Cognitive flexibility (switching) and control (inhibition) are among widely accepted cognitive advantages of bilingualism. Switch Cost (SC), i.e., the time difference to complete a switch versus non-switch task, is a construct for measuring the switching ability. The need to control the interference and switching between one's languages leads to…

The unforeseen shift to virtual learning during the COVID-19 pandemic required instructors and students to face unprecedented learning challenges. Under these circumstances, Chinese international students who intended to come to the U.S. to begin their studies were required to remotely access their courses while still residing in China, which…

We investigated age-related decline in adult learning of Dutch as an additional language (Ln) in speaking, writing, listening, and reading proficiency test scores for 56,024 adult immigrants with 50 L1s who came to the Netherlands for study or work. Performance for all four language skills turned out to decline monotonically after an age of…

Bilingual children with a limited command of the second language (L2) often yield unsatisfactory results in L2-based non-word repetition tasks (NWRT) for the assessment of working memory. In this study, monolinguals (MO) and bilinguals (BI) of preschool age acquiring German were compared in regard to their performance on German-based NWRT to…

This study builds on prior research on second language (L2) Spanish psych verbs, which has centered on morphosyntactic properties, by examining their syntactic distribution, which relies on lexical semantic knowledge. The fact that certain forms are licensed for some verbs, but not others, is the result of an underlying lexical semantic difference…

This study investigates the acquisition of null subjects by Mandarin Chinese native speakers ('Chinese NSs' hereafter), with different levels of L2 English proficiency, at initial stages of L3 Italian acquisition. The aim is to find out if, when acquiring Italian null subjects, Chinese NSs resort to their L1, which, like the L3, allows null…

Previous studies on lexical focus on form (FonF) have mostly centred on FonF in reading with a few pre-selected lexical items. This study investigated the contribution of oral incidental FonF to developing learners' lexical knowledge in a free discussion EFL class. Incidental FonF was provided to 15 upper-intermediate learners who participated in…

The proficiency in vernacular has long been a methodological ethos pervasive among field researchers and--despite new dynamics of fieldwork--still overshadows discussions related to collaboration with translators and interpreters, which are either marginalized or hidden within the category of a 'research assistant'. The purpose of this study is to…

The present project is a research-based and practice-tested online synchronous curriculum for English language learners with the Russian language mother tongue. The curriculum's theoretical component is grounded in Vygotsky's, Leont'ev', and Engestrom's "Cultural Historical Activity Theory" as well as in scholarly papers on the influence…

Child peer interaction in English as a foreign language (EFL) settings has recently received increasing attention with respect to age, instruction type and first language (L1) use, but longitudinal studies remain scarce and the effects of proficiency pairing and language choice on meaning negotiation strategies are still rather unexplored. Within…

Success in higher education is highly dependent on students' ability to efficiently read and comprehend large amounts of text in the speaker's first/native language (L1) and also in a Foreign Language (FL). Good text comprehension requires readers to implement a variety of metacognitive processes in order to self-regulate understanding. However,…

Taking into account the implicit/explicit knowledge of Tense Consistency (TC), this study aimed to investigate TC observance across Iranian EFL learners' proficiency specifically at elementary, intermediate and advanced levels. To achieve this, the Oxford Placement Test, Gap Filling Task and Spoken Performance Task were administered to 154…

While an elicited imitation test (EIT) has been widely used as a measure of oral proficiency in second language acquisition (SLA) research, it is still unclear the extent to which memory capacity impacts EIT performance. In light of this gap, the present study sought to clarify the nature of elicited imitation by examining the relative…

It is well known that article usage is difficult for learners of English to acquire. Indeed, learner errors such as "*many of people" are not uncommon. A closer look at similar multiword sequences reveals why learners might have difficulty using articles properly in such expressions: No definite article is required in phrases like…

The coronavirus pandemic that swept into communities across the United States beginning in Spring 2020 has placed enormous strain on health-care systems and highlighted the work of both U.S.- and foreign-born health professionals. But even as the need for testing, treatment, and care is high, an estimated 263,000 immigrants and refugees with at…
