Autistic traits affect interpersonal motor coordination by modulating strategic use of role-based behavior / A. CURIONI in Molecular Autism, 8 (2017)
[article]
Titre : Autistic traits affect interpersonal motor coordination by modulating strategic use of role-based behavior Type de document : Texte imprimé et/ou numérique Auteurs : A. CURIONI, Auteur ; I. MINIO-PALUELLO, Auteur ; L. M. SACHELI, Auteur ; M. CANDIDI, Auteur ; S. M. AGLIOTI, Auteur Article en page(s) : 23p. Langues : Anglais (eng) Mots-clés : Autism Cooperation Coordination strategies Interpersonal coordination Joint actions Role taking Index. décimale : PER Périodiques Résumé : BACKGROUND: Despite the fact that deficits in social communication and interaction are at the core of Autism Spectrum Conditions (ASC), no study has yet tested individuals on a continuum from neurotypical development to autism in an on-line, cooperative, joint action task. In our study, we aimed to assess whether the degree of autistic traits affects participants' ability to modulate their motor behavior while interacting in a Joint Grasping task and according to their given role. METHODS: Sixteen pairs of adult participants played a cooperative social interactive game in which they had to synchronize their reach-to-grasp movements. Pairs were comprised of one ASC and one neurotypical with no cognitive disability. In alternate experimental blocks, one participant knew what action to perform (instructed role) while the other had to infer it from his/her partner's action (adaptive role). When in the adaptive condition, participants were told to respond with an action that was either opposite or similar to their partner. Participants also played a non-social control game in which they had to synchronize with a non-biological stimulus. RESULTS: In the social interactive task, higher degree of autistic traits predicted less ability to modulate joint action according to one's interactive role. In the non-social task, autistic traits did not predict differences in movement preparation and planning, thus ruling out the possibility that social interactive task results were due to basic motor or executive function difficulties. Furthermore, when participants played the non-social game, the higher their autistic traits, the more they were interfered by the non-biological stimulus. CONCLUSIONS: Our study shows for the first time that high autistic traits predict a stereotypical interaction style when individuals are required to modulate their movements in order to coordinate with their partner according to their role in a joint action task. Specifically, the infrequent emergence of role-based motor behavior modulation during on-line motor cooperation in participants with high autistic traits sheds light on the numerous difficulties ASC have in nonverbal social interactions.

Titre : Computer Vision Analysis of Reduced Interpersonal Affect Coordination in Youth With Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Casey J. ZAMPELLA, Auteur ; Loisa BENNETTO, Auteur ; John D. HERRINGTON, Auteur Article en page(s) : p.2133-2142 Langues : Anglais (eng) Mots-clés : affect/emotion computer vision facial expression interpersonal coordination social-emotional reciprocity synchrony Index. décimale : PER Périodiques Résumé : Atypical social-emotional reciprocity is a core feature of autism spectrum disorder (ASD) but can be difficult to operationalize. One measurable manifestation of reciprocity may be interpersonal coordination, the tendency to align the form and timing of one's behaviors (including facial affect) with others. Interpersonal affect coordination facilitates sharing and understanding of emotional cues, and there is evidence that it is reduced in ASD. However, most research has not measured this process in true social contexts, due in part to a lack of tools for measuring dynamic facial expressions over the course of an interaction. Automated facial analysis via computer vision provides an efficient, granular, objective method for measuring naturally occurring facial affect and coordination. Youth with ASD and matched typically developing youth participated in cooperative conversations with their mothers and unfamiliar adults. Time-synchronized videos were analyzed with an open-source computer vision toolkit for automated facial analysis, for the presence and intensity of facial movements associated with positive affect. Both youth and adult conversation partners exhibited less positive affect during conversations when the youth partner had ASD. Youth with ASD also engaged in less affect coordination over the course of conversations. When considered dimensionally across youth with and without ASD, affect coordination significantly predicted scores on rating scales of autism-related social atypicality, adaptive social skills, and empathy. Findings suggest that affect coordination is an important interpersonal process with implications for broader social-emotional functioning. This preliminary study introduces a promising novel method for quantifying moment-to-moment facial expression and emotional reciprocity during natural interactions. LAY SUMMARY: This study introduces a novel, automated method for measuring social-emotional reciprocity during natural conversations, which may improve assessment of this core autism diagnostic behavior. We used computerized methods to measure facial affect and the degree of affect coordination between conversation partners. Youth with autism displayed reduced affect coordination, and reduced affect coordination predicted lower scores on measures of broader social-emotional skills.

Titre : Reduced nonverbal interpersonal synchrony in autism spectrum disorder independent of partner diagnosis: a motion energy study Type de document : Texte imprimé et/ou numérique Auteurs : Alexandra Livia GEORGESCU, Auteur ; S. KOEROGLU, Auteur ; Antonia HAMILTON, Auteur ; Kai VOGELEY, Auteur ; C. M. FALTER-WAGNER, Auteur ; W. TSCHACHER, Auteur Article en page(s) : 11 p. Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Autism spectrum disorders Conversation Dyadic interactions Interactional heterogeneity Interpersonal coordination Interpersonal synchrony Motion energy Motion energy analysis Nonverbal behaviour Social interaction Index. décimale : PER Périodiques Résumé : BACKGROUND: One of the main diagnostic features of individuals with autism spectrum disorders is nonverbal behaviour difficulties during naturalistic social interactions. The 'Interactional Heterogeneity Hypothesis' of ASD proposes that the degree to which individuals share a common ground substantially influences their ability to achieve smooth social interactions. METHODS: To test this hypothesis, we filmed 29 autistic and 29 matched typically developed adults engaged in several conversational tasks. Windowed cross-lagged correlations were computed using the time series of motion energy of both individuals in a dyad. These coefficients were then compared across the three dyad types that were homo- or heterogenous with respect to diagnosis: pairs of two autistic individuals, two typically developed individuals or pairs of one autistic and one typically developed person. RESULTS: We found that all dyad types achieved above-chance interpersonal synchrony, but that synchrony was more expressed in typical dyads compared to both autistic and mixed dyads. LIMITATIONS: The method presented here provides only one, albeit objective and robust, approach to explore synchrony. The methodological choices as well as the lack of consideration for other communication modalities may limit our interpretation of the findings. Moreover, the sample size is small with respect to exploring associations between synchrony and various outcome and social skill measures. CONCLUSIONS: The present results do not provide support for the Interactional Heterogeneity Hypothesis given that autistic individuals do not coordinate better when interacting with another autistic individual, compared to when interacting with a typical individual.
