Multisensory integration of naturalistic speech and gestures in autistic adults Matyjek, Magdalena Kita, Sotaro Torralba Cuello, Mireia Soto-Faraco, Salvador, 1970- Audio-visual speech Autism EEG Iconic gestures Multisensory integration Seeing the speaker often facilitates auditory speech comprehension through audio-visual integration. This audio-visual facilitation is stronger under challenging listening conditions, such as in real-life social environments. Autism has been associated with atypicalities in integrating audio-visual information, potentially underlying social difficulties in this population. The present study investigated multisensory integration (MSI) of audio-visual speech information among autistic and neurotypical adults. Participants performed a speech-in-noise task in a realistic multispeaker social scenario with audio-visual, auditory, or visual trials while their brain activity was recorded using EEG. The neurotypical group demonstrated a non-linear audio-visual effect in alpha oscillations, whereas the autistic group showed merely additive processing. Despite these differences in neural correlates, both groups achieved similar behavioral audio-visual facilitation outcomes. These findings suggest that although autistic and neurotypical brains might process multisensory cues differently, they achieve comparable benefits from audio-visual speech. These results contribute to the growing body of literature on MSI atypicalities in autism.
