Don't touch me! autistic traits modulate early and late ERP components during visual perception of social touch / Leehe PELED-AVRON in Autism Research, 10-6 (June 2017)  

Public ISBD [article]  inAutism Research > 10-6 (June 2017) . - p.1141-1154 Titre : Don't touch me! autistic traits modulate early and late ERP components during visual perception of social touch Type de document : Texte imprimé et/ou numérique Auteurs : Leehe PELED-AVRON, Auteur ; Simone G. SHAMAY-TSOORY, Auteur Article en page(s) : p.1141-1154 Langues : Anglais (eng) Mots-clés : autistic traits  interpersonal touch  ERP  LPP  P1 Index. décimale : PER Périodiques Résumé : Although individuals with autism spectrum disorder (ASD) have impaired responses to interpersonal touch, the underlying neural correlates remain largely unknown. Here, we examined the neural correlates that underlie interpersonal touch perception in individuals with either high or low autistic traits. Fifty-three participants were classified as having either high or low autistic traits based on their performance on the autism quotient (AQ) questionnaire. We hypothesized that individuals with high AQ scores would have relatively high touch hypervigilance, reflected as earlier P1 and stronger late positive potential (LPP) responses, two components of event-related potentials that serve as electrophysiological markers of anxiety bias. We recorded each participant's electroencephalography activity during presentation of images depicting human touch, object touch, and non-touch control images. Consistent with our hypothesis, AQ scores were positively correlated with social touch aversion. Moreover, participants with high AQ scores had earlier P1 and stronger LPP responses when presented with human touch compared to the control images. Importantly, a regression model revealed that earlier P1 and larger LPP amplitude measured during social touch observation can accurately predict higher autistic trait levels. Taken together, these findings indicate that individuals with high levels of autistic traits may have a hypervigilant response to observed social touch.

Empathic Embarrassment Accuracy in Autism Spectrum Disorder / Noga ADLER in Autism Research, 8-3 (June 2015)  

Public ISBD [article]  inAutism Research > 8-3 (June 2015) . - p.241-249 Titre : Empathic Embarrassment Accuracy in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Noga ADLER, Auteur ; Jonathan DVASH, Auteur ; Simone G. SHAMAY-TSOORY, Auteur Article en page(s) : p.241-249 Langues : Anglais (eng) Mots-clés : empathic embarrassment  empathic embarrassment accuracy  empathy  autism spectrum disorder Index. décimale : PER Périodiques Résumé : Empathic accuracy refers to the ability of perceivers to accurately share the emotions of protagonists. Using a novel task assessing embarrassment, the current study sought to compare levels of empathic embarrassment accuracy among individuals with autism spectrum disorders (ASD) with those of matched controls. To assess empathic embarrassment accuracy, we compared the level of embarrassment experienced by protagonists to the embarrassment felt by participants while watching the protagonists. The results show that while the embarrassment ratings of participants and protagonists were highly matched among controls, individuals with ASD failed to exhibit this matching effect. Furthermore, individuals with ASD rated their embarrassment higher than controls when viewing themselves and protagonists on film, but not while performing the task itself. These findings suggest that individuals with ASD tend to have higher ratings of empathic embarrassment, perhaps due to difficulties in emotion regulation that may account for their impaired empathic accuracy and aberrant social behavior.

Recognition of ‘Fortune of Others’ Emotions in Asperger Syndrome and High Functioning Autism / Simone G. SHAMAY-TSOORY in Journal of Autism and Developmental Disorders, 38-8 (September 2008)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 38-8 (September 2008) . - p.1451-1461 Titre : Recognition of ‘Fortune of Others’ Emotions in Asperger Syndrome and High Functioning Autism Type de document : Texte imprimé et/ou numérique Auteurs : Simone G. SHAMAY-TSOORY, Auteur Année de publication : 2008 Article en page(s) : p.1451-1461 Langues : Anglais (eng) Mots-clés : Asperger-syndrome Fortune-of-others-emotions Envy Schadenfreude Index. décimale : PER Périodiques Résumé : ‘Fortune of others’ emotions, such as envy and gloating over the other’s misfortune, are complex emotions experienced in situations where events are presumed to be desirable or undesirable for another person. The present paper explores the notion that individuals with AS and HFA are impaired in understanding of envy and gloating. We tested the ability of adults with AS/HFA to understand envy and gloating and compared their performance to that of age-matched healthy controls. The ‘fortune of others’ emotion task and an additional theory-of-mind (ToM) task were based on a task designed to assess ToM on the basis of eye gaze direction. Individuals with AS and HFA showed no difficulty on basic ToM conditions, but were impaired in their ability to identify envy and gloating. Furthermore, the ability to recognize these emotions was related to scores on a self-rating scale of perspective-taking ability and the ToM task.
