Globally classrooms are increasingly linguistically diverse. Research often oversimplifies lived linguistic heterogeneity as binary variables: native versus non-native. Linguistic distance (LD) measures allow a fine-grained operationalization of linguistic diversity in foreign language education. This study investigated associations of cognate LDs…

High-proficiency second language (L2) learners challenge much theory and methodology in contemporary sociolinguistic and L2 acquisition research, which suggests the need for honest interdisciplinarity when working in the interstices of style, stylization, and advanced acquisition processes. When to consider fluent and highly competent speakers of…

This study reports on the impact of 11 West European first languages on the acquisition of Dutch. Using data from nearly 6,000 second-language learners, it was found that the mother tongue had a rather large impact on two language skills--namely, oral and written proficiency--as measured by the scores received by these learners on the State…

Whereas most research in SLA assumes the relationship between the first language (L1) and the second language (L2) to be unidirectional, this study investigates the possibility of a bidirectional relationship. We examine the domain of manner of motion, in which monolingual Japanese and English speakers differ both in speech and gesture. Parallel…

Analysis of multilingual acquisition processes among children at the European School of Brussels reveals how both curricular and extra-curricular factors combine to account for these students' high levels of proficiency in three or four languages. Schumann's (1979) Acculturation Model applied to one case study allows examination of how the…
