Working memory is an often studied and important psychological construct. The growth of working memory capacity (WMC) in childhood is described as linear. Average adult WMC is estimated as either four or five "chunks." Using latent curve models of data from a measure of digit span backward that was administered longitudinally to a large…

Early onset of internalizing and externalizing behavior problems is associated with persistent and more severe academic, social, and mental health challenges later in life. Understanding the factors that increase children's risk of developing these behavior problems prior to the start of formal school is important for preventing their emergence…

Using the Early Childhood Longitudinal Study Kindergarten Cohort (2010-2011), this study is the first to investigate predictors of kindergarten science achievement and growth across elementary school--English language proficiency (ELP), executive functioning, math and reading achievement, parent-engaged science and math activities, and classroom…

Using the data from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011), this paper proposes to theoretically redefine and empirically capture the concept of emotional capital as it applies to students, employing five components (engagement, school belonging, grit, peer social support, and life satisfaction). The…

Achievement gaps in learning can be identified as early as entry into kindergarten. This longitudinal study explored reading outcomes of 60 students over the course of five years to determine the impact of an additional year of school prior to kindergarten. The program was created to provide alternative options for students who attended preschool…

Children's early numerical competencies are of great importance for later academic achievement. Young children gain these competencies in the context of the home numeracy environment (HNE). Additionally, child characteristics and families' socioeconomic status (SES) are associated with children's competencies. In this study, we investigated…

While states have developed policies around a cut-off date for kindergarten entrance, some parents chose to have their child enter kindergarten before this date (Early Entrance) as an acceleration technique, or hold the child back from entering, a practice termed Redshirting, to allow for greater maturity and increased achievement in relation to…

Inequities have existed in formal public education since its inception in the United States. The educational experiences and outcomes for Black students have historically lagged behind their non-Hispanic, and White peers. This dissertation uses data from The Early Childhood Longitudinal Survey for the Kindergarten Class of 2011 (ECLS-K: 2011) to…

This study investigated the longitudinal associations between children's early mathematics and their home numeracy environment (HNE). Chilean children from families who varied widely in socioeconomic status were assessed at the beginning and end of prekindergarten in 2016 (N = 419, M[subscript age] = 4:7 [years:months]), and at the end of…

This 13-month longitudinal study investigated whether different phonological processing components independently predicted individual differences in Chinese word reading and arithmetic. Three phonological processing skills [phonological awareness, phonological memory, and rapid automatized naming (RAN)], word reading, and arithmetic were assessed…

Theory of mind has received intensive attention in research as an important skill to develop. Furthermore, recent evidence indicates its role in discourse comprehension. In the current study, we examined the mediating role of theory of mind in the relations of foundational language and cognitive skills (working memory, attentional control,…

This study compares mathematics instructional practices in classrooms that do and do not contain students with high-incidence disabilities (HIDs). To do so, we examined a national data set of responses from kindergarten teachers about instructional practices. We do find that in classrooms with students with HIDs, teachers reported different…

Guided by models of family unpredictability, this study was designed to identify the distinctive sequelae of disorganized interparental conflict, a dimension of interparental conflict characterized by abrupt, inexplicable changes in parental emotional lability, conflict tactics, and verbalizations. Participants included 208 kindergarten children…

This study explored how one teacher's instructional strategies and perceptions about STEM investigations with kindergarten children evolved over the course of three years of participation in the NURTURES professional development program. The purpose of this study was to gather and share useful information about the effects of long-term…

Research in developmental psychology often contains samples where education and income are highly related. This study examines characteristics of low-income families who have at least one parent with a college education and how their children's achievement and parenting practices compare to other types of families. Using the Early Childhood…
