The purpose of this study was to test the directionality of influence between reading comprehension (RC) and print exposure (PE), thereby estimating genetic and environmental effects of this relation. The sample consisted of 910 twins in fourth through ninth grades (M = 12.33 years, SD = 1.41) from the Florida Twin Project on Reading, Behavior, and Environment. Using direction-of-causation model in a twin design, results supported a direction of influence running from RC to PE. This relation was underpinned by genetic and environmental factors of RC as well as PE. Implications for reading education are discussed.
本研究旨在检验阅读理解（RC）和印刷品接触（PE）之间的影响方向，从而估计这种关系的遗传和环境效应。样本由来自佛罗里达阅读、行为和环境双胞胎项目的 910 对 4 至 9 年级的双胞胎（M=12.33 岁，SD=1.41）组成。使用 twin 设计中的因果关系模型，结果支持从 RC 到 PE 的影响方向。这种关系是由 RC 和 PE 的遗传和环境因素共同支撑的。讨论了对阅读教育的影响。
