Napping(小睡) after learning something new could help improve your memory--- as long as you dream, scientists say. They found people who dream about a new task do it better on waking than those who do not sleep or do not dream. Volunteers were asked to learn the layout(布局，设计) of a 3D computer maze(迷宫) so they could find their way several hours later. Those allowed to take a pap and who also remembered dreaming of the task, found their way to a landmark quicker. The researchers think the dreams are a sign that unconscious(无意识的) parts of the brain are working hard to process information about the task.. Dr. Robert Stickgold of Harvard Medical School, said dreams may be a marker that the brain is working on the same problem at many levels. Study tips Co-author Dr. Erin Wamsley said the study suggests our non-conscious brain works on the things that it deem(认为) are the most important. “Every day we are gathering lots of information and new experiences,” she said. “It would seem that our dreams are asking the question, “How do I use this information to inform(影响) my life?” The scientists say there may be ways to use this phenomenon(现象) for improving learning and memory. For example, students might be better studying hard before bedtime, or taking a nap after a period of afternoon study. 小题1: Scientists say ______ could help improve your memory.
