| Research Abstract |
The aim of this study was to verify that empathetic laughter may contribute to psychological and somatic health in human via coping with daily stressors. We regarded the emotional reactivity for laughter as a personality trait to empathize with other's positive emotions.On the other hand, sense of coherence (SOC) is dispositional orientation for effective coping and good health. Therefore, we hypothesized that emotional reactivity for laughter may associate with SOC. In this study we found 1) significant negative correlation between SOC score and the psychological and somatic symptoms, 2) the significance of SOC on the positive empathy-derived mood state. To evaluate the stress rescue effect of laughter, we first examine the functional connectivity during watching the laughter-inducing movie by event-related functional MRI. Data analysis showed that movie-induced laughter may associate with discrete regions including orbital part of inferior frontal gyrus.
