A renewed interest in intrapersonal cognition has recently emerged suggesting a putative dissociation between impaired declarative processes, such as autobiographical memory, and spared implicit processes, such as the sense of agency (SoA) in ASDs. However, so far only a few studies have investigated the integrity of SoA using tasks exclusively tapping reflective mechanisms. Since pre-reflective processes of SoA are based on the same predictive internal models that are involved in planning and monitoring actions, we hypothesized that pre-reflective aspects of SoA, as measured by the intentional binding effect, would be altered in adults with high functioning autism spectrum disorders, relative to volunteers with typical development. Here, in accordance with our hypothesis, we report reduced IB in participants with ASDs.

Reduced social coordination in Autism Spectrum Disorders / Tiziana ZALLA in Research in Autism Spectrum Disorders, 26 (June 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 26 (June 2016) . - p.71-79 Titre : Reduced social coordination in Autism Spectrum Disorders Type de document : texte imprimé Auteurs : Tiziana ZALLA, Auteur ; Marco SPERDUTI, Auteur ; Giovanna GIRARDI, Auteur ; Chiara CHELINI, Auteur ; Marion LEBOYER, Auteur ; Sacha BOURGEOIS-GIRONDE, Auteur Article en page(s) : p.71-79 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorders  Coordination  Theory of Mind  Self-reference  Decision making Index. décimale : PER Périodiques Résumé : In the present study, we investigated whether individuals with Autism Spectrum Disorders (ASD) were able to coordinate with an unknown partner on the same outcome using a two-person pure coordination game. Twenty-one adults with ASD and twenty-one typically developed (TD) control participants were presented with sets of four items, and were asked to choose one of these items under three conditions: picking one’s own personal preferred item, guessing what might be the partner’s preference, and choosing an item in order to coordinate with the partner’s choice. Each set included a salient item that stood out for its distinctive properties, known as the focal point. The results showed that individuals with ASD choose more often their preferred items than the salient cues to coordinate with others and to guess the partner's preference, as compared to TD controls. Performance for coordination was related to clinical scores assessing difficulties in communication and the severity of the autistic traits, but was unrelated to verbal intelligence and verbally mediated Theory-of-Mind task. These findings suggest that self-bias processes in decision-making might be a source of impairment in social coordination and interaction in ASD.
