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.

项目总结： 人工耳蜗术是治疗成人重度至重度感音神经性耳聋的有效方法， 并在理想情况下提高现实世界的沟通技能和社交参与度。然而，我们目前做的是 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，目前使用的方法 我们通过语音识别的临床测量来量化CI结果，这几乎不能告诉我们真实世界的情况 我们的脑梗塞患者的功能。我们的长期目标是更好地了解现实世界的沟通、学习、 成人CI使用者的认知和适应，以及支持 最大限度地扩大现实世界的传播和信息利益，以便确定未来康复努力的目标。新配置项用户 很大程度上是通过他们的日常经历来学习适应他们的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 现实世界的体验如何促进成年CI用户的适应是有限的。此外，听觉的程度- 植入后社会体验的变化仍不清楚。因此，委员会的总体目标是 拟议的研究是为了确定不同的听觉-社会体验如何促进语音识别 新CI用户的能力，并使用多个 纪律处分。在这里，我们关注的是新的CI用户的语音输入的量和变化性 属性“)，通过评估他们的社交网络和沟通做法。我们的中心假设 在真实世界的听觉-社会环境中经历的语音输入的可变性促进了健壮的语音 新CI用户的识别能力，以及获得不同现实世界听觉-社会体验的机会扩大 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 真实世界听觉社会环境中的语音输入属性对健壮语音的贡献 新CI用户的识别能力。我们将评估新的CI用户体验与 在具有挑战性的条件下，语音输入的变异性和数量以及语音识别能力 手术中和超过6个月的CI使用。目标2将调查现实世界中听觉-社会的变化 植入后新CI用户的体验，以及强大的沟通技能的调节作用。我们 将在使用CI前和使用CI的6个月时比较语音输入属性，并评估关系 变化与言语理解能力之间的关系。拟议的研究将使我们更好地理解 可修改的因素(即，听觉-社会环境)最能支持适应，并将有助于定义真实的 植入的世界社会参与的好处。研究结果将为发展 新的康复方案和临床评估工具，以优化脑梗塞患者的现实世界结果。
