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…

Erin S. M. Matsuba; Beth A. Prieve; Emily Cary; Devon Pacheco; Angela Madrid; Elizabeth McKernan; Elizabeth Kaplan-Kahn; Natalie Russo – Journal of Autism and Developmental Disorders, 2024
This study characterizes the subcortical auditory brainstem response (speech-ABR) and cortical auditory processing (P1 and Mismatch Negativity; MMN) to speech sounds and their relationship to autistic traits and sensory features within the same group of autistic children (n = 10) matched on age and non-verbal IQ to their typically developing (TD)…

Audiovisual Speech Perception in Children with Autism Spectrum Disorders: Evidence from Visual Phonemic Restoration
Peer reviewed Peer reviewed
Direct linkDirect link
Irwin, Julia; Avery, Trey; Kleinman, Daniel; Landi, Nicole – Journal of Autism and Developmental Disorders, 2022
Children with autism spectrum disorders have been reported to be less influenced by a speaker's face during speech perception than those with typically development. To more closely examine these reported differences, a novel visual phonemic restoration paradigm was used to assess neural signatures (event-related potentials [ERPs]) of audiovisual…

Fragile Spectral and Temporal Auditory Processing in Adolescents with Autism Spectrum Disorder and Early Language Delay
Peer reviewed Peer reviewed
Direct linkDirect link
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)…

Perception and Lateralization of Spoken Emotion by Youths with High-Functioning Forms of Autism
Peer reviewed Peer reviewed
Direct linkDirect link
Baker, Kimberly F.; Montgomery, Allen A.; Abramson, Ruth – Journal of Autism and Developmental Disorders, 2010
The perception and the cerebral lateralization of spoken emotions were investigated in children and adolescents with high-functioning forms of autism (HFFA), and age-matched typically developing controls (TDC). A dichotic listening task using nonsense passages was used to investigate the recognition of four emotions: happiness, sadness, anger, and…

Brain Mapping of Language and Auditory Perception in High-Functioning Autistic Adults: A PET Study.
Peer reviewed Peer reviewed
Muller, R-A.; Behen, M. E.; Rothermel, R. D.; Chugani, D. C.; Muzik, O.; Mangner, T. J.; Chugani, H. T. – Journal of Autism and Developmental Disorders, 1999
A study used positron emission tomography (PET) to study patterns of brain activation during auditory processing in five high-functioning adults with autism. Results found that participants showed reversed hemispheric dominance during the verbal auditory stimulation and reduced activation of the auditory cortex and cerebellum. (CR)
