Extended data:

Internalization refers to a transition, and as a result of this transition, the process of dealing with external forms of external material objects will be transformed into a process of wisdom and consciousness; In this case, they have undergone special transformation-generalization, verbalization and simplification, and the most important thing is that they can go beyond the boundaries of external activities and develop further.

the basic view of the theory of external Shuo (pronounced shuò) (environmental determinism) is that human development mainly depends on external forces, such as the stimulation or requirements of the environment, the influence of others and school education. It is a term about explaining the motivation of individual physical and mental development, as opposed to endogenous theory (genetic determinism).
