Research by cognitive psychologists has found that children under 0-1 years old basically have no classification ability, and they mainly rely on individual perception.

The classification of children aged 3-5 is basically still based on external perceptible dimensions such as shape and color. For example, children in small classes in kindergartens are asked to classify red plastic balls, red apples and bananas.
