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.
