Intact Automatic Imitation and Typical Spatial Compatibility in Autism Spectrum Disorder: Challenging the Broken Mirror Theory / Sophie SOWDEN in Autism Research, 9-2 (February 2016)
[article]
Titre : Intact Automatic Imitation and Typical Spatial Compatibility in Autism Spectrum Disorder: Challenging the Broken Mirror Theory Type de document : Texte imprimé et/ou numérique Auteurs : Sophie SOWDEN, Auteur ; Svenja KOEHNE, Auteur ; Caroline CATMUR, Auteur ; Isabel DZIOBEK, Auteur ; Geoffrey BIRD, Auteur Article en page(s) : p.292-300 Langues : Anglais (eng) Mots-clés : autism imitation mirror neurons broken mirror theory individual differences Index. décimale : PER Périodiques Résumé : A lack of imitative behavior is frequently described as a core feature of Autism Spectrum Disorder (ASD), and is consistent with claims of mirror neuron system dysfunction in these individuals. Previous research has questioned this characterization of ASD however, arguing that when tests of automatic imitation are used—which do not require higher-level cognitive processing—imitative behavior is intact or even enhanced in individuals with ASD. In Experiment 1, 60 adult individuals with ASD and a matched Control group completed an automatic imitation task in which they were required to perform an index or a middle finger lift while observing a hand making either the same, or the alternate, finger movement. Both groups demonstrated a significant imitation effect whereby actions were executed faster when preceded by observation of the same action, than when preceded by the alternate action. The magnitude of this “imitation effect” was statistically indistinguishable in the ASD and Control groups. Experiment 2 utilized an improved automatic imitation paradigm to demonstrate that, when automatic imitation effects are isolated from those due to spatial compatibility, increasing autism symptom severity is associated with an increased tendency to imitate. Notably, there was no association between autism symptom severity and spatial compatibility, demonstrating the specificity of the link between ASD symptoms and increased imitation. These results provide evidence against claims of a lack of imitative behavior in ASD, and challenge the “Broken Mirror Theory of Autism.” En ligne : http://dx.doi.org/10.1002/aur.1511 Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=282

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.
