This book traces and summarizes theoretical insights and empirical findings on the topic of whether or not anxiety for language learning could be a causal variable for individual differences in language learning. The author brings together three decades of research to show that first language (L1) skills and second language (L2) aptitude are…

This study identified changes in Korean and heritage language proficiencies across five waves (2011-2015) and examined the association between linguistic acculturation trajectories and adjustment (2016) among Korean adolescents with immigrant family backgrounds (N = 1441; 51.21% female; M[subscript age(baseline)] = 9.97). All adolescents were from…

Our preferences and evaluations are often affected by contextual factors. One unavoidable context is language. We used an evaluative conditioning (EC) paradigm (pairing neutral stimuli with emotional or neutral stimuli) to investigate whether our evaluations are equally conditioned in a first (L1) and a second language (L2). An EC effect was…

In L1 attrition research, it's recognized that a previously acquired language can transform under the influence of a newly acquired one. However, the precise L1-L2 relationship is intricate and warrants further study. Some research suggest that L2 mastery might reduce L1 proficiency, while others show that both languages can be maintained. Age of…

This study investigates the relationship between acculturation and language attitudes among Turkish immigrant parents and their children's heritage language proficiency, using Vygotsky's sociocultural theory (Vygotsky, 1978) and Berry's acculturation theory (Berry, 1997). Fifty-two Turkish parents (M age = 38.15, SD age = 4.84) completed…

Evaluating students from culturally and linguistically diverse backgrounds (i.e., emergent bilinguals) presents challenges to evaluation teams, as distinguishing between a language disorder and typical second language development is more complex. The skills and knowledge required to do this task often exceed the level of training that evaluators…

This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

Family language strategies are approaches that parents adopt for language use with their multilingual children. In bilingual contexts, these strategies influence children's language exposure and development (MacLeod et al., 2022). In the more complex context of trilingualism, how families settle on strategies and their relationship with exposure…

This dissertation examines the acquisitional process of middle se constructions by English- and Korean-speaking L2 learners of Spanish. Although clitic se is well known for its multifunctionality, there is a general tendency in the literature to analyze any use of "se" as a reflexive marker. This tendency is especially prominent in the…

Purpose: We examined native language (L1) and second language (L2) convergence of underlying skills in adult L2 learners as well as the contribution of instructional L2 level on L2 attainment across speech motor, lexical, and narrative levels. Method: Thirty-four adult Spanish L2 learners who had completed at least 1 year of college Spanish…

Given the importance of conversation practice in language learning, chatbots, especially ChatGPT, have attracted considerable attention for their ability to converse with learners using natural language. This review contributes to the literature by examining the currently unclear overall effect of using chatbots on language learning performance…

In this study, 96 world language teachers in the state of Georgia completed a survey regarding their delivery of instruction in the target language. While ACTFL (2010, 2021) recommends using the target language 90% or more of the time to deliver instruction, only 20% of the world language instructors who were surveyed reported doing so. According…

Bilingual students can take notes in their first language (L1) or their second language (L2). Higher note-taking quality, which might differ between the L1 and L2, has been associated with better memory of new content. In this study, we examined how language of note taking within bilinguals affects note quality and memory of new content. One…

This study aims to provide a comprehensive profile of collocational competence, a key component of one's overall linguistic competence. For the maximum of ecological validity, we elicited naturalistic oral/written production data from 84 Chinese intermediate EFL learners and performed a 2×2 fashion of analysis on their performance in each of the…

This paper provides fresh insights on how PIs (Polarity Items) in non-veridical contexts (questions and conditionals) are represented in the grammar of multilingual learners of Catalan at different stages of development. It explores how this non-native grammatical system interacts with other previously acquired systems of negation and the implicit…
