Higher resting heart rate variability predicts skill in expressing some emotions

Area of Science:

• Psychophysiology
• Neuroscience
• Emotion Science

Background:

• Vagally mediated heart rate variability (vmHRV) quantifies cardiac vagal tone.
• vmHRV is considered a key indicator of emotional regulation capacity.
• Previous research has not directly examined the relationship between vmHRV and facial emotion expression abilities.

Purpose of the Study:

• To investigate the association between resting vmHRV and objectively assessed facial emotion expression.
• To test the hypothesis that higher vmHRV predicts enhanced facial expressive skills.

Main Methods:

• Eighty healthy women participated in the study.
• Participants completed self-report measures and underwent laboratory assessments.
• vmHRV and the ability to facially express six emotions were objectively evaluated.

Main Results:

• A marginal main effect of vmHRV on overall expressive skill was observed.
• Individuals with higher resting vmHRV demonstrated superior ability to deliberately express anger and interest facially.
• No significant associations were found for other emotions.

Conclusions:

• Resting vmHRV is associated with the capacity for facial expression of specific emotions, namely anger and interest.
• These findings suggest vmHRV's role in modulating distinct emotional expression channels.
• The results have potential implications for understanding health and well-being through the lens of emotion regulation and expression.
