Kohlberg's Theory of Moral Development is a theory that focuses on how children develop "morality" and "moral reasoning". Kohlberg's theory suggests that moral development occurs in three-level and each level has two stagesThe theory also suggests that moral logic is primarily focused on seeking and maintaining justice. It is based on the idea of Jean Piaget about children's righteous judgment.Stages of Moral Development: Kohlberg's theory is broken down into three primary levels. At each level of moral development, there are two stages.Level 1. Preconventional Morality (4 to 10 years): Preconventional morality is the earliest period of moral development. At this age, children's decisions are primarily shaped by the expectations of adults and the consequences of breaking the rules. There are two stages within this level:Stage 1 (Obedience and Punishment): Children at this stage see "rules as fixed and absolute". Obeying the rules is important because it is a way to avoid punishment. In this children ignore the intention of others and instead focus on the fear of authority and negative consequences. Stage 2 (Instrumental purpose and exchange): At the individualism and exchange stage of moral development, children account for individual points of view and judge actions based on how they serve individual needs. Level 2. Conventional Morality (10 to 13 years): The next period of moral development is marked by the acceptance of social rules regarding what is good and moral. During this time, adolescents and adults internalize the moral standards they have learned from their role models and from society.Stage 3 (Good-Boy Good-girl orientation): This stage of the interpersonal relationship of moral development is focused on living up to social expectations and roles. There is an emphasis on conformity, being "nice" and consideration of how choices influence relationships.Stage 4 (Social concern and conscience): This stage is focused on ensuring that social order is maintained. The focus is on maintaining law and order by following the rules, doing ones duty, and respecting authority.Level 3. Postconventional Morality (13 to 16 years): At this level of moral development, people develop an understanding of abstract principles of morality. The two stages at this level are:Stage 5 (Social Contract and Individual Rights): At this stage, the people believe that rules of law are important for maintaining a society, but members of society should agree upon these standards.Stage 6 (Universal Ethical Principles): Kohlbergs final level of moral reasoning is based on universal ethical principles and abstract reasoning. At this stage, people follow these internalized principles of justice, even if they conflict with laws and rules.Hence, we can conclude that social concern and conscience is a sub-stage in Kohlberg's 'conventional state's of Moral Development.
