Brief report: Temporal distribution of visual attention between the eyes and mouth in young autistic children / Fanny STERCQ ; Mikhail KISSINE in Research in Autism Spectrum Disorders, 110 (February 2024)

Titre : Brief report: Temporal distribution of visual attention between the eyes and mouth in young autistic children Type de document : Texte imprimé et/ou numérique Auteurs : Fanny STERCQ, Auteur ; Mikhail KISSINE, Auteur Article en page(s) : p.102292 Mots-clés : Eye-tracking Face scanning Autism Generalized additive mixed effects model Index. décimale : PER Périodiques Résumé : Background Face scanning studies in autistic children report mixed results as to attention allocated to the eyes and mouth regions. While face scanning is a dynamic process, the way autistic children distribute their attention between the eyes and mouth of their interlocutor is usually analyzed by averaging the proportion of time spent looking either on the eyes or the mouth over the whole duration of stimulus presentation. Method In this study, instead, we focused on the temporal distribution of visual attention between the eyes and mouth of adult faces in 58 autistic and 61 typically developing (TD) children. Participants? eye movements were recorded as they were freely watching videos of faces of silent and speaking adults. We explored attention to the eyes and mouth with fine-grained analyses of the temporal trajectory of fixations on the two regions using generalized additive mixed effects models. Results These analyses revealed that both groups started their observation of speaking faces on the eyes and shifted to the mouth as the actor started speaking. However, TD, but not autistic children then slowly shifted their attention back to the eyes. Conclusions Rigorous analyses of how autistic children modulate their visual attention between key social features of the face over time may provide more accurate descriptions of their face scanning abilities.

Titre : No preference for direct versus averted gaze in autistic adults: a reinforced preferential looking paradigm Type de document : Texte imprimé et/ou numérique Auteurs : Elise CLIN, Auteur ; Pauline MAES, Auteur ; Fanny STERCQ, Auteur ; Mikhail KISSINE, Auteur Langues : Anglais (eng) Mots-clés : Adults Alexithymia Autism Eye gaze direction Eye-tracking Gender Reinforced preferential looking paradigm Social anxiety Social attention or publication of this article. Index. décimale : PER Périodiques Résumé : BACKGROUND: With the overarching objective to gain better insights into social attention in autistic adults, the present study addresses three outstanding issues about face processing in autism. First, do autistic adults display a preference for mouths over eyes; second, do they avoid direct gaze; third, is atypical visual exploration of faces in autism mediated by gender, social anxiety or alexithymia? METHODS: We used a novel reinforced preferential looking paradigm with a group of autistic adults (n?=?43, 23 women) pairwise matched on age with neurotypical participants (n?=?43, 21 women). Participants watched 28 different pairs of 5 s video recordings of a speaking person: the two videos, simultaneously displayed on the screen, were identical except that gaze was directed at the camera in one video and averted in the other. After a 680 ms transition phase, a short reinforcement animation appeared on the side that had displayed the direct gaze. RESULTS: None of the groups showed a preference for mouths over eyes. However, neurotypical participants fixated significantly more the stimuli with direct gaze, while no such preference emerged in autistic participants. As the experiment progressed, neurotypical participants also increasingly anticipated the appearance of the reinforcement, based on the location of the stimulus with the direct gaze, while no such anticipation emerged in autistic participants. LIMITATIONS: Our autistic participants scored higher on the social anxiety and alexithymia questionnaires than neurotypicals. Future studies should match neurotypical and autistic participants on social anxiety and alexithymia and complement questionnaires with physiological measures of anxiety. CONCLUSIONS: The absence of preference for direct versus averted gaze in the autistic group is probably due to difficulties in distinguishing eye gaze direction, potentially linked to a reduced spontaneous exploration or avoidance of the eye region. Social attention and preference for direct versus averted gaze correlated with alexithymia and social anxiety scores, but not gender.
