For the most part, we have been concerned in this chapter with veridical perception, how innate processes of organization and form description (with the help of past experience, under some conditions) enable us to reconstruct a perceptual world that adequately corresponds to the objects in the real world. Only occasionally did we encounter examples of nonveridical perception, as in the case of camouflage—–and, interestingly enough, camouflage reflects the working of the same perceptual processes of organization that ordinarily lead to veridicality. In the next chapter, the emphasis is reversed, with the focus on illusions in patterns of one kind or another. The question will be whether or not we can explain these illusions in terms of the very same principles that, under other circumstances, lead to correct perception.
