Auditory Discrimination in Autism Spectrum Disorder

Auditory Discrimination in Autism Spectrum Disorder

Blog Article

Autism spectrum disorder (ASD) is increasingly common with 1 in 59 children in the United States currently meeting the diagnostic criteria.Altered sensory processing is typical in ASD, with auditory sensitivities being especially common; in particular, people with ASD frequently show heightened sensitivity to environmental sounds and a depileve easy clean poor ability to tolerate loud sounds.These sensitivities may contribute to impairments in language comprehension and to a worsened ability to distinguish relevant sounds from background noise.Event-related potential tests have found that individuals with ASD show altered cortical activity to both simple and speech-like sounds, which likely contribute to the bushranger awning observed processing impairments.Our goal in this review is to provide a description of ASD-related changes to the auditory system and how those changes contribute to the impairments seen in sound discrimination, sound-in-noise performance, and language processing.

In particular, we emphasize how differences in the degree of cortical activation and in temporal processing may contribute to errors in sound discrimination.
