Background: Children with intellectual and developmental disabilities (IDD) experience heightened attention difficulties which have been linked to poorer cognitive, academic and social outcomes. Although, increasing research has focused on the potential of computerised cognitive training in reducing attention problems, limited studies have…

Evidence to validate the use of fixed-time (FT) reinforcer delivery (i.e., noncontingent reinforcement) with typically developing populations has been relatively rare in the behavioral literature. In those studies that have provided validation, reinforcer delivery schedules appeared to be prohibitively dense for sustained implementation of…

Despite the potential impact nutrition may have on learning, there have been surprisingly few papers published directed towards the educational research community. In contrast, omega-3 supplementation studies are being frequently cited in the media, leading to parents asking for advice and guidance. The purpose of this article is to review the…

The aim was to characterize the panorama of developmental disorders in 208 preschool children with a clinical diagnosis of autism spectrum disorder (ASD), referred to a specialized centre, the Autism Centre for Young Children (ACYC), for intervention. At the centre, a research team examined all children according to structured protocols and…

This study identified a possible autistic spectrum subtype expressed through family psychopathology coupled with autistic probands' cognitive functioning (i.e., an endophenotypic profile). Participants included 24 children with Autism Spectrum Disorder (ASD) and 49 children with Learning Disorder (LD). There were significantly higher rates of Mood…

Like other developmental disorders such as Attention Deficit Hyperactivity Disorder, specific language impairment and dyslexia, there is no shortage of debate surrounding the condition of Developmental Coordination Disorder. The present article takes a global view of many of these debatable issues, starting with definition and terminology, moving…

While increasing numbers of articles and books refer to Attention Deficit Hyperactivity Disorder (ADHD) as a disorder of "executive function" of the mind, two conflicting views have emerged about how ADHD and executive function are related. In one view it is argued that some, but not all, who meet the fourth edition of the "Diagnostic and…

The emerging etiological model for developmental disorders, like dyslexia, is probabilistic and multifactorial while the prevailing cognitive model has been deterministic and often focused on a single cognitive cause, such as a phonological deficit as the cause of dyslexia. So there is a potential contradiction in our explanatory frameworks for…

Psychiatric evaluation of 14 males (ages 3-27 years) with the fragile X syndrome found pervasive hyperactivity, impulsivity, and attentional deficits, and a significant degree of anxiety. However, diagnostic criteria for persistent pervasive developmental disorder and autism were not met. (Author/DB)

This study compared executive functions in children with autism (N=40), Tourette syndrome (N=30), attention-deficit hyperactivity disorder (N=24), or controls (N=29). Groups differed in patterns of performance on the Wisconsin Card Sorting Task, a measure of flexibility, the Tower of Hanoi, a measure of planning capacity, and the Stroop, a test of…

This article reviews research on the behavioral and molecular genetics of reading and, where available, spelling. Recent research is summarized, suggesting that reading and spelling appear to share a common genetic basis, and that dyslexia lies on a genetic continuum with normal variance in reading skill. Research also suggests that while many of…

Explains characteristics of attention deficit hyperactivity disorder (ADHD): delay in self-regulation; living in the moment; difficulty remaining focused; lag in social development; and the positive characteristics of intuition, spontaneity, energy, creativity, and artistic skills. Sidebars discuss a neurobiological understanding of ADHD and tips…

Traditional diagnostic labels help professionals keep track of the types of problems children experience and help researchers study the causes of and treatments for those problems. But labels also pose significant limitations. First, by grouping different individuals together under a large category of what they appear to have in common, there is a…

Background: The executive functions of inhibition, planning, flexible shifting of actions, and working memory are commonly reported to be impaired in neurodevelopmental disorders. Method: We compared these abilities in children (8?12 years) with high functioning autism (HFA, n = 17), attention deficit-hyperactivity disorder (ADHD, n = 21) and…

Children and adolescents with disabilities are an extremely heterogeneous group of diverse learners, each with unique learning strengths and needs. Often misunderstood and frequently less served by the counseling profession, these children and adolescents need counseling services just as much as, if not more than, other children. Federal…
