Autistic adults exhibit a typical search advantage for facing dyads / Tim VESTNER in Autism Research, 17-12 (December 2024)

These results suggest that facing dyads may compete for observers' attention more effectively than non-facing dyads. In principle, such an advantage might aid the detection of social interactions and facilitate social learning. Autistic individuals are known to exhibit differences in visual processing that impede their perception of other individuals. At present, however, little is known about multi-actor visual processing in autism. Here, we sought to determine whether autistic individuals show a typical search advantage for facing dyads. In an online study, autistic and non-autistic participants were tasked with finding target dyads (pairs of faces arranged face-to-face or back-to-back) embedded among distractor dyads (pairs of faces arranged face-to-back). Relative to the non-autistic controls, the autistic participants took slightly longer to locate target dyads. However, a clear and comparable search advantage for facing dyads was seen in both participant groups. This preliminary evidence suggests that multi-actor processing of autistic participants exhibits typical sensitivity to dyadic arrangement.

Autistic adults exhibit typical sensitivity to changes in interpersonal distance / Bayparvah Kaur GEHDU ; Clare PRESS ; Katie L. H. GRAY ; Richard COOK in Autism Research, 17-7 (July 2024)  

Public ISBD [article]  inAutism Research > 17-7 (July 2024) . - p.1464-1474 Titre : Autistic adults exhibit typical sensitivity to changes in interpersonal distance Type de document : Texte imprimé et/ou numérique Auteurs : Bayparvah Kaur GEHDU, Auteur ; Clare PRESS, Auteur ; Katie L. H. GRAY, Auteur ; Richard COOK, Auteur Article en page(s) : p.1464-1474 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract The visual processing differences seen in autism often impede individuals' visual perception of the social world. In particular, many autistic people exhibit poor face recognition. Here, we sought to determine whether autistic adults also show impaired perception of dyadic social interactions-a class of stimulus thought to engage face-like visual processing. Our focus was the perception of interpersonal distance. Participants completed distance change detection tasks, in which they had to make perceptual decisions about the distance between two actors. On half of the trials, participants judged whether the actors moved closer together; on the other half, whether they moved further apart. In a nonsocial control task, participants made similar judgments about two grandfather clocks. We also assessed participants' face recognition ability using standardized measures. The autistic and nonautistic observers showed similar levels of perceptual sensitivity to changes in interpersonal distance when viewing social interactions. As expected, however, the autistic observers showed clear signs of impaired face recognition. Despite putative similarities between the visual processing of faces and dyadic social interactions, our results suggest that these two facets of social vision may dissociate.
