We examined behavior problems in 80 adolescents (39 male; mean age = 15.74 years) adopted in early childhood by Canadians from globally depriving Romanian institutions. Overall, rates of clinically significant behavior problems were comparable to rates found in younger postinstitutionalized adopted children. The association between duration of…

Family socioeconomic status (SES) and the quality of maternal behavior are among the few identified predictors of child executive functioning (EF), and they have often been found to have interactive rather than additive effects on other domains of child functioning. The purpose of this study was to explore their interactive effects in the…

Biological kinds undergo a variety of changes during their life span, and these changes vary in degree by organism. Understanding that an organism, such as a caterpillar, maintains category identity over its life span despite dramatic changes is a key concept in biological reasoning. At present, we know little about the developmental trajectory of…

In accord with the now prevailing ecological view that both parent and child play an active role in shaping their interactions, the present study assessed the number of bids by parents and children for social engagement, compliance, and emotion regulation, and the quality of each partner's responsiveness to these bids, in a sample of mothers…

We investigated longitudinally the co-constructed narratives of 31 mother-child dyads collected when the children were 3-, 4-, and 5-years old, examining the dual development of child conversational and narrative discourse skills and the impact of maternal verbal assistance. Linear mixed-model analysis revealed that children's developmental…

Children of ages 3-5 ("N" = 62) were assessed by using standard theory-of-mind tasks and unusual belief tasks related to false information and beliefs endorsing violations of moral (welfare and fairness) and social conventional (school rules) domains. Younger children (under 5 years) did not accurately attribute unusual factual beliefs…

This study investigated trajectories of time spent in structured activities from middle childhood to early adolescence by using data from the National Institute of Child Health & Human Development (NICHD) Study of Early Child Care. We used latent class growth analyses and identified five trajectories (stable low, increasing high, decreasing low,…

The present study compared 6- to 9-year-old children's reports of their decisions to express anger, sadness, and physical pain; methods of controlling and communicating felt emotion; and reasons for doing so in response to hypothetical situations across three groups: old-city India (n = 60), suburban India (n = 60), and suburban United States (n =…

Achieving consensus on the definition and measurement of social competence (SC) for preschool children has proven difficult in the developmental sciences. We tested a hierarchical model in which SC is assumed to be a second-order latent variable by using longitudinal data (N = 345). We also tested the degree to which peer SC at Time 1 predicted…

Four experiments were conducted with Japanese children and adult participants to assess their awareness of the effectiveness of biological and psychological treatments for psychogenic bodily reactions. Study 1 had 116 participants, composed of 4-year-olds (17), 5-year-olds (20), 7-year-olds (24), 10-year-olds (20), and college students (35). The…

Internal state language is a unique indicator of children's social understanding. In the current study, the role of context and type of internal state language was investigated. Mother-child internal state discourse in 32 middle-class Canadian families (child M age = 46.4 months) was examined across four contexts: (1) a reflective picture task,…

This study described the relations among the amount of child-directed versus adult-directed television exposure at ages 1 and 4 with cognitive outcomes at age 4. Sixty parents completed 24-hour television diaries when their children were 1 and 4 years of age. At age 4, their children also completed a series of cognitive measures and parents…

This study examines whether disagreeable youth are distinct from aggressive youth, victimized youth, and withdrawn youth. Young adolescents (120 girls and 104 boys, M = 13.59 years old) completed personality and adjustment inventories. Aggression, withdrawal, and victimization scores were derived from peer nominations (N = 807). Cluster analyses…

The present study focused on the role of cognitive, emotional, and interpersonal factors in predicting defending of bullied peer. Specifically, the degree to which peer status moderates the effects of emotional and cognitive factors on defending behavior was tested. The sample included 489 students (257 girls) from grades 4 (mean age, 10.6 years)…

This study examined early elementary school children's trajectories of peer victimization with a sample of 218 boys and girls. Peer victimization was assessed (via peer report) in kindergarten and first, second, and fifth grades. Hierarchical linear modeling (HLM) was used to examine multiple types of relationships (mother-child, student-teacher,…
