![]() With EEG, we can place a cap with small sensors on participants’ head and record their brain’s electrical activity. To capture their response, we used a technology called electroencephalography (EEG). We considered how people with autism not only respond to their name, but how they respond to their name in a context that requires them to filter out other people talking. Spectrum, our team at Boston University’s Center for Autism Research Excellence designed a research study that could be implemented with a wide range of people with autism. To expand our understanding of the brain activity patterns associated with both sound sensitivity and difficulty with language in children and young adults on the autism In particular, we hypothesized that these challenges were more likely in those who, by adolescence, still had not acquired more than minimal spoken language skills. We designed our research to identify whether-subgroups within the autism spectrum were more likely to show signs of a disrupted auditory processing system. Past research has tended to focus on group-level analyses of auditory processing (i.e., comparing people with autism to neurotypical people) but has not looked closely enough at individual differences among people on the autism spectrum. These skills are extremely important when paying attention to, understanding and remembering spoken information, especially in noisy environments. ![]() Effective auditory processing requires the ability to differentiate certain sounds from others and the ability to amplify important sounds while ignoring unimportant ones. They describe a person with autism as having atypical perception and response to sounds, such as feeling overwhelmed by noisy environments or frequently covering one’s ears even when no abrasive noise is present. ![]() Parent- and self-reports collected in multiple studies support the importance of this criteria. About auditory processing in autismĪtypical reaction to sensory input, including sound, is part of one of the core criteria for diagnosing autism. It offers an update on what we’ve learned about the intersection of autism and CAPD from brain imaging research and proposes future steps that are needed to uncover even more answers. Several publications resulted from this fellowship, the most recent of which was published online in August 2020 in the journal Autism Research. I was selected to receive one of these fellowships. In May 2016, Autism Speaks and Royal Arch Masons International announced funding for new fellowships to support research by young investigators to better understand central auditory processing disorders in people with and without autism. However, in several large research studies, roughly 65 percent of parents describe their child with autism as showing sensitivity to noise, while smaller studies report that up to 93 percent of people with autism display atypical responses to sounds, including problems filtering sounds. The reported estimates of the incidence of CAPD in people with autism vary widely by report, in part because there is no “gold-standard” or official way of measuring these disorders. May indicate that certain people who haven’t learned language as expected by adolescence may have trouble detecting differences between speech sounds – a skill that’s fundamental for language acquisition.ĭifficulties processing sounds, often described as central auditory processing disorder or auditory processing disorder (CAPD/APD), are particularly common in people with autism.Participants with autism but with no or only minor language deficits produced early brain responses similar to neurotypical participants.People with autism and more severe language deficits listening to names in a noisy background, including other people talking, did not produce the same early brain responses as shown on brain scans as neurotypical participants, when differentiating the sound of one’s own name from another person’s name.Schwartz received a predoctoral fellowship in 2016 funded by Royal Arch Masons International and Autism Speaks.Ībout CAPD: Central auditory processing disorder, or difficulty processing sounds, is common in people with autism By Sophie Schwartz, Ph.D., post-doctoral research fellow at Boston University’s Center for Autism Research Excellence, directed by Dr.
