The four stages of self-discipline

1. The first stage is the "egocentric stage" or pre-moral stage (2-5 years old), in which children lack the consciousness to regulate their behavior according to the rules, and show egocentric tendency in parent-child relationship, peer relationship, and value judgment.

2. The second stage is the "authority stage" or other moral stage (6-7, 8 years old), in which children show absolute respect and obedience to the external authority, regard the rules determined by the authority as absolute and unchangeable, and evaluate their own behavior and the behavior of others based on the attitude of the authority.

3, the third stage for the "reversibility stage" or preliminary self-discipline moral stage (8-10 years old), the children's thinking at this stage of the constancy and reversibility, they no longer see the rules as a static thing, and gradually from the other to self-discipline.

4. The fourth stage is the "justice stage" or self-discipline moral stage (10-12 years old), the children in this stage after reversibility, the concept of justice or sense of righteousness has been developed, the children's moral tendency to preside over the fairness and equality.

Expanded:

Piaget believed that epistemological problems must all be biologically consideration. This is important from an epistemological point of view of occurrence, because psychogenesis can only be understood after its organic roots have been revealed.

In order to better explain the mechanism of biological evolution, Piaget used the biological theory of phenotypic reproduction to explain the occurrence and development of cognition, and to clarify the close relationship between the biological concept of the interaction between internal factors and the environment and the epistemological concept of the interaction between the subject and the object.
