1 Project Summary / Abstract 2 People with hearing impairment report listening effort as a major barrier to successful social communication 3 (Hughes et al. 2018), with increases in effort leading to increases in anxiety (Morata et al. 2005), early retirement 4 (Danermark & Gellerstedt 2004), changes in social behavior and negative self-image (Hétu et al. 1988), and 5 listening-related fatigue (Edwards, 2007). Fatigued adults have been shown to be less productive in the 6 workplace, with increases in work absences, more errors and accidents than those not suffering from fatigue 7 (Ricci et al. 2007; Williamson et al. 2011), and workers with hearing loss taking more sick leave due to complaints 8 of “mental distress” (Kramer et al., 2006). Therefore, it is critical to understand what aspects of communication 9 are effortful for listeners with hearing impairment, and the ways that sustained effort leads to accumulated mental 10 fatigue. Previous work has mostly examined listening effort and fatigue separately, with vastly different 11 experimental methods and designs, leaving the mechanistic connection between effort and fatigue unknown. 12 This project is designed to address that need by expanding on previous work to explore whether the same 13 mechanisms that contribute to listening effort are merely episodic, or whether they directly contribute to 14 accumulated fatigue. One of the primary mechanisms of listening effort is mentally repairing misperceived words 15 when perceiving speech; using context to retroactively repair earlier misperceptions is effortful (Winn & Teece 16 2021), yet the same context when used predictively can reduce effort (Winn 2016). The aims of this project are 17 to 1) identify how reliance on cognitive repair to recover misperceptions affects listening effort, and 2) directly 18 measure the impact of sustained effortful listening on accumulated fatigue. The first aim will result in identifying 19 the time-course of effort when repairing early versus later misperceived words. Importantly, these results will 20 show how effort is sustained during language processing, potentially for several seconds after sentence offset. 21 The second aim will explore whether momentary increases in effort accumulate to fatigue, which will be 22 measured physiologically (pupillometry) and behaviorally (reaction time). The long-term goals of this project are 23 to improve our understanding of what makes listening effortful for people with CIs and to understand whether 24 the same mechanisms that contribute to listening effort also contribute to fatigue or are merely episodic increases 25 in effort. These goals directly address the NIDCD’s priority of increasing our knowledge of the mechanisms of 26 the cognitive processes needed for successful communication in more real-world environments. The training 27 program involves extensive instruction in behavioral measures, pupillometry, and advanced statistical analysis 28 relevant to the proposed research. This research will be conducted under the mentorship of leading experts in 29 hearing and listening effort, at an institution with a strong track record of hearing loss research, a history of 30 training grants, and interdisciplinary collaboration in clinical sensory science.

1 项目概要/摘要 2 听力障碍人士表示，倾听努力是成功社交沟通的主要障碍 3（Hughes et al. 2018），随着领导努力的增加，焦虑也会增加（Morata et al. 2005），提前退休 4（Danermark & Gellerstedt 2004），社会行为和负面自我形象的变化（Hétu et al. 1988），以及 5 与听力相关的疲劳（Edwards，2007）已证明疲劳的成年人工作效率较低。 6 工作场所，缺勤增加，失误和事故比没有疲劳的人多 7（Ricci et al. 2007；Williamson et al. 2011），听力损失工人因投诉而请更多病假 8 “精神困扰”（Kramer et al., 2006） 因此，了解沟通的哪些方面至关重要。 9 对于有听力障碍的听众来说是努力的，以及持续的努力如何导致积累的心理 10 疲劳。以前的工作大多分别考察听力努力和疲劳，两者差异很大。 11 种实验方法和设计，使努力和疲劳之间的机械联系未知。 12 该项目旨在通过扩展之前的工作来满足这一需求，以确定是否探索相同的 13 种有助于倾听努力的机制只是偶发性的，或者它们是否直接有助于 14 累积的疲劳 听力努力的主要机制之一是在心理上修复误解的单词。 15 当感知言语时，使用上下文来追溯修复早期的错误感知是很困难的（Winn & Teece） 16 2021），但预测性地使用相同的上下文可以减少工作量（Winn 2016）。 17 至 1) 确定依靠认知修复来恢复误解如何影响听力努力，以及 2) 直接 18 衡量持续努力聆听对累积疲劳的影响 第一个目标是确定。 19 修复早期和后期误解的单词所付出的努力的时间过程 重要的是，这些结果将。 图 20 显示了语言处理过程中如何持续努力，可能在句子偏移后持续几秒钟。 21 第二个目标将探讨短暂的努力增加是否会累积成疲劳，这将是 22 生理学（瞳孔测量）和行为学（反应时间）测量 该项目的长期目标是。 23 提高我们对 CI 患者倾听困难的原因的理解，并了解是否 24 有助于听力努力的相同机制也会导致疲劳，或者只是间歇性的增加 25 这些目标直接解决了 NIDCD 增加我们对机制的了解的优先事项。 26 在更真实的环境中成功沟通所需的认知过程。 27 项目涉及行为测量、瞳孔测量和高级统计分析方面的广泛指导 28 与拟议研究相关的这项研究将在领先专家的指导下进行。 29 听力和听力努力，在一个具有良好听力损失研究记录的机构，历史悠久 30 项培训资助以及临床感觉科学方面的跨学科合作。
