Recent research suggests that visual-verbal paired associate learning (PAL) may tap a crossmodal associative learning mechanism that plays a distinct role in reading development. However, evidence from children with dyslexia indicates that deficits in visual-verbal PAL are strongly linked to the verbal demands of the task. The primary aim of this…

The present study examined the effects of orthographic transparency on reading ability of children with dyslexia in two Hebrew scripts. The study explored the reading accuracy and speed of vowelized and unvowelized Hebrew words of fourth-grade children with dyslexia. A comparison was made to typically developing readers of two age groups: a group…

Dyslexia is a neuro-cognitive disorder with a strong genetic basis, characterized by a difficulty in acquiring reading skills. Several hypotheses have been suggested in an attempt to explain the origin of dyslexia, among which some have suggested that dyslexic readers might have a deficit in auditory temporal processing, while others hypothesized…

The current study investigated which time components of rapid automatized naming (RAN) predict group differences between dyslexic and non-dyslexic readers (matched for age and reading level), and how these components relate to different reading measures. Subjects performed two RAN tasks (letters and objects), and data were analyzed through a…

This paper investigates Spanish dyslexic spelling abilities: specifically, the influence of syllabic linguistic structure (simple vs consonant cluster) on children's spelling performance. Consonant clusters are phonologically complex structures, so it was anticipated that there would be lower spelling performance for these syllabic structures than…

Individuals with acquired phonological dyslexia experience difficulty associating written letters with their corresponding sounds, especially in pseudowords. Several studies have attempted to improve reading in this population by training letter-to-sound correspondence, general phonological skills, or a combination of these approaches; however,…

Whereas most English language sub-typing schemes for dyslexia (e.g., Castles & Coltheart, "1993") have focused on reading accuracy for words varying in regularity, such an approach may have limited utility for reading disability sub-typing beyond English in which fluency rather than accuracy is the key discriminator of developmental and individual…

We tested the hypothesis that the acquisition of orthographic knowledge of novel words that are presented in an indistinct context, that is a context with many orthographically similar words, would be more difficult for dyslexic than for normal readers. Participants were 19 Dutch dyslexic children (mean age 10;9 years), 20 age-matched and 20…

The ability to identify stop consonants from brief onset spectra was compared between a group of Chinese children with phonological dyslexia (the PD group, with a mean age of 10 years 4 months) and a group of chronological age-matched control children. The linguistic context, which included vowels and speakers, and durations of stop onset spectra…

Discusses Samuel Orton's writings on cerebral dominance and effects of certain neurological anomalies on learning. (WR)

We summarize some of the most important findings from research evaluating the hypothesized causes of specific reading disability ("dyslexia") over the past four decades. After outlining components of reading ability, we discuss manifest causes of reading difficulties, in terms of deficiencies in component reading skills that might lead to such…

Included in this book are sections dealing with: (1) some clinical experiences with poor readers; (2) the history of the letters "H" and "T," the biology of righthandedness, the silent "E," and code vs. meaning; (3) the irregular spelling of English words and differences between vowels and consonants; (4) the silent "E" at the end of words,…

This book, first of all, is a personal document, a revelation of the struggles of a bright, determined child and his family in understanding and coping with his severe language disability. Secondly, it is a guide for parents, directing them to the danger signals which may indicate future language problems in their children and taking them through…

The purpose of this study was to determine whether primary dyslexic children are impaired equally in the areas of language and cognition and to assess the value of verbal cues in raising the dyslexic group's performance on word-retrieval tasks. Two groups of male children were used in the investigation. The experimental group consisted of primary…

This paper summarizes several research studies related to reading and writing disabilities in children. The major purpose of these investigations was to test some of the German theories on dyslexia, especially regarding visual perceptual problems, spatial orientation, and dominance factors. The dyslexic child, as defined in Germany and used in…
