Research indicates that high-immersion virtual reality (VR) has several unique affordances for language learning that contribute to learning outcomes, such as boosting learners' confidence, engagement, and motivation. However, little is known about the extent to which VR promotes language skills, in particular learners' verbal interaction using a…

Drawing on positioning theory and Vygotsky's sociocultural theory of mind, this study analyzes the discursive processes through which expert and novice positions are negotiated in heritage-second language (HL-L2) learner interaction. It examines how positioning practices shape collaboration between HL and L2 learners, determining what types of…

As emotions research in the field of second language acquisition continues to evolve, it is equally important to explore the impact of social--emotional variables that are specifically relevant to heritage language (HL) contexts. Anchoring on foundations in critical heritage language education (HLE), this study examines the discomforts of the HL…

In this article, we present our vision of a transformed second language acquisition and teaching (SLA/T) disciplinary community that approaches second language (L2) education through four pillars. The first pillar is praxeology (i.e., the study of human action) to highlight the sociocontextually emergent nature of L2 competence. It locates the…

Evidence suggests that short-term study abroad experiences can help advance various dimensions of second language (L2) learners' linguistic competence. However, the extent to which gains following a brief sojourn are durable and maintained after immersion remains an open question. The present study examined both the immediate and sustained…

Although current approaches to second language (L2) pronunciation underscore that instruction should concentrate on pronunciation features that help learners be more intelligible (and not necessarily more native like), there is little empirical evidence as to what those features are, especially in languages other than English. To address this gap,…

This article examines language classrooms as communicative settings for learners' development of sociolinguistic competence involving target language variation in a study abroad context. Specifically, it investigates how two Spanish teachers in Peru imparted knowledge of the social and contextual appropriateness of local linguistic variants that…

The question of cognition in second language (L2) acquisition later in life is of importance inasmuch as L2 learning is largely mediated by domain-general cognitive capacities. While a number of these capacities have been shown to decline with age, individual differences in cognition increase over the lifespan. This microdevelopment study…

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…

This study uses a Q methodology to track the changing motivational profiles of 15 Chinese university students simultaneously engaged in second-language (L2) English and third-language (L3) Spanish learning over 1.5 years. Guided by complex dynamic systems theory (CDST), the study aims to investigate the initial trigger that propelled the Chinese…

Study abroad (SA) is touted for providing language learners with regular exposure to a second language (L2) in naturalistic settings. However, few studies have examined how interaction occurs in situ. This study analyzed 13 hours of naturalistic dyadic conversations self-recorded by 15 US-based undergraduate sojourners studying abroad for one…

In classrooms, teachers play a fundamental role in managing students' participation. As part of their classroom interactional competence to maximize interactional space for students' learning, teachers use multimodal resources to orchestrate turn-taking, allocate the next speaker, and manage repair sequences. However, little is known about how…

This study examined the relationship between lexical coverage (i.e., the percentage of known word tokens in a text) and second language (L2) reading comprehension. Several studies have suggested that adequate comprehension occurs between 95% and 98% coverage, but no study has investigated beginning-level learners reading under the conditions of…

Although most children learn to communicate in their first language (L1), there is normal and expected variation in their rate of acquisition across all components of the language system. Until recently, most second language acquisition and second language (L2) researchers have assumed that individual differences (IDs) in L1 acquisition are small…

This study explored the influence of speech rate (normal vs. fast), sentence length (short vs. long), and second language (L2) oral proficiency on listening comprehension in L2 Spanish. Thirty-one native English-speaking learners enrolled in upper-level Spanish courses were aurally exposed to 8 sentences of each type of speed--length matrix, for a…
