Language proficiency is multi-componential in nature and, according to many SLA researchers and L2 practitioners, is best captured by the concepts of complexity, accuracy, and fluency (CAF). Two of the three studies reported in this paper adopted the Cognition Hypothesis (Robinson, 2003) as the means to address the question of whether increasing…

The current project longitudinally investigated the extent to which first-year Japanese university students developed their second language (L2) oral ability in relation to increased input in foreign language classrooms. Their spontaneous speech was elicited at the beginning, middle and end of one academic year, and then judged by linguistically…

The study reported in this article investigated the proficiency in French of a group of anglophone adult L2 learners of the language, all of whom reported passing regularly for native speakers of French. Tests were administered to these learners to gauge their proficiency in different aspects of French, including a lexico-grammatical measure. A…

While research suggests that study abroad (SA) benefits second language (L2) oral fluency, its benefits for other domains are less clear, especially for shorterterm programs, which are becoming more common. Additionally, studies investigating the relationship between cognitive capacity and benefits of SA report inconsistent patterns. In light of…

For all families with deaf children, choosing communication methods is a complex and evolving business. This process is particularly complex for migrant background families, who must not only negotiate the role that speaking or signing will play in their communication practices, but also which spoken language(s) will be used--that of the host…

Purpose: The present study was designed to investigate what linguistic variables best predict bilingual recognition of acoustically degraded sentences and how to identify bilingual individuals who might have more difficulty than their monolingual counterparts on such tasks. Method: Four hundred English speech-perception-in-noise (SPIN) sentences…

Research into complexity, accuracy and fluency (CAF) as basic dimensions of second language performance, proficiency and development has received increased attention in SLA. However, the larger picture in this field of research is often obscured by the breadth of scope, multiple objectives and lack of clarity as to how complexity, accuracy and…

We use a time-course analysis to examine the roles of vocabulary size and executive control in bilinguals' verbal fluency performance. Two groups of bilinguals and a group of monolingual adults were tested in English with verbal fluency subtests from the Delis-Kaplan Executive Function System. The two bilingual groups were equivalent in their…

There is a growing awareness of the importance of academic vocabulary, and more generally, of academic language proficiency, for students' success in school. There is also a growing body of research on the nature of the demands that academic language places on readers and writers, and on interventions to help students meet these demands. In this…

The human brain has the fascinating ability to represent and to process several languages. Although the first and further languages activate partially different brain networks, the linguistic factors underlying these differences in language processing have to be further specified. We investigated the neural correlates of language proficiency in a…

Extant research has primarily assessed the quality of the American school experience for immigrant students by focusing on performance-based outcomes (e.g., grade point average [GPA]). Unlike such research, the current study examines the impact of generational status and language proficiency on Latino and Asian students' (n = 2,261) attitudes…
