Preserved Self-other Distinction During Empathy in Autism is Linked to Network Integrity of Right Supramarginal Gyrus / Ferdinand HOFFMANN in Journal of Autism and Developmental Disorders, 46-2 (February 2016)
[article]
Titre : Preserved Self-other Distinction During Empathy in Autism is Linked to Network Integrity of Right Supramarginal Gyrus Type de document : Texte imprimé et/ou numérique Auteurs : Ferdinand HOFFMANN, Auteur ; Svenja KOEHNE, Auteur ; Nikolaus STEINBEIS, Auteur ; Isabel DZIOBEK, Auteur ; Tania SINGER, Auteur Année de publication : 2016 Article en page(s) : p.637-648 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Self-other distinction Empathy Emotional egocentricity Resting-state functional connectivity Right supramarginal gyrus Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) shows deficits in self-other distinction during theory of mind (ToM). Here we investigated whether ASD patients also show difficulties in self-other distinction during empathy and if potential deficits are linked to dysfunctional resting-state connectivity patterns. In a first study, ASD patients and controls performed an emotional egocentricity paradigm and a ToM task. In the second study, resting-state connectivity of right temporo-parietal junction and right supramarginal gyrus (rSMG) were analysed using a large-scale fMRI data set. ASD patients exhibited deficient ToM but normal emotional egocentricity, which was paralleled by reduced connectivity of regions of the ToM network and unimpaired rSMG network connectivity. These results suggest spared self-other distinction during empathy and an intact rSMG network in ASD.

Titre : The effect of being imitated on empathy for pain in adults with high-functioning autism: Disturbed self-other distinction leads to altered empathic responding Type de document : Texte imprimé et/ou numérique Auteurs : L. DE COSTER, Auteur ; Jan R. WIERSEMA, Auteur ; Eliane DESCHRIJVER, Auteur ; Marcel BRASS, Auteur Article en page(s) : p.712-727 Langues : Anglais (eng) Mots-clés : autism spectrum disorders empathy for pain imitation psychophysiology self-other distinction social cognition and social behavior Index. décimale : PER Périodiques Résumé : Autism spectrum disorder is a neurodevelopmental disorder that is associated with problems in empathy. Recent research suggests that impaired control over self-other overlap based on motor representations in individuals with autism spectrum disorder might underlie these difficulties. In order to investigate the relationship of self-other distinction and empathy for pain in high-functioning autism and matched controls, we manipulated self-other distinction by using a paradigm in which participants are either imitated or not by a hand on a computer screen. A strong pain stimulus is then inflicted on the observed hand. Behavioral and physiological results in this study showed that overall affective responses while watching pain movies were the same in adults with high-functioning autism as in controls. Furthermore, controls showed higher affective responding after being imitated during the whole experiment, replicating previous studies. Adults with high-functioning autism, however, showed increased empathic responses over time after being imitated. Further exploratory analyses suggested that while affective responding was initially lower after being imitated compared to not being imitated, affective responding in the latter part of the experiment was higher after being imitated. These results shed new light on empathic abilities in high-functioning autism and on the role of control over self-other representational sharing.

Titre : Disentangling Neural Sources of the Motor Interference Effect in High Functioning Autism: An EEG-Study Type de document : Texte imprimé et/ou numérique Auteurs : Eliane DESCHRIJVER, Auteur ; Jan R. WIERSEMA, Auteur ; Marcel BRASS, Auteur Article en page(s) : p.690-700 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Imitation N190 P3 Readiness potential Self-other distinction Index. décimale : PER Périodiques Résumé : The role of imitation in autism spectrum disorder (ASD) is controversial. Researchers have argued that deficient control of self- and other-related motor representations (self-other distinction) might explain imitation difficulties. In a recent EEG study, we showed that control of imitation relies on high-level as well as on low-level cognitive processes. Here, we aimed to further our insights into control of imitation deficits in ASD. We focused on congruency effects in the P3 (high-level), the N190 and the readiness potential (RP; low-level). We predicted smaller congruency effects within the P3 in the ASD group. However, we found differences in the RP and not in the P3-component. Thus, high-level self-other distinction centred on motor actions may be preserved in ASD, while impairments are reflected during motor preparation.
