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…

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…

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…

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…

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…

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…

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…

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…

Schulz, S. E.; Stevenson, R. A. – Journal of Autism and Developmental Disorders, 2022
Sensory issues are highly prevalent in autism and previous findings support a relationship between questionnaires of sensitivity and autistic symptoms and traits, whereas studies that examine this relationship through behavioural assessments of sensitivity are less consistent. The current study explores these differences and suggests that…

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…

Scheerer, Nichole E.; Boucher, Troy Q.; Bahmei, Behnaz; Iarocci, Grace; Arzanpour, Siamak; Birmingham, Elina – Journal of Autism and Developmental Disorders, 2022
Decreased sound tolerance (DST) is the most common sensory difficulty experienced by autistic individuals. Parents of 88 autistic children and young adults between the ages of 3 and 30 described coping strategies and physical and emotional responses used to deal with distressing sounds, and their impact on daily activities. Loud, sudden, and…

Feldman, Jacob I.; Conrad, Julie G.; Kuang, Wayne; Tu, Alexander; Liu, Yupeng; Simon, David M.; Wallace, Mark T.; Woynaroski, Tiffany G. – Journal of Autism and Developmental Disorders, 2022
Children with autism show alterations in multisensory integration that have been theoretically and empirically linked with the core and related features of autism. It is unclear, however, to what extent multisensory integration maps onto features of autism within children with and without autism. This study, thus, evaluates relations between…

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…

Emmons, Katherine A.; K. C. Lee, Adrian; Estes, Annette; Dager, Stephen; Larson, Eric; McCloy, Daniel R.; St. John, Tanya; Lau, Bonnie K. – Journal of Autism and Developmental Disorders, 2022
Difficulty listening in noisy environments is a common complaint of individuals with autism spectrum disorder (ASD). However, the mechanisms underlying such auditory processing challenges are unknown. This preliminary study investigated auditory attention deployment in adults with ASD. Participants were instructed to maintain or switch attention…
