In this study, we examined the neuroanatomy of dyslexic (14 males, four females) and control (19 males, 13 females) children in grades 4-6 from a family genetics study. The dyslexics had specific deficits in word reading relative to the population mean and verbal IQ, but did not have primary language or motor deficits. Measurements of the posterior temporal(More)
OBJECTIVE To assess the effects of reading instruction on fMRI brain activation in children with dyslexia. BACKGROUND fMRI differences between dyslexic and control subjects have most often involved phonologic processing tasks. However, a growing body of research documents the role of morphologic awareness in reading and reading disability. METHODS The(More)
Thirteen male control and thirteen male dyslexic children (age, 121-152 months) were studied to determine if voxel based morphometry (VBM) could identify anatomical differences in the right cerebellar anterior lobe, and right and left pars triangularis that were identified with manual measures of the same children. VBM demonstrated significant gray and(More)
Using structural equation modeling the authors evaluated the contribution of morphological awareness, phonological memory, and phonological decoding to reading comprehension, reading vocabulary, spelling, and accuracy and rate of decoding morphologically complex words for 182 4thand 5th-grade students, 218 6thand 7th-grade students, and 207 8thand 9th-grade(More)
Dyslexia is a common heterogeneous disorder with a significant genetic component. Multiple studies have replicated the evidence for linkage between variously defined phenotypes of dyslexia and chromosomal regions on 15q21 (DYX1) and 6p22.2 (DYX2). Based on association studies and the possibility for functional significance of several polymorphisms,(More)
Results are reported for a study of 2 separate processes of report writing-taking notes while reading source material and composing a report from those notes-and related individual differences in executive functions involved in integrating reading and writing during these writing activities. Third graders (n = 122) and 5th graders (n = 106; overall, 127(More)
The purpose of this research is to address (a) whether individual differences in working memory (WM) and writing are related to a general or process-specific system, (b) whether WM tasks operate independently of phonological short-term memory (STM) on measures of writing and reading, and (c) whether working memory predicts variance in writing beyond that(More)
Four approaches to the investigation of connections between language by hand and language by eye are described and illustrated with studies from a decade-long research program. In the first approach, multigroup structural equation modeling is applied to reading and writing measures given to typically developing writers to examine unidirectional and(More)
BACKGROUND AND PURPOSE Diffusion tensor imaging is a tool that can be used to study white matter microstructure in dyslexia. We tested the hypothesis that dyslexics have a white matter structural change (as measured by directional diffusion of water, which can be affected by disruption in white matter tracts) between brain regions that previous functional(More)
Growth curve analyses showed that (a) word-level phonological and orthographic awareness show greatest growth during the primary grades but some additional growth thereafter, and (b) three kinds of morphological awareness show greatest growth in the first three or four grades but one-derivation-continues to show substantial growth after fourth grade.(More)
