Effective speech-in-noise (SiN) processing relies on auditory processing, which tracks target sounds amidst noise, and semantic processing, which further integrates relevant acoustic information to derive meaning. This study examined these two processes in autism. Thirty-one autistic and 31 non-autistic adults completed a sentence judgment task under three conditions: quiet, babble noise, and competing speech. Auditory processing was measured using EEG-derived temporal response functions (TRFs), which tracked how the brain follows speech sounds, while semantic processing was assessed via behavioral accuracy and the N400 component, a neural marker of semantic processing. Autistic participants showed reduced TRF responses and delayed N400 onset, indicating less efficient auditory processing and slower semantic processing, despite similar N400 amplitude and behavioral performance. Moreover, non-autistic participants demonstrated a trade-off between auditory and semantic processing resources. In the competing speech condition, they showed enhanced semantic integration but reduced neural tracking of auditory information when managing linguistic competition introduced by intelligible speech noise. In contrast, the autistic group showed no modulation of neural responses, suggesting reduced flexibility in adjusting auditory and semantic demands. These findings highlight distinct neural processing patterns in autistic individuals during SiN tasks, providing new insights into how atypical auditory and semantic processing shape SiN perception in autism.

Linguistic and Musical Syntax Processing in Autistic and Non-Autistic Individuals: An Event-Related Potential (ERP) Study / Anna PETROVA ; Zivile BERNOTAITE ; Maleeha SUJAWAL ; Chen ZHAO ; Hiba AHMED ; Cunmei JIANG ; Fang LIU in Autism Research, 18-6 (June 2025)

The Shared Syntactic Integration Resource Hypothesis (SSIRH) was introduced based on observations of similar neural responses to syntactic violations across both domains. This hypothesis suggests that difficulties in syntactic processing in one domain may result in similar challenges in the other. The current study tested the SSIRH in autism, a neurodevelopmental condition often associated with language difficulties but relatively preserved musical abilities. Thirty-one autistic and 31 non-autistic participants judged the acceptability of syntactically congruent and incongruent sentences and musical sequences while their neural responses were recorded using electroencephalography. Autistic participants exhibited a reduced and delayed P600 effect?a marker of syntactic integration across both domains, despite achieving similar behavioral accuracy to the non-autistic group. These findings suggest parallel difficulties in syntactic processing in autism for both language and music, providing support for the SSIRH. This is the first study to directly examine real-time syntactic integration in both domains in autistic individuals, offering novel insights into cross-domain syntactic processing in autism and contributing to a deeper understanding of language and music processing more broadly.
