Objective: Physical activity (PA) is essential to promote both optimal physical and emotional health in preschool children. Hence, well-founded PA guidelines are essential. 24-hour Movement Guidelines (which include PA, recreational screen time and sleep) have been established. Thus, this study aimed to explore preschool-aged children's adherence…

Preschoolers' prosocial behaviours support healthy interpersonal relationships as a component of their social adjustment process. Although several studies have found links between parental marital characteristics and preschoolers' prosocial behaviours, these conclusions were divisive. Therefore, a meta-analysis was conducted to clarify the…

Healthy relationships between parents and teachers are essential to addressing children's emotional and behavioral concerns. The current meta-analysis examined the effects of family-school engagement interventions on parent-teacher relationships. Twenty-three group-design studies yielding 58 effects comprised the current sample. Random effect…

Bjorklund and Kipp (1996) hypothesized that due to selection processes operative during human evolution, females have an inborn advantage over males in the ability to suppress inappropriate responses on tasks in the behavioral and social domains. To test this hypothesis, a meta-analysis was conducted on gender differences on simple delay tasks in…

We conducted a meta-analytic review of 53 studies published between 2000 and 2020 to quantify associations of parents' emotion regulation with parenting behavior and children's emotion regulation and internalizing and externalizing symptoms. Twelve meta-analyses, which included between 4 to 22 effect sizes (N from 345 to 3609), were conducted to…

Externalizing behavior and low academic performance present key developmental challenges for school-age children, with the potential for these domains to predict each other over time, leading to worsened outcomes. Yet, previous studies have yielded inconsistent conclusions about the directional pathways between externalizing behaviors and academic…

The Dimensional Change Card Sort (DCCS) task is a widely used measure of preschoolers' executive function. We combined data for 3,290 3-year-olds from 37 unique studies reporting 130 experimental conditions. Using raw pass/fail counts, we computed the pass rates and chi-squared value for each against chance (50/50) performance. We grouped data…

This systematic review investigates the effects of foreign language programmes in early childhood education and care (ECEC), which are increasingly popular. Foreign language ECEC centres familiarise very young children with a foreign language, and in general also expose them to the majority language. This review synthesises research on the effects…

Research on the effects of physical activity on children with attention deficit hyperactivity disorder is promising, yet no attempt has been made to integrate current findings using meta-analytic techniques. Using a meta-regression, the present study examined the effectives of physical activity for children with attention deficit hyperactivity…

The influence of a model's age on young children's behaviour has been a subject of considerable debate among developmental theorists. Despite the recent surge of interest, controversy remains about the nature of peer influence in early life. This article reviews studies that investigated the influence of a model's age on young…

The effectiveness of behavioural intervention programs for children with Autistic Spectrum Disorders was addressed by a meta-analysis, which reviewed 14 studies. The findings suggest that the behavioural programs are effective in improving several developmental aspects in the children, in terms of their treatment gains, and also relative to…

The research synthesis presented here reviewed the currently available evidence on the effectiveness of sibling-implemented interventions for their siblings with disabilities. The search for appropriate research literature spanned from 1975 to 2008 and resulted in a total of eight studies that met the inclusion criteria. All eight studies in this…

This meta-analysis of 69 studies (1,483 effect sizes) used random effects models to examine maternal employment during infancy/early childhood in relation to 2 major domains of child functioning: achievement and behavior problems. Analyses of studies that spanned 5 decades indicated that, with a few exceptions, early employment was not…

This article reviews research conducted on social comparison processes in the classroom since Festinger proposed his theory of social comparison. It covers the theoretical framework of social comparison theory, and it is organized around the following themes: motives for social comparison, dimensions of social comparison, direction of social…

Cognitive styles are broad, systematic characteristics that influence people's responses in different situations. Field dependence independence (FDI) is the cognitive style construct that has generated the most research. Describes the FDI characteristics in young children's social behaviors, including their social orientation, people-versus-object…
