Examining relationship between auditory brainstem responses, cognitive ability, and speech-in-noise perception among young adults with normal hearing thresholds
收藏资源简介：
The goal of this research was to determine the contributions of auditory neural processing and cognitive abilities to predict performance on a competing talker task in young, normal hearing adults. Two experiments were performed, each with separate cohorts of ~30 young adults with normal hearing who performed a competing talker task which included a high-pass filtered condition that was designed to be more sensitive to auditory nerve functioning than are commonly used speech-in-noise perception tests. Predictors of performance on this speech-in-speech task included ABR waves I and V metrics and cognitive test scores. Experiment one included click ABRs at a moderate level commensurate with the level of the competing talker task, as well as the cognitive digit span working memory test. Experiment two included high-intensity click clinical ABRs and three cognitive tests from the NIH Toolbox V3 that assessed working memory, cognitive flexibility and attention, and inhibitory control: List S..., Across two experiments, participants performed a competing talker task, in which they attended to a target talker and ignored a competing talker, and tests of cognitive ability. Auditory brainstem responses (ABRs) were also recorded. From Experiment 1, the dataset contains percent correct on the competing talker task for both the \"Control\" and \"High Pass\" conditions, percent correct on forward and backward digit span, the average digit span percent correct, ABR waves I and V amplitudes and latencies, the ABR wave I:V ratio, and the ABR latency difference between wave I and wave V for each participant. From Experiment 2, the dataset contains percent correct on the competing talker task for the \"High Pass\" condition, normalized scores from the NIH Cognitive Toolbox tests List Sorting Working Memory, Dimensional Change Card Sort, and Flanker Inhibitory Control and Attention, ABR waves I and V amplitudes and latencies, the ABR wave I:V ratio, and the ABR latency difference between wave I an..., , # Examining the relationship between auditory brainstem responses, cognitive ability, and speech-in-noise perception among young adults with normal hearing thresholds [https://doi.org/10.5061/dryad.kprr4xhft](https://doi.org/10.5061/dryad.kprr4xhft) ## Description of the data and file structure Across two experiments, this study examined the relationship between auditory brainstem responses, cognitive ability, and speech-in-noise perception scores among young adults with normal hearing thresholds. ### Files and variables #### File: Experiment1Data.csv **Description:** ##### Variables * ParticipantID: The anonymized identification number of the participant * Control: Percent correct scores from the Control condition of the competing talker task * HighPass: Percent correct scores from the High Pass condition of the competing talker task * ForwardDigitPct: Percent correct scores from the Forward condition of the digit span task * BackwardDigitPct: Percent correct scores from the ...,
本研究旨在明确听觉神经加工与认知能力对正常听力青年完成竞争性言语任务表现的预测作用。本研究共开展两项实验，每项实验均招募约30名正常听力青年作为被试，所有被试均完成竞争性言语任务，该任务包含高通滤波条件，该条件相较于常用的噪声中言语感知测试，对听觉神经功能更为敏感。本研究选取听觉脑干反应（auditory brainstem responses, ABR）的I、V波指标以及认知测试得分作为该言语-言语掩蔽任务表现的预测变量。 实验一采用与竞争性言语任务声级匹配的中等强度短声ABR测试，并施测数字广度工作记忆任务。实验二则采用高强度短声临床ABR测试，以及来自美国国立卫生研究院（National Institutes of Health, NIH）工具箱V3的三项认知测试，分别评估工作记忆、认知灵活性与注意力，以及抑制控制：List S...。 两项实验中，被试均完成竞争性言语任务（即关注目标言语、忽略竞争性言语）以及认知能力测试，同时记录听觉脑干反应（ABR）。 从实验一的数据来看，数据集包含每名被试在竞争性言语任务“对照”与“高通滤波”两种条件下的正确得分率、数字广度正序与倒序任务的正确得分率、数字广度平均正确得分率、ABR I、V波的波幅与潜伏期、ABR I:V波幅比，以及I波与V波的潜伏期差值。 从实验二的数据来看，数据集包含每名被试在竞争性言语任务“高通滤波”条件下的正确得分率、美国国立卫生研究院认知工具箱测试（List Sorting Working Memory、Dimensional Change Card Sort与Flanker Inhibitory Control and Attention）的标准化得分、ABR I、V波的波幅与潜伏期、ABR I:V波幅比，以及I波与V波的潜伏期差值（原文此处有截断）。 # 探究正常听力青年的听觉脑干反应、认知能力与噪声中言语感知的关联 [https://doi.org/10.5061/dryad.kprr4xhft](https://doi.org/10.5061/dryad.kprr4xhft) ## 数据与文件结构说明 本研究通过两项实验，探究正常听力青年的听觉脑干反应、认知能力与噪声中言语感知得分之间的关联。 ### 文件与变量 #### 文件：Experiment1Data.csv **文件说明：** ##### 变量 * ParticipantID：被试的匿名标识编号 * Control：被试在竞争性言语任务“对照”条件下的正确得分率 * HighPass：被试在竞争性言语任务“高通滤波”条件下的正确得分率 * ForwardDigitPct：被试在数字广度正序任务中的正确得分率 * BackwardDigitPct：被试在数字广度倒序任务中的正确得分率（原文此处有截断）
