Binocular depth mixture with non-symmetric disparities

If two thin binocular vertical lines which have the same binocular direction but different disparities with respect to a fixation point are flashed simultaneously, they interact in the determination of perceived depth (binocular depth mixture). Perceived depth depends on both disparities and their relative luminances. Previously this phenomenon has been studied in a situation where the disparities were symmetric with respect to the fixation point. Here the non-symmetric case is described. The results are similar to those in the symmetric case and are consistent with the hypothesis that stereo depth channels are broadly tuned to disparity.
