Brief Report: Evidence for Normative Resting-State Physiology in Autism / Heather J. NUSKE in Journal of Autism and Developmental Disorders, 44-8 (August 2014)

NUSKE, Auteur ; Giacomo VIVANTI, Auteur ; Cheryl DISSANAYAKE, Auteur Article en page(s) : p.2057-2063 Langues : Anglais (eng) Mots-clés : Resting-state physiology  Autism  Pupillometry  Baseline  Eye-tracking  Autonomic nervous system Index. décimale : PER Périodiques Résumé : Although the conception of autism as a disorder of abnormal resting-state physiology has a long history, the evidence remains mixed. Using state-of-the-art eye-tracking pupillometry, resting-state (tonic) pupil size was measured in children with and without autism. No group differences in tonic pupil size were found, and tonic pupil size was not related to age or cognitive ability in either group, and nor was it related to autistic symptoms. We suggest that previous findings of hyper-arousal in autism at baseline may be a product of different recording methods, in particular different movement-artifact removal techniques. These results question the notion that autism is associated with a fundamental dysregulation in resting-state physiology. Further research, employing such techniques is needed to confirm these findings.

Developmental delays in emotion regulation strategies in preschoolers with autism / Heather J. NUSKE in Autism Research, 10-11 (November 2017)  

Public ISBD [article]  inAutism Research > 10-11 (November 2017) . - p.1808-1822 Titre : Developmental delays in emotion regulation strategies in preschoolers with autism Type de document : Texte imprimé et/ou numérique Auteurs : Heather J. NUSKE, Auteur ; Darren HEDLEY, Auteur ; Alexandra WOOLLACOTT, Auteur ; Phoebe THOMSON, Auteur ; Suzanne MACARI, Auteur ; Cheryl DISSANAYAKE, Auteur Article en page(s) : p.1808-1822 Langues : Anglais (eng) Mots-clés : emotion regulation strategies  autism  mental health  wellbeing  self-development  preschool  independence  child emotional wellbeing scale Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorder (ASD) commonly present with difficulty regulating negative emotions, which has been found to impact their behavioral and mental health. Little research has documented the strategies that children with ASD use to regulate their emotion to understand whether they use qualitatively different strategies to children without ASD, whether these are developmentally delayed, or both. Forty-four children with ASD and 29 typically-developing children (2–4 years) were given tasks designed to mimic everyday life experiences requiring children to manage low-level stress (e.g., waiting for a snack) and children's emotion regulation strategies were coded. Parents reported on their child's mental health, wellbeing, and self-development. The results suggest differences in using emotion regulation strategies in children with ASD, reflecting a delay, rather than a deviance when compared to those used by children without ASD. Only children with ASD relied on their family members for physical and communicative soothing; the typically developing children relied on people outside of their family for help regulating their emotion. More frequent approach/less frequent avoidance was related to a higher self-evaluation in both groups, but was only additionally related to higher self-recognition and autonomy in the ASD group. These findings help to identify important emotion regulation intervention targets for this population, including supporting communication with people outside of the family and independence. Autism Res 2017, 10: 1808–1822. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary Results suggest that children with autism had more difficulty using communication strategies to manage stress only with people outside the family; they used these strategies with family members as often as children without autism. For all children, more task approach/less avoidance was related to children's higher self-evaluation. These findings suggest targeting communication with people outside of the family and personality development as appropriate intervention goals.

No Evidence of Emotional Dysregulation or Aversion to Mutual Gaze in Preschoolers with Autism Spectrum Disorder: An Eye-Tracking Pupillometry Study / Heather J. NUSKE in Journal of Autism and Developmental Disorders, 45-11 (November 2015)

To test this hypothesis we showed mutual and averted gaze stimuli to 23 mixed-ability preschoolers with ASD (M Mullen DQ = 68) and 21 typically-developing preschoolers, aged 2–5 years, using eye-tracking technology to measure visual attention and emotional arousal (i.e., pupil dilation). There were no group differences in attention to the eye region or pupil dilation. Both groups dilated their pupils more to mutual compared to averted gaze. More internalizing symptoms in the children with ASD related to less emotional arousal to mutual gaze. The pattern of results suggests that preschoolers with ASD are not dysregulated in their responses to mutual gaze.

Temperament predicts challenging behavior in children with autism spectrum disorder at age 5 / Siobhan KORBUT in Research in Autism Spectrum Disorders, 71 (March 2020)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 71 (March 2020) . - p.101492 Titre : Temperament predicts challenging behavior in children with autism spectrum disorder at age 5 Type de document : Texte imprimé et/ou numérique Auteurs : Siobhan KORBUT, Auteur ; Darren HEDLEY, Auteur ; Lacey CHETCUTI, Auteur ; Ensu SAHIN, Auteur ; Heather J. NUSKE, Auteur Article en page(s) : p.101492 Langues : Anglais (eng) Mots-clés : Autism  ASD  Challenging behavior  Developmental delay  Temperament Index. décimale : PER Périodiques Résumé : Background Challenging behaviors during early childhood have a significant impact on cognitive and social development. The present study aimed to identify the developmental predictors of these behaviors in preschool aged children with Autism Spectrum Disorder (ASD) at 2-year follow-up. We examined temperament, which has been identified as key to emotion regulation in typical development, as well as developmental level and ASD symptom severity, as potential predictors of parent-reported challenging behavior. Method Forty-three parents of preschool aged children with ASD from a previous study were invited to participate. Data from 26 children with ASD aged 4–6 years (M = 5, SD = .60) were available for follow-up analyses. Developmental level, ASD symptom severity, and temperamental difficulty at baseline were considered as potential predictors of frequency and severity of challenging behavior at follow-up. Results Baseline negative affectivity was uniquely predictive of frequency of challenging behavior at follow-up. Although no individual variable was identified as a unique predictor of variance, the combined effects of temperament were predictive of the severity of challenging behavior at follow-up, contributing to 46 % of variance in scores. Conclusions These findings highlight the potential impact of emotion-regulation related aspects of temperament on later emerging challenging behavior in young children with ASD, suggesting opportunities for early intervention. Results also identified a role for developmental level in the severity of challenging behavior, but suggest that the effect may be metered by temperament.
