The Validity of Perceptual Deficit Explanations of Reading Disability: A Reply to Fletcher and Satz.
Peer reviewedVellutino, Frank R. – Journal of Learning Disabilities, 1979
In the article the author refutes J. Fletcher and P. Satz's analysis of the etiology of reading disability on logical, theoretical, and empirical grounds. (Author/PHR)

Peer reviewedFletcher, Jack M.; Satz, Paul – Journal of Learning Disabilities, 1979
In the rejoinder the authors describe the methodological and interpretive factors in the Vellutino et al, experiments which limited the degree to which the studies refuted perceptual deficit hypotheses of reading disability. Note: for more of the interchange see EC 114 687-688. (Author/PHR)

Ratner, Vivienne – 1988
The paper examines issues concerned with the incidence of visual perceptual learning disabilities among deaf and partially hearing children. Evidence indicating a high incidence (15.5 percent of 682 deaf students) of visual perceptual deficits is offered, as is a definition of visual perception. The impact of visual perceptual deficits on…

Twenty-one children (approximate ages 6 to 16), drawn from the larger pool of 100, with Tourette's Syndrome were evaluated to: (1) determine the prevalence of learning disorder in this population; (2) identify particular areas of academic difficulty; and (3) consider the spectrum of central nervous system processing deficits in these children. Not…
