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.

Task-Related Aperiodic EEG (1/f) Activity in Autism / Magdalena MATYJEK in Autism Research, 19-8 (August 2026)  

Public ISBD [article]  inAutism Research > 19-8 (August 2026) . - p.e70314 Titre : Task-Related Aperiodic EEG (1/f) Activity in Autism Type de document : texte imprimé Auteurs : Magdalena MATYJEK, Auteur ; Salvador Soto FARACO, Auteur ; Claudia Alvarez MARTIN, Auteur ; Mireia Torralba CUELLO, Auteur Article en page(s) : p.e70314 Langues : Anglais (eng) Mots-clés : 1/f slope  aperiodic activity  autism  E/I  EEG  excitation/inhibition balance Index. décimale : PER Périodiques Résumé : ABSTRACT Autism has been hypothesized to involve atypicalities in the balance between neural excitation and inhibition (E/I). Aperiodic EEG activity, characterized by the 1/f exponent of the power spectrum, provides a proxy of cortical E/I dynamics. However, prior studies in autism report mixed findings regarding the slope of aperiodic activity. One potentially important modulator of EEG slope is task engagement. Here, we examined variations in aperiodic slopes in autistic (n?=?35) and neurotypical (n?=?39) adults during passive viewing and an active, goal-directed task. The data revealed that autistic participants exhibited steeper slopes (indicative of increased inhibition vs. excitation) during the active task relative to passive viewing, whereas neurotypical participants showed no significant task-related changes. These findings suggest that aperiodic activity reflects dynamic, task-dependent neural adaptation rather than baseline group differences. Task engagement may reveal compensatory inhibitory processes in autistic adults, underscoring the importance of considering task demands and individual variability when investigating E/I balance in autism.
