Dr. Tamara Sorenson Duncan in collaboration with Dr. Johanne Paradis (University of Alberta) recently published an article in the Journal of Child Language about the relation between children’s emerging L2 (English) abilities and the L2 input they receive at home. Using hierarchical linear regression modelling with controls for age, non-verbal reasoning and phonological short-term memory, this paper found that greater L2 input from siblings – but not mothers – was associated with stronger L2 abilities in narrative macrostructure, inflectional morphology, and vocabulary. Increased cumulative exposure to the L2 at school and greater maternal L2 fluency were also positively related to children’s L2 inflectional morphology and vocabulary scores.  Read online.
