1. Gross movements

Gross movements are body activities and posture reactions, and are also the basis of human body activities. If gross motor development is good, it can promote brain development; if gross motor development is poor, it is often an early indicator of low intelligence, but it is not necessarily a case of dementia.

The main behavioral patterns appear at the following times: raising head 90 degrees: 3-4 months, turning over: 5-7 months, sitting: 10-12 months, walking: 11-12 months 15 months, running: around 24 months, jumping: around 30 months.

2. Fine movements

After 6 months of age, babies mostly "explore" their own bodies. Babies with normal intellectual development can still play with their hands between 6 and 12 months old. At this stage, babies can bend down to pick up objects far away from themselves, and can pass objects between their hands; they can also pick up food and chew it by themselves.

3. Adaptive ability

Adaptive ability refers to the ability to analyze and synthesize stimuli. It is inseparable from the development of vision, hearing, language and hand functions. , so it is also called corresponding energy. Adaptability is the prelude to intellectual development and can predict the quality of future intellectual development.

The emergence time of the main behavioral patterns is - being able to track objects with eyes: 1 month, being able to find the source of sounds: 4 months, finding lost toys: 6 months, and ringing bells consciously: 8 months , able to find things in the box: 10 months, put back the bottle cap: 12 months, close the lid of the round box: 15 months, recognize the size: 27 months, recognize the color red: 30 months, know the "inside", "Outside": 33 months.

4. Language ability

Language is a psychological activity unique to human beings. For example, children talk to each other, listen to music, songs, tell stories, sing songs, write, draw pictures, etc. These listening, speaking, reading and writing are all different forms of language activities. Language can promote the rapid development of children's psychological activities.

The main behavioral patterns appear at the following time - making slight guttural sounds: 1 month, talking to herself: 4 months, making da-da, ma-ma sounds: 7 months, barking Can turn head when naming: 7 months, knows welcome and goodbye: 10 months, consciously calls mom and dad: 12 months, can say more than one word sound: 18 months, can say more than two children's songs: 24 Months, able to speak long sentences of more than 10 words: 36 months.

5. Social behavior

Social behavior reflects children’s ability to socialize and take care of themselves. At 4 to 6 weeks after birth, the baby can follow moving objects with his eyes and turn 90 degrees in the horizontal direction; at 12 weeks, he will turn his head towards the mother when he hears the mother's voice; at 12 to 16 weeks, he will see his mother holding a bottle and preparing to give it to the baby. When he feeds, he opens his mouth and waits. If the child still cannot "follow people" with his eyes at 8 months, there may be abnormal intellectual development.

6. Sleep

As the baby grows up month by month, the time spent sleeping will gradually decrease and the time spent awake will gradually increase. If your baby sleeps for too long, or is drowsy throughout the day and night, his intelligence may not be optimistic.

7. Emotions

In fact, babies can smile unconsciously from more than a month after birth, but a truly emotional smile will not occur until the baby is 3 months old. If a baby loves to laugh, it means that he feels full of love and security, and his personality will become cheerful. Even if the baby is still in the period of birth, a baby who loves to laugh means that he has better intelligence.
