Dichoptic color saturation mixture: Binocular luminance contrast promotes perceptual averaging.

abstract：:Do moving observers code attended locations relative to the external world or relative to themselves? To address this question we asked participants to conduct visual search on a tabletop. The search target was more likely to occur in some locations than others. Participants walked to different sides of the table from...
