Children's understanding of the stability of gender over time has long been recognized as a hallmark of early childhood cognitive development. Prior research has argued that until roughly age 6, children do not understand that a person's gender identity remains consistent if the person undergoes a change in gendered behavior or appearance.…

Parenting style plays an important role in children's externalizing behaviors. Differences in physiological regulation among children may lead to variations in whether or to what extent parenting style influences them. The present study aimed to investigate the effect of parenting styles on young children's development of externalizing behaviors…

Emotion dysregulation is one of the challenges that children with autism spectrum disorder (ASD) and their families face. It is unclear whether emotion dysregulation plays a mediating role in the relationship between sensory processing patterns and problem behaviors among these children. This study examined the relations between emotion…

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…

The present study aimed to examine the effectiveness of a multi-component intervention on cooperative behaviors in children with autism spectrum disorder (ASD). In this study, three dyads comprising six boys aged between 4.5 and 7 years with ASD participated, following a randomized multiple baseline design. The participants were asked to construct…

This study used data from 435 teacher-child dyads in early childhood classrooms to examine the extent to which teachers' use of behavior specific praise (BSP) with children screened for elevated rates of externalizing behaviors was influenced by the intensity of child challenging behavior and gender. Observational assessments indicated that…

The present study sought to evaluate the reproducibility of prominent findings stated by Fehr et al. in their developmental resource allocation experiment "Egalitarianism in Young Children", published in 2008. The experiment involved children making decisions about distributing sweets between themselves and either an in-group or an…

Research Findings: Social constructivist theories have proposed that caregivers' perceptions of children as morally responsible agents are an important factor in children's moral development. However, there is substantial variance in caregivers' ascriptions of moral agency to young children. The present study examined caregiver social conformity…

Children's relationships with their peers have important associations with their behaviour. The current study examined children's friendships during the formative school years and hypotheses were made regarding associations between how well-liked children were by peers, the reciprocity of these friendships, and with whom friendships were made.…

The Chairs of Conflict Resolution (CoCR) is a process developed for training children to discuss their conflicts constructively so they experience win-win outcomes. The present study examines the discussion taking place during the use of CoCR with young children 4-6-years-old. The discussion between the two children proceeded in four phases: (a)…

What drives children to explore and learn when external rewards are uncertain or absent? Across three studies, we tested whether information gain itself acts as an internal reward and suffices to motivate children's actions. We measured 24-56-month-olds' persistence in a game where they had to search for an object (animal or toy), which they never…

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)…

While research on children's humour is growing, few investigations have focused on how children use humour in conflict interactions, and specifically in group early childhood settings. Using data extracts from a project that investigated children's naturally occurring conflict interactions in a multi-ethnic early childhood setting, we use…

Sometimes we should persist to succeed. But other times it might be wiser to give up on the task at hand and focus our energy on something new. Knowing whether a task is worth the effort potentially requires multiple capacities, including sensitivity to one's own likelihood to succeed on the current problem, the associated costs with continuing to…

The current study aims to clarify the temporal associations between maternal sensitivity and children's sleep problems across early childhood. This study comprised 942 Dutch mother-child dyads from the Generation R Study, a population-based prospective cohort study. Throughout early childhood, maternal sensitivity was observed in mother-child…
