These last two chapters provided an overview of some of the neural machinery of visual perception, including the multiple visual areas scattered throughout the brain. We are now ready to shift the focus to perception itself. In the next several chapters, we examine different aspects, or qualities, of vision. These qualities of vision—shape, color, movement and depth—serve to differentiate objects from one another. In discussing each of these qualities of vision, we will treat them as the final product of the visual system's processing. We will also consider what sort of mechanism would be needed to yield this product. However, the major emphasis will be on what you see, rather than on how you see.
