Do more with less memory

Chapter 11 Multiple Senses "Attack" Simultaneously to Memory
Someone has done such an experiment, using two methods to let the three groups of students memorize the contents of ten pictures. The students in the first group were only told the contents of the pictures, and they were not allowed to look at the pictures; the students in the second group were only asked to Look at the pictures, but don't tell them the content of the pictures; the third group of students not only show them the pictures, but also explain them to them.

After a period of time, the memory of these ten pictures was checked by the three groups of students. As a result, the first group remembered the least, only 60%; the second group slightly more, 70%; the third group remembered the most, reaching 86%.Experiments have shown that the more sensory organs mobilized during learning, the better the effect of memory.

People have this kind of experience: skating, dancing, painting and other content related to movements that they have learned before are the most difficult to forget; poetry, songs and other chanting content are second; books that have only been read with eyes, Content such as pictorials are the easiest to forget.When learning a foreign language, it is easier to forget the words that are not read or written, but it is not easy to forget the words that are read, written, and used.The reason for this is that they belong to different memories.

The memorization that only uses the eyes is the memory of the brain for visual symbols, which is called "visual symbol memory". memory". "Visual symbol memory" forgets faster, while "motor memory" forgets slower, even for a lifetime.

The movement actions memorized by the cerebellum are not limited to the movements of the trunk and limbs, but also include the subtle movements of the muscles in various parts of the body.For example, a series of accurate, persistent, and rapid movements of a violinist can be reproduced without thinking, almost becoming a habitual movement, and the skillful and accurate movements of calligraphers, painters, and sculptors are all related to motor memory.

The multi-channel synergistic memory method is a method of mobilizing various sensory organs and motor organs in the process of memory, cooperating and participating in memory together.There are many channels for people to know things, and the cooperation of each channel is conducive to grasping and remembering things, and it is easier to establish various connections in the brain that are easy to recall.This method is widely used in learning practice, mainly in the combination of listening, speaking, reading, writing, thinking and practical operation.Suitable for memorizing various materials.

Studies have shown that according to experiments and research by foreign scientists, there are great differences in the rate of knowledge absorption by various senses.A healthy person's vision, hearing, smell, touch, taste and other five sensory organs absorb knowledge as follows: vision accounts for 83%, hearing accounts for 11%, smell accounts for 3.5070, touch accounts for 1.5%, and taste accounts for 1%.From the perspective of memory efficiency, 3% of the knowledge acquired by hearing alone can be remembered in 60 hours, and only 3% can be remembered after 15 days; 3% of the knowledge acquired only by vision can be remembered after 70 hours, and 3% can be remembered after 40 days %; visual, auditory and use of the acquired knowledge, 3% can be remembered after 90 hours, and 3% can still be remembered after 75 days.

This shows that on the whole, the utility of multiple sensory memory is good.

This is because multiple senses receive knowledge at the same time, so that many pathways can be established on the cerebral cortex of the same content, leaving multiple traces. Even if a certain trace is weak, there are other traces that can reproduce the memory.In addition, because multiple senses perceive knowledge and memory materials in a multi-dimensional and multi-level manner, and reflect an object three-dimensionally, the information will be transmitted to the brain through different sensory nerve pathways, playing the role of retelling and strengthening from different angles, thus making the impression deepen.

Modern scientific research has found that the human left brain focuses on abstract thinking and is in charge of language, algebra, logic, etc.; the human right brain focuses on image thinking and is in charge of intuitive images, music, geometry, and comprehensive creation.Research by psychologist Richard Thompson and medical scientist Skell has proved that a part of the human cerebellum called the "inferior olive nucleus" plays an important role in memory.In learning, fully mobilizing the enthusiasm of various parts of the human brain, such as the visual center, auditory center, language center, and motor center, to coordinate memory, has a significant effect on improving memory quality.

It should be particularly emphasized that through practical operations such as experimentation and production, not only can perceptual knowledge be enhanced and memory effect improved, but also the number of brain grooves can be increased and deepened due to frequent finger movements, which can improve intelligence and prevent or delay brain aging.In the motor center of the brain, the area of ​​cerebral cortex corresponding to a thumb is equivalent to 10 times the area of ​​cerebral cortex corresponding to a thigh.The number of brain cells that control the entire torso in the brain is only 1/4 of the number of brain cells that control the hands.Participating in experiments and productions with the left hand, in particular, is conducive to developing the right brain and cultivating creativity.

This is because reading aloud can concentrate energy, and at the same time, since the two activities of making a sound and listening to one's own voice are carried out at the same time, the two organs work together, so the stimulating effect on the brain can be enhanced.

H. Shuliman, famous for excavating the ruins of Troy, is known for his linguistic genius.He started from learning Greek and became proficient in several languages. His learning method was to read aloud, and he often read late into the night.He is said to have been kicked out of his apartment several times because of this.He can be fully proficient in a foreign language in only 3 to 6 months.

When we use a dictionary to look up English words, if we turn the book while reading, we can quickly find them; if we don’t make a sound, similar words are nearby, and it is easy to make mistakes.When we look through the pages one by one, suddenly an eye-catching word jumps into our eyes, we will look at this word first, and as a result, we forget the word we originally wanted to look up.If you keep chanting the word you want to look up, you can just look it up.You can judge whether the word you checked is correct at any time by reading it aloud.

Marx "often wrote down in his manuscripts all kinds of practical information that he wanted to enrich his memory", "he would reread his notes and marked places in the book at regular intervals to consolidate his very strong accurate and precise memory".In the process of writing "Das Kapital", Marx read, took notes, and extracted more than 1500 books, and wrote more than 100 notebooks (including manuscripts, excerpts, outlines, and notes).He carefully studied all subjects related to political economy.It took him 40 years of tireless work to complete this brilliant work.

This is the multi-channel collaborative memory method, one of the most widely used and effective memory methods.Remember the key "five to" - see with your eyes, think with your heart, write with your hands, read with your mouth, and hear with your ears.
