Blood oxytocin concentration positively predicts contagious yawning behavior in children with autism spectrum disorder / M. G. MARISCAL in Autism Research, 12-8 (August 2019)

Titre : Blood oxytocin concentration positively predicts contagious yawning behavior in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : M. G. MARISCAL, Auteur ; O. OZTAN, Auteur ; S. M. ROSE, Auteur ; R. A. LIBOVE, Auteur ; L. P. JACKSON, Auteur ; R. D. SUMIYOSHI, Auteur ; T. H. TRUJILLO, Auteur ; D. S. CARSON, Auteur ; J. M. PHILLIPS, Auteur ; J. P. GARNER, Auteur ; A. Y. HARDAN, Auteur ; Karen J. PARKER, Auteur Article en page(s) : p.1156-1161 Langues : Anglais (eng) Mots-clés : autism contagion empathy oxytocin social functioning yawning Index. décimale : PER Périodiques Résumé : Research suggests that children with autism spectrum disorder (ASD) may have reduced empathy, as measured by an impaired contagious yawn response, compared to typically developing (TD) children. Other research has failed to replicate this finding, instead attributing this phenomenon to group differences in attention paid to yawn stimuli. A third possibility is that only a subgroup of children with ASD exhibits the impaired contagious yawn response, and that it can be identified biologically. Here we quantified blood concentrations of the "social" neuropeptide oxytocin (OXT) and evaluated yawning behavior and attention rates during a laboratory task in children with ASD (N = 34) and TD children (N = 30) aged 6-12 years. No group difference in contagious yawning behavior was found. However, a blood OXT concentration x group (ASD vs. TD) interaction positively predicted contagious yawning behavior (F1,50 = 7.4987; P = 0.0085). Specifically, blood OXT concentration was positively related to contagious yawning behavior in children with ASD, but not in TD children. This finding was not due to delayed perception of yawn stimuli and was observed whether attention paid to test stimuli and clinical symptom severity were included in the analysis or not. These findings suggest that only a biologically defined subset of children with ASD exhibits reduced empathy, as measured by the impaired contagious yawn response, and that prior conflicting reports of this behavioral phenomenon may be attributable, at least in part, to variable mean OXT concentrations across different ASD study cohorts. Autism Res 2019, 12: 1156-1161. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: People with autism may contagiously yawn (i.e., yawn in response to another's yawn) less often than people without autism. We find that people with autism who have lower levels of blood oxytocin (OXT), a hormone involved in social behavior and empathy, show decreased contagious yawning, but those who have higher blood OXT levels do not differ in contagious yawning from controls. This suggests that decreased contagious yawning may only occur in a biologically defined subset of people with autism.

Titre : Brief Report: Does Eye Contact Induce Contagious Yawning in Children with Autism Spectrum Disorder? Type de document : Texte imprimé et/ou numérique Auteurs : Atsushi SENJU, Auteur ; Yoshikuni TOJO, Auteur ; Yukiko KIKUCHI, Auteur ; Hironori AKECHI, Auteur ; Toshikazu HASEGAWA, Auteur ; Hiroo OSANAI, Auteur Année de publication : 2009 Article en page(s) : p.1598-1602 Langues : Anglais (eng) Mots-clés : Yawning Contagious yawning Autism spectrum disorder Empathy Eye-fixation Gaze Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) reportedly fail to show contagious yawning, but the mechanism underlying the lack of contagious yawning is still unclear. The current study examined whether instructed fixation on the eyes modulates contagious yawning in ASD. Thirty-one children with ASD, as well as 31 age-matched typically developing (TD) children, observed video clips of either yawning or control mouth movements. Participants were instructed to fixate to the eyes of the face stimuli. Following instructed fixation on the eyes, both TD children and children with ASD yawned equally frequently in response to yawning stimuli. Current results suggest that contagious yawning could occur in ASD under an experimental condition in which they are instructed to fixate on the yawning eyes.
