Inversion effects in the perception of the moving human form: A comparison of adolescents with autism spectrum disorder and typically developing adolescents / Laura CLEARY in Autism, 18-8 (November 2014)
[article]
Titre : Inversion effects in the perception of the moving human form: A comparison of adolescents with autism spectrum disorder and typically developing adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Laura CLEARY, Auteur ; Kathy LOONEY, Auteur ; Nuala BRADY, Auteur ; Michael FITZGERALD, Auteur Article en page(s) : p.943-952 Langues : Anglais (eng) Mots-clés : autism spectrum disorders biological motion perception body inversion effect configural processing Index. décimale : PER Périodiques Résumé : The “body inversion effect” refers to superior recognition of upright than inverted images of the human body and indicates typical configural processing. Previous research by Reed et al. using static images of the human body shows that people with autism fail to demonstrate this effect. Using a novel task in which adults, adolescents with autism, and typically developing adolescents judged whether walking stick figures—created from biological motion recordings and shown at seven orientations between 0° and 180°—were normal or distorted, this study shows clear effects of stimulus inversion. Reaction times and “inverse efficiency” increased with orientation for normal but not distorted walkers, and sensitivity declined with rotation from upright for all groups. Notably, the effect of stimulus inversion was equally detrimental to both groups of adolescents suggesting intact configural processing of the body in motion in autism spectrum disorder.
