Throughout the various states of the USA, the appropriate identification of dyslexia and the timely provision of interventions are characterized by variability and inconsistency. Several states have recognized the existence of this disorder and the well-established need for services. These states have taken proactive steps to implement laws and…

This speech by a researcher into the genetic bases of dyslexia, attention deficit hyperactivity disorder (ADHD), and their etiological overlap, first honors four pioneers in the field (Samuel Orton, Bertil Hallgren, Isabelle Liberman, and Norman Geschwind); then updates knowledge about the genetics of dyslexia and comorbidity with ADHD and certain…

Reading Achievement, IQ, and behavior problems were assessed in second and eighth grade for a longitudinal sample of 57 children. "Matthew effects" did not occur for most of the children with learning disabilities, although a widening of the group difference in IQ was seen between the math disabled and nondisabled groups. Elevated rates of…

Thirty-seven experienced Dutch remedial teachers were asked to evaluate the potential effectiveness of various spelling exercises for children with spelling difficulties. Teachers preferred exercises with a combination of rule-based strategies and demonstration of the whole orthographic pattern of the word. Individual child characteristics did not…

This commentary reviews forthcoming articles on the scientific study of dyslexia, genetic and neurophysiological aspects of dyslexia, cross-linguistic aspects of literacy development and dyslexia, and theory-based practice. It concludes that educators should continue to strive to promote theory-based research and evidence-based practice to achieve…

This article reviews the contributions of Norman Geschwind on behavioral neurology. It discusses his novel associations between brain function/structure and behavior and findings from a recent study of 200 individuals with developmental disorders that indicate altered neuroanatomy in dyslexia may be accompanied by altered clinical neurophysiology.…

This article discusses the contributions of Margaret Byrd Rawson in the field of dyslexia. She was instrumental in the founding of the Jemicy School in Maryland, served as President of the International Dyslexia Association (IDA), and was on the IDA Council of Advisors at the time of her death.

A twin study involving 808 children with reading disability (RD) and 455 children with phonological disorder (PD) found each were heritable on their own. Further, even when correcting for RD, the two disorders were found to be co-heritable, indicating co-familiarity is at least partially driven by genetic influences. (Contains references.)…

A series of studies are reviewed that identify markers in the "event-related potentials" related to differences in the development of language and reading skills. In addition, home environment and other variables that influence the intellectual environment are linked with predictions of language and reading skill development. (Contains…

This article presents a theoretical overview at the cognitive level of the role of phonological awareness in reading development and developmental dyslexia across languages. It is argued that the primary deficit in developmental dyslexia in all languages lies in representing speech sounds: a deficit in phonological representation. (Contains…

This article examines how to interpret reading problems among individuals with a home language (L1) that is different from the language of instruction in school (L2). A tentative model is proposed where the various factors involved in L2 reading are specified, providing guidelines for assessment strategies. (Contains references.) (CR)

This article discusses using cross-language transfer as a diagnostic tool for identifying reading difficulties of language learners. It is argued that if children have enough exposure to and instruction in their first language, their skills and insights can be assessed and compared to skills and insights in their second language. (Contains…

Key components are outlined that represent the mindset of effective educators of students with learning disabilities, including: addressing the social-emotional needs of students, having empathy, recognizing educators have a lifelong impact on the development of resilience in students, avoiding accusations, blame, and labels, and striving to meet…

A study employed mixed effects regression growth curve analysis to assess the developmental course of discrepant (n=51) and nondiscrepant (n=89) poor readers identified in third grade and retested in fifth, eight, and twelfth grades. Discrepancy status did not differentiate the developmental course of basic reading skills or reading comprehension.…

A study assessed genetic and environmental etiologies of reading, rapid naming (RN), and their covariation using data from 587 twin pairs (ages 7-20) in which one student had reading difficulties and from 360 control pairs. Correlation between reading and RN performances for subjects was significantly higher than that of controls. (Contains…
