Background: Attention-deficit/hyperactivity disorder (ADHD) symptoms and mathematics ability are associated, but little is known about the genetic and environmental influences underlying this association. Methods: Data came from more than 6,000 twelve-year-old twin pairs from the UK population-representative Twins Early Development Study. Parents…

The main aim of the study was to explore the ability of a brief developmental assessment to predict teacher-rated learning and attentional and behavioural skills in the first grade of school at both the group and individual levels. A sample of 394 children (181 males, 213 females) aged 4 years were followed to the age of 6 years, and 283 of the…

The objectives of this study were to establish the different developmental trajectories of hyperactive-impulsive behaviors on the basis of both mother and father ratings at 19, 32, 50, and 63 months, and to examine the predictive validity of these trajectories with respect to later hyperactive-impulsive behaviors, as rated by teachers in the first…

Critiques the current concept of attention deficit hyperactivity disorder (ADHD) as it applies to primary school boys and girls. The article defines ADHD, presents a model of developmental contextualization, and shows ways in which theory can overcome limitations in current conceptualizations of ADHD and guide future pedagogy and research.

This article re-evaluates the concept of "difficult temperament," documenting the difficulty of differentiating normal difficult behavior from difficult temperament, and difficult temperament from diagnosable psychiatric disorder. Researchers and clinicians acknowledge that childhood aggression is occurring with greater frequency and at younger…

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…

Places the limited knowledge of the psychological problems of American Indian and Alaska Native children in context of general child psychiatric epidemiology, using the taxonomy of the American Psychiatric Association's third "Diagnostic and Statistical Manual." Available from: White Cloud Center, Gaines Hall UOHSC, 840 Southwest Gaines…

Negative emotionality and poor attention may combine or interact as risk factors in development. Negative emotionality is considered a challenge for self-regulation, whereas good attention is a potential means of self-regulation. In the current study, composites of 1- and 2-year maternal ratings of negative emotionality and global ratings of…
