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.
Sex differences in the functional organization of the brain for language
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.

This chapter discusses classification, definition, and identification of Learning Disabilities, as well as assessment of learning disabilities, and their applications in reading and mathematics.
Cerebral organization of component processes in reading.
The cerebral organization of word identification processes in reading was examined using functional magnetic resonance imaging (fMRI) and a strategy of multiple subtractions was employed in order to validate relationships between structure and function.
The cognitive correlates of third-grade skill in arithmetic, algorithmic computation, and arithmetic word problems
The purpose of this study was to examine the cognitive correlates of 3rd-grade skill in arithmetic, algorithmic computation, and arithmetic word problems. Third graders (N = 312) were measured on…
