Abstract

This longitudinal study investigates whether the development in executive control and bilingual experience predicts change in language control in bilingual children. Children we retested twice over the course of one year, using the language-switching paradigm and the Simon task. The participants were Japanese-English bilingual ‘returnee’ children (ages 7–13),who returned to their first language (L1) environment after spending some years in a second language (L2) dominant environment. Testing these children upon their return to the L1 environment allowed us to disentangle the effect of age from bilingual experience, as they experienced an increase in age but a decrease in L2 exposure over time. Children who had less L2 exposure showed smaller improvement in baseline performance when naming pictures in English (i.e., when English was relevant across all trials). Moreover, development in trials where children had to switch between languages were modulated by development in executive control. That is, children who increased their performance in the English mixed repetition trials also performed better on the executive control task over time. Thus,development in executive control modulated change in language control among bilingual children, suggesting a positive relationship between language control and executive control in children’s development
