Some psychologists divide children's learning ability into two levels from the perspective of educational sociology. The first level of ability belongs to associative ability, which generally refers to the memory and recognition of daily things. This level of ability is a basic ability that every child has (that is, there is no difference in social class). The second level of ability is conceptual ability, which usually refers to the ability to understand, think and judge things. It is a higher level of ability: this kind of ability is not inherent in every child, but related to the social and cultural environment in which children live, and usually needs to be cultivated through school education.
