We investigated how naturalistic actions in a highly immersive, multimodal, interactive 3D virtual reality (VR) environment may enhance word encoding by recording EEG in a pre/post-test learning paradigm. While behavior data have shown that coupling word encoding with gestures congruent with word meaning enhances learning, the neural underpinnings of this effect have yet to be elucidated. We coupled EEG recording with VR to examine whether embodied learning improves learning and creates linguistic representations that produce greater motor resonance. Participants learned action verbs in an L2 in two different conditions: specific action (observing and performing congruent actions on virtual objects) and pointing (observing actions and pointing to virtual objects). Pre- and post-training participants performed a match-mismatch task as we measured EEG (variation in the N400 response as a function of match between observed actions and auditory verbs) and a passive listening task while we measured motor activation (mu [8-13 Hz] and beta band [13-30 Hz] desynchronization during auditory verb processing) during verb processing. Contrary to our expectations, post-training results revealed neither semantic nor motor effects in either group when considered independently of learning success. Behavioral results showed a great deal of variability in learning success. When considering performance, low performance learners showed no semantic effect and high performance learners exhibited an N400 effect for mismatch versus match trials post-training, independent of the type of learning. Taken as a whole, our results suggest that embodied processes can play an important role in L2 learning.

Bilingualism and multilingualism provide a unique lens for exploring how human experiences influence language and cognition. This editorial presents a collection of studies on the relationship between bilingualism/multilingualism and cognition in typically developing and neurodiverse populations. The articles assembled in this issue synthesize findings from diverse linguistic populations (e.g., second-language learners, heritage speakers, different-script bilinguals, etc.) and techniques (e.g., behavioral, magnetic resonance imaging, electroencephalography, eye-tracking, etc.) to provide compelling evidence that knowing more than one language can benefit learning, health, and social outcomes. Translational research on bilingualism and multilingualism is necessary for informing policy and can serve as a guide to researchers, practitioners, and educators who work with linguistically diverse populations, as well as individuals and parents who speak multiple languages. We conclude that multilingualism shapes cells, selves, and societies.

The paper introduces the Special Issue on Language Contact and Speaker Accommodation, which originates from the conference Phonetics and Phonology in Europe (PaPE) held at the University of Lecce, Italy, in 2019. It discusses the topics of language contact and speaker accommodation, summarizing the contributions included in the Special Issue, and arguing explicitly in favour of a unitary view of how both temporary and stable changes happen in (part of) the linguistic systems. Accommodation is seen as the same gradual and non-homogeneous process at play in different contact settings. In the introductory sections, a discussion is offered on various situations in which linguistic systems are in contact and on the main factors that may be at play; the following sections offer an overview of the papers included in the Special Issue, which focus on accommodation in L2 and heritage speakers as well as on the time dimension of dialect or language societal contact. Finally, accommodation is discussed as the same process that is at work in any interaction, that may modify temporarily or long-term the system of L2 learners and bilinguals (e.g., immigrants), that usually affects in the long-term the heritage speakers\' system, and that only in the long term can lead to language changes involving entire communities.

Despite the significance of grit and motivational regulation strategies (MRS) to language learning, limited research has been conducted on their longitudinal interplay. The present study explores the relationship between these two constructs in an English as a second language (L2) learning context through a longitudinal design. This study utilizes repeated measures of L2 grit and MRS at two time points (T1 and T2) to investigate the direction of influence between them and proposes and evaluates four models: an autoregressive model, two unidirectional models, and a bidirectional model. Using questionnaire data from 205 Chinese university students to evaluate the models, results from model assessment revealed that L2 grit at T1 positively predicted L2 grit at T2 and that MRS at T1 positively predicted MRS at T2. While L2 grit showed stability, MRS developed over time. The unidirectional model with L2 grit at T1 as a predictor of MRS at T2 was identified as the model of best fit, indicating that L2 grit at an earlier time unidirectionally influenced MRS at a later time. Based on these findings, we conclude that there is a unidirectional influence between L2 grit and MRS: the former plays an influential role in shaping MRS in L2 learning over time. Implications and recommendations for future research are discussed. This study contributes to a deeper understanding of the dynamics between the two constructs, which in turn impacts language learning persistence and success, offering valuable insights for educators, policymakers, and researchers striving to optimize language learning environments and interventions.

As corrective feedback (CF) is conducive to students\' second language (L2) development, a considerable number of studies have investigated the effects of different types of CF strategies on EFL/ESL learning achievement. However, the role of learner engagement has been largely neglected in the field of CF research. The present study aims to describe the role of learner engagement with CF in EFL/ESL classrooms by reviewing theoretical and empirical evidence. The findings reveal that learner engagement is indispensable for CF to be effective, and providing strategies for working with CF is essential to guide EFL/ESL learners in their learning process. The implications for teacher CF practice and learner engagement training are also discussed.

The process of learning a new language can be filled with many emotions, both positive and negative, for the learner. This is particularly true in the area of writing, where students may feel a close connection to their sense of self. Thus far, the foreign language teaching profession has tended to prioritize cognition over emotion in research and classroom practice, with limited attention paid to the role of emotions in language learning. Recently, however, scholars, influenced by psychology, have taken a more active look at how emotions might mediate language learning. Among these scholars, Rebecca Oxford proposed a model that integrates tenets of positive psychology and second language learning, which she has designated as EMPATHICS. This nine-component model examines emotions/empathy, meaning/motivation, perseverance, agency/autonomy, time, hardiness/habits of mind, intelligences, characteristics, and self-factors. In this paper, we apply the EMPATHICS model to teaching second language writing and offer suggestions for task design at different stages of the writing process. While many second language teachers already incorporate some aspects of positive psychology in their classroom, becoming explicitly aware of its potential to foster better learning outcomes behooves us all.

This experiment was designed to investigate conceptual links directly through a word-picture matching task in children. Participants were asked to indicate between two pictures the one depicting the same concept as the newly learned L2 word (target). One of the two pictures was the target, while the other was either semantically related to it or was unrelated. To investigate whether learning methods modulate L2 word processing, two learning methods were compared: an L2-photograph method and an L1-L2 method. Results showed a semantic interference effect only with the L2-photograph method: Children responded more slowly in the related condition than in the unrelated one. The learning method modulated L2 word processing and L2 word meaning was not necessarily accessed through L1 mediation in the first steps of learning. The method used paves the way for the direct investigation of conceptual links.

One of the prominent ideas developed by Jacques Mehler and his colleagues was that perceptual tuning, present from birth on, enables infants, and language learners in general, to extract regularities from speech input. Here we discuss language learners\'\' ability to extract basic word order (VO or OV) structure from prosodic regularities in a language. The two are closely related: in phonological phrases of VO languages, the most prominent word is the rightmost one, and in OV languages, it is the leftmost one. In speech, this prominence is realized as extended duration, or as elevated pitch, sometimes combined with changes in intensity. When learning the first (L1) or the second language (L2), exposure to relevant rhythmic structure elicits implicit learning about syntactic structure, including the basic word order. However, it remains unclear whether triggering the learning process requires a certain level of familiarity with the relevant rhythm. It is moreover unknown whether prosodic information can help L2 learners to extract and learn the vocabulary of a new language. We tested Spanish- and Italian-speaking adults\' ability to learn words from an artificial language with either non-native OV or native VO word order. The results show that learners used prosodic information to identify the most prominent words in short utterances when the artificial language was similar to the native language, with duration-based prominence in prosody and a VO word order. In contrast, when the artificial language had a non-native prominence marked by pitch alternations and an OV word order, prominent words were learned only after a three-day exposure to the relevant rhythmic structure. Thus, for adult L2 learners, only repeated exposure to the relevant prosody elicited learning new words from an unknown language with non-native prosodic marking, indicating that, with familiarity, prosodic cues can facilitate learning in L2.

The aim of the study was to investigate both L2 word integration and the effect of learning method on it. For this purpose, an L2 word-learning paradigm was designed with two learning methods: L2 words were paired with videos in the first one and their translation-equivalent L1 words in the second. To test L2 word integration, a lexical decision task associated with form priming was administered before and after the learning phase. The L2 words to be learned were used as primes. Forty-eight participants participated in the study. Before learning, a facilitation effect was obtained with pseudowords (not already learned L2 words) as primes and L1 words as targets. After learning, L2 words no longer facilitated L1 word recognition when learned with the video method, while they still had this effect when learned with the L1 words - L2 words method. In accordance with the prime lexicality effect (PLE), this absence of a facilitation effect indicates that L1 words and L2 words are involved in a lexical competition process common to the two languages. This result highlights swift lexicalisation and demonstrates the effect of learning method in lexicalisation.

BACKGROUND: Mastering the phonetics of a second language (L2) involves a component of speech-motor skill, and it has been suggested that L2 learners aiming to achieve a more native-like pronunciation could benefit from practice structured in accordance with the principles of motor learning.
METHODS: This study investigated the influence one such principle, high versus low variability in practice, has on speech-motor learning for Korean adults seeking to acquire native-like production of English rhotics. Practice incorporated a commercially available intraoral placement device (\"R Buddy,\" Speech Buddies Inc.). In a single-subject across-behaviors design, 8 participants were pseudorandomly assigned to practice rhotic targets in a low-variability (single word) or high-variability (multiple words) practice condition.
RESULTS: The hypothesized advantage for high-variability over low-variability practice was observed in the short-term time frame. However, long-term learning was limited in nature for both conditions.
CONCLUSIONS: These results suggest that future research should incorporate high-variability practice while identifying additional manipulations to maximize the magnitude of long-term generalization learning.
