Describe one of the visual illusions you learned about in this chapter, and explain how it fools the eye.

What will be an ideal response?

Student answers will vary. A sample answer follows.
In the Ponzo illusion, the cat near the top of the image looks bigger. But when I measure both cats, I realized that they are the same size. My retinas created accurate images of each cat. However, the linear perspective of the railroad tracks fooled me. Because the narrowing tracks looked further away, my brain was fooled into thinking that the cat on that narrowing section was larger than the other one.
