Musical and Verbal auditory cognition: child development and neurophysiological markers.
Abstract: This thesis project aims to better understand the deficits in musical and verbal short-term memory (STM) observed in dyslexic children and children with oral language disorders, as a large part of the learning disabilities are thought to originate from a central auditory disorder. The project is divided into two phases. The first phase consists in systematically measuring the musical and verbal STM performances of 100 children aged 5 to 10 years in order to explore their developmental characteristics. The second phase consists in using two different neuroimaging techniques: near-infrared spectroscopy (fNIRS) and magnetoencephalography (MEG). The first two fNIRS studies involved 40 healthy adults to identify neurophysiological markers of adult musical and verbal STM, validate the paradigm and the analyses. The third study consists in exploring the neurophysiological differences of these markers in a group of healthy children and a group of children with oral language disorders and dyslexia. The MEG study consists in exploring the neurophysiological differences between control and amusic participants, who present a specific neurodevelopmental disorder of music perception. Dyslexic individuals present an important comorbidity (30%) with amusia, characterizing the latter allows to explore the central auditory deficits common to dyslexics and amusics.
