The current investigation explored the diagnostic utility of reading fluency measures in the identification of children with reading disabilities. Participants were 50 children referred to a university-based clinic because of suspected reading problems and/or a prior diagnosis of dyslexia, where children completed a battery of standardized…

Developmental exceptionalities span the range of learning abilities and encompass children with both learning disorders and learning gifts. The purpose of this article is to stimulate thinking about these exceptionalities, particularly the complexities and variations within and across people. Investigators tend to view learning disabilities or…

Limited research has been conducted on the structure of the pars triangularis (PT) in dyslexia despite functional neuroimaging research finding it may play a role in phonological processing. Furthermore, research to date has not examined PT size in ADHD even though the right inferior frontal region has been implicated in the disorder. Hence, one…

Fifty-five dyslexic and 30 normal readers (8-12 years old) were administered the K-ABC. Normal readers demonstrated significantly higher scores on the cognitive subtests of "Hand Movements,""Number Recall, Word Order," and "Matrix Analogies" as well as on each achievement subtest, the "Sequential" and…

Examines how neuropsychological research has increased understanding of the reading process and reading disabilities in children. Variations in impaired processes in reading disabilities can best be understood when brain-behavior relations involved in reading are conceptualized as a widespread functional system. Discusses implications for…

The exploratory study examined patterns of regional cerebral blood flow in a surface and a deep dyslexic during reading. Significant differences in gray matter blood flow were found between subjects and normal controls. Also differences existed between the surface and deep dyslexic in the distribution of cortical perfusion. (Author/DB)

Reviews computer tomography and magnetic resonance imaging studies examining deviations in brain morphology. Discusses methodological and technical issues. Concludes that dyslexics show variations in specific brain regions. Suggests that neuroimaging procedures appear to provide direct evidence supporting the importance of deviations in normal…

Research findings from autopsy studies, neuroimaging, functional imaging, and electrophysiological measures specific to dyslexia have provided a better understanding of the reading process, particularly as it applies to individuals with dyslexia. Evidence from these studies pertaining to the neurological origins of dyslexia is reviewed, and…

The risk for internalizing disorders in children with learning disabilities is frequently debated in the research community and empirical responses are equivocal. For educators and clinicians, the frequent assumption is that children with dyslexia also have at least subtle emotional problems. In this study, school-age children with reading…

The double-deficit hypothesis of dyslexia posits that reading deficits are more severe in individuals with weaknesses in phonological awareness and rapid naming than in individuals with deficits in only one of these reading composite skills. In this study, the hypothesis was tested in an adult sample as a model of reading achievement. Participants…

Reviews attempts to adequately define dyslexia with a focus on recent efforts at developing a nosology of dyslexia and discusses the neurological basis of reading and severe reading failure with an emphasis on validating evidence provided through brain-mapping procedures and postmortem studies. (HOD)

The article addresses the neuroimaging, electrophysiological, and postmortem evidence concerning the neurological basis of dyslexia and concludes that inconsistent findings may be related to limitations of investigative technologies. Correlates of reading ability and disability are discussed in a developmental-neuropsychological context.…

This article reviews Bakker's developmental neuropsychological model (the Balance Model) of reading development (EC 602 750), notes the need for validating research before employing these procedures in clinical practice, and raises some conceptual problems such as evidence that learning disability subtypes evolve over time. (Author/DB)

Children with Attention Deficit Disorder (ADD) often exhibit problems in visual spatial perception, math achievement, and social skills, and it has been postulated that this constellation of behaviors may constitute Right Hemisphere Deficit Syndrome (RHDS). This study examined 21 children with attention deficit disorder with hyperactivity (ADD/H),…
