A foundational mechanism underlying human cooperation is reciprocity. In the context of repeated interactions with others, it is not always clear the degree to which in-kind responses reflect responsiveness to partners' prior behaviors ("reactive" responses), an interest unrelated to the partner ("nonreactive" responses), or…

Children show less positivity toward gender-nonconforming (GN) than gender-conforming (GC) peers. Yet, little is known about children's reasoning about peers of varying gender expressions, including age-, gender-, and culture-related influences. We investigated how children aged 4- to 5- and 8- to 9-years-old in Hong Kong and Canada (N = 678)…

Research Findings: Parental supervision, parental risk perception, and parental risk attitudes constitute an important parenting environment for the development of young children. To examine the mechanisms of Chinese parenting environment on young children's risk-taking behaviors, this study first established a four-factor model and surveyed 497…

Mangroves provide vital ecosystem services like storm surge protection and carbon sequestration, but their coverage is rapidly declining. This study evaluates an environmental education program in the Dominican Republic, targeting children's attitudes, knowledge, behaviors, and willingness to pay for conservation. The program boosted attitudes,…

Objective: Physical activity (PA) is essential to promote both optimal physical and emotional health in preschool children. Hence, well-founded PA guidelines are essential. 24-hour Movement Guidelines (which include PA, recreational screen time and sleep) have been established. Thus, this study aimed to explore preschool-aged children's adherence…

Parents' cultural beliefs are associated with their children's socialization and development. Researchers have examined these associations through the lens of parents' ethnotheories, which refer to parents' implicit beliefs about children's developmentally appropriate behavior. In contrast to prior work focused on parents' ethnotheories of…

The purpose of this study was to examine the play skills of children with typical development and those with speech and language disorders (SLD) based on gender, the presence of siblings, and parents' education levels. There were 270 children included in the study's sample. In the study, 'The Play Behaviour Scale' was used. Reticent behaviour…

Research Findings: Empathy plays an important role in children's early social-emotional development. However, there are not many instruments available for measuring the different aspects/levels of empathy in preschool children. Moreover, few studies examined the validity of the existing measures for empathy in Chinese children. The present study…

Background: The longitudinal impact of fetal growth on attention problems in males and females is unclear. This study aims to evaluate the impact of fetal growth assessed by neonatal anthropometry throughout childhood and adolescence in males and females separately. Methods: We compared neonatal anthropometry (birth weight (BW), head circumference…

In order to comfort others, children need to exhibit Theory of Mind (ToM) skills. The goal of the present study was to investigate the role of ToM in association with children's spontaneous comforting behaviour in a laboratory task. Forty-seven children between 26 and 57 months of age completed three ToM tasks: diverse desires, diverse beliefs and…

Research Findings: Prosocial behavior in early childhood can be assessed by various informants and methodologies, but the information each provides may differ in meaningful ways. The present study measured and compared young children's (N = 486; age: M = 48.51 months, SD = 8.22) prosocial behavior based on parent reports, teacher reports, and…

Gender-typical play is observed throughout childhood for non-autistic children. However, there has been limited research into the gender typicality of autistic children's play compared to that of non-autistic children. In a longitudinal population-based cohort, we compared gendered play behaviours in autistic and non-autistic children using…

Physical abuse is one subtype of child abuse and it has been a worldwide public health issue for its detrimental effects on child development, profiles, predictors, and its relation with behavior problems need further exploration, particularly in Chinese children. This study attempts to explore profiles and predictors of physical abuse and to…

The associations of children's play behaviour to their emotional regulation, executive functioning were examined in this study. Teachers rated children's play behaviour, emotional regulation and executive functioning. The study sample comprised 127 (Mage in months = 60.685, SD = 9.563; 64 girls) Turkish children who continued formal education in…

The twofold aim of the present study was to examine the relationship between toddlers' physical and social spontaneity, as well as to investigate the interaction effects of gender, geographical background, and mother's occupational status on preschoolers' playfulness. Participants were 650 preschool children (353 boys, 297 girls), attending…
