The research on classification ability is more in kindergartens and more in primary schools. 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 ability of children aged 1-3 has begun to sprout, but the concept of "category" has not yet formed. 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. They will divide the balls and apples together, either according to the shape (circle) or according to the color (red), but they will not put apple kernel bananas together according to the function (edible).
