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.

Do Children with Autism have a Theory of Mind? A Non-verbal Test of Autism vs. Specific Language Impairment / Livia COLLE in Journal of Autism and Developmental Disorders, 37-4 (April 2007)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 37-4 (April 2007) . - p.716-723 Titre : Do Children with Autism have a Theory of Mind? A Non-verbal Test of Autism vs. Specific Language Impairment Type de document : Texte imprimé et/ou numérique Auteurs : Livia COLLE, Auteur ; Simon BARON-COHEN, Auteur ; Jacqueline HILL, Auteur Année de publication : 2007 Article en page(s) : p.716-723 Langues : Anglais (eng) Mots-clés : Theory-of-mind Non-verbal-false-belief Autism Language-impairments Index. décimale : PER Périodiques Résumé : Children with autism have delays in the development of theory of mind. However, the sub-group of children with autism who have little or no language have gone untested since false belief tests (FB) typically involve language. FB understanding has been reported to be intact in children with specific language impairment (SLI). This raises the possibility that a non-verbal FB test would distinguish children with autism vs. children with SLI. The present study tested two predictions: (1) FB understanding is to some extent independent of language ability; and (2) Children with autism with low language levels show specific impairment in theory of mind. Results confirmed both predictions. Results are discussed in terms of the role of language in the development of mindreading.

Narrative Discourse in Adults with High-Functioning Autism or Asperger Syndrome / Livia COLLE in Journal of Autism and Developmental Disorders, 38-1 (January 2008)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 38-1 (January 2008) . - p.28-40 Titre : Narrative Discourse in Adults with High-Functioning Autism or Asperger Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Livia COLLE, Auteur ; Simon BARON-COHEN, Auteur ; Sally WHEELWRIGHT, Auteur ; Heather K. J. VAN DER LELY, Auteur Année de publication : 2008 Article en page(s) : p.28-40 Langues : Anglais (eng) Mots-clés : Narrative-abilities Adults-with-HFA/AS Temporal-expressions Anaphoric-pronouns Theory-of-mind Index. décimale : PER Périodiques Résumé : We report a study comparing the narrative abilities of 12 adults with high-functioning autism (HFA) or Asperger Syndrome (AS) versus 12 matched controls. The study focuses on the use of referential expressions (temporal expressions and anaphoric pronouns) during a story-telling task. The aim was to assess pragmatics skills in people with HFA/AS in whom linguistic impairments are more subtle than in classic autism. We predicted no significant differences in general narrative abilities between the two groups, but specific pragmatic deficits in people with AS. We predicted they use fewer personal pronouns, temporal expressions and referential expressions, which require theory of mind abilities. Results confirmed both predictions. These findings provide initial evidence of how social impairments can produce mild linguistic impairments.
