Document Summary
View after image in dark, push on eyeball, follow moving object with eyes, paralyze eye muscles (all lead to perception of object movement) Global optic flow moves outward or inward: focus of expansion (foe) point that stays stationary while everything else flows outward or inward, very good at it identifying where the foe is. Law of common fate if objects move together we perceive them as belonging together. Biological motion ability to recognize movements of the human body: can gather a lot of information from this without seeing an image of a human at all, eliminate all other information other than the movement. Kinetic depth effect use movement to perceive depth in an otherwise 2d image. Ramachandran people were shown ambiguous images, when given motion cues they were able to identify the images easier: motion improves object perception. Shiffar & freyd knowledge about human body influences motion perception: defied shortest path law because of knowledge of the human head.
