These problems can be studied with the EEG method. The goal of this research was to examine 1) if the typically seen P1-N250-pattern, MMN and T-complex were observable in 9-year old children's ERPs, 2) if the same components could be seen in the source waveforms of a temporal source and 3) if there were differences in these source waveforms between children with dyslexia and typical readers. The EEG data was collected from 147 children (30 dyslexic, 57 typically reading risk children, 60 control children) with a 128-electrode net. The stimuli chosen were two naturally produced pseudowords /ata/ and /atta/ which were presented in an oddball-paradigm with an interstimulus interval of 610 ms. \n\nProminent P1-N250, MMN and T-complex patterns could be observed in the ERP waveforms. The P1-N250-complex was also seen in the source waveforms of the tangential orientation of the temporal source. The source waveform of the radial orientation showed a Tb-response. MMN could neither be seen for the short nor for the long speech stimulus. Groups differed in the processing of the stimuli's temporal characteristics which could be seen as differences in the N250-waveforms with dyslexic and typically reading risk children having bigger N250-responses than the control group. \n\nThe results show that dyslexic and typically reading risk children continue to have atypicalities in their speech processing even at the age of 9. However, these abnormalities are likely to be just one piece of the puzzle concerning the development of dyslexia. Further research on the neurocognitive risk factors of dyslexia is needed for the understanding of the dyslexia phenomenon and for the improvement of methods to identify and support the dyslexic children early in their development in an effective manner.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Maiju Uusipaikka (masuuuus) on 2013-05-23 06:17:59.471525.
