The moral judgment of 135 normal, educable retarded, and trainable retarded boys and girls (ages 6-10, 11-13, and 14-16) was individually assessed to determine the significance of chronological age and IQ on moral development. The results indicated significant differences in mean normal judgment between the groups and each age level. The findings were interpreted as substantiating Piaget's stage theory of moral development and suggesting that within the retarded population, level of intellectual ability is also significantly related to moral judgment.
对135名正常、可教育的智力迟钝和可训练的智力迟钝男孩和女孩（年龄在6 - 10岁、11 - 13岁和14 - 16岁）的道德判断进行了个体评估，以确定实际年龄和智商对道德发展的重要性。结果表明，各群体之间以及每个年龄水平的平均正常判断存在显著差异。这些发现被解释为证实了皮亚杰的道德发展阶段理论，并表明在智力迟钝人群中，智力水平也与道德判断显著相关。
