Developmental dyscalculia (DD) is marked by specific deficits in processing numerical and mathematical information despite normal intelligence (IQ) and reading ability. We examined how brain circuits used by young children with DD to solve simple addition and subtraction problems differ from those used by typically developing (TD) children who…

Research examining neuropsychological profiles of girls with Asperger's disorder (AD) is sparse. In this study, we sought to characterize neurocognitive profiles of girls with AD compared to girls with learning disabilities (LD). Two groups of school-age girls referred for neuropsychological assessment participated in the study. A total of 23…

This issue of "Learning Times" includes a feature on understanding dyslexia. Dyslexia is a brain-based, often inherited, disorder that impairs a person's ability to read. It is not the result of low intelligence, lack of motivation, sensory impairment, or inadequate instruction. Early diagnosis of dyslexia is critical, and a child can be…

Children with very low birth weight (VLBW, less than 1500 g) or very preterm birth (VPTB, less than 32 weeks gestational age or GA) have more mathematics disabilities or deficiencies (MD) and higher rates of mathematics learning disabilities (MLD) than normal birth weight term-born children (NBW, greater than 2500 g and greater than 36 weeks GA).…

This paper reviews literature supporting the notion that learning disabilities are presumed to be a result of central nervous system dysfunction. It focuses on the postmortem and neuroimaging studies that provide evidence of a neurological conceptualization of learning disabilities. (Author/JDD)

The article examines the fuctions of neurological and environmental variables in learning disabilities (LD). A behavior sequence approach is described which provides for the integration of both neurological and environmental variables. Implications of this approach for three categories of children (LD--no neurological dysfunction, no…

The relationship between neurological examinations and scores on the Quick Neurological Screening Test (QNST) was analyzed for 353 undifferentiated students in the general population and 204 students with known or suspected learning problems. No S shown to have a clearly abnormal neurological examination received a low score on the QNST. (CL)

This paper summarizes research currently being conducted on the biologic underpinnings of learning disorders, particularly dyslexia. The research findings discussed are derived from studying neuroanatomic, neurophysiologic, neurogenetic, neuroimaging, and behavioral characteristics in animal models that exhibit developmental brain anomalies and…

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)

Results of an experiment in which two speech sounds were presented simultaneously to the two ears in normal and unilaterally brain-damaged subjects suggest a role for the nondominant cerebral hemisphere in processing and/or storage of competing speech stimuli. (KW)

The structure and function of the nervous system as it puts us into contact with our environment is described. Section 1 presents a detailed discussion of the structure of the brain, drawing an analogy to a computer, and discusses the sensory input function. The transport system is then explained in a description of the transmission of sensory…

Neuropsychologically based intervention approaches for learning disabled students are reviewed. The approaches, which are in the areas of neurological organization, psycholinguistics, and perceptual motor skills, are also evaluated for their effectiveness in terms of theory and practice. (CJ)

A clinical psychologist describes an approach she uses to assess learning disabled students. She explains that brain function is analyzed through a sequence of tasks charting visual and auditory discrimination, perception, memory, organization, integration, and output. An example is cited in which an 11 year old child with traumatic brain injury…

A defense of the articles published in the September 1981 issue of "School Psychology Review" is provided. Concerns raised regarding the integration and application of neuropsychological knowledge in the school environment are addressed. Readers are urged to reevaluate their concepts regarding the learning problem child. (Author/AL)

The article discusses neuropsychological and treatment aspects of brain behavior disorders in children from the standpoint of terms such as minimal brain dysfunction, learning disabilities, hyperactivity, and hyperkinetic syndrome. (Author/DLS)
