Language use and joint attention (JA) strategies were examined during interactions between francophone mothers and fathers and either their birth children (n = 10) or their internationally adopted children from China (n = 8), once when the children were 15 months old and again at 20 months, on average. Results showed that mothers engaged in more JA episodes and tended to talk more with their children than did fathers; however, this was influenced by the language-learning situation of the child. Specifically, the adoptive parents engaged more with their children than did the birth parents, and the behaviors of the internationally adopted mothers and fathers were more similar to each other than to those of the birth parents, arguably to support their children's unique language-learning situation. However, in contrast to a previous study that examined JA with adoptive mothers, the adoptive fathers' interaction styles with their children at 15 months were not related to children's vocabularies at 20 months as has been observed for mothers.It is becoming increasingly evident that the nature and quantity of input children are exposed to during early language acquisition can play an important role in their language development and even ultimate attainment (e.g., Hoff, 2006). In particular, it has been found that input during episodes of joint attention (JA) between children and their parents plays a role in children's early language learning (e.g.,
