This study investigated the moderating role of context in ASD by comparing 32 individuals with ASD to 40 HCs during a social and a non-social provocation task. Compared to HCs, individuals with ASD showed similar externalizing behavior in the social context. In the non-social context reactions after provocation were enhanced relative to non-provoking situations. The findings implicate that the context is an important influencing variable when comparing individuals with ASD to HCs after being provoked. Impulsivity, trait aggression and empathy did not predict behavior in the ASD group but were partly related to observed behavior in HCs.

Evidence for Gender-Specific Endophenotypes in High-Functioning Autism Spectrum Disorder During Empathy / Karla SCHNEIDER in Autism Research, 6-6 (December 2013)  

Public ISBD [article]  inAutism Research > 6-6 (December 2013) . - p.506-521 Titre : Evidence for Gender-Specific Endophenotypes in High-Functioning Autism Spectrum Disorder During Empathy Type de document : Texte imprimé et/ou numérique Auteurs : Karla SCHNEIDER, Auteur ; Christina REGENBOGEN, Auteur ; Katharina D. PAULY, Auteur ; Anna GOSSEN, Auteur ; Daniel A. SCHNEIDER, Auteur ; Lea MEVISSEN, Auteur ; Tanja M. MICHEL, Auteur ; Ruben C. GUR, Auteur ; Ute HABEL, Auteur ; Frank SCHNEIDER, Auteur Année de publication : 2013 Article en page(s) : p.506-521 Langues : Anglais (eng) Mots-clés : autism  empathy  gender differences  fMRI  social interactions Index. décimale : PER Périodiques Résumé : Despite remarkable behavioral gender differences in patients with autism spectrum disorder (ASD), and growing evidence for a diminished male?:?female ratio for the putative “male disorder” ASD, aspects of gender are not addressed accordingly in ASD research. Our study aims at filling this gap by exploring empathy abilities in a group of 28 patients with high-functioning ASD and 28 gender-, age- and education-matched non-autistic subjects, for the first time by means of functional neuroimaging (fMRI). In an event-related fMRI paradigm, emotional (“E”) and neutral (“N”) video clips presented actors telling self-related short stories. After each clip, participants were asked to indicate their own emotion and its intensity as well as the emotion and intensity perceived for the actor. Behaviorally, we found significantly less empathic responses in the overall ASD group compared with non-autistic subjects, and inadequate emotion recognition for the neutral clips in the female ASD group compared with healthy women. Neurally, increased activation of the bilateral medial frontal gyrus was found in male patients compared with female patients, a pattern which was not present in the non-autistic group. Additionally, autistic women exhibited decreased activation of midbrain and limbic regions compared with non-autistic women, whereas there was no significant difference within the male group. While we did not find a fundamental empathic deficit in autistic patients, our data propose different ways of processing empathy in autistic men and women, suggesting stronger impairments in cognitive aspects of empathy/theory of mind for men, and alterations of social reciprocity for women.

Reduced Responsiveness to Social Provocation in Autism Spectrum Disorder / Isabella SCHNEIDER in Autism Research, 8-3 (June 2015)  

Public ISBD [article]  inAutism Research > 8-3 (June 2015) . - p.297-306 Titre : Reduced Responsiveness to Social Provocation in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Isabella SCHNEIDER, Auteur ; Christina REGENBOGEN, Auteur ; Nils KOHN, Auteur ; Florian D. ZEPF, Auteur ; Sarah BUBENZER-BUSCH, Auteur ; Frank SCHNEIDER, Auteur ; Ruben C. GUR, Auteur ; Ute HABEL, Auteur Article en page(s) : p.297-306 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  aggression  electrodermal activity  provocation Index. décimale : PER Périodiques Résumé : Deficits in emotion processing and social interaction are prominent symptoms of autism spectrum disorder (ASD). ASD has also been associated with aggressive tendencies towards self and others. The prevalence of aggressive behavior in this disorder, its etiology and its impact on social life are still unclear. This study investigated behavioral and physiological effects of social provocation in patients with ASD and healthy controls. We used a modified Taylor Aggression Paradigm in 24 high-functioning patients with ASD and 24 healthy controls. Participants were instructed to play against a fictitious human opponent. Money withdrawals toward the participant represented provocation and money deduction by the participant denoted aggressive behavior. Throughout the measurement, electrodermal activity (EDA) was recorded. Healthy controls showed higher aggressive responses to high provocation compared to low provocation, which demonstrated the effectiveness of the used procedure in eliciting aggression. Patients' responses were not influenced by the level of social provocation, although in both groups aggression was higher after lost compared to won trials. Physiologically, controls showed fewer but higher EDA amplitudes when responding aggressively, whereas patients displayed the opposite pattern of more but lower EDA amplitudes. The modified Taylor Aggression Paradigm successfully elicited aggression and revealed different behavioral and neurophysiological responses in patients and healthy controls. Patients' aggressive behavior as well as their physiological responses were less modulated by level of provocation compared to controls. Therapeutic attempts for patients might concentrate on improving empathic abilities and the understanding of social situations, including provocation and aggressive behavior.
