In search for neurophysiological markers for an auditory processing deficit in dyslexia.
in het Engels (max. 15 regels): The etiology of developmental dyslexia remains widely debated. One theory postulates that the reading and spelling problems in dyslexia originate from reduced sensitivity to the temporal envelope of speech. This low-level auditory deficit is thought to provoke a cascade of effects, including underspecified phonological representations and inaccurate speech perception. However, neural evidence for the presence of this deficit in dyslexia is scarce. This project aims to investigate the neural nature of the temporal envelope processing deficit in dyslexia by investigating neural responses to basic auditory temporal envelope information as well as directly to the speech envelope. Furthermore, we aim to investigate the possibility to improve neural processing of the speech envelope by enhancing particular envelope cues in the speech signal and to unravel whether this speech enhancement strategy is also beneficial for individuals with dyslexia. Besides its theoretical relevance, this project strives to contribute to the discovery of specific neurophysiologic markers for dyslexia, important for the early detection of dyslexia, and to explore possible strategies to entrain sensitivity to temporal auditory cues and to improve speech perception abilities of individuals with dyslexia.
