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.

Follow your breath: respiratory interoceptive accuracy in experienced meditators.

Attention to internal bodily sensations is a core feature of mindfulness meditation. Previous studies have not detected differences in interoceptive accuracy between meditators and nonmeditators on heartbeat detection and perception tasks. We compared differences in respiratory interoceptive accuracy between meditators and nonmeditators in the ability to detect and discriminate respiratory resistive loads and sustain accurate perception of respiratory tidal volume during nondistracted and distracted conditions. Groups did not differ in overall performance on the detection and discrimination tasks; however, meditators were more accurate in discriminating the resistive load with the lowest ceiling effect. Meditators were also more accurate during the nondistracted tracking task at a lag time of 1 s following the breath. Results provide initial support for the notion that meditators have greater respiratory interoceptive accuracy compared to nonmeditators.

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.

Coherence between emotional experience and physiology: does body awareness training have an impact?

Two fundamental issues in emotion theory and research concern: (a) the role of emotion in promoting response coherence across different emotion systems; and (b) the role of awareness of bodily sensations in the experience of emotion. The present study poses a question bridging the two domains; namely, whether training in Vipassana meditation or dance, both of which promote attention to certain kinds of bodily sensations, is associated with greater coherence between the subjective and physiological aspects of emotion. We used lag correlations to examine second-by-second coherence between subjective emotional experience and heart period within individuals across four different films. Participants were either: (a) experienced Vipassana meditators (attention to visceral sensations), (b) experienced dancers (attention to somatic sensations), and (c) controls with no meditation or dance experience. Results indicated a linear relationship in coherence, with meditators having highest levels, dancers having intermediary levels, and controls having lowest levels. We conclude that the coherence between subjective and cardiac aspects of emotion is greater in those who have specialized training that promotes greater body awareness.
