This study explored differences in sustained top-down attentional control (i.e., proactive control) and spontaneous types of control (i.e., reactive control) in bilingual and monolingual speakers. We modified a Color-Word Stroop task to varying levels of conflict and included switching trials in addition to more "traditional" inhibition Stroop conditions. The task was administered during scalp electroencephalography (EEG) to evaluate the temporal course of cognitive control during trials. The behavioral Stroop effect was observed across the whole sample; however, there were no differences in accuracy or response time between the bilingual and monolingual groups. Event-related potentials (ERPs) were calculated for the N200, N450, and conflict Sustained Potential (SP). On the pure-blocked incongruent trials, the bilingual group displayed reduced signal during interference suppression (N450) and increased later signal, as indexed by the conflict SP. On the mixed-block incongruent trials, both the bilinguals and monolinguals displayed increased later signal at the conflict SP. This suggests that proactive control may be a default mode for bilinguals on tasks requiring inhibition. In the switching trials, that place high demands on the executive control component of shifting, the language groups did not differ. Overall, these results suggest processing differences between bilinguals and monolinguals extend beyond early response inhibition processes. Greater integration of proactive and reactive control may be needed to sort conflicting language environments for bilinguals, which may be transferring to domain-general mechanisms., (© 2021 Society for Psychophysiological Research.)

Research Findings: Greater self-regulation has been identified as a protective factor for low-income children's academic achievement. However, we know less about the long-term protective nature of specific aspects of self-regulation. Data were drawn from predominantly African American and Latino children in low-income communities in Boston, Chicago, and San Antonio during early childhood (mean age = 4.84 years) and middle childhood (mean age = 9.30 years; n = 348). The current investigation found that preschoolers' overall self-regulation predicted their academic skills in middle childhood, net of child and family characteristics as well as academic competence during preschool. Furthermore, when executive function (EF) and effortful control (EC) in early childhood were examined as simultaneous predictors of quantitative and literacy scores during middle childhood, there were moderate linkages from EF to both academic domains. Practice or Policy: Our findings suggest that the long-term gains of interventions that focus on fostering global self-regulation in preschool may yield more benefits for math than for reading, especially if such programs target young children's executive function in particular.
