A degraded sensitivity to facial perceptual cues might contribute to atypical social interactions in autism spectrum disorder (ASD). The current study investigated whether face based social judgment is atypical in ASD and if so, whether it could be related to a degraded sensitivity to facial perceptual cues. Individuals with ASD (n = 33) and IQ- and age-matched controls (n = 38) were enrolled in this study. Watching a series of photographic or synthetic faces, they had to judge them for “kindness”. In synthetic stimuli, the amount of perceptual cues available could be either large or small. We observed that social judgment was atypical in the ASD group on photographic stimuli, but, contrarily to the prediction based on the degraded sensitivity hypothesis, analyses on synthetic stimuli found a similar performance and a similar effect of the amount of perceptual cues in both groups. Further studies on perceptual differences between photographs and synthetic pictures of faces might help understand atypical social judgment in ASD.

Gaze direction detection in autism spectrum disorder / Baudouin FORGEOT D'ARC in Autism, 21-1 (January 2017)  

Public ISBD [article]  inAutism > 21-1 (January 2017) . - p.100-107 Titre : Gaze direction detection in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Baudouin FORGEOT D'ARC, Auteur ; Richard DELORME, Auteur ; Tiziana ZALLA, Auteur ; Aline LEFEBVRE, Auteur ; Frédérique AMSELLEM, Auteur ; Sanaa MOUKAWANE, Auteur ; Laurence LETELLIER, Auteur ; Marion LEBOYER, Auteur ; Marie-Christine MOUREN, Auteur ; Franck RAMUS, Auteur Article en page(s) : p.100-107 Langues : Anglais (eng) Mots-clés : autism  face processing  gaze direction detection  perception  social cognition Index. décimale : PER Périodiques Résumé : Detecting where our partners direct their gaze is an important aspect of social interaction. An atypical gaze processing has been reported in autism. However, it remains controversial whether children and adults with autism spectrum disorder interpret indirect gaze direction with typical accuracy. This study investigated whether the detection of gaze direction toward an object is less accurate in autism spectrum disorder. Individuals with autism spectrum disorder (n?=?33) and intelligence quotients–matched and age-matched controls (n?=?38) were asked to watch a series of synthetic faces looking at objects, and decide which of two objects was looked at. The angle formed by the two possible targets and the face varied following an adaptive procedure, in order to determine individual thresholds. We found that gaze direction detection was less accurate in autism spectrum disorder than in control participants. Our results suggest that the precision of gaze following may be one of the altered processes underlying social interaction difficulties in autism spectrum disorder.

Oculomotor behavior in children with autism spectrum disorders / Simona CALDANI in Autism, 24-3 (April 2020)  

Public ISBD [article]  inAutism > 24-3 (April 2020) . - p.670-679 Titre : Oculomotor behavior in children with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Simona CALDANI, Auteur ; Sarah STEG, Auteur ; Aline LEFEBVRE, Auteur ; Paola ATZORI, Auteur ; Hugo PEYRE, Auteur ; Richard DELORME, Auteur ; Maria Pia BUCCI, Auteur Article en page(s) : p.670-679 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  children  express saccades  inhibitory mechanism  latency Index. décimale : PER Périodiques Résumé : To identify quantitative indicators of social communication dysfunctions, we explored the oculomotor performances in subjects with autism spectrum disorders. Discordant findings in the literature have been reported for oculomotor behavior in subjects with autism spectrum disorders. This study aimed to explore reflexive and voluntary saccadic performance in a group of 32 children with autism spectrum disorders (mean age: 12.1 +/- 0.5 years) compared to 32 age-, sex-, and IQ-matched typically developing children (control group). We used different types of reflexive and voluntary saccades: gap, step, overlap, and anti-saccades. Eye movements were recorded using an eye tracker (Mobile EBT((R))) and we measured latency, percentage of anticipatory and express saccades, errors of anti-saccades and gain. Children with autism spectrum disorders reported similar latency values with respect to typically developing children for reflexive and voluntary saccades; in contrast, they made more express and anticipatory saccades overall, as shown in paradigm testing (gap, step, overlap, and anti-saccades). Our findings support previous evidence of the atypicality of the cortical network, which is involved in saccade triggering and attentional processes in children with autism spectrum disorders.
