Do children with and without autism spectrum disorder use different visuospatial processing skills to perform the Rey-Osterrieth complex figure test? / Ramona CARDILLO in Autism Research, 15-7 (July 2022)
[article]
Titre : Do children with and without autism spectrum disorder use different visuospatial processing skills to perform the Rey-Osterrieth complex figure test? Type de document : Texte imprimé et/ou numérique Auteurs : Ramona CARDILLO, Auteur ; Rachele LIEVORE, Auteur ; Irene C. MAMMARELLA, Auteur Article en page(s) : p.1311-1323 Langues : Anglais (eng) Mots-clés : Rey-Osterrieth complex figure autism spectrum disorder local/global processing visuospatial organization abilities visuospatial skills Index. décimale : PER Périodiques Résumé : Visuospatial organization abilities are closely related to other visuospatial processing skills, such as visuomotor coordination, perceptual abilities, mental rotation, and working memory (WM). One task that enables visuospatial organization abilities to be investigated is the Rey-Osterrieth complex figure test (ROCFT). When examining visuospatial functioning, individuals with autism spectrum disorder (ASD) have proved capable of operating both locally and globally, depending on the sub-domain embraced, with a preference for a locally-oriented processing of visuospatial information. The present research aimed to establish whether different underlying visuospatial skills might account for performance in the ROCFT in children and adolescents with ASD, compared with typically developing (TD), by considering the role of local/global visuospatial processing. The study involved 39 participants who have ASD without intellectual disability, and 57 TD aged 8-16?years. The participants were administered tasks assessing visuospatial organization abilities, manual dexterity, visual perception, mental rotation, spatial-sequential, spatial-simultaneous WM, and visuospatial processing. Our results suggest that manual dexterity and visuospatial processing similarly explain performance in both groups, while differences in visuospatial WM account for the two groups' visuospatial organization abilities. Spatial-simultaneous WM predicted performance in copy and recall conditions in the TD group but not in the ASD group, while spatial-sequential WM only did so in the latter group, reinforcing the tendency of children with ASD towards local bias in the visuospatial organization domain. The implications of these findings are discussed. LAY SUMMARY: The visuospatial organization abilities of children and adolescents with and without autism were compared, considering their underlying visuospatial skills. Visuospatial organization impairments emerged for children with autism, who differed from typically developing children in the underlying visuospatial skills involved. Given the crucial role of visuospatial organization abilities in everyday life, our results could inspire practitioners to develop training interventions that take into account the strengths and weaknesses of individuals with autism.

Titre : In the Eye of the Beholder: Rapid Visual Perception of Real-Life Scenes by Young Adults with and Without ASD Type de document : Texte imprimé et/ou numérique Auteurs : Steven VANMARCKE, Auteur ; Caitlin MULLIN, Auteur ; Ruth VAN DER HALLEN, Auteur ; Kris EVERS, Auteur ; Ilse NOENS, Auteur ; Jean STEYAERT, Auteur ; Johan WAGEMANS, Auteur Article en page(s) : p.2635-2652 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Rapid visual perception Local/global processing Open-encoding Semantic processing Index. décimale : PER Périodiques Résumé : Typically developing (TD) adults are able to extract global information from natural images and to categorize them within a single glance. This study aimed at extending these findings to individuals with autism spectrum disorder (ASD) using a free description open-encoding paradigm. Participants were asked to freely describe what they saw when looking at briefly presented real-life photographs. Our results show subtle but consistent group-level differences. More specifically, individuals with ASD spontaneously reported the presence of people in the display less frequently than TD participants, and they grasped the gist of the scene less well. These findings argue for a less efficient rapid feedforward processing of global semantic aspects and a less spontaneous interpretation of socially salient information in ASD.
