Coffee helps to improve your memory and make you think quickly. But don't drink too much. Ways to enhance 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.
