Discusses syntactic optionality, the coexistence within an individual grammar of two or more variants of a given construction that make use of the same lexical resources and express the same meaning. Focus is on syntactic optionality in second language grammars. (Author/VWL)

A comparison of the error profiles of monolingual (child L1) learners of Dutch, Moroccan children (child L2) and Moroccan adults (adult L2) learning Dutch as their L2 shows that participants in all groups massively overgeneralize [-neuter] articles to [+neuter] contexts. In all groups, the reverse gender mistake infrequently occurs. Gender…

Previous studies show that young monolingual children's ability to "fast map" new word forms is closely associated with both their age and existing vocabulary knowledge. In this study we investigate potential relationships between age, fast mapping skills and existing vocabulary knowledge in both languages of developing bilingual preschool…

Reviews two guides on the Child Language Data Exchange (CHILDES) project, both of which provide tools for analyzing talk. (Author/VWL)

Bilingualism is often considered an inappropriate developmental choice for children with specific language impairment (SLI) because, according to a widespread belief, these children's limited capacity for language would be overtaxed by learning two linguistic systems. However, there has not been adequate empirical investigation of SLI in bilingual…

Informal language learning is defined as learning assimilated without the pupil's awareness. (LG)

This paper reviews the biological origins of the critical period hypothesis and the neurophysiological evidence which was initially supplied in support of a critical period for the acquisition of language. Noting the inconclusive nature of neurophysiological evidence, the author suggests that we look to the interplay of affective and cognitive…

Presents an overview of the first quarter century of the Boston University Conference on Language Development (BUCLD), using data from interviews with people who have had various close connections to the conference throughout the years, including all of the principal faculty advisors, and 25 years of BUCLD handbooks, which are compiled annually.…

Examines the Child Language Data Exchange System (CHILDES), its organizational form, and its three major tools: (1) the CHILDES database of transcripts, (2) the CHAT system for transcribing and coding data, and (3) the CLAN programs for analyzing CHAT files. (GLR)

Examines whether bilingual children can differentiate their languages with respect to the ability to form compound nouns and to test the validity of previous explanations of the acquisition of compounds. Focused on whether a bilingual French-English child could differentiate between two compounding rules for nouns in the two languages. (Author/VWL)

This article reports on a study that addresses the following question: why do some children exposed to two languages from early on fail to speak those two languages? Questionnaire data were collected in 1,899 families in which at least one of the parents spoke a language other than the majority language. Each questionnaire asked about the home…

The data for this study consisted of a longitudinal corpus of narratives from 17 English second language (L2) children, mean age of 5;4 years at the outset, with first languages (Lls) that do not have definite/indefinite articles (Chinese, Korean and Japanese) and Lls that do have article systems (Spanish, Romanian and Arabic). We examined these…

Challenges the claim that adult second language acquisition is characteristically different, cognitively, from that of child first or second language acquisition. (PMP)

This article discusses the now established" fact that one aspect of language development in native English speakers is the increasing ability to embed larger and larger numbers of sentence consituents and considers its implications for second language acquisition. (FB)
