How to Improve Your Memory

Man still has a lot to learn about the most powerful and complex (复杂的) part of his body—the brain.It may be surprising to learn that it isn’t age that makes you lose your memory. The reason could be that you have a “lazy” memory, not an old one. Like your body, your memory improves with exercise. Once given plenty of exercise, the brain keeps its power. Before discussing how to improve the memory, let’s look at how the brain works. There are two sides to the brain, the left and the right. The right side deals with senses (what we see, hear, feel and smell). It’s the creative and imaginative side. The left side is related to logical (逻辑的) thinking, which analyzes (分析) information and puts it in order.Some recent research suggests that we remember everything that happens to us. The problem most of us have is recalling (回忆) events. Most forgetting takes place immediately after learning. An hour after learning something new, more than 50% has been forgotten. After a month, 80% has been forgotten, and so on.

This research is very important. It shows if you review new material you have learnt, you remember much more. So it’s of the greatest importance to review newly learned material often, and have breaks often. You best remember what you learn at the beginning of a learning period and at the point where we stop. After the break, review what was learned before the break and then continue learning the new material. These breaks should happen every 20 or 45 minutes.

Other experiments have shown the brain needs time to take in what has been learned. The time necessary for this is 5 to 10 minutes. After the break, the memory will have taken in what it has just learned, and more will be remembered. During this period it is important to exercise the right side of the brain, because the left side is used during the learning period. Therefore you should relax. Listening to music, breathing in fresh air, and looking at a picture are all ways of using the other side of the brain. So when you are studying alone, make a plan which shows when to have breaks and to review newly learned material immediately before you begin studying again. If you do in this way, your memory will improve.
