individualism and exchange

Explanation:

Lawrence Kohlberg has given the theory of moral development that consists of three different stages and each stage consists of two sub-stages or levels. The three stages are preconventional, conventional, and postconventional. Kohlberg's theory carries the different stages of moral reasoning which are the basis of an individual's ethical behavior.

The child feels free in making choices or carry on with his or her interests and considers punishment as a risk that needs to be avoided.
