Bruner, a famous American psychologist, tracked and investigated 1000 children. He later thought that if the intelligence reached at the age of 17 is regarded as 100, then it has been 50% from birth to 4 years old; From the age of 4 to 8, I got 30% of them; In fact, from the age of 8 to the age of 17, only 20% of the intelligence was obtained. Although this is his opinion, one thing has been affirmed by psychologists at home and abroad, that is: early education is very important!
There are "prodigies" and relatively speaking, there are also "fools". A "stupid child" is an imbecile, which is medically called mental retardation. There are many reasons for low energy, and some methods to treat low energy have also achieved results. Low energy is not synonymous with "uselessness".
You know, many "stupid children" are not "stupid". Some so-called "stupid children" have normal brain physiology, but due to improper education or other reasons, their intelligence development is slow in some aspects. Such children, with a good education, can grow up healthily and even become talents who have made outstanding contributions to society.
