项目摘要
DESCRIPTION (provided by applicant): Natural variations in the pitch of spoken utterances convey important linguistic and emotional information to the listener. For children in particular, these prosodic cues are critical in the early stages of language learning. In tonal languages, the rapid changes in pitch carry lexical meaning. For young children, therefore, the ability to hear subtle differences in voice pitch is of great importance during the early years as they acquire their native language. Little, however, is known about children's sensitivity to subtle changes in voice pitch. Today, children who were born deaf or lost their hearing early in life routinely receive cochlear implants. Although cochlear implants facilitate the perception and acquisition of spoken language well, they are limited in the amount of voice pitch information that can be transmitted to the listener. It is, however, still possible that the early-implanted brain of young children, which is more adaptive than that of adults, may be able to overcome the limitations of the device to some extent. The goals of this project are to: i) measure the psychophysical sensitivity of school-aged normally hearing and cochlear-implanted children to changes in voice pitch; ii) quantify children's ability to process speech intonation and lexical tones using different acoustic cues when voice pitch is degraded; iii) quantify cochlear-implanted children's performance in similar tasks. The results of these studies will shed important new light on young children's sensitivity to voice pitch cues, how cochlear implantation might influence this sensitivity, and the extent to which the early-implanted auditory system can overcome an important limitation of the prosthesis.
PUBLIC HEALTH RELEVANCE: The natural variations of voice pitch in everyday speech convey important linguistic information and are particularly important for language-learning by young infants and children. Little is known about young children's sensitivity to voice pitch, and children with profound hearing loss who have received a cochlear implant are at a particular disadvantage in regard to voice pitch information. The results of the present study will shed light on basic mechanisms of voice pitch processing by normally-hearing and cochlear-implanted children as they develop from age 6 to young adulthood.
描述(由申请人提供):口语音调的自然变化向听众传达了重要的语言和情感信息。特别是对于儿童来说,这些韵律提示在语言学习的早期阶段至关重要。在声调语言中,音高的快速变化具有词汇意义。因此,对于幼儿来说,在他们学习母语的早期阶段,能够听到音调的细微差别非常重要。然而,人们对儿童对音高细微变化的敏感性知之甚少。如今,出生时耳聋或早年丧失听力的儿童通常会接受人工耳蜗植入。尽管人工耳蜗可以很好地促进口语的感知和习得,但它们可以传输给听者的音高信息量有限。然而,早期植入的幼儿大脑仍然有可能比成人的适应性更强,能够在一定程度上克服该设备的局限性。该项目的目标是: i) 测量听力正常的学龄儿童和植入人工耳蜗的儿童对音调变化的心理物理敏感性; ii) 当音高下降时,量化儿童使用不同声学线索处理语音语调和词汇声调的能力; iii) 量化人工耳蜗植入儿童在类似任务中的表现。这些研究的结果将为幼儿对音调线索的敏感性、人工耳蜗植入如何影响这种敏感性以及早期植入的听觉系统可以在多大程度上克服假体的重要限制提供重要的新线索。
公共卫生相关性:日常言语中音调的自然变化传达了重要的语言信息,对于幼儿和儿童的语言学习尤其重要。人们对幼儿对音调的敏感性知之甚少,而接受人工耳蜗植入的重度听力损失儿童在音调信息方面处于特别不利的地位。本研究的结果将揭示听力正常和植入人工耳蜗的儿童从 6 岁到成年早期的音调处理的基本机制。
