Kadlaskar, Girija; Mao, Pin-Hsun; Iosif, Ana-Maria; Amaral, David; Wu Nordahl, Christine; Miller, Meghan – Autism: The International Journal of Research and Practice, 2023
Sensory processing differences are widely reported in autism. However, our understanding of sensory profiles in this population has been complicated due to the heterogeneous presentation of sensory symptoms. We addressed this by using latent profile analysis, allowing for the identification of more homogeneous sensory classes in a large cohort (n…

Brewe, Alexis M.; Simmons, Grace Lee; Capriola-Hall, Nicole N.; White, Susan W. – Autism: The International Journal of Research and Practice, 2020
Adults with autism spectrum disorder often experience co-occurring mental health problems such as attention-deficit/hyperactivity-disorder, as well as impairments in executive function. Sluggish cognitive tempo, a cluster of behaviors including slow processing, daydreaming, and mental fogginess, has been shown to be associated with…

Wylie, Korey P.; Tregellas, Jason R.; Bear, Joshua J.; Legget, Kristina T. – Journal of Autism and Developmental Disorders, 2020
The neurobiology of autism spectrum disorder remains poorly understood. The present study addresses this knowledge gap by examining the relationship between functional brain connectivity and Autism Diagnostic Observation Schedule (ADOS) scores using publicly available data from the Autism Brain Imaging Data Exchange (ABIDE) database (N = 107).…

Mental health problems are prevalent in autistic youth, but the underpinning mechanisms are not well explored. In neurotypical youth, stressful life events are an established risk factor for mental health problems. This study tested longitudinal bidirectional associations between family-level stressful life events and mental health problems and…

Duncan, Amie; Tamm, Leanne; Birnschein, Allison M.; Becker, Stephen P. – Autism: The International Journal of Research and Practice, 2019
Adolescents with autism spectrum disorder frequently experience social communication difficulties, executive functioning deficits, and anxiety and depressive symptoms, which are similar to the symptoms and correlates of sluggish cognitive tempo. Although sluggish cognitive tempo is related to, but distinct from, the inattentive and…

O'Nions, Elizabeth; Sebastian, Catherine L.; McCrory, Eamon; Chantiluke, Kaylita; Happé, Francesca; Viding, Essi – Developmental Science, 2014
Individuals with autism spectrum disorders (ASD) have difficulty understanding other minds (Theory of Mind; ToM), with atypical processing evident at both behavioural and neural levels. Individuals with conduct problems and high levels of callous-unemotional (CU) traits (CP/HCU) exhibit reduced responsiveness to others' emotions and difficulties…

Bolte, Sven; Duketis, Eftichia; Poustka, Fritz; Holtmann, Martin – Autism: The International Journal of Research and Practice, 2011
Despite the skewed sex ratio, few studies have addressed possible cognitive sex differences in autism spectrum disorders (ASDs). This study compared visual attention to detail (ATTD) and selected executive functions (EF) in 35 males and 21 females with higher-functioning ASD and unaffected sibling controls. Females with ASD outperformed males on…

Etemad, Pontea – ProQuest LLC, 2010
The purpose of this study was to examine the relationship between executive functioning (EF), as manifested in everyday behavior, autism spectrum disorder (ASD) symptoms, and adaptive behaviors in a sample of preschoolers with ASD. Quantitative data from a clinical database were analyzed for this study. Participants in the ASD group (n=52) were a…
