“…For example, previous research has documented continued growth of the L1, although at a slower pace than in monolingual children (e.g., Jia, Strange, Wu, Collado, & Guan, 2006), levelling off in L1 proficiency (e.g., Kan & Kohnert, 2005), and even regression of L1 ability (e.g., Francis, 2005). With respect to L2 development, consistent growth of L2 vocabulary patterns has been found across studies (August et al, 2006;Bialystok et al, 2010;Kan & Kohnert, 2005;Kohnert, Windsor, & Ebert, 2009;Uchikoshi, 2006). However, at the beginning of primary school, the L2 vocabulary size of children from cultural minorities in the Netherlands who learn L2 Dutch, the focus group of the current study, is smaller than the estimated L1 vocabulary size of age-matched Dutch monolingual children.…”
