The "automatic letter-sound integration hypothesis" (Blomert, [Blomert, L., 2011]) proposes that dyslexia results from a failure to fully integrate letters and speech sounds into automated audio-visual objects. We tested this hypothesis in a sample of English-speaking children with dyslexic difficulties (N = 13) and samples of…

There appears to be a close and probably causal relationship between early variations in phoneme skills and later reading skills in typically developing children, though the pattern in children with Down Syndrome is less clear. We present the results of a 2-year longitudinal study of 49 children with Down Syndrome (DS) and 61 typically developing…

The study investigated cognitive deficits associated with dyslexia and familial risk of dyslexia (endophenotypes) by comparing children from families with and without a history of dyslexia. Eighty-eight school-aged children were assessed on measures of phonology, language and rapid automatized naming. A series of regression analyses with family…

The alphasyllabary of Kannada comprises more than 400 symbols called "akshara"; each symbol is visuo-spatially complex with a consistent representation at the dual levels of the syllable and the phoneme. We investigated reading difficulties in Kannada among 8-12 year old children by conducting a between-groups followed by a case series…

Background: This study evaluates the effects of a language and literacy intervention for children with Down syndrome. Methods: Teaching assistants (TAs) were trained to deliver a reading and language intervention to children in individual daily 40-min sessions. We used a waiting list control design, in which half the sample received the…

Reports on three studies comparing the reading and phonological skills of children with Down Syndrome (DS) and younger normally developing children of similar reading level. Notes that for children with DS, letter-sound knowledge did not predict reading. Suggests that children with DS do not possess full phoneme awareness. (PM)

The authors present the results of a 2-year longitudinal study of 90 British children beginning at school entry when they were 4 years 9 months old (range = 4 years 2 months to 5 years 2 months). The relationships among early phonological skills, letter knowledge, grammatical skills, and vocabulary knowledge were investigated as predictors of word…

Background: It is widely recognized that effective interventions for poor reading involve training in phoneme awareness and letter-sound knowledge, linked in the context of reading books. From the applied perspective, it is important to gather data on the effectiveness of different forms of implementation of literacy support within this framework.…

The authors report on a cross-linguistic investigation of the reading skills of 6- to 11-year-old children of English (an opaque orthography) and of Dutch (a transparent orthography). Dutch children were relatively more accurate and faster than English children of the same age at reading words and nonwords and also faster to complete phoneme…

We conducted a longitudinal study examining the role of phonemic awareness, phonological processing, and grammatical skills in the development of reading and spelling abilities in Greek. A battery of cognitive, linguistic, and literacy tasks was administered to 131 primary school children (65 7-year-olds and 66 9-year-olds) and was repeated in the…

Two groups of adolescents with language impairment (n=87) were compared with 20 adolescents with dyslexia, 19 aged-matched controls, and 18 younger typical children. Adolescents with dyslexia only performed as well as those with persistent oral language impairments and younger controls in reading and spelling, however, their reading comprehension…

Examines the development of grapheme-phoneme conversion ability in normal and reading-age matched dyslexic readers. Thirty-six normal readers (mean age 9.5 years) and 18 children diagnosed dyslexic (mean age 12.1 years) served as subjects. (MP)

Followed development of children at family risk for dyslexia from 3 years to 8 years. Found that 66 percent of high-risk group had reading disabilities at age 8 compared with only 13 percent in a control group. However, family risk of dyslexia was continuous. Interpreted findings within a model in which problems in establishing a phonological…

Background: We evaluate the effectiveness of three theoretically motivated programmes for the teaching of reading to four-year-old children. Method: Four hundred and ten children, of pre-kindergarten age, in 20 UK Reception-year classrooms were divided into four matched groups and randomly assigned to one of three experimental teaching conditions,…
