Previous work has shown the robust nature of gender bias in both children and adults. However, much less attention has been paid toward understanding what factors shape these biases. The current preregistered study used parent surveys and child interviews to test whether parents' conversations with their children about and modeling of gender…

Many caregivers wonder when to talk to children about social inequality and racism, often expressing the belief that children do not pay attention to race or inequity. Here, across 5-9-year-old American children (n = 159, M[subscript age] = 7.44; 51.6% female, 47.2% male, 1.2% nonconforming or not provided; 59.1% White, 23.3% racial-ethnic…

The current study used meta-analysis to ask whether age differences, sex differences, and family size are linked to differences in parental treatment, as well as whether effect-sizes were moderated by the way parental differential treatment (PDT) was measured, who reported on the PDT, and the domain of PDT. Between August 2015 and November 2020,…

In early adolescence, levels of conscientiousness and agreeableness have been found to temporarily decrease, with levels of neuroticism increasing, indicating a dip in personality maturation. It is unknown whether these changes are related to the process of puberty, a major developmental milestone with numerous changes for children. Here, we first…

This study examined the relations between normative developmental changes of familism values and later internalizing and externalizing behaviors in Latinx adolescents from an emerging immigrant community. The sample included 547 Latinx adolescents (55.4% female; baseline M[subscript age] = 12.80; SD = 1.03) residing in the Southeastern United…

Intraindividual variability (IIV) in cognitive speed, or moment-to-moment changes in ability, is a developmental phenomenon indicative of neurological integrity that increases gradually across adulthood. Past research has shown that IIV negatively covaries with cognitive performance, in which higher IIV at one occasion is associated with poorer…

Sex is a significant social category, and adults derive information about it from both faces and bodies. Research indicates that young infants process sex category information in faces. However, no prior study has examined whether infants derive sex categories from bodies and match faces and bodies in terms of sex. In the current study,…

Do young children use information about gender and race to guide their prosocial gestures, and to what extent is children's selective prosociality related to other intergroup phenomena? Two studies tested 3- to 5-year-old children's allocation of resources to, social preferences for, and expectations about the behaviors of unfamiliar people who…

The present study explored cultural differences in parental beliefs about motor development across 2 Western cultures: Israel and the Netherlands. Can 2 cultural models be distinguished regarding infant motor development in Israel and the Netherlands or are parental beliefs about motor development similar across these cultures? Using a…

For the 5 million low-income Latino children in the United States who are disproportionately impacted by the numerous risk factors associated with poverty, it is essential to identify proximal protective factors that mitigate these risks and bolster the academic and social skills that are foundational to a successful transition into formal…

Disclosure, or revealing personal information to others, is important for the development and maintenance of close relationships (Jourard, 1971; Rotenberg, 1995). More recently within developmental psychology, however, the focus has been the study of adolescent disclosure to parents as a means of information management regarding their daily…

Ingroup preferences when deciding who to include in 2 distinct intergroup contexts, gender and school affiliation, were investigated. Children and adolescents, in the 4th (9-10 years) and 8th (13-14 years) grades, chose between including someone in their group who shared their group norm (moral or conventional) or who shared their group membership…

Children (N = 76; ages 5-10 years) participated in a study designed to examine perceptions of gender discrimination. Children were read scenarios in which a teacher determined outcomes for 2 students (1 boy and 1 girl). Contextual information (i.e., teacher's past behavior), the gender of the target of discrimination (i.e., student), and the…

The transition from high school to college is an important developmental milestone that holds the potential for personal growth and behavioral change.
