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.

It is common to believe that learning just takes place in school, but much of human learning happens outside the classroom, even from birth and people continue to learn throughout their lives.

Even before they enter school, young children learn to walk, to talk, and to use their hands to use toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in their environments. They learn how to communicate with their parents, grandparents, siblings, friends, and other people important to their world. When they enter school, children learn subjects like reading, writing, and maths. They also continue to learn a lot outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for communicating with other children. After they finish school, people must learn to deal with many changes that affect their lives, such as getting married, raising children, and finding and keeping a job.

Because learning continues throughout our lives and influences almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Scientists, social workers and other human service workers need to understand how certain experiences change people’s behaviors.

Learning is closely related (相关的) to memory, which is the storage(储存) of information in the brain (大脑). Scientists who study memory are interested in how the brain stores knowledge, where this storage takes place, and how the brain later offers knowledge when we need it. However, scientists who study learning are more interested in behavior and how behavior changes as a result of a person’s experiences. ?

It is reported that 300 million people in China have eyesight trouble. More and more parents hope to save their children’s eyesight with medicine, or by correcting the ways that children read and sit. But in fact, one should start with the exercise on one’s feet. Here are three ways to save eyes:

First, don’t tie your shoes too closely. Try wearing comfortable and soft socks or walking without socks and shoes at home. While you are traveling, try wearing cloth shoes in order to improve blood circulation(循环).

Second, walking on tiptoes is good for one’s eyesight. It can fight against eyesight trouble. Numbers show that most of ballet(芭蕾) performers’ eyesight is better.

Third, rope skipping(跳绳) can also be good for one’s eyesight. While skipping rope, one has to move quickly, making both the brain and the eyes excited. It may also help make one grow taller.

Besides foot exercises, it is good to pull one’s ears. Pulling the ears 20 times quickly is also a great way. It can keep one’s eyes healthy.
