Background: Longitudinal pediatric neuroimaging studies have demonstrated increasing volumes of white matter and regionally-specific inverted U shaped developmental trajectories of gray matter volumes during childhood and adolescence. Studies of monozygotic and dyzygotic twins during this developmental period allow exploration of genetic and…

This study tested a model of the association between maternal and child anxiety that views mother and child attachment beliefs and children's perceptions of maternal control as mediators of the association. The study was conducted with mothers and their children aged 6 to 17 (N = 88). Maternal anxiety was significantly associated with child…

Neuromaturation is the functional development of the central nervous system (CNS). It is by its very nature a dynamic process, a continuous interaction between the genome and first the intrauterine environment, then the extrauterine environment. Understanding neuromaturation and being able to measure it is fundamental to infant neurodevelopmental…

The purpose of this study was to measure school nurses' perceived self-efficacy in providing diabetes care and education to children and to identify factors that correlate with higher self-efficacy levels in the performance of these tasks.

The author examined age, gender, and ethnic differences in the self-perceptions of 112 low-income children who were assessed with the Pictorial Scale of Perceived Competence and Social Acceptance (PSPCSA) at Head Start and kindergarten. Children's self-ratings of competence were overly optimistic across the 4 subscales of the PSPCSA during the 2…

The authors investigated the effects of attention to novelty, fear-anxiety, and age on 3 measures of conduct problems. They found several main and interaction effects. The results indicated the presence of the hypothesized 3-way interaction for 2 dependent measures (i.e., conduct problem, socialized aggression); the 3rd dependent measure (i.e.,…

The authors measured memory for individual features (objects only or locations only) and the combination of those features (objects and locations) in 9-, 12-, and 21-year-old students with a "yes" or "no" recognition task. Analysis of recognition memory performance (d' scores) revealed that although age differences existed in memory for individual…

This study examined age-related differences in functional learning performance manifested among children, adolescents, and young adults placed in a two-cue ecology involving cues with direct relation and inverse relations with the criterion. On each trial, participants were instructed to consider the values taken by two cues, predict from these…

This study tested the association between mother's early age at first birth and various life outcomes for her children in later adolescence and early adulthood. Data were analyzed from the Rochester Youth Development Study, an ongoing panel study of adolescents enrolled in seventh or eighth grade in Rochester Public Schools in 1988 ("N"=729). Boys…

Objective: This study aimed to explore the relationship between perceived neighborhood social disorder and attitudes toward reporting child physical abuse. Method: Data from a national probabilistic sample (N = 9,759) were used. Responses about the perception of neighborhood social disorder, perceived frequency of child physical abuse in Spanish…

Regular physical activity participation throughout childhood provides benefits to physical (Malina, Bouchard, & Bar-Or, 2004), physiological (Andersen, Wedderkopp, Hansen, Cooper, & Froberg, 2003), and psychological health (Mutrie & Parfitt, 1998). In recognition of these benefits, guidelines have been published in the United States…

Despite the largely monolithic descriptions of Asian American students as high achieving model minorities, Asian Americans are a diverse group and their experiences are varied and complex. This article explores the ways that social class, ethnicity, generation, and gender shape the educational opportunities, experiences and achievement of Asian…

A sample of 283 Hispanic children with literacy performance at entrance to first grade below the median for their school district was studied as part of a larger research project on the predictors of grade retention in grade 1. Following retention decisions, 51 Hispanic students were retained in first grade. Low literacy skills, being young at…

The present study examined gender differences in the rate, type, and relevant variables underlying delinquent behavior among South Korean adolescents. Although female delinquency is increasing and becoming more violent in South Korea, the rate of delinquent behavior was found to be much lower among female than among male adolescents and female…

This study examined whether a comprehensive set of psychosocial factors was equally predictive of both adolescent vaginal intercourse and oral sex among 1,105 adolescents aged 12-16. Logistic regressions were used to examine the relationships between parental communication, religiosity, bonding to school, heavy drinking, sex expectancies,…
