Temperament and externalizing problems are closely linked, but research on how they codevelop across adolescence remains sparse and equivocal. Reinforcement sensitivity theory (RST) provides a useful framework for understanding temperament and externalizing problems associations. During adolescence, oppositional problems are posited to be linked…

Can well-documented gender differences in evaluations of prosocial versus antisocial actions found in childhood and adulthood be traced to sex differences in basic sociomoral preferences in infancy? We provide an answer to this question by meta-analyzing sex differences in preference for prosocial over antisocial agents in a set of 53 samples of…

Machiavellianism is an antisocial interpersonal style involving the use of manipulative, deceptive, and coercive behaviors in the pursuit of self-interest. Although widely studied as a "dark" personality trait in adults, relatively little is known about the developmental correlates of Machiavellian tendencies earlier in life. The present…

Early attention bias to threat-related negative emotions may lead children to overestimate dangers in social situations. This study examined its emergence and how it might develop in tandem with a known predictor namely temperamental shyness for toddlers' fear of strangers in 168 Chinese toddlers. Measurable individual differences in such…

Children who show elevated levels of indirect aggression (IA) from childhood to adolescence are at increased risks of experiencing detrimental outcomes. Some studies suggest that psychopathic traits could act as a predisposing vulnerability in the development of IA, but the contributions of all three dimensions of psychopathic traits in explaining…

Young children robustly distinguish between moral norms and conventional norms (Smetana, 1984; Yucel et al., 2020). In existing research, norms about the fair distribution of resources are by definition considered part of the moral domain; they are not distinguished from other moral norms such as those involving physical harm. Yet an understanding…

Most cooperative interactions involve interpersonal trust and the expectation of mutual reciprocation. Thus, understanding when and how humans acquire interpersonal trust can help unveil the origins and development of children's cooperative behavior. Here, we investigated whether prior sociomoral information about trading partners modulates the…

Prior studies have indicated that prosocial behavior might be a protective factor for developing internalizing and externalizing behavioral problems. However, little research has been conducted on within-person changes of prosocial behavior and behavioral problems over time. With random-intercept cross-lagged panel models (RI-CLPMs), the current…

Young children from a very early age not only prefer those who help others but also those who engage in altruistic helping. This study aims to test how children assess helping when the goal of the helping behavior is immoral. We argue that younger children consider only the helping versus hindering behavior, but older children distinguish their…

There is a well-documented interdependency between destructive interparental conflict (IPC) and parenting difficulties (i.e., spillover effect), yet little is known about the mechanisms that "carry" spillover between IPC and parenting. Guided by a cascade model framework, the current study used a longitudinal, multimethod,…

The goal of the current study was to investigate whether children's social information processing (SIP) predicts their conversations with peers, including both their remarks to peers and peers' remarks to them. When children (N = 156; 55% male; United States; Representation by Race: 60% African American, 18% Mixed race, 15% European American, 7%…

Developmental delays in cognitive flexibility early in elementary school can potentially increase vulnerability for subsequent externalizing and internalizing psychopathology. The first goal of the current study was to identify latent subgroups of children characterized by different developmental trajectories of cognitive flexibility throughout…

Children make choices between generosity and greed every day. Often they must also choose between confession or denial of antisocial acts like greed, thereby displaying either honesty or hypocrisy. Such choices pose cognitive challenges that, in theory, might reflect children's developing social-cognitions and affect their daily social lives and…

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…

This work refined the complex associations between aggression (aggressive behavior and victimization) and school functioning in terms of school liking, interest, achievement, and social class climate. First, using longitudinal multilevel structural equation modeling, it was shown that aggressive behavior and victimization preceded lower school…
