To evaluate the orthographic and phonological processing skills of developmental dyslexics, we (a) examined their abilities to exploit properties of orthographic redundancy and (b) tested whether their phonological deficit extends to spelling-to-sound connections for large-grain size units such as syllables. To assess the processing skills in…

The study investigated the relationship between vocabulary knowledge and novel word reading. Fourth-grade students were assessed on standardized measures of word identification, decoding, and receptive vocabulary, as well as on an experimental word identification measure using words that students in the fourth grade are unlikely to have seen…

This study explores whether activation and inhibition word processes contribute to the characteristic speed deficits found in transparent orthographies (Wimmer, "Appl Psycholinguist" 14:1-33, 1993). A second and fourth grade sample of normal school readers and dyslexic school readers participated in a lexical decision task. Words were…

To identify effective treatment for both the spelling and word decoding problems in dyslexia, 24 students with dyslexia in grades 4 to 9 were randomly assigned to treatments A (n = 12) or B (n = 12) in an after-school reading-writers' workshop at the university (thirty 1-h sessions twice a week over 5 months). First, both groups received step 1…

This study investigated whether children with dyslexia differed in their performance on reading, phonological, rapid naming, motor, and cerebellar-related tasks and automaticity measures compared to reading age (RA)-matched and chronological age (CA)-matched control groups. Participants were 51 children attending mainstream English elementary…

Dyslexia is hard to diagnose in a second language. Poor performance on a test of reading may be caused by poor language proficiency in the second language or by limited schooling rather than by poor reading ability per se. This confound was supported in a study of 88 adult second language learners and 65 native language speakers. The incidence of…

This research explored phonological and morphological awareness among Hebrew-speaking adolescents with reading disabilities (RD) and its effect on reading comprehension beyond phonological and word-reading abilities. Participants included 39 seventh graders with RD and two matched control groups of normal readers: 40 seventh graders matched for…

Reading fluency beyond decoding is a limitation to many children with developmental reading disorders. In the interest of remediating dysfluency, contributing factors need to be explored and understood in a developmental framework. The focus of this study is orthographic processing in developmental dyslexia, and how it may contribute to reading…

The primary purpose of this study was to explore if there could be a more beneficial method in organizing the individual instructional reading components (phonological decoding, spelling, fluency, and reading comprehension) within a remedial reading program to increase sensitivity to instruction for middle school students with reading disabilities…

The relative effectiveness of two computer-assisted instructional programs designed to provide instruction and practice in foundational reading skills was examined. First-grade students at risk for reading disabilities received approximately 80 h of small-group instruction in four 50-min sessions per week from October through May. Approximately…

We examined the Simple View of reading from a behavioral genetic perspective. Two aspects of word decoding (phonological decoding and word recognition), two aspects of oral language skill (listening comprehension and vocabulary), and reading comprehension were assessed in a twin sample at age 9. Using latent factor models, we found that overlap…

This study investigated the role of speech perception accuracy and speed in fluent word decoding of reading disabled (RD) children. A same-different phoneme discrimination task with natural speech tested the perception of single consonants and consonant clusters by young but persistent RD children. RD children were slower than chronological age…

We examined text memory in children with word reading deficits to determine how these difficulties impact representations of text meaning. We show that even though children with poor word decoding recall more central than peripheral information, they show a significantly bigger deficit relative to controls on central than on peripheral…

Developmental dyslexia is associated with functional abnormalities within reading areas of the brain. For some children diagnosed with dyslexia, phonologically based remediation programs appear to rehabilitate brain function in key reading areas (Shaywitz et al., Biological Psychiatry 55: 101-110, 2004; Simos et al., Neuroscience 58: 1203-1213,…

Malay is an alphabetic language with transparent orthography. A Malay reading-related assessment battery which was conceptualised based on the International Dyslexia Association definition of dyslexia was developed and validated for the purpose of dyslexia assessment. The battery consisted of ten tests: Letter Naming, Word Reading, Non-word…
