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…

The present study explores the impact of different levels of competition involved in gamified learning on adult e-learners' intrinsic motivation, learning engagement, and language learning performance. One hundred and twenty participants were evenly and randomly assigned to two groups. A gamified learning procedure with a higher level of…

The United States government is perennially in need of employees with proficiency in critical foreign languages to communicate with foreign counterparts and maintain relationships worldwide. In order to fulfill this need, the government devotes significant resources training federal employees to advanced levels of language proficiency through…

With the advancement of educational technologies, computer-assisted language learning (CALL) tools, like online dictionaries, are essential for acquiring a second language, especially new vocabulary. There has been no empirical focus on the usage of "Gabra" online dictionary in learning Maltese, with a specific focus on international…

This case study aims to explore English language vocabulary acquisition experiences and conceptualizations of a single adult English language learner with mild dyslexia by drawing on metaphors and semi-structured interviews. In the study, we aimed to view the learner's perception through different lenses to gain deeper insight into her ulterior…

We inquired whether introducing variability into a word-learning task would facilitate, inhibit, or have a neutral effect on adults' speech production and language learning. Twenty young adults from the U.S. Midwest with typical development participated. They repeated four novel words 10 times sequentially (blocked practice) and another four novel…

The creative and dynamic practices that multilinguals perform with linguistic and non-linguistic features such as the body, movement, senses, and space have been documented as integral to their repertoire. Drawing on interdisciplinary literature, this article advances the concept of the repertoire through "translanguaging drama" as a…

Research shows that educators' perceptions of learning are limited due to a variety of factors which include: a lack of neurobiological- and language acquisition-informed content and information incorporated within teacher preparation programs, educators' learning experiences grounded in familiarity, and confusions between common educational…

Phonotactic patterns are generalizations that govern the order of consonants and vowels, within words and syllables. Certain second-order phonotactic patterns--those that relate multiple sounds within a syllable, such as "if the vowel is [near-close near-front unrounded vowel], then [s] can only appear at the end of the…

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. In studying Portuguese, it is common for some students to acquire language more easily than their peers, despite receiving the same linguistic input, and others display negative attitudes toward their instructor's…

When an adult migrant begins to acquire a second language, it is often presumed that the learner is already equipped with first language literacy and can therefore transfer these same literacy skills during their acquisition of the new, second language. However, many adult second language (L2) learners lack the opportunity to develop first…

Phonotactics--constraints on the position and combination of speech sounds within syllables--are subject to statistical differences that gradiently affect speaker and listener behavior (e.g., Vitevitch & Luce, 1999). What statistical properties drive the acquisition of such constraints? Because they are naturally highly correlated, previous…
