Form and motion have independent access to consciousness

Abstract

In our conscious perception of the world, form and movement are usually inextricably linked: component contours that bound and fill a moving object seem to share a single trajectory of motion. However, the apparent unity of consciousness for shape and movement is illusory. In some instances, literally invisible contours contribute to the perceived direction of motion, implying that shape and movement have independent access to our awareness of the visual scene.
