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）：培训提出的培训支持了PI的新翻译研究计划的目标，该计划将重点介绍与CIS和成人CIS和成人的声音隔离和音乐感知能力有关的问题。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，以测试听众的能力，以使用基于频率的线索将相关性与无关的声音分开。这些非语音措施有望增加我们对语言独立过程如何促进CIS性能中观察到的巨大个体差异的有限理解，并有助于指导新的刺激加工或关联策略，以提高音乐感知。该方法很容易扩展到其他类型的刺激，包括语音模式和背景。第一个具体目的是确定年轻的正常听觉（NH）儿童使用模式/背景跨模式识别的基于频率的线索的能力，并在有或没有CL模拟的情况下。第二个具体目的是使用这些相同的刺激来表征CIS成人的表现。最终的目的是使用这些早期研究中所学的知识来最佳检查CI的幼儿的模式识别，这是PI未来研究计划的预期重点。在完成这些目标的过程中，PI将在该领域获得竞争性R21或R01应用的必要知识，技能和数据。
