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…

While there is a growing body of research on second language acquisition (SLA) in children, adolescents, young and more mature adults, much remains to be explored about how adults in later life learn a new language and how good additional language learning is for them. Our goal in this article is to survey and evaluate what is known about the…

This article introduces this special issue by declaring that the studies contained here build on the idea that multilinguals, in the sense of learners or speakers that have more than two languages in their linguistic repertoire, are different from bilinguals and monolinguals in various ways. Several authors in the area of third language…

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…

Strikingly apparent within the demographics of New England, Portuguese is a language rich in standard and nonstandard varieties.

This issue has received considerable attention in second language (L2) research. The present study discusses the…

This study engages with a participatory oral history project that explores 3 themes.

Learning a foreign language implies that the learner will become, after a number of years, proficient at expressing ideas, dominating new sounds (phonology), improving the range of words (lexicon), becoming proficient at expressing thoughts in acceptable grammatical form (syntax), and gain sufficient mastery to communicate with negative speakers.…

Language learning has been increasingly influenced by technology over the last decades thanks to its positive effects on language acquisition. It is thanks to the technology's supportive role towards language learning that an increasing number of online foreign language courses have appeared. Besides, foreign language courses are more and more…

It remains unclear whether adult-learned second language (L2) depends on similar or different neurocognitive mechanisms as those involved in first language (L1). We examined whether English past tense forms are computed similarly or differently by L1 and L2 English speakers, and what factors might affect this: regularity (regular vs. irregular…
