Ask three people to look out the same window at a busy street corner and tell you what they see. Chances are you will receive three different answers. Each person sees the same scene（场景）, but each perceives（察觉）something different about it.

　　 Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket（罚单）. Another may say that he sees a rush-hour traffic jam at the intersection. The third may tell you that he sees a woman trying to cross the street with four children in tow（拉着）. For perception（感知） is the mind’s interpretation of what the senses—in this case our eyes—tell us.

　　 Many psychologists（心理学家） today are working to try to determine just how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene.

Today is Tom’s birthday. After school he walks past the shop on the street corner. He looks at the window. That pair of trainers is still there. He really wants to have them very much.

　He was very sad and walks away. He knows his mother can give him anything he likes if she can. But he also knows she has no money and the trainers are too expensive. He doesn’t go home at once because his mother could notice (注意) his worry. So he goes to the park and sits on the grass. Then he sees a boy in a wheel chair (轮椅) . He finds that the boy moves the wheel with his hands. Tom looks at him carefully and is surprised to see that the boy has no feet. He looks at his own feet. “It’s much better to be without shoes than without feet.” he thinks. There is no reason (理由) for him to feel so sorry and sad. He smiles and thinks he is happier.
