Effects of surface width on quantitative depth perception in surface edges from temporal interocular unmatched features

Previous research (Ni, Chen and Andersen, 2010) has found that there are spatial limitations in propagating quantitative depth perception of an occluding surface, from its two vertical edges to the center region. In the present study we examine whether variations in the horizontal extent of subjecti...

Summary:Previous research (Ni, Chen and Andersen, 2010) has found that there are spatial limitations in propagating quantitative depth perception of an occluding surface, from its two vertical edges to the center region. In the present study we examine whether variations in the horizontal extent of subjective surface will also alter perceived depth in vertical surface edges. In two psychophysical experiments, observers were shown temporal interocular unmatched (IOUM) features based on a vertical moving line that was partially occluded by a subjective surface. Metrical depth was perceived and we found that depth perception in the vertical surface edges can be affected by its width when the horizontal surface edges are revealed by two ends of the occluded moving line.
