Learning environments can support the development of foundational knowledge and promote children's attitudes toward learning and school. This study explores the relation between school enjoyment and general knowledge from preschool (2016-2017) to kindergarten (2017-2018) in 1359 children (M[subscript age] = 55, 61 months, female = 50%; 58.5%…

Purpose: Systematic reviews of literature are routinely conducted to identify practices that are effective in addressing educational and clinical problems. One complication, however, is how best to combine data from both group experimental design (GED) studies and single-case experimental design (SCED) studies. Percent of Goal Obtained (PoGO) has…

This study investigated whether transitory and persistent poverty spells were associated with children's learning (literacy and numeracy scores) and executive function outcomes in Ghana. Children resided in the Greater Accra region (N = 2,154; 49% female; M[subscript age] = 5.2 years at wave-1) and were followed at four-time points over three…

In the target article, Xing and colleagues (2021) claimed that 6- to 8-year-olds who spontaneously referenced the midpoint of 0-100 number lines made more accurate magnitude estimates and scored higher on a standardized math achievement test than other children. Unlike previous studies, however, the authors found no relation between accuracy on…

We investigated the impact of a subsidized, needs-based preschool program (Study 1; N = 1,894) and California's universal but age-restricted transitional kindergarten (TK) program (Study 2; N = 1,093) on school readiness. We applied Mahalanobis matching--a quasi-experimental data analysis method used to create equivalent groups--to data from three…

There is scant empirical work on associations between current and past cannabis use in parents of young children. As recreational cannabis use is now legal in nearly half of states in the U.S., cannabis use is becoming more ubiquitous. In the current study, parents of toddler and pre-school age children were randomly assigned to participate in an…

This study evaluated the effectiveness of Incredible Years® (IY) programs for ADHD in children aged 3-8 years based upon a systematic literature review. Effects of IY programs for children with or at-risk for ADHD are examined in addition to the impact on ADHD behaviors in young children identified as having conduct problems or disruptive…

Play is a powerful influence on children's learning and parents can provide opportunities to learn specific content by scaffolding children's play. Parent-child synchrony (i.e., harmony, reciprocity and responsiveness in interactions) is a component of parent-child interactions that is not well characterized in studies of play. We tested whether…

Recent national focus on early childhood science education highlights the need for research on early science, particularly with children from low-income families, as science is the lowest performing school readiness domain in that population. Given this achievement gap, the Office of Head Start has emphasized the development of children's…

ASD symptomology and behavioral problems pose challenges for children with ASD in school. Disagreement between parents and teachers in ratings of children's behavior problems may provide clinically relevant information. We examined parent-teacher disagreement on ratings of behavior problems among children with ASD during the fall and spring of the…

This study examined the prevalence of ADHD symptoms and anxiety as reported by parents and teachers for 180 preschool children (ages 4-5) and school-aged children (ages 6-7) with ASD using the Child Behavior Checklist--Parent and Teacher Report Forms (Achenbach and Rescorla, Manual for ASEBA school-age forms & profiles, Research Center for…

Because math knowledge begins to develop at a young age to varying degrees, it is important to identify foundational cognitive and academic skills that might contribute to its development. The current study focused on two important, but often overlooked skills that recent evidence suggests are important contributors to early math development:…

Early writing is important to young children's development -- research indicates that writing is predictive of later reading and writing. Despite this, preschool teachers often do not focus on writing and offer limited scaffolding to foster children's writing development. This article shares innovative ways to scaffold early writing across the…

Selective sustained attention (SSA) is crucial for higher order cognition. Factors promoting SSA are described as exogenous or endogenous. However, there is little research specifying how these factors interact during development, due largely to the paucity of developmentally appropriate paradigms. We report findings from a novel paradigm designed…

The goal of this study was to examine the extent to which preschoolers with externalizing behavior problems (EBP) can identify behaviors indicative of callous-unemotional (CU) traits among their peers. Participants for this study included 86 preschool children (69% boys; M[subscript age] = 5.07 years) with at-risk or clinically elevated levels of…
