Motion is everything: j. j. gibson criticized standard perception research & proposed the ecological approach instead, gibson: motion is tied up with all other aspects of vision. Studying reductionistic static stimuli is the wrong way to go: example: we don"t stand still while looking at objects but perception researchers still use static images of objects in their research. Movement: real movement, apparent movement, induced movement (a. k. a. relative movement, movement aftereffect, movement illusions in static stimuli. Motion is always there (even when it isn"t) Perception through objects assists in organization of stimuli: motion aids in perceiving objects, movement of objects or the observer"s movement, example: motion parallax and occlusion-in-motion give cues to depth of different parts of an object, revealing its structure.
