Document Summary

By the end of this section, you should know: Perception is a creation: our perception of motion is a creation of the nervous system, the fact that we can perceive motion in a static image tells you that it is created and not actually there. Depends on more than just sensation: depends on more than just what is presented on the retina. Involves interactions between systems: our own movement gives us clues about the movement of other objects. Perception involves top-down processes: when we think about motion, we are also looking at heuristics about how we think the world ought to work, we impose cognition on what is happening. Not just a simple calculation of how much an image is moving across the retina, it is an interaction of a lot of factors. Information about objects: our movement around the world tells us about the 3d nature of the objects around us, provides us key information about how objects work.
