This study tests a handwriting model for children and youth with Autism Spectrum Disorder (ASD) that displays the relationships between handwriting process and product characteristics, and the predictors of these characteristics. Structural Equation Modelling was used to test the model for children and youth with ASD (n = 50) and typically…

Purpose: One of the core features that can be experienced by adults on the autism spectrum is hyper- and hyporeactivity to sensory stimuli. Research suggests that executive functioning (EF) impairments are related to sensory issues. In this study the relationship between sensory processing issues and EF was investigated. We expected sensory…

Physical exercise is widely reported beneficial to executive functions in children with autism spectrum disorder. However, its impact on self-regulation in the population remains unknown. This study is to test whether two types of physical exercise (cognitively engaging vs non-cognitively engaging) benefited self-regulation and whether the social,…

Atypical connectivity patterns have been observed for individuals with autism spectrum disorders (ASD), particularly across the triple-network model. The current study investigated brain-behavior relationships in the context of social skills and executive function profiles for ASD youth. We calculated connectivity measures from diffusion tensor…

Prefrontal synthesis (PFS) is a component of constructive imagination. It is defined as the process of mentally juxtaposing objects into novel combinations. For example, to comprehend the instruction "put the cat under the dog and above the monkey," it is necessary to use PFS in order to correctly determine the spatial arrangement of the…

Executive function is an area of challenge for both children with fetal alcohol spectrum disorders (FASD) and children with autism spectrum disorder (ASD). Parent ratings of everyday executive function relate to a range of outcomes, including social functioning in ASD. Comparisons between FASD and ASD have revealed both overlapping and distinct…

The critical role of executive functioning in autism as well as the co-occurring mental health challenges common among autistic youth support to the immense value of interventions targeting executive functioning for enhancing mental health services for autistic children. The goal of the present study was to conduct a randomized feasibility trial…

Compared to their neurotypically developing peers, children and adolescents with autism spectrum disorders tend to have attenuated neural responses in the parietal lobe when attending sensory input, as reflected by a reduced P3b amplitude measured with electroencephalography. However, it is unknown whether a reduced P3b amplitude in autistic…

Purpose: Relative clauses present a well-known processing asymmetry between object-extracted and subject-extracted dependencies across both typical and atypical populations. The present study aimed at exploring the comprehension of object and subject relative clauses as conceptualized by the Relativized Minimality framework in autistic children…

This meta-analysis aimed to systematically investigate the cognitive and linguistic correlates of both word decoding and reading comprehension among children with Autism Spectrum Disorder (ASD) across orthographies. Based on data from 26 studies of 1.92- to 18.92-year-old children with ASD, we found that (1) intelligence, theory of mind, and…

In this scoping review on 34 studies, we examined the use of immersive virtual reality (IVR) in neurodevelopmental disorders (NDD). IVR was mostly used in connection with autism spectrum disorder (ASD) for assessment of and intervention in social skills, and in attention deficit hyperactivity disorder (ADHD) for assessment of executive…

Adaptive functioning is central to autistic individuals' independence and well-being. However, autism spectrum disorder (ASD) is associated with poor adaptive functioning, even in the absence of cognitive delays or deficits. This study examined how age and executive function associate with adaptive functioning--particularly the gap between…

Sensory features, executive and attentional impairments are frequently reported in individuals with autism spectrum disorders (ASD). However, little is known about their complex relationships. In this study, we aim to examine the executive and attentional difficulties related to distinct sensory profiles. We identified sensory profiles with a…

Impairments in executive function (EF) among individuals with autism spectrum disorder and their association with negative academic, adaptive, and social functioning outcomes have been widely reported over the past 20 years. However, there remains a lack of understanding of EF in autism during the preschool period, an age at which several crucial…

There is a long tradition of research into autistic people's executive function skills. Yet, despite decades of research on EF in autism, the existing literature remains contradictory and 'confusing', with a large -- and unresolved -- discrepancy between small-to-moderate effect sizes demonstrated on laboratory-based EF tasks and large effect…
