如果母亲表达的情绪是儿童反社会行为问题的一个环境风险因素，那么即使在考虑了遗传对儿童行为问题的影响之后，也应该考虑在同一家庭中长大的兄弟姐妹之间的行为差异。这一假设在环境风险纵向双胞胎研究与全国代表性的1994-1995年出生队列的双胞胎进行了测试。作者采访了565对5岁的同卵双胞胎（MZ）的母亲，并确定每个家庭中哪一对双胞胎接受了更多的负面情绪表达，哪一对双胞胎接受了更多的温暖。在同卵双胞胎中，接受更多母亲消极和更少温暖的双胞胎有更多的反社会行为问题。定性访谈被用来产生关于为什么母亲对待他们的孩子不同的假设。研究结果表明，母亲对孩子的情感态度可能会在反社会行为的发展中发挥因果作用，并说明遗传信息研究如何为社会化假设的测试提供信息。
If maternal expressed emotion is an environmental risk factor for children's antisocial behavior problems, it should account for behavioral differences between siblings growing up in the same family even after genetic influences on children's behavior problems are taken into account. This hypothesis was tested in the Environmental Risk Longitudinal Twin Study with a nationally representative 1994-1995 birth cohort of twins. The authors interviewed the mothers of 565 five-year-old monozygotic (MZ) twin pairs and established which twin in each family received more negative emotional expression and which twin received more warmth. Within MZ pairs, the twin receiving more maternal negativity and less warmth had more antisocial behavior problems. Qualitative interviews were used to generate hypotheses about why mothers treat their children differently. The results suggest that maternal emotional attitudes toward children may play a causal role in the development of antisocial behavior and illustrate how genetically informative research can inform tests of socialization hypotheses.
