Final answer:
Lawrence Kohlberg developed a theory of moral development that includes three levels: preconventional, conventional, and postconventional.
Step-by-step explanation:
In his theory of moral development, Lawrence Kohlberg identified three levels of moral reasoning: preconventional, conventional, and postconventional. In the preconventional stage, young children make decisions based on their own self-interest and the fear of punishment. In the conventional stage, individuals begin to consider the expectations and norms of society when making moral judgments. Finally, in the postconventional stage, people develop abstract reasoning skills and base their morality on personal ethics and principles, rather than conforming to societal norms.
