Using a Posner-type paradigm, a centrally located display indicated the location of a forthcoming target on 80 % of trials and the opposite location on 20 % of trials. TD children, but not children with ASD, were faster to identify a validly cued target than an invalidly cued target. A scrambled version of the point-light pointing gesture, retaining individual dot speed and direction of movement but not the configuration, produced no validity effect in either group. A video of a pointing gesture produced validity effects in both groups.

Young Children with Autism Spectrum Disorder Do Not Preferentially Attend to Biological Motion / Dagmara ANNAZ in Journal of Autism and Developmental Disorders, 42-3 (March 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-3 (March 2012) . - p.401-408 Titre : Young Children with Autism Spectrum Disorder Do Not Preferentially Attend to Biological Motion Type de document : Texte imprimé et/ou numérique Auteurs : Dagmara ANNAZ, Auteur ; Ruth CAMPBELL, Auteur ; Mike COLEMAN, Auteur ; Elizabeth MILNE, Auteur ; John SWETTENHAM, Auteur Année de publication : 2012 Article en page(s) : p.401-408 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Social stimuli  Attention  Biological motion Index. décimale : PER Périodiques Résumé : Preferential attention to biological motion can be seen in typically developing infants in the first few days of life and is thought to be an important precursor in the development of social communication. We examined whether children with autism spectrum disorder (ASD) aged 3–7 years preferentially attend to point-light displays depicting biological motion. We found that children with ASD did not preferentially attend to biological motion over phase-scrambled motion, but did preferentially attend to a point-light display of a spinning top rather than a human walker. In contrast a neurotypical matched control group preferentially attended to the human, biological motion in both conditions. The results suggest a core deficit in attending to biological motion in ASD.
