What are the factors that affect children's IQ? In many families, children are put first. In the face of difficult problems, children can seek help from their parents. The solution of these problems is helpful to the development of their abilities. All parents should attach importance to the education of their children. Let me share the factors that affect children's IQ.

What are the factors that affect children's IQ? 1 Is the child's IQ inherited from his father or mother?

Intelligence is inherited to a certain extent, and it is also influenced by acquired factors such as environment, nutrition and education.

According to scientists' assessment, the influence of heredity on intelligence accounts for about 50%-60%. As far as heredity is concerned, mothers are smart, and most of the children born are smart. If they were boys, they would be smarter. The reason is that the genes related to human intelligence are mainly concentrated on the X chromosome, and women have two X chromosomes, while men only have 1, so the mother's intelligence occupies a more important position in heredity.

Boys are XY, so boys' IQs are all inherited from their mothers, and girls are XX, so half of girls' IQs are influenced by their fathers and mothers.

Because the IQ of girls is influenced by both father and mother, there will be a neutralization effect. Therefore, the distribution of girls' IQ will show a natural distribution, which is an inverted bell shape, with the most in the middle and less on both sides.

Factors affecting children's IQ

1, IQ congenital only accounts for 30% ~ 40%.

Joint research results of the University of Pittsburgh and Carnegie Mellon University. The researchers counted the data of more than 50,000 people collected in the previous 2 12 surveys on intelligence in the United States, and made in-depth analysis, and reached a surprising conclusion. That is to say, the influence of genetic factors on intelligence is only 30 ~ 40%. This is also an important statistical result, which proves that genetic factors are not important factors in determining intelligence. This result also proves from the opposite side that a good mother's internal environment and acquired environment can make anyone have a smart child.

2. Malnutrition will affect IQ.

Some people have done research on Korean orphans adopted by the American middle class before the age of 3 and between the ages of 3 and 5. Malnutrition was common before adoption, and the nutritional status was greatly improved after adoption.

The results show that early malnutrition can affect the IQ of children aged 1 1- 12. The IQ gap between well-nourished and malnourished children can reach 10, which is equivalent to the gap between high school and college. At the same time, the earlier the nutritional status improves, the better the IQ development. The IQ of children adopted before the age of 3 is significantly higher than that of children adopted after the age of 3.

3. Children with good living environment have high IQ.

British scholars have observed that babies living in noisy environment have low ability to imitate adult posture and understand size, size, distance and direction, and they are also backward in learning to speak at the age of 2. It has been suggested that a quiet environment is conducive to brain development. Japanese scholars believe that fragrance can improve intelligence after 1 year observation. Children living in fragrant environment have certain advantages in vision and receptive learning ability. In addition, family harmony and harmonious relationship between husband and wife also contribute to the development of children's IQ.

4. A child's IQ is related to the brain development in the fetal stage.

Scientific research has found that the fetus produces 654.38+million brain cells every minute, mainly in the first five months of pregnancy.

After children are born, they receive various stimuli and information through the senses such as eyes and nose, and convert them into various enzymes and chemicals, which are stored and utilized in the brain. A well-developed brain is very sensitive to these stimuli and information. This requires very active brain cells.

It is worth noting that brain cells will divide and reproduce repeatedly during the fetal period, but these activities will stop after birth. In other words, the number of nerve cells he used in his life was determined in the fetal period. Therefore, the degree of brain activity in the fetal period will affect the intelligence of children throughout their lives.

What are the factors that affect children's IQ? 2 Six factors that affect children's IQ.

Heredity: Generally speaking, if parents have high IQ, their children's IQ will not be low. This genetic factor is also manifested in blood relationship. Parents are local, and the average IQ of children is 102. The IQ of children born of parents married in different provinces is109; Parents are cousins, and the number of children with low IQ has increased significantly.

Breast milk: Breast milk contains many active substances that promote children's intellectual development, especially taurine, which has an important impact on intellectual development, which is 10 times higher than milk. According to the survey, the IQ of children who grow up with breast milk is about 3- 10 higher than that of children who grow up with milk substitutes.

Diet: Children who eat too much meat or eat too much will have decreased intelligence. The intelligence of children who skip breakfast will be affected, because protein, sugar, vitamins and trace elements in breakfast are all important components of brain health.

Obesity: Children who weigh more than 20% of normal children will have lower vision, hearing and ability to accept knowledge. This is because too much fat in obese children enters the brain, which will hinder the development of nerve cells and the proliferation of nerve fibers.

Environment: Children who live in boring environment, such as abandoned babies, can't get maternal love and good education, and their IQ will be lower. According to the survey, the average IQ of such children at the age of 3 is only 60.5, while the average IQ of 3-year-olds with good environment is 9 1.8.

Drugs: Some drugs can affect children's intelligence. For example, taking antiepileptic drugs for a long time will make its IQ low, and it will improve after stopping taking drugs for a few years.

Improve IQ and find a way together.

Prenatal education stimulates development

The fetus will feel it in about 3 months. When the mother touches the abdominal wall, the fetus will respond by kicking. By 4 months, the fetus will be aware of external sounds and feel any sound that can pass through the mother. This is because the ability of human blood to transmit sound waves is much greater than that of air. This kind of sound constantly stimulates the fetal sensory organs and promotes their development, which plays an important role in the development of human intelligence. By 5-6 months, the structure of fetal cerebral cortex has basically formed, and the sense of touch, vision, hearing and taste has developed to a considerable extent, and some activities of the outside world can be felt. At this time, playing some music and giving pregnant women prenatal education such as abdominal massage can promote the intellectual development of the fetus.

Alkaline food is good for children.

Human body fluids are slightly alkaline, which is beneficial to the absorption and utilization of substances. If children lack alkaline substances, it will affect hormone secretion and nerve activity, and such children have low IQ. It can improve children's diet structure, and eating more alkaline food can improve academic performance.

Generally speaking, green vegetables, nuts, fruits, low-fat milk, all kinds of mushrooms, beans and bean products, kelp and so on. They are all alkaline foods. Meat, fish, flour, rice and peanuts, such as pigs, cattle, sheep, chickens and ducks, are all acidic substances after human metabolism, so they belong to acidic substances.

Some foods, such as walnuts, frogs, pearls, animal brains and red dates, can enhance intellectual development. Foods with high vitamin C content are also beneficial to improve IQ. When orange juice with high vitamin C content was supplied to children 18 months, their IQ was 3.6 higher than that of users on average.

Caressing and nurturing promote growth.

Touching your baby gently can promote your baby's growth and development. We should massage the baby's head, neck, chest and limbs three times a day and touch the baby's whole body for 15 minutes every day for more than 10 days.

Enhancing children's memory depends on their usual efforts. Parents should often chat with their children, sometimes say a short sentence, and then let the children say it backwards. When walking, let the children remember the names of the shops and roads they pass by, and then recite them to see how much they can remember.

Books are an excellent means to improve children's intelligence, and colorful pictures, such as a dog, an apple, a pen, etc. , should be chosen for babies under 1 year. Use pictures to let them know what they can't see or connect with what they can see. 1-2-year-old children should choose books with large pictures and words, which can reflect things they are familiar with, such as flowers and animals.

House, etc. , and associated with words. For children aged 2-3, choose a picture book with story content, and cooperate with children's songs that can be read together. For 3-4-year-old children, we should choose books with new ideas and more details, such as animal stories, short fairy tales and short Tang poems. Although you don't know them very well, they are also good for enhancing your memory. When telling stories to children, children should be encouraged to ask questions and interrupt to improve their interest in learning.
