1. Some psychologists are interested in “top-down” processes in visual perception—that is, the effects of context on perceiving ambiguous stimuli. For example, if you are in a dimly lighted kitchen and see a shape that could be either a loaf of bread or a country mailbox, youwill be more likely to perceive the object as a loaf of bread. Where in the brain might contextual information affect perception? 2. I recently rented a car and soon discovered that one of the digital displays on the dashboard consisted of bright blue numbers against a black background. I found it difficult to clearly distinguish the numbers even though the blue color was really quite bright. The other digital displays were yellow, and I had no trouble recognizing the numbers they presented. Based on what you have learned in this chapter, can you offer a possible explanation for this phenomenon? (Hint: See the last paragraph in “Two Streams of Visual Analysis.”)
