During verbal communication individuals tend to align at different linguistic levels. Similarly, playing music requires fine temporal alignment and coordination abilities, in order to anticipate and adapt to other’s actions in real time. The aim of the project is to study the effect of musical rhythm on interpersonal verbal coordination in adults, children and children with hearing impairment. We will first quantify with behavioral and neural measures the interpersonal coordination during verbal exchanges. Then, we will test to what extent and how music training modifies these coordination metrics. The originality of the project lies in the use of a multilevel approach to conversation, front edge analysis techniques on speech and neural data. Importantly, this is the first attempt to study the effect of rhythmic joint-action (music) on different levels of language coordination in hearing impaired children.
