This meta-analysis aimed to investigate whether screen exposure is beneficial or detrimental for early language development. A total of 28 eligible studies were synthesized to examine the correlation between screen exposure (including screen time, educational programme viewing, co-viewing, and start age of screen exposure) and language development…

Effortful control, the ability to suppress a dominant response over a subdominant one, is a fundamental aspect of self-regulation. It has been observed that higher levels of parenting stress are associated with lower levels of effortful control in children. Perceived social support, an important factor in reducing parenting stress, may act as a…

Despite growing interest in placental epigenetics, the combined impact of prenatal stress and socioeconomic status on placental methylation is still largely understudied. We conducted a study to examine the associations of prenatal stress and socioeconomic factors (household income, Hollingshead socioeconomic index) with placental methylation.…

Childhood socioeconomic status (SES) is related to disparities in the development of both language and executive functioning (EF) skills. Emerging evidence suggests that language development may precede and provide necessary scaffolding for EF development in early childhood. The present preregistered study investigates how these skills co-develop…

In recent years, adolescent sleep problems have received increasing attention. Stressful life events have been found to be a risk factor for sleep problems, but little is known about the components that may explain or influence this association. To investigate this, the present study tested whether depressive symptoms mediated the association…

Previous studies have shown that demographic factors can influence parental mediation strategies during children's digital gameplay. However, little is known about maternal and paternal mediation in Iranian families. This study examined the relationship between maternal and paternal mediation (restrictive, active, viewing, technical, and…

Caregiver abstract talk during shared reading predicts preschool-age children's vocabulary development. However, previous research has focused on level of abstraction with less consideration of the style of extratextual talk. Here, we investigated the relation between these two dimensions of extratextual talk, and their contributions to variance…

Objective: The objective of this study is to assess the impact of COVID-19 on university students' academic performance. Participants: Our sample consisted of students 18 years old and above enrolled at least part-time during the Spring 2020 semester. Methods: This cross-sectional survey examined the individual, social, and economic impacts of…

Reading proficiency is important because it has life-long consequences and influences success in other academic areas. Many students with behavior problems are poor readers and many students with learning disabilities have more behavior problems than their typical peers. We conducted a correlational meta-analysis to examine the association between…

Background: Research finds center-based child care typically benefits children of low socio-economic status (SES) but few studies have examined if it also reduces inequalities in developmental disadvantage. Objective: I test if the length of time in center-based care between ages one and three years associates with child development scores at age…

The negative health effects of cigarette smoking during pregnancy (SDP) on the foetus are well known. Despite previous reports of poor cognitive performance in offspring exposed to SDP, few studies specifically consider language outcomes according to maternal smoking. In this study, we systematically review the literature to assess the…

In Early Childhood Education and Care (ECEC) programs, the quality of teacher-child interactions is regarded to be important for children's vocabulary development. However, prior studies on the relationships between teacher and child, as measured by the Classroom Assessment Scoring System (CLASS), and children's vocabulary skills are inconsistent.…

Multiple domains develop simultaneously and interact throughout infancy and early childhood. Although relationships between motor and language skills have been examined cross-sectionally during the first three years of life, little is known regarding the individual factors that influence the development of these domains as well as the relationship…

Despite a robust literature examining the association between sleep problems and cognitive abilities in childhood, little is known about this association in toddlerhood, a period of rapid cognitive development. The present study examined the association between various sleep problems, using actigraphy, and performance on a standardized test of…

The purpose of this non-experimental quantitative study was to investigate the relationship between learned helplessness and academic baseline levels among adult students who dropped out of high school and have returned to a high school equivalency program to prepare to take the GED examination. The study controlled for the variables of the age of…
