during various types of stress, are linked to attenuated stress responding and positive health …

Polyvagal theory suggests that parasympathetic regulation of cardiac function, indexed by
resting respiratory sinus arrhythmia (RSA), may be a marker of emotion regulatory capacity …

BACKGROUND: The stimulation-seeking theory posits that individuals with low habitual
autonomic arousal levels will seek stimulation to increase their arousal to more optimal …

Bullying and peer victimization are stressful experiences for youth, and are associated with
