研究背景本研究旨在对7岁、12岁和16岁儿童的阅读表现进行CAP亲子相似性的首次分析，并评估16岁儿童阅读表现个体差异的病因。12岁和16岁，以及他们的养父母和非养父母时，儿童7岁。结果在收养家庭的亲子相关性在任何年龄都不显着，但非收养控制父母和他们的后代之间的相关性在所有三个年龄都是显着的。结论从父母和他们的孩子的数据的行为遗传模型拟合分析得到的结果在16岁时测试的结果与双胞胎和兄弟姐妹的研究结果一致，表明阅读能力的个体差异主要是由于遗传影响。与此相反，从父母到后代的环境传递是可以忽略不计的，这表明环境对儿童阅读表现的个体差异的影响在很大程度上独立于父母的阅读表现。
BackgroundThe study aimed to conduct the first analysis of CAP parent–offspring resemblance for reading performance in children aged 7, 12 and 16 years, and to assess the etiology of individual differences in reading performance of children at 16 years of age.MethodThe Reading Recognition subtest of the Peabody Individual Achievement Test was administered to children in the Colorado Adoption Project (CAP) at 7, 12 and 16 years of age, and to their adoptive and nonadoptive parents when the children were 7 years of age.ResultsResulting parent–offspring correlations in adoptive families were not significant at any age, but correlations between scores of nonadoptive control parents and their offspring were significant at all three ages.ConclusionsResults obtained from behavioral genetic model‐fitting analyses of data from parents and their children tested at age 16 are consistent with results of studies of twins and siblings indicating that individual differences in reading performance are due substantially to genetic influences. In contrast, environmental transmission from parents to offspring was negligible, suggesting that environmental influences on individual differences in the reading performance of children are largely independent of parental reading performance.
