E. g. she would have trouble crossing the street because she does not see cars moving, but sees a car far away, then suddenly close. She cannot see all types of movement. Low level vision: lower to the ground floor of cognition. First thing you do is low level analysis: making decisions about edges, motion, depth . High level vision: try to recognize objects, faces, words. Daniel kish is blind; uses echolocation, or sound to see. Sees environment as images in his brain using the sound he hears. He describes the same visual perception as we have, but he is sending the signal that goes out and back. Asked to make a distinction about the look of the object. Done in fmri; difficult to do echolocation with noise of fmri.
