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…

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…

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…

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…

Objectives: The purpose of this article is to review research that has been conducted over the past five years on language development, reading skills and word learning with the use of the eye tracking machine as regards the population with autism spectrum disorder (ASD) in comparison to typically developed population. Materials and methods: A…

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…

Feasible and accurate assessment tools developed for non-specialists are needed to scale community-based models of autism evaluation. The purpose of this study was to evaluate use of the Screening Tool for Autism in Toddlers and Young Children (STAT) when used by primary care practitioners (n = 10) across a statewide system of early diagnosis set…

Tschida, Jessica E.; Yerys, Benjamin E. – Autism: The International Journal of Research and Practice, 2022
Executive function challenges are commonly reported in the home setting for children with an autism spectrum disorder diagnosis (hereafter, autism), but little is known about these challenges in the school setting. A total of 337 youth (autism, N = 241 and typically developing, N = 96) were assessed using Behavior Rating Inventory of Executive…

Deserno, Marie K.; Fuhrmann, Delia; Begeer, Sander; Borsboom, Denny; Geurts, Hilde M.; Kievit, Rogier A. – Autism: The International Journal of Research and Practice, 2023
Autism is often associated with early developmental delays in language and motor skills. However, little is known about the complex dynamic processes that drive the co-development of such early difficulties. The aim of the present study was to model the parallel growth of language and motor skills in a cohort of infants and to explore differences…

The last decades of neuroimaging research has revealed atypical development of intrinsic functional connectivity within and between large-scale cortical networks in autism spectrum disorder, but much remains unknown about cortico-subcortical developmental connectivity atypicalities. This study examined cortico-striatal developmental intrinsic…

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…

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…

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…

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,…
