The present study uses event-related potentials (ERPs) to examine nonlocal agreement processing between native (L1) English speakers and Chinese-English second language (L2) learners, whose L1 lacks number agreement. We manipulated number marking with determiners ("the" vs. "that"/"these") to see how…

This study addresses the role of domain-general mechanisms in second-language learning and knowledge using an individual differences approach. We examine the predictive validity of implicit-statistical learning aptitude for implicit second-language knowledge. Participants (n = 131) completed a battery of four aptitude measures and nine grammar…

The present study examined whether early immersive L2 exposure in a foreign language learning context can yield long-term advantages in L2 morpho-syntactic sensitivity. Participants were 40 Korean university students with high English proficiency, who had either attended an English kindergarten or begun learning English in a classroom, and a…

This study examined the linguistic dimensions of comprehensibility and perceived fluency in the context of L2 argumentative speech elicited from 40 Japanese-speaking learners of English. Their speaking performance was judged by 10 inexperienced native speakers of English for comprehensibility and perceived fluency, and was also objectively…

This study critically examined the previously reported partial independence between second language (L2) accentedness (degree to which L2 speech differs from the target variety) and comprehensibility (ease of understanding). In prior work, comprehensibility was linked to multiple linguistic dimensions of L2 speech (phonology, fuency, lexis,…

This study partially replicates McManus and Marsden (2017), who found that providing L1 explicit information (EI) plus task-essential practice led L2 learners to make more accurate and faster interpretations of French morphosyntax. The current study removed the original study's L1 EI component to examine the role of the L1 practice. This design…

Two eye-tracking experiments tested (a) whether L2 learners benefit from the consistency of input modality (auditory instead of written processing instruction [PI] training) and (b) whether they benefit from training using the same voice as the test voice. Results confirmed a robust effect of PI training on picture-selection accuracy, yet the…

This article synthesizes the conclusions of the empirical studies in this special issue and outlines key questions in future research. The research reported in this volume has identified several fundamental issues in pronunciation-focused task design that are discussed in detail and on which suggestions for further research are outlined. One…

We revisit morpheme studies to evaluate the long-standing claim for a universal order of acquisition. We investigate the L2 acquisition order of six English grammatical morphemes by learners from seven L1 groups across five proficiency levels. Data are drawn from approximately 10,000 written exam scripts from the Cambridge Learner Corpus. The…

This study examines the effects of the timing of explicit instruction (EI) on grammatical accuracy. A total of 123 learners were divided into two groups: those with some productive knowledge of past-counterfactual conditionals (+Prior Knowledge) and those without such knowledge (-Prior Knowledge). Each group was divided into four conditions. Two…
