Extended data:

In any case, trained children can surpass untrained children for a period of time, but after a certain age, once untrained children are given the same training, they will immediately catch up with or even surpass trained children.

This leads to a deeper conclusion: no matter how good the external education environment is, if the child does not reach that age, the effect will be minimal. The age mentioned here can be further considered as "gene". They believe that it is controlled by genes and cannot be changed by external forces, so it is determined by genes.

When a mouse is placed next to a 9-month-old child, the child shows great interest at first, but once he wants to reach out and touch the mouse, the experimenter will suddenly ring the iron bar to scare the child and repeat it many times. As a result, children get scared at the sight of mice.

From this, we can draw a conclusion: what kind of person do you want to cultivate your children? You should encourage your child with stimulation that is beneficial to that direction, cultivate him from an early age and form a habit. Their slogan is: "Give me a dozen healthy babies, and I can train them into any type of role I choose!" " "

The development of children's psychology is divided into four stages: 0-2 years old is the nastic movement stage, and children know the world through sports; 2-7 years old is the pre-operation stage, in which children mainly imitate and lack logical thinking and reasoning ability; 7- 1 1 year-old is the specific operation stage, and children initially form logical thinking; 1 1- 15 years old is the stage of formal operation, abstract thinking is gradually formed, and children have the ability to reason logically about assumptions.

The characteristic of this school is that they believe that children's psychological development is staged, not continuous.
