| Research Abstract |
Japanese 5-to 13-yr-olds who used cochlear implants(CIs) and a comparison group of normally hearing(NH) Japanese children were tested on their perception andproduction of speech prosody and music production. For prosody perception task, they were asked to determine whether semantically neutral utterances were spokenin a happy, sad, or angry manner. Child CI users performed below ceiling but above change levels on happy-and sad-sounding utterances but not on angry-soundingutterances. For the prosody production task, children were asked to imitate stereotyped Japanese utterances expressing disappointment and surprise as well as culturally typical representations of crow and cat sounds. Child CI user's imitations did not differ significantly from youngest(5-6 yr-olds) NH children. To examine development of music production, three child CI users sang songs from memory and compared from songs recorded 5-6 years ago. Their performances on timing further improved and for the two children who had been taking music lessons and received second implants showed large improvements on relative pitch patterns.
