This paper seeks to present the case of successful nativelike proficiency in L7, achieved in adulthood. As a case study of multiple language acquisition processes acquired, both in childhood and adulthood, this study operates in the fields of multilingualism and language acquisition. The author presents her experiences of language acquisition and…

This dissertation is a quantitative analysis of language proficiencies through the lens of the dynamic model of multilingualism, using survival analysis to evaluate time until thresholds of foreign language proficiency are reached and nonparametric tests (Wilcoxon signed rank and Kruskal-Wallis) to compare proficiencies at distinct time intervals…

This study aimed to identify associations and predictors of willingness to communicate (WTC) of adult foreign language (FL) learners and whether they are contingent upon the FL being learned. To this end, our research investigated learner variables associated with WTC in adult FL learners of English and of French in an under-researched field of…

Upon arrival in Sweden, adult migrants are required to learn Swedish at the earliest opportunity. This requirement also extends to deaf migrants, regardless of their linguistic and educational backgrounds. This paper presents findings and experiences derived from a project focused on the multilingual situation of deaf migrants in Sweden. Some deaf…

In the vast literature on language attrition, studies on the role of extralinguistic factors in language retention, particularly concerning foreign language (FL) skills acquired in formal instructional contexts, are scarce. We address this issue by focusing on the impact of the frequency of FL use, both extramural and in the classroom, and…

Language-specific (i.e. the ideal L2 self) and plurilingual selves are now at the forefront of scholarly inquiry in L2 motivation research. Yet, there is a lack of empirical studies examining how language learners reframe their sense of self as speakers of an L2. This study draws on a questionnaire (N = 162) and on semi-structured interviews (N =…

In recent years, Third Language Acquisition (TLA) in Cross-Linguistic Influence (CLI) research has been debated regarding background languages' impact on learning a target language. While Second Language Acquisition (SLA) research often emphasizes the primary influence of the first language (L1) on the target language, it does not discount the…

For me, 'language learner autonomy' denotes a teaching/learning dynamic in which learners plan, implement, monitor and evaluate their own learning. From the beginning they do this as far as possible in the target language, which thus becomes a channel of their individual and collaborative agency. By exercising agency in the target language they…

This dissertation explores first language (L1) transfer and second language (L2) transfer processes and models, such as the full transfer/full access model (FT/FA), the representational deficit/interpretability hypothesis, and the feature reassembly hypothesis (FRH). The typological proximity model (TPM), the cumulative enhancement model (CEM),…

Research on the relationship between students' language learning motivation (LLM), language learning strategies (LLS), self-efficacy beliefs (SEB), and achievement in non-European languages has been both limited and overwhelmingly cross-sectional, often with little attention paid to their multilingualism. Combining complex dynamic systems and…

The Next Generation Science Standards (NGSS) provide a vision for contemporary science education with all students, including the fast-growing population of multilingual learners in the United States K-12 context. The shifts heralded by the NGSS have resulted in significant changes to English language proficiency (ELP) or English language…

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 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…

This study investigates the effects of multilingualism and the degree of proficiency in different languages on vocabulary knowledge among Spanish language learners. Participants completed a 160-word meaning recall test designed to measure their knowledge of the 8,000 most frequent Spanish words and a self-assessment questionnaire on their…

Due to the current status of English as a lingua franca in numerous domains, increasing attention has been directed toward the economic potential of English. However, research on languages other than English from an economic perspective remains limited. This study aims to address this gap by examining the labor market demand for Japanese language…
