Atypical gaze patterns to facial feature areas in autism spectrum disorders reveal age and culture effects: A meta-analysis of eye-tracking studies / X. MA in Autism Research, 14-12 (December 2021)  

Public ISBD [article]  inAutism Research > 14-12 (December 2021) . - p.2625-2639 Titre : Atypical gaze patterns to facial feature areas in autism spectrum disorders reveal age and culture effects: A meta-analysis of eye-tracking studies Type de document : Texte imprimé et/ou numérique Auteurs : X. MA, Auteur ; H. GU, Auteur ; J. ZHAO, Auteur Article en page(s) : p.2625-2639 Langues : Anglais (eng) Mots-clés : Adult  Autism Spectrum Disorder/complications  Child  Eye-Tracking Technology  Facial Recognition  Fixation, Ocular  Humans  Mouth  autism spectrum disorder  culture  development  face processing  facial features  meta-analysis Index. décimale : PER Périodiques Résumé : Children and adults with autism spectrum disorder (ASD) often present with atypical gaze patterns to others' faces, a finding substantiated throughout the literature. Yet, a quantification of atypical gaze patterns to different facial regions (e.g., eyes versus mouth) in ASD remains controversial. Also few study has investigated how age and culture impacted the pattern of gaze abnormalities in ASD. This research therefore conducted a meta-analysis of eye-tracking studies to evaluate age and culture effect on atypical gaze patterns of face processing in ASD. A total of 75 articles (91 studies) and 4209 individuals (ASD: 2027; controls: 2182) across all age ranges (i.e., childhood through to adulthood) from both Eastern and Western cultures were included in this meta-analysis. Individuals with ASD yielded shorter fixation durations to the eyes than individuals without ASD. Group differences in the time spent fixating on the eyes were not modulated by age, but affected by culture. Effect size in the eastern culture was larger than that in the western culture. In contrast, group differences on time spent looking at the mouth were not significant, but changed with age and modulated by culture. Relative to the neurotypical controls, Western individuals with ASD spent more time looking at the mouth from school age, whereas Eastern individuals with ASD did not gaze longer on mouth until adulthood. These results add to the body of evidence supporting atypical gaze behaviors to eyes in ASD and provide new insights into a potential mouth compensation strategy that develops with age in ASD. LAY SUMMARY: Individuals with autism spectrum disorder (ASD) often show atypical gaze patterns when looking at others' faces compared to neurotypical individuals. This paper examines the role of age and culture on pattern of gaze abnormalities in individuals with ASD. Results show that reduction of gaze on eyes in ASD is stable across all ages and cultures, while increase of gaze on mouth emerges as individuals with ASD get older. The findings provide a developmental insight to the gaze patterns on the autism spectrum across culture.

Atypical Head Movement during Face-to-Face Interaction in Children with Autism Spectrum Disorder / Z. ZHAO in Autism Research, 14-6 (June 2021)  

Public ISBD [article]  inAutism Research > 14-6 (June 2021) . - p.1197-1208 Titre : Atypical Head Movement during Face-to-Face Interaction in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Z.

Children with autism spectrum disorder (ASD) and typical development (TD) were engaged in a structured conversation with an interlocutress while wearing an eye tracker. We computed the head movement stereotypy with multiscale entropy analysis. In addition, the head rotation range (RR) and the amount of rotation per minute (ARPM) were calculated to quantify the extent of head movement. Results demonstrated that the ASD group had significantly higher level of movement stereotypy, RR and ARPM in all the three directions of head movement. Further analyses revealed that the extent of head movement could be significantly explained by movement stereotypy, but not by the amount of visual fixation to the interlocutress. These results demonstrated the atypical head movement dynamics in children with ASD during live interaction. It is proposed that head movement might potentially provide novel objective biomarkers of ASD. LAY SUMMARY: Our study used an objective tool to quantify head movement in children with autism. Results showed that children with autism had more stereotyped and greater head movement. We suggest that head movement tracking technique be widely used in autism research.

A constellation of eye-tracking measures reveals social attention differences in ASD and the broad autism phenotype / Kritika NAYAR in Molecular Autism, 13 (2022)  

Public ISBD [article]  inMolecular Autism > 13 (2022) . - 18 p. Titre : A constellation of eye-tracking measures reveals social attention differences in ASD and the broad autism phenotype Type de document : Texte imprimé et/ou numérique Auteurs : Kritika NAYAR, Auteur ; Frederick SHIC, Auteur ; Molly WINSTON, Auteur ; Molly LOSH, Auteur Article en page(s) : 18 p. Langues : Anglais (eng) Mots-clés : Attention  Autism Spectrum Disorder/diagnosis  Autistic Disorder  Eye-Tracking Technology  Fixation, Ocular  Humans  Phenotype  Autism spectrum disorder  Broad autism phenotype  Endophenotype  Eye tracking  Social attention  Visual processing Index. décimale : PER Périodiques Résumé : BACKGROUND: Social attention differences, expressed through gaze patterns, have been documented in autism spectrum disorder (ASD), with subtle differences also reported among first-degree relatives, suggesting a shared genetic link. Findings have mostly been derived from standard eye-tracking methods (total fixation count or total fixation duration). Given the dynamics of visual attention, these standard methods may obscure subtle, yet core, differences in visual attention mechanisms, particularly those presenting sub-clinically. This study applied a constellation of eye-tracking analyses to gaze data from individuals with ASD and their parents. METHODS: This study included n=156 participants across groups, including ASD (n=24) and control (n=32) groups, and parents of individuals with ASD (n=61) and control parents (n=39). A complex scene with social/non-social elements was displayed and gaze tracked via an eye tracker. Eleven analytic methods from the following categories were analyzed: (1) standard variables, (2) temporal dynamics (e.g., gaze over time), (3) fixation patterns (e.g., perseverative or regressive fixations), (4) first fixations, and (5) distribution patterns. MANOVAs, growth curve analyses, and Chi-squared tests were applied to examine group differences. Finally, group differences were examined on component scores derived from a principal component analysis (PCA) that reduced variables to distinct dimensions. RESULTS: No group differences emerged among standard, first fixation, and distribution pattern variables. Both the ASD and ASD parent groups demonstrated on average reduced social attention over time and atypical perseverative fixations. Lower social attention factor scores derived from PCA strongly differentiated the ASD and ASD parent groups from controls, with parent findings driven by the subset of parents demonstrating the broad autism phenotype. LIMITATIONS: To generalize these findings, larger sample sizes, extended viewing contexts (e.g., dynamic stimuli), and even more eye-tracking analytical methods are needed. CONCLUSIONS: Fixations over time and perseverative fixations differentiated ASD and the ASD parent groups from controls, with the PCA most robustly capturing social attention differences. Findings highlight their methodological utility in studies of the (broad) autism spectrum to capture nuanced visual attention differences that may relate to clinical symptoms in ASD, and reflect genetic liability in clinically unaffected relatives. This proof-of-concept study may inform future studies using eye tracking across populations where social attention is impacted.

Altered interactive dynamics of gaze behavior during face-to-face interaction in autistic individuals: a dual eye-tracking study / Bastian SCHILLER ; Antonia VEHLEN ; Kathrin NICKEL ; Ludger Tebartz VAN ELST ; Gregor DOMES ; Markus HEINRICHS in Molecular Autism, 16 (2025)  

Public ISBD [article]  inMolecular Autism > 16 (2025) . - 12 Titre : Altered interactive dynamics of gaze behavior during face-to-face interaction in autistic individuals: a dual eye-tracking study Type de document : Texte imprimé et/ou numérique Auteurs : Bastian SCHILLER, Auteur ; Antonia VEHLEN, Auteur ; Kathrin NICKEL, Auteur ; Ludger Tebartz VAN ELST, Auteur ; Gregor DOMES, Auteur ; Markus HEINRICHS, Auteur Article en page(s) : 12 Langues : Anglais (eng) Mots-clés : Humans  Male  Female  Eye-Tracking Technology  Autistic Disorder/physiopathology/psychology  Fixation, Ocular  Adult  Young Adult  Social Interaction  Adolescent  Eye Movements  Case-Control Studies  Autism spectrum  Dual eye-tracking  Naturalistic gaze behavior  Social interaction  the University of Freiburg approved this study (reference number: EK-Freiburg:  439/15). All participants gave written informed consent before the experiment  took place.

Consent for publication: Not applicable. Competing interests:  The authors declare no competing interests. Index. décimale : PER Périodiques Résumé : BACKGROUND: Previous eye-tracking research on autistic individuals has mostly examined the gaze behavior of one individual in response to social stimuli presented on a computer screen, suggesting that there is atypical gaze behavior. However, it is unknown how these findings translate to the interactive dynamics of gaze behavior during "face-to-face" encounters between two individuals. Only by analyzing the gaze behaviour of both interaction partners is it possible to determine the frequency of actual eye-contact and who initiates or breaks such periods of mutual eye gaze. The knowledge gained from this analysis could contribute to theorizing about the psychological mechanisms (e.g., gaze avoidance vs. gaze indifference) underlying autism. METHODS: The present study applied a novel dual eye-tracking setup that allows the assessment and analysis of the interactive dynamics of gaze behavior regarding (i) mutual eye gaze (i.e., eye contact), (ii) initiations, and (iii) break-ups of eye contact. Participants (37 autistic individuals, 37 age- and IQ-matched neurotypical individuals) performed a semi-standardized social interaction (i.e., Fast Friends Procedure) with a confederate (trained to interact in a standardized manner). RESULTS: Eye contact was reduced in interactions involving autistic individuals. Additional analyses revealed that this reduction was primarily due to the more frequent breaking of eye contact by these individuals. We also found considerable heterogeneity among autistic individuals, with atypical gaze behavior present in only about half of the sample. LIMITATIONS: Further research is required to determine whether the interactive dynamics of gaze behavior observed in this dual eye-tracking setup can be generalized to real-world situations. Future studies could also include arousal-related physiological measures. CONCLUSIONS: By tracking the gaze behavior of two interacting individuals, this study reveals specific atypicalities in the interactive dynamics of gaze behavior in a subset of autistic individuals, potentially informing diagnostic and therapeutic decisions. More broadly, our study highlights the added value of dual eye-tracking in elucidating the interactive nature of social encounters in both neurodiverse and neurotypical individuals. TRIAL REGISTRATION: The study was registered as a clinical trial before starting data collection ( https://drks.de/search/en/trial/DRKS00018957 ; Registration Date: 12/17/2019).
