Impaired Overt Facial Mimicry in Response to Dynamic Facial Expressions in High-Functioning Autism Spectrum Disorders / Sayaka YOSHIMURA in Journal of Autism and Developmental Disorders, 45-5 (May 2015)
[article]
Titre : Impaired Overt Facial Mimicry in Response to Dynamic Facial Expressions in High-Functioning Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Sayaka YOSHIMURA, Auteur ; Wataru SATO, Auteur ; Shota UONO, Auteur ; Motomi TOICHI, Auteur Article en page(s) : p.1318-1328 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders (ASD) Dynamic facial expression Facial mimicry Reciprocal social interaction Index. décimale : PER Périodiques Résumé : Previous electromyographic studies have reported that individuals with autism spectrum disorders (ASD) exhibited atypical patterns of facial muscle activity in response to facial expression stimuli. However, whether such activity is expressed in visible facial mimicry remains unknown. To investigate this issue, we videotaped facial responses in high-functioning individuals with ASD and controls to dynamic and static facial expressions of anger and happiness. Visual coding of facial muscle activity and the subjective impression ratings showed reduced congruent responses to dynamic expressions in the ASD group. Additionally, this decline was related to social dysfunction. These results suggest that impairment in overt facial mimicry in response to others’ dynamic facial expressions may underlie difficulties in reciprocal social interaction among individuals with ASD.

Titre : Investigating automatic emotion processing in boys with autism via eye tracking and facial mimicry recordings Type de document : Texte imprimé et/ou numérique Auteurs : S. VAN DER DONCK, Auteur ; S. VETTORI, Auteur ; M. DZHELYOVA, Auteur ; S. S. MAHDI, Auteur ; P. CLAES, Auteur ; J. STEYAERT, Auteur ; Bart BOETS, Auteur Article en page(s) : p.1404-1420 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/complications Autistic Disorder/complications Child Emotions Eye-Tracking Technology Facial Expression Facial Recognition Humans Male autism spectrum disorder emotion processing eye tracking facial expression recognition facial mimicry Index. décimale : PER Périodiques Résumé : Difficulties in automatic emotion processing in individuals with autism spectrum disorder (ASD) might remain concealed in behavioral studies due to compensatory strategies. To gain more insight in the mechanisms underlying facial emotion recognition, we recorded eye tracking and facial mimicry data of 20 school-aged boys with ASD and 20 matched typically developing controls while performing an explicit emotion recognition task. Proportional looking times to specific face regions (eyes, nose, and mouth) and face exploration dynamics were analyzed. In addition, facial mimicry was assessed. Boys with ASD and controls were equally capable to recognize expressions and did not differ in proportional looking times, and number and duration of fixations. Yet, specific facial expressions elicited particular gaze patterns, especially within the control group. Both groups showed similar face scanning dynamics, although boys with ASD demonstrated smaller saccadic amplitudes. Regarding the facial mimicry, we found no emotion specific facial responses and no group differences in the responses to the displayed facial expressions. Our results indicate that boys with and without ASD employ similar eye gaze strategies to recognize facial expressions. Smaller saccadic amplitudes in boys with ASD might indicate a less exploratory face processing strategy. Yet, this slightly more persistent visual scanning behavior in boys with ASD does not imply less efficient emotion information processing, given the similar behavioral performance. Results on the facial mimicry data indicate similar facial responses to emotional faces in boys with and without ASD. LAY SUMMARY: We investigated (i) whether boys with and without autism apply different face exploration strategies when recognizing facial expressions and (ii) whether they mimic the displayed facial expression to a similar extent. We found that boys with and without ASD recognize facial expressions equally well, and that both groups show similar facial reactions to the displayed facial emotions. Yet, boys with ASD visually explored the faces slightly less than the boys without ASD.

DESCHAMPS, Auteur ; L. COPPES, Auteur ; J. L. KENEMANS, Auteur ; D. J. L. G. SCHUTTER, Auteur ; W. MATTHYS, Auteur Article en page(s) : p.354-362 Langues : Anglais (eng) Mots-clés : Children Emotional responsiveness Facial mimicry ASD Index. décimale : PER Périodiques Résumé : This study aimed to examine facial mimicry in 6–7 year old children with autism spectrum disorder (ASD) and to explore whether facial mimicry was related to the severity of impairment in social responsiveness. Facial electromyographic activity in response to angry, fearful, sad and happy facial expressions was recorded in twenty 6–7 year old children with ASD and twenty-seven typically developing children. Even though results did not show differences in facial mimicry between children with ASD and typically developing children, impairment in social responsiveness was significantly associated with reduced fear mimicry in children with ASD. These findings demonstrate normal mimicry in children with ASD as compared to healthy controls, but that in children with ASD the degree of impairments in social responsiveness may be associated with reduced sensitivity to distress signals.
