Several researchers (Dunn, 2006; Walker & Taylor, 1991) believe that one's moral code develops through social interaction—discussion, debate, perspective-taking, and emergence of consensus. Social interaction begins in the family, where children's needs, parental control, issues of reciprocity, fairness, rights, obligations, and the welfare of others are experienced regularly and negotiated between children, siblings, and parents. The family is also the setting in which children begin to learn the conventional and moral rules of their society. Such learning continues via social interaction in the school, peer group, and community.
