Dynamic regulatory processes among child welfare parents: Temporal associations between physiology and parenting behavior / Xutong ZHANG in Development and Psychopathology, 36-4 (October 2024)  

Public ISBD [article]  inDevelopment and Psychopathology > 36-4 (October 2024) . - p.1653-1668 Titre : Dynamic regulatory processes among child welfare parents: Temporal associations between physiology and parenting behavior Type de document : Texte imprimé et/ou numérique Auteurs : Xutong ZHANG, Auteur ; Lisa M.

Time-series data of cardiac indices (second-by-second estimates of inter-beat intervals - IBI, and respiratory sinus arrhythmia - RSA) and parenting behaviors were obtained from 204 child welfare-involved parents (88% mothers, Mage = 32.32 years) during child-led play with their 3- to 7-year-old children (45.1% female; Mage = 4.76 years). Known risk factors for maltreatment, including parents' negative social cognitions, mental health symptoms, and inhibitory control problems, were examined as moderators of intra-individual physiology-behavior associations. Results of ordinary differential equations suggested increases in parents' cardiac arousal at moments when they showed positive parenting behaviors. In turn, higher arousal was associated with momentary decreases in both positive and negative parenting behaviors. Individual differences in these dynamic processes were identified in association with parental risk factors. In contrast, no sample-wide RSA-behavior associations were evident, but a pattern of increased positive parenting at moments of parasympathetic withdrawal emerged among parents showing more total positive parenting behaviors. This study illustrated an innovative and ecologically-valid approach to examining regulatory patterns that may shape parenting in real-time and identified mechanisms that should be addressed in interventions.

Associations between physiological and neural measures of sensory reactivity in youth with autism / J. JUNG in Journal of Child Psychology and Psychiatry, 62-10 (October 2021)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-10 (October 2021) . - p.1183-1194 Titre : Associations between physiological and neural measures of sensory reactivity in youth with autism Type de document : Texte imprimé et/ou numérique Auteurs : J.

While individuals with ASD often show atypically high physiological arousal, it is unclear how this relates to sensory reactivity. We therefore investigated how physiological arousal relates to brain and behavioral indices of SOR, to inform understanding of the biological mechanisms underlying SOR and to determine whether physiological measures are associated with SOR-related brain responses. METHODS: Youth aged 8-18 (49 ASD; 30 age- and performance-IQ-matched typically developing (TD)) experienced mildly aversive tactile and auditory stimuli first during functional magnetic resonance imaging (N = 41 ASD, 26 TD) and then during skin conductance (SCR) (N = 48 ASD, 28 TD) and heart rate (HR) measurements (N = 48 ASD, 30 TD). Parents reported on their children's SOR severity. RESULTS: Autism Spectrum Disorder youth overall displayed greater SCR to aversive sensory stimulation than TD youth and greater baseline HR. Within ASD, higher SOR was associated with higher mean HR across all stimuli after controlling for baseline HR. Furthermore, the ASD group overall, and the ASD-high-SOR group in particular, showed reduced HR deceleration/greater acceleration to sensory stimulation compared to the TD group. Both SCR and HR were associated with brain responses to sensory stimulation in regions previously associated with SOR and sensory regulation. CONCLUSIONS: Autism Spectrum Disorder youth displayed heightened physiological arousal to mildly aversive sensory stimulation, with HR responses in particular showing associations with brain and behavioral measures of SOR. These results have implications for using psychophysiological measures to assess SOR, particularly in individuals with ASD who cannot undergo MRI.

Behavioral and physiological differences during an emotion-evoking task in children at increased likelihood for autism spectrum disorder / Lori-Ann R. SACREY in Development and Psychopathology, 36-1 (February 2024)  

Public ISBD [article]  inDevelopment and Psychopathology > 36-1 (February 2024) . - p.404-414 Titre : Behavioral and physiological differences during an emotion-evoking task in children at increased likelihood for autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Lori-Ann R.

We examined behavioral and physiological responses during an emotion-evoking task designed to elicit emotional states in infants. Infants at an increased likelihood for ASD (IL; have an older sibling with ASD; 96 not classified; 29 classified with ASD at age two) and low likelihood (LL; no family history of ASD; n = 61) completed the task at 6, 12, and 18 months. The main findings were (1) the IL-ASD group displayed higher levels of negative affect during toy removal and negative tasks compared to the IL non-ASD and LL groups, respectively, (2) the IL-ASD group spent more time looking at the baseline task compared to the other two groups, and (3) the IL-ASD group showed a greater increase in heart rate from baseline during the toy removal and negative tasks compared to the LL group. These results suggest that IL children who are classified as ASD at 24 months show differences in affect, gaze, and heart rate during an emotion-evoking task, with potential implications for understanding mechanisms related to emerging ASD.

Specificity of autonomic arousal to anxiety in children with autism spectrum disorder / Tabitha A. CHIU in Autism Research, 9-4 (April 2016)

Current assessment and treatment of anxiety, which rely on the observation of behavior and self-reports, are often ineffective as ASD is associated with deficits in communication and diminished introspective ability. In this light, autonomic nervous system (ANS) activity has been suggested as a marker of physiological arousal associated with anxiety. However, physiological arousal measured by ANS indices also occurs with other cognitive and emotional processes, and it is unclear whether anxiety-related arousal can be differentiated from that related to other cognitive processes. To address this gap, we investigated the use of linear and nonlinear classification techniques for differentiating anxiety-related arousal from arousal due to three cognitive processes (attention, inhibitory control, and social cognition) and physical activity based on electrocardiography signal features. Our results indicate that over 80% classification accuracy can be achieved, suggesting that ANS response can be used as a specific marker of anxiety-related arousal in a subgroup of children with ASD who demonstrate an increase in heart rate in response to anxiogenic stimuli.

The neurobiological presentation of anxiety in autism spectrum disorder: A systematic review / A. J. MCVEY in Autism Research, 12-3 (March 2019)  

Public ISBD [article]  inAutism Research > 12-3 (March 2019) . - p.346-369 Titre : The neurobiological presentation of anxiety in autism spectrum disorder: A systematic review Type de document : Texte imprimé et/ou numérique Auteurs : A. J. MCVEY, Auteur Article en page(s) : p.346-369 Langues : Anglais (eng) Mots-clés : anxiety  autism spectrum disorder  neurophysiology  physiology Index. décimale : PER Périodiques Résumé : Anxiety is common among people with autism and is associated with unique and additive challenges. Anxiety is thought to have neurobiological components, and measures of arousal in typical development have long been studied. Recently, neurobiological measures of anxiety in autism have begun to receive empirical evaluation, but results have not yet been examined together. This systematic review, therefore, summarizes the state of the research of the neurobiology of anxiety in autism. Studies published between 1999 and June 2017 were reviewed. Results across measures of arousal point to inconsistencies in results and a lack of synthesis in the literature. Considerations regarding these inconsistencies are discussed, recommendations for future studies are offered, and clinical implications for this work are presented. Autism Res 2019, 12: 346-369 (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Anxiety is common among people with autism. Because anxiety has been linked with a variety of differences in physiological (bodily) and neurophysiological (brain) functioning in people without autism, research has begun to examine these processes in autism as well. This literature, however, has not yet been examined as a whole. Therefore, this paper begins to address that gap to provide the field with a better understanding of how anxiety affects people with autism and discusses implications for future research and clinical practice.
