Characteristics of children's physical and mental development
Children's cognitive development is mainly reflected in three aspects: perception, thinking and behavior. In terms of perception, children begin to know their bodies and the world, and learn to perceive and react. In terms of thinking, children begin to develop their ability to understand and analyze things, and begin to use logical thinking and creative thinking to solve problems.
In terms of behavior, children learn to express themselves and interact with others, and also begin to explore and discover the connections and laws between things. Cognitive development is the basis of children's physical and mental development, and it is also an important basis for children's follow-up learning and growth.
One of the characteristics of children's physical and mental development is their rapid physical development. In preschool children, children's physical function began to improve gradually, and their muscle strength, coordination and endurance were significantly improved. The rapid development of the body means that children can walk, run and jump independently. The development of these movements is very important for children's balance and coordination.
