Thresholds for the binocular and monocular perception of movement in depth for a circular stimulus object decreased as target luminance was increased to 0.1 ft-lam. Above 0.1 ft-lam little change in threshold was observed. Superiority of binocular over monocular conditions decreased with higher luminances.
