Mimicry and social affiliation with virtual partner are decreased in autism / Bahar TUNCGENC in Research in Autism Spectrum Disorders, 100 (February 2023)
[article]
Titre : Mimicry and social affiliation with virtual partner are decreased in autism Type de document : Texte imprimé et/ou numérique Auteurs : Bahar TUNCGENC, Auteur ; Carolyn KOCH, Auteur ; Inge-Marie EIGSTI, Auteur ; Stewart H. MOSTOFSKY, Auteur Article en page(s) : 102073 Langues : Anglais (eng) Mots-clés : Mimicry Social affiliation Social interactions Autism Children Index. décimale : PER Périodiques Résumé : Copying other people’s mannerisms (i.e., mimicry) occurs spontaneously during social interactions, and is thought to contribute to sharing emotions, affiliation with partners and interaction quality. While previous research shows decreased mimicry of emotional facial expressions in autism spectrum disorders (ASD), we know relatively little about how non-emotional, non-facial behavioural mimicry manifests and, more importantly, what it means for autistic individuals’ social interactions. In a controlled, semi-naturalistic interaction setting, this study examined how often autistic and neurotypical (NT) children mimicked a virtual partner’s non-facial mannerisms as they engaged in an interactive story-telling activity. Subsequently, children reported how affiliated they felt towards their interaction partner using an established implicit measure of closeness and a set of questions. Results revealed reduced mimicry (p = .001, φ = 0.38) and less affiliation (p = .01, φ = 0.33) in ASD relative to NT children. Mimicry was associated with affiliation for NT (r(23) = 0.64, p = .0009), but not ASD, children (r(31) = 0.07, p = .72). These results suggest an autism-associated reduction in mimicry and that mimicry during social interactions may not substantially contribute to affiliation in autism.

Titre : Reduced Mimicry to Virtual Reality Avatars in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Paul A. G. FORBES, Auteur ; Xueni PAN, Auteur ; Antonia HAMILTON, Auteur Article en page(s) : p.3788-3797 Langues : Anglais (eng) Mots-clés : Mimicry Virtual reality Social cognition Kinematics Imitation Index. décimale : PER Périodiques Résumé : Mimicry involves unconsciously copying the actions of others. Increasing evidence suggests that autistic people can copy the goal of an observed action but show differences in their mimicry. We investigated mimicry in autism spectrum disorder (ASD) within a two-dimensional virtual reality environment. Participants played an imitation game with a socially engaged avatar and socially disengaged avatar. Despite being told only to copy the goal of the observed action, autistic participants and matched neurotypical participants mimicked the kinematics of the avatars’ movements. However, autistic participants mimicked less. Social engagement did not modulate mimicry in either group. The results demonstrate the feasibility of using virtual reality to induce mimicry and suggest mimicry differences in ASD may also occur when interacting with avatars.

Titre : Autistic Traits Modulate Mimicry of Social but not Nonsocial Rewards Type de document : Texte imprimé et/ou numérique Auteurs : Anthony HAFFEY, Auteur ; Clare PRESS, Auteur ; Garret O'CONNELL, Auteur ; Bhismadev CHAKRABARTI, Auteur Année de publication : 2013 Article en page(s) : p.614-620 Langues : Anglais (eng) Mots-clés : reward imitation social nonsocial autism empathy mimicry Index. décimale : PER Périodiques Résumé : Autism Spectrum Conditions (ASC) are associated with diminished responsiveness to social stimuli, and especially to social rewards such as smiles. Atypical responsiveness to social rewards, which reinforce socially appropriate behavior in children, can potentially lead to a cascade of deficits in social behavior. Individuals with ASC often show diminished spontaneous mimicry of social stimuli in a natural setting. In the general population, mimicry is modulated both by the reward value and the sociality of the stimulus (i.e., whether the stimulus is perceived to belong to a conspecific or an inanimate object). Since empathy and autistic traits are distributed continuously in the general population, this study aimed to test if and how these traits modulated automatic mimicry of rewarded social and nonsocial stimuli. High and low rewards were associated with human and robot hands using a conditioned learning paradigm. Thirty-six participants from the general population then completed a mimicry task involving performing a prespecified hand movement which was either compatible or incompatible with a hand movement presented to the participant. High autistic traits (measured using the Autism Spectrum Quotient, AQ) predicted lesser mimicry of high-reward than low-reward conditioned human hands, whereas trait empathy showed an opposite pattern of correlations. No such relations were observed for high-reward vs. low-reward conditioned robot hands. These results demonstrate how autistic traits and empathy modulate the effects of reward on mimicry of social compared to nonsocial stimuli. This evidence suggests a potential role for the reward system in underlying the atypical social behavior in individuals with ASC, who constitute the extreme end of the spectrum of autistic traits.

Titre : Emulation and Mimicry in School Students with Typical Development and with High Functioning Autism Type de document : Texte imprimé et/ou numérique Auteurs : Luis JIMENEZ, Auteur ; María José LORDA, Auteur ; Cástor MENDEZ, Auteur Article en page(s) : p.1597-1608 Langues : Anglais (eng) Mots-clés : Imitation Mimicry Emulation Automatic imitation Overimitation Index. décimale : PER Périodiques Résumé : Two samples of participants with typical development (TD) and high functioning autism performed an imitation task where the goal was of high or low salience, and where the modeled action complied with or was contrary to the end-state comfort (ESC) effect. Imitation was affected by the ESC effect in both groups, and participants with autism reproduced high salient goals as frequently as did participants with TD, but they reproduced less of the low salient goals. Participants with autism showed a reduced tendency to reproduce those actions which were relatively inefficient to reach the goals. The results are discussed in terms of either a relative imbalance between emulation and mimicry in autism, or a reduced tendency to overimitate.
