Final answer:
Lawrence Kohlberg proposed three stages of moral development: preconventional, conventional, and postconventional.
Step-by-step explanation:
According to Lawrence Kohlberg, there are three stages of moral development: preconventional, conventional, and postconventional.
In the preconventional stage, young children make moral decisions based on punishment and reward. In the conventional stage, individuals conform to society's norms and rules.
In the postconventional stage, moral decisions are made based on universal ethical principles.
Kohlberg's theory of moral development suggests that individuals progress through these stages as they mature and gain cognitive abilities.
