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.

Previous studies have demonstrated that 1 function of positive emotion is the undoing of physiological arousal produced by negative emotions. These studies have used single-subject paradigms, in which emotions were induced by films in college-age individuals. In the present study, we examined the relationship between physiological down-regulation and positive emotion in a sample of 149 middle-aged and older married couples engaged in a 15-min discussion of an area of marital conflict. During the conversation, autonomic and somatic physiological activity was measured, and emotional behaviors were recorded and subsequently coded. We found that during 20-s periods of down-regulation (where physiology transitioned from high arousal to low arousal), couples showed an increase in positive emotional behavior compared with periods without down-regulation. The finding was quite robust, suggesting that the undoing effect of positive emotion generalizes across age, sex, and marital satisfaction. The advantages of using positive emotion as an emotion regulation strategy are discussed.

Alzheimer's disease (AD), frontotemporal dementia (FTD) and semantic dementia (SD) are neurodegenerative diseases that differ in their socioemotional presentations. Mutual gaze (i.e. when two individuals make eye contact) is a building block of social behavior that may be differentially affected by these diseases. We studied 13 AD patients, 11 FTD patients, 9 SD patients and 22 normal controls as they engaged in conversations with partners about relationship conflicts. Physiological reactivity was monitored during the conversations and trained raters coded mutual gaze from videotaped recordings. Results indicated that mutual gaze was preserved in AD couples. Mutual gaze was diminished in FTD couples while SD couples showed evidence of greater mutual gaze. SD couples also showed lower physiological reactivity compared to controls. Across patient groups, reduced mutual gaze was associated with greater behavioral disturbance as measured by the Neuropsychiatric Inventory, especially on the disinhibition and apathy subscales. These results point to subtle differences between the three types of dementia in the social realm that help to illuminate the nature of the disease process and could aid in differential diagnosis.
