While language dominance has been crucial in the study of bilingualism, recent research has called for more detailed measures to systematically account for the observation that bilinguals use different languages in different domains, a phenomenon formalized in the Complementary Principle. Few studies have systematically measured these…

This paper proposes a concept of "campus vitality" of languages: the ability of a language to maintain its prestige, visibility and continuity on university campuses. A seven-factor framework is developed for on-the-ground investigation of the relevant languages in a given campus context. These indexical factors are the number,…

Teachers play an essential role in fostering linguistic security in their classrooms. The aim of this study is to identify the language ideologies articulated by teachers in the Francophone schools of the English-dominant context of British Columbia (Canada) in order to explore how the different practices they implement to foster the use of French…

This book gives an overview of the linguistic development of Korean-English bilingual children living in the US. It provides a detailed longitudinal account of English and Korean acquisition in early childhood, offering a close examination of Korean-American children's code-switching and morphology and syntax development during a time when their…

Literature on early language acquisition has observed that age of onset of acquisition (AoA) is relevant for certain grammatical phenomena. Simultaneous bilinguals receive regular and extensive exposure to two languages from birth (Müller, 2009), whereas sequential child learners get in extensive contact to L[subscript B] once the L[subscript A]…

This study investigated and compared family language policies (FLPs) from the perspectives of two groups of Singaporean bilingual children: 2,971 English-Chinese and 780 English-Malay children (aged 9-11 years). It also examined how different FLP components -- namely, language beliefs, practices, and management -- influenced their leisure reading…

A substantial body of research has examined the role of English in South Africans' linguistic repertoires. Many of these studies have investigated whether a language shift towards English might be underway among first-language (L1) speakers of the indigenous languages. At the same time, the role of English in the repertoires of L1 English speakers…

Verbal morphology has been identified as a particularly vulnerable domain for adult heritage speakers (HSs) of Spanish, especially when it involves the selection of subjunctive mood. A minimal amount is known, however, about the potential effects of the variability associated with these forms on the acquisition of related epiphenomena, such as the…

Measuring language dominance, broadly defined as the relative strength of each of a bilingual's two languages, remains a crucial methodological issue in bilingualism research. While various methods have been proposed, the Bilingual Language Profile (BLP) has been one of the most widely used tools for measuring language dominance. While previous…

For more than a decade, research on heritage speakers' (HSs') mood selection has documented a high degree of variability in their interpretation and use of mood morphology in variable contexts. Most of the previous literature, however, has focused on late-acquired alternations, and often limited analyses to one form (i.e., subjunctive), making it…

Bilingual children, the majority of whom are Spanish-English learners, now constitute over a third of the preschool population in the United States (Migration Policy Institute, 2021). Bilingual children and their families face multiple barriers to high-quality early childhood education, which are largely due to the underutilization of culturally…

This study discusses the impact of interactionist output-oriented approaches, specifically, the effects of collaborative text reconstruction on subjunctive recognition and production in the written modality by English-dominant Spanish second-language learners. It also examines whether students' text length and text complexity increase after…

Multilinguals' feelings of difference when switching languages have been discussed extensively. However, this research area has mainly focused on multilinguals dominant in their first language (L1), examining the feelings they experience when using any language other than the L1 (LX). The present study offers a novel perspective on this topic and…

An aim of research on bilingualism is to understand how the brain adapts to the use of more than one language. Although several important discoveries and insights about the consequences of bilingualism have been generated over the last several decades, concerns about replicability have narrowed the scope of inquiry and discussion to the…

This study explores English-dominant speakers' and English learners' knowledge of (in)formal stylistic variants, their choice of (in)formal styles in relation to social context, their preferences in the use of select (in)formal stylistic variants, and their beliefs about the influence of their other languages. Ten English-dominant undergraduates…
