Document Summary

Image of environment moves across retina but environment is perceived as stationary: what mechanism explains these ^3 situations, ecological approach (first attempt to explain ^): gibson. Image display signal ids: movement of image stimulation receptors across retina: 2. Motor signal ms: signal sent to eyes to move eyes muscles: 3. Allows us to shift our attention: even when freely viewing object or scene without searching for target, we move our eyes approx. Inattentional blindness: failure to notice obvious change in visual scene: sometimes termed change blindness, simons and chabris: subjects watched and attended to a video over failed to notice bizarre event i. e. who dunnit video. Ch 5: why is it so difficult to design a perceiving machine: stimulus on receptors is ambiguous. Inverse projection problem: an image on the retina can be caused by an infinite number of objects: objects can be hidden or blurred, occlusions are common in the environment.
