Rumors, left-handers are smarter! wrong! The division of labor between the left and right brains is different.

Text|Jing Ma 01 I remember when I was a child, Jing Ma's sister used her left hand to eat, but because she often fought with other people at the dinner table, her mother began to correct her to eat with her right hand. #讀 Zero Zero Plan# After she went to school, she started writing with her left hand. Originally, her mother wanted her to change to writing with her right hand. If you can write with your left hand, your child will be smarter in the future! So my mother didn't deliberately correct my sister's habit of writing with her left hand, but as she grew up, my sister found that many of her classmates were writing with her right hand, and she gradually switched to writing with her right hand. Only my sister uses her left hand, and she is also the person who reads the most! So I always thought "lefties are smart" was right. 02 Later, when I grew up in medical school, I learned that there is no such thing as "left-handed is smarter". In medicine, left-handed people are actually called "left-handed", and right-handed people are called "right-handed". In 1933, psychologists from Bucknell University in the United States asked 339 newly admitted male students to receive IQ tests, and then they accepted the strength of the left and right hands. , it has nothing to do with the ratio of the strength of the two hands. Does a person usually use the left hand or the right hand? It is related to his brain dominance. People with an advantage in the left brain generally use the right hand, and people with an advantage in the right brain are generally left-handed. The functioning of the left and right brains of the human body is asymmetric. Generally, the left brain is in charge of language, mathematics, analysis, logic and other functions, while the right brain is mainly responsible for music, art, imagination and other functions. So left-handed people are more right-brained, more divergent thinking, more aesthetic, look more like artists, more imaginative, and seem smarter. But many scientists have found that there is no relationship between left-handed and right-handed strength, strength ratio and children's IQ. 03 But some people may say, you see Obama is also left-handed, and Leonardo da Vinci, Einstein are also left-handed. In fact, Leonardo da Vinci, Einstein, these belong to the artistic category, and the imagination category will be more developed, so it is normal for them to use the left hand. Moreover, the education of children abroad is relatively relaxed. Parents will not deliberately correct whether the child uses the left hand or the right hand after birth. However, in China, many parents find that their children are accustomed to using the left hand and will correct them, so they should correct their children to use the right hand. Therefore, there are relatively few left-handed people in China! We say "ingenuity", it is true that children's ingenuity can exercise their brains. Rather than saying that children are smarter with their left hand, it is better for parents to let their children exercise their hands more to make them smarter.

From the birth of the child, parents should encourage these habits of hands to make the child smarter

The first: Children under the age of one can eat their hands without correction. Many children will start to drool at three or four months, and will slowly put their fingers into their mouths. This is actually the child building his own neural channels. He uses his mouth and hands to feel whether the hands are soft or hard, long or short. Children's mouth is more sensitive, and using the mouth and hands to understand the world will allow children to understand the world faster and better. In fact, this is a kind of stimulation to the brain. The feeling of the mouth and the feeling of the hand are integrated together, so that the child will understand what the shape of the hand is! So if the child eats fingers before the age of one, don't worry about him. If the child still eats when he is two years old, then pay attention. The second one: Children are not afraid of getting dirty when they eat by themselves. Some children like to eat by themselves at about 10 months. Many parents feel that children eat all over their face, clothes, and floors, and they clean up by themselves. Too much trouble. Worrying about children not getting enough to eat, and worrying about children wasting food. In fact, eating by yourself is the best way to exercise. It can not only exercise children's independence, but also exercise children's fine motor skills. While training children's fine motor skills, it has a very strong stimulating effect on the children's brain. . Therefore, it is recommended that parents let the child eat by himself when he wants to eat by himself, so that it can be more conducive to stimulating his brain. No. 3: When the child likes to pinch and pinch things, give him the corresponding toys. The child will have a sensitive period of small movements, especially like to pinch holes in the wall, or like to pinch some small things. This is actually exercising the child's fine motor skills and stimulating the development of the child's brain. At this time, some parents will worry that the child will pick up the finger, or pick the small hole in the wall, and damage the wall in the home. Picking for children, but in fact, this is not conducive to children's brain development. It is suggested that parents can buy a set of picture books for their children. #pgc-card .pgc-card-href { text-decoration: none; outline: none; display: block; width: 100%; height: 100%; } #pgc-card .pgc-card-href:hover { text-decoration: none; } /*pc style*/ .pgc-card { box-sizing: border-box; height: 164px; border : 1px solid #e8e8e8; position: relative; padding: 20px 94px 12px 180px; overflow: hidden; } .pgc-card::after { content: " "; display: block; border-left: 1px solid #e8e8e8; height: 120px; position: absolute; right: 76px; top: 20px; } .pgc-cover { position: absolute; width: 162px; height: 162px; top: 0; left: 0; background-size: cover; content { overflow: hidden; position: relative; top: 50%; -webkit-transform: translateY(-50%); transform: translateY(-50%); } .pgc-content- title { font-size: 18px; color: #222; line-height: 1; font-weight: bold; overflow: hidden; text-overflow: ellipsis; white-space: nowrap; } .pgc-content-desc { font -size: 14px; color: #444; overflow: hidden; text-overflow: ellipsis; padding-top: 9px; overflow: hidden; line-height: 1.2em; display: -webkit-inline-box; -webkit-line -clamp: 2; -webkit-box-orient: vertical; } .pgc-content-price { font-size: 22px; color: #f85959; padding-top: 18px; line-height: 1em; } .pgc-card -buy { width: 75px; position: absolute; right: 0; top: 50px; color: #406599; font-size: 14px; text-align: center; } .pgc-buy-text { padding-top: 10px; } .pgc-icon-buy { height: 23px; width: 20px; display: inline-block; background: url(https://s0.pstatp.com/pgc/v2/p gc_tpl/static/image/commodity_buy_f2b4d1a.png); } Children's breakthrough thinking training hole book ¥24.9 Buy this set of four books, namely "Guess What Taste", "Guess Who's Car", "Guess Who's Car" Guess What Color This Is" "Guess Who Eats It".
