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

日本5至13岁的儿童谁使用人工耳蜗植入物（CI）和正常听力（NH）的日本儿童的对照组进行了测试，他们的感知和生产的语音韵律和音乐生产。在韵律感知任务中，他们被要求判断语义中性的话语是以快乐、悲伤还是愤怒的方式说出的。儿童CI用户执行低于上限，但以上的变化水平上的快乐和悲伤的冠冕堂皇的话语，但不是愤怒的soundingutterances。在韵律产生任务中，儿童被要求模仿刻板的日本话语，表达失望和惊讶，以及文化上典型的乌鸦和猫的声音。儿童CI用户的模仿没有显着差异，从最年轻的（5-6岁）NH儿童。为了研究音乐制作的发展，三名儿童CI用户根据记忆唱歌曲，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改善，对于两个一直在上音乐课并接受第二次植入的孩子来说，相对音高模式有了很大的改善。

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.
