The current study involved 281 early-school-age twin pairs (118 monozygotic, 163 same-sex dizygotic) participating in the ongoing Western Reserve Reading Project (S. A. Petrill, K. Deater-Deckard, L. A. Thompson, & C. Schatschneider, 2006). Twins were tested in their homes by separate examiners on a battery of reading-related skills including phonological awareness, rapid automatized naming, word knowledge, and phonological decoding. Results suggested that a core genetic factor accounted for a significant portion of the covariance between phonological awareness, rapid naming, and reading outcomes. However, shared environmental influences related to phonological awareness were also associated with reading skills.
当前的研究涉及281对学龄早期双胞胎(118对同卵双胞胎,163对同性异卵双胞胎),他们参与了正在进行的西储阅读项目(S. A. 佩特里尔、K. 迪特尔 - 德卡德、L. A. 汤普森和C. 沙茨施耐德,2006年)。由不同的考官在双胞胎家中对他们进行一系列与阅读相关技能的测试,这些技能包括语音意识、快速自动命名、词汇知识和语音解码。结果表明,一个核心遗传因素在语音意识、快速命名和阅读成绩之间的协方差中占很大比例。然而,与语音意识相关的共享环境影响也与阅读技能有关。
