‘Subtypes’ in the Presentation of Autistic Traits in the General Adult Population / Colin J. PALMER in Journal of Autism and Developmental Disorders, 45-5 (May 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-5 (May 2015) . - p.1291-1301 Titre : ‘Subtypes’ in the Presentation of Autistic Traits in the General Adult Population Type de document : Texte imprimé et/ou numérique Auteurs : Colin J. PALMER, Auteur ; Bryan PATON, Auteur ; Peter G. ENTICOTT, Auteur ; Jakob HOHWY, Auteur Article en page(s) : p.1291-1301 Langues : Anglais (eng) Mots-clés : Autistic traits  Autism-spectrum quotient  Cluster analysis  Subgroups  Factor analysis Index. décimale : PER Périodiques Résumé : The present study examined the presentation of autistic traits in a large adult population sample (n = 2,343). Cluster analysis indicated two subgroups with clearly distinguishable trait profiles. One group (n = 1,059) reported greater social difficulties and lower detail orientation, while the second group (n = 1,284) reported lesser social difficulties and greater detail orientation. We also report a three-factor solution for the autism-spectrum quotient, with two, related, social-themed factors (Sociability and Mentalising) and a third non-social factor that varied independently (Detail Orientation). These results indicate that different profiles of autistic characteristics tend to occur in the adult nonclinical population. Research into nonclinical variance in autistic features may benefit by considering social- and detail-related trait domains independently.

The Rubber Hand Illusion Reveals Proprioceptive and Sensorimotor Differences in Autism Spectrum Disorders / Bryan PATON in Journal of Autism and Developmental Disorders, 42-9 (September 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-9 (September 2012) . - p.1870-1883 Titre : The Rubber Hand Illusion Reveals Proprioceptive and Sensorimotor Differences in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Bryan PATON, Auteur ; Jakob HOHWY, Auteur ; Peter G. ENTICOTT, Auteur Année de publication : 2012 Article en page(s) : p.1870-1883 Langues : Anglais (eng) Mots-clés : High-functioning autism spectrum disorder  Rubber hand illusion  Multimodal sensory integration  Local processing bias Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is characterised by differences in unimodal and multimodal sensory and proprioceptive processing, with complex biases towards local over global processing. Many of these elements are implicated in versions of the rubber hand illusion (RHI), which were therefore studied in high-functioning individuals with ASD and a typically developing control group. Both groups experienced the illusion. A number of differences were found, related to proprioception and sensorimotor processes. The ASD group showed reduced sensitivity to visuotactile-proprioceptive discrepancy but more accurate proprioception. This group also differed on acceleration in subsequent reach trials. Results are discussed in terms of weak top-down integration and precision-accuracy trade-offs. The RHI appears to be a useful tool for investigating multisensory processing in ASD.
