Effect of time of exposure to L2 on the comprehension of relative clauses in primary school children

This study investigates the impact of second language age of onset on the development of syntactic competence in bilinguals. Forty-five bilingual children were tested using a picture- matching task with relative clauses. In this paradigm, children are aurally presented with relative clauses of various kinds and are asked to match what they hear with the appropriate picture (out of four choices) on the screen. More specifically, our experiment compared the comprehension of subject- vs. object-extracted center-embedded relative clauses and contained sentences with noun phrases (NPs) that did or did not match in number (both NPs singular or plural = match, one NP singular, one NP plural = mismatch). We compared the performance of a group of Simultaneous bilinguals (two languages since birth), Early sequential bilinguals (first exposure to L2 - English between the ages of 1 to 4) and Late sequential bilinguals (first exposure to L2 -English after the age of 4 but latest at the age of 6 - primary school). The mean age of the participants at the time of testing was approx. 10 years of age. The results show that there is a varied pattern in the comprehension strategies used among the three bilingual groups. The group of Simultaneous bilinguals showed more reliance on the syntactic information contained in..
