1 Explorations of two separate motion-computation systems and the derivation of the functional properties of each. Demonstrated A dynamic stimulus that caused the first- and second-order motion perception systems to perceive motion in opposite directions, depending on viewing distance. Discovered Motiontexture interactions-stimuli that are accessible to only to second order motion analysis and then only after their texture has first been extracted. 2 Demonstrated Perceiving 3D structure from 2D visual inputs depends primarily on the first-order motion perception system. 3 New spatial interaction A textured area surround by a similar high-contrast texture appears to be of lower contrast when surrounded by neutral gray. This remarkable phenomenon contradicts all current theories of lightness perception. Investigation continuing.
