The temporal dynamics of emotional acceptance: Experience, expression, and physiology.

Emotional acceptance has begun to attract considerable attention from researchers and clinicians alike. It is not yet clear, however, what effects emotional acceptance has on early emotion response dynamics. To address this question, participants (N = 37) were shown emotional pictures and cued either to simply attend to them, or to accept or suppress their emotional responses. Continuous measures of emotion experience, expressive behavior, and autonomic responses were obtained. Results indicated that, compared to no regulation, acceptance led to more positive emotions, transiently enhanced expressivity, and lowered respiratory rate. Compared to suppression, acceptance led to more positive emotions, stronger expressivity, and smaller changes in heart rate, blood pressure, and pulse amplitude, as well as greater oxygenation. Acceptance and suppression thus have opposite effects on emotional response dynamics. Because acceptance enhances positive emotion experience and expression, this strategy may be particularly useful in facilitating social interactions.
