Cross-cultural studies have suggested that reading deficits in developmental dyslexia (DD) can be moderated by orthographic depth. To further explore this issue and assess the moderating role of orthographic depth in the developmental cognitive trajectories of dyslexic and typical readers, we systematically reviewed 113 studies on DD that were…

Previous studies have showed that early problems with word decoding can lead to poor performance in text reading and comprehension and suggest that poor readers often struggle with reading deficits throughout their school years. Therefore, early detection of those children who are at risk for slow reading development and/or who belong to the…

Recent studies show that dyslexia persists into adulthood, even in highly educated and well-read people. The main characteristic that adults with dyslexia present is a low speed when reading. In Spanish, a shallow orthographic system, no studies about adults with dyslexia are available; and it is possible that the consistency of the orthographic…

Research and clinical practitioners have mixed views whether reading and spelling difficulties should be combined or seen as separate. This study examined the following: (a) if double dissociation between reading and spelling can be identified in a transparent orthography (Finnish) and (b) the cognitive and noncognitive precursors of this…

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…

The purpose of the present study was to explore the possibilities for the assessment of growth in phonological awareness of children in kindergarten and first grade. Phonological awareness was measured using four sets of items involving rhyming, phoneme identification, phoneme blending, and phoneme segmentation. The results of an exploratory…

To investigate the relationship between reading accuracy and speech processing, 20 skilled readers (grades 2-3) were compared with 20 less skilled readers on a speech perception and production task. The vowel phonemes were less securely represented in the perceptual systems of the less skilled readers than were consonant phonemes. (Author/CR)

A study found children (ages 7-12) with difficulties in phonemic awareness and word identification who received Fast ForWord (FFW) training (n=11) and Orton Gillingham (OG) training (n=9) made similar gains in phonemic awareness. Unlike children who received FFW, children who received OG training made significant gains in word attack. (Contains…

Two groups of first graders (n=63) participated in a 10-day intervention study in which they were instructed in the spelling of five final letter patterns in monosyllabic words. Children receiving phoneme instruction improved accuracy of final pattern spelling as well as speed of word reading over children receiving rime instruction. (Contains…

A study involving 18 children with reading difficulties (grades 4- 9), 33 children controls, and 19 adult controls found that poor readers have less difficulty reading words whose forms are phonologically and orthographically transparent than reading words the base forms of which undergo a phonological shift when a suffix is added. (Contains…

This study of 508 Israeli kindergarten children learning to read Hebrew found that phonemic segmentation skills and reading acquisition are highly interrelated. Learning to read was the main factor accounting for the sharp increase in phonological awareness between six and seven years of age, and reading acquisition was facilitated by prior…

A study involving a high-school student with hyperlexia and a student with above average word recognition skills, found they scored higher on Spanish proficiency tasks that required the exclusive use of phonological and phonological/orthographic skills than on Spanish proficiency tasks requiring listening comprehension and speaking and writing…

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…

This article presents a theoretical overview at the cognitive level of the role of phonological awareness in reading development and developmental dyslexia across languages. It is argued that the primary deficit in developmental dyslexia in all languages lies in representing speech sounds: a deficit in phonological representation. (Contains…

The role of information processing deficits in poor readers of nonalphabetic scripts such as Chinese is not well documented. Here, we examined perceptual processing in good and poor readers of Chinese. Specifically, two groups of third grade children comprising 20 "good readers" and 19 "poor readers," drawn from a larger pool of 254 students, were…
