What is memory? Scientists believe that memory can be divided into short-term memory, medium-term memory and long-term memory. The essence of short-term memory is the repetition of immediate physiological and biochemical reactions in the brain, while medium-long-term memory is the structural changes and the establishment of fixed connections in brain cells. For example, how to ride a bike is a long-term memory. Even if you haven't ridden it for many years, you can still ride it. Medium-term memory is an unstable change of cell structure, which will become long-term memory only after repeated consolidation. Short-term memory is the biggest and weakest memory. A person only keeps 1% memory every day. \x0d\ Understand that memory needs constant review and consolidation, and then you can master the tricks of enhancing memory from both material and technical aspects. Materially, we should eat more foods that are conducive to memory, such as celery, walnuts, sesame seeds and lean meat rich in zinc, phosphorus esters and some unsaturated fatty acids. \x0d\ skills are actually done according to the physiological laws of memory. \x0d\ First, we should concentrate on listening, thinking and absorbing in class to gain deep and short-term memory. \x0d\ Review the next day after class; In a few days, when the memory begins to fade, consolidate it and tidy it up. "Learning from time to time is a pleasure", and review it once every month or two. This can turn short-term memory into medium-and long-term memory, and achieve the best memory effect in the least time. \x0d\ Secondly, it is best to review the lessons to be recited in a quiet environment in the morning or evening. \x0d\ Experiments show that the best time for memory function is 6- 10 in the evening and 6-8 in the morning. At the same time, pay attention and don't be disturbed or interrupted by other things. Never recite while listening to the walkman. This is because only one center is allowed to be excited when the brain works. If there are several excitement points at the same time, you will be absent-minded or half-hearted, and the memory effect will be greatly reduced. \x0d\ Third, be comfortable and don't be nervous when remembering things. \x0d\ When nervous, the secretion of norepinephrine increases, which is the enemy of impairing attention and memory. On the contrary, in a relaxed environment, vasopressin is secreted by the posterior pituitary gland, which is of great benefit to enhancing memory function. \x0d\ Fourthly, we can make up some jingles to sort out and summarize knowledge, so that knowledge can form a memory system and network, and the memory effect can be enhanced through association. \x0d\ For example, when memorizing the names of the "Eight Masters of Tang and Song Dynasties", you can remember the eight surnames of "Han, Liu, Ou (Yang), Wang and Zeng" first, and then infer all the names conveniently. Fifth, try to understand what you want to remember. The so-called understanding, physiologically speaking, is to put your knowledge into the memory network and establish a deep fixed connection. Memorizing things you don't understand is a waste of memory and you can't remember them well. \x0d\x0d\ Ten ways to enhance memory \ x0d \ Memory is the reflection of past experience in the human brain. It includes four basic processes: memory, retention, reproduction and recall. Its forms include image memory, concept memory, logical memory, emotional memory, sports memory and so on. The enemy of memory is forgetting. The essence of improving memory is to avoid and overcome forgetting as much as possible. As long as you exercise consciously and master the laws and methods of memory in learning activities, you can improve and improve your memory. \x0d\ Here are 10 ways to enhance memory: \ x0d \ 1. Note that as long as you concentrate on memory and eliminate distractions and external interference, the cerebral cortex will leave a deep and unforgettable memory trace. If you are distracted and concentrate on doing two things, the memory efficiency will be greatly reduced. \ x0d \ 2。 If you are interested in learning materials and knowledge objects, it will be hard to remember even if you spend more time. \ x0d \ 3。 Understanding memory Understanding is the basis of memory. Only what is understood can be remembered for a long time. It's not easy to learn by rote. For important learning content, if we can combine understanding with reciting, the memory effect will be better. \ x0d \ 4。 Excessive learning means memorizing the learning materials several times on the basis of memorizing them, to the extent that you can memorize them. \x0d\5。 The speed of reviewing and forgetting in time is fast first and then slow. While the iron is hot, reviewing and consolidating what you have just learned is an effective means to strengthen memory traces and prevent forgetting. \ x0d \ 6。 When you often recall your study, try to keep recalling, so that mistakes and omissions in your memory can be corrected and the difficulties in your study can be remembered more firmly. When you are free, you can often recall the objects you have remembered in the past, and you can also avoid forgetting them. \ x0d \ 7。 Audio-visual combination can use the functions of language and visual and auditory organs at the same time to strengthen memory and improve memory efficiency. Much better than a single silent reading. \ x0d \ 8。 Various means, flexible use of classified memory, chart memory, shortening memory, compiling outline, taking notes, cards and other memory methods can enhance memory. \ x0d \ 9。 Generally speaking, the best memory time is 9~ 1 1, 3~4 pm and 7~ 10 pm. Use the above-mentioned hard-to-remember learning materials, and the effect is better. \ x0d \ 10。 Scientific use of the brain can greatly improve the working efficiency of the brain, prevent excessive fatigue and maintain a positive and optimistic mood on the basis of ensuring nutrition, active rest and physical exercise. This is the key to improving memory. \x0d\ Fifteen points to improve memory \x0d\ How can we improve memory? \x0d\ 1。 Calm down-first, let the brain calm down. \x0d\ Second, fatigue will reduce the working efficiency of the brain. \x0d\ Third, you must have confidence and remember \x0d\ Fourth, you must find a memory method that suits your own characteristics. \ x0d \ v. Interested in objects in memory \x0d\ VI. Strong motivation can promote memory. \x0d\ VII。 When you are associated with pleasant things, it is easy to remember. \x0d\ VIII。 Stimulation can make brain cells young and sharp. \x0d\ IX。 Careful observation helps to remember. \ x0d \ x. Fully understand the memorized object \x0d\ XI. Capture the object of memory with images. \x0d\ xii。 It is good for memory to compose irrelevant memory objects into songs. \x0d\ XIII。 Characteristic memory method. \x0d\ XIV。 Decentralized memory is sometimes better than centralized memory. \x0d\ XV。 Mobilize the cooperative memory of various organs of the body. \x0d\ Is there any way to improve memory \x0d\ Q: Hello, doctor! I am a junior high school sophomore. The study pressure is great, but I feel that my memory is not good. I envy some classmates. They remember quickly, but it takes me several times to remember. Sometimes I am depressed. Is there any way to improve memory? \x0d\ A: Hello! First of all, I want to say that there are differences between people, even great differences in some aspects. Give up the comparison and accept yourself, and your distress will be alleviated. As for the method of memory, we can discuss it together. \x0d\ If you want to improve your memory, you must first know some common sense about memory. Simply put, memory is divided into three stages. The first stage is called the encoding stage. This is like the information input of a computer. To encode, only the encoded information will be saved. This stage has a lot to do with attention. We can't recall a lot of information, and some problems appear in the coding stage. We turn a blind eye to many things and don't observe them carefully. We think we remember, but that's not the case. For example, although we use money every day, we can't immediately describe the pattern on the back of a dollar bill. This is because although we saw it, we didn't take the initiative to pay attention to it, so we didn't code the relevant information, and naturally we couldn't recall it. The second stage is called short-term memory stage. At this stage, the memory retention time is very short, usually from a few seconds to more than ten seconds. For example, if you call 1 14 and find the phone number you want, write it down in your mind. When you want to dial it, you can't remember it at once. The method of testing short-term memory is simple. You can ask a person to say four unrelated numbers or English letters. You can repeat them immediately and then increase them gradually to see how many you can remember at most. The average person is always 7 2. Therefore, we know the capacity of short-term memory is limited. Short-term memory is the basis of long-term memory, which will be forgotten soon without repeated practice. If you continue to practice before it disappears, it can be transformed into long-term memory, which is the third stage of memory. Long-term memory is also called permanent memory, which means that it has been kept for a long time. \x0d\ Through the above understanding, we know that if you feel that your memory is not the best, it is not necessarily that your brain is more stupid than others, but that you have not handled the three stages of memory mentioned above well. If you improve your memory in these three stages, you may improve your memory. Let's focus on how to improve memory. \x0d\ We start with the improvement coding stage. First of all, coding always starts with attention, so you should pay full attention to what you want to remember. Remember, if there is no coding or coding error, you can't remember it, even if you have a smart brain. You should concentrate on eliminating or reducing external interference as much as possible. For example, you can choose a quiet place to study and don't be distracted by other things, such as snacks, novels and magazines. Some students pay attention to emotional appeal while reading, which is also a bad habit. Secondly, carefully observe the details you want to remember. For example, if you want to remember a person's appearance, you should carefully observe his eyes, nose, forehead, chin and ears. Third, say to yourself what you want to remember, such as "He is tall, with small eyes and dark skin? Quot This is equivalent to double coding of impression and voice, which is more reliable. \x0d\ Let's talk about how to improve short-term memory. As we mentioned earlier, the capacity of short-term memory is limited, so in order to improve short-term memory, we must reduce the burden of memory. We can use abbreviations, such as "WHO", which we know is the abbreviation of "World Health Organization". We just need to remember these three letters and take them as clues to remember everything. In addition, we can also make irrelevant objects meaningful through homophonic methods, which can also reduce the burden of memory. For example, pi is "3. 14 159". As we said before, because of the limited capacity of short-term memory, most people can only remember about seven irrelevant numbers at a time. But if we read it as "a temple on the top of the mountain, a pot of wine", it will become meaningful, indirectly expanding the memory capacity and reducing the memory burden. Because the short-term memory time is very short, in the final analysis, it depends on repeated practice if you want to preserve it for a long time.
