| Outline of Final Research Achievements |
Bilateral cochlear implantation (CI) recipients with pervasive developmental disorder (1) felt uncomfortable with 2nd CI, which became tolerable by wearing 1st CI first, and 2nd CI afterward, and (2) showed poor progress in verbal expression with 1st CI, and rapidly caught up with normal hearing children with 2nd CI.
Postlingual hearing loss subjects with CI failed to distinguish vowels from vowel-like complex sounds. Auditory evoked response was similar with these two sounds. Prelingual CI recipients were able to distinguish vowels from vowel-like complex sounds. The P2N2 complex evoked by the vowel-like complex sounds was larger than that evoked by vowels.
