The present study deals with the influences of active social support and mental activation of social support on cardiovascular reactivity, emotional states, cognitive appraisal and post-task rumination in high and low compassionate individuals. It was assumed, that social support functions as stressbuffer and results in a more adaptive stressprofile concerning the cardiovascular reactivity, the mental states, the cognitive appraisal and the post-task rumination. Highly compassionate individuals should profit more by social support, than individuals whose compassion is lower, because those people are constructing a better social environment for themselves. A total of 60 normotensive women were tested, half of them with high compassion, and the other half with low compassion. Twenty of them received active social support, another 20 received mental activation and the last 20 women received no social support at all. None of the expected effects postulated for cardiovascular parameters and emotional states could be confirmed. Concerning cognitive appraisals, the study indicates, that social support resulted in perceiving the task as less threatening and their own abilities as better in individuals who received active social support compared to those who did not receive social support. Social support also resulted in experiencing tasks as easier compared to no support. Highly compassionate women, who received active social support, showed a lower degree of negative rumination, than those women, who mentally activated their best friends. Additional results indicate, that highly compassionate women experience social support as more effective, and generally receive more support in their everyday life.
