Cardiac perception enhances stress experience.

In the present study we aimed to investigate the impact of the ability to perceive bodily changes as indexed by the perception of one’s heartbeat (cardiac perception) on emotional experience when being confronted with a mental stressor. To induce stress, participants high and low in cardiac perception performed a computerized mental arithmetic test while listening to a white noise increasing in volume. Emotional experience and heart rate were assessed as indices of stress response. Our results show that participants high in cardiac perception reported more negative emotions during the stress period compared to participants low in cardiac perception, though heart rate did not differ between the groups. Our findings suggest that cardiac perception moderates the stress experience by enhancing the perceived emotion. Thus we were able to demonstrate that cardiac perception contributes as a factor explaining the variance in individuals’ emotional response to a stressor.
