Two studies examined the process and aftermath of coming to disbelieve in the myth of Santa Claus. In Study 1, 48 children ages 6-15 answered questions about how they discovered Santa was not real and how the discovery made them feel, and 44 of their parents shared their perspectives and how they promoted Santa. In Study 2, 383 adults reflected on…

This preregistered, longitudinal study examined how much adolescents value and integrate their parents' and peers' attitudes into their own attitudes from early to middle adolescence. Across three waves, participants (N = 172, 91 female, 11-16 years across three waves; 439 data points) decided whether to pay money to learn their parents' or peers'…

Friends are a vital source of social relations throughout the lifespan and across developmental stages. Our knowledge of how friendships develop over time, especially from childhood through adulthood, is limited. Furthermore, it is now recognized that this specific type of relationship influences health across the life course in unique ways. Using…

Children are developing alongside interactive technologies that can move, talk, and act like agents, but it is unclear if children's beliefs about the agency of these household technologies are similar to their beliefs about advanced, humanoid robots used in lab research. This study investigated 4-11-year-old children's (N = 127, M[subscript age]…

The goals of this study were to investigate (a) the dyadic relations of mothers' and children's perceptions of children's anxiety symptoms across development, (b) whether maternal perceptions of children's anxiety serve as a mediator of the association between maternal anxiety and child anxiety, and (c) whether sensitive/structured parenting…

Despite the potential benefits of children's confrontations of other children's racial biases--especially for targets of bias--little is known about how young children react upon observing instances of racial discrimination. In the present research, child participants completed a novel measure designed to test their reactions to another child's…

The present study examines perceptions of relationship quality as antecedents of best friendship dissolution. Participants included 230 students in Florida (United States; 54.3% girls; ages = 8-13; 39.6% European American, 27.0% Hispanic American, 21.7% African American, and 2.6% Asian American) and 496 students in Lithuania (49.0% girls; ages =…

Preschoolers who display extremely inhibited behavior are at risk for the development of anxiety disorders. However, behavioral inhibition (BI) is a multifaceted characteristic. Some children with BI are fearful when confronted by unfamiliar adults, peers, and objects; others are fearful when separated from their parents. In the present study, we…

Children develop expectations of caregivers' support-giving during early-life interactions. The present study examined whether caregivers' responsiveness would influence young children's expectations of caregivers' support-giving behavior and willingness under different situational stress levels. We manipulated the caregivers' responsiveness and…

Past research has demonstrated that both consequentialist motives (such as deterrence) and deontological motives (such as "just deserts") underlie children's and adults' punitive behavior. But what motives do we ascribe to others who pursue punishment? The present work explores this question by assessing which punitive motives children…

This longitudinal, quasi-experimental field study investigated affective forecasting as a moderator of positive intergroup contact effects among adolescents. We also examined a novel mediating mechanism that underlies this effect, namely accuracy of perceived outgroup willingness for intergroup contact. Three annual waves of survey data were used…

High achievers vary in terms of the constraints and difficulties they encounter on the road to success. The present study investigates whether and how children consider the constraints one overcomes in their beliefs and reasoning about academic achievement. Four- to nine-year-olds (N = 98, 57 girls, 41 boys) and their parents (N = 92, 80 females,…

We examined the development of children's positive and negative attitudes toward other-gender peers over 1 year, and explored the longitudinal social consequences of holding positive or negative attitudes on the beholder of these attitudes. Participants were 206 second graders (Mage = 7.18 yrs, SD = .56, 50% girls) and 206 fourth graders…

Black Lives Matter (BLM) has profoundly shifted public and political discourse about race in the United States and thus the broader sociopolitical landscape in which children learn about race and their own racial identities. A sample of Black, White, and Multiracial children (N = 100; M[subscript age] = 10.18 years old) were interviewed about…

A growing body of literature shows that adherence to some aspects of Western masculinity norms, including the suppression of emotional vulnerability, avoidance of seeking support from others, and exaggerated physical toughness, is associated with poorer psychological and social outcomes. While existing research suggests that parental gender…
