When you are walking through a zoo and you enter the "Africa Experience" exhibit, you would be very surprised to see a polar bear or a penguin, but probably not at all surprised to see an elephant or a rhinoceros. Why is that?

a) because of crosslinking of sensory experiences
b) because the opponent-process theory allows for only one "schema" of animal to occur at a time
c) because bottom-up processing will not allow you to accept an animal out of its place
d) because of a perceptual set about what you will see in that exhibit

ANS: D, The perceptual set explains that past experiences create expectancies for future sensory/perceptual events. In this case, your knowledge of what animals "should" be in Africa would cause you to be surprised when you see animals that "should not" be there.
