Weaker face recognition in adults with autism arises from perceptually based alterations / Marissa HARTSTON in Autism Research, 16-4 (April 2023)
[article]
Titre : Weaker face recognition in adults with autism arises from perceptually based alterations Type de document : Texte imprimé et/ou numérique Auteurs : Marissa HARTSTON, Auteur ; Galia AVIDAN, Auteur ; Yoni PERTZOV, Auteur ; Bat-Sheva HADAD, Auteur Article en page(s) : p.723-733 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Face recognition has been shown to be impaired in autism spectrum disorders (ASD). However, it is still debated whether these face processing deficits arise from perceptually based alterations. We tested individuals with ASD and matched typically developing (TD) individuals using a delayed estimation task in which a single target face was shown either upright or inverted. Participants selected a face that best resembled the target face out of a cyclic space of morphed faces. To enable the disentanglement of visual from mnemonic processing, reports were required either following a 1 and 6 second retention interval, or simultaneously while the target face was still visible. Individuals with ASD made significantly more errors than TD individuals in both the simultaneous and delayed intervals, indicating that face recognition deficits in autism are also perceptual rather than strictly memory based. Moreover, individuals with ASD exhibited weaker inversion effects than the TD individuals, on all retention intervals. This finding, that was mostly evident in precision errors, suggests that contrary to the more precise representations of upright faces in TD individuals, individuals with ASD exhibit similar levels of precision for inverted and upright faces, for both simultaneous and delayed conditions. These results suggest that weakened memory for faces reported in ASD may be secondary to an underlying perceptual deficit in face processing.
