});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.

For example, if they know the concept of "food", no matter what kind of vegetables they look like, they should be classified into one category. The classification of biology has also developed in this way. The earliest method is to identify and distinguish species according to phenotypic characteristics, and to classify them step by step according to the degree of phenotypic similarity, so as to establish a classification system that is easy to retrieve. This is the principle of phenotypic classification. However, the problem of phenotypic classification is that it is difficult to reveal the essential laws of things. Many creatures with very different shapes may have kinship relationships. For example, the online sentence "When I knew sunflowers belonged to Compositae, I collapsed" is what it means.
