Bilingualism as a window into the language faculty: The acquisition of objects in French-speaking children in bilingual and monolingual contexts

Abstract

Where do the two languages of the bilingual child interact? The literature has debated whether bilingual children have delays in the acquisition of direct objects. The variety of methods and languages involved have prevented clear conclusions. In a transitivity-based approach, null objects are a default structural possibility, present in all languages. Since the computation of lexical and syntactic transitivity depends on lexical acquisition, we propose a default retention hypothesis, predicting that bilingual children retain default structures for aspects of syntactic development specifically linked to lexical development (such as objects). Children acquiring French (aged 3;0–4;2, N = 34) in a monolingual context and a French/English bilingual context participated in a study eliciting optional and obligatory direct objects. The results show significant differences between the rates of omissions in the two groups for both types of objects. We consider two models of how the bilingual lexicon may determine the timetable of development of transitivity.
