Applies an extension of an earlier multiple regression model for twin analysis to the problem of detecting linkage in a quantitative trait. Detects a number of possible linkages, indicating that the approach is effective. Discusses detecting genotype-environment interaction and the issue of power. (RS)

Evaluates a substantially updated version of the "classical" idea of a significant relationship in dyslexic children between cerebral lateralization and their word decoding deficits. Finds further evidence that dyslexia is not related to incomplete lateralization. Suggests that dyslexics suffer from exuberant right hemisphere processing in…

A study investigated the effects of a new intervention paradigm on learning musical notation for five Dutch students with dyslexia and four typical students. Results found that the dyslexic children needed more time to learn musical notation, made more mistakes, and produced more "third transpositions." Implications for teaching are…

Adults with dyslexia displayed the following attitudes about time: (1) they felt intensive classroom time was essential; (2) they wanted class time to be focused on learning basics; (3) they never felt they got enough time from the tutor or volunteers; (4) group work led to insecurities about pace; and (5) despite these views, their attendance was…

Examined aspects of dyslexia as they became apparent during the construction of geometrical figures by one student as described by another, one of whom had dyslexic symptoms. Found that both dyslexic and non-dyslexic children encountered many communication problems, but that directional confusion of dyslexic students was one of the major…

Investigated the picture naming skills of dyslexic children, poor comprehenders and children with normally-developing reading skills, using pictures with names that varied in word length and frequency. Relative to young children reading at the same level, dyslexic children were less accurate naming pictures that have long names, and they made a…

Compares the effects of three kindergarten intervention programs on at-risk children's subsequent reading and spelling skills. Children potentially at risk for dyslexia (N=138) were assigned to one of three training conditions. Results indicate that combined training yielded the strongest effects on reading and spelling in Grades 1 and 2.…

This study investigated the relationship between dyslexia and speech perception, phonology, and morphology among 7-, 8- and 9-year-olds. Findings indicated that only the developmentally language impaired showed clear speech perception deficits. Phonological dyslexics and developmentally language impaired showed inflectional morphology…

A study of Hans Christian Andersen's diaries from age 20 to age 70 found that his mean error spelling percentages are equal to contemporaries, but between 2 and 15 times lower than individuals with dyslexia. A structural analysis indicates that the proportion of plausible/implausible errors match those of normal achievers. (Contains references.)…

Argues that motor and cognitive development may be fundamentally interrelated. Summarizes evidence of close co-activation of the neocerebellum and dorsolateral prefrontal cortex in functional neuroimaging, similarities in the cognitive sequelae of damage to dorsolateral prefrontal cortex and the neocerebellum, motor deficits in…

Examines phonological awareness at the level of phonemes and rhyme and relates this to nonword naming ability. Finds that phoneme awareness correlated significantly with poor readers' word and nonword reading ability, whereas rhyming skill did not. Concludes that phoneme awareness may be more important than rhyming skill in understanding reading…

Examines the assumption that the parvocellular system is suppressed by the magnocellular system during saccadic eye movements and that this visual deficit is associated with dyslexia. Evidence from six studies indicates the magnocellular system is suppressed during saccadic eye movements, disproving the magnocellular deficit theory of dyslexia.…

In this study, eight young adolescents with dyslexia were compared to age-matched controls on a number of speech and non-speech auditory tasks. Children with dyslexia had significantly higher thresholds in backward masking for bandpass noise than did control participants, but differed in no other way. (Contains references.) (Author/CR)

Investigates the relationship between controllability attributions for academic performance and the self perceptions of children with severe reading difficulties. Children identified as dyslexic were found to have significantly lower perceived scholastic competence than their normally achieving peers, but their global self worth was not…

Puts reading and spelling difficulties in a cognitive developmental perspective that views the acquisition of reading, writing, and spelling as a sequence of characteristic strategies for dealing with written language. Concludes that the ultimate goal is to reduce the great number of children who fail to acquire literacy due to teachers' lack of…
