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.

Experience sampling of positive affect in adolescents with autism: Feasibility and preliminary findings / Megan KOVAC in Research in Autism Spectrum Disorders, 29-30 (September–October 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 29-30 (September–October 2016) . - p.57-65 Titre : Experience sampling of positive affect in adolescents with autism: Feasibility and preliminary findings Type de document : Texte imprimé et/ou numérique Auteurs : Megan KOVAC, Auteur ; Maya MOSNER, Auteur ; Stephanie MILLER, Auteur ; Eleanor K. HANNA, Auteur ; Gabriel S. DICHTER, Auteur Article en page(s) : p.57-65 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Experience sampling  Positive affect  Restricted interests Index. décimale : PER Périodiques Résumé : AbstractBackground Experience sampling is a powerful method for obtaining ecologically valid data from research participants in real-world contexts. Given the urgent need for innovative and sensitive outcome measures in autism spectrum disorder (ASD) research, the present study sought to examine the feasibility of using experience sampling of positive affect and behavior in adolescents with ASD. Method Nineteen high functioning adolescents with ASD and 20 sex and age matched controls completed smartphone- and Qualtrics® ?based experience sampling of positive affect and behavior six times over four days. Results Adherence was excellent: adolescents with ASD completed 85% of the assessments, compared to 93% in controls, and response rates were not impacted by age or IQ. Groups did not differ in positive affect overall or as a function of activities, nor did groups differ in the proportion of assessments completed during social or nonsocial activities. However, groups did differ in the proportion of assessments completed during preferred activities. Conclusions Results suggest that smartphone- and Qualtrics® ?based experience sampling with high functioning adolescents with ASD is feasible and captures real-world behaviors that would not be possible using laboratory-based measures.

Late Positive Potential ERP Responses to Social and Nonsocial Stimuli in Youth with Autism Spectrum Disorder / Stephen D. BENNING in Journal of Autism and Developmental Disorders, 46-9 (September 2016)

DICHTER, Auteur Article en page(s) : p.3068-3077 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Social  Restricted interests  Late positive potential  Motivation Index. décimale : PER Périodiques Résumé : We examined the late positive potential (LPP) event related potential in response to social and nonsocial stimuli from youths 9 to 19 years old with (n = 35) and without (n = 34) ASD. Social stimuli were faces with positive expressions and nonsocial stimuli were related to common restricted interests in ASD (e.g., electronics, vehicles, etc.). The ASD group demonstrated relatively smaller LPP amplitude to social stimuli and relatively larger LPP amplitude to nonsocial stimuli. There were no group differences in subjective ratings of images, and there were no significant correlations between LPP amplitude and ASD symptom severity within the ASD group. LPP results suggest blunted motivational responses to social stimuli and heightened motivational responses to nonsocial stimuli in youth with ASD.
