Disembedding performance and eye gaze behavior of adolescents with Autism Spectrum Disorder / Melissa H. BLACK in Research in Autism Spectrum Disorders, 66 (October 2019)

Gaze behavior has provided some insights in to mechanisms underlying this purported superiority in children, however evidence is limited and requires additional investigation. Method The performance and gaze behavior of 27 adolescents with ASD and 27 matched typically developing (TD) peers were examined during the Figure Ground Subtest of the Test of Visual Perception Skills-third edition (TVPS-3). Results Compared to their TD counterparts, adolescents with ASD were no different in accuracy, however, had a longer response time. Differences in gaze behavior were also observed, characterized by adolescents with ASD spending less time viewing the incorrect and target figures, and spending a greater proportion of time viewing irrelevant areas of the stimuli compared to TD adolescents. Conclusions Results suggest that while altered visual perception was observed, this did not contribute to superiority in disembedding tasks in adolescents with ASD. Future research is required to elucidate conditions under which altered visual perception may contribute to behavioral superiority.

Effect of Visual Information on Postural Control in Children with Autism Spectrum Disorder / Yi Huey LIM in Journal of Autism and Developmental Disorders, 50-9 (September 2020)

Visual processing in children with autism spectrum disorder (ASD) was hypothesized to be less efficient and thus they would display a less stable standing posture than typically developing children. The present study compared the static standing responses and attentional demands of 15 children with ASD and 18 control participants in conditions of eyes open and eyes closed. The results showed that postural responses and attention invested in standing were similar between the participant groups in the two visual conditions. Both groups displayed a more stable posture when their eyes were open in comparison to eyes closed. The finding suggests that normal postural control development could occur in children with ASD.

Motivation to participate in structured physical activity for autistic youth: A systematic scoping review / Michelle L. WONG in Autism, 28-10 (October 2024)  

Public ISBD [article]  inAutism > 28-10 (October 2024) . - p.2430-2444 Titre : Motivation to participate in structured physical activity for autistic youth: A systematic scoping review Type de document : texte imprimé Auteurs : Michelle L.

A scoping review was conducted to explore motivational factors influencing participation in structured physical activity for autistic youth. Relevant databases were searched using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses with the inclusion of stakeholder consultation, to synthesise existing literature describing the participation and motivations of autistic youth in structured physical activities. Eighteen publications met the eligibility criteria. Qualitative data were extracted and analysed using directed content analysis and then mapped to the motivational constructs of the self-determination theory. Autism-specific themes falling outside of the self-determination theory were coded inductively. Competence was the most reported psychological need (k = 14), with intrinsic motivation being the most common motivational regulator (k = 12). Inductive analysis revealed one additional theme, which was the impact of the sensory environment on autistic youths' motivation to participate. Findings indicate that meeting the psychological needs of autistic youth support self-determined motivation to participate in structured physical activities, although fulfilling these needs may differ from their neurotypical peers. Additional autism-specific factors may also influence motivation to participate in structured physical activities. Future research should examine motivational factors that support engagement in structured physical activities through the lens of autistic youth and their experiences. Lay abstract Autistic youth participate less in physical education classes and organised sport than their neurotypical peers. We conducted a review of existing studies to investigate what is known about what motivates (and does not motivate) autistic youth to take part in structured physical activities. We systematically searched electronic databases and found 18 publications that met the criteria to be included in this review. Data from these studies were extracted and mapped to the self-determination theory to identify factors that support (or undermine) motivation for autistic youth. We also discussed the findings with autistic individuals and other relevant stakeholders to discover how the review related to their experiences. Our results found competence (youth feeling competent in their athletic and social skills and abilities) to be the most reported psychological need impacting motivation for autistic youth. Intrinsic motivation (participating for enjoyment and satisfaction) was the most common facilitator of motivation. Autism-specific themes outside of the self-determination theory were mapped inductively, and we found that the sensory environment was a prominent theme reported to influence the motivation of autistic youth not covered by the self-determination theory. The findings of this review suggest that supporting the psychological needs of autistic youth can foster motivation to engage in physical activity, although how these needs are met can differ from their neurotypical peers. Future research should examine motivational factors that support engagement in structured physical activities through the lens of autistic youth and their experiences.

Postural and Cortical Responses Following Visual Occlusion in Adults With and Without ASD / Kwang Leng GOH in Journal of Autism and Developmental Disorders, 48-5 (May 2018)

Evidence from electroencephalography suggests individual perturbation evoked response (PER) components represent specific aspects of postural disturbance processing; P1 reflects the detection and N1 reflects the evaluation of postural instability. Despite the importance of these cortical responses to postural control, PERs to a perturbation in adults with autism spectrum disorder (ASD) have yet to be reported. The aim was to compare PERs to visual perturbation under varied postural stability conditions in adults with and without ASD. This study is the first to report that while the assessment of postural set is intact, adults with ASD use more cortical resources to integrate and interpret visual perturbations for postural control.

Standing Postural Control in Individuals with Autism Spectrum Disorder: Systematic Review and Meta-analysis / Yi Huey LIM in Journal of Autism and Developmental Disorders, 47-7 (July 2017)

This review compared the effect of different sensory conditions on static standing postural control between ASD and neurotypical individuals. Results from 19 studies indicated a large difference in postural control between groups across all sensory conditions. This review revealed sensorimotor and multiple sensory processing deficits in ASD. The tendency for individuals with ASD to be more susceptible to postural instability with use of visual information compared with somatosensory information suggests perinatal alterations in sensory development. There is further scope for studies on the use of sensory information and postural control to provide additional evidence about sensorimotor processing in ASD.
