Background: Children in foster care are at high risk of future mental health and developmental difficulties. A number of interventions may be helpful; however, the effectiveness of interventions specifically for pre-school children in foster care is not well established. This is an important omission, since infancy and early childhood may be the…

Mapping skills between different codes to represent numerical information, such as number symbols (i.e., verbal number words and written digits) and non-symbolic quantities, are important in the development of the concept of number. The aim of the current study is to investigate children's mapping skills by incorporating another numerical code…

Research on factors underlying socioeconomic status (SES)-related inequalities in child development mainly focuses on single countries and specific influential factors. Only few studies scrutinize to what extent differences in children's early behavioural outcomes vary across countries and whether the processes that account for them are common or…

The author contends that, although most early childhood educators agree about the value of play for child development, preschools and kindergartens often do not reflect this belief, and she discusses this anomaly in the adult notion of play and how it manifests in classroom practices. She argues that it produces schoolroom practices in which…

Executive functions (EF) are crucial to regulating learning and are predictors of emerging mathematics. However, interventions that leverage EF to improve mathematics remain poorly understood. 193 four-year-olds (mean age = 3 years; 11 months pre-intervention; 111 female, 69% White) were assessed 5 months apart, with 103 children randomised to an…

The development of young children's counting has been extensively researched, yet detailed studies that examine development over multiple years are curiously absent from the literature. This research examined 15 preschoolers' (ages 3-4) use of number words as they engaged in two counting tasks, an oral counting task and counting a collection of 31…

Background: Several studies have reported low adherence to World Health Organization sedentary behavior (SB) guidelines in the early years. The purpose of this review is to examine the associations between time spent in different types of SB (screen time and habitual SB) and motor competence (MC; fundamental motor skills, fine and gross motor…

Perspective taking and cognitive flexibility are important abilities for navigating our everyday lives. In this longitudinal study with 108 children (61 girls, mostly White), we investigated the developmental relation between Level 1 perspective taking at 27 months of age and Level 2 perspective taking at 52 months of age as well as relations to…

The purpose of this study is to explore a theoretical idea in relation to a body of empirical material from a reading activity involving a picturebook on shadow. The theoretical idea, sprung from variation theory, entails children's discernment through synchronic simultaneity as a key to their ability to imagine. To explore this idea, an analysis…

Disparities in socioeconomic status (SES) may affect individuals' risk preferences, which have important developmental consequences across the lifespan. Yet, previous research has shown inconsistent associations between SES and risky decision-making, and little is known about how this link develops from a young age. The current research is among…

This study evaluates the effectiveness of the "Parent-child Brain Camp," a 4-week video-based executive functions (EFs) training program for children ages 5-6, through a randomized controlled trial with a pre- and post-test design with 173 Hong Kong children (intervention "ni" = 79, 48.7% girls, M[subscript age] = 69.16 months;…

Aim/Purpose: This study explores the effectiveness of a virtual reality (VR) application designed to teach Theory of Mind (ToM) skills to children aged 5-6, addressing the gap in research on the use of VR for typically developing children. Background: ToM is a critical skill for social interaction and understanding others' perspectives. Despite…

In this longitudinal study, we investigated the factor structure and stability of early-life temperament in a German sample, using three measures developed within Rothbart's psychobiological approach. Temperament was measured using the Infant Behavior Questionnaire Revised (IBQ-R) at the ages of 6 and 12 months, the Early Childhood Behavior…

Despite previous studies showing that children's development of executive function (EF) skills is associated with the differing contexts in which children live, evidence about the independent and synergistic effects of families and neighborhoods is limited. Using a sample from a two-cohort longitudinal study of preschoolers from low-income…

The author draws on Lev S. Vygotsky's conception of play and Gunilla Lindqvist's methodology concerning the aesthetics of play to discuss play practice in early childhood classrooms. Based on the study of an educational experiment at a primary school, she discusses how children in a school setting simultaneously engage in developed forms of…
