How to enhance memory? Memory is the reflection of past experiences in the human brain. It includes three 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. Improving memory is actually trying to avoid and overcome forgetting. As long as you exercise consciously and master the laws and methods of memory in learning activities, you can improve and improve your memory. Here are ten ways to enhance your memory. 1. Attention. As long as you concentrate on your 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. 2. Strong interest. If you are not interested in learning materials and knowledge objects, it will be difficult to remember even if you spend more time. 3. Understand memory. Understanding is the basis of memory. Only what is understood can be firmly and permanently remembered. 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. 4. Overstudy. That is to say, on the basis of remembering the learning materials, remember them several times more to achieve the degree of memorizing and remembering. The best degree of over-learning is 150%. 5. Review in time. The speed of forgetting 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. 6. Always remember. When studying, constantly trying to recall can correct memory mistakes, make up for omissions, and make the hard-to-remember learning content stronger. When you are free, you can often recall the objects you have remembered in the past, and you can also avoid forgetting them. 7. Combine reading, thinking, watching and listening. We can use the functions of language and visual and auditory organs at the same time to strengthen memory and improve memory efficiency, which is much better than single silent reading. 8. Use a variety of memory methods. According to the situation, flexible use of memory methods such as classified memory, characteristic memory, homophonic memory, argument memory, associative memory, interesting memory, chart memory, shortening memory and compiling outline, taking notes and cards can all enhance memory. 9. Master the best memory time. Generally speaking, 9 ~ 1 1 in the morning, 3 ~ 4 in the afternoon and 7 ~ 10 in the evening are the best memory time. Use the above-mentioned hard-to-remember learning materials, and the effect is better. 10. Use your brain scientifically. On the basis of nourishing and maintaining the brain, active rest and physical exercise, using the brain scientifically, preventing excessive fatigue and maintaining a positive and optimistic mood can greatly improve the working efficiency of the brain. This is the key to improving memory. Method and training of concentration: mary pierce, a two-time Grand Slam winner, once said after winning the Italian Open in 1997: "I spent a long time training my concentration, and now I have begun to feel the improvement in this respect. I think the key is not to think about the past and the future, and not to think that you will lose or win. Before that, I always couldn't help thinking about these things. Now I just want to do my best. When I can do this, I can play well. " Stay focused According to Pierce, the ability to focus on the present, that is, the ability to focus on the game, is the ability to "not think about the past and the future." Fundamentally speaking, focus is to maintain three unifications: 1, and I just want to be myself in the unity of individuals. 2, the unification of the location, I am here. 3. The unification of my present time. I often hear players complain like this: "I always pay attention to the people around me." Or "I don't know where I am today." Throughout the second set, I couldn't concentrate at all because I kept thinking about the easy volley I missed in the first set. In the above three examples, it is obvious that the unity of the individual (himself), the unity of the place (here) and the unity of the time (now) have not been observed, which is also the reason why the player can't concentrate. This is what we call inability to concentrate. The following is a summary of the concentration mechanism: personal unity-the unity of other people's concentration places here-the unity of time in other places in the past-now-in the future, we can further summarize it as follows: if you can't concentrate in a game now, you must have problems in one or more of these three aspects. First of all, it is important to know what is wrong. Here's how to tell: 1, whether people around you distract you: spectators, opponents, referees, players on the next court, parents, friends, or coaches. 2. Your idea has gone to other places: the venue next door, your home, office, school, club and so on. 3. Are you thinking about the past (the point you just lost) or thinking about the future (the next tour, if you lose, you will have no chance. Finding the reason for your inattention is the key to refocusing. The next thing to pay attention to is: how does the intangible thing of attention play a role in the competition? And what role does attention play in a player's game? To put it bluntly, focus on a player's technical, tactical, physical and psychological energy. We can use the example of laser to make a simple explanation: take a beam of scattered light, we concentrate it on a point, then compress it to the limit, and we get a laser. This kind of laser is enough to cut steel. Complete concentration is as powerful as a laser. Complete concentration can perfectly multiply your conscious energy, but also stimulate your unconscious energy, including your creativity and intuition. When you hear a player say, "I'm in good shape." Or "I have all the balls today and feel great." In other words, he or she is going through a period of high concentration. Those real champions have gone through this stage many times more than other players. This is why they always surpass themselves and give full play to themselves. So what makes them reach this state of complete concentration? Are they born with this ability? Of course, everyone is different after birth, and their concentration is different. But Pierce has told you that you can take the time to train and improve it. So the only thing you need to do is practice. Practice What you need to practice is to focus your attention on a specific and unique object. The point is: there is only one object. The following are the objects that you can concentrate on in the competition: In the duet:-The bouncing sound and hitting sound of the ball on the court-Between the points where you breathe:-A word or sentence repeated to yourself-Your breath, your brain must be completely filled with the objects that you concentrate on, and no other conscious things can enter. Training methods Five ways to train off-court attention: 1, take a tennis ball, put it in front of you, stare at it, and concentrate on it completely. Keep this tennis ball in mind and try to increase the training time gradually. (external vision) 2. Close your eyes, use your imagination to imagine the ball, concentrate, and try to gradually increase the training time. (internal vision) 3. Take a metronome, turn it on, focus your attention on the rhythm, let the rhythm fill your mind, and if something else appears in your mind, let it float like a cloud. (external ear) 4. Choose a sentence or a word, preferably positive, and then repeat it to yourself. Play it over and over in your head like a recording. Try to gradually increase the training time. (Internal hearing) 5. Watch your breath. Feel the air coming in and out of your lungs and let your breath calm you down. Every time you inhale, it seems that your ability to concentrate has increased. Every time you exhale, it seems that other distractions are called out. Inhale through the nose and exhale through the mouth. Five ways to pay attention on the training ground (external auditory and internal kinesthetic): 1, focusing on the ball in flight. Fill your mind with the ball of this sport and don't let anything else in. Keep your attention on the ball. (external vision) 2. Focus on the bouncing sound of the ball or the hitting sound between you and your opponent, and keep up with the rhythm. (external ear) 3. The opponent inhales when hitting the ball and exhales when hitting the ball. Focus on your breath and let it calm you down. (Internal kinesthetic and external auditory) 4. Before hitting the ball, say "attack", "face up" or similar words to yourself in your mind, so that these words can fill your mind. (Internal hearing) 5. Between points, let a static or moving imaginary image appear in your mind, such as a special tactical arrangement or your own image full of fighting spirit. You can also imagine words like "calm down" and "come on" appearing in your mind. These words must be shorter, which makes it easier to concentrate completely. 12 food types that can enhance memory There are countless billions of nerve cells in the human brain that are constantly carrying out heavy activities. Scientific research has confirmed that diet is not only a necessity to maintain life, but also plays a very important role in the normal operation of the brain. Some foods help to develop people's intelligence, make people's thinking more agile, concentrate more, and even stimulate people's creativity and imagination. Nutrition and health care experts have found that some foods that help to strengthen the brain and improve intelligence are not expensive and hard to find, but cheap and ordinary things, which can be seen everywhere in daily life. The following foods are very beneficial to the brain, so mental workers and school students may wish to choose foods frequently. 1, milk. Milk is a nearly perfect nutrient. It is rich in protein, calcium and essential amino acids for the brain. Calcium in milk is most easily absorbed by people and is an indispensable and important substance for brain metabolism. In addition, it also contains vitamin B 1 and other elements that are very beneficial to nerve cells. If you have excessive insomnia with your brain, a cup of hot milk before going to bed will help you fall asleep. 2. eggs. Brain activity function and memory intensity are closely related to acetylcholine content in the brain. Experiments have proved that the beauty of eating chicken is that when lecithin in egg yolk is decomposed by enzymes, it can produce rich acetylcholine, which can reach brain tissue quickly after entering the blood and enhance memory. Foreign studies have confirmed that eating 1 or 2 eggs a day can supply enough choline to the body, which is of great benefit to protecting the brain and improving memory. 3. fish. They can provide high-quality protein and calcium for the brain. The fatty acids contained in freshwater fish are mostly unsaturated fatty acids, which will not cause arteriosclerosis and do no harm to cerebral arteries and vessels. On the contrary, they can also protect the cerebral vessels and promote the activity of brain cells. 4, monosodium glutamate. The main component of monosodium glutamate is sodium glutamate, which can be converted into glutamic acid under the action of gastric acid. Glutamate is the only amino acid involved in human brain metabolism, which can promote intellectual development and maintain and improve brain function. Regular intake of monosodium glutamate is helpful to improve mental retardation and memory impairment. Because monosodium glutamate can increase acetylcholine in the brain, it also has a certain effect on neurasthenia. 5. peanuts. Peanut is rich in lecithin and cephalin, which is an important substance needed by nervous system. It can delay the decline of brain function, inhibit platelet aggregation and prevent cerebral thrombosis. Experiments show that eating peanuts regularly can improve blood circulation, enhance memory and delay aging, which is a veritable "longevity fruit". 6. Xiaomi. Vitamin B 1 and B2 in millet are 1.5 times and 1 times higher than those in rice, respectively, and protein contains more tryptophan and methionine. Clinical observation shows that eating millet can prevent aging. If you usually eat more millet porridge and rice, it will be beneficial to the health care of your brain. 7. corn. Corn germ is rich in unsaturated fatty acids such as linoleic acid, which can protect cerebrovascular and reduce blood lipid. Especially, the high water content of glutamic acid in corn helps to promote the metabolism of brain cells. Eating some corn often, especially fresh corn, has a brain-strengthening effect. 8. Day lily. People often say that day lily is a "girl without sorrow" and can "soothe the nerves and relieve depression". Note: Daylily should not be eaten raw or fried alone to avoid poisoning. It is best to eat it dry and cooked. 9. Chili. The content of vitamin C in pepper ranks first among all vegetables, and it is also rich in carotene and vitamins. Capsaicin contained in pepper can stimulate taste, increase appetite and promote blood circulation in the brain. In recent years, it has been found that the "spicy" taste of pepper is also a hormone in the human body that stimulates the pursuit of career success, making people energetic and active in thinking. Red peppers are better eaten raw. 10, spinach. Spinach is cheap and humble, but it is a brain-nourishing vegetable. Because spinach is rich in vitamins A, C, B 1 and B2, it is one of the "best suppliers" of brain cell metabolism. In addition, it also contains a lot of chlorophyll, and it also has the function of strengthening the brain and improving intelligence. 1 1, orange. Oranges contain a lot of vitamins A, B 1 and C, which are typical alkaline foods and can eliminate the harm of a lot of acidic foods to the nervous system. Eating oranges in moderation during the exam can make people energetic. In addition, lemon, citrus, grapefruit and so on. It has a similar effect and can replace oranges. 12, pineapple. Pineapple contains a lot of vitamin C and trace element manganese, and it is low in calories. Often eat shengjin refreshing effect. Some people call it a fruit that can improve people's memory. Pineapple is often the favorite fruit of some musicians, singers and actors, because they have to memorize a lot of music scores, lyrics and lines.
