Visual Search in ASD: Instructed Versus Spontaneous Local and Global Processing / Ruth VAN DER HALLEN in Journal of Autism and Developmental Disorders, 46-9 (September 2016)
[article]
Titre : Visual Search in ASD: Instructed Versus Spontaneous Local and Global Processing Type de document : Texte imprimé et/ou numérique Auteurs : Ruth VAN DER HALLEN, Auteur ; Kris EVERS, Auteur ; Bart BOETS, Auteur ; Jean STEYAERT, Auteur ; Ilse NOENS, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.3023-3036 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD) Visual search Local–global Interference Task instruction Gabor Index. décimale : PER Périodiques Résumé : Visual search has been used extensively to investigate differences in mid-level visual processing between individuals with ASD and TD individuals. The current study employed two visual search paradigms with Gaborized stimuli to assess the impact of task distractors (Experiment 1) and task instruction (Experiment 2) on local–global visual processing in ASD versus TD children. Experiment 1 revealed both groups to be equally sensitive to the absence or presence of a distractor, regardless of the type of target or type of distractor. Experiment 2 revealed a differential effect of task instruction for ASD compared to TD, regardless of the type of target. Taken together, these results stress the importance of task factors in the study of local–global visual processing in ASD.
