Aperçu: G.M.
La
présente étude a exploré les altérations liées aux TSA dans la
perception des émotions exprimées par les mouvements du corps. 16
participants avec un diagnostic de TSA et 16 contrôles sans TSA ont observé des scènes
vidéo d'interactions humaines véhiculées par des écrans à points
lumineux.
Les
résultats ont montré que les participants sans TSA ont évalué les
interactions émotionnelles présentant une émotivité positive comme étant
plus intenses et plus confiant quant à leur évaluation que les sujets avec TSA . Les résultats confirment l'idée que les patients avec un diagnostic de TSA ont une perception altérée des émotions. Cela étend la recherche sur les caractéristiques subjectives
(intensité, confiance) de la perception de l'émotion au domaine des
mouvements du corps émotionnel et de la cinématique.

Abstract
One major characteristic of autism spectrum disorder
(ASD) is problems with social interaction and communication. The
present study explored ASD-related alterations in perceiving emotions
expressed via body movements. 16 participants with ASD and 16 healthy
controls observed video scenes of human interactions conveyed by
point-light displays. They rated the valence of the depicted emotions in
terms of their intensity and judged their confidence in their ratings.
Results showed that healthy participants rated emotional interactions
displaying positive emotionality as being more intense and were more
confident about their ratings than ASD subjects. Results support the
idea that patients with ASD have an altered perception of emotions. This
extends research on subjective features (intensity, confidence) of
emotion perception to the domain of emotional body movements and
kinematics.
