in Kohlberg’s theory of moral development, the first level of moral reasoning, characterized by the child’s evaluation of actions in terms of material consequences. This level is divided into two stages: the earlier punishment and obedience orientation (Stage 1 in Kohlberg’s overall theory), in which moral behavior is that which avoids punishment; and the later naive hedonism (or instrumental relativist orientation; Stage 2), in which moral behavior is that which obtains reward or serves one’s needs. Also called preconventional morality. See also conventional level; postconventional level.
