Recent genetic discoveries offer a new lens through which to study cognitive, emotional, behavioral, and social processes that are foundational to children's development. In this article, we review the latest advances in genomics--genome-wide association studies and the polygenic scores that have come out of them--and discuss how these techniques…

Purpose: This study tested whether the Sitting Together and Reaching to Play (START-Play) physical therapy intervention indirectly impacts cognition through changes in perceptual-motor skills in infants with motor delays. Methods: Participants were 50 infants with motor delays randomly assigned to START-Play plus Usual Care Early Intervention…

Social-emotional learning (SEL) and character education are important components of adolescent development. In this study, we evaluated a randomized controlled trial of CharacterStrong, a curriculum that combines SEL and character education that included 1609 students and 242 teachers across 14 schools. This study applied baseline target…

Objective: Our objective was to evaluate the efficacy of the Sitting Together and Reaching to Play (START-Play) intervention in young infants with neuromotor disorders. Method: This randomized controlled trial compared usual care-early intervention (UC-EI) with START-Play plus UC-EI. Analyses included 112 infants with motor delay (55 UC-EI, 57…

It is often argued that metacognition includes 2 components: monitoring and control. However, it is unclear whether these components can operate independently, or whether they always operate as part of a hierarchy. The current study attempts to address this issue. In Experiment 1 (N 90), age-related differences were assessed to examine the…

Perceptual judgments result from a dynamic process, but little is known about the dynamics of number-line estimation. A recent study proposed a computational model that combined a model of trial-to-trial changes with a model for the internal scaling of discrete numbers. Here, we tested a surprising prediction of the model--a situation in which…

Kim and Opfer (2017) found that number-line estimates increased approximately logarithmically with number when an upper bound (e.g., 100 or 1000) was explicitly marked (bounded condition) and when no upper bound was marked (unbounded condition). Using procedural suggestions from Cohen and Ray (2020), we examined whether this logarithmicity might…

This article reports on an exploratory study of the shifts of teachers' interactions with boys from their first to their second year of using cognitively guided instruction (CGI) in their math instruction. Interaction analysis was used to analyze 22 videos, two per each of 11 teachers, who applied CGI instruction in their classrooms (a) after…

Across geographically diverse samples, engagement in stimulating activities with young children is considered an important element of parenting that promotes cognitive, behavioral, and social-emotional development. Indicators of stimulation activities are often summed, based on the assumption that more stimulation is better and that different…

Biological psychiatry, like many other scientific fields, is grappling with the challenge of revising its practices with an eye towards promoting diversity, equity, and inclusivity (DEI). One arena in which much of this work will have significant impact is in developmental science generally, and the study of adolescence specifically. Adolescence…

The present study investigated the relationship between adverse childhood experiences and reading comprehension as well as the relationship between current trauma symptoms and reading comprehension. Each of these relationships were investigated as being mediated by academic metacognition (i.e., knowledge and regulation of cognition while…

This secondary analysis of data from a randomized control trial of an early mathematics intervention, ROOTS, explored whether patterns of intervention response were best categorized by the typical response/non-response binary or a more complex framework with additional response profiles. Participants included kindergarten students at risk for…

The integrated theory of numerical development posits that a central theme of numerical development from infancy to adulthood is progressive broadening of the types and ranges of numbers whose magnitudes are accurately represented. The process includes four overlapping trends: 1) representing increasingly precisely the magnitudes of non-symbolic…

"Patterning" is a cognitive intervention that is unknown to psychologists, but has nevertheless been taught for half a century in nearly all kindergartens and many preschools in English-speaking countries. Patterning is the understanding that a certain rule governs the sequence of items in a series. At the simplest level, if the series…

Developmental science demonstrates that younger children (ages 4 to 8) are capable of making meaning of their contexts and the self. Yet, younger children's meaning making is largely absent from intervention and implementation research on early childhood policies. This absence is notable given the rise in investment in early childhood policies and…
