Global Visual Processing and Self-Rated Autistic-like Traits / Emma J. GRINTER in Journal of Autism and Developmental Disorders, 39-9 (September 2009)
[article]
Titre : Global Visual Processing and Self-Rated Autistic-like Traits Type de document : Texte imprimé et/ou numérique Auteurs : Emma J. GRINTER, Auteur ; Murray T. MAYBERY, Auteur ; Pia L. VAN BEEK, Auteur ; David R. BADCOCK, Auteur ; Elizabeth PELLICANO, Auteur ; Johanna C. BADCOCK, Auteur Année de publication : 2009 Article en page(s) : p.1278-1290 Langues : Anglais (eng) Mots-clés : Autistic-like-traits Autism-Visual-perception Dorsal-pathway Ventral-pathway Weak-Central-Coherence Index. décimale : PER Périodiques Résumé : The current research investigated, firstly, whether individuals with high levels of mild autistic-like traits display a similar profile of embedded figures test (EFT) and global motion performance to that seen in autism. Secondly, whether differences in EFT performance are related to enhanced local processing or reduced global processing in the ventral visual stream was also examined. Results indicated that people who scored high on the Autism-spectrum Quotient (AQ) were faster to identify embedded figures, and had poorer global motion and global form thresholds than low AQ scorers. However, the two groups did not differ on a task assessing lower-level input to the ventral stream. Overall the results indicate that individuals with high levels of autistic-like traits have difficulties with global integration in the visual pathways, which may at least partly explain their superior EFT performance.
