question 59

Essay

Figure 2.3 of the text is an illustration of the optic array and how it changes as the perceiver moves. In the first scene, the woman is sitting in a chair and can see part of her own lap, part of the red rug in front of the table (but not the part directly behind the table), most of the front legs of the table, and most of the lamp, except for the bottom of the base. When the woman stands up, the optic array changes; she can see part of the rug behind the table, less of the table legs, and the entire base of the lamp. What information about the scene is explicitly contained in the optic array? What information about the scene can only be inferred (or, not known directly) from the optic array?
