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…

What Are You Doing with That Object? Comparing the Neural Responses of Action Understanding in Adolescents with and without Autism
Peer reviewed Peer reviewed
Direct linkDirect link
Pokorny, Jennifer J.; Hatt, Naomi V.; Rogers, Sally J.; Rivera, Susan M. – Journal of Autism and Developmental Disorders, 2018
Understanding another's actions, including what they are doing and why they are doing it, can be difficult for individuals with autism spectrum disorder (ASD). This understanding is supported by the action observation (AON) and mentalizing (MZN) networks, as well as the superior temporal sulcus. We examined these areas in children with ASD and…

Keifer, Cara M.; Hauschild, Kathryn M.; Nelson, Brady D.; Hajcak, Greg; Lerner, Matthew D. – Journal of Autism and Developmental Disorders, 2019
Despite evidence suggesting differences in early event-related potential (ERP) responses to social emotional stimuli, little is known about later stage ERP contributions to social emotional processing in individuals with autism spectrum disorder (ASD). Adults with and without ASD completed a facial emotion recognition task involving stimuli that…

Postural and Cortical Responses Following Visual Occlusion in Adults with and without ASD
Peer reviewed Peer reviewed
Direct linkDirect link
Goh, Kwang Leng; Morris, Susan; Parsons, Richard; Ring, Alexander; Tan, Tele – Journal of Autism and Developmental Disorders, 2018
Autism is associated with differences in sensory processing and motor coordination. Evidence from electroencephalography suggests individual perturbation evoked response (PER) components represent specific aspects of postural disturbance processing; P1 reflects the detection and N1 reflects the evaluation of postural instability. Despite the…

English, Michael C. W.; Maybery, Murray T.; Visser, Troy A. W. – Journal of Autism and Developmental Disorders, 2017
Previous work shows that doing a continuous performance task (CPT) shifts attentional biases in neurotypical individuals towards global aspects of hierarchical Navon figures by selectively activating right hemisphere regions associated with global processing. The present study examines whether CPT can induce similar modulations of attention in…

Cooper, Rose A.; Plaisted-Grant, Kate C.; Baron-Cohen, Simon; Simons, Jon S. – Journal of Autism and Developmental Disorders, 2016
Studies of reality monitoring (RM) often implicate medial prefrontal cortex (mPFC) in distinguishing internal and external information, a region linked to autism-related deficits in social and self-referential information processing, executive function, and memory. This study used two RM conditions (self-other; perceived-imagined) to investigate…

Brief Report: Simulations Suggest Heterogeneous Category Learning and Generalization in Children with Autism Is a Result of Idiosyncratic Perceptual Transformations
Peer reviewed Peer reviewed
Direct linkDirect link
Mercado, Eduardo, III; Church, Barbara A. – Journal of Autism and Developmental Disorders, 2016
Children with autism spectrum disorder (ASD) sometimes have difficulties learning categories. Past computational work suggests that such deficits may result from atypical representations in cortical maps. Here we use neural networks to show that idiosyncratic transformations of inputs can result in the formation of feature maps that impair…

Lortie, Melissa; Proulx-Bégin, Léa; Saint-Amour, Dave; Cousineau, Dominique; Théoret, Hugo; Lepage, Jean-François – Journal of Autism and Developmental Disorders, 2017
There is debate whether social impairments in autism spectrum disorder (ASD) are truly domain-specific, or if they reflect generalized deficits in lower-level cognitive processes. To solve this issue, we used auditory-evoked EEG responses to assess novelty detection (MMN component) and involuntary attentional orientation (P3 component) induced by…
