Recent research has provided mixed evidence on the promise of classroom-based interventions for supporting young children's development of executive functions (EF). To advance intervention efforts, it is necessary to identify specific types of interactions that might support the development of EF in early childhood. Through a correlational design,…

During imaginative play, children may learn foundational skills important for academic success. Indeed, imaginative children, high in fantasy orientation (FO), may have advantages in skills that support positive classroom and social behavior. Yet findings are mixed regarding the classroom behavior of children high in fantasy orientation. The…

Research Findings: The present study explored connections between participation in structured open-skilled (e.g., soccer, basketball) and closed-skilled sports (e.g., swimming) and executive function (EF) among preschool-aged children. The sample included 197 preschool-aged children (mean age = 4.34 years, female = 48.2%, White = 83.8%). Parents…

Research Findings: A substantial body of research has demonstrated social and academic benefits of sociodramatic play (SDP) for young children. However, substantially less research has explored the factors related to increased amounts of SDP occurring during free play, an activity time that comprises the greatest portion of the daily schedule in…

Responding to a robust body of literature suggesting that children's early educational experiences are critical, policymakers have implemented and expanded the provision of full-day kindergarten (FDK) in recent decades. Most studies have focused on the effectiveness of FDK on child academic assessments or test scores, but none have examined FDK…

Research Findings: Optimal sleep is important for children's learning and development. "Sleep disordered breathing" (SDB) refers to a spectrum of conditions from simple snoring to obstructive sleep apnea that is common in childhood and interrupts sleep. We examined pathways between SDB and academic performance of children (N = 163, M…

Research Findings: This study examined the learning effects of collaborative group work under heterogeneous group composition among 5-year-old children, especially in terms of their social skills. To this end, the study utilized an experimental research design wherein 3 groups of differently composed dyads and a group of students who worked alone…
