Spanish Formal Features in the Mind of Bilingual Children in Two Spanish–English Contact Zones

We explore how Spanish gender features are processed by English–Spanish bilingual children from two contact zones (Sotogrande, Spain, and Gibraltar, United Kingdom), divided into two dominance groups. The children come from two schools in which both languages are spoken, while English is the language of instruction. We present offline and online processing data involving linguistic code-switching between subjects and adjectives (Adj) in copulative constructions (the window es is roja red). Two issues are targeted to explore the mental representation that bilinguals have when their two languages are simultaneously activated. (i) The directionality of the switch provides information as to whether or not having to value gender features should result in a more economical representation. (ii) The gender agreement mechanisms that could be enforced when a Spanish adjective switch is processed provide information as to the importance that gender feature valuation has for bilinguals. Data show that no differences appear across the two child groups, which suggests that dominance does not reflect the similar representation that the two bilingual groups seem to have. The preference for English Adj switches and for gender matching Spanish Adj switches is linked to the properties of the two languages involved in the switch and to the hierarchy of processing difficulties.
