We examined the cognitive, language, and instructional predictors of early word-reading ability in a sample of children with Williams syndrome longitudinally. At Time 1, sixty-nine 6-7-year-olds (mean age = 6.53 years) completed standardized measures of phonological awareness, visual-spatial perception, vocabulary, and overall intellectual…

The present study examines the visual attention span deficit hypothesis in Chinese developmental dyslexia. Twenty-five Cantonese-speaking Chinese dyslexic children (DD group) were compared with 25 chronological-age-matched (CA) controls and another 25 reading-level-matched (RL) controls on their performance in visual attention span, reading, and…

Working memory is considered a well-established predictor of individual variation in reading comprehension in children and adults. However, how storage and processing capacities of working memory in both the phonological and semantic domain relate to reading comprehension is still unclear. In the current study, we investigated the contribution of…

The purpose of this study was to contrast three models of the RAN-reading relationship derived from the most prominent theoretical accounts of how RAN is related to reading: the phonological processing, the orthographic processing and the speed of processing accounts. Grade 4 Greek-speaking children (n = 208; 114 girls, 94 boys; mean…

This study was conducted to examine the factors that influence informational text comprehension and to determine how these vary for students with higher and lower component skills. The sample included 177 students in grades 3-5. Regression analyses were used to predict informational text comprehension with decoding efficiency, vocabulary…

The present study explored the early predictors of reading comprehension difficulties in Chinese children. We originally recruited 290 Beijing and 154 Hong Kong children and further selected from each sample those (30 from Beijing and 22 from Hong Kong sample) in the lowest 25% on reading comprehension tests across the last two consecutive testing…

The question of which cognitive impairments are primarily associated with dyslexia has been a source of continuous debate. This study examined the cognitive profile of Hebrew-speaking compensated adult dyslexics and investigated whether their cognitive abilities accounted for a unique variance in their reading performance. Sixty-nine young adults…

Using a large adult reading database, we examined the relationships between high-level and low-level reading skills and between multiple reading skills, general cognitive ability, and reading comprehension ability. A principal components analysis found partial dissociability between higher-level skills including reading comprehension, vocabulary…

Four hundred and ninety-five Japanese primary-school children aged from 8 (Grade-2) to 12 (Grade-6) were tested for their abilities to read/write in Hiragana, Katakana, and Kanji, for their size of vocabulary and for other cognitive abilities including arithmetic, visuo-spatial and phonological processing. Percentages of the children whose…

Details a project in which cognition, language, early literacy, phonological awareness, and reading skills were examined in a group of adolescents and children with Down syndrome and a group of typically developed children match for nonverbal cognition. Concludes that language was a strong predictor in the group with Down syndrome. (PM)

Comparing the analyses based on the data of 1,235 Chinese children referred for government services and subsequently diagnosed as children with dyslexia in Hong Kong and those of 690 Chinese children in the sample for the normative study of the Hong Kong Test of Specific Learning Difficulties in Reading and Writing, we explored the reading-writing…
