Autistic children do not exhibit an own-race advantage as compared to typically developing children / Sarina Hui-Lin CHIEN in Research in Autism Spectrum Disorders, 8-11 (November 2014)

The present study hypothesized that the magnitude of the other-race effect shall be reduced in individuals with ASD owing to their inattention to faces since infancy. Using a sequential face discrimination task, we tested the other-race effect of 18 ASD (mean age = 7.5 years) and 13 age-matched typically developing (TD) children (mean age = 7.6 years). The stimuli were cropped Asian and African faces, each with four levels of difficulty: easy (change identity), medium (replaced eyes), hard-eye (widen eye spacing), and hard-mouth (moved up mouth). The TD children showed a significant own-race advantage such that the best performance was found in the Asian easy condition. The ASD children did not exhibit such advantage at all. Moreover, ASD children showed the highest error rates in the hard-eye condition instead of the hard-mouth condition, indicating insensitivity to eyes region. In sum, our findings support the hypothesis that the other-race effect is reduced in ASD children, reflecting an incomplete development of an expert face system.

Children with autism spectrum disorders are less proficient in action identification and lacking a preference for upright point-light biological motion displays / Liang-Huei WANG in Research in Autism Spectrum Disorders, 11 (March 2015)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 11 (March 2015) . - p.63-76 Titre : Children with autism spectrum disorders are less proficient in action identification and lacking a preference for upright point-light biological motion displays Type de document : Texte imprimé et/ou numérique Auteurs : Liang-Huei WANG, Auteur ; Sarina Hui-Lin CHIEN, Auteur ; Shun-Fu HU, Auteur ; Tzu-Yun CHEN, Auteur ; Hsin-Shui CHEN, Auteur Article en page(s) : p.63-76 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Biological motion  Point-light display  Looking preference Index. décimale : PER Périodiques Résumé : Recent studies demonstrated impaired biological motion perception in children with autism spectrum disorder (ASD), who are characterized by deficits in social interactions and communication. Using point-light displays, the present study intended to examine the looking preferences for human and non-human biological motion paired with non-biological scrambled motion (Exp. 1) and the performance on the action identification task (Exp. 2) in typically developing (TD) children and children with ASD. Forty-two participants (21 ASD and 21 TD children) aged 3–7 years were included in this study. In Exp. 1, we found that children with ASD did not preferentially attend to biological motion as TD children did. The ASD group also exhibited shorter overall fixation time for all the point-light displays than did the TD group. In the action identification task of Exp. 2, children with ASD made more errors in naming and needed more time to respond than did TD children. Nevertheless, the actions that were likely to be correctly identified by TD children were also likely to be correctly identified by children with ASD. In conclusion, children with ASD are lacking the preference TD children have for biological motion stimuli over the scrambled motion. Moreover, such impairment might be due to an overall deficit in processing biological motion information and may explain the poor performance on action recognition in the ASD group.
