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.
