While a wealth of research evidence has highlighted the significant impact of prosocial modeling on shaping children's sharing behavior, the mechanism underlying this effect remains less understood. Here we consider the goal contagion account whereby children recognize the prosocial "goal" of others' actions and these goals are…

Attachment theory proposes that young children's experiences with their caregivers has a tremendous influence on how children navigate their social relationships. By the end of early childhood, intergroup contexts play an important role in their social life and children build strong ties to their ingroups. Although both domains relate to the same…

Cultural comparisons suggest that an understanding of other minds may develop sooner in independent versus interdependent settings, and vice versa for inhibitory control. From a western lens, this pattern might be considered paradoxical, since there is a robust positive relationship between theory of mind (ToM) and inhibitory control in western…

Many previous studies indicate that children are highly sensitive to the immoral behavior of others, preferring prosocial over antisocial characters. Accordingly, children avoid transgressors from a very early age. A special kind of transgressor is the moral hypocrite, who not only acts immorally but also acts in contrast to what they preach.…

Reciprocity is a cornerstone of human cooperation, motivating individuals to assist each other at a personal cost, resulting in mutual long-term benefits. However, reciprocity can conflict with honesty norms, such as when returning favors to previous benefactors requires individuals to act dishonestly. The resulting moral dilemmas are difficult to…

Gender nonconforming (GN) children are at higher risk of experiencing bullying and social exclusion than are gender conforming (GC) children. Nonetheless, very little is known about the socio-cognitive mechanisms underlying children's bias against GN peers. The present study was the first to examine children's dehumanization of GN peers…

Numerous studies have documented children's understanding of fairness through their ability to rectify inequities when distributing resources to others. Understanding fairness, however, involves more than just applying norms of equity when distributing resources. Children must also navigate situations in which resources are collected from them for…

Three preregistered studies examined whether 5-year-old children cheat consistently or remain honest across multiple math tests. We observed high consistency in both honesty and cheating. All children who cheated on the first test continued cheating on subsequent tests, with shorter cheating latencies over time. In contrast, 77% of initially…

Shyness is typically associated with avoidant social behavior and restricted affect in new social situations. However, we know considerably less about how one child's shyness influences another child's behavior and affect in new social situations. Children's shyness was parent-reported when children were age 3 (N = 105, 52 girls, M[subscript age]…

Children's sharing behavior is profoundly shaped by social norms within their society, and they can learn these norms by directly observing how most others share in their immediate environment. Here we systematically investigated the impact of majority influence on the sharing behavior of young Chinese children through three studies (N = 336, 168…

Inhibition (a temperamental profile characterized by elevated levels of avoidance behaviors) is associated with increased likelihood for developing anxiety and depression, whereas exuberance (a temperamental profile characterized by elevated levels of approach behaviors) is associated with increased likelihood for developing externalizing…

During childhood, the ability to limit problem behaviors (i.e., externalizing) and the capacity for cognitive regulation (i.e., executive function) are often understood to develop in tandem, and together constitute two major components of self-regulation research. The current study examines bi-directional relations between behavioral problems and…

This study compared parenting across four non-Western cultures to test cross-cultural commonality and specificity principles in three aspects: measurement properties, parenting normativeness, and their associations with child outcomes. Both mothers and fathers (N = 1509 dyads) with preschool-aged children (M = 5.00 years; 48% girls) from urban…

This study examined whether grandparental support is a protective factor for children's socio-emotional development in the context of adversity. Using longitudinal data from the Millennium Cohort Study, we investigated the effects of grandparental support across development in children with and without adverse childhood experiences (ACEs).…

Cheating emerges early in development and has significant moral development implications. This research investigated whether cheating in 5- to 6-year-olds reflects strategic decision-making or impulsivity. Through four preregistered studies, we systematically manipulated adult presence and observability across multiple conditions using a…
