How to grasp the critical period of a person's intellectual development, Japanese psychologist Kuiyi Kimura's "Law of Decline" holds that if a person's potential ability is 100%, then his ability can reach 100% at birth, 80% when he starts education at the age of 5, and only 60% when he starts education at the age of 10. Psychological research shows that: "0 to 7 years old is the key period of human intelligence development." In other words, from the birth of a child, we should consider educating him. If you don't give your child proper stimulation and education, it will delay his intellectual development opportunities.
There is a critical period for human intelligence development, and developing children's language is the key to seize the best opportunity for education. Because the development of children's intelligence is first manifested in the development of language, which is an important basis for children's all-round intellectual development. Scientific research shows that 1 year-old is the best time for children to actively understand language; 2 to 3 years old is the best time to learn spoken English; 4 to 5 years old is the best time for children to learn written language. In early childhood, the vocabulary increased rapidly, about 3 ~ 4 times, that is, 800 ~1000 at the age of 3; At the age of 4, there was1600 ~ 2000; At the age of 5, there are 2200 ~ 3000; At the age of 6, there were 3000 ~ 4000. Language not only helps children think well, but also is a tool for them to master knowledge.
If a person's intelligence is not developed or suppressed at the best time, it is difficult to remedy it.
