BioResonant interfaces : tangible, subliminal biofeedback to regulate physiological states
… mindful daily life. Based on the principle of respiratory sinus arrhythmia (RSA) and physiological synchronization, the BioResonant interface is designed to stimulate at the subconscious level using subliminal tactile biofeedback. Through this process, the user's physiological state can be …

Resting Microvascular and Autonomic Function in Relation to Age and Sex Hormone Concentrations
… and MFI. Aging negatively correlated with respiratory sinus arrhythmia (RSA) indicating lower parasympathetic activity and positively correlated with diastolic blood pressure (DBP) and mean arterial pressure (MAP). Estradiol positively correlated with the low frequency/high frequency ratio …

Vagal tone and depression in adolescents: Protective factors during parent-adolescent interaction
… the role that vagal tone, as measured by respiratory sinus arrhythmia (RSA) at rest and during emotionally relevant stressors, plays in adolescent symptoms of depression. Mothers and their adolescents (ages 11-17) participated as dyads (N = 58) in paced-breathing and real-time family …

Proactive and Reactive Aggression, Respiratory Sinus Arrhythmia, and Sleep in Adolescents
… aimed to explore this further, investigating if respiratory sinus arrhythmia (RSA), a biomarker for emotion regulation and parasympathetic-mediated cardiac activity, was mediating the relationship between sleep and aggression among a sample of adolescents. The results of the study revealed that …

Early Parasympathetic Activity Predicts Later Childhood Social Functioning as Mediated by Emotion Regulation
… engagement indicate that resting and reactive respiratory sinus arrhythmia (RSA), which reflect vagal activity, in early childhood can inform the development of social and emotional behaviors later in life. Low RSA at baseline and during a stressful task have been associated with symptoms of ED …

Respiratory Sinus Arrhythmia and Restricted Repetitive Behaviors in Autism Spectrum Disorder
… theories as mutually exclusive. This study used respiratory sinus arrhythmia (RSA) patterns in children with and without an ASD diagnosis as an indicator of ANS functioning to analyze its relationship to the manifestation of RRBs. Baseline RSA and RSA reactivity were found to predict RRB severity …

Defensive Neurophysiological Response: Exploring the Neural and Autonoic Correlates of Social Behavior
… (i.e., insula, amygdala) and autonomic (i.e., respiratory sinus arrhythmia; RSA) markers of language, social, and behavioral challenges in autism spectrum disorders (ASD; Bal et al., 2010; DiMartino, Ross, et al., 2009; Lorenzi, Patriquin, & Scarpa, 2011; Patriquin, Scarpa, Friedman, & Porges, …

Do Less Consistent Night-To-Night Sleep Patterns Impact Emotional Processing Among Healthy School-Aged Children?
… after two nights of partial sleep restriction. Respiratory sinus arrhythmia (RSA) was assessed as an objective measure of emotional regulation during one task. Contrary to expectations, sleep IIV was unassociated with parent and child reported anxiety and internalizing symptoms, as well as …

Interactive contributions of children’s negative or positive behavior and maternal cardiac physiology to parenting in real time: An integration of biology and context
… for each 15-sec interval of the puzzle task via Respiratory Sinus Arrhythmia (RSA). Results from multilevel models showed that when children displayed increases in negative emotions and behaviors in a given 15-sec interval of the task, mothers who displayed vagal augmentation (an index of social …

Parenting and internalizing symptoms in early adolescence: The moderating role of vagal tone
The present study investigated baseline respiratory sinus arrhythmia (RSA) as moderator of the prospective association between parenting and internalizing symptoms among a group of typically developing adolescents across the transition to middle school. At Time 1 (5th grade; spring before middle …

Parenting Self-Efficacy and Dyadic Autonomic Responses During Parent-Child Conflict
… and autonomic self-regulation, using respiratory sinus arrhythmia (RSA) as a dynamic and sensitive indicator of physiological affective regulation during parent-adolescent conflict. Grounded in social cognitive theory, I examined how parenting self-efficacy relates to parents’ …

Real-time mother-child physiological coordination: the moderating effect of a mutually responsive orientation
… and child parasympathetic dynamics (i.e., Respiratory Sinus Arrhythmia; RSA) and dyadic behaviors in 15-s epochs to test the extent to which physiological coordination within the dyad was contingent on the dyad’s mutually responsive orientation (MRO; assessed via observer ratings). Based on …

Early neighborhood disadvantage and risk for internalizing problems: underlying neurobiological mechanisms
… coefficient in the DMN and greater resting respiratory sinus arrhythmia (RSA) at a trend level. Greater early exposure to average PM2.5 levels was associated with reduced global efficiency in the DMN. Greater number of days with exposure to high PM2.5 levels was associated with reduced …

Coping with social stress in early adolescence: The interactive contribution of observed emotional climate and youth physiology
… PNS functioning was assessed via baseline respiratory sinus arrhythmia (RSA) collected during a resting task. Youths’ self-reported engaged coping and social advice-seeking (from parents) behaviors were collected at both waves of data collection. Results suggest that during mother-youth …

Examining the neurovisceral integration model through fNIRS
… of the CAN is shown to be associated with respiratory sinus arrhythmia (RSA), as the vagus nerve is part of this feedback system. While the NVM has been examined through neural imaging and RSA, only a few studies have examined these measures simultaneously during the neuroimaging procedure. …

THE EFFECT OF ENGAGEMENT IN COGNITIVE REAPPRAISAL IN RESPONSE TO PREVIOUSLY CONDITIONED STIMULI ON ONLINE AND LONG-TERM EXPECTANCY RATINGS AND EMOTION INDICES
… between cardiac vagal control, indexed by respiratory sinus arrhythmia (RSA), and subsequent sympathetic arousal during fear conditioning, indexed by SCR. Results demonstrate that participants with low, compared to high, resting RSA had larger SCRs during habituation and conditioning …

Autonomic Nervous System Correlates of Emotion Regulation in Autistic Adults
… study examined ANS activity, as measured by respiratory sinus arrhythmia (RSA), root mean square successive differences (rMSSD), and skin conductance level (SCL), and subjective ratings of valence and arousal at rest and while viewing emotional film clips and engaging in emotion regulation in …

The Role of Cardiac Vagal Tone in Prediction of Individual Differences in Attention and Emotion Processing After Sleep Restriction
… examined. The role of vagal tone, indexed by Respiratory Sinus Arrhythmia (RSA), was examined as a trait-like individual difference variable for prediction of vulnerability to sleep loss. Healthy, good sleepers between the ages of 17-30 were recruited from a university population for …
