences the accurate judgement of distance.
