Background: Brain activation differences between 12 control and 12 attention deficit hyperactivity disorder (ADHD) children (9- to 12-year-olds) were examined on two cognitive tasks during functional magnetic resonance imaging (fMRI). Method: Visual selective attention was measured with the visual search of a conjunction target (red triangle) in a…

Background: The objective of this study is to identify intact and deficient cognitive processes in children with attention deficit hyperactivity disorder (ADHD) and children with high functioning autism (HFA). Method: Three rigorously diagnosed groups of children aged between 6 and 12 years (54 ADHD, 41 HFA, and 41 normal controls) were tested on…

Attention deficit/hyperactivity disorder (ADHD) is a behavioral disorder characterized by inattention, impulsivity, and hyperactivity. The presence of ADHD is associated with behavioral and academic difficulties within a classroom setting. With a prevalence rate of 3% to 5%, teachers will undoubtedly come in contact with a student with ADHD at one…

Possessing high intellectual ability is no guarantee of academic success. In fact, the relevant literature often reports problems of delays in academic progress, as well as hyperactivity and attention problems in students of high ability. It is therefore relevant to design programs which help toward attainment of academic success. In this paper we…

Based on the reliable findings that children with attention deficit hyperactivity disorder (ADHD) have both attentional and academic difficulties, it is assumed that the attentional deficit contributes to the academic problems. In this article, existing support for a link between the attentional and academic difficulties experienced by children…

This paper provides an overview of selective research on autism. Autism forms part of a spectrum of related developmental disorders that vary in severity. Both their prevalence and severity argue for concerted efforts aimed at improving our understanding and treatment of the many individuals affected. We begin by outlining an important discovery…

The primary purpose of this study was to test two hypotheses proposed by Bracken and McCallum (1998), authors of the Universal Nonverbal Intelligence Test (UNIT), as to how children diagnosed with ADHD would perform on the UNIT. Twenty-nine students between the ages of 5 and 17 years were administered the extended battery of the UNIT twice, with…

Objective: According to the American Psychiatric Association, 3% to 7% of the school-age population has ADHD and many children continue to display significant symptoms throughout adolescences and adulthood. Relative to the childhood literature, less is known about ADHD in adults, especially college students with ADHD. The principle purpose of this…

Objective: Increasing numbers of adults are seeking treatment for ADHD. Pharmacotherapy is well established as the first line treatment for adult ADHD, although medications alone may be insufficient treatment for the myriad problems experienced by these patients. Few studies have examined the clinical outcomes of a combination of pharmacotherapy…

Objective: This study examines whether the Child Behavior Checklist (CBCL) can be used as an accurate psychiatric screening tool for children in community mental health settings. Method: Associations, logistic regression models, and receiver operating characteristic (ROC) analysis were used to test the predictive relationship between the CBCL and…

Objective: Behavior disorders are more prevalent among boys than girls, but the etiology of this difference is unclear. Studies have not tested for sex bias in ratings as a contributing factor to the differential sex prevalence rates. However, there are several studies showing "negative halo effects" in ratings of boys (i.e., the presence of one…

The Department of Education in the Australian state of Queensland promotes inclusiveness and states a commitment to all students achieving to their full potential ("Inclusive Learning", 2004, p. 17). Paradoxically, comprehensive review of Queensland Government education department policy indicates the vision of inclusive education is…

This article presents an overview of some methods and results from our continuing studies of genetic and environmental influences on dyslexia, and on individual differences across the normal range that have been conducted over the past 25 years in the Colorado Learning Disabilities Research Center (CLDRC) and in related projects. CLDRC…

Children with attention deficit/hyperactivity disorder (ADHD) are at increased risk of academic difficulties and special education placement (Barkley, 1998). One academic area, written expression, has received little research attention. This study assessed the effectiveness of a validated strategy instruction model--Self-Regulated Strategy…

It's use of psychotropic medications to treat an array of mental illnesses changes evaluations, treatment and emergency coverage. The rising abuse of its prescription drugs alters the campus party scene, and challenges pretenses about…
