Dissociation between executed and imagined bimanual movements in autism spectrum conditions / Alessandro PIEDIMONTE in Autism Research, 11-2 (February 2018)
[article]
Titre : Dissociation between executed and imagined bimanual movements in autism spectrum conditions Type de document : Texte imprimé et/ou numérique Auteurs : Alessandro PIEDIMONTE, Auteur ; Massimiliano CONSON, Auteur ; Alessandro FROLLI, Auteur ; Stefania BARI, Auteur ; Francesco Della GATTA, Auteur ; Marco RABUFFETTI, Auteur ; Roberto KELLER, Auteur ; Anna BERTI, Auteur ; Francesca GARBARINI, Auteur Année de publication : 2018 Article en page(s) : p.376-384 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Autism spectrum conditions (ASC) are characterized by social?communicative deficits and repetitive stereotyped behaviors. Altered motor coordination is also observed and a dysfunction of motor imagery has been recently reported on implicit tasks. However, no information on explicit motor imagery abilities is available in ASC. Here, we employed a spatial bimanual task to concurrently assess motor coordination and explicit motor imagery in autism. A secondary objective of the study was to evaluate these abilities across two populations of ASC, namely adolescents and adults with ASC. To this aim, we took advantage of the circles?lines task in which where participants were asked to continuously draw: right hand lines (unimanual condition); right hand lines and left hand circles (bimanual condition); right hand lines while imagining to draw left hand circles (imagery condition). For each participant, an Ovalization Index (OI) was calculated as a deviation of the right hand drawing trajectory from an absolute vertical axis. Results showed a significant and similar coupling effect in the bimanual condition (i.e., a significant increase of the OI values with respect to the unimanual condition) in both controls and ASC participants. On the contrary, in the imagery condition, a significant coupling effect was found only in controls. Furthermore, adult controls showed a significantly higher imagery coupling effect in comparison to all the other groups. These results demonstrate that atypical motor imagery processes in ASC are not limited to implicit tasks and suggest that development of neural structures involved in motor imagery are immature in ASC. Autism Res 2018, 11: 376–384. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary Autism spectrum conditions (ASC) are characterized by social?communicative and motor coordination difficulties but in many cases also by an impaired capability to imagine movements. In this study we found that while two handed coordination in ASC can be developed as well as in typically developed persons, the development of motor imagery could still be immature in ASC, leading to difficulties in imagining, understanding as well as programming and coordinating complex movements.

Titre : Monochannel Preference in Autism Spectrum Conditions Revealed by a Non-Visual Variant of Rubber Hand Illusion Type de document : Texte imprimé et/ou numérique Auteurs : Mattia GALIGANI, Auteur ; Carlotta FOSSATARO, Auteur ; Patrizia GINDRI, Auteur ; Massimiliano CONSON, Auteur ; Francesca GARBARINI, Auteur Article en page(s) : p.4252-4260 Langues : Anglais (eng) Mots-clés : Autism spectrum conditions Multisensory integration Rubber hand illusion Touch bOdy ownership Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum conditions (ASC) are less susceptible to multisensory delusions, such as rubber hand illusion (RHI). Here, we investigate whether a monochannel variant of RHI is more effective in inducing an illusory feeling of ownership in ASC. To this aim, we exploit a non-visual variant of the RHI that, excluding vision, leverages only on the somatosensory channel. While the visual-tactile RHI does not alter the perceived hand position in ASC individuals, the tacto-tactile RHI effectively modulates proprioception to a similar extent as that found in typical development individuals. These findings suggest a more effective integration of multiple inputs originating from the same sensory channel in ASC, revealing a monochannel preference in this population.
