Current literature and research demonstrates that learning multiple languages allows for young learners to develop higher levels of executive functioning skills. Research also suggests that Dual Language Learners (DLLs) can surpass monolinguals in these executive functioning skills. Yet, there is a dearth of literature that explicitly discusses DLLs in the early childhood setting and the development of self-regulatory skills. Self-regulation skills have been linked to better indicators of academic achievement than numeracy and literacy. This research describes the differences between DLLs' behavioral and emotional regulation, which are categorized as impulse control and cognitive regulation. This analysis examines the development of cognitive regulation and impulse control in both DLLs and non-DLLs. Results from an ANOVA of a convenience sample of 63 participants, 32 DLL (English and Spanish) and 31 non-DLL (English) preschool students, were assessed using the "Preschool Self-Regulation Assessment" (PSRA) and several measures of oral language proficiency. Participants were drawn from a Head Start and Universal Pre-Kindergarten program located in a low SES and culturally diverse district. The result yielded a statistically significant effect, (F(1, 61) = 8.56, p = 0.005; partial Eta squared = 0.123) for non-DLLs. ANOVA results suggest differences in cognitive regulation between the two groups. Implications relating to self-regulation, DLLs, culture and classroom practice, as well as policy are further discussed.
