There are long-held concerns regarding the impact of screen media on children's cognitive development. In particular, fast pace and fantastical events have been theorized to deplete children's cognitive resources, leading to reductions in their attention and executive functions (EF). To date, however, empirical tests of short-term effects of media…

Students' experiences of physical education (PE) are considered important for lifelong attitudes towards physical activity. Sex-related differences and the individualised tempo in anthropometric growth because of biological maturation lead to secondary school students within chronological age-ordered classes possessing vast differences in…

This meta-analysis examined the associations between teachers' language practices and children's language development from preschool to third grade. We screened 14,852 articles. A total of 119 articles from 104 distinct studies were analyzed, comprising 415 effect sizes across 13,572 teachers and 112,533 child participants. The result of the…

Over 5 million American children under the age of 18 years, a disproportionate number of whom are Black or Latino, have had a residential parent jailed or incarcerated. While a number of existing studies identify parental incarceration as a key risk factor for poor child and family outcomes, there is more limited information describing programs…

Having an imaginary companion (IC) is a fascinating example of children's imaginative and pretend play. However, there are inconsistencies in the reported prevalence of children's ICs. This study examined how culture may affect this prevalence. We conducted a meta-analysis to assess whether the culture, as well as age, assessment method, sex, and…

From an early age, most children choose to play with toys typed to their own gender. In order to identify variables that predict toy preference, we conducted a meta-analysis of observational studies of the free selection of toys by boys and girls aged between 1 and 8 years. From an initial pool of 1788 papers, 16 studies (787 boys and 813 girls)…

Rett syndrome (RTT) is a neurogenetic disorder in which a period of typical development is followed by loss of previously acquired skills. Once thought to occur exclusively in females, increasing numbers of male cases of RTT have been reported. This systematic review included 36 articles describing 57 cases of RTT in males. Mutations of the MECP2…

Child gender has been proved to affect toddlers'/children's language development in several studies, but its effect was not found to be stable across different ages or various aspects of language ability. The effect of gender on toddler's, children's and adolescents' language ability was examined in the present meta-analysis of ten Slovenian…

It has been argued that children who possess an advanced theory of mind (ToM) are viewed positively by their peers, but the empirical findings are mixed. This meta-analysis of 20 studies including 2,096 children (aged from 2 years, 8 months to 10 years) revealed a significant overall association (r = 0.19) indicating that children with higher ToM…

The aim of this article is to demonstrate how relational experiences with parents and preschool teachers provide children with a feeling of security that facilitates the development of competence in different domains. We first focus on the mechanisms regarding how secure attachments to parents serve as an important foundation for later…

During the past three decades, extensive literature has accumulated on the early years of life for children. Research findings unequivocally agree that these years are a critical period of intense learning for children which provides the foundation for later academic and social success. This review explores the literature on the complex…

"Interpersonal" rejection and "intergroup" exclusion in childhood reflect different, but complementary, aspects of child development. Interpersonal rejection focuses on individual differences in personality traits, such as wariness and being fearful, to explain bully-victim relationships. In contrast, intergroup exclusion focuses on how in-group…

Background: Research on resilience in the aftermath of potentially traumatic life events (PTE) is still evolving. For decades, researchers have documented resilience in children exposed to corrosive early environments, such as poverty or chronic maltreatment. Relatively more recently, the study of resilience has migrated to the investigation of…

The literature on clergy-perpetrated sexual abuse suggests that there are two modal populations of survivors: boys and adult women. We review what is known about trauma and post-traumatic stress disorder following sexual abuse and explore the different treatment needs for these two survivor groups. For children, clergy-perpetrated sexual abuse can…

This paper focuses upon the developmental role of rough and tumble (R&T) play with particular attention to the narratives that children use to underpin such activities. A review of the literature suggests that current early years research and practice pays scant attention to children's outdoor free play activities. A piece of original research is…
