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…

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…

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'…

The authors examined task-based (i.e., executive function), surveyed (i.e., effortful control), and physiological (i.e., resting cardiac respiratory sinus arrhythmia [RSA]) measures of child and maternal regulation as distinct moderators of longitudinal bidirectional links between child externalizing (EXT) behaviors and harsh parenting (HP) from 6…

The present study investigated whether distinct developmental patterns of externalizing behaviors (EBs: hyperactivity-impulsivity, noncompliance, physical aggression) based on parent reports were repeatedly and differentially associated with separate dimensions of internalizing problems such as general anxiety, separation anxiety, and depressive…

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…

Child temperament has long been viewed as a potential susceptibility factor in the link between parenting and child disruptive behavior (CDB). Specifically, the idea is that children with higher negative emotionality, surgency, and lower effortful control are more affected by their received parenting, but experimental evidence is scarce. Also,…

Parental burnout is a state that parents feel exhausted in their parental role. Although past research has examined concurrent correlates of parental burnout, the impacts of parental burnout on adolescent development over time remain largely unknown. The current study explored the indirect mechanisms linking mothers' parental burnout to…

The current article examines associations between preschool cognitive and behavioral skills and indicators of college enrollment in a sample (n = 379) of primarily Black and Hispanic youth growing up in low-income areas of Chicago. Although we found that most early cognitive and behavioral skills were only weakly or moderately related to later…

The second year of life is a time of formative developmental change as basic behavioral systems undergo rapid integration and expansion. This study examined the developmental trajectories of social-emotional (SoE) outcomes and the effects of infant sex and household chaos (HC) on the development of SoE outcomes across the second year of life. The…

The present study investigated prenatal and early postnatal risk factors associated with developmental patterns of disruptive behaviors (DBs; e.g., hyperactivity-impulsivity, noncompliance, physical aggression) from ages 1.5 to 5 years in a population birth cohort (N = 2,057; 50.7% boys). Six high-trajectory classes obtained by latent growth…

This study is a secondary data analysis that extends knowledge about the effects of the early childhood Family Check-Up (FCU) intervention to trajectories of general psychopathology problems (p factor) across early and middle childhood, and effects on adolescent psychopathology and polydrug use. The Early Steps Multisite study (ClinicalTrials.gov…

The architecture of sleep undergoes distinct changes during childhood and early adolescence. Slow wave sleep is involved in memory processing and may support active consolidation of newly encoded representations to support the formation of abstracted "gist" memories. Here, we examined sleep and overnight memory formation in German school…

This study examined relations of affinity for solitude with social-behavioral, academic, and psychological adjustment in Chinese children and adolescents. The participants included 3,417 students (1,714 boys) in fourth, sixth, and eighth grades (M[subscript ages] = 10, 12, and 14 years, respectively) in China. Data on affinity for solitude were…

Maternal anxiety and depression symptomatology are risk factors for the development of children's internalizing and externalizing behavior problems. However, it is still unclear whether chronic and transient symptoms relate differently to child behavior. The aim of this prospective longitudinal study (N = 193) was to investigate the associations…
