Investigating the relationship between emotional granularity and cardiorespiratory physiological activity in daily life

In this project, we test the hypothesis that emotional granularity (a measure of the precision of an individual’s emotion concepts) is significantly positively correlated with resting respiratory sinus arrhythmia (RSA; used as an index of parasympathetic activity and proxy measure of efficient allostasis) as measured in daily life. We further investigate the nature of this relationship by characterizing patterns of cardiorespiratory activity during resting periods and emotional events, including and in comparison with measures of emotional granularity.
