Indeed, Xiaoqu once saw similar information on the Internet, saying that mothers have a greater influence on children's intelligence, especially on the intellectual inheritance of male babies.
Is this statement true or false?
Is it true that IQ is inherited from mother?
Where do intelligence genes come from? According to an article in Psychological Scene, it says that "smart people should thank their mothers" because according to researchers, their mothers are mainly responsible for passing on intelligence genes.
Scientists believe that children's intelligence genes are more likely to be inherited from their mothers because they are located on the X chromosome-women have two X chromosomes and men have only one.
For many years, some researchers of the Medical Research Council in Glasgow, Scotland have been studying this. Through ten years' research, it is found that a mother's IQ is the best index to predict a child's intelligence. The researchers interviewed 12686 young people aged 14 to 22, and found that the average IQ difference between children and mothers was only 15.
Therefore, a child's intelligence is related to the mother's genes. Especially for boys, their only X chromosome comes from their mother, so in theory, the mother's genetic effect on their son's intelligence is very important.
Heredity is only part of IQ.
Scientists have found that genes are not the only factor that affects IQ, and the acquired growth environment is equally important for human intelligence training. According to research, only 40% to 60% of human intelligence is related to heredity, and the rest is related to environmental factors.
Generally speaking, we say that mothers have a greater influence on children's IQ because mothers also play a considerable role in non-genetic aspects in the environment of acquired IQ growth.
The University of Washington once conducted a survey. By observing the way a group of mothers and children get along for seven years, the researchers confirmed that the emotional connection between mother and child is very important for the growth and development of some parts of the child's brain. The hippocampus of children who are emotionally supported and satisfied is larger than that of children who are emotionally alienated from their mothers 10%, and the hippocampus is related to learning, memory and stress response.
In the process of children's growth, it is precisely because their mothers give them more sense of security that they can better understand and perceive the world and further stimulate their intellectual potential.
In addition, because family education plays an irreplaceable role in the IQ development of children after birth, and mothers bear a large part of the responsibility of pregnancy, the education received by mothers with higher cultural literacy will be more powerful. They either pay attention to children's intellectual education, or exert a subtle influence on children through their own learning and supplement.
It can be seen that there is a scientific basis for children's IQ to be inherited from their mothers, but this statement is not completely accurate. With the development of modern living conditions and science and technology, many children with average IQ can gradually develop higher IQ under the guidance of good education the day after tomorrow.
IQ is not a serious injury. Parents can exercise their children through reading, games and study, create a rich growth environment for their children, constantly tap their new potential, and let them grow into their own "genius"!
