MOLESWORTH, Auteur ; Sylvie BERTHOZ, Auteur ; Francesca HAPPE, Auteur Année de publication : 2012 Article en page(s) : p.1504-1509 Langues : Anglais (eng) Mots-clés : Anhedonia  Social motivation  Autism spectrum disorders  Social anhedonia  Social interest Index. décimale : PER Périodiques Résumé : Diminished social motivation is one of the most striking features in autism. Yet, few studies have directly assessed the value people with an ASD place on social interactions, or how rewarding they report it to be. In the present study, we directly measure social motivation by looking at responses to a questionnaire assessing self-reported pleasure in social and non social situations. Twenty-nine adolescents with ASD and matched controls took part in the study. Our results reveal that children with an ASD differ from the controls with respect to social enjoyment, but not with respect to physical and other sources of hedonism. Further analyses demonstrate that the degree of social anhedonia correlates with autism severity.

From acoustics to grammar: Perceiving and interpreting grammatical prosody in adolescents with Asperger Syndrome / Coralie CHEVALLIER in Research in Autism Spectrum Disorders, 3-2 (April-june 2009)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 3-2 (April-june 2009) . - p.502-516 Titre : From acoustics to grammar: Perceiving and interpreting grammatical prosody in adolescents with Asperger Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Coralie CHEVALLIER, Auteur ; Francesca HAPPE, Auteur ; Ira NOVECK, Auteur ; Deirdre WILSON, Auteur Année de publication : 2009 Article en page(s) : p.502-516 Langues : Anglais (eng) Mots-clés : Asperger-Syndrome Prosody Grammar Language Index. décimale : PER Périodiques Résumé : We report findings concerning the understanding of prosody in Asperger Syndrome (AS), a topic which has attracted little attention and led to contradictory results. Ability to understand grammatical prosody was tested in three novel experiments. Experiment 1 assessed the interpretation of word stress, Experiment 2 focused on grammatical pauses, and Experiment 3 tested the discrimination of the question contour. Acoustic tasks were also used to assess the perception of pitch, duration, intensity and prosodic contours. AS participants performed as well as typically developing controls in all our tasks. This provides support in favour of the view that grammatical prosody is spared in Asperger Syndrome.

Measuring social attention and motivation in autism spectrum disorder using eye-tracking: Stimulus type matters / Coralie CHEVALLIER in Autism Research, 8-5 (October 2015)  

Public ISBD [article]  inAutism Research > 8-5 (October 2015) . - p.620-628 Titre : Measuring social attention and motivation in autism spectrum disorder using eye-tracking: Stimulus type matters Type de document : Texte imprimé et/ou numérique Auteurs : Coralie CHEVALLIER, Auteur ; Julia PARISH-MORRIS, Auteur ; Alana MCVEY, Auteur ; Keiran M. RUMP, Auteur ; Noah J. SASSON, Auteur ; John D. HERRINGTON, Auteur ; Robert T. SCHULTZ, Auteur Article en page(s) : p.620-628 Langues : Anglais (eng) Mots-clés : social attention  autism spectrum disorder  eye-tracking  social motivation  methodology  face processing Index. décimale : PER Périodiques Résumé : Autism Spectrum Disorder (ASD) is characterized by social impairments that have been related to deficits in social attention, including diminished gaze to faces. Eye-tracking studies are commonly used to examine social attention and social motivation in ASD, but they vary in sensitivity. In this study, we hypothesized that the ecological nature of the social stimuli would affect participants' social attention, with gaze behavior during more naturalistic scenes being most predictive of ASD vs. typical development. Eighty-one children with and without ASD participated in three eye-tracking tasks that differed in the ecological relevance of the social stimuli. In the “Static Visual Exploration” task, static images of objects and people were presented; in the “Dynamic Visual Exploration” task, video clips of individual faces and objects were presented side-by-side; in the “Interactive Visual Exploration” task, video clips of children playing with objects in a naturalistic context were presented. Our analyses uncovered a three-way interaction between Task, Social vs. Object Stimuli, and Diagnosis. This interaction was driven by group differences on one task only—the Interactive task. Bayesian analyses confirmed that the other two tasks were insensitive to group membership. In addition, receiver operating characteristic analyses demonstrated that, unlike the other two tasks, the Interactive task had significant classification power. The ecological relevance of social stimuli is an important factor to consider for eye-tracking studies aiming to measure social attention and motivation in ASD.

Salient Social Cues are Prioritized in Autism Spectrum Disorders Despite Overall Decrease in Social Attention / Coralie CHEVALLIER in Journal of Autism and Developmental Disorders, 43-7 (July 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-7 (July 2013) . - p.1642-1651 Titre : Salient Social Cues are Prioritized in Autism Spectrum Disorders Despite Overall Decrease in Social Attention Type de document : Texte imprimé et/ou numérique Auteurs : Coralie CHEVALLIER, Auteur ; Pascal HUGUET, Auteur ; Francesca HAPPE, Auteur ; Nathalie GEORGE, Auteur ; Laurence CONTY, Auteur Année de publication : 2013 Article en page(s) : p.1642-1651 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Stroop effect  Social attention  Social motivation  Eye contact Index. décimale : PER Périodiques Résumé : Diminished social attention is often considered to be a central deficit in autism spectrum disorders (ASDs). We further investigate this hypothesis by measuring the distracting power of social and non-social stimuli in the context of a Stroop task among children with ASD and typically developing controls (TDCs). Our results show that Stroop interference increases with social versus non-social distracters in TDCs, whereas the opposite pattern occurs in ASD. Within social stimuli, however, the superiority of direct gaze previously reported in the literature did not differ between the groups. Our data thus suggest that ASD children assign less weight to social than non-social stimuli, but that within social signals, salient stimuli remain prioritized.
