Project Summary: Cochlear implants (CIs) are an effective treatment for adults with severe-to-profound sensorineural hearing loss, and ideally lead to improved real-world communication skills and social engagement. However, we currently do not have a good understanding of relevant, modifiable factors that contribute to the enormous variability in communication outcomes observed in both new and experienced CI users. Further, the current method by which we quantify CI outcomes, via clinical measures of speech recognition, tells us little about the real-world functioning of our CI patients. Our long-term goal is to better understand real-world communication, learning, and adaptation in adult CI users, and the sensory and cognitive-linguistic processes that support maximizing real-world CI benefits, in order to identify future targets for rehabilitative efforts. New CI users largely learn to adapt to their CIs through their everyday experiences. Differences in the real-world auditory- social experience of new CI users likely contribute to communication outcomes, but currently our knowledge of how real-world experience promotes adaptation in adult CI users is limited. Further, the extent to which auditory- social experience changes following implantation remains unclear. Therefore, the overall objectives of the proposed research are to determine how diverse auditory-social experience facilitates speech recognition abilities in new CI users, and to characterize changes in their auditory-social experience, using a multi- disciplinary approach. Here, we focus on the amount and variability of new CI users’ speech input (“speech input attributes”), through assessment of their social networks and communication practices. Our central hypothesis is that speech input variability experienced in the real-world auditory-social environment promotes robust speech recognition abilities in new CI users, and that access to diverse real-world auditory-social experience expands as a benefit of implantation. Our hypothesis will be tested in two Specific Aims: Aim 1 will determine the contribution of speech input attributes experienced in the real-world auditory-social environment to robust speech recognition abilities in new CI users. We will assess the association between new CI users’ experience of speech input variability and amount and speech recognition abilities in challenging conditions, pre- operatively and over 6 months of CI use. Aim 2 will investigate changes in the real-world auditory-social experience of new CI users following implantation, and the moderating role of robust communication skills. We will compare speech input attributes pre-operatively and at 6 months of CI use, and evaluate the relation between changes and speech comprehension ability. The proposed research will lead to a better understanding of modifiable factors (i.e. auditory-social environments) that best support adaptation and will help to define real- world social engagement benefits of implantation. Findings will provide a scientific basis for the development of new rehabilitation protocols and clinical assessment tools to optimize real-world outcomes in CI patients.

项目概要： 耳蜗植入物（CI）是严重至极重度感音神经性听力损失成人的有效治疗方法， 理想情况下，这将提高现实世界的沟通技巧和社会参与度。然而，我们目前 没有很好地理解相关的、可修改的因素，这些因素导致了 在新的和有经验的CI用户中观察到的沟通结果。此外，目前的方法， 我们通过语音识别的临床测量来量化CI结果， 我们的CI患者的功能我们的长期目标是更好地理解现实世界的沟通，学习， 和适应在成年CI用户，以及感官和认知语言的过程，支持 最大化现实世界的CI效益，以确定未来的康复目标。新CI用户 很大程度上是通过他们的日常经验来适应他们的CI。在现实世界中的听觉差异- 新CI用户的社会经验可能有助于沟通结果，但目前我们对 现实世界的经验如何促进成人CI用户的适应是有限的。此外，听觉- 植入后的社会经验变化仍不清楚。因此， 建议的研究是确定不同的社交经验如何促进语音识别 新的CI用户的能力，并描述他们的社交经验的变化，使用多 纪律性的方法。在这里，我们关注新CI用户的语音输入（“语音输入”）的数量和变化 属性”），通过评估他们的社交网络和通信实践。我们的核心假设 在真实世界的社交环境中经历的语音输入可变性促进了鲁棒语音 新的CI用户的识别能力，以及获得多样化的现实世界的社交经验扩展 作为植入的好处。我们的假设将在两个具体目标中得到检验：目标1将决定 在真实世界的语音-社会环境中经历的语音输入属性对鲁棒语音的贡献 新用户的认知能力。我们将评估新CI用户的体验与 语音输入的可变性和数量以及在具有挑战性的条件下的语音识别能力， 手术和超过6个月的CI使用。目标2将调查现实世界中的社会性变化 植入后新CI用户的经验，以及强大的沟通技能的调节作用。我们 将比较术前和CI使用6个月时的语音输入属性，并评估 变化和言语理解能力之间的关系。拟议的研究将导致更好地了解 最能支持适应并将有助于界定真实的的可改变因素（即宗教-社会环境） 世界社会参与植入的好处。研究结果将为开发 新的康复方案和临床评估工具，以优化CI患者的实际结果。
