“…Paradis and Genessee (1996), in particular, have proposed that different types of interaction might occur: (1) transfer, when elements specific to one language are used in productions of the other language; (2) deceleration, when interaction between the two languages interferes with, and thus slows down, the rate of acquisition; and (3) acceleration, when interaction between two languages aids in, and thus speeds up, the acquisition process. Although this study has only found evidence of acceleration as pointed out above, it is not ruled out that transfer, acceleration, and deceleration might indeed occur at the same time for different language aspects (see, for instance, Goldstein, 2010b, andBarlow, 2010). Evidently, there is need for more research that examines the issue of interdependence in groups of bilinguals and trilinguals instead that in individual children.…”
