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.

Behavior analytic interventions for children with autism: Policy and practice in the United Kingdom and China / Y. LIAO in Autism, 26-1 (January 2022)  

Public ISBD [article]  inAutism > 26-1 (January 2022) . - p.101-120 Titre : Behavior analytic interventions for children with autism: Policy and practice in the United Kingdom and China Type de document : Texte imprimé et/ou numérique Auteurs : Y.

HU, Auteur Article en page(s) : p.101-120 Langues : Anglais (eng) Mots-clés : China  United Kingdom  applied behavior analysis  autism spectrum disorders  policy Index. décimale : PER Périodiques Résumé : The prevalence of autism is increasing, and the development of these children and the lived experience of their families have become a global concern. Applied behavioral analytic intervention is proved to be effective in improving their cognitive abilities, language skills, and social and emotional skills, but the service delivery between developed and developing countries is different. A qualitative study was conducted to explore personal experiences with actual practice fidelity of behavior analytic services for children with autism in a Western developed country (United Kingdom) and an Eastern developing country (China). The study found: (1) a lack of support for autism and behavioral analytic services in both countries; (2) applied behavioral analytic intervention was not as widely endorsed by healthcare or educational systems in the United Kingdom; Chinese parents faced challenges around inclusive education and accessing high-quality services and there was a social stigma attached to autism; (3) a limited awareness and application of early intensive behavior intervention in both regions; and (4) intervention fidelity with regards to the practice of one particular aspect of behavioral analytic interventions was similar and increased with ongoing training. This study emphasizes the need to support children with autism, and to consider regional adaptations of evidence-based practice of behavior analytic interventions for the affected population.

Brief Report: Using Computer-Assisted Multiple Exemplar Instruction to Facilitate the Development of Bidirectional Naming for Children with Autism Spectrum Disorder / G. T. LEE in Journal of Autism and Developmental Disorders, 51-12 (December 2021)

Many children with autism spectrum disorder (ASD) or developmental delays do not demonstrate this ability and require systematic instruction. The purpose of the present study was to evaluate the efficacy of computer-assisted multiple exemplar instruction to facilitate bidirectional naming. Three 5-year-old Chinese boys with ASD participated in a multiple probe across three participants design. The results indicated that all three children's naming performance increased from pretest to posttest, supporting the potential practicality of the instructional system for use in applied settings.

As a novelty, this study aimed to quantify the complex movements produced during social interactions in order to test differences in ASD movement dynamics and their convergence, or lack thereof, during social interactions. Twenty children with ASD and twenty-three children with typical development (TD) were videotaped while engaged in a face-to-face conversation with an interviewer. An image differencing technique was utilized to extract the movement time series. Spectral analyses were conducted to quantify the average power of movement, and the fractal scaling of movement. The degree of complexity matching was calculated to capture the level of behavioral coordination between the interviewer and children.

The Mediating Role of Parenting Stress in the Relations Between Parental Emotion Regulation and Parenting Behaviors in Chinese Families of Children with Autism Spectrum Disorders: A Dyadic Analysis / X. HU in Journal of Autism and Developmental Disorders, 49-10 (October 2019)

This study used an actor-partner interdependence mediation (APIMeM) model to investigate the intrapersonal and interpersonal effects of emotion dysregulation and parenting stress on parenting behaviors among 211 pairs (total N = 422) of Chinese parents of children with ASD. The results indicated that for both fathers and mothers, there were significant indirect actor effects of parental emotion dysregulation on parents' own parenting behaviors through their own parenting stress. However, no significant direct or indirect partner effect was found in the analyses. These findings suggest that the emotional parenting dynamics occurred on the individual rather than the dyadic level in these families.
