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)…

Using the lenses of bilingualism and social justice, I reflect on relevant conceptual and methodological issues encountered in the study of the linguistic development of heritage language speakers. Themes examined include the early but varying timing of heritage language learning; the surrounding linguistic environment, including the link between…

This article proposes a formal model of the human language faculty that accommodates the possibility of 'attrition' (modification or loss) of morphosyntactic properties in a first language. Modeling L1 grammatical attrition entails a quite fundamental paradox: if the structure of the language faculty in principle allows for attrition of…

Much attention is now given to academic language, particularly in content areas such as science, amid persistent achievement disparities between students classified as English Language Learners, and more recently, Long Term English Learners, and their English-proficient peers. This attention has fueled debate about the precise features of such…

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…

Geography lessons center on a language-based product with socially relevant geographic content. The subject of geography in secondary schools in Germany faces three major challenges that make a stronger focus on language in the monolingual geography classroom necessary. First, more than 30 percent of German pupils in secondary schools have a…

Research using online comprehension measures with monolingual children shows that speed and accuracy of spoken word recognition are correlated with lexical development. Here we examined speech processing efficiency in relation to vocabulary development in bilingual children learning both Spanish and English (n=26 ; 2 ; 6). Between-language…

The fundamental difference hypothesis (FDH), as formulated by Bley-Vroman (1990), claims that SLA tends to be nonconvergent because domain-specific linguistic mechanisms available in early childhood cannot be used for language learning in adulthood: Instead, second language (L2) learners deploy domain-general problem solving skills. I claim that…

This study investigated the relationships between home language learning activities and vocabulary in a sample of monolingual native Dutch (n = 58) and bilingual immigrant Moroccan-Dutch (n = 46) and Turkish-Dutch (n = 55) 3-year-olds, speaking Tarifit-Berber, a nonscripted language, and Turkish as their first language (L1), respectively. Despite…

This paper presents the findings of an experiment in which 20 Greek Deaf students produced written texts under two different conditions of language input: (1) a translation from a videotaped story in Greek sign language, and (2) a direct composition produced from a picture story--a neutral non-linguistic input. Placing Deaf writing within a…

In this article we compare five groups of learners acquiring Dutch gender as marked on determiners and adjectival inflection. Groups of L1 (first language) children and L1-SLI (first-language specific-language-impairment) children are compared to three Turkish-Dutch L2 (second language) groups: adult L2, child L2 and child L2-SLI. Overall, our…

One of the issues that has been debated in the context of fairly open learning partnerships such as tandem learning has been whether and, if so, how much pedagogical support should be provided. Another issue is how do language learners who have grown accustomed to maximising their learning through comprehensible input and output make the…

This study compares the linguistic knowledge of adult second language (L2) learners, who learned the L2 after puberty, with the potentially "eroded" first language (L1) grammars of adult early bilinguals who were exposed to the target language since birth and learned the other language simultaneously, or early in childhood (before age 5). I make…

This paper considers the issue of non-target language representations analysing data from the acquisition of novel English synthetic compounds by bilingual (Basque-Spanish) speakers. Past research indicated that English L1 acquirers do not include regular -s inflection within compounds, whereas they do include irregulars (*"clawsmarks" versus…
