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)…

Yu, Luodi; Huang, Dan; Wang, Suiping; Zhang, Yang – Journal of Autism and Developmental Disorders, 2023
Children with autism often show atypical brain lateralization for speech and language processing, however, it is unclear what linguistic component contributes to this phenomenon. Here we measured event-related potential (ERP) responses in 21 school-age autistic children and 25 age-matched neurotypical (NT) peers during listening to word-level…

O'Rourke, Emme; Coderre, Emily L. – Journal of Autism and Developmental Disorders, 2021
While many individuals with autism spectrum disorder (ASD) experience difficulties with language processing, non-linguistic semantic processing may be intact. We examined neural responses to an implicit semantic priming task by comparing N400 responses--an event-related potential related to semantic processing--in response to semantically related…

Siu, Michelle T.; Goodman, Sarah J.; Yellan, Isaac; Butcher, Darci T.; Jangjoo, Maryam; Grafodatskaya, Daria; Rajendram, Rageen; Lou, Youliang; Zhang, Rujun; Zhao, Chunhua; Nicolson, Rob; Georgiades, Stelios; Szatmari, Peter; Scherer, Stephen W.; Roberts, Wendy; Anagnostou, Evdokia; Weksberg, Rosanna – Journal of Autism and Developmental Disorders, 2021
Many neurodevelopmental disorders (NDDs) share common learning and behavioural impairments, as well as features such as dysregulation of the oxytocin hormone. Here, we examined DNA methylation (DNAm) in the 1st intron of the oxytocin receptor gene, "OXTR," in patients with autism spectrum (ASD), attention deficit and hyperactivity (ADHD)…

Raza, Sarah; Sacrey, Lori-Ann R.; Zwaigenbaum, Lonnie; Bryson, Susan; Brian, Jessica; Smith, Isabel M.; Roberts, Wendy; Szatmari, Peter; Vaillancourt, Tracy; Roncadin, Caroline; Garon, Nancy – Journal of Autism and Developmental Disorders, 2020
Social-emotional behavior in autism spectrum disorder (ASD) was examined among high-risk (HR; siblings of children diagnosed with ASD) and low-risk (LR; no family history of ASD) toddlers. Caregivers completed the Infant-Toddler Social Emotional Assessment (ITSEA) at 18 months, and blind diagnostic assessment for ASD was conducted at 36 months.…

Boada, L.; Lahera, G.; Pina-Camacho, L.; Merchán-Naranjo, J.; Díaz-Caneja, C. M.; Bellón, J. M.; Ruiz-Vargas, J. M.; Parellada, M. – Journal of Autism and Developmental Disorders, 2020
Social cognition impairment is a core shared phenotype in both schizophrenia spectrum disorders (SSD) and autism spectrum disorders (ASD). This study compares social cognition performance through four different instruments in a sample of 147 individuals with ASD or SSD and in healthy controls. We found that both clinical groups perform similarly…

Manfredi, Mirella; Cohn, Neil; Sanchez Mello, Pamella; Fernandez, Elizabeth; Boggio, Paulo Sergio – Journal of Autism and Developmental Disorders, 2020
We examined semantic processing in ASD children by presenting sentences with congruent or incongruent final words and visual narratives with congruent or incongruent final panels. An N400 effect to incongruent words appeared as compared to congruent ones, which was attenuated for the ASD children. We observed a negativity sustained to incongruous…

Valeri, Giovanni; Casula, Laura; Napoli, Eleonora; Stievano, Paolo; Trimarco, Barbara; Vicari, Stefano; Scalisi, Teresa Gloria – Journal of Autism and Developmental Disorders, 2020
A novel battery (BAFE; Valeri et al. 2015) was used in order to assess three executive function (EF) abilities (working memory, inhibition and shifting) in a sample of 27 intellectually able preschoolers with autism spectrum disorder (ASD) compared with 27 typically developing children matched on age and nonverbal IQ. Differences in EF skills were…

Cochran, Lisa; Welham, Alice; Oliver, Chris; Arshad, Adam; Moss, Joanna F. – Journal of Autism and Developmental Disorders, 2019
Age-related behavioural change in Cornelia de Lange syndrome is poorly understood. We report a 7 year follow-up study of adaptive behaviour, autism spectrum disorder symptomatology, language skills and behavioural characteristics in 30 individuals with Cornelia de Lange syndrome, compared with 18 individuals with Cri du Chat syndrome. The…

Nilsson Jobs, Elisabeth; Bölte, Sven; Falck-Ytter, Terje – Journal of Autism and Developmental Disorders, 2019
Preschool informants may provide valuable information about symptoms of autism spectrum disorder (ASD) in young children. We compared the diagnostic accuracy of ratings by preschool staff with those by parents of 3-year-old children using the Achenbach System of Empirically Based Assessment Preschool Forms. The sample consisted of 32 children at…

Van der Hallen, Ruth; Chamberlain, Rebecca; de-Wit, Lee; Wagemans, Johan – Journal of Autism and Developmental Disorders, 2018
Since its initial development, the embedded figures test (EFT) has been used extensively to measure local-global perceptual style. However, little is known about the perceptual factors that influence target detection. The current study aimed to investigate "disembedding" in children with and without ASD, aged 8-15 years, using the newly…

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…

Schutte, Claire; Richardson, Wendy; Devlin, Morgan; Hill, Jeanna; Ghossainy, Maliki; Hewitson, Laura – Journal of Autism and Developmental Disorders, 2018
This study investigated categories of autism spectrum disorder (ASD) symptoms measured by the Autism Diagnostic Observation Schedule-Second Edition and their association with maternal stress. Social affect and restricted and repetitive behaviors were compared with levels of maternal stress, measured by the Parenting Stress Index, in 102 children…

Mandy, William; Clarke, Kiri; McKenner, Michele; Strydom, Andre; Crabtree, Jason; Lai, Meng-Chuan; Allison, Carrie; Baron-Cohen, Simon; Skuse, David – Journal of Autism and Developmental Disorders, 2018
We developed a brief, informant-report interview for assessing autism spectrum conditions (ASC) in adults, called the Developmental, Dimensional and Diagnostic Interview-Adult Version (3Di-Adult); and completed a preliminary evaluation. Informant reports were collected for participants with ASC (n = 39), a non-clinical comparison group (n = 29)…

Hartley, Calum; Fisher, Sophie – Journal of Autism and Developmental Disorders, 2018
This study investigated whether children with autism spectrum disorder (ASD) and typically developing children matched on receptive language share resources fairly and reciprocally. Children completed age-appropriate versions of the Ultimatum and Dictator Games with real stickers and an interactive partner. Both groups offered similar numbers of…
