Compassion meditation increases optimism towards a transgressor.

Past research reveals important connections between meditative practices and compassion. Most studies, however, focus on the effects of one type of meditation (vs. a no-intervention control) on a single expression of compassion (e.g. offering a seat) towards a relatable target (e.g. a person on crutches), without exploring possible mechanisms. Hence, few studies include different types of meditation, active controls, multiple ways to express compassion, unrelatable targets, and potential mediators. To this end, the present study compared the effects of mindfulness meditation with those of compassion meditation on different expressions of compassion towards a convicted murderer. Seventy-four participants were randomly assigned to a mindfulness meditation, compassion meditation, or active control class, or a no-class control. After an 8-week programme, we assessed compassion by giving participants the option of fulfilling a murderer's request that they write him and then coding those letters for empathy, sympathy, forgiveness, and optimism. Participants in the compassion meditation class wrote more optimistic letters compared to participants in the other three conditions, in part because they valued positivity more. No statistically significant differences emerged for the other expressions of compassion. We discuss the implications of these findings for our understanding of how meditation increases compassion towards unrelatable targets.

Buddhist-inspired meditation increases the value of calm.

Most studies of meditation have focused on "actual affect" (how people actually feel). We predict that meditation may even more significantly alter "ideal affect" (how people ideally want to feel). As predicted, meditators ideally wanted to feel calm more and excited less than nonmeditators, but the groups did not differ in their actual experience of calm or excited states (Study 1). We ruled out self-selection and nonspecific effects by randomly assigning participants to meditation classes, an improvisational theater class, or a no class control (Study 2). After eight weeks, meditators valued calm more but did not differ in their actual experience of calm compared with the other groups. There were no differences in ideal or actual excitement, suggesting that meditation selectively increases the value placed on calm. These findings were not due to expectancy effects (Study 3). We discuss the implications of these findings for understanding how meditation alters affective life.
