Is there a link between dyslexia and atypical brain lateralization?
Is the atypical brain lateralization, if present, a cause or a consequence of dyslexia?
Since Samuel Orton’s times – meaning for almost 100 years now (Orton, S., 1925), scientists have been looking for the answers of these questions and still do not have conclusive results even for the first one. The data in the scientific literature is inconsistent and sometimes even conflicting. That may be due to the assessment tools chosen, to the small sample sizes, to the heterogeneity of dyslexia or to a combination of these factors.
An online laterality battery of validated behavioural tests (verbal, visual and motor) might have a huge contribution in the right direction, as it enables easily testing a big sample of dyslexics all over the world, thus providing statistically significant results. Proving or disproving the link between dyslexia and atypical brain lateralization, will give us a green light to really focus on a third question, which I, as a practitioner and not only a researcher, consider actually the most important – How can we use that knowledge for better tailored interventions?
The study is for school-aged children (8-17 y.o.) with the official diagnosis of Dyslexia. It is relatively quick, it is fun and it is anonymous, but all the interested families may know their child’s individual results on request.
