The purpose of this study is to understand how children's brains process sounds and language. Children with Autism Spectrum Disorder (ASD), Intellectual and Developmental Delay (IDD), or Developmental Language Disorder (DLD) often have trouble understanding sounds that are too close together compared to Typically Developing Controls (children without ASD, IDD, or DLD). Fast changes in speech can be hard for children. This may be awkward during conversations and difficult in social situations. This research will see if trouble with processing sounds contributes to language difficulties in children with ASD, IDD, and/or DLD.
