DESCRIPTION (provided by applicant): The training proposed supports the objective of a new translational research program for the PI that will focus on issues related to sound-segregation and music perception abilities of children and adults with CIs. The proposed experiments use new pattern-identification tasks in quiet and with various background sounds to test listeners' abilities to use frequency-based cues to separate relevant from irrelevant sounds. These non-speech measures are expected to increase our limited understanding of how language-independent processes contribute to the large individual differences observed in performance with CIs, and help guide new stimulus-processing or habilitation strategies to improve music perception. The approach can readily be extended to other types of stimuli, including speech patterns and backgrounds. The first specific aim is to determine the ability of young normal-hearing (NH) children to use frequency-based cues across pattern/background to aid pattern identification, with and without Cl simulations. The second specific aim is to use these same stimuli to characterize performance in adults with CIs. The final aim is to use what is learned in these earlier studies to optimally examine pattern identification in young children with CIs, the intended focus of the PI's future research program. In the course of completing these aims, the PI will acquire the necessary knowledge, skills, and data for a competitive R21 or R01 application in this area.

描述（由申请人提供）：拟议的培训支持 PI 的新转化研究计划的目标，该计划将重点关注与 CI 儿童和成人的声音隔离和音乐感知能力相关的问题。所提出的实验在安静和各种背景声音中使用新的模式识别任务来测试听众使用基于频率的线索来区分相关声音和不相关声音的能力。这些非言语测量预计将增加我们对独立于语言的过程如何导致在 CI 表现中观察到的巨大个体差异的有限理解，并帮助指导新的刺激处理或适应策略以改善音乐感知。该方法可以很容易地扩展到其他类型的刺激，包括语音模式和背景。第一个具体目标是确定年轻的正常听力 (NH) 儿童在有或没有 Cl 模拟的情况下使用跨模式/背景的基于频率的线索来帮助模式识别的能力。第二个具体目标是使用这些相同的刺激来表征患有 CI 的成年人的表现。最终目标是利用这些早期研究中学到的知识来最佳地检查患有 CI 的幼儿的模式识别，这也是 PI 未来研究计划的预期重点。在完成这些目标的过程中，PI 将获得该领域具有竞争力的 R21 或 R01 应用所需的知识、技能和数据。
