The home literacy environment ( HLE ) predicts language and reading development in typically developing children; relatively little is known about its association with literacy development in children at family-risk of dyslexia. We assessed the HLE at age 4 years, precursor literacy skills at age 5, and literacy outcomes at age 6, in a sample of children at family-risk of dyslexia ( n = 116 ) and children with no known risk ( n = 72 ). Developmental relationships between the HLE and literacy were comparable between the groups; an additional effect of storybook exposure on phoneme awareness was observed in the family-risk group only. The effects of socioeconomic status on literacy were partially mediated by variations in the HLE; in turn, effects of the HLE on literacy were mediated by precursor skills ( oral language, phoneme awareness, and emergent decoding ) in both groups. Findings are discussed in terms of possible gene–environment correlation mechanisms underpinning atypical literacy development.
