In the 20th century, an American psychologist named Lawrence Kohlberg developed a model that explained how individuals develop morality. This model is known as Kohlberg's Stages of Moral Development. Kohlberg's model is composed of three stages, each of which includes two phases. The three stages are preconventional morality, conventional morality and postconventional morality.
Kohlberg observed that children advance through what he believed to be definite stages of moral development in a manner similar to their progression through Piaget s (1977) two-stage theory of cognitive development which Kohlberg studied as a graduate student at the University of Chicago.niversal moral principles Kohlberg believed that individuals could only progress through these stages one stage at a time. This view contrasted with Maslow s (1943, 1968, 1972) hierarchy of prepotent needs because human beings, according to Kohlberg, could neither skip stages nor return to any previous stage.
