Exploring the effect of stimulus characteristics on location-based inhibition of return using abrupt and ramped stimulus presentation.

abstract：:In the natural world, a binocular discrepancy of luminance can signal a glossy surface. Using a spatial forced choice task, we have measured the ability of subjects to detect binocular luminance disparities. We show that the detection of binocular luminance disparity shares several basic psychophysical features with t...
