Performance on a range of spatial and mathematics tasks was measured in a sample of 1592 students in kindergarten, third grade, and sixth grade. In a previously published analysis of these data, performance was analyzed by grade only. In the present analyses, we examined whether the relations between spatial skill and mathematics skill differed…

The COVID-19 pandemic created unprecedented disruptions to school systems around the globe and Virginia's public school system was no exception. These disruptions likely impacted families' decisions about whether and where to enroll their children in public schools. However, many basic facts about how public school enrollment changed in the…

Objectives: The importance of breastfeeding exposure and children's development of self-regulation, independently, are well established. Each of these domains also has been linked to better cognitive development and academic achievement in children. However, little is known about how breastfeeding affects development of early self-regulation…

There are large differences in expulsions and suspensions on the basis of race starting in preschool and divergent explanations for their cause. The current study explores how developmental methodology can shed light on this vexing issue. We leverage two measures: (1) childcare provider complaints about children's behavior and their recommended…

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%…

In a recent empirical article published in "Cognition" (Johnson, Burgoyne, Mix, Young, and Levine [2022]. "Cognition," 218, 104918), we examined the relationships between spatial and mathematics skills in a cross-sectional sample of 1,592 children that included kindergarteners, third graders, and sixth graders. We tested…

Much recent research has focused on the relation between spatial skills and mathematical skills, which has resulted in widely reported links between these two skill sets. However, the magnitude of this relation is unclear. Furthermore, it is of interest whether this relation differs in size based on key demographic variables, such as gender and…

Purpose: Having a clear understanding of the types and amounts of classroom literacy learning opportunities is important for contextualizing children's early literacy performance. In this study, we examine the content, context, and management of literacy learning opportunities in a large, geographically diverse sample in the United States. We also…

The "remembered success effect" (Finn, 2010) refers to the finding that challenging academic tasks that start or end with extra opportunities for success are preferred to challenging tasks that do not include these opportunities. Work on remembered success has primarily been done with adults. We assessed (in a preregistered study)…

Research Findings: The amount of time and type of program that children experience in early childhood settings may be associated with children's kindergarten-entry skills, or kindergarten readiness. Taking a person-centered perspective, in the present study, we examined the extent to which reliable and unique profiles of early childhood…

The COVID-19 pandemic drastically disrupted the functioning of U.S. public schools, potentially changing the relative appeal of alternatives such as homeschooling and private schools. We study changes in families' choices of school sector using longitudinal student-level administrative data from Michigan and nationally representative data from the…

We evaluated the efficacy of Early Language Comprehension Individualized Instruction (ELCII), a supplemental computer-based early language comprehension intervention, in improving kindergarten students' inference making performance. In Study 1, students completed ELCII modules over nine weeks, whereas a business-as-usual control group engaged in…

This study examined the unique and interactive effects of teacher-child relationships and classroom quality on PreK to Grade 1 children's reading and math achievement, social skills, and problem behaviors, as well as whether these relationships differed by children's race and ethnicity. Based on data from 192 children (18.23% Black, 8.33% Latine…

Children's memberships in social groups have profound effects on their motivation. Stereotypes about social groups shape children's beliefs about what is expected for their group members. These beliefs can influence children's developing beliefs about themselves (self-perceptions). In this article, I review research on how gender stereotypes…

The present study examined whether teacher-child closeness and conflict across kindergarten and first grade varied by gender and disruptive behavior at kindergarten entry within a sample of 324 predominantly Black children from low-income, urban households. Three main findings emerged from the analyses. First, contrary to findings from previous…
