The study investigates dyslexic and normal Hebrew readers' perception of words containing a vowel letter in different orthographic and morphological contexts. In the first experiment, 72 undergraduate education students (half diagnosed with reading disabilities and half normal readers) were asked to judge pointed words with different morphological…

One explanation for the relationship between serial rapid naming (SRN) and reading is that SRN affects the temporal proximity of the phonological activation of the letters in a word, which, in turn, influences the acquisition of orthographic knowledge. To test this hypothesis, a group of Dutch first grade children was trained in the rapid serial…

Recently, investigators have begun to pay increasing attention to the role of teachers' domain-specific knowledge in the area of reading, and its implications for both classroom practice and student learning. The aims of the present study were to assess kindergarten to third grade teachers' actual and perceived reading related subject matter…

The outcome of a training study attempting to increase German speaking poor readers' reading fluency is reported. The aim of the training was to help children establish orthographic representations for a limited set of training words as well as for high-frequency onset clusters. A sample of 20 dysfluent readers (8 to 11 years) received a …

This study examines morphological awareness in developmental dyslexia. While the poor phonological awareness of dyslexic children has been related to their difficulty in handling the alphabetical principle, less is known about their morphological awareness, which also plays an important part in reading development. The aim of this study was to…

This paper elaborates on components of a working definition of developmental dyslexia proposed in 1995 by G. R. Lyon. The 2003 revised definition, based on converging scientific evidence, was developed by a working group of the International Dyslexia Association. The new definition notes the condition's neurobiologic origin and typical presence of…

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…

This study developed a teacher knowledge survey that measured teacher knowledge of reading-related concepts. Use with 41 second- and third-grade teachers and then 103 third- and fourth-grade teachers found significant associations among teachers' knowledge, classroom reading achievement levels, and teachers' observed teaching competence. The…

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…

This study examined teacher education students' knowledge about word structure and improvements in their knowledge as a result of instruction, using three tasks: graphophonemic segmentation, classification of pseudowords by syllable type, and classification of real words as phonetically regular or irregular. Conclusions support the need for…

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…

Discussion of the teaching of writing, spelling, and reading using code-based literacy methods, such as Orton-Gillingham examines the cognitive challenge of the transition from spoken to graphic word and then reviews new research findings, such as the letter as model for sound variation, ease of spelling the low vowel, and the creation of word…

This study examined the interrelations of speech skills and letter knowledge to the phonological awareness and early reading skills of 99 preschool children. Findings indicated that phoneme awareness, but not rhyme awareness, correlated with early reading measures and that phoneme manipulation was closely associated with letter knowledge and with…

Perception and production of vowels in the words "pit,""pet," and "pat" were investigated with 19 adolescents with reading disabilities. Students with reading disabilities perceived and produced less well-defined vowel categories than a control group. Results suggest that speech processing difficulties of students with reading disabilities include…

Data from 123 male adults were analyzed to estimate environmental (home, school, and literacy environments) influences on components of literacy skills. Results suggest a substantial social-cultural bias in the delineation of literacy skills and in definitions of reading disabilities. Only phonological ability appeared relatively unaffected by…
