Communicative intentions in autism spectrum disorder / Magdalena SCHÜTZ in Research in Autism Spectrum Disorders, 79 (November 2020)
[article]
Titre : Communicative intentions in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Magdalena SCHÜTZ, Auteur ; Angela CIARAMIDARO, Auteur ; Anne MARTINELLI, Auteur ; Ramona ÖLLER, Auteur ; Daniela HARTMANN, Auteur ; Grit HEIN, Auteur ; Vassil IOTZOV, Auteur ; Livia COLLE, Auteur ; Cristina BECCHIO, Auteur ; Henrik WALTER, Auteur ; Christine M. FREITAG, Auteur Article en page(s) : 101666 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder fMRI Intention Communication Social interaction Index. décimale : PER Périodiques Résumé : Background Deficits in social communication and interaction are among the core symptoms of Autism Spectrum Disorder (ASD). Intention understanding in particular has been shown to be impaired in ASD. However, only one previous study has explicitly assessed the understanding of communicative intentions in ASD. Thus, the aim of the present study was to compare neural activation during the observation of communicative and non-communicative actions in participants with ASD and typically developing (TD) controls using functional magnetic resonance imaging (fMRI). Based on recent findings that show that the degree of involvement of the observer has an impact on neural activation, the present study included first- and third-person perspective stimuli. Method Twenty-five male TD (mean age 20.41?±?3.39) and twenty-two male participants with ASD (mean age 18.60?±?3.55) were included. Stimuli consisted of videos in which actors performed an action with an everyday object. Actions were either private or communicative; communicative actions were either directed at the observer (first-person) or at a third person. Results The ASD group showed reduced activation in the human middle temporal complex (hMT+) across all conditions. However, modulation of activation in response to different conditions remained intact in ASD. Additionally, while TD showed an increase in premotor cortex (PMC) activation in response to communicative actions directed at them, the ASD group showed a decrease in activation. Conclusions These findings suggest an early processing deficit with regard to human biological motion in ASD. Furthermore, results reflect a reduced preparedness for social interactions in ASD compared to TD when addressed directly.

Titre : Intention Attribution in Children and Adolescents with Autism Spectrum Disorder: An EEG Study Type de document : Texte imprimé et/ou numérique Auteurs : Magdalena SCHÜTZ, Auteur ; Sara BOXHOORN, Auteur ; Andreas M. MÜHLHERR, Auteur ; Hannah MÖSSINGER, Auteur ; Christine M. FREITAG, Auteur ; Christina LUCKHARDT, Auteur Article en page(s) : p.1431-1443 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The ability to infer intentions from observed behavior and predict actions based on this inference, known as intention attribution (IA), has been hypothesized to be impaired in individuals with autism spectrum disorder (ASD). The underlying neural processes, however, have not been conclusively determined. The aim of this study was to examine the neural signature of IA in children and adolescents with ASD, and to elucidate potential links to contextual updating processes using electroencephalography. Results did not indicate that IA or early contextual updating was impaired in ASD. However, there was evidence of aberrant processing of expectation violations in ASD, particularly if the expectation was based on IA. Results are discussed within the context of impaired predictive coding in ASD.
