Hello everyone, if you don’t know much about intellectual development, it doesn’t matter. Today, this website will share with you the knowledge of intellectual development, including how old is the human IQ to be fully developed? The problems will be analyzed for everyone, and I hope we can solve everyone\’s problems. Let\’s get started!

1. Intellectual development standards for 3-year-old children
1. In terms of gross exercise, a 3-year-old baby can alternately go up and down stairs, stand on tiptoes, and can also stand on one foot. Long jump, there is also a feeling of wanting to jump high;
2. In terms of fine motor skills, a 3-year-old baby can imitate drawing crosses, circles, and shapes;
3. In terms of language, language has 6 directions. A 3-year-old baby can say its own name, complete sentences and its own gender, as well as Understand the concepts of you, me, and him;
4. In terms of cognition, a 3-year-old baby can at least distinguish between long and short, front and back, and can also count. Numbers, able to count to 1, 2, 3;
2. Original scoring standards for children\’s intelligence
Children\’s intellectual development is evaluated based on developmental quotient (IQ). According to the score of the intelligence test, a score above 85 is normal and a score below 85 is abnormal. Infants and young children, that is, children less than 3 years old, use the Gesell Developmental Scale to measure their developmental quotient. If the child is older than 3 years old, the Wechsler method is generally used to determine the child\’s IQ. An IQ below 85 is considered mental retardation. Mental retardation is divided into four levels: mild retardation, moderate retardation, severe retardation and extremely severe retardation. The clinical manifestations of these four levels are different, as follows:
1. Children with mild mental retardation have slightly lower understanding, will have language responses, and can understand conversations slightly less well;
2. Compared with mild mental retardation, moderate mental retardation has poorer understanding, slower language development, or unclear articulation, that is, unclear speech;
3. The score of severe mental retardation is lower, the child has poor understanding, insufficient cooperation, and backward language development, commonly known as an idiot;
4. Extremely Severe depression means a complete lack of understanding, inability to look at people, and normal communication. If it is a child under 3 years old, the measurement method is different, and it is called a low developmental quotient. These children generally have delayed language, cognitive backwardness, and problems. Poor vision, communication and understanding, lack of normal interaction
Intellectual development standards for children aged 3 to 16
1. There is no fixed value for what the IQ of a 16-year-old should be. It is usually between 70 and 130, and the average value is about 100. Therefore, the average IQ of a 16-year-old is around 100. is normal.
2. The intelligence test scale includes three stages: adults over 16 years old, children 6-16 years old and preschool age 4-6 years old. The result is called IQ. Normal people\’s IQ is usually between 90 and 109.
4. Principles of brain development
1. Brain development is a complex process. The following are some basic principles:
2. Cell proliferation: in the brain During the early stages of development, large numbers of neurons and glial cells are produced through cell proliferation.
3. Cell migration: During brain development, neurons and glial cells need to move from their origin to their final destination. This process involves the degradation of extracellular matrix and the action of molecules that promote cell migration.
4. Synapse formation: The connection between neurons is achieved through synapse formation. During the development of the brain, new neurons are continuously generated. , and they need to establish connections with other neurons to functionSexual neural network. This process involves the specific recognition and signaling of presynaptic and postsynaptic neurons.
5. Neuron differentiation: Different types of neurons have different shapes, functions and connections. During brain development, neurons need to differentiate into different types and form specific connections
5. How old is the human IQ to be fully developed?
Our human body’s IQ will not be fully developed, but our brain usually completes 60% of its development after three months of pregnancy. Our children will have completed about 80% of their brain development before they are 3 years old, and our children will have completed about 90% of it before they are 6 years old. Our children will basically have it all completed by the age of 13. The development and improvement of our human IQ is accompanied by human beings throughout their lives. As long as we have education, it is possible to improve our IQ.
Sixth and 18-month intellectual development standards
1. The intellectual development of 1-month-old babies can be mainly divided into motor ability, language ability, social ability, etc. At 18 months old, babies begin to learn to hold a spoon to eat, take off shoes and socks, etc., and they can also use a lot of paper, colored pens or crayons to draw.
2. Babies basically master 50-100 words, and 50% of babies master 60-80 spoken vocabulary. He would use two-letter sentences and start using three-letter sentences.
3. The baby can also imitate adults\’ speech and understand praise. The baby will be very happy and will often lose his temper when frustrated.
This is the end of the introduction about intellectual development and the age at which human IQ is fully developed. Did you find the information you need? If you want to know more about this, remember to bookmark and follow this site.
