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,…

This study examined two subfactors of fundamental movement skills: locomotion skills and object-control skills. The direct and indirect effects of children's temperament on fundamental movement skills and the mediating effects of autonomy and self-regulation were examined. Participants included 278 pairs of 3- to 5-year-old children and their…

The role of early child care experiences on the development of the mother--child attachment relationship has been studied extensively. However, no prospective studies of early child care have addressed how these experiences might be reflected in the content of attachment representations during adolescence and beyond. The goal of this study was to…

Parental warmth and hostility are two key dimensions of parenting for child development, but the differential effects of these parenting dimensions on child prosocial and antisocial development has not been adequately investigated. The current study hypothesized that parental warmth would be uniquely related to child callous-unemotional traits and…

Diverse mechanisms account for the familial aggregation of certain personality traits and externalizing psychopathology. We explored the roles of positive and negative parenting as mediators of longitudinal associations between parents' maladaptive personality traits and their children's inattention/hyperactivity problems. We collected self,…

This systematic review investigates the effects of foreign language programmes in early childhood education and care (ECEC), which are increasingly popular. Foreign language ECEC centres familiarise very young children with a foreign language, and in general also expose them to the majority language. This review synthesises research on the effects…

Background: Although plausible links between language development and personality have been suggested, longitudinal studies of these associations into adulthood have not been conducted. Aim: To investigate whether children's age at attaining language milestones is associated with later adult personality. Methods: Mothers' of 8,400 children from…

Background: Evocative gene-environment correlation (rGE) describes a process through which children's heritable characteristics influence their rearing environments. The current study examined if heritable influences on parenting and children's behavioral outcomes operate through child negative emotionality. Method: Using data from the Early…

This developmental neuroscience study examined the electrophysiological responses (EEG and ERPs) associated with perspective taking and empathic concern in preschool children, as well as their relation to parental empathy dispositions and children's own prosocial behavior. Consistent with a body of previous studies using stimuli depicting somatic…

We compared the structure and the content of mothers' and fathers' infant-directed speech as a function of infant birth order. Seven first-born and four second-born infants were video-recorded during their natural dyadic interactions with their mothers and fathers at home from the second to the sixth month after birth at 15-day intervals.…

Children's development is fostered by both high quality Early Childhood Education and Care (ECEC) settings and high quality home learning environments. As we know little about the interrelations between these two environments, we examine whether the child's attendance in a high quality ECEC arrangement relates to the quality of her home learning…

Understanding the role of negative emotionality in the development of executive functioning (EF) and language skills can help identify developmental windows that may provide promising opportunities for intervention. In addition, because EF and language skills are, in part, genetically influenced, intergenerational transmission patterns are…

The present study examined teacher sensitivity as a potential moderator of the relationship between children's temperament in infancy and their social development in first grade. Using data from the Study of Early Child Care and Youth Development (NICHD SECCYD), we found that first grade teachers who were sensitive and responsive to students'…

The current study examined the heterogeneity in the development of school-based prosocial behavior from Grades 1 to 12 and the role of multiple early childhood antecedents in predicting heterogeneous developmental trajectories of prosocial behavior in a sample of 784 children facing early risks and vulnerabilities (predominantly from low-income…

Harsh environments are known to predict deficits in children's cognitive abilities. Life history theory approaches challenge this interpretation, proposing stressed children's cognition becomes specialized to solve problems in fitness-enhancing ways. The goal of this study was to examine associations between early environmental harshness and…
