Altered bodily self-consciousness and peripersonal space in autism / C. L. MUL in Autism, 23-8 (November 2019)
[article]
Titre : Altered bodily self-consciousness and peripersonal space in autism Type de document : Texte imprimé et/ou numérique Auteurs : C. L. MUL, Auteur ; F. CARDINI, Auteur ; Steven D. STAGG, Auteur ; S. SADEGHI ESFAHLANI, Auteur ; D. KIOURTSOGLOU, Auteur ; P. CARDELLICCHIO, Auteur ; J. E. ASPELL, Auteur Article en page(s) : p.2055-2067 Langues : Anglais (eng) Mots-clés : autism spectrum disorders bodily self-consciousness full body illusion multisensory integration peripersonal space Index. décimale : PER Périodiques Résumé : There is some evidence that disordered self-processing in autism spectrum disorders is linked to the social impairments characteristic of the condition. To investigate whether bodily self-consciousness is altered in autism spectrum disorders as a result of multisensory processing differences, we tested responses to the full body illusion and measured peripersonal space in 22 adults with autism spectrum disorders and 29 neurotypical adults. In the full body illusion set-up, participants wore a head-mounted display showing a view of their 'virtual body' being stroked synchronously or asynchronously with respect to felt stroking on their back. After stroking, we measured the drift in perceived self-location and self-identification with the virtual body. To assess the peripersonal space boundary we employed an audiotactile reaction time task. The results showed that participants with autism spectrum disorders are markedly less susceptible to the full body illusion, not demonstrating the illusory self-identification and self-location drift. Strength of self-identification was negatively correlated with severity of autistic traits and contributed positively to empathy scores. The results also demonstrated a significantly smaller peripersonal space, with a sharper (steeper) boundary, in autism spectrum disorders participants. These results suggest that bodily self-consciousness is altered in participants with autism spectrum disorders due to differences in multisensory integration, and this may be linked to deficits in social functioning.

Titre : When social and action spaces diverge: A study in children with typical development and autism Type de document : Texte imprimé et/ou numérique Auteurs : Michela CANDINI, Auteur ; V. GIUBERTI, Auteur ; E. SANTELLI, Auteur ; G. DI PELLEGRINO, Auteur ; F. FRASSINETTI, Auteur Article en page(s) : p.1687-1698 Langues : Anglais (eng) Mots-clés : autism spectrum disorders cooperation interpersonal space peripersonal space tool-use Index. décimale : PER Périodiques Résumé : The space around the body has been defined as action space (peripersonal space) and a social space (interpersonal space). Within the current debate about the characteristics of these spaces, here we investigated the functional properties and plasticity of action and social space in developmental age. To these aims, children with typical development and autism spectrum disorders were submitted to Reaching- and Comfort-distance tasks, to assess peripersonal and interpersonal space, respectively. Participants approached a person (confederate) or an object and stopped when they thought they could reach the stimulus (Reaching-distance task), or they felt comfortable with stimulus' proximity (Comfort-distance task). Both tasks were performed before and after a cooperative tool-use training, in which participant and confederate actively cooperated to reach tokens by using either a long (Experiment 1) or a short (Experiment 2) tool. Results showed that in both groups, peripersonal space extended following long-tool-use but not short-tool-use training. Conversely, in typical development, but not in autism spectrum disorders children, interpersonal space toward confederate reduced following the cooperative tool-use training. These findings reveal that action and social spaces are functionally dissociable both in typical and atypical development, and that action but not social space regulation is intact in children with autism.
