 Elliot Turiel (1938–) was a student of Lawrence Kohlberg (1927–1987), who was, in turn, influenced by the work of Jean Piaget (1896–1980). All three have done seminal work on moral development in children and adolescents, and all three share the view that reasoning and reflection on one’s own experience plays a central role in that process. This view, often called  “constructivism”,[5]  is commonly contrasted with nativist accounts of moral development that focus on the role of the child’s innate endowment, and with social learning accounts that emphasize the process of acquiring moral principles from parents and other important people in the child’s environment (Killen &amp; Smetana 2015: 705–709; Killen &amp; Dahl 2018: 23–25).
