Dyslexia, History

A comprehensive history of Dyslexia by a researcher into the genetics of Dyslexia is available online as a PDF file. Another more detailed look at how ideas about Dyslexia have developed from a Clinical Neuropsychology point of view can be found here [PDF].

Dyslexia, Science, Visual

The latest issue of Journal of Cognitive Neuroscience includes a paper on the difficulties of dyslexics have with visual motion and how this relates to problems with reading.
“Developmental dyslexia is associated with deficits in the processing of visual motion stimuli, and some evidence suggests that these motion processing deficits are related to various reading subskills deficits. …. Results suggest that there are in fact two distinct motion processing deficits in developmental dyslexia, rather than one as assumed by previous research, and that each of these deficits is associated with a different type of reading subskills deficit. A deficit in detecting coherent motion is selectively associated with low accuracy on reading subskills tests, and a deficit in discriminating velocities is selectively associated with slow performance on these same tests. In addition, … The two distinct patterns of motion processing and reading deficits demonstrated by this study may reflect separable underlying neurocognitive mechanisms of developmental dyslexia.”

Commercial Dyslexia Centres & Treatments, Dore Achievement Centres, Science

The Dore Centres have released results from their independently run study at the Balsall Common School (West Midlands, UK). The first results were originally published in the journal Dyslexia (Abstract) in February 2003. This latest set of results carries on the study for another year and were presented to the British Dyslexia Association‘s International Conference in March 2004. By carrying on the study for an extra year it has been demonstrated that the children who have completed the programme not only catch up with their peers but that they maintain this equality and do not regress over time. The cerebellum / vestibular system retains its training for at least 12 months after training has stopped. Overall the study showed significant progress in dyslexia and attention related problems in the treated children and ruled out the results being caused by the placebo effect. A sixteen page document that is somewhere between a scientific research paper and a press release can be found on the Dore web site (MS Word document). Press coverage can be found in the Guardian, Daily Telegraph, Washington Times, BBC and The Scotsman.
