 Importantly, Piaget and Kohlberg also shared the view that over the course of development, normative reasoning emerges in stages. According to both Piaget and Kohlberg, in the first stage of this process young children’s view of morality is “heteronomous”—it is a set of rules imposed and enforced by others—and moral behavior is simply a matter of complying with rules set by adults.
