Data from 83,423 parent reports of temperament (surgency, negative affectivity, and regulatory capacity) in infants, toddlers, and children from 341 samples gathered in 59 countries were used to investigate the relations among culture, gender, and temperament. Between-nation differences in temperament were larger than those obtained in similar…

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…

This longitudinal study of Australian families (n = 1,884, from age 6-12) examined how fathers' and mothers' quantitative involvement (time spent on childcare) and qualitative involvement (specific parenting behaviors) relate to children's emotional adjustment development. We used dynamic structural equation modeling to disentangle stable…

Numerous event-related potential (ERP) studies have examined adults' neural responses to child emotional expressions to understand the neurobiological mechanisms contributing to caregiving. It is unclear, however, whether one emotion evokes an enhanced response across components, and whether this pattern differs based on parent status or other…

Little is known about the naturalistic development of mindfulness in adolescence and how it relates to changes in emotional well-being. The current longitudinal study examined the development of one dimension of mindfulness, nonreactivity to difficult inner experience (or in more colloquial terms, being able to notice, but "take a step…

This study tested child characteristics (temperamental executive control and negative reactivity) and maternal characteristics (parenting behaviors and maternal depressive symptoms) as predictors of a mother's emotion-related socialization behaviors (ERSBs). Further, parenting behaviors and ERSBs were examined as predictors of children's emotion…

This study examines interactions of heritable influences, prenatal substance use, and postnatal parental warmth and hostility on the development of conduct problems in middle childhood for boys and girls. Participants are 561 linked families, collected in 2 cohorts, including birth parents, adoptive parents, and adopted children. Heritable…

Compassion is known to predict prosocial behavior and moral judgments related to harm. Despite the centrality of compassion to social life, factors predicting adulthood compassion are largely unknown. We examined whether qualities of parent-child-relationship, namely, emotional warmth and acceptance, predict offspring compassion decades later in…

The current study examined the relations between individual differences in attention to emotion faces and temperamental negative affect across the first 2 years of life. Infant studies have noted a normative pattern of preferential attention to salient cues, particularly angry faces. A parallel literature suggests that elevated attention bias to…

The primary purpose of this study was to examine whether social relationship factors are associated with trajectories of depressive symptoms from adolescence into emerging adulthood. Specifically, adolescent-parent communication with mothers and fathers, peer support, and sibling warmth and hostility were examined in relation to depressive…

The developmental science literature is riven with respect to (a) parental similar versus different treatment of siblings and (b) sibling similarities and differences. Most methodologies in the field are flawed or confounded. To address these issues, this study employed a within-family longitudinal design to examine developmental processes of…

Given that maternal support promotes healthy social and emotional development in early childhood, it is important to understand the predictors of such support, especially during emotional challenges. In this study, mothers' dispositional distress reactivity (i.e., the tendency toward experiencing distress in response to children's negative…

General well-being is known to deteriorate sharply at the end of life. However, it is an open question how rates of terminal change differ across affective and evaluative facets of well-being and if individual difference correlates operate in facet-specific ways. We examined how discrete affective states (happy, angry, fearful, sad) and…

Research on family socialization of positive emotion has primarily focused on the infant and toddler stages of development, and relied on observations of parent-child interactions in highly structured laboratory environments. Little is known about how children's spontaneous expressions of positive emotion are maintained in the uncontrolled…

This 4-year study examined longitudinal interplays between adolescents' and mothers' self-reported empathic concern (EC) and perspective taking (PT). We investigated (a) whether adolescents' EC predicted rank-order change in their PT over time, or vice versa; (b) whether mothers' empathy predicted relative increases in adolescents' empathy; (c)…
