The brothers of 73 delinquent boys were found themselves to be more antisocial than the brothers of 73 matched control boys. Further, the average antisocial score of the probands' brothers increased with the number of brothers in the family, holding the number of sisters constant, and decreased with the number of sisters, holding the number of brothers constant. These results are interpreted in terms of male potentiation and female suppression of antisocial behaviour in boys. Results are also reported for 59 pairs of matched delinquent and control girls and their siblings.
研究发现，73名违法男孩的兄弟比73名匹配的对照男孩的兄弟更具反社会倾向。此外，先证者兄弟的平均反社会得分在姐妹数量保持不变的情况下，随着家庭中兄弟数量的增加而升高；在兄弟数量保持不变的情况下，随着姐妹数量的增加而降低。这些结果是根据男孩反社会行为的男性强化和女性抑制来解释的。文中还报告了59对匹配的违法女孩和对照女孩及其兄弟姐妹的研究结果。
