Purpose: In the current study, we examined the alignment of language choice of bilingual parent-child dyads in play-based interactions. Method: Forty-four bilingual Spanish-English parent-child dyads participated in a 10-min naturalistic free-play interaction to determine whether bilingual children and their parents respond to each other in the…

This study investigates perception and production of the Catalan mid-vowel /e/-/[epsilon]/ contrast by two groups of 4.5-year-old Catalan-Spanish bilingual children, differing in language dominance. Perception was assessed with an XAB discrimination task involving familiar words and non-words. Production accuracy was measured using a familiar-word…

Postsecondary education in Canada is mostly provided in institutions that offer courses and programs in one of the two official languages, English or French. Is there a link between the language of instruction of the postsecondary institutions attended by students and the language choices they make in the workplace after their studies? Since the…

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…

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…

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…

We longitudinally examined the trajectories of Latine mothers' (N = 116) language input to their children during book-sharing interactions at four points in development, when children were between ages 2 and 5 years. Mother-child dyads were video-recorded sharing a wordless picture book, and transcriptions of mothers' and children's language…

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…

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…

Singapore is an ethnically, linguistically, and culturally diverse nation-state that has always practiced deliberate language policy and planning. The bilingual education policy, introduced shortly after the young nation's independence has led to the emergence of English-knowing bilinguals who are proficient in both English and their ethnically…

Even though engineering and science are tasked with developing solutions and knowledge for a diverse population, Black and Brown communities remain severely underrepresented in these disciplines. The problem exceeds easy solutions like "a seat at the table" and requires rethinking with whom and for whom the field designs ideas and…
