Abstract

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.

摘要

在对特克海默、海利、沃尔德伦、多诺弗里奥、戈特斯曼二世(2003年,《社会经济地位改变幼儿智商的遗传力。心理科学》,14:623 - 628)的一项重复研究中,我们调查了839对双胞胎的认知能力中的基因 - 环境(G×E)相互作用,这些双胞胎在1962年完成了国家优秀学者资格测试。对于来自贫困家庭的青少年,共享环境影响更强,而对于来自富裕家庭的青少年,遗传影响更强。在父母收入和父母教育的交互作用方面未发现显著差异。结果表明,中上层家庭之间的环境差异会影响智力遗传潜力的表达,正如布朗芬布伦纳和塞西(1994年,《从发展视角重新概念化自然与养育:一种生物生态模型。心理评论》,101:568 - 586)的生物生态模型之前所表明的那样。
