The primary purpose of this study was to investigate the various neurocognitive processes concomitant to reading by attempting to identify various subtypes of reading disorders in a referred sample. Participants were 216 elementary school students in grades two through five who were given select subtests of the Woodcock Johnson-III Tests of…

Objective: Studies of healthy individuals and those with cerebellar damage have implicated the cerebellum in a variety of cognitive and behavioral processes. Decreased cerebellar volume has been found in children with attention-deficit/hyperactivity disorder (ADHD) and differentially related to behavioral outcomes. The present study investigated…

Genetics contributes importantly to learning abilities and disabilities--not just to reading, the target of most genetic research, but also to mathematics and other academic areas as well. One of the most important recent findings from quantitative genetic research such as twin studies is that the same set of genes is largely responsible for…

Students with strong executive function skills hold the keys to school and social success--from attention and impulse control to time management and organization. Now K-12 teachers have a practical, highly readable guide to enhancing these critical skills for "all" students, with and without learning disabilities. Through the author's memorable…

Fundamental assumptions concerning the cause of learning disabilities are described and criticized. At a broader level, research and theory in three different paradigms are discussed: (1) neuropsychological; (2) information processing; and (3) applied behavior analysis. Four recommendations for future progress in the conceptualization and…

The study compared the Halstead-Reitan (H-R) neuropsychological test profiles of 25 normal, 47 learning disabled (LD) and 20 brain damaged (BD) young adults. Multivariate analyses indicated that the H-R battery could differentiate these groups beyond chance expectancy and that the neuropsychological deficits in LD performance are intermediate in…

The paper traces the development of an integrated model of cognition stemming from Soviet neuropsychology and reviews recent research on simultaneous and successive syntheses. Implications for mental retardation, learning disability, hyperactivity, and reading disability are given. (Author/CL)

Intended for pediatricians, the article considers aspects of diagnosis and treatment of learning problems including definitions and documentation, the examination, developmental lag, intelligence and psychometry, reversals, serial ordering, cognitive processes in reading, and hyperactivity. (DB)

Response to intervention (RTI) must be combined with comprehensive cognitive assessment to identify children with learning disabilities. This article presents the Cognitive Hypothesis Testing (CHT) model for integrating RTI and comprehensive evaluation practices in the identification of children with reading disabilities. The CHT model utilizes a…

In response to articles concerning the author's earlier paper, the paper responds to criticisms concerning contextualism, the role of metatheory, distinctions between basic and applied research, cognitive components and specificity, the science of learning disabilities, neurological indices, model validation, and the nature of learning…

The paper deals with the effects of general experiences and specific educational practices on the structure and functioning of the central nervous system. (CL)

Recent advances in neuroimaging and genetics technologies have enhanced our understanding of neurodevelopmental disorders in adults. The authors in this volume not only discuss such advances as they apply to adults with learning disorders, but also address their translation into clinical practice. One cluster of chapters addresses developmental…

This study examines executive function and its relationship to attention dysfunction and working memory. It attempts to document the manifestations of executive function problems in school-related extended processing tasks, such as verbal problem-solving in math and reading of extended passages. Subjects (in grades 1-12) included 49 children with…

This paper examines the neurobiology of fluid cognitive functions of the prefrontal cortex and considers learning disability as a specific example of a group of developmental disorders characterized by fluid skills impairment in the presence of crystallized intelligence in the normal range. Research indicating fluid cognitive impairments in…

Describes recent research findings in the area of neurobiology and its relationship to learning and memory. The article provides definitions of associative and nonassociative learning, identifies essential memory trace circuits of the mammalian brain, and discusses some neural mechanisms of learning. (TW)
