The Role of Internal and External Factors for Code-Switching: A Study of Early Multilingualism in Germany with Special Reference to Catalan as a Heritage Language

Abstract

In heritage language acquisition studies, it has been observed that heritage speakers may experience a shift of language dominance from the heritage language to the majority language due to input quantity and quality factors. The appearance of code-switching in the productions of multilingual speakers has been well attested and has been mostly linked to age and language dominance as well as family language policies and consistence of input, among other factors. For the appearance of code-switching, our cross-sectional study analyses language dominance (MLU) and fluency (w/minute) along with child-external factors, such as family language policies, family language and siblings’ interaction, in sixteen multilingual children (mean age 5;7) being raised in Germany with German and Catalan (and another L1) simultaneously. In a nutshell, children who are dominant in the majority language ultimately code-switch more frequently than the other groups. Interestingly, balanced and heritage-language-dominant children present instances of intrasentential code-switching (particularly insertions and alternations), while intersentential code-switching is frequent across all groups. When families have chosen the ‘one person-one language’ strategy and do not have a family language, code-switching is almost absent. Finally, sibling groups using both the heritage and the majority languages in their interactions show low code-switching rates.
