Development of Music Perception and Production and Speech Perception and Production by Cochlear Implant Users

对5-13岁接受人工耳蜗植入术的日本儿童和听力正常的日本儿童进行了语音韵律和音乐产生的知觉和产生的测试。对于韵律感知任务，他们被要求确定语义中性的话语是以快乐、悲伤还是愤怒的方式说话。儿童CI用户在听起来快乐和悲伤的话语上的表现低于上限，但在听起来悲伤的话语上的表现高于变化水平，但在愤怒的声音上没有表现。在韵律制作任务中，孩子们被要求模仿日语中表达失望和惊讶的刻板印象，以及典型的乌鸦和猫的声音。儿童CI用户的模仿与最小的(5-6岁)NH儿童没有显著差异。为了考察音乐创作的发展，三名儿童CI用户根据记忆演唱歌曲，并与5-6年前录制的歌曲进行比较。他们在计时方面的表现进一步提高，两个上了音乐课并接受了第二次植入的孩子在相对音调模式上有了很大的改善。

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.
