FeaturedNeurosciencePsychology·November 18, 2024·3 min readStudy Debunks Heart Rate Variability as Predictor of AggressionNew research has found no evidence linking heart rate variability (HRV) to reactive aggression, overturning previous theories. HRV measures the variation between heartbeats and has been associated with stress resilience, but this study shows it is not a reliable biomarker for aggression.Read More

This synchronization depends on physiological responses rather than mood or music preferences. The findings help explain the collective emotional experiences of audiences and suggest ways to enhance theater performances. The research offers valuable clues for improving the performing arts.Read More
