Reduced social coordination in Autism Spectrum Disorders / Tiziana ZALLA in Research in Autism Spectrum Disorders, 26 (June 2016)
[article]
Titre : Reduced social coordination in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique 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.

Titre : Saccadic eye movements in adults with high-functioning autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Tiziana ZALLA, Auteur ; Magali SEASSAU, Auteur ; Fabienne CAZALIS, Auteur ; Doriane GRAS, Auteur ; Marion LEBOYER, Auteur Année de publication : 2018 Article en page(s) : p.195-204 Langues : Anglais (eng) Mots-clés : brainstem,cerebellum,eye tracking,Gap/Overlap,saccade,sensorimotor Index. décimale : PER Périodiques Résumé : In this study, we examined the accuracy and dynamics of visually guided saccades in 20 adults with autism spectrum disorder, as compared to 20 typically developed adults using the Step/Overlap/Gap paradigms. Performances in participants with autistic spectrum disorder were characterized by preserved Gap/Overlap effect, but reduced gain and peak velocity, as well as a greater trial-to-trial variability in task performance, as compared to the control group. While visual orienting and attentional engagement were relatively preserved in individuals with autistic spectrum disorder, overall these findings provide evidence that abnormal oculomotor behavior in autistic spectrum disorder reflects an altered sensorimotor control due to cerebellar abnormalities, rather than a deficit in the volitional control of eye movements. This study contributes to a growing body of evidence implicating this structure in the physiopathology of autism.

Titre : Stimulus-reward association and reversal learning in individuals with Asperger Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Tiziana ZALLA, Auteur ; Marion LEBOYER, Auteur ; Anca-Maria SAV, Auteur Année de publication : 2009 Article en page(s) : p.913-923 Langues : Anglais (eng) Mots-clés : Inhibition Executive-functions Orbitofrontal-cortex Social-deficits Index. décimale : PER Périodiques Résumé : In the present study, performance of a group of adults with Asperger Syndrome (AS) on two series of object reversal and extinction was compared with that of a group of adults with typical development. Participants were requested to learn a stimulus-reward association rule and monitor changes in reward value of stimuli in order to gain as many points as possible. In order to assess whether difficulties with stimulus-reward association learning and with reversal and/or extinction might be related to social and behavioural impairments, we performed correlation analyses between test measures and scores measuring the severity of clinical symptoms in the areas of repetitive behaviours and social interaction as assessed by the Autism Diagnostic Interview-Revised (ADI-R) [Lord, C., Rutter, M., & Le Couteur, A. (1994). Autism diagnostic interview-revised: A recise version of a diagnostic interview for caregivers of individuals with possible pervasive developmental disorders. Journal of Autism and Developmental Disorders, 24, 659–685]. Individuals with AS showed difficulties in establishing rapid stimulus-reward associations, whereas no severe impairment was observed in reversal and extinction learning. In addition, the present findings show that these difficulties correlate with scores in social reciprocal interaction, suggesting that the diminished ability in the assignment of reinforcement value to incoming stimuli might be related to disturbances in social behaviour often reported in autism spectrum disorders.
