Neurolinguistic Profiles of Dyslexia in a Longitudinal Perspective
Period: September 2011-September 2016
This project aims to investigate how advanced reading develops among three groups of children: Children with a familial risk of dyslexia who have developed the disorder, children with a familial risk of dyslexia who have not developed the disorder, and a control group without a familial risk of dyslexia. The children who take part in this study have been followed in the Dutch Dyslexia Program since they were 2 months old. Using behavioral and brain measures, including EEG, it will now be investigated how the phonological deficit that is characteristic of developmental dyslexia influences reading processes at the age of 11-12. It will also be investigated to what extend normalization or compensation has taken place in the children with Dyslexia and children who were at risk of dyslexia but have not developed the disorder. Special attention will be paid to lateralization, since previous studies have reported that children with dyslexia show more bilateral brain activation during reading, while the left hemisphere is more active during reading in control children. Furthermore, attention will be paid to the over-activation in the frontal regions of the brain which has been observed among people with dyslexia.
