Imitation plays a crucial role in early social learning. Numerous studies indicate that young children copy even actions that are clearly irrelevant for goal achievement--a phenomenon called overimitation (OI). The present study tested whether this finding can be generalized to different forms of faithful nonsense imitation presented in different…

Although exploratory play is considered a hallmark of cognitive development and learning, relatively few studies have been able to quantitatively characterize the shifts that may occur in children's approach to exploration. One reason for this gap is due to challenges coding and analyzing children's exploratory play behavior. In our paper, we…

Children with a history of behaviorally inhibited (BI) temperament face a heightened risk for anxiety disorders and often use control strategies that are less planful. Although these relations have been observed concurrently in early childhood, middle childhood, and adolescence, few studies leverage longitudinal data to examine long-term…

Children are exposed to many trace elements throughout their development. Given their ubiquity and potential to have effects on children's neurodevelopment, these exposures are a public health concern. This study sought to identify trace element mixture-associated deficits in learning behavior using operant testing in a prospective cohort. We…

Understanding executive functions (EFs) development is of high value to global developmental science. Recent calls for a more inclusive and equitable developmental science argue that tasks and questionnaires that are developed using only a subset of the population are not likely to be appropriate for EFs measurement in global contexts unless…

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…

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…

Background: Parenting strategies such as communicating clear expectations, providing calm directions, and teaching specific skills can strengthen young children's social-emotional development. Parenting programs for children with disruptive behavior often emphasize gaining compliance via effective directives, and less on how to facilitate child…

This study used a person-centered approach to examine mother-daughter dyad behaviors when jointly solving addition problems during a card game. The goal was to identify maternal and child profile behaviors during the interaction as predictors of children's autonomous addition accuracy and strategy use at the end of first grade. Videotaped…

This study examined early development of cool and hot self-regulation and how they were related to Chinese preschoolers' early achievement. A total of 951 children (448 girls) aged three to five in Hong Kong participated in this study. Children's self-regulation was assessed with a battery of five tasks tapping either cool or hot self-regulation;…

This study examined young children's contact with individuals of high-wealth and low-wealth backgrounds and their behavior toward peers of these backgrounds in a resource distribution task. The sample included 72 ethnically diverse higher income children (M[subscript age] = 6.68 years, SD = 0.98 years). Contact with individuals of low-wealth…

This study examined future-oriented behavior in children (3-6 years; N = 193) from three diverse societies--one industrialized Western city and two small, geographically isolated communities. Children had the opportunity to prepare for two alternative versions of an immediate future event over six trials. Some 3-year-olds from all cultures…

Although high-quality early care and education (ECE) is widely accepted as one of the most effective means for promoting early learning and development, many ECE programs have limited impact perhaps because of issues with how ECE quality is defined and measured. This study seeks to expand definitions of ECE quality by asking which preschool ECE…

Three hundred and forty-one children (M[subscript age] = 9,0 years) engaged in a series of science tasks in collaborative, same-sex pairs or did not interact. All children who collaborated on the science tasks advanced in basic-level understanding of the relevant task (motion down an incline). However, only boys advanced in their conceptual…

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…
