How Anxious Do You Think I Am? Relationship Between State and Trait Anxiety in Children With and Without ASD During Social Tasks / J. MERTENS in Journal of Autism and Developmental Disorders, 47-12 (December 2017)

GROSSMAN, Auteur Année de publication : 2017 Article en page(s) : p.3692-3703 Langues : Anglais (eng) Mots-clés : Asd  Anxiety  Biophysiology  Standardized measures Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) often exhibit increased anxiety, even in non-stressful situations. We investigate general anxiousness (anxiety trait) and responses to stressful situations (anxiety state) in 22 adolescents with ASD and 32 typically developing controls. We measured trait anxiety with standardized self- and parent-reported questionnaires. We used a Biopac system to capture state anxiety via skin conductance responses, mean heart rate and heart rate variability during high- and low-anxiety tasks. Results reveal higher trait anxiety in adolescents with ASD (p < 0.05) and no group difference in state anxiety. Increased parent-reported trait anxiety may predict decreased state anxiety during high-stress conditions. Together, these findings suggest that higher trait anxiety may result in dampened physical responses to stress.

Motion-Capture Patterns of Voluntarily Mimicked Dynamic Facial Expressions in Children and Adolescents With and Without ASD / E. ZANE in Journal of Autism and Developmental Disorders, 49-3 (March 2019)

GROSSMAN, Auteur Article en page(s) : p.1062-1079 Langues : Anglais (eng) Mots-clés : Asd  Emotional facial expressions  Motion capture  Social communication Index. décimale : PER Périodiques Résumé : Research shows that neurotypical individuals struggle to interpret the emotional facial expressions of people with Autism Spectrum Disorder (ASD). The current study uses motion-capture to objectively quantify differences between the movement patterns of emotional facial expressions of individuals with and without ASD. Participants volitionally mimicked emotional expressions while wearing facial markers. Recorded marker movement was grouped by expression valence and intensity. We used Growth Curve Analysis to test whether movement patterns were predictable by expression type and participant group. Results show significant interactions between expression type and group, and little effect of emotion valence on ASD expressions. Together, results support perceptions that expressions of individuals with ASD are different from-and more ambiguous than-those of neurotypical individuals'.

Perceptions of self and other: Social judgments and gaze patterns to videos of adolescents with and without autism spectrum disorder / R. B. GROSSMAN in Autism, 23-4 (May 2019)  

Public ISBD [article]  inAutism > 23-4 (May 2019) . - p.846-857 Titre : Perceptions of self and other: Social judgments and gaze patterns to videos of adolescents with and without autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : R. B. GROSSMAN, Auteur ; J. MERTENS, Auteur ; E. ZANE, Auteur Article en page(s) : p.846-857 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  communication and language  social cognition and social behavior Index. décimale : PER Périodiques Résumé : Neurotypical adults often form negative first impressions of individuals with autism spectrum disorder and are less interested in engaging with them socially. In contrast, individuals with autism spectrum disorder actively seek out the company of others who share their diagnosis. It is not clear, however, whether individuals with autism spectrum disorder form more positive first impressions of autistic peers when diagnosis is not explicitly shared. We asked adolescents with and without autism spectrum disorder to watch brief video clips of adolescents with and without autism spectrum disorder and answer questions about their impressions of the individuals in the videos. Questions were related to participants' perceptions of the social skills of the individuals in the video, as well as their own willingness to interact with that person. We also measured gaze patterns to the faces, eyes, and mouths of adolescents in the video stimuli. Both participant groups spent less time gazing at videos of autistic adolescents. Regardless of diagnostic group, all participants provided more negative judgments of autistic than neurotypical adolescents in the videos. These data indicate that, without being explicitly informed of a shared diagnosis, adolescents with autism spectrum disorder form negative first impressions of autistic adolescents that are similar to, or lower than, those formed by neurotypical peers.
