Do Decision-Making Styles Predict Vagal Control? The Role of Resting Heart Rate Variability

Area of Science:

• Psychology
• Cardiology
• Biomarkers

Background:

• Decision-making styles influence behavior and mental health.
• High heart rate variability (HRV) is an indicator of health and emotional control.
• The link between decision-making styles and HRV requires further investigation.

Purpose of the Study:

• To investigate the predictive capability of decision-making styles on resting heart rate variability (HRV).
• To explore potential mechanisms linking cognitive styles to physiological health markers.

Main Methods:

• Cross-sectional study with 199 university students.
• Resting electrocardiogram (ECG) to measure frequency domain HRV variables.
• General Decision-Making Style (GDMS) questionnaire administration.

Main Results:

• The intuitive decision-making style positively predicted high-frequency HRV.
• The avoidant decision-making style negatively predicted low-frequency HRV.
• Findings suggest a cardioprotective effect of intuitive styles and a potential health risk associated with avoidant styles.

Conclusions:

• Decision-making styles are associated with physiological markers of health.
• Intuitive styles may confer a cardioprotective benefit.
• HRV could serve as a biomarker for cognitive styles impacting health.
