This special issue revisits a classic topic in linguistic theory, A-bar movement, applied to developing and bilingual grammars. We claim that A-bar movement, or filler-gap dependencies, is still the quintessential linguistic phenomenon to illustrate the interaction between the biological endowment, the experience with language (past and present),…

Whereas a growing amount of attention has been directed to the role of perceptual-cognitive aptitude in successful second language (L2) lexicogrammar learning, scholars have begun to investigate the same topic in the context of L2 pronunciation learning. To date, there is ongoing discussion on the mechanism underlying L2 speech learning in…

This study investigates sources of phonological cross-linguistic influence (CLI) at the initial stages of third language (L3) acquisition in light of the predictions of the second language (L2) Status Factor Model, the Typological Primacy Model, the Cumulative Enhancement Model, the Linguistic Proximity Model and the Scalpel Model. The productions…

Using self-paced reading, the present study compared native English and adult L1-Korean-L2-English speakers' processing behaviors during online comprehension of underinformative scalar sentences and non-scalar sentences like "Some/All elephants have trunks and ears." Results indicate that native speakers showed online sensitivity (i.e.…

Norwegian allows filler-gap dependencies into embedded questions, which are islands for filler-gap dependency formation in English. We ask whether there is evidence that Norwegian learners of English transfer the functional structure that permits island violations from their first language (L1) to their second language (L2). In two acceptability…

As research into online informal language learning (OILL) develops as a field, the impact on such practices for a wide variety of contexts can be considered. In the case of this publication, the study abroad (SA) context is of particular interest. Indeed the study abroad student may interact with a range of online learning resources in formal,…

The current study longitudinally examined a crucial individual difference variable -- i.e. awareness (operationalized as explicit attention and articulatory knowledge) -- in adult second language (L2) speech learning in the context of 40 Japanese learners' English /[alveolar approximant]/ pronunciation development in an EFL classroom. The…

Frequent language exposure and use are among the most important conditions for successful language learning, whether in classrooms, during study abroad, or in other informal contexts. Research probing exposure and usage often relies on one-off self-report questionnaires in which participants estimate their typical level of language exposure over…

In order to understand variability in second language (L2) acquisition, this study addressed how individual differences in cognitive abilities may contribute to development for learners in different contexts. Specifically, we report the results of two short-term longitudinal studies aimed at examining the role of cognitive abilities in accounting…

Adults demonstrate difficulty and pronounced variability when developing second language (L2) grammatical knowledge and reading skills. We examine explanations in terms of individual differences in working memory (WM). Despite numerous studies, the association between WM and adult second language (L2) acquisition remains unclear, and longitudinal…

Most linguistic processes--acquisition, change, deterioration--take place in and are determined by a complex and multifactorial web of language internal and language external influences. This implies that the impact of each individual factor can only be determined on the basis of a careful consideration of its interplay with all other factors. The…

Examines the possible and specific relationships between first language (L1) acquisition and second language (L2) acquisition to show that a number of assumptions warrant closer inspection. Explores problems in distinguishing L1 from L2 acquisition from three different perspectives: individual language learner histories, the data, and the…

Discusses the feasibility of Basic Variety (BV) principles proposed by Klein and Perdue, arguing that some of them need clarification with learner varieties and that they are not part of Universal Grammar (UG) as they exclude phenomena (e.g., psych verbs) that cannot be excluded from the core of natural language.

Ways in which studies in second-language acquisition research can illuminate first-language acquisition research are explored. Emphasis is on issues of learner strategies, individual variation, acquisition of late learned structures, bilingualism, Universal Grammar, and the fate of obsolete knowledge in acquisition.

Examines evidence offered to support the idea of a sensitive period for second language acquisition. Findings indicate that there is insufficient evidence to accept the claim that mastery of a second language is determined wholly, or even primarily, by maturational factors.
