Book Description

It has long been established that bilingual speakers are rarely balanced in their languages so that one language is dominant. The contributions to the Research Topic “Bilingual Language Development: The Role of Dominance” focus on the potential effects of language dominance on the competence and processing of bilinguals, covering a large variety of language combinations and domains. Important aspects of such work are the interplay of L1-maintenance/attrition and possible L2-dominance, the direction of cross-linguistic influence (CLI) or code-mixing, as well as the effects of bilingualism on cognitive development, each addressed in several contributions. However, such research presupposes a definition of dominance, which is far from being settled. This gives rise to considerable differences in the operationalization of the concept across studies. The studies in this Research Topic present a multifaceted picture of the role of language dominance for L1-maintenance/attrition, L2-development and CLI. Though a unified story cannot emerge for such a complex subject, interesting new venues are explored including the impact of dominance shift during L1-re-exposure, comparisons of different types of bilingual groups, or operationalization of dominance through experiential measures. The variety of approaches and results is in part owed to the many language combinations studied and the fact that bilingual children, adults and atypical speakers are investigated. This diversity constitutes the interest of this Research Topic.
