Purpose: Increased local-to-global interference has been found in those with ASD, AD and OCD, and as such, may represent a transdiagnostic marker. As a first step to investigating this, we aimed to assess the overlap in traits of these disorders in a non-clinical sample, and whether local-global processing relates to the traits of the three…

Michael A. Levine; Huan Chen; Ericka L. Wodka; Brian S. Caffo; Joshua B. Ewen – Journal of Autism and Developmental Disorders, 2025
Background: The Wechsler Intelligence Scale for Children (WISC) employs a hierarchical model of general intelligence in which index scores separate out different clinically-relevant aspects of intelligence; the test is designed such that index scores are statistically independent from one another within the normative sample. Whether or not the…

Purpose: With the current study, we aimed to reveal the similarities and differences in sensory profiles between Williams syndrome (WS) and autism spectrum disorder. Methods: Using the sensory profile questionnaire completed by the caregivers, we analyzed the WS (n = 60, 3.4-19.8 years) and autistic (n = 39, 4.2-14.0 years) groups. Results: The…

We describe the development of 236 children with Angelman syndrome (AS) using the Bayley Scales of Infant and Toddler Development, Third Edition. Multilevel linear mixed modeling approaches were used to explore differences between molecular subtypes and over time. Individuals with AS continue to make slow gains in development through at least age…

Tsirgiotis, Joanna M.; Young, Robyn L.; Weber, Nathan – Journal of Autism and Developmental Disorders, 2022
Growing evidence suggests that autistic females are more likely to be diagnostically overlooked than males, perhaps due to differences in ASD presentations (van Wijngaarden-Cremers in JAMA 44:627-635, 2014). To investigate specific behaviours in which differences lie, we analysed profiles of 777 children using the Childhood Autism Rating Scale…

Joshua Anbar; Maurice Metoyer; Christopher J. Smith; Nicole L. Matthews – Journal of Autism and Developmental Disorders, 2025
Purpose: Most assessment tools used to diagnose and characterize autism spectrum disorder (ASD) were developed for in-person administration. The coronavirus disease 2019 (COVID-19) pandemic resulted in the need to adapt traditional assessment tools for online administration with only minimal evidence to support validity of such practices. Methods:…

Powell, Bradley; Van Herwegen, Jo – Journal of Autism and Developmental Disorders, 2022
This study examined individual differences as well as the development of sensory processing difficulties in children with Williams syndrome (WS) using a cross-sectional (Experiment 1) and longitudinal design (Experiment 2). In Experiment 1, a clustering approach of sensory processing scores suggested two groups. Experiment 2 showed that the…

In two studies, we used the Gottschaldt's Hidden Figure Test (GHFT) for assessing figure disembedding ability in children aged 7-11. Study 1 demonstrated in a large sample of typically developing children that GHFT accuracy and time scores differed across age groups, without sex and socioeconomic differences. Thus, we provided normative data only…

This study was a systematic review of research using the Wechsler Intelligence Scale for Children (WISC) with Autism Spectrum Disorder (ASD) to examine cognitive characteristics of children with ASD beyond the impact of revisions based on WISC and diagnostic criteria changes. The classic "islets of ability" was found in individuals with…

Sensory features are part of the diagnostic criteria for autism and include sensory hypo/hyper reactivity and unusual sensory interest; however, additional sensory differences, namely differences in sensory integration, have not been routinely explored. This study characterized sensory integration differences in a cohort of children (n = 93) with…

Wu, Chin-Chin; Chu, Ching-Lin; Stewart, Lydia; Chiang, Chung-Hsin; Hou, Yuh-Ming; Liu, Jiun-Horng – Journal of Autism and Developmental Disorders, 2020
The present longitudinal study examined the utility of the screening tool for autism in 2-year-olds (STAT) in detecting autism spectrum disorder (ASD) in toddlers who are less than 24 months of age. The study sample, which consisted of 119 toddlers with developmental problems, were assessed when they were between 16 and 24 months of age (Time 1)…

Sulforaphane has been reported to possibly improve core symptoms associated with autism spectrum disorders from mostly small size studies. Here we present results of a larger randomized clinical trial (N = 108) in China. There were no significant changes in caregiver rated scales between sulforaphane and placebo groups. However, clinician rated…

Daniel Berends; Catherine A. Bent; Giacomo Vivanti; Cheryl Dissanayake; Kristelle Hudry – Journal of Autism and Developmental Disorders, 2024
Purpose: While research indicates that both the core features of autism and associated developmental skills influence adaptive behaviour outcomes, results to date suggest greater influence of the latter than the former, and little attention has been given to how the interaction of both together might impact functional disability. Seeking to expand…

Amin D. Lotfizadeh; Brendan Gard; Cynthia Rico; Alan Poling; Kristen R. Choi – Journal of Autism and Developmental Disorders, 2025
Behavior analysts frequently use the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) to assess the language and social skills of children with autism in everyday practice and in research. Despite the widespread use of the VB-MAPP, its psychometric characteristics have not been extensively investigated. To provide information…

Lauren Gardner; Callie Gilchrest; Jonathan M. Campbell – Journal of Autism and Developmental Disorders, 2024
The diagnostic criteria for autism spectrum disorder in the DSM-5-TR features the option to designate levels of support for social communication (SC) and restricted, repetitive behaviors (RRB). These levels are conceptual in nature, but research indicates standardized assessment outcomes correspond with clinician-assigned levels of support. The…
