AB  - Cochlear implanted (CI) adults with acquired deafness are known to depend on 
      multisensory integration skills (MSI) for speech comprehension through the fusion 
      of speech reading skills and their deficient auditory perception. But, little is 
      known on how CI patients perceive prosodic information relating to speech 
      content. Our study aimed to identify how CI patients use MSI between visual and 
      auditory information to process paralinguistic prosodic information of multimodal 
      speech and the visual strategies employed. A psychophysics assessment was 
      developed, in which CI patients and hearing controls (NH) had to distinguish 
      between a question and a statement. The controls were separated into two age 
      groups (young and aged-matched) to dissociate any effect of aging. In addition, 
      the oculomotor strategies used when facing a speaker in this prosodic decision 
      task were recorded using an eye-tracking device and compared to controls. This 
      study confirmed that prosodic processing is multisensory but it revealed that CI 
      patients showed significant supra-normal audiovisual integration for prosodic 
      information compared to hearing controls irrespective of age. This study clearly 
      showed that CI patients had a visuo-auditory gain more than 3 times larger than 
      that observed in hearing controls. Furthermore, CI participants performed better 
      in the visuo-auditory situation through a specific oculomotor exploration of the 
      face as they significantly fixate the mouth region more than young NH 
      participants who fixate the eyes, whereas the aged-matched controls presented an 
      intermediate exploration pattern equally reported between the eyes and mouth. To 
      conclude, our study demonstrated that CI patients have supra-normal skills MSI 
      when integrating visual and auditory linguistic prosodic information, and a 
      specific adaptive strategy developed as it participates directly in speech 
      content comprehension.
