Marie Antoinette Hodge; Rebecca Sutherland; Kelsie A. Boulton; Sarah Jane Baracz; Natalie Ong; Beverley Bennett; Adam J. Guastella; Natalie Silove – Autism: The International Journal of Research and Practice, 2025
Studies have shown that there are differences between the presentations of males and females diagnosed with autism. There remains a developing understanding about how the presentation of autism differs between boys (hereafter referred to as 'assigned males at birth') and girls (assigned females at birth). This study sought to investigate the…

This study investigated sex and age differences in autistic behaviours in children with neurofibromatosis type 1 (NF1) who scored within the clinical range on the Social Responsiveness Scale - Second Edition (T score [greater than or equal to] 60). Thirty-four males and 28 females (3-16 years) were assessed with the Autism Diagnostic Observation…

Girls, more than boys, experience a decrease in the severity of autism symptoms during childhood. It is unclear, however, which specific autistic behaviors change more for girls than for boys. Trajectories of autism symptoms were evaluated using the Autism Diagnostic Observation Schedule-calibrated severity scores (ADOS-CSS). Change in the…

Kumar, Chandan Jyoti; Das, Priti Rekha – International Journal of Developmental Disabilities, 2022
Autism Spectrum Disorder (ASD) is a highly heterogeneous set of neurodevelopmental disorders with the global prevalence estimates of 2.20%, according to DSM5 criteria. With the advancements of technology and availability of huge amount of data, assistive tools for diagnosis of ASD are being developed using machine learning techniques. The present…

Wang, Li; Ong, Jia Hoong; Ponsot, Emmanuel; Hou, Qingqi; Jiang, Cunmei; Liu, Fang – Autism: The International Journal of Research and Practice, 2023
As an information-bearing auditory attribute of sound, pitch plays a crucial role in the perception of speech and music. Studies examining pitch processing in autism spectrum disorder have produced equivocal results. To understand this discrepancy from a mechanistic perspective, we used a novel data-driven method, the reverse-correlation paradigm,…

Rosen, Nicole E.; McCauley, James B.; Lord, Catherine – Autism: The International Journal of Research and Practice, 2022
Siblings play an important role in shaping the developmental trajectories of individuals with autism spectrum disorder. Having siblings has been associated with better social communication, non-verbal communication, and theory of mind abilities in autism spectrum disorder. However, little is known about the impact of siblings on adaptive skill…

Nina Masjedi; Elaine B. Clarke; Catherine Lord – Journal of Autism and Developmental Disorders, 2025
This study examined trajectories of repetitive sensorimotor (RSM), insistence on sameness (IS), and verbal RRBs from ages 2-19 in a well-characterized longitudinal cohort. We also tested the factor structure of the ADI-R restricted and repetitive behavior (RRB) domain at age 19 and the inclusion of a verbal RRBs factor, in addition to previously…

Motor abnormalities are highly prevalent in children with autism spectrum disorder and are strongly predictive of adaptive functioning. Despite the documented sex bias in the prevalence of the disorder, the impact of sex differences on motor abnormalities has been overlooked. The goal of this study was to investigate differences in the motor…

Roni Poyas Naharan; Yael Estrugo; Shahar Bar Yehuda; Nirit Bauminger-Zviely – Autism: The International Journal of Research and Practice, 2025
When partners coordinate their movement in time and space to reach a goal, they perform joint action, an important part of every interaction. Joint action involves motor abilities and socio-cognitive skills like theory of mind. Autistic children's lower joint motor coordination (joint action) abilities as well as their motor functioning and theory…

Xin Zhang; Xue-Ke Song; Wing-Chee So – Journal of Speech, Language, and Hearing Research, 2024
Purpose: Gesture delay in autistic infants and toddlers has been widely reported. The developmental trajectory of gesture production during early childhood is understudied. Thus, little is known about the possible changes of gesture production over time. The present study aimed to document the development of gesture production in autistic children…

Adaptive functioning, or the suite of skills essential for real-world, day-to-day functioning, includes daily living, communication, and socialization abilities. Even in the absence of co-occurring intellectual disability (IQ < 70), difficulties in adaptive functioning are prominent in autism spectrum disorder (ASD). Further, ASD individuals…

Rodriguez, Geovanna; Drastal, Kim; Hartley, Sigan L. – Autism: The International Journal of Research and Practice, 2021
Youth with autism spectrum conditions have been shown to be at an increased risk for bullying victimization. The overall aim of this study was to identify factors associated with increased risk for bullying victimization in youth with autism during middle childhood to early adolescence (aged 5-12 years) and to explore the potential time-ordered…

Guthrie, Whitney; Wetherby, Amy M.; Woods, Juliann; Schatschneider, Christopher; Holland, Renee D.; Morgan, Lindee; Lord, Catherine E. – Autism: The International Journal of Research and Practice, 2023
Robust evidence supports the efficacy of early autism intervention. Despite broad consensus that earlier intervention leads to better outcomes, evidence for this has been limited to correlational studies. This study examined timing effects of the Early Social Interaction (ESI) model, a parent-implemented intervention, using a complete crossover…
