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…

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…

Chimpanzees and other great apes seem to be much less cooperative than humans overall, yet they nevertheless reliably help others in many instrumental circumstances. Although in many contexts the helping behavior of chimpanzees is quite similar to that of human children, recent studies using both behavioral and psychophysiological paradigms have…

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…

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…

Parents are the primary source of support for their children and can become principal interventionists for preventing and treating their child's challenging behavior. Yet, providing adequate and adapted training for culturally diverse families can be difficult due to the increase of international migration and the diversity of languages spoken…

The present review aimed to examine cross-cultural differences (eastern vs western cultures) in the evaluation of antisocial and prosocial lies through two meta-analyses. A total of 10 studies consisting of 2,347 participants between 5 and 12 years of age were included. Both meta-analyses did not find significant cross-cultural differences on…

Children who engage in aggressive behaviors are at heightened risk of being involved in the justice system, committing serious offenses, and becoming chronic offenders. The Stop Now And Plan (SNAP) program was designed as an early intervention to address several mechanisms underlying the development of conduct problems, including emotion…

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…

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…

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 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…

Since Margaret Mead's field studies in the South Pacific a century ago, there has been the tacit understanding that as culture varies, so too must the socialization of children to become competent culture users and bearers. More recently, the work of anthropologists has been mined to find broader patterns that may be common to childhood across a…

Self-regulation is increasingly recognized as a key predictor of academic and social competence. A multidisciplinary understanding of this ability is timely and can strengthen theory and practice. The present review aims to inform educators on what cognitive neuroscience can teach us about self-regulation. To do so, we will focus on a decade-long…
