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…

South Africa immediately springs to mind as the epitome of multilingual language policies. In fact, its Constitution granted official status to 11 languages in 1996, and the Language Policy in Higher Education passed by the Ministry of Education in 2002 required universities to develop and use the indigenous official languages as academic…

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…

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…

Linguistic research on bilinguals has sometimes focused on either first vs. second acquired language or dominant vs. non-dominant language despite situations in which the dominant and first language are no longer the same. Many bilinguals in the U.S. and other countries experience a change in language dominance from a home language to a majority…

This article investigates the language practices of a bilingual mariachi instructor teaching mariachi music to Latinx English dominant students. This ethnographic study draws on the concept of chronotope (Bakhtin 1981) to explore the spatiotemporal aspects of learning, particularly in terms of the teachers' selective use of language correction…

In this preregistered, longitudinal study of early code-switching, 34 US-born, Spanish-English bilingual children were recorded with a bilingual family member at 2;6 and 3;6, in Spanish-designated and English-designated interactions. Children's Spanish and English expressive vocabulary and their exposure to code-switching were measured through…

The present study draws on the theoretical framework of translanguaging and seeks to shed light on the patterns of translanguaging and how translanguaging affects meaning-making processes among bilingual children in preschool. This case study focuses on 8 months of observation and recordings of pupils ranging in age from 3 to 6 years. The gathered…

Despite the worldwide prevalence of multilingualism, the knowledge of the relationship between domain-general cognitive control and multilingual language control remains scant. Here we provide new insights into this issue by examining systematically how different components of inhibitory control (i.e., response inhibition and interference…

This study examines how dominance and proficiency relate to Spanish heritage speaker vowel productions. Participants' normalized vowel measurements were compared to nonheritage native speakers of Spanish and English using the Pillai score, an output of Multivariate Analysis of Variances (MANOVAs) that allows comparisons across distributions of two…

This ethnographic study utilized border theory to examine how a bilingual Latinx teacher created equitable instruction for Mexican immigrant second-graders in a 50-50 dual-language (DL) classroom in the U.S. Midwest. Approximately half the students in the DL classroom came from Spanish-speaking, working-class homes, and half from English-speaking,…

Although English-Chinese bilingual development has been studied in community contexts, it has not been adequately addressed in the K-12 Chinese immersion classrooms despite the increasing number of Chinese immersion programs across the United States. To inform effective pedagogies in Chinese immersion classrooms, this study reports on a nine-month…

This study documents the notion of unilateral translanguaging--the configuration of translanguaging spaces to disproportionately privilege a dominant language or its speakers. We analyze four teachers' translanguaging practices in a Portuguese-English two-way immersion (TWI) program in the United States. Rather than focusing on whether and how…

Purpose: This article aims to describe how exemplar variability can manipulate the word learning environment to maximize within- and cross-language generalization in Spanish--English bilinguals. Furthermore, we examined sources of individual variability that predicted word learning. Method: Nineteen Spanish--English bilingual children participated…

The current study investigated the possibility that language switches could be relatively automatically triggered by context. "Single-word switches," in which bilinguals switched languages on a single word in midsentence and then immediately switched back, were contrasted with more complete "whole-language switches," in which…
