The present study examines the visual attention span deficit hypothesis in Chinese developmental dyslexia. Twenty-five Cantonese-speaking Chinese dyslexic children (DD group) were compared with 25 chronological-age-matched (CA) controls and another 25 reading-level-matched (RL) controls on their performance in visual attention span, reading, and…

Identifying and understanding the predictors of preliteracy skills can set the stage for success in a child's academic career. Recent literature has implicated social-emotional competence as a potential component in helping children learn preliteracy skills. To further understand the role of social-emotional competence in preliteracy, the…

High and stable levels of aggression and the presence of aggressive behaviour in multiple settings according to different informants are risk factors for later problems. However, these two factors have not been investigated in early childhood. The present study investigates trajectories of parent-reported child aggression from 1.5 up to 6 years of…

Inattentive-hyperactive and oppositional behavior have been hypothesized to be developmental precursors to conduct problems. We tested these hypotheses using a longitudinal sample of 6,466 offspring of women selected from nationally representative US households. Conduct problems across 8-13 years were robustly predicted by conduct problems at 4-7…

Background: Earlier studies of young people with Down's syndrome have investigated a relatively limited range of variables which may influence their academic attainment. The relative strength of such influences and how they may vary during the school career, has also been under-researched. Aims: The aim of the paper is to identify the contemporary…

Applying optimal stimulation theory, the present study explored the development of sustained attention as a dynamic process. It examined the interaction of modality and temperament over time in children and adults. Second-grade children and college-aged adults performed auditory and visual vigilance tasks. Using the Carey temperament…

Background: Using longitudinal data from the NICHD Study of Early Child Care and Youth Development, we examined behavior problems and social and academic outcomes from ages 9 through 12 in children classified into five trajectories of physical aggression, on the basis of maternal ratings obtained from 24 months through 9 years (N = 1195). Methods:…

Neonatal assessments should provide valid estimates of behavior and neurological status, reflect recovery from acute effects, predict subsequent outcome, and point to specific intervention strategies for any problems noted. The authors report relations among measures designed to evaluate early behavioral capabilities and dysfunctions in areas…
