1.6 SEEING A ROOM
1.6 SEEING A ROOM
”Visual experience seems continuous. One reason is that we move continuously. A deeper explanation is that our “expectations” usually interact smoothly with our perceptions. Suppose you were to leave a room, close the door, turn to reopen it, and find an entirely different room. You would be shocked. The sense of change would be hardly less striking if the world suddenly changed before your eyes.’

When we move about a room, the shapes of things change. How can these changes be anticipated, or compensated, without complete reprocessing? The results of eye and head rotation are simple: things move in the visual field but keep their shapes; but changing place causes large shape changes that depend both on angle and on distance relations between the object and observer. The problem is particularly important for fast-moving animals because a model of the scene must be built up from different, partially analyzed views. Perhaps the need to do this, even in a relatively primitive fashion, was a major evolutionary stimulus to develop frame-systems, and later, other symbolic mechanisms.
