项目摘要

David Benjamin Ryan completed his doctoral degree in Experimental Psychology December 2014 at East Tennessee State University (ETSU). He has over six years of research experience working primarily in the National Institutes of Health (NIH) funded research laboratory of Eric Sellers Ph. D. During that time he focused on advancing cognitive psychology by utilizing non-invasive methods of the electroencephalogram (EEG) of visual event-related potentials (ERPs) in brain-computer interface (BCI) paradigms. Dr. Ryan’s primary research interests have expanded to include EEG measurements of listening effort. He is currently funded temporarily by the Hearing and Balance Research Program at the Mountain Home Veterans Affairs Medical Center (VAMC) as he works towards establishing his own grant funding. The Career Development Award 1 (CDA-1) would provide Dr. Ryan with the opportunity to develop new research skills and mentoring needed to expand his research interests and to become an independent VA investigator. There are four mentors for this proposal: (1) Sherri Smith, Au. D, Ph.D., is Service Chief of the Audiology and Speech Pathology Service, VA-funded Clinician Investigator, Director of the Audiologic Rehabilitation Laboratory, Mountain Home, and Associate Professor in Department of Audiology and Speech Language Pathology (ASLP) at ETSU, (2) Eric Sellers, Ph. D, Director of the BCI Laboratory and Associate Professor in Psychology at ETSU, (3) Mark Eckert, Ph.D., Associate Professor in Otolaryngology at Medical University of South Carolina, (4) Kim Schairer, Ph. D., Clinician Investigator, Director of the Applied Hearing Research Laboratory at Mountain Home, and Associate Professor in the Department of ASLP at ETSU. Dr. Ryan has proposed a rigorous training plan including coursework, seminars in EEG analysis, hands on training in Bayesian statistics, and travel to conferences for continued professional development and education. The research will be conducted in the Audiologic Rehabilitation Laboratory at Mountain Home, TN VA Medical Center. The Hearing and Balance Research Program has a rich research environment and houses a renowned auditory and vestibular research program with state-of the-art facilities. The broad long-term goal of this research is the development of a clinically relevant measurement of listening effort to improve clinicians’ ability to assess and to formulate a rehabilitation plan for listeners with hearing loss. The goal of the current project is to understand the underlying neurological mechanisms associated with listening effort from which to modify interpretation of current measures or develop a clinically-relevant procedure to measure and quantify an individual’s listening effort during speech perception. This goal will be achieved through three objectives: (1) by examining perceived effort and EEG variables while the listener is engaged in a speech-in-noise task and an auditory working memory task, (2) by examining differences among perceived effort and EEG signals between those with and without hearing loss to determine the effect that hearing loss has on listening effort, and (3) by analyzing the measured variables that will inform development of a clinically-feasible method to assess listening effort in patients with hearing loss.

大卫·本杰明·瑞安在2014年12月完成了他的实验心理学博士学位东田纳西州立大学(ETSU)。他有六年多的研究工作经验。主要在美国国立卫生研究院(NIH)资助的埃里克·塞勒斯博士的研究实验室。在此期间，他专注于通过使用非侵入性的方法来促进认知心理学脑机接口中视觉事件相关电位的脑电研究 (BCI)范式。瑞安博士的主要研究兴趣已经扩展到包括脑电测量倾听的努力。他目前暂时由听力和平衡研究计划资助，网址为山区家庭退伍军人事务医疗中心(VAMC)，因为他正在努力建立自己的拨款。职业发展奖1(CDA-1)将为Ryan博士提供机会培养新的研究技能和指导，以扩大他的研究兴趣并成为一名独立的退伍军人事务部调查员。这项提议有四位导师：(1)澳大利亚的雪莉·史密斯。D，博士，听力学和言语病理科科长，退伍军人事务部资助的临床医生研究员，山间之家听力康复实验室主任，助理 ETSU听力学和言语语言病理学(ASLP)教授，(2)Eric 塞勒斯，博士，BCI实验室主任，ETSU心理学副教授，(3) 马克·埃克特，博士，南卡罗来纳医科大学耳鼻喉科副教授，(4) Kim Schairer博士，临床医生，应用听力研究实验室主任山丘之家，ETSU ASLP系副教授。瑞安博士提出了严格的培训计划，包括课程作业、脑电分析研讨会、贝叶斯实践培训统计，以及参加会议以获得持续的专业发展和教育。这个研究将在田纳西州弗吉尼亚州芒廷豪斯的听力康复实验室进行医疗中心。听力与平衡研究项目拥有丰富的研究环境和拥有一个著名的听觉和前庭研究项目，拥有最先进的设施。《博大》这项研究的长期目标是开发一种与临床相关的听力测量方法努力提高临床医生评估和制定听者康复计划的能力听力损失。目前这个项目的目标是了解潜在的神经机制。与听力工作相关联，由此修改对当前测量的解释或制定与临床相关的程序，用于测量和量化个人在演讲过程中的听力努力感知力。这一目标将通过三个目标来实现：(1)通过检查感知的努力和当听者进行噪声中语音任务和听觉工作记忆时，脑电发生变化任务，(2)通过检查有和有感觉努力和脑电信号之间的差异没有听力损失，以确定听力损失对听力努力的影响，以及(3)通过分析测量的变量，为临床可行的评估方法的发展提供信息听力损失患者的听力努力。
