We examined the influence of bilingualism on task switching by inspecting various markers for task-switching costs. English monolinguals and Korean–English bilinguals completed a modified Dimensional Change Card Sort task based on a nonverbal task-switching paradigm. We found advantages for Korean–English bilinguals in terms of smaller single-task (pure-block) switch costs and greater reactivation benefits than those of English monolinguals. However, bilingual advantages in mixing costs were relatively weak, and the two groups did not differ on local switch costs. Notably, when we approximated the cue-based priming effect in single-task (pure) blocks, we found no evidence that the locus of bilingual advantages …

Although little is known about the link between bilingualism and mathematical achievement in children, the established link between executive functions (EFs) and mathematical achievement suggests that bilingualism—which has been shown to affect EFs—may positively predict math skills. Drawing on two large-scale datasets collected in the US—the Multi-State Study of Pre-Kindergarten and the State-Wide Early Education Programs (Study 1) and the Early Childhood Longitudinal Study (Study 2)—we examined the relation between bilingualism and mathematical achievement among preschoolers, kindergarteners, and first-grade students (ages 4–7), while controlling for key covariates of (a) demographic variables, such as age, gender, race/ethnicity, and socioeconomic status; and …
