While semantic and syntactic properties of verb meaning can impact the success of verb learning at a single age, developmental changes in how these factors influence acquisition are largely unexplored. We ask whether the impact of syntactic and semantic properties on verb vocabulary development varies with age and language ability for toddlers…

Aptitude is a hypernym used in training and practice-based contexts to refer to a person's natural or acquired ability to do something. It tends to be an attribute that is 'forward-looking', i.e. referring to a person's probability of achieving success in the future. This paper adopts a retrospective perspective in looking at the 'success…

We investigated the potential influence of implicit learning mechanisms on L2 morphosyntactic attainment by examining the relationship between age of onset (AoO), two cognitive abilities hypothesized to underlie implicit learning (phonological short-term memory and implicit statistical learning), and performance on an auditory grammaticality…

This study compares the performance of native speakers and adult second language (L2) learners on tasks tapping proficiency in grammar, vocabulary, and collocations. In addition, data were collected on several predictors of individual differences in linguistic attainment, including some related to language experience (print exposure, education,…

This study investigated the effects of task complexity on child learners' second language (L2) gains, the relationship between aptitude and L2 development, and the extent to which task complexity influences this relationship when recasts are provided. Sixty child EFL learners were assigned to two experimental groups. During the treatment, one…

Pragmatic differentiation in bilinguals is the ability to use two languages appropriately with different speakers. Although some sensitivity emerges by 2 years, the effects of context on these skills and their relation to other developing metacognitive capacities have not been examined. The current study compared the language use of 28 bilingual…

Although the majority of New Zealanders speak English, and only English, the 1987 Maori Language Act and immigration from both Asia and the Pacific have had a significant impact on New Zealand society. Because increasing numbers of children are entering school with limited English language ability, students are arguably the group with the most…

Drawing on recent psychological and neurological research on how individual differences might interact with learning a particular language, the study examines how psycholinguistic research and theory can help in assigning military personnel to language training and to a given language. Using the Defense Language Institute's Defense Language…
