"Neural Noise" in Auditory Responses in Young Autistic and Neurotypical Children
Peer reviewed Peer reviewed
Direct linkDirect link
Patrick Dwyer; Svjetlana Vukusic; Zachary J. Williams; Clifford D. Saron; Susan M. Rivera – Journal of Autism and Developmental Disorders, 2024
Elevated "neural noise" has been advanced as an explanation of autism and autistic sensory experiences. However, functional neuroimaging measures of neural noise may be vulnerable to contamination by recording noise. This study explored variability of electrophysiological responses to tones of different intensities in 127 autistic and 79…

The Relationship between Autism and Pitch Perception Is Modulated by Cognitive Abilities
Peer reviewed Peer reviewed

Jia Hoong Ong; Chen Zhao; Alex Bacon; Florence Yik Nam Leung; Anamarija Veic; Li Wang; Cunmei Jiang; Fang Liu – Journal of Autism and Developmental Disorders, 2024
Previous studies reported mixed findings on autistic individuals' pitch perception relative to neurotypical (NT) individuals. We investigated whether this may be partly due to individual differences in cognitive abilities by comparing their performance on various pitch perception tasks on a large sample (n = 164) of autistic and NT children and…

Intact Utilization of Contextual Information in Speech Categorization in Autism
Peer reviewed Peer reviewed

Yafit Gabay; Eva Reinisch; Dana Even; Nahal Binur; Bat-Sheva Hadad – Journal of Autism and Developmental Disorders, 2024
Current theories of Autism Spectrum Disorder (ASD) suggest atypical use of context in ASD, but little is known about how these atypicalities influence speech perception. We examined the influence of contextual information (lexical, spectral, and temporal) on phoneme categorization of people with ASD and in typically developed (TD) people. Across…

Auditory steady-state response (ASSR) has been studied as a potential biomarker for abnormal auditory sensory processing in autism spectrum disorder (ASD), with mixed results. Motivated by prior somatosensory findings of group differences in inter-trial coherence (ITC) between ASD and typically developing (TD) individuals at twice the steady-state…

The Effect of Attention on Auditory Processing in Adults on the Autism Spectrum
Peer reviewed Peer reviewed
Direct linkDirect link
Jewel E. Crasta; Erica C. Jacoby – Journal of Autism and Developmental Disorders, 2024
This study examined the effect of attention on auditory processing in autistic individuals. Electroencephalography data were recorded during two attention conditions (passive and active) from 24 autistic adults and 24 neurotypical controls, ages 17-30 years. The passive condition involved only listening to the clicks and the active condition…

Brief Report: Characterization of Sensory Over-Responsivity in a Broad Neurodevelopmental Concern Cohort Using the Sensory Processing Three Dimensions (SP3D) Assessment

Maia C. Lazerwitz; Mikaela A. Rowe; Kaitlyn J. Trimarchi; Rafael D. Garcia; Robyn Chu; Mary C. Steele; Shalin Parekh; Jamie Wren-Jarvis; Ioanna Bourla; Ian Mark; Elysa J. Marco; Pratik Mukherjee – Journal of Autism and Developmental Disorders, 2024
Sensory Over-Responsivity (SOR) is an increasingly recognized challenge among children with neurodevelopmental concerns (NDC). To investigate, we characterized the incidence of auditory and tactile over-responsivity (AOR, TOR) among 82 children with NDC. We found that 70% of caregivers reported concern for their child's sensory reactions. Direct…

Identification of Native Vowels in Normal and Whispered Speech by Individuals with Autism Spectrum Disorder
Peer reviewed Peer reviewed
Direct linkDirect link
Georgiou, Georgios P. – Journal of Autism and Developmental Disorders, 2023
The present study aims to investigate the identification of native vowel categories by adult individuals with Autism Spectrum Disorder (ASD) and estimate their reaction times in both normal and whisper registers; their responses were compared with those of typically developing individuals. The results demonstrated that there was no deficit for…

Differential Maturation of Auditory Cortex Activity in Young Children with Autism and Typical Development
Peer reviewed Peer reviewed

Green, Heather L.; Shen, Guannan; Franzen, Rose E.; Mcnamee, Marybeth; Berman, Jeffrey I.; Mowad, Theresa G.; Ku, Matthew; Bloy, Luke; Liu, Song; Chen, Yu-Han; Airey, Megan; McBride, Emma; Goldin, Sophia; Dipiero, Marissa A.; Blaskey, Lisa; Kuschner, Emily S.; Kim, Mina; Konka, Kimberly; Roberts, Timothy P. L.; Edgar, J. Christopher – Journal of Autism and Developmental Disorders, 2023
Maturation of auditory cortex neural encoding processes was assessed in children with typical development (TD) and autism. Children 6-9 years old were enrolled at Time 1 (T1), with follow-up data obtained ~ 18 months later at Time 2 (T2), and ~ 36 months later at Time 3 (T3). Findings suggested an initial period of rapid auditory cortex maturation…

The Comprehension of Grammatical Structures in a Pediatric Population with ASD and Epilepsy: A Comparative Study
Peer reviewed Peer reviewed
Direct linkDirect link
Alejandro Cano Villagrasa; Nadia Porcar Gozalbo; Beatriz Valles González; Miguel López-Zamora – Journal of Autism and Developmental Disorders, 2025
Autism Spectrum Disorder (ASD) and epilepsy represent a comorbidity that negatively influences the proper development of linguistic competencies, particularly in receptive language, in the pediatric population. This group displays impairments in the auditory comprehension of both simple and complex grammatical structures, significantly limiting…

Breanne D. Yerkes; Christina M. Vanden Bosch der Nederlanden; Julie F. Beasley; Erin E. Hannon; Joel S. Snyder – Journal of Autism and Developmental Disorders, 2024
Purpose: Processing real-world sounds requires acoustic and higher-order semantic information. We tested the theory that individuals with autism spectrum disorder (ASD) show enhanced processing of acoustic features and impaired processing of semantic information. Methods: We used a change deafness task that required detection of speech and…

Patel, Shivani P.; Winston, Molly; Guilfoyle, Janna; Nicol, Trent; Martin, Gary E.; Nayar, Kritika; Kraus, Nina; Losh, Molly – Journal of Autism and Developmental Disorders, 2023
Efficient neural encoding of sound plays a critical role in speech and language, and when impaired, may have reverberating effects on communication skills. This study investigated disruptions to neural processing of temporal and spectral properties of speech in individuals with ASD and their parents and found evidence of inefficient temporal…

Strong Relationship between Rapid Auditory Processing and Affective Prosody Recognition among Adults with High Autistic Traits
Peer reviewed Peer reviewed
Direct linkDirect link
Lui, Ming; Lau, Gilbert Ka Bo; Han, Yvonne Ming Yee; Yuen, Kevin Chi Pun; Sommer, Werner – Journal of Autism and Developmental Disorders, 2023
This study investigated whether individuals with high autistic traits rely on psychoacoustic abilities in affective prosody recognition (APR). In 94 college students, Autism Spectrum Quotient (AQ) and psychoacoustic abilities were measured. Results indicated that higher AQ, higher rapid auditory processing (RAP), and maleness were associated with…
