Document Summary
Sensation and perception february 26th 2013: depth perception. The retina is flat like a postage stamp; we see a 3d image but are using a 2d retina. Things that are close to you will occupy a larger visual angle than things that are farther away. Is it a small object or is it just very far away: approaches to the study of depth perception. You take a lot of info or cues from the image to reason or figure out how far the object is (r. gregory"s theory) (constructive approach) Overlap (occlusion) if two things are overlapping each other, the one in the front must be closer than the one in the back. The way in which an object is shaded can determine the way it is perceived and makes it look 3d. Linear perspective (convergence perspective) ; there is a vanishing point alone the horizon on which everything comes together in the distance.
