How auditory processing influences the autistic profile: A review / R. POULSEN in Autism Research, 17-12 (December 2024)

This sensory data helps us understand our surroundings, influencing our experiences and interactions within our everyday environments. Recent interest in sensory-focused approaches to supporting autistic people has fixed on auditory processing?the sense of hearing and the act of listening?and its crucial role in language, communications, and social domains, as well as non-social autism-specific attributes, to understand better how sensory processing might differ in autistic people. In this narrative review, we synthesize published research into auditory processing in autistic people and the relationship between auditory processing and autistic attributes in a contextually novel way. The purpose is to understand the relationship between these domains more fully, drawing on evidence gleaned from experiential perspectives through to neurological investigations. We also examine the relationship between auditory processing and diagnosable auditory conditions, such as hyperacusis, misophonia, phonophobia, and intolerance to loud sounds, as well as its relation to sleep, anxiety, and sensory overload. Through reviewing experiential, behavioral and neurological literature, we demonstrate that auditory processes interact with and shape the broader autistic profile?something not previously considered. Through a better understanding of the potential impact of auditory experiences, our review aims to inform future research on investigating the relationship between auditory processing and autistic traits through quantitative measures or using qualitative experiential inquiry to examine this relationship more holistically.

Reduced auditory steady state responses in autism spectrum disorder / R. A. SEYMOUR in Molecular Autism, 11 (2020)  

Public ISBD [article]  inMolecular Autism > 11 (2020) . - 56 p. Titre : Reduced auditory steady state responses in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : R. A. SEYMOUR, Auteur ; G. RIPPON, Auteur ; G. GOODING-WILLIAMS, Auteur ; P. F. SOWMAN, Auteur ; K. KESSLER, Auteur Article en page(s) : 56 p. Langues : Anglais (eng) Mots-clés : Auditory steady state  Autism spectrum disorder  Gamma  Meg  Sensory Index. décimale : PER Périodiques Résumé : BACKGROUND: Auditory steady state responses (ASSRs) are elicited by clicktrains or amplitude-modulated tones, which entrain auditory cortex at their specific modulation rate. Previous research has reported reductions in ASSRs at 40?Hz for autism spectrum disorder (ASD) participants and first-degree relatives of people diagnosed with ASD (Mol Autism. 2011;2:11, Biol Psychiatry. 2007;62:192-197). METHODS: Using a 1.5?s-long auditory clicktrain stimulus, designed to elicit an ASSR at 40?Hz, this study attempted to replicate and extend these findings. Magnetencephalography (MEG) data were collected from 18 adolescent ASD participants and 18 typically developing controls. RESULTS: The ASSR localised to bilateral primary auditory regions. Regions of interest were thus defined in left and right primary auditory cortex (A1). While the transient gamma-band response (tGBR) from 0-0.1?s following presentation of the clicktrain stimulus was not different between groups, for either left or right A1, the ASD group had reduced oscillatory power at 40?Hz from 0.5 to 1.5?s post-stimulus onset, for both left and right A1. Additionally, the ASD group had reduced inter-trial coherence (phase consistency over trials) at 40?Hz from 0.64-0.82?s for right A1 and 1.04-1.22?s for left A1. LIMITATIONS: In this study, we did not conduct a clinical autism assessment (e.g. the ADOS), and therefore, it remains unclear whether ASSR power and/or ITC are associated with the clinical symptoms of ASD. CONCLUSION: Overall, our results support a specific reduction in ASSR oscillatory power and inter-trial coherence in ASD, rather than a generalised deficit in gamma-band responses. We argue that this could reflect a developmentally relevant reduction in non-linear neural processing.
