The impact of cognitive ability on multitalker speech perception in neurodivergent individuals
收藏资源简介：
This is a behavioral dataset obtained from 49 human participants from 3 different groups: autism, fetal alcohol spectrum disorder, age- and sex-matched comparison group. The datafile contains multitalker speech perception thresholds across 4 separate runs, as well as performance on the Wescler Abbreviated Scale of Intelligence, 2nd Edition., , # The impact of cognitive ability on multitalker speech perception in neurodivergent individuals Dataset DOI: [10.5061/dryad.5mkkwh7hp](10.5061/dryad.5mkkwh7hp) ## Description of the data and file structure In this study, we investigated the relationship between intellectual ability and speech perception under noisy multi-talker conditions. We tested individuals with autism, fetal alcohol spectrum disorder, and an age- and sex-matched comparison group, all with typical hearing. We found a strong positive correlation between IQ and multitalker speech perception thresholds. This data file contains speech perception thresholds across 4 runs as well as performance on the Wechsler Abbreviated Scale of Intelligence, 2nd Edition. Please contact Bonnie Lau, [blau@uw.edu](mailto:blau@uw.edu) for further information. ### Files and variables #### File: Lau_etal_2025_CRMSentences_datafile.csv **Description:** ##### Variables * Sex * Group * Age at testing reported in age bins * Speech ..., Consent from participants was obtained to publish de-identified data in the public domain.
