This study examined developmental profiles of reading fluency and reading comprehension in Grades 1 to 9 (ages 7 to 15) in a large Finnish sample (N = 2,518). In addition, early predictors of the profiles were analyzed with respect to kindergarten cognitive skills (phonological awareness, letter knowledge, rapid automized naming [RAN], number…

New findings are presented for children in Grades 1 to 9 who qualified their families for a multigenerational family genetics study of dyslexia (impaired word decoding/spelling) who had either superior verbal reasoning ("n" = 33 at or above 1 2/3 standard deviation, superior or better range; 19% of these children) or average verbal…

Researchers have used various theories to explain deaf individuals' reading skills, including the dual route reading theory, the orthographic depth theory, and the early language access theory. This study tested 4 groups of children--hearing with dyslexia, hearing without dyslexia, deaf early signers, and deaf late signers (N = 857)--from 4…

This study aims to enhance understanding of the factors underlying variance in the reading comprehension skills of prelingually deaf individuals. Participants were 213 sixth through tenth graders with prelingual deafness recruited from four orthographic backgrounds (Hebrew, Arabic, English, and German) and allocated to three distinct reading…

Purpose: A mixed-methods approach, evaluating triple word-form theory, was used to describe linguistic patterns of misspellings. Method: Spelling errors were taken from narrative and expository writing samples provided by 888 typically developing students in Grades 1-9. Errors were coded by category (phonological, orthographic, and morphological)…

Two instructional experiments used randomized, controlled designs to evaluate the effectiveness of writing instruction for students with carefully diagnosed dyslexia, which is both an oral reading and writing disorder, characterized by impaired "word" decoding, reading, and spelling. In Study 1 (4th to 6th grade sample and 7th to 9th grade…

This study was an investigation of several Arabic reading measures among dyslexics and normal Arabic readers across different ages (grades 3, 6, 9, and 12): the role of morphology, short vowelization (phonological and syntactic skills), spelling, reading isolated words, and reading comprehension. The results of the one-way ANOVAs indicated clear…

A sample of 131 10--14-year-old Dutch children with reading and spelling difficulties received a treatment for dyslexia. The treatment was computer-based and focused on learning to recognise and use the phonological and morphological structure of Dutch words. The treatment consisted of several modules, each addressing specific links between…
