About this trial
The goal of this study is to identify which brain regions are active during speech-in-noise perception, as well as how those regions interact. The investigators are studying brain activation during speech-in-noise in autism and controls as well as individuals with Fragile X Syndrome. The main question\[s\] it aims to answer are: 1) How does the brain's response to background noise affect a person's ability to understand speech? 2) Can visual cues improve hearing in background noise?
Participants will complete the following:
* hearing tests * cognitive and behavioral measures * questionnaires about their symptoms * both passive and active hearing tasks while brain activity is recorded with a neuroimaging cap Results will be compared between individuals with autism with and without Fragile X Syndrome as well as individuals without autism.
