At what age does a baby's intellectual development complete?

Parents love smart babies, and mothers should pay more attention to their children's physical and mental development. So at what age is the baby's intellectual development complete? What should I do if my baby's intellectual development is delayed? The following editor will give you a detailed introduction.

At what age does a baby's intellectual development complete?

The development of children's intelligence is the result of the rich and colorful stimuli in the objective world acting on the brain. When a child is born, he is a piece of natural material, and his intelligence is almost a blank sheet of paper; as he grows older, his intelligence improves year by year. The period of the fastest intellectual development is from birth to two years old.

Scientists believe that, in most cases, intellectual development reaches its peak at the age of 17. After that, experience can be accumulated, knowledge can be improved, and judgment can be improved, but intelligence will not increase much.

Generally speaking, if the intelligence at the age of 17 is taken as 100%, then 50% of intellectual development is completed before the age of 4, 30% is completed between the ages of 4 and 8, and the remaining 20% ​​is completed between the ages of 8 and 17.

The development of intelligence, unlike the development of other aspects of the body, does not have a steep peak in pre-puberty, and the development of intelligence in childhood does not proceed in a stable straight line, but develops alternately, with periods of faster development and periods of slower development.

For some people this tendency is more obvious. At a certain stage their intellectual development may be significantly higher than that of normal children, but later on it gradually slows down and becomes not much different from ordinary people.

At the age of 25-35, intelligence test scores begin to decline, but overall, the decline is not obvious, it is relatively stable, and it lasts for a long time. In old age, intelligence gradually declines. After the age of 60, intelligence gradually declines.

Psychologists have found that the various elements of human intelligence reach their optimum at different ages and decline at different rates. For example, verbal ability usually only shows a slight decline at the age of 80.

For example, a person's short-term memory reaches its peak at the age of 11-12 and there will be no major progress thereafter, while long-term memory will continue to develop with age.

What to do if your baby has intellectual retardation

Visual stimulation method: There are colorful flowers in the garden. Parents can ask their children to find flowers of different colors, so that the baby will respond to the corresponding color words, thereby exercising intelligence. Of course, in addition to flowers, other things in the park, such as trees, birds, railings, etc., can be used as objects to search.

Auditory stimulation method: There are thousands of kinds of sounds in nature. Parents can use induction to let the baby focus on a certain sound, such as the sound of spring rain, the sound of cicadas in summer, the sound of autumn wind, or the simple sound of cats and dogs. These are all excellent sound stimulation. There are fewer animals in the city, but there are more modern tools, such as the sound of car startup, the sound of cranes for building houses, the sound of police cars, etc., which can also be used.

Tactile stimulation method: There are many things in nature, and each thing has its own specific shape. Parents can use these things to stimulate the baby's sense of touch.

Simulate "telephone conversation": Mom and Dad stand at a certain distance from the baby, and ask the baby what he is doing now, or what happened, just like making a phone call, and how the baby can solve such problems with his own ability. The more extensive the stimulating topics, the better. For example, if the baby encounters a caterpillar and is very scared, what should he do?

Exercise: Exercise can stimulate the baby's brain and cerebellum central nervous system to a certain extent, and will promote the baby's brain development to a certain extent. First of all, there should be a fixed goal, let the child run at his fastest speed, or parents can run with the child in the form of a competition, but the baby must win, which can arouse the baby's interest. Let the baby run back and forth until the baby is out of breath, which can increase the oxygen supply to the baby's brain, make the baby's brain more flexible and easy to use, coordinate the baby's body functions, and promote the development of the child's motor cells.
