Auditory processing in autism spectrum disorder: Mismatch negativity deficits / Chantal VLASKAMP in Autism Research, 10-11 (November 2017)  

Public ISBD [article]  inAutism Research > 10-11 (November 2017) . - p.1857-1865 Titre : Auditory processing in autism spectrum disorder: Mismatch negativity deficits Type de document : texte imprimé Auteurs : Chantal VLASKAMP, Auteur ; Bob ORANJE, Auteur ; Gitte Falcher MADSEN, Auteur ; Jens Richardt MØLLEGAARD JEPSEN, Auteur ; Sarah DURSTON, Auteur ; Cathriona CANTIO, Auteur ; Birte GLENTHØJ, Auteur ; Niels BILENBERG, Auteur Article en page(s) : p.1857-1865 Langues : Anglais (eng) Mots-clés : auditory processing  ASD  MMN  P3a  schizophrenia Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorders (ASD) often show changes in (automatic) auditory processing. Electrophysiology provides a method to study auditory processing, by investigating event-related potentials such as mismatch negativity (MMN) and P3a-amplitude. However, findings on MMN in autism are highly inconsistent, partly due to small sample sizes in the studies and differences in MMN paradigms. Therefore, in the current study, MMN and P3a amplitude were assessed in a relatively large sample of children with ASD, using a more extensive MMN paradigm and compared with that of typically developing children (TDC). Thirty-five children (aged 8–12 years) with ASD and 38 age and gender matched TDC were assessed with a MMN paradigm with three types of deviants, i.e., frequency, duration and a combination of these two. MMN elicited by duration and frequency-duration deviants was significantly reduced in the ASD group. P3a-amplitude elicited by duration deviants was significantly increased in the ASD group. Reduced MMN in children with ASD suggests that children with ASD may be less responsive to environmentally deviant stimuli at an early (sensory) level. P3a-amplitude was increased in ASD, implying a hyper-responsivity at the attentional level. In addition, as similar MMN deficits are found in schizophrenia, these MMN results may explain some of the frequently reported increased risk of children with ASD to develop schizophrenia later in life. Autism Res 2017, 10: 1857–1865. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary Automatic detection of deviant sounds in the environment, such as upcoming traffic, is often affected in children with autism spectrum disorders (ASD). Mismatch negativity (MMN) is a way to quantify automatic deviancy detection, using electroencephalography. In this study, auditory MMN was assessed in 35 children with ASD and 38 matched control children, revealing significantly reduced MMN in the ASD group. This may indicate that children with ASD are less able to automatically detect environmentally deviant stimuli.

Autistic Children With Speech Onset Delay Show Reversed Bias in Spectral Versus Temporal Auditory Processing / Luodi YU in Autism Research, 19-6 (June 2026)  

Public ISBD [article]  inAutism Research > 19-6 (June 2026) . - p.e70248 Titre : Autistic Children With Speech Onset Delay Show Reversed Bias in Spectral Versus Temporal Auditory Processing Type de document : texte imprimé Auteurs : Luodi YU, Auteur ; Shuyu XIE, Auteur ; Li WANG, Auteur ; Laurent MOTTRON, Auteur Article en page(s) : p.e70248 Langues : Anglais (eng) Mots-clés : auditory processing  autism  language  spectral processing  temporal processing Index. décimale : PER Périodiques Résumé : ABSTRACT A recent ?hierarchical? reinterpretation of the neurological basis of autism suggests that in autism with early language delay, perceptual processing may be favored over the integration of transmodal information. This model is largely based on neuroimaging findings relating to visual processing, but predicts a corresponding reorganization in the auditory modality. The present study provides the first direct psychophysical evidence of a reversed auditory processing bias in children with prototypical autism, characterized by impaired temporal resolution and enhanced spectral sensitivity. Using two matched psychoacoustic paradigms?temporal gap detection and low-frequency frequency modulation (FM) detection?we assessed auditory thresholds in 21 autistic and 23 typically developing (TD) children. Compared to TD peers, autistic children exhibited significantly higher temporal thresholds and significantly lower spectral thresholds, yielding a markedly elevated Auditory Bias Index (ABI) that quantifies a preference for spectral over temporal cues. In the group of autistic children investigated here, enhanced spectral resolution correlated positively with receptive language and nonverbal IQ, whereas temporal resolution was associated with age-related gains and language outcomes. These findings support the hypothesis of an atypical sensory-perceptual hierarchy in autism with speech onset delay and early behavioral atypicalities, with potential implications for alternative, nonsocial pathways to language acquisition.

Early differences in auditory processing relate to Autism Spectrum Disorder traits in infants with Neurofibromatosis Type I / Jannath BEGUM-ALI in Journal of Neurodevelopmental Disorders, 13 (2021)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 13 (2021) Titre : Early differences in auditory processing relate to Autism Spectrum Disorder traits in infants with Neurofibromatosis Type I Type de document : texte imprimé Auteurs : Jannath BEGUM-ALI, Auteur ; Anna KOLESNIK-TAYLOR, Auteur ; Isabel QUIROZ, Auteur ; Luke MASON, Auteur ; Shruti GARG, Auteur ; Jonathan GREEN, Auteur ; Mark H.

Positing a causal role for sensory processing differences requires observing atypical sensory reactivity prior to the emergence of other symptoms, which can be achieved through prospective studies. METHODS: In this longitudinal study, we examined auditory repetition suppression and change detection at 5 and 10 months in infants with and without Neurofibromatosis Type 1 (NF1), a condition associated with higher likelihood of developing ASD. RESULTS: In typically developing infants, suppression to vowel repetition and enhanced responses to vowel/pitch change decreased with age over posterior regions, becoming more frontally specific; age-related change was diminished in the NF1 group. Whilst both groups detected changes in vowel and pitch, the NF1 group were largely slower to show a differentiated neural response. Auditory responses did not relate to later language, but were related to later ASD traits. CONCLUSIONS: These findings represent the first demonstration of atypical brain responses to sounds in infants with NF1 and suggest they may relate to the likelihood of later ASD.

Fragile Spectral and Temporal Auditory Processing in Adolescents with Autism Spectrum Disorder and Early Language Delay / Bart BOETS in Journal of Autism and Developmental Disorders, 45-6 (June 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-6 (June 2015) . - p.1845-1857 Titre : Fragile Spectral and Temporal Auditory Processing in Adolescents with Autism Spectrum Disorder and Early Language Delay Type de document : texte imprimé Auteurs : Bart BOETS, Auteur ; Judith VERHOEVEN, Auteur ; Jan WOUTERS, Auteur ; Jean STEYAERT, Auteur Article en page(s) : p.1845-1857 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Auditory processing  Hemispheric lateralization  Spectral  Temporal  Pitch Index. décimale : PER Périodiques Résumé : We investigated low-level auditory spectral and temporal processing in adolescents with autism spectrum disorder (ASD) and early language delay compared to matched typically developing controls. Auditory measures were designed to target right versus left auditory cortex processing (i.e. frequency discrimination and slow amplitude modulation (AM) detection versus gap-in-noise detection and faster AM detection), and to pinpoint the task and stimulus characteristics underlying putative superior spectral processing in ASD. We observed impaired frequency discrimination in the ASD group and suggestive evidence of poorer temporal resolution as indexed by gap-in-noise detection thresholds. These findings question the evidence of enhanced spectral sensitivity in ASD and do not support the hypothesis of superior right and inferior left hemispheric auditory processing in ASD.

How auditory processing influences the autistic profile: A review / Rebecca 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.
