| Outline of Final Research Achievements |
Audiovisual integration system in prelingually deafened children develops with long term use of cochlear implant. However, auditory input from the second implant in sequential bilateral cochlear implanted children significantly evoked audiovisual integration responses, which indicates incomplete auditory input through the second implant may influence more to start audiovisual integration than age or limited length of cochlear implant use. Audiovisual integration responses for bilateral cochlear implant use did not differ from those for monaural first implant use, suggesting that the audiovisual integration system in prelingually deafened bilateral cochlear implant children may work depending on the auditory input from the first implant. Neural system for audiovisual integration in prelingually deafened children may develop naturally through daily spoken language communication using cochlear implants without specific training program.
