What are the four stages from heteronomy to self-discipline?

The four stages from heteronomy to self-discipline are self-centeredness, authority, reversibility and justice.

Egocentric stage:

Also known as the pre-moral stage, children in this stage lack a sense of regulating their behavior according to rules, such as parent-child relationship, peer relationship, value judgment, etc., and will show a self-centered tendency.

Authority stage:

Or in heteronomous morality stage, children at this stage often show absolute obedience to external authority and regard the rules of authority as absolute and unchangeable.

Reversible stage:

That is, the initial stage of independent morality. At this stage, many children's thinking gradually becomes conservative and reversible, and they think that the rules can be changed, thus gradually changing from heteronomy to self-discipline.

Justice stage:

At this stage, children's concept of justice has developed to a certain extent, and their moral concept mainly tends to be just and fair.
