Short term memory (STM) and working memory (WM) performance consistently predict language abilities in children with developmental language disorders. However, causality is not fully established. Moreover, evidence from the fine-grained analysis of STM/WM tasks and comprehension of complex sentences, suggests that long term memory (LTM)…

The central claim in Amaral and Roeper's (this issue; henceforth A&R) keynote article is that everyone is multilingual, whether they speak one or more languages. In a nutshell, the idea is that each speaker has multiple grammars or "sub-sets of rules (or sub-grammars) that co-exist". Thus, rather than positing complex rules to…

Jurgen Meisel argues that "grammatical variation...can be described...in terms of parametric variation", and--crucially for his arguments in this paper--that "parameter settings do not change across the lifespan". To this extent he adopts the standard generative view, but he then departs from what he calls "the literature on historical…

Lidz et al. [Lidz, J., Waxman, S., & Freedman, J. (2003). What infants know about syntax but couldn't have learned: Experimental evidence for syntactic structure at 18 months. Cognition, 89, B65-B73.] claim experimental substantiation of an argument from the poverty of the stimulus, in the sense of Pullum and Scholz [Linguist. Rev. 19 (2002) 9].…

From perspective of a psycholinguist, discusses three leading questions that have arisen from foundational, descriptive second-language-acquisiton studies: Why are certain L2 constructions learnable and others not?; In considering input requirements, is it fair to say that adult learners can take advantage of metalinguistic information about the…

Reviews research findings on second-language (L2) interaction from the perspective of syntactic development. The article argues that better understanding of the role of negotiated interaction in L2 syntactic development requires examining the specific grammatical structures in interaction guided by the criteria of relevance, availability,…
