Operationalizing atypical gaze in toddlers with autism spectrum disorders: a cohesion-based approach / Q. WANG in Molecular Autism, 9 (2018)
[article]
Titre : Operationalizing atypical gaze in toddlers with autism spectrum disorders: a cohesion-based approach Type de document : Texte imprimé et/ou numérique Auteurs : Q. WANG, Auteur ; Daniel J. CAMPBELL, Auteur ; S. L. MACARI, Auteur ; Katarzyna CHAWARSKA, Auteur ; F. SHIC, Auteur Article en page(s) : 25p. Langues : Anglais (eng) Mots-clés : Attention Autism Spectrum Disorder/diagnosis/physiopathology Case-Control Studies Child, Preschool Female Fixation, Ocular Humans Infant Male Social Behavior Visual Perception asd Attentional synchrony Atypicality Autism Cohesion Eye tracking Visual attention Index. décimale : PER Périodiques Résumé : Background: Multiple eye-tracking studies have highlighted the "atypical" nature of social attention in autism. However, it is unclear how "atypical" or "typical" should be quantified. Methods: We developed a method for identifying moments when members of a group looked at similar places (High-Cohesion Time Frames; HCTFs). We defined typicality as the proximity of gaze points to typically developing (TD) gaze points during TD HCTFs. Comparing toddlers with ASD (n = 112) to developmentally delayed (DD, n = 36) and TD (n = 163) toddlers during a video with Dyadic Bid, Sandwich-Making, Joint Attention, and Animated Toys conditions, we examined (a) individual typicality scores, (b) the relationship between typicality and symptom severity, and (c) HCTF distributions associated with each diagnostic group. Results: The ASD group had lower gaze typicality scores compared to the TD and DD groups in the Dyadic Bid and Sandwich-Making conditions but not during Animated Toys. The DD and TD groups did not differ in any condition. Correlational analyses indicated that higher typicality scores were associated with increased looking at pre-planned locations of the scene indexed by each experimental condition. In the ASD group, lower gaze typicality was associated with more severe autism symptoms. Examining ASD HCTFs, the gaze of toddlers with ASD was least cohesive during Dyadic Bid and most cohesive during Animated Toys. Conclusion: In contrast to non-ASD groups, toddlers with ASD show high cohesion during salient nonsocial events, suggesting that consistency in looking strategies may depend more on perceptual features. These findings are consequential for understanding individual differences in visual attention in ASD and for the design of more sensitive biomarker tasks for stratification, between-group differentiation, and measuring response to treatment.

Narrative competence and internal state language (ISL) was investigated using narrations elicited by a wordless picture book. 11 girls and 11 boys with ASD and 11 typically developing girls were individually matched. Although results demonstrate largely comparable narrative skills across groups, the groups differed with respect to the size and use of ISL: Girls with ASD verbalized and motivated internal states more often than boys, and both groups with ASD fell behind typically developing children in production of affective words. Implications for the clinical presentation of males and females with ASD are discussed.
