Intact mirror mechanisms for automatic facial emotions in children and adolescents with autism spectrum disorder / Martin SCHULTE-RUTHER in Autism Research, 10-2 (February 2017)
[article]
Titre : Intact mirror mechanisms for automatic facial emotions in children and adolescents with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Martin SCHULTE-RUTHER, Auteur ; Ellen OTTE, Auteur ; Kübra ADIGÜZEL, Auteur ; Christine FIRK, Auteur ; Beate HERPERTZ-DAHLMANN, Auteur ; Iring KOCH, Auteur ; Kerstin KONRAD, Auteur Article en page(s) : p.298-310 Langues : Anglais (eng) Mots-clés : mirror neuron system electromyography imitation autism perception action compatibility facial emotions Index. décimale : PER Périodiques Résumé : It has been suggested that an early deficit in the human mirror neuron system (MNS) is an important feature of autism. Recent findings related to simple hand and finger movements do not support a general dysfunction of the MNS in autism. Studies investigating facial actions (e.g., emotional expressions) have been more consistent, however, mostly relied on passive observation tasks. We used a new variant of a compatibility task for the assessment of automatic facial mimicry responses that allowed for simultaneous control of attention to facial stimuli. We used facial electromyography in 18 children and adolescents with Autism spectrum disorder (ASD) and 18 typically developing controls (TDCs). We observed a robust compatibility effect in ASD, that is, the execution of a facial expression was facilitated if a congruent facial expression was observed. Time course analysis of RT distributions and comparison to a classic compatibility task (symbolic Simon task) revealed that the facial compatibility effect appeared early and increased with time, suggesting fast and sustained activation of motor codes during observation of facial expressions. We observed a negative correlation of the compatibility effect with age across participants and in ASD, and a positive correlation between self-rated empathy and congruency for smiling faces in TDC but not in ASD. This pattern of results suggests that basic motor mimicry is intact in ASD, but is not associated with complex social cognitive abilities such as emotion understanding and empathy.

MCPARTLAND, Auteur ; Martha D. KAISER, Auteur ; Robert T. SCHULTZ, Auteur Article en page(s) : p.1259-1267 Langues : Anglais (eng) Mots-clés : ASD computer-based assessment facial emotions perceptual skills social communication Index. décimale : PER Périodiques Résumé : Background: Although impaired social?emotional ability is a hallmark of autism spectrum disorder (ASD), the perceptual skills and mediating strategies contributing to the social deficits of autism are not well understood. A perceptual skill that is fundamental to effective social communication is the ability to accurately perceive and interpret facial emotions. To evaluate the expression processing of participants with ASD, we designed the Let?s Face It! Emotion Skills Battery (LFI! Battery), a computer-based assessment composed of three subscales measuring verbal and perceptual skills implicated in the recognition of facial emotions. Methods: We administered the LFI! Battery to groups of participants with ASD and typically developing control (TDC) participants that were matched for age and IQ. Results: On the Name Game labeling task, participants with ASD (N = 68) performed on par with TDC individuals (N = 66) in their ability to name the facial emotions of happy, sad, disgust and surprise and were only impaired in their ability to identify the angry expression. On the Matchmaker Expression task that measures the recognition of facial emotions across different facial identities, the ASD participants (N = 66) performed reliably worse than TDC participants (N = 67) on the emotions of happy, sad, disgust, frighten and angry. In the Parts?Wholes test of perceptual strategies of expression, the TDC participants (N = 67) displayed more holistic encoding for the eyes than the mouths in expressive faces whereas ASD participants (N = 66) exhibited the reverse pattern of holistic recognition for the mouth and analytic recognition of the eyes. Conclusion: In summary, findings from the LFI! Battery show that participants with ASD were able to label the basic facial emotions (with the exception of angry expression) on par with age- and IQ-matched TDC participants. However, participants with ASD were impaired in their ability to generalize facial emotions across different identities and showed a tendency to recognize the mouth feature holistically and the eyes as isolated parts.
