The deaf children showed deficits in speech processing and temporality. They badly
apprehend temporal concepts and perceptions of deficit so the acoustic phenomena marking
the time course linguistically. Their prediction capabilities and anticipation
multisensory events are thereby affected, thus impacting their ability to adapt to
multiple and complex interaction possibilities that arise during a conversation.The
project aim it is to measure the impact of a musical rhythmic stimulation of neuronal
activity and the temporal prediction capabilities of older deaf children 5 to 8 years and
its impact on their language skills in a conversational task. A matched control group of
age will be examined for each of the proposed tasks.
We first measure the capacity to anticipate a situation of language interaction. For this
purpose, we will use an alternate naming paradigm with a virtual partner, already
developed and tested in children with normal hearing. This paradigm approaches the
conversational situation while allowing control of the time parameter of speech (speed of
trade) and by controlling the bias (temporal) inherent linguistic programming
difficulties of children in a spontaneous conversation situations .
Then we will couple behavioral measurements with measurements of eye movements and the
electroencephalogram (EEG) in deaf children. For this, we use a dialog observation task
already developed for normal hearing children. This task will allow us firstly to analyze
the anticipation level of speaking turns by analyzing eye movements (which "precedes" the
speaker). Secondly, it will allow us to study the effects of manipulation of the acoustic
parameters of auditory evoked potentials (AEP) and the oscillatory activity of the motor
system (EEG, mu rhythm and beta). The audiomoteur coupling would seem to be the key point
of anticipatory processes and convergence in conversational interaction will also be
studied using cortico-cortical coherence techniques to assess the dynamics of
connectivity between remote networks (system here auditory and motor system).
