Socio-emotional school behavior and learning are both fundamental aspects of children's development influenced by cognitive control processes named Executive Functions (EF). Yet, research on school-age children has often focused on the relationship between EF and learning skills overlooking that of EF and school behavior, which has usually been…

Social exclusion, a pervasive and impactful phenomenon particularly prominent during preadolescence, has traditionally been construed through a moral deficiency lens. This study departs from prevailing research trends, casting a novel light on the phenomenon in the context of normative moral development. It elucidates the role of social exclusion…

The second year of life is a time of formative developmental change as basic behavioral systems undergo rapid integration and expansion. This study examined the developmental trajectories of social-emotional (SoE) outcomes and the effects of infant sex and household chaos (HC) on the development of SoE outcomes across the second year of life. The…

This study investigated the prevalence, and the developmental, behavior and emotional outcomes of 675 preschoolers with ASD with or without a history of regression, who participated in the Study to Explore Early Development (SEED). The SEED project is a cross-sectional case-control study that collected data between 2007 and 2011. Children's…

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…

This study aims to identify early childhood sociability trajectories and examine their longitudinal associations with behavior problems. Using a population-based data set presented by the Panel Study on Korean Children, sociability trajectories from age 2 to age 4 were identified by latent class growth analysis. Associations between sociability…

Understanding childhood socialization across multiple world cultures is important for developing comprehensive and generalizable theories of developmental psychology. Studies suggest that Latin American children show markedly high levels of prosocial behavior. In this article, we theorize that this hyper-prosociality is supported by a particular…

Preschool teachers' perceptions about relationships with students (teacher-child relationships [TCRs]) predict children's subsequent social competence (SC) and academic progress. Why this is so remains unclear. Do TCRs shape children's development, or do child attributes influence both TCRs and subsequent development? Relations between TCRs and…

Some parents experience concerns relating to their child's development and seek clinical assessments for their child's behaviour. We sought to understand the concerns that led parents to seek a general clinical assessment where some children were diagnosed with autism spectrum disorder. We conducted a systematic review to identify the types of…

We assessed the psychometric properties of the Social Behavior Questionnaire (SBQ), a 30-item questionnaire evaluating social (e.g., disruptive behaviors, bullying) and emotional problems (e.g., anxiety, depression) among children aged 3.5-12 years. Children (n = 1,950, 50.21% boys) were drawn from the Quebec Longitudinal Study of Child…

Traditional values in many cultures prioritize a deep respect for the environment and a recognition of the interdependence between humans and the natural world. They can help to broaden children's thinking about their choices, inform their decision-making, and help ensure children develop a closer connection with nature and pursue sustainable…

Social rejection is an undesirable phenomenon with serious present and future implications for children who experience it. Growing rates of social rejection and bullying in elementary-school children, especially on social networks, have been examined mostly from a pathological perspective focused on the rejected child or rejecting group. This…

A critical skill of childhood is learning social norms. We examine whether the generic pronouns "you" and "we," which frame information as applying to people in general rather than to a specific individual, facilitate this process. In one pre-registered experiment conducted online between 2020 and 2021, children 4- to…

A growing interest has been given to examining the heterogeneity of children's health to provide for their particular needs. This study examined subgroups of elementary school children's social, emotional, and behavioral functioning (SEB) using teacher ratings of children with the Behavioral and Emotional Screening System. A Latent Profile…

In early childhood, young children frequently engage in object-oriented play. According to cultural-historical activity theory, object-oriented play provides children with opportunities to learn about the characteristics and cultural applications of objects and materials. These characteristics are referred to as rules or affordances of objects and…
