Young children across the globe enjoy playing games of hide and seek. For them, there's something highly exciting about 41 someone else's glance and making oneself unable to be seen. However, we all witness that preschool children are remarkably 42 at hiding. They often cover only their eyes with their hands, leaving the rest of their bodies 43 . For a long time, this ineffective hiding method was 44 as evidence that children are hopelessly "egocentric"（自我中心的）creatures. But our 45 research results in child developmental psychology 46 that idea. We brought young children aged 2-4 into our Minds in Development Lab at USC. Each 47 sat down with an adult who covered her own eyes or 48 . We then asked the child if she could 49 or hear the adult. Surprisingly, children replied that they couldn't. The same 50 happened when the adult covered her own mouth: 51 children said that they couldn't 52 to her. A number of 53 ruled out that the children misunderstood what they were being asked.The results were clear: Our young subjects 54 the questions and knew 55 what was asked of them. Their 56 to the questions reflected their true 57 that "I can see you only if you can see me, too." They simply 58 mutual（相互的）recognition and regard. Our 59 suggest when a child "hides" by putting a blanket over her head, it is not a result of egocentrism. In fact, children consider this method 60 when others use it. 41.
