Abstract
Minimum displacement thresholds were measured using a compound motion stimulus, in which a single bar split into oppositely moving component s, having different luminances and absolute displacements, The results fit a simple model in which observers detect the movement of the cent roid of the combined luminance pattern of the two components. This was so even when the two components were separated by more than the stati c spatial resolution limit of 30 sec arc.
