Examining relationship between auditory brainstem responses, cognitive ability, and speech-in-noise perception among young adults with normal hearing thresholds

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
