As young as 3 years old, children rely on a mutual intentionality framework to confer group membership--that is, agreement between a joiner ("I want to be in your group") and group ("We want you to be in our group"). Here, we tested whether children apply this cognitive framework in the context of identity-based groups,…

On a daily basis, children make decisions about how to negotiate their physical environment. Sometimes they engage in physical tasks that involve risk, requiring them to judge the safety of how to negotiate the environment safely. Individual differences in children's age, sex, physical size, and personality may impact those decisions. We used…

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…

Background: Adverse childhood experiences (ACEs) have long been associated with attention-deficit/hyperactive disorder (ADHD) diagnoses in children; but the data used is now over 6 years old (from 2017 to 2018). Understanding the current landscape of their prevalence and association is needed to capture evolving social, environmental, and economic…

The development of executive function (EF) has been linked to various life outcomes, motivating intense research on the topic. While much of this research has focused on more thoroughly understanding age-related changes of the underlying neurocognitive mechanisms involved, recent theoretical and empirical works have stressed how the immediate…

Extensive research demonstrates the far-reaching impacts of early childhood development (ECD) interventions, including both pre-primary education (PPE) and in-home nurturing. At the same time, a limited understanding of inequalities in ECD exposure across groups of children in many countries poses a fundamental challenge to effective policymaking.…

Girls, more than boys, experience a decrease in the severity of autism symptoms during childhood. It is unclear, however, which specific autistic behaviors change more for girls than for boys. Trajectories of autism symptoms were evaluated using the Autism Diagnostic Observation Schedule-calibrated severity scores (ADOS-CSS). Change in the…

Australian children aged 6-9 years (N = 120, 71 females; data collected in 2021-2022) were tasked with remembering the locations of 1, 3, 5, and 7 targets hidden under 25 cups on different trials. In the critical test phase, children were provided with a limited number of tokens to allocate across trials, which they could use to mark target…

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…

In this longitudinal study, we investigated the factor structure and stability of early-life temperament in a German sample, using three measures developed within Rothbart's psychobiological approach. Temperament was measured using the Infant Behavior Questionnaire Revised (IBQ-R) at the ages of 6 and 12 months, the Early Childhood Behavior…

This study investigated the complex relationship between false-belief (FB) understanding, structural language and pragmatic communication in typically developing children. A total of 78 Finnish children, aged from 4 to 6 years, including an equal number of boys and girls, participated in this study. In the first instance, the study explored the…

Cognitive tasks are seldom evaluated on their ability to provide valid and reliable measurements of the construct they intend to measure. This scarcity of psychometric evaluations makes it challenging to evaluate replications of experimental effects and to relate performance in cognitive tasks to other constructs of interest. In developmental…

Purpose: With climate change education becoming more prevalent in schools around the globe, it is increasingly important that we understand parental perspectives on this topic. Children cross the boundaries between home and school culture every day, and their parents' attitudes, beliefs, and practices can influence their academic engagement in all…

Although we cannot see or touch time, across many cultures, we use spatial representations to think about this abstract concept. Spatial representations of time are thought to support temporal concepts that might otherwise be difficult to represent and reason about, such as the temporal component of episodic memory. One common form of spatially…

Background/purpose. This study aimed to explore various demographic and relational factors affecting adolescents, with a particular focus on their self-esteem. Materials/methods. This study employed a descriptive and correlational research design to gather quantifiable data and examine the relationship between parent-adolescent dynamics and…
