Perceptual Expectancies
Perception seems to proceed in two major ways. In bottom-up processing, we analyze information starting at the "bottom" with small units (features) and build upward into a complete perception (Goldstein, 1984). The reverse also seems to occur. Many experinces are organized using one's knowledge of the world. This is called top-down processing. In this case, pre-existing knowledge is used to rapidly organize features into a meaningful whole.

Another good example of top-down processing is found in perceptual expectancies. A runner in the starting blocks at a track meet is set to respond in a certain way. Likewise, past experience, motives, context, or suggestion may create a perceptual expectancy that sets you to perceive in a certain way. If a car backfires, runners at a track meet may jump the gun. As a matter of fact, we all frequently jump the gun when perceiving. In essence, an expctancy is a perceptual hypothesis we are very likely to apply to a stimulus--even if applying it is inappropriate. Perceptual sets often lead us to see what we expct to see. For example, let's say you are driving across the desert. You are very low on gas. Finally, you see a sign approaching. On it are the worlds FUEL AHEAD. You relax, knowing you will not be standed. But as you draw nearer, the words on the sign become FOOD AHEAD. Most people have had smilar expxeriences in which expectation altered their perceptions. Perceptual expectancies are frequently created by suggestion.......
