Bennett A. Shaywitz,Sally E. Shaywitz,Kenneth R. Pugh,Robert Todd Constable,Pawel Skudlarski,Robert K. Fulbright,Richard A. Bronen,Jack M. Fletcher,D.P. Shankweiler,Leonard Katz,John C. Gore +10 more
TL;DR: For instance, this paper found that brain activation in males is lateralized to the left inferior frontal gyrus regions; in females the pattern of activation is very different, engaging more diffuse neural systems that involve both the left and right inferior frontal cortex.
Journal ArticleDOI
Sex differences in the functional organization of the brain for language
Bennett A. Shaywitz,Sally E. Shaywltz,Kenneth R. Pugh,Kenneth R. Pugh,R. Todd Constable,Pawel Skudlarski,Robert K. Fulbright,Richard A. Bronen,Jack M. Fletcher,Donald Shankweiler,Leonard Katz,John C. Gore +11 more
TL;DR: The data provide clear evidence for a sex difference in the functional organization of the brain for language and indicate that these variations exist at the level of phonological processing.
Journal ArticleDOI
Functional disruption in the organization of the brain for reading in dyslexia
Sally E. Shaywitz,Bennett A. Shaywitz,Kenneth R. Pugh,Robert K. Fulbright,Robert Todd Constable,W.E. Mencl,Donald Shankweiler,Alvin M. Liberman,P Skudlarski,Jack M. Fletcher,Leonard Katz,Karen E. Marchione,Cheryl Lacadie,C Gatenby,John C. Gore +14 more
TL;DR: Using functional magnetic resonance imaging to compare brain activation patterns in dyslexic and nonimpaired subjects as they performed tasks that made progressively greater demands on phonologic analysis supports a conclusion that the impairment in Dyslexia is phonologic in nature.
Journal ArticleDOI
Cognitive profiles of reading disability: Comparisons of discrepancy and low achievement definitions.
Jack M. Fletcher,Sally E. Shaywitz,Donald Shankweiler,Leonard Katz,Isabelle Y. Liberman,Karla K. Stuebing,David J. Francis,Anne E. Fowler,Bennett A. Shaywitz +8 more
TL;DR: Results did not support the validity of discrepancy versus low achievement definitions and differences between those children with impaired reading who met IQ-based discrepancy definitions and those who met low reading achievement definitions were small or not significant.
Book ChapterDOI
The reading process is different for different orthographies : the orthographic depth hypothesis
Leonard Katz,Ram Frost +1 more
TL;DR: In this paper, the authors discuss the varying dependence on the alphabetic principle may mean for the mental processes involved in reading and writing, and the degree of this dependence is a function of a language's characteristic phonology and morphology, just as was the choice of the kind of orthography itself.
