The influence of visual motion on perceived position.

The ability of the visual system to localize objects is one of its most important functions and yet remains one of the least understood, especially when either the object or the surrounding scene is in motion. The specific process that assigns positions under these circumstances is unknown, but two major classes of mechanism have emerged: spatial mechanisms that directly influence the coded locations of objects, and temporal mechanisms that influence the speed of perception. Disentangling these mechanisms is one of the first steps towards understanding how the visual system assigns locations to objects when there are motion signals present in the scene.
