Atypical Head Movement during Face-to-Face Interaction in Children with Autism Spectrum Disorder / Z. ZHAO in Autism Research, 14-6 (June 2021)
[article]
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. ZHAO, Auteur ; Z. ZHU, Auteur ; X. ZHANG, Auteur ; H. TANG, Auteur ; J. XING, Auteur ; X. HU, Auteur ; J. LU, Auteur ; Q. PENG, Auteur ; X. QU, Auteur Article en page(s) : p.1197-1208 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Autistic Disorder Child Fixation, Ocular Head Movements Humans Stereotyped Behavior autism biomarker eye tracking head movement stereotypy Index. décimale : PER Périodiques Résumé : The present study implemented an objective head pose tracking technique-OpenFace 2.0 to quantify the three dimensional head movement. 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.

Titre : Identifying Autism with Head Movement Features by Implementing Machine Learning Algorithms Type de document : Texte imprimé et/ou numérique Auteurs : Zhong ZHAO, Auteur ; Zhipeng ZHU, Auteur ; Xiaobin ZHANG, Auteur ; Haiming TANG, Auteur ; Jiayi XING, Auteur ; Xinyao HU, Auteur ; Jianping LU, Auteur ; Xingda QU, Auteur Article en page(s) : p.3038-3049 Langues : Anglais (eng) Mots-clés : Algorithms Autism Spectrum Disorder/diagnosis Autistic Disorder Child Head Movements Humans Machine Learning Autism Biomarkers Diagnosis Head movement Index. décimale : PER Périodiques Résumé : Our study investigated the feasibility of using head movement features to identify individuals with autism spectrum disorder (ASD). Children with ASD and typical development (TD) were required to answer ten yes-no questions, and they were encouraged to nod/shake head while doing so. The head rotation range (RR) and the amount of rotation per minute (ARPM) in the pitch (head nodding direction), yaw (head shaking direction) and roll (lateral head inclination) directions were computed, and further fed into machine learning classifiers as the input features. The maximum classification accuracy of 92.11% was achieved with the decision tree classifier with two features (i.e., RR_Pitch and ARPM_Yaw). Our study suggests that head movement dynamics contain objective biomarkers that could identify ASD.

NYSTROM, Auteur ; G. GREDEBACK, Auteur ; Sven BÖLTE, Auteur ; T. FALCK-YTTER, Auteur Article en page(s) : 12p. Langues : Anglais (eng) Mots-clés : Attention/physiology Autism Spectrum Disorder/diagnosis/epidemiology/physiopathology Cues Early Diagnosis Eye Movements Family Health Female Fixation, Ocular/physiology Head Movements Humans Imitative Behavior/physiology Infant Male Pursuit, Smooth/physiology Risk Single-Blind Method Social Behavior Social Perception Autism Communication Early development Gaze following Joint attention Neurodevelopmental disorders Social cognition Younger siblings Index. décimale : PER Périodiques Résumé : BACKGROUND: The ability to follow gaze is an important prerequisite for joint attention, which is often compromised in children with autism spectrum disorder (ASD). The direction of both the head and eyes provides cues to other people's attention direction, but previous studies have not separated these factors and their relation to ASD susceptibility. Development of gaze following typically occurs before ASD diagnosis is possible, and studies of high-risk populations are therefore important. METHODS: Eye tracking was used to assess gaze following during interaction in a group of 10-month-old infants at high familial risk for ASD (high-risk group) as well as a group of infants with no family history of ASD (low-risk group). The infants watched an experimenter gaze at objects in the periphery. Performance was compared across two conditions: one in which the experimenter moved both the eyes and head toward the objects (Eyes and Head condition) and one that involved movement of the eyes only (Eyes Only condition). RESULTS: A group by condition interaction effect was found. Specifically, whereas gaze following accuracy was comparable across the two conditions in the low-risk group, infants in the high-risk group were more likely to follow gaze in the Eyes and Head condition than in the Eyes Only condition. CONCLUSIONS: In an ecologically valid social situation, responses to basic non-verbal orienting cues were found to be altered in infants at risk for ASD. The results indicate that infants at risk for ASD may rely disproportionally on information from the head when following gaze and point to the importance of separating information from the eyes and the head when studying social perception in ASD.
