Spatial play in early childhood is associated with a variety of spatial and cognitive skills. However, these associations are often derived from studies in which different tasks are used across different age ranges, leaving open the question of how children's natural behaviors during spatial play develop from infancy into the early preschool…

The results of studies on early competences suggest that the child's delay of gratification (DoG) ability is a major predictor of school readiness (SR). However, there are no direct data or convincing explanations as to how DoG translates into preschool children's readiness to commence school education. Aiming at a better understanding of the…

Fine motor skills develop in childhood. In this study, we evaluate motor planning in 6- to 11-year-old children using a pegboard and midline crossing task. The results of the pegboard task showed that children modified their strategies of hand use and space use as a function of age, albeit with a transition in the 8- to 9-year-old children. The…

Inhibitory control has been widely studied in association with social and academic adjustment. However, prior studies have generally overlooked the potential heterotypic continuity of inhibitory control and how this could affect assessment and understanding of its development. In the present study, we systematically considered heterotypic…

Around their first birthdays, infants begin to point, walk, and talk. These abilities are appreciable both by researchers with strictly standardized criteria and caregivers with more relaxed notions of what each of these skills entails. Here, we compare the onsets of these skills and links among them across two data collection methods: observation…

Children hold strong ingroup biases from a young age, liking ingroup over outgroup members and preferring them as social learning models. Simultaneously, children are also highly prosocial--both in their own helping behaviors and their avoidance of those who behave antisocially. This study explores how children of 2 age groups (4-5 and 7-8 years)…

Findings from previous cross-sectional studies showed that while toddlers around their first birthday imitate selectively, that is, they systematically omit some kinds of target action steps or they copy only the goal, but not the means of the modeled actions, older toddlers imitate more exactly. The aim of the present article is to provide…

Retrospective parental reports are common in the developmental science literature, but their validity has been questioned. We investigated the consistency of retrospective maternal recall by comparing original with retrospective maternal reports in three domains (maternal cognitions, mother-reported child and mother behaviors, and observed child…

In the present investigation, we studied the development of 6 physically aggressive behaviors in infancy and toddlerhood, posing 3 questions (a) How do the prevalences of individual physically aggressive behaviors change from 8, 15, and 24 months? (b) Are there groups of children who show distinctive patterns in the way individual physically…

Interpretations of Vygotsky's texts have generally focused on the intellectual aspects of children's development, including his theory of play. This article presents a reinterpretation of Vygotsky's theory of play and draws on this theory of art to include emotions as an important part of children's play. I will argue that in play, children's…

Previous research has found that when children engage in social and moral transgressions, they take steps to either remedy or explain their behavior. However, no prior systematic investigation has examined the strategies children employ to 'correct' their behavior in future situations. The present study employed a domain theory lens to investigate…

Humans possess a tendency to rapidly and consistently make character evaluations from mere facial appearance. Recent work shows that this tendency emerges surprisingly early: children as young as 3-years-old provide adult-like assessments of others on character attributes such as "nice," "strong," and "smart" based…

Learning to behave in socially competent ways is an essential component of children's development. This study examined the relations between children's social, communicative, and cognitive skills and their behaviours during a cooperative task, as well as how these relationships change at different ages. Early school-age (5-8 years old) and middle…

Early intervention (EI) and early childhood special education (ECSE) practitioners participating in the Child Outcomes Summary (COS) process must understand age-expected development, the ages at which children typically acquire different skills. This resource provides answers to commonly asked questions about age anchoring as it applies to the COS…

"The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5)," requires that symptoms of ADHD must be "developmentally inappropriate" in order for an ADHD diagnosis to be considered. Because the DSM-5 does not specifically outline procedure for determining developmental inappropriateness of behaviors,…
