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…

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)

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…

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.

The article focuses on the factors that have led to the current interest in the neuropsychology of learning disorders. The validity of the neuropsychological model is examined. Research regarding the neurobiological basis of learning disorders, cerebral asymmetries, and neuropsychological assessment batteries for learning disabilities are…

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)
