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…

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…

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…

Bacon, Alex; Beaman, C. Philip; Liu, Fang – Journal of Autism and Developmental Disorders, 2020
Individuals with autism spectrum disorder (ASD) reportedly possess preserved or superior music-processing skills compared to their typically developing counterparts. We examined auditory imagery and earworms (tunes that get "stuck" in the head) in adults with ASD and controls. Both groups completed a short earworm questionnaire together…

Lau, Joseph C. Y.; To, Carol K. S.; Kwan, Judy S. K.; Kang, Xin; Losh, Molly; Wong, Patrick C. M. – Journal of Autism and Developmental Disorders, 2021
Atypical pitch processing is a feature of Autism Spectrum Disorder (ASD), which affects non-tone language speakers' communication. Lifelong auditory experience has been demonstrated to modify genetically-predisposed risks for pitch processing. We examined individuals with ASD to test the hypothesis that lifelong auditory experience in tone…

Keehn, Brandon; Westerfield, Marissa; Townsend, Jeanne – Journal of Autism and Developmental Disorders, 2019
This study investigates how task-irrelevant auditory information is processed in children with autism spectrum disorder (ASD). Eighteen children with ASD and 19 age- and IQ-matched typically developing (TD) children were presented with semantically-congruent and incongruent picture-sound pairs, and in separate tasks were instructed to attend to…

Bouvet, Lucie; Mottron, Laurent; Valdois, Sylviane; Donnadieu, Sophie – Journal of Autism and Developmental Disorders, 2016
Auditory stream segregation allows us to organize our sound environment, by focusing on specific information and ignoring what is unimportant. One previous study reported difficulty in stream segregation ability in children with Asperger syndrome. In order to investigate this question further, we used an interleaved melody recognition task with…

Boets, Bart; Verhoeven, Judith; Wouters, Jan; Steyaert, Jean – Journal of Autism and Developmental Disorders, 2015
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)…

Mayer, Jennifer L.; Hannent, Ian; Heaton, Pamela F. – Journal of Autism and Developmental Disorders, 2016
Whilst enhanced perception has been widely reported in individuals with Autism Spectrum Disorders (ASDs), relatively little is known about the developmental trajectory and impact of atypical auditory processing on speech perception in intellectually high-functioning adults with ASD. This paper presents data on perception of complex tones and…

Brock, Jon; Bzishvili, Samantha; Reid, Melanie; Hautus, Michael; Johnson, Blake W. – Journal of Autism and Developmental Disorders, 2013
Atypical auditory perception is a widely recognised but poorly understood feature of autism. In the current study, we used magnetoencephalography to measure the brain responses of 10 autistic children as they listened passively to dichotic pitch stimuli, in which an illusory tone is generated by sub-millisecond inter-aural timing differences in…

Williams, Diane L.; Goldstein, Gerald; Minshew, Nancy J. – Journal of Autism and Developmental Disorders, 2013
This study used the modality shift experiment, a relatively simple reaction time measure to visual and auditory stimuli, to examine attentional shifting within and across modalities in 33 children and 42 adults with high-functioning autism as compared to matched numbers of age- and ability-matched typical controls. An exaggerated "modality shift…

Schleicher, Axel; Morosan, Patricia; Amunts, Katrin; Zilles, Karl – Journal of Autism and Developmental Disorders, 2009
Results from functional imaging studies are often still interpreted using the classical architectonic brain maps of Brodmann and his successors. One obvious weakness in traditional, architectural mapping is the subjective nature of localizing borders between cortical areas by means of a purely visual, microscopical examination of histological…

Groen, Wouter B.; van Orsouw, Linda; ter Huurne, Niels; Swinkels, Sophie; van der Gaag, Rutger-Jan; Buitelaar, Jan K.; Zwiers, Marcel P. – Journal of Autism and Developmental Disorders, 2009
The perceptual pattern in autism has been related to either a specific localized processing deficit or a pathway-independent, complexity-specific anomaly. We examined auditory perception in autism using an auditory disembedding task that required spectral and temporal integration. 23 children with high-functioning-autism and 23 matched controls…

Jeste, Shafali S.; Nelson, Charles A., III – Journal of Autism and Developmental Disorders, 2009
In this paper we critically review the literature on the use of event related potentials (ERPs) to elucidate the neural sources of the core deficits in autism. We review auditory and visual ERP studies, and then review the use of ERPs in the investigation of executive function. We conclude that, in autism, impairments likely exist in both low and…

Groen, Wouter B.; van Orsouw, Linda; Zwiers, Marcel; Swinkels, Sophie; van der Gaag, Rutger Jan; Buitelaar, Jan K. – Journal of Autism and Developmental Disorders, 2008
Deficits in the perception of social stimuli may contribute to the characteristic impairments in social interaction in high functioning autism (HFA). Although the cortical processing of voice is abnormal in HFA, it is unclear whether this gives rise to impairments in the perception of voice gender. About 20 children with HFA and 20 matched…
