Self-referenced processing, neurodevelopment and joint attention in autism / Peter C. MUNDY in Autism, 14-5 (September 2010)  

Public ISBD [article]  inAutism > 14-5 (September 2010) . - p.408-429 Titre : Self-referenced processing, neurodevelopment and joint attention in autism Type de document : Texte imprimé et/ou numérique Auteurs : Peter C. MUNDY, Auteur ; Heather A. HENDERSON, Auteur ; Mary GWALTNEY, Auteur Année de publication : 2010 Article en page(s) : p.408-429 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This article describes a parallel and distributed processing model (PDPM) of joint attention, self-referenced processing and autism. According to this model, autism involves early impairments in the capacity for rapid, integrated processing of self-referenced (proprioceptive and interoceptive) and other-referenced (exteroceptive) information. Measures of joint attention have proven useful in research on autism because they are sensitive to the early development of the ‘parallel’ and integrated processing of self- and other-referenced stimuli. Moreover, joint attention behaviors are a consequence, but also an organizer of the functional development of a distal distributed cortical system involving anterior networks including the prefrontal and insula cortices, as well as posterior neural networks including the temporal and parietal cortices. Measures of joint attention provide early behavioral indicators of atypical development in this parallel and distributed processing system in autism. In addition it is proposed that an early, chronic disturbance in the capacity for integrating self- and other-referenced information may have cascading effects on the development of self awareness in autism. The assumptions, empirical support and future research implications of this model are discussed.

Social Attention in a Virtual Public Speaking Task in Higher Functioning Children With Autism / William JARROLD in Autism Research, 6-5 (October 2013)  

Public ISBD [article]  inAutism Research > 6-5 (October 2013) . - p.393-410 Titre : Social Attention in a Virtual Public Speaking Task in Higher Functioning Children With Autism Type de document : Texte imprimé et/ou numérique Auteurs : William JARROLD, Auteur ; Peter C. MUNDY, Auteur ; Mary GWALTNEY, Auteur ; Jeremy BAILENSON, Auteur ; Naomi HATT, Auteur ; Nancy MCINTYRE, Auteur ; Kwanguk KIM, Auteur ; Marjorie SOLOMON, Auteur ; Stephanie NOVOTNY, Auteur ; Lindsay SWAIN, Auteur Article en page(s) : p.393-410 Langues : Anglais (eng) Mots-clés : cognition and learning  school-aged development  social attention  individual differences Index. décimale : PER Périodiques Résumé : Impairments in social attention play a major role in autism, but little is known about their role in development after preschool. In this study, a public speaking task was used to study social attention, its moderators, and its association with classroom learning in elementary and secondary students with higher functioning autism spectrum disorder (HFASD). Thirty-seven students with HFASD and 54 age- and intelligence quotient (IQ)-matched peers without symptoms of ASD were assessed in a virtual classroom public speaking paradigm. This paradigm assessed the ability to attend to nine avatar peers seated at a table, while simultaneously answering self-referenced questions. Students with HFASD looked less frequently to avatar peers in the classroom while talking. However, social attention was moderated in the HFASD sample such that students with lower IQ, and/or more symptoms of social anxiety, and/or more attention deficit/hyperactivity disorder inattentive symptoms, displayed more atypical social attention. Group differences were more pronounced when the classroom contained social avatars versus nonsocial targets. Moreover, measures of social attention rather than nonsocial attention were significantly associated with parent report and objective measures of learning in the classroom. The data in this study support the hypothesis of the Social Attention Model of ASD that social attention disturbance remains part of the school-aged phenotype of autism that is related to syndrome-specific problems in social learning. More research of this kind would likely contribute to advances in the understanding of the development of the spectrum of autism and educational intervention approaches for affected school-aged children.

A Virtual Joy-Stick Study of Emotional Responses and Social Motivation in Children with Autism Spectrum Disorder / Kwanguk KIM in Journal of Autism and Developmental Disorders, 45-12 (December 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-12 (December 2015) . - p.3891-3899 Titre : A Virtual Joy-Stick Study of Emotional Responses and Social Motivation in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Kwanguk KIM, Auteur ; M.

MUNDY, Auteur Année de publication : 2015 Article en page(s) : p.3891-3899 Langues : Anglais (eng) Mots-clés : Motivation sociale  Interpersonal distance  Emotional accuracy  Social-motivation  Reward sensitivity  Virtual avatar  High function Autism Spectrum Disorder Index. décimale : PER Périodiques Résumé : A new virtual reality task was employed which uses preference for interpersonal distance to social stimuli to examine social motivation and emotion perception in children with Autism Spectrum Disorders. Nineteen high function children with higher functioning Autism Spectrum Disorder (HFASD) and 23 age, gender, and IQ matched children with typical development (TD) used a joy stick to position themselves closer or further from virtual avatars while attempting to identify six emotions expressed by the avatars, happiness, fear, anger, disgust, sadness, and surprise that were expressed at different levels of intensity. The results indicated that children with HFASD displayed significantly less approach behavior to the positive happy expression than did children with TD, who displayed increases in approach behavior to higher intensities of happy expressions. Alternatively, all groups tended to withdraw from negative emotions to the same extent and there were no diagnostic group differences in accuracy of recognition of any of the six emotions. This pattern of results is consistent with theory that suggests that some children with HFASD display atypical social-approach motivation, or sensitivity to the positive reward value of positive social–emotional events. Conversely, there was little evidence that a tendency to withdraw from social–emotional stimuli, or a failure to process social emotional stimuli, was a component of social behavior task performance in this sample of children with HFASD.
