Purpose: An internal model deficit is considered to underlie developmental coordination disorder (DCD); thus, children with DCD have an altered sense of agency (SoA), which is associated with depressive symptoms. Furthermore, the perception of action-outcome regularity is present in early development, is involved in the generation of SoA, and has…

This study aimed to describe the behavioral profile of individuals with SYNGAP1-ID. Parents/carers of 30 individuals aged 3-18 years old with a diagnosis of SYNGAP1-ID and 21 typically developing individuals completed the Vineland-3 Adaptive Behavior Scale and the Child Behavior Checklist. We found that those with SYNGAP1-ID showed fewer adaptive…

Purpose: The Arabic verb system features a nonlinear root and pattern derivational morphology. Previous studies suggest that young Arabic and Hebrew speakers' early verb use is based on semantic complexity rather than derivational morphological structure. The present study examines the role of morphological and semantic complexity in the emergence…

Text comprehension can be facilitated in many ways, including enabling the listener to see pictures illustrating the story, to read along silently, or to read along aloud. The purpose of this study was to determine whether any of these three supports facilitated text comprehension in adults with intellectual and/or developmental disability (IDD).…

Background: Employment is often central to individuals' lives. However, individuals with intellectual or developmental disabilities are often absent from the workplace, and little research has examined their interest in working. Aims: This study examined whether people with intellectual and/or developmental disabilities want jobs; why they do or…

Background: Having an intellectual disability increases the likelihood for exhibiting impairments in vision, hearing, and balance. The intersection of these issues has yet to be described in a large cohort. Methods: By hosting the largest public health database for individuals with intellectual disability, Special Olympics (SO) offers…

Purpose: The purpose of this study was to conduct a scoping review of literature focused on the effects of developmental language disorder (DLD) on writing skills across the life span to highlight gaps in our knowledge of how to support writing for this population. Method: We adopted the five-step framework for conducting scoping reviews outlined…

This report provides updated prevalence estimates for diagnosed autism spectrum disorder, intellectual disability, and other developmental delay among children 3-17 years from the 2019-2021 National Health Interview Survey, with differences in prevalence examined between years and by sex, age group, and race and Hispanic origin. Estimates are also…

Background: Language interventions are complex behavioural interventions, making it difficult to distinguish the specific factors contributing to efficacy. The efficacy of oral language comprehension interventions varies greatly, but the reasons for this have received little attention. Aims: The aim of this meta-analysis was to examine which…

Background: The home literacy environment (HLE) has rarely been examined for individuals with neurodevelopmental disorders, including individuals with Williams syndrome and Down syndrome. Method: The current study surveyed carers of individuals with Down syndrome (n = 48) and Williams syndrome (n = 18) in the United Kingdom (UK). Results: The…

Introduction: Mental health concerns have been noted to be highly prevalent for youth with intellectual disability (ID), with or without autism spectrum disorder (ASD). The purpose of the current study was to examine a Canadian sample of youth with ID, with or without ASD, to explore caregiver-reported percentages, predictors, and treatment…

This study investigates typing skill acquisition in Japanese children with developmental dyslexia (DD) and other developmental disorders (ADHD, ASD). Given that phonological processing difficulties impair reading and writing, typing may serve as an alternative skill for written expression. Sixty-one students (ages 7-18) participated in five typing…

This cross-sectional study explored stressful situations of caregivers related to life events of their children suffering from neurodevelopmental disorders along with potential contributing factors. A total of 906 caregivers of children with diagnosed neurodevelopmental disorder, from eight administrative districts and two city corporation areas…

To date, little is known about sensory processing in Williams syndrome (WS) and the similarities of the sensory profile in individuals with WS compared to people with other neurodevelopmental disorders. The current review aims to consolidate available evidence on sensory processing in WS. Eighteen primary studies investigating sensory processing…

Background: Future planning has emerged as a global issue for families of individuals with intellectual and developmental disabilities due to the longer lives and limited long-term services and supports in the adult disability system. While it has received greater attention, most future planning studies only included parents of individuals with…
