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…

Five to seven percent of children experience severe difficulties in learning mathematics and/or reading. Current trials that are focused on identifying biological markers suggest that these learning disabilities, known as Developmental Dyscalculia (DD) and Dyslexia (for reading), are due to underlying brain dysfunctions. One ongoing controversy…

Limited research has been conducted on the structure of the pars triangularis (PT) in dyslexia despite functional neuroimaging research finding it may play a role in phonological processing. Furthermore, research to date has not examined PT size in ADHD even though the right inferior frontal region has been implicated in the disorder. Hence, one…

In line with current educational policy on inclusive education, the number of pupils with autistic spectrum disorders (ASD) attending mainstream schools is increasing. However, concerns remain about their experiences in school. In particular, previous research has suggested that such pupils are at an increased risk of social exclusion. In light of…

This study examined the relations between reading-related cognitive skills and word reading development of Chinese children with dyslexia in their Chinese language (L1) and in English (L2). A total of 84 bilingual children--28 with dyslexia, 28 chronological age (CA) controls, and 28 reading-level (RL) controls--participated and were administered…

Notes that since acquisition and utilization of multimodal and crossmodal information analysis seem to develop greatly during the two through four year age period in humans, it might be possible to identify potential dyslexics by early testing the adequacy of those functions. Limitations on the number of concepts that can be handled simultaneously…

Research is reviewed on eye movements during reading, on the perceptual span and control of eye movements during normal reading, and on the nature of eye movements in dyslexia. Rather than the cause of dyslexia, eye movements are said to reflect underlying cognitive or neurological problems. (CL)

Research on spatial thinking impairments, with special reference to right-left orientation, visuomotor and visuoconstructive performances, and finger recognition are examined. It is concluded that, although some dyslexic children do show spatial disabilities, there is little evidence to support the existence of a visuospatial type of developmental…

Reading performance of 46 poor readers was compared with that of 20 normal control readers. All Ss were second graders. Overall, the poor readers showed a slight tendency to be better at reading in the inverted position when the text must be scanned from right to left. (Author)

The article reviews current findings and theories concerning neurological bases of dyslexia. The involvement of hereditary factors is pointed out as well as irregularities in the brain's left hemisphere and patterns of electrical activity. (CL)

Theoretical constructs related to interpersonal and intrapersonal problem solving strategies in children with dyslexia are reviewed. H. Myklebust's hierarchies of language and experience are analyzed to demonstrate the importance of studying both the child and the teacher during the instructional process. (CL)

The author provides an overview of language variation in humans and comments upon the emergence of the concept of metalinguistics (awareness of using language). She discusses the contribution of metalinguistics to work with dyslexic persons. (CL)

This study investigated the role of the myelin oligodendrocye glycoportein (MOG) gene to reading disability in 22 children with dyslexia and 96 random controls. Results suggest that, although alleles in the MOG gene may be in linkage disequilibrium with a locus that contributes to reading disability, the MOG gene itself is probably not involved.…

The relationship between dyslexia and visual stress (sometimes known as Meares-Irlen syndrome) is uncertain. While some theorists have hypothesised an aetiological link between the two conditions, mediated by the magnocellular visual system, at the present time the predominant theories of dyslexia and visual stress see them as distinct, unrelated…

One of the most frequently cited papers from the twenty-five years of the Journal of Research in Reading is "Object-naming Deficits in Developmental Dyslexia" by Maggie Snowling, Bente van Wagtendonk and Carolyn Stafford, published in 1988. Looking back at the paper some sixteen years after its publication, it is striking to note how topical some…
