This paper explores the role played by cognitive and processing limitations in language acquisition and the relevance of bilingual rst language acquisition for the ongoing debate on the ontogeny of functional categories. 1 Deening bilingual rst language acquisition Over the past twenty years the eld of language acquisition studies has beneetted enormously from the shift from an English-centred ...

We previously reported that inhibition of endosomal/lysosomal function can dramatically enhance human immunodeficiency virus type 1 (HIV-1) infectivity, suggesting that under these conditions productive HIV-1 infection can occur via the endocytic pathway. Here we further examined this effect with bafilomycin A1 (BFLA-1) and show that this enhancement of infectivity extends to all HIV-1 isolates...

Although evidence is now available from several domains of language acquisition research that bilingual (BFLA) children differentiate their languages from the time of their earliest productions, studies in the phonetics-phonology domain have been sparse until recently. In this paper we first highlight some methodological issues that impact phonetic phonological data collection and interpretatio...

The proposed project involves the design and implementation of a novel computational model of simultaneous acquisition of two languages from birth, or bilingual first language acquisition (BFLA). More specifically, we explore computationally the theory of Phonological Bootstrapping (Christophe et al. 1994, Christophe and Dupoux 1996, Morgan and Demuth 1996, Christophe et al. 1997), working with...

one of the most controversial and unresolved questions in bilingual first language acquisition (henceforth bfla) is whether bilingual children develop one mixed or two independent linguistic systems. many scholars in the lield of bfla arc in tavor of the one-system hypothesis (leopold 1970; swain and wesche, 1975; volterra and tacschner, j 987; grosjean, 1982; tacschncr, 1983: mclaughlin, 1984:...

The bilingual child does not fuse the two languages to which she is exposed; rather, in each language, most of the milestones she reaches, and even most of the errors she makes, align neatly with those of a monolingual acquiring that language. Hence it is generally agreed that the bilingual child acquires two separate grammars (e.g., Meisel, 1989, Genesee et al., 1995). Yet this separation does...

One of the basic questions of bilingual research is to what extent the bilingual’s two phonetic systems influence each other, a question that has occupied a prominent place in bilingual research almost from the outset of the field (see, for example, Weinreich, 1953). Recent studies in bilingual first language acquisition (BFLA) demonstrate that, at least in simultaneous bilingual acquisition, i...
