Cross-site comparisons indicate that East Asian children typically excel on tests of executive function (EF), but interpreting this contrast is made difficult by both the heavy reliance on testing in school settings and by the scarcity of studies that assess across-site measurement invariance. Addressing these gaps, our study included remote…

This study evaluates the effectiveness of the "Parent-child Brain Camp," a 4-week video-based executive functions (EFs) training program for children ages 5-6, through a randomized controlled trial with a pre- and post-test design with 173 Hong Kong children (intervention "ni" = 79, 48.7% girls, M[subscript age] = 69.16 months;…

This study investigated the associations between infant frontal EEG power (5 month), infant visual attention (10 month), and toddler executive functioning (EF; 24 month), extending previous research predominantly conducted with school-aged children. Data were collected from 410 typically developing children (51% female; 78% White, non-Hispanic)…

This study examines associations between enrollment in high-quality PreK and growth in children's (N = 422; M[subscript age] = 5.63 years; 47% female; 15% Asian, 19% Black, 30% White, 31% Hispanic; 5% other or mixed race) academic, executive functioning, and social-emotional skills across kindergarten (2017-2018) and first grade (2018-2019).…

This cross-sectional study explored the relationship between 24-hour movement behaviors and executive function (EF) in preschool children. A total of 426 Han Chinese preschoolers (231 males; 3.8 ± 0.6 years old) from Zhuhai, Guangdong Province, China were selected from October 2021 to December 2021. Accelerometers were used to measure physical…

This study aimed to determine the effects of the Active Early Learning (AEL) childcare center-based physical activity intervention on early childhood executive function and expressive vocabulary via a randomized controlled trial. Three-hundred-and-fourteen preschool children (134 girls) aged 3-5 years from 15 childcare centers were randomly…

This study examined the link between classroom ethnic diversity, cross-ethnic friendships, and children's theory of mind. In total, 730 children in the United Kingdom (54.7% girls, 51.5% White) aged 8 to 13 years completed measures of theory of mind in 2019/2020. Controlling for verbal ability, executive function, peer social preference, and…
