Titre : Intention Perception in High Functioning People with Autism Spectrum Disorders Using Animacy Displays Derived from Human Actions Type de document : Texte imprimé et/ou numérique Auteurs : Phil MCALEER, Auteur ; Jim W. KAY, Auteur ; Frank E. POLLICK, Auteur ; Melissa D. RUTHERFORD, Auteur Année de publication : 2011 Article en page(s) : p.1053-1063 Langues : Anglais (eng) Mots-clés : Autism Intention Perception Animacy Index. décimale : PER Périodiques Résumé : The perception of intent in Autism Spectrum Disorders (ASD) often relies on synthetic animacy displays. This study tests intention perception in ASD via animacy stimuli derived from human motion. Using a forced choice task, 28 participants (14 ASDs; 14 age and verbal-I.Q. matched controls) categorized displays of Chasing, Fighting, Flirting, Following, Guarding and Playing, from two viewpoints (side, overhead) in both animacy and full video displays. Detailed analysis revealed no differences between populations in accuracy, or response patterns. Collapsing across groups revealed Following and Video displays to be most accurately perceived. The stimuli and intentions used are compared to those of previous studies, and the implication of our results on the understanding of Theory of Mind in ASD is discussed.

Titre : Young children with autism spectrum disorders imitate in the context of others’ prior intention Type de document : Texte imprimé et/ou numérique Auteurs : Chi-Tai HUANG, Auteur ; Chung-Hsin CHIANG, Auteur ; Chao-Yi HUNG, Auteur Article en page(s) : p.83-91 Langues : Anglais (eng) Mots-clés : autism spectrum disorder imitation intention prior intention Index. décimale : PER Périodiques Résumé : Many studies have shown that children with autism spectrum disorder have some understanding of intentions behind others’ goal-directed actions on objects. It is not clear whether they understand intentions at a high level of abstraction reliant on the context in which the actions occur. This study tested their understanding of others’ prior intentions with typically developing and developmentally delayed children. We replicated Carpenter et al.’s test of the ability to understand prior intentions embedded in the social situation with an additional context of no prior intention. Results showed that when the experimenter’s intention was made known before the demonstration, children without autism spectrum disorder performed not only better than the autism spectrum disorder children but also better than themselves when there was no information about prior intention. No between-condition difference was found in the autism spectrum disorder group. It thus appears that children with autism spectrum disorder have difficulty decoupling intentions from the context of the situation. The present findings, together with previous evidence for the intactness of the ability to understand and to imitate goal-directed actions, suggest that asymmetrical imitation performance occurs at different levels of understanding of intention by children with autism spectrum disorder.

Titre : Attribution of intentions in autism spectrum disorder: A study of event-related potentials Type de document : Texte imprimé et/ou numérique Auteurs : João Miguel FERNANDES, Auteur ; Sara SOARES, Auteur ; Ricardo LOPES, Auteur ; Rita JERÓNIMO, Auteur ; J. Bernardo BARAHONA-CORREA, Auteur Article en page(s) : p.847-860 Langues : Anglais (eng) Mots-clés : Adult Autism Spectrum Disorder Autistic Disorder Evoked Potentials/physiology Female Humans Intention Male Social Perception attribution of intentions autism spectrum disorders event related potentials social cognition & theory of mind Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is characterized by social cognition deficits, including difficulties inferring the intentions of others. Although deficits in attribution of intentions (AI) have been consistently replicated in ASD, their exact nature remains unexplored. Here we registered the electrophysiological correlates of a nonverbal social cognition task to investigate AI in autistic adults. Twenty-one male autistic adults and 30 male neurotypical volunteers performed a comic strips task depicting either intentional action (AI) or physical causality with or without human characters, while their electroencephalographic signal was recorded. Compared to neurotypical volunteers, autistic participants were significantly less accurate in correctly identifying congruence in the AI condition, but not in the physical causality conditions. In the AI condition a bilateral posterior positive event-related potential (ERP) occurred 200-400?ms post-stimulus (the ERP intention effect) in both groups. This waveform comprised a P200 and a P300 component, with the P200 component being larger for the AI condition in neurotypical volunteers but not in autistic individuals, who also showed a longer latency for this waveform. Group differences in amplitude of the ERP intention effect only became evident when we compared autistic participants to a subgroup of similarly performing neurotypical participants, suggesting that the atypical ERP waveform in ASD is an effect of group, rather than a marker of low-task performance. Together, these results suggest that the lower accuracy of the ASD group in the AI task may result from impaired early attentional processing and contextual integration of socially relevant cues. LAY SUMMARY: To understand why autistic people have difficulties in inferring others' intentions, we asked participants to judge the congruence of the endings of comic strips depicting either intentional actions (e.g., fetching a chair to reach for something) or situations solely following physical rules (e.g., an apple falling on someone's head), while their electrical brain activity was recorded. Autistic individuals had more difficulties in inferring intentions than neurotypical controls, which may reflect impaired attention and contextual integration of social cues.

WEISS, Auteur Article en page(s) : p.415-427 Langues : Anglais (eng) Mots-clés : ADHD autism children clinicians intention mental health psychotherapy theory of planned behaviour Index. décimale : PER Périodiques Résumé : Autistic children and adolescents are more likely than non-autistic youth to experience mental health problems, such as anxiety or depression, but less likely to receive psychotherapy to address these concerns. Recent research indicates that clinician factors, such as knowledge, attitudes, confidence and beliefs, can impact their decisions to provide care, though this work has primarily focused on adults or within the context of one kind of treatment (cognitive behaviour therapy). The current study examined psychological predictors (e.g. attitudes and confidence) of clinicians’ intention to deliver psychotherapy to autistic youth and those with attention-deficit hyperactivity disorder. Participants included 611 clinicians across publicly funded agencies in Ontario, Canada. Multiple mediation analyses revealed that clinician knowledge on mental health-related topics (e.g. core symptoms, developing treatment plans and identifying progress towards treatment goals) was associated with intention to treat autistic clients or clients with attention-deficit hyperactivity disorder, and normative pressures and attitudes partially mediated this association. Clinicians felt less likely to treat autistic clients than clients with attention-deficit hyperactivity disorder, partly because of differences in attitudes, normative pressures and knowledge. This research suggests that targeted training around autism and mental health care may be a useful initiative for agency staff.

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.
