Does rejecting negative emotions impact your heart rate?

What does vagus-mediated heart rate variability (vmHRV) indicate in terms of physiological activity?

It is a peripheral measure of parasympathetic nervous system (PNS) activity and prefrontal inhibition of the amygdala, reflecting emotion regulation capacity.

What does high resting heart rate variability (HRV) typically indicate about the autonomic nervous system?

High resting HRV indicates a flexible parasympathetic nervous system (PNS) capable of adjusting to environmental demands, while low HRV indicates a dominant, inflexible sympathetic influence.

What primary time-domain HRV metric was used in the main analyses, and why was it chosen?

The Root Mean Square of Successive Differences (RMSSD) was used because it is mediated by the vagus nerve and directly indicates parasympathetic nervous system activity.

How did this study's subscale findings differ from Williams et al. (2015), and why might this discrepancy exist?

Williams et al. found impulse control and clarity associated with resting HRV, whereas this study found non-acceptance; this may be because Williams et al. controlled for anxiety and rumination, which could strip away valid emotion regulation variance.

According to the authors, why does non-acceptance of negative emotions associate strongly with lower vmHRV?

Non-acceptance/suppression acts as an inflexible strategy that increases cognitive load and physiological arousal, indicating limited prefrontal cortical inhibition over the amygdala.
