Between-object and within-object saccade programming in a visual search task.

abstract：:Binocular disparity is an aspect of natural viewing. This research investigates whether disparity affects surface color perception. Achromatic settings were obtained and compared for two stereograms of a scene with specular reflections, one stereogram with binocular disparity and one without it (cyclopean view). Binoc...

Several lines of evidence suggest that this may be due to larger base separations being processed by mechanisms that cover larger areas and which have a greater associated positional uncertainty as a consequence...
