Visual Attention and Autistic Behavior in Infants with Fragile X Syndrome / Jane E. ROBERTS in Journal of Autism and Developmental Disorders, 42-6 (June 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-6 (June 2012) . - p.937-946 Titre : Visual Attention and Autistic Behavior in Infants with Fragile X Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Jane E. ROBERTS, Auteur ; Deborah D. HATTON, Auteur ; Anna C. LONG, Auteur ; Vittoria ANELLO, Auteur ; John COLOMBO, Auteur Année de publication : 2012 Article en page(s) : p.937-946 Langues : Anglais (eng) Mots-clés : Fragile X  Autism  Early detection  Heart rate  Visual attention  High-risk infants Index. décimale : PER Périodiques Résumé : Aberrant attention is a core feature of fragile X syndrome (FXS), however, little is known regarding the developmental trajectory and underlying physiological processes of attention deficits in FXS. Atypical visual attention is an early emerging and robust indictor of autism in idiopathic (non-FXS) autism. Using a biobehavioral approach with gaze direction and heart activity, we examined visual attention in infants with FXS at 9, 12, and 18 months of age with a cross-sectional comparison to 12-month-old typically developing infants. Analyses revealed lower HR variability, shallower HR decelerations, and prolonged look durations in 12-month old infants with FXS compared to typical controls. Look duration and increased latency to disengage attention were correlated with severity of autistic behavior but not mental age.

Brief Report: Cognitive Control of Social and Nonsocial Visual Attention in Autism / Antoinette SABATINO-DICRISCIO in Journal of Autism and Developmental Disorders, 46-8 (August 2016)

DICHTER, Auteur Article en page(s) : p.2797-2805 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Visual attention  Cognitive control  Eyetracking Index. décimale : PER Périodiques Résumé : Prosaccade and antisaccade errors in the context of social and nonsocial stimuli were investigated in youth with autism spectrum disorder (ASD; n = 19) a matched control sample (n = 19), and a small sample of youth with obsessive compulsive disorder (n = 9). Groups did not differ in error rates in the prosaccade condition for any stimulus category. In the antisaccade condition, the ASD group demonstrated more errors than the control group for nonsocial stimuli related to circumscribed interests, but not for other nonsocial stimuli or for social stimuli. Additionally, antisaccade error rates were predictive of core ASD symptom severity. Results indicate that the cognitive control of visual attention in ASD is impaired specifically in the context of nonsocial stimuli related to circumscribed interests.

Fostering Spontaneous Visual Attention in Children on the Autism Spectrum: A Proof?of?Concept Study Comparing Singing and Speech / Anne THOMPSON GRACE in Autism Research, 11-5 (May 2018)  

Public ISBD [article]  inAutism Research > 11-5 (May 2018) . - p.732-737 Titre : Fostering Spontaneous Visual Attention in Children on the Autism Spectrum: A Proof?of?Concept Study Comparing Singing and Speech Type de document : Texte imprimé et/ou numérique Auteurs : Anne THOMPSON GRACE, Auteur ; Allen ABEL LARRY, Auteur Article en page(s) : p.732-737 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  social cognition and social behavior  music therapy  visual attention  school?age children Index. décimale : PER Périodiques Résumé : Children on the autism spectrum are reported to have lower rates of social gaze as early as toddlerhood, and this pattern persists across the lifespan. Finding ways to promote more natural and spontaneous engagement in social interactions may help to boost developmental opportunities in the child's home and community settings. This proof?of?concept study hypothesized that a video of a singer would elicit more attention to the performer, particularly to her face, than a video of her reading a story, and that the child's familiarity with the material would enhance attention. Sixteen children on the autism spectrum (7?10 years old) watched 4 videos 1 min long comprising a favorite song or story, and an unfamiliar song and story. Eye movements were recorded, and three?way repeated measures ANOVAs examined the proportion of total valid visual dwell time and fixations, in each trial and each target area. For proportion of both dwell time and fixation counts, children were significantly more likely to look at the performer's face and body and less at the prop during singing than story?telling and when familiar rather than unfamiliar material was presented. These findings raise important issues for supporting children to naturally initiate looking toward a person's face. Autism Res 2018, 11: 732?737. ? 2018 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary Children on the autism spectrum may have difficulty looking at people, particularly their faces. In this study, children watched videos of someone singing or reading a story. The results show that children look more at the person if they were singing and if the story was familiar to them. Using songs and familiar stories may be a way to help children with autism to naturally engage with others.

Patterns of Visual Attention to Faces and Objects in Autism Spectrum Disorder / James C. MCPARTLAND in Journal of Autism and Developmental Disorders, 41-2 (February 2011)

Point of gaze was recorded during passive viewing of images of human faces, inverted human faces, monkey faces, three-dimensional curvilinear objects, and two-dimensional geometric patterns. Individuals with ASD obtained lower scores on measures of face recognition and social-emotional functioning but exhibited similar patterns of visual attention. In individuals with ASD, face recognition performance was associated with social adaptive function. Results highlight heterogeneity in manifestation of social deficits in ASD and suggest that naturalistic assessments are important for quantifying atypicalities in visual attention.

Reduced engagement of visual attention in children with autism spectrum disorder / C. S. MCLAUGHLIN in Autism, 25-7 (October 2021)

It is unclear, however, whether these are specifically social differences; it is possible that they are a result of broader alterations in engaging and disengaging visual attention. We used eye-tracking technology with children with autism spectrum disorder (n = 35) and typical development (n = 32), showing them both social and nonsocial imaging to test their visual attention. Children with autism spectrum disorder had a significant difference in how long it took them to look from an image in the middle to one on the side, depending on whether the middle image stayed on the screen or flashed off before the one on the side appeared. This difference was present for both social and nonsocial images, and was related to cognitive ability for only the children with autism spectrum disorder. Our findings suggest that children with autism spectrum disorder have differences in general processes of engaging visual attention that are not specifically social in nature, and that these processes may relate to cognitive ability in autism spectrum disorder. Affected processes of visual engagement in autism spectrum disorder may contribute to symptoms like reduced eye contact, but social-specific symptoms of autism spectrum disorder likely do not stem from reduced visual engagement alone.
