Atypical recognition of dynamic changes in facial expressions in autism spectrum disorders / Wataru SATO in Research in Autism Spectrum Disorders, 7-7 (July 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-7 (July 2013) . - p.906-912 Titre : Atypical recognition of dynamic changes in facial expressions in autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Wataru SATO, Auteur ; Shota UONO, Auteur ; Motomi TOICHI, Auteur Article en page(s) : p.906-912 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders (ASD)  Dynamic facial expressions  Naturalness  Speed Index. décimale : PER Périodiques Résumé : Previous studies have suggested that the processing of dynamic facial expressions is impaired in autism spectrum disorders (ASD). However, the specific component that is impaired in the processing of dynamic facial expressions has not been identified. We investigated the recognition of dynamic changes in facial expressions among individuals with ASD and age- and sex-matched typically developing controls. Morphing animations of facial expressions of six emotions were presented at four different changing speeds, and participants rated the naturalness of the expression changes. The correspondence between reduced speeds and decreased naturalness ratings was weaker in the ASD than in the control group. These results suggest that the atypical visual analysis of dynamic changes in facial expressions underlies the impairment in real-life social interaction among individuals with ASD.

Reduced Recognition of Dynamic Facial Emotional Expressions and Emotion-Specific Response Bias in Children with an Autism Spectrum Disorder / Kris EVERS in Journal of Autism and Developmental Disorders, 45-6 (June 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-6 (June 2015) . - p.1774-1784 Titre : Reduced Recognition of Dynamic Facial Emotional Expressions and Emotion-Specific Response Bias in Children with an Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Kris EVERS, Auteur ; Jean STEYAERT, Auteur ; Ilse NOENS, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.1774-1784 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD)  Dynamic facial expressions  Emotion recognition  Face perception  Response bias  Theory of mind Index. décimale : PER Périodiques Résumé : Emotion labelling was evaluated in two matched samples of 6–14-year old children with and without an autism spectrum disorder (ASD; N = 45 and N = 50, resp.), using six dynamic facial expressions. The Emotion Recognition Task proved to be valuable demonstrating subtle emotion recognition difficulties in ASD, as we showed a general poorer emotion recognition performance, in addition to some emotion-specific impairments in the ASD group. Participants’ preference for selecting a certain emotion label, irrespective of the stimulus presented, played an important role in our results: response bias-corrected data still showed an overall decreased emotion recognition performance in ASD, but no emotion-specific impairments anymore. Moreover, ASD traits and empathy were correlated with emotion recognition performance.
