Abstract: This study investigated the potential moderating role of genetic predisposition for language performance on the association between various environmental variables and children’s receptive and expressive language performance. Participants included 1150 preschool-aged monozygotic and dizygotic twins from the Early Childhood Longitudinal Study- Birth Cohort (ECLS-B). Hierarchical multiple regression analyses were conducted to explore interaction effect between genetic predisposition for language and singular environmental variables, genetic predisposition for language and indices of environmental risk and advantage, and genetic predisposition for language, indices of environmental risk and advantage, and gender. Findings provide tentative support for the interaction of genetic predisposition and environmental factors as a contributor to language performance. Three gene–environment interaction terms were found to be significant predictors of language performance. One two-way interaction and one threeway interaction were found to significantly contribute to their respective models’ ability to account for variance in children’s language performance.
