The purpose of my thesis work is to better understand the brain plasticity and transfer of learning in children through two cognitive activities : music and language. To this end, I conducted two longitudinal studies to better understand the influence of musical training on cognitive processing involved in language (prosody). These experiences are based on methods from experimental psychology (reaction time measure and percentage of errors) and electrophysiology in humans (Evoqued potentials). The results show that learning music influenced pitch discrimination in language but that influence is modulated by the duration of the training. They also underline significant effects of brain plasticity. Then, I participated in a study aimed at exploring the influence of musical expertise on the prosodic treatment of a foreign language, Portuguese. The results of this study point out that musical expertise facilitates the processing of prosodic aspects of a foreign language. Finally, I participated in a study to determine the influence of a visual-auditory training in dyslexic children. The results show that dyslexic children have a deficit in pitch discrimination in language, but this deficit can be remedied by visual-auditory training.
