Purpose: Individuals vary in their ability to learn the sound categories of nonnative languages (nonnative phonetic learning) and to adapt to systematic differences, such as accent or talker differences, in the sounds of their native language (native phonetic learning). Difficulties with both native and nonnative learning are well attested in…

The current study explores whether form-focused instruction with different timing and availability conditions can be used with repetitive writing tasks to enhance grammatical accuracy and fluency. Sixty-one intermediate English as a foreign language (EFL) learners performed three text reconstruction tasks: Task 1, Repeat Task, New Task, and…

This study uncovers the under-explored influences that encourage teachers to incorporate task-based language teaching (TBLT) for teaching Chinese as a second language, and the process of teachers' pedagogical attempts at a Chinese university. Activity Theory (Engeström, 1987) was adopted as the conceptual framework. As a qualitative study, the…

Many international students in American universities are required to take writing courses in English as a second language (ESL) before participating in a mainstream first-year composition (FYC) course. Given that the goal of ESL writing course is to prepare students for FYC course, the connection between ESL and FYC courses is significant. This…

Current second language (L2) listening research has lacked detailed accounts of L2 listeners' difficulties comprehending texts comprising orthographically known lexis. In the current study, 15 first language (L1) Japanese English language learners of three English proficiency levels listened to sentences and a narrative text. A two-task diagnostic…

The current study examined the effect of speaker variability on children's cross-situational word learning (XSWL). The study also examined the role of bilingual experience and sustained attention. Forty English monolingual children and 40 Spanish-English bilingual children ages 4-7 completed a XSWL task in a Single Speaker Condition and a Multiple…

The role of individual differences in second language (L2) learning is widely acknowledged; however, how teachers can accommodate individual differences in L2 classrooms receives relatively less attention. Focusing specifically on motivation, this study explores the effectiveness of communicative tasks on Korean L2 speakers' complexity, accuracy,…

This dissertation investigates how English-speaking second language (L2) learners of Mandarin perceive, process and learn Mandarin lexical tones. While most languages use modulations in pitch (intonation) to convey meanings at the phrasal and sentential levels, a number of languages, including Mandarin, also use suprasegmental features such as…

The present study examines the influence of social distance and power factors on the use of internal and external mitigating devices and strategies in the production of requests by Korean learners of Russian. The data was collected by using a Discourse Completion Task (DCT) containing twelve situations that varied in the facts of power and social…

This study evaluates attitudes toward nonnative Englishes among students, faculty, and staff at a STEM-focused U.S. university. The study utilizes the verbal-guise technique: Participants listened to and rated three summaries of the same short story as told by native speakers of U.S. English, Chinese, and Arabic. This adapted verbal-guise…

Background: Until today, there is no satisfying explanation for why one language may recover worse than another in differential bilingual aphasia. One potential explanation that has been largely unexplored is that differential aphasia is the consequence of a loss of language control rather than a loss of linguistic representations. Language…

A large dataset of word recognition behavior from nonnative speakers (NNS) of English was collected using an online crowdsourced lexical decision task. Lexical features were used to predict NNS lexical decision latencies and accuracies. Predictors of NNS latencies and accuracy included contextual diversity, age of acquisition, and contextual…

The current study investigated the mechanism of language switching in unbalanced visual unimodal bilinguals as well as balanced and unbalanced bimodal bilinguals during a picture naming task. All three groups exhibited significant switch costs across two languages, with symmetrical switch cost in balanced bimodal bilinguals and asymmetrical switch…

Previous research has suggested that Event-Related Potentials (ERPs) can index form-, meaning-, and use-related aspects of the second language (L2) vocabulary knowledge, through, respectively, a lexical decision task (LDT, targeting N400), a semantic relatedness task (SEMREL, targeting N400), and a grammatical judgment task (GJT, targeting…

The role of recasts, a corrective feedback technique, has received much attention from instructed SLA researchers. While a variety of factors have been identified as influencing their effectiveness in facilitating uptake and L2 development (e.g., learners' age and level of proficiency), the role of mode of interaction has been the object of…
