Neural model of transfer-of-binding in visual relative motion perception

Human visual systems are much more sensitive to relative motion than to absolute motion. For example, the relative motion of two dots on a blank background is more easily detected than the motion of a single dot on a blank background. If both dots are also moved relative to the background, then their motion relative to each other remains more easily detected than their motion relative to the background. Each dot thus seems to provide a reference frame for the other’s motion.
