2003年，社会经济地位改变了幼儿智商的遗传性。心理学，14：623-628)，我们研究了839对双胞胎在认知能力上的基因-环境(G×E)交互作用，这些双胞胎在1962年完成了国家功绩资格考试。对于来自贫困家庭的青少年来说，共同的环境影响更强，而对于来自富裕家庭的青少年来说，基因影响更强。父母收入和父母教育交互效应之间没有显著差异。结果表明，中上层家庭之间的环境差异影响了智力遗传潜力的表达，正如Bronfenbrenner和Ceci(1994，自然-养育在发展视角下重新概念化：生物生态学模型心理学评论，101：568-586)生物生态学模型所提出的那样。
In a replication of Turkheimer, Haley, Waldron, D'Onofrio, Gottesman II (2003, Socioeconomic status modifies heritability of IQ in young children. Psychological Science, 14:623-628), we investigate genotype-environment (G x E) interaction in the cognitive aptitude of 839 twin pairs who completed the National Merit Scholastic Qualifying Test in 1962. Shared environmental influences were stronger for adolescents from poorer homes, while genetic influences were stronger for adolescents from more affluent homes. No significant differences were found between parental income and parental education interaction effects. Results suggest that environmental differences between middle- to upper-class families influence the expression of genetic potential for intelligence, as has previously been suggested by Bronfenbrenner and Ceci's (1994, Nature-nurture reconceptualized in developmental perspective: a bioecological model Psychological Review, 101:568-586) bioecological model.
