Across geographically diverse samples, engagement in stimulating activities with young children is considered an important element of parenting that promotes cognitive, behavioral, and social-emotional development. Indicators of stimulation activities are often summed, based on the assumption that more stimulation is better and that different…

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,…

The current study examines the contributions of family context (e.g. life events, home environments) to low-income preschool children's self-regulation (behaviour regulation and executive function) in the United States and Turkey. Participants were 1139 low-income children (486 from the U.S. and 653 from Turkey) and their parents. Children's…

This study extends the methodological and theoretical understanding of executive functions (EFs) in preschoolers from low- and middle-income countries (LMIC). First, the authors describe a rigorous process of adapting and evaluating six EF tasks to produce a culturally and developmentally appropriate measure of emerging EFs in a large sample of…

Background: Prior research suggests that 60-74% of males and 16-45% of females with fragile X syndrome (FXS) meet criteria for autism spectrum disorder (ASD) in research settings. However, relatively little is known about the rates of clinical diagnoses in FXS and whether such diagnoses are consistent with those performed in a research setting…

Intervention studies indicate that children's childcare experiences can be leveraged to support the development of executive functioning (EF). The role of more normative childcare experiences is less clear. Increasingly, theory and empirical work suggest that individual differences in children's physiological stress systems may be associated with…
