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…

Across all cultures, parents have intuitive ideas ("ethnotheories") of what undesirable child characteristics are as well as how to explain them. Yet there have been relatively few cross-cultural comparisons of parents' ethnotheories about the nature and causes of child misbehavior. 108 mothers of 5-year-old children from the United…

Girls, more than boys, experience a decrease in the severity of autism symptoms during childhood. It is unclear, however, which specific autistic behaviors change more for girls than for boys. Trajectories of autism symptoms were evaluated using the Autism Diagnostic Observation Schedule-calibrated severity scores (ADOS-CSS). Change in the…

Poor reading has been linked to negative outcomes on a wide range of emotional-behavioural dimensions in children. However, little is known about the time course of these associations. In this study we analyse data from a sample of Finnish children (N = 199; 106 boys) which included measures of reading fluency in grade 1 (age 7 or 8), and…

The current study investigates how internalizing and externalizing problems develop reciprocally across infancy to middle childhood, in relation to children's gender, cognitive functioning, socioeconomic status, and parental stress. The study also examines the impact of the developmental cascade of internalizing and externalizing problems on…

A double-blind randomized controlled trial of n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation or matching placebo during third trimester of pregnancy was conducted within the COPSAC[subscript 2010] mother-child cohort consisting of 736 women and their children. The objective was to determine if maternal n-3 LCPUFA pregnancy…

This study examined the protective roles of early prosocial behaviours (at age 4) on later internalizing and externalizing problems (at age 6) and to what extent emotion regulation skills (at age 5) mediated these longitudinal associations in children from Turkey. Participants were 293 Turkish preschool children (M[subscript age] = 49.01 months;…

This study examined early development of cool and hot self-regulation and how they were related to Chinese preschoolers' early achievement. A total of 951 children (448 girls) aged three to five in Hong Kong participated in this study. Children's self-regulation was assessed with a battery of five tasks tapping either cool or hot self-regulation;…

The Organisation for Economic Co-operation and Development (OECD) has reported that boys all over the world underperform their female peers at school. This trend creates problems for this generation of males and could also pose unforeseen consequences for the next generation. A review of journals, magazines, and other media outlets uncovered a…

Decision-making impairments during emerging adulthood confer risk for challenges in social and occupational roles and may increase the odds of developing health problems. Childhood maltreatment is related to maladaptation in cognitive and affective domains (e.g., executive functioning, emotion regulation) implicated in the development of…

The current 3-generation (N = 204 families), 3-year longitudinal study examined the intergenerational transmission of cultural socialization among Mexican-origin young mothers and their own mothers (i.e., children's grandmothers) and, in turn, whether young mothers' cultural socialization informed their children's developmental competencies (i.e.,…

In this article, we highlight Bronfenbrenner's bioecological approach to explore identity formation and the impact of dynamic interactions between the student and their environment in the development of self-concept, self-esteem, and self-efficacy. We examine the complex interactions between student identity and the systems of support that are…

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…

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…

The current study evaluated bidirectional associations between mother and father positive parenting and child effortful control. Data were drawn from 220 families when children were 3, 4, 5, and 6 years old. Parenting and effortful control were assessed when the child was 3, 4, and 5 years old. These variables were used to statistically predict…
