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 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…

This coda considers how translanguaging discourse is manifested in classrooms. Li Wei and Lin open up spaces of possibility for translanguaging by questioning the order of language. In so doing, the school code assumes its appropriate place as a system of coloniality.

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…

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…

Purpose: The current study examined language control and code-switching in bilingual children with developmental language disorder (DLD) compared to bilingual peers with typical language development (TLD). In addition, proficiency in each language and cognitive control skills were examined as predictors of children's tendency to engage in…

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…

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…

Switching language is costly for bilingual speakers and listeners, suggesting that language control is effortful in both modalities. But are the mechanisms underlying language control similar across modalities? In this study, we attempted to answer this question by testing whether bilingual speakers incur a cost when switching to a different…

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…

Acquisitionists generally assume a relation between code-mixing in young bilingual and trilingual children and language dominance. In our cross-sectional study we investigated the possible relation between code-mixing and language dominance in 122 children raised in Spain or Germany. They were bilingual, trilingual or multilingual, the latter…

Emergent bilinguals' engagement and participation with learning is closely connected to the identities they are able to construct in this learning. In this paper, I present a model for understanding how young emergent bilinguals begin to construct identities with language and learning across school-based activities. Drawing upon Holland,…
