Role-taking ability and level of moral development were measured in three groups of boys and girls including 16 moderately retarded adolescents (mean chronological age 15; mean mental age 9), 16 nonretarded adolescents matched for chronological age, and 16 nonretarded children matched for mental age. The mentally retarded adolescents scored significantly lower on role-taking ability and moral development than the adolescents matched for chronological age. They did not differ from children of their same mental age in role-taking ability; and they tended to score lower in moral development. The results supplied qualified support for Kohlberg's theory of moral development.
研究测量了三组男孩和女孩的角色采择能力和道德发展水平，这三组包括16名中度智障青少年（实际年龄平均为15岁；心理年龄平均为9岁）、16名实际年龄匹配的非智障青少年，以及16名心理年龄匹配的非智障儿童。与实际年龄匹配的青少年相比，智障青少年在角色采择能力和道德发展方面的得分显著更低。他们在角色采择能力上与相同心理年龄的儿童没有差异；并且他们在道德发展方面的得分往往更低。这些结果为科尔伯格的道德发展理论提供了有限的支持。
