This article examines the impact of within-class age differences on educational outcomes, using students' birth months in Madrid's primary schools as a natural experiment. Employing a regression discontinuity design, we analyze third-grade students to investigate these age-related effects. Additionally, we explore whether early childhood education…

Research Findings: This study examined age-based developmental trajectories of four key number sense (NS) skills within an accelerated longitudinal design. Using data from 408 preschoolers, ages 45 to 68 months, linear and latent basis growth curves were evaluated. Results indicated growth across NS skills was best represented as nonlinear for all…

This study investigated direct and indirect pathways from listening comprehension (LC) to reading comprehension (RC) via fluent word reading (FWR) in grades 1-3, and path equivalence across these grades. LC's total effects predicting RC range from 0.45 to 0.59 in grades 1-3, a stronger relationship than found in previous studies. Overall, LC's…

Research Findings: This study aims to examine the latent profiles of parents' mediation and their predictors, as well as links between different profiles and children's problematic media use. A total of 1415 children aged 3-6 years (47.8% boys) and their paired parents were recruited in Shanghai, China and surveyed demographic information,…

We investigated performance levels on conducting continuous two-footed jumping of preschool children (4 years old) to high school students (16 years old) to clarify the developmental progression and sex differences in motor coordination and agility. In total, 450 children (boys: 227; girls: 223) participated in this study. We set 10 obstacles to…

This study examined the relationships between word reading and rapid automatized naming (RAN) for objects and letters in Arabic-speaking children with and without dyslexia to determine potential modulating effects of color on naming by comparing children's performance on color and black-white RAN plates. Participants were 114 Arabic-speaking third…

Background: Primary school teachers play an important role in furnishing children with basic knowledge about health literacy and awareness of COVID-19. This study was conducted to determine the levels of health literacy and COVID-19 awareness among preservice primary school teachers and the factors associated with this. Methods: The sample of this…

Research Findings: Self-regulation is an important determinant of children's developmental outcomes, but little research has explored its different facets simultaneously. This study aims to explore a sample of Chinese children's behavioral, cognitive and emotional self-regulation characteristics by examining their gender and age differences,…

Relatively few studies have directly examined children's memory of object-based spatial structure of room-sized environments. The current study investigated how children remember the spatial structure of a room, and the role of pictorial working memory (WM) and different testing perspectives in this process. In Experiment 1, 80 children aged 5 to…

Research Findings: This study investigated children's feelings about school and their adaptation to primary school after leaving kindergarten. Altogether, 28,334 Chinese children (ages 6-8 years) were sampled and surveyed online. The descriptive statistic, latent class analysis (LCA) approach, and logistic regression analysis indicated that: (1)…

Perceived life satisfaction during the period of childhood and adolescence can be considered a reliable measure of psychological and emotional growth of children and adolescents. The current study aimed to investigate age differences related to social support provided to students (by teachers, classmates, parents and close friends), and its…

Background: Previous research showed a significant association between mathematics and working memory (WM). However, evidence regarding the different effects of verbal and visuospatial WM on mathematical abilities was very limited. Aims: The current research aims to explore the relationship between verbal and visuospatial WM with mathematical…

Although more is known about how general parenting practices predict social-emotional strengths in children, less research has looked at parent involvement in education and children's social-emotional strengths. This study examined the extent to which parent involvement, specifically home-based involvement, parent-teacher trust, and home-school…

There is growing evidence that school starting age impacts children's likelihood of receiving special education services, but less is known about variations in this effect. Using a regression discontinuity design, I found that the youngest students in a kindergarten cohort are 40% more likely (p < 0.001) to be placed in special education than…

Multiple studies have shown that children conform to majorities in perceptual judgment tasks against their better knowledge. However, these studies report contradictory results about how conformity develops over age. Here, we study variation in conformity over the course of middle childhood: we examined potential informational and normative…
