Parenting and children's temperament are important influences on language development. However, temperament may reflect prior parenting, and parenting effects may reflect genes common to parents and children. In 561 U.S. adoptees (57% male) and their birth and rearing parents (70% and 92% White, 13% and 4% African American, and 7% and 2% Latinx,…

Character strengths are an integral component of positive youth development that can promote flourishing. Developmental principles posit constructs become increasingly complex with age, yet this process has not been examined with character. Using a socioeconomically and ethnically diverse sample of 2,467 youth ages 9-19, bifactor models were…

Twin factor mixture modeling was used to identify temperament profiles while simultaneously estimating a latent factor model for each profile with a sample of 787 twin pairs (M[subscript age] = 7.4 years, SD = 0.84; 49% female; 88.3% Caucasian), using mother- and father-reported temperament. A four-profile, one-factor model fit the data well.…

This study examined the contribution of nonparental child-care services received during the preschool years to the development of social behavior between kindergarten and the end of elementary school with a birth cohort from Québec, Canada (N = 1,544). Mothers reported on the use of child-care services, while elementary school teachers rated…

Effortful control (EC), or the trait-like capacity to regulate dominant responses, has important implications for children's development. Although genetic factors and parenting likely influence EC, few studies have examined whether they interact to predict its development. This study examined whether the "DRD4" exon III variable number tandem…

In one of the first open diffusion experiments with young children, a tool-use task that afforded multiple methods to extract an enclosed reward and a child model habitually using one of these methods were introduced into different playgroups. Eighty-eight children, ranging in age from 2 years 8 months to 4 years 5 months, participated. Measures…

This study examined early observed parenting and child-care experiences in relation to functioning of the hypothalamic-pituitary-adrenocortical axis over the long term. Consistent with the attenuation hypothesis, individuals (n = 863) who experienced: (a) higher levels of maternal insensitivity and (b) more time in child-care centers in the first…

This study examined the additive and interactive effects of temperament and harsh and indulgent parenting on Chinese children's proactive and reactive aggression. Participants were 401 children (M [subscript age] = 9.29 years, 203 girls) and their parents who were recruited from 2 elementary schools in Shanghai, People's Republic of China. The…

This study charted the development of gendered personality qualities and activity interests from age 7 to age 19 in 364 first- and second-born siblings from 185 White, middle/working-class families, assessed links between time in gendered social contexts (with mother, father, female peers, and male peers) and gender development, and tested whether…

Two hypotheses--high self-esteem leads children to act on antisocial cognitions (disposition-activating hypothesis) and high self-esteem leads children to rationalize antisocial conduct (disposition-rationalizing hypothesis)--were investigated in two longitudinal studies. In Study 1 (N = 189; mean age = 11.1 years), antisocial behavior was…

Infant joint attention has been observed to be related to social-emotional outcomes in at-risk children. To address whether this relation is also evident in typically developing children, 52 children were tested at 12, 15, 24, and 30 months to examine associations between infant joint attention and social outcomes. Twelve-month initiating and…

Examined patterns of correlations among selected parental, contextual, and child characteristics accounting for variance in observed quality of parent-infant interaction and infant development with 15-month-olds and their families. Found that parental ego-resiliency and education, partner support, and infant social fearfulness explained…

The developmental trajectories of behavioral control and resiliency from early childhood to adolescence and their effects on early onset of substance use were examined. Behavioral control is the tendency to express or contain one's impulses and behaviors. Resiliency is the ability to adapt flexibly one's characteristic level of control in response…

Reports on a longitudinal study that provides a prospective view of children's personality functioning prior to their subsequent experiencing of divorce. Shows the behavior of boys as early as 11 years prior to parental separation or formal dissolution of marriage to be consistently affected by predivorce familial stress. (HOD)

Examined the reactions of 201 elementary school children to direct and indirect help and the moderating effects of grade, understanding of personality, and sex on children's reaction to aid. Results indicated that children high in the understanding of consistency of personality were more autonomous in the indirect than the direct help condition.…
