Children Deafness Clinical Trial
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).
