Specific reading disability (dyslexia): what have we learned in the past four decades?
TL;DR: Evidence is presented in support of the idea that many poor readers are impaired because of inadequate instruction or other experiential factors, and Hypothesized deficits in general learning abilities and low-level sensory deficits have weak validity as causal factors in specific reading disability.

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.

Sex differences in the functional organization of the brain for language

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
Disruption of posterior brain systems for reading in children with developmental dyslexia.

TL;DR: Brain activation patterns in dyslexic and nonimpaired children during pseudoword and real-word reading tasks that required phonologic analysis provided neurobiological evidence of an underlying disruption in the neural systems for reading in children with dyslexia.
Journal ArticleDOI
The Role of Instruction in Learning To Read: Preventing Reading Failure in At-Risk Children.
Barbara R. Foorman,David J. Francis,Jack M. Fletcher,Christopher Schatschneider,Paras D. Mehta +4 more
TL;DR: First and 2nd graders (N = 285) receiving Title 1 services received 1 of 3 kinds of classroom reading programs: direct instruction in letter-sound correspondences practiced in decodable text (direct code); less instruction in systematic sound-spelling patterns embedded in connected text (embe).
