“…Assuming that variation in input conditions will affect language development, researchers have asked the following question: How robust or sensitive is morphosyntactic acquisition in the face of dual‐language learning? This question has been addressed from both constructivist and generative theoretical perspectives, focusing on both rates and patterns of acquisition (Gathercole, 2007; Müller & Hulk, 2001; Nicoladis, Palmer, & Marentette, 2007; Paradis, Nicoladis, & Crago, 2007; Pérez‐Leroux, Pirvulescu, & Roberge, 2009). This study is concerned with the impact of dual‐language learning on children's rate of morphosyntactic acquisition.…”
