Findings from a prospective longitudinal study of math disability (MD) addressed its incidence during primary school, the utility of different MD definitions, and evidence of MD subtypes. Findings indicated only 22 of 209 participants demonstrated "persistent MD"; reading disability was more frequent in this group; and reading related skills and…

This paper reports on the development of a battery of phonological processing tasks to screen adults with dyslexia. Tasks examined reversed spoonerism, phonological choice, working memory, and vocabulary with confusable alternatives. All tasks showed high discrimination between adults with dyslexia and a control group. Tasks also correlated with…

This paper describes characteristics of 10-year-old children (n=422) with normal reading ability, but with some signs of dyslexia. Findings indicated these children obtained different results on five measures associated with dyslexia than did other normal achievers without such signs. Measures were underachievement at word recognition, spelling,…

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.

Preliminary results from data on 146 Australian, 284 American, and 70 Norwegian preschool twins indicate reliable genetic influences on phonological awareness and memory and learning. Vocabulary, grammar, and morphology showed significant shared environment and negligible genetic effects. A print knowledge composite showed genetic and shared…

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.)…

This article focuses on methods useful for identifying differences in the development of language reading abilities in children that rely on measures of brain responses and behavioral assessments. Findings from these methods are described and indicate that even behaviors strongly influenced by biological mechanisms can be influenced through…

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…

A study investigated relationships among 59 elementary teachers' reading-related content knowledge, their philosophical orientation toward reading instruction, their classroom practice, and their students' learning. Relationships emerged between content knowledge and instruction and between kindergarten teachers' phonological knowledge and their…

Twenty-four first-graders who were taught reading skills using the "Language Basics: Elementary" program, which incorporates the Orton-Gillingham-based Alphabetic Phonics Method, made statistically significant gains in phonological awareness, decoding, and reading comprehension. Thirty-two controls taught with the Houghton-Mifflin Basal Reading…
