Emotion dynamics and responsiveness in intimate relationships.

Responding appropriately to an intimate partner's emotional signals and needs requires that one's emotional responses be reactive to significant interpersonal experiences. The adaptive function of emotions is likely compromised if an individual's emotional states are insufficiently attuned to interpersonal events. The present studies examine how individual differences in moment-to-moment emotion dynamics affect interpersonal responsiveness and relationship satisfaction. Study 1 examines associations between emotion dynamics and emotional reactivity to positive and negative relationship events. Emotion dynamics were operationalized using assessments of emotional inertia, which is defined as the degree to which emotions are resistant to change over time. Momentary assessments from 44 participants were collected four times per day over 4 weeks. Emotional inertia showed a curvilinear association with context-sensitive emotional responses to conflict, with individuals high or low in emotional inertia experiencing blunted emotional reactions to conflict. Study 2 assessed emotion dynamics based on four emotion reports per day over 10 days of both partners in a total of 103 couples. Associations of emotion dynamics with perceptions of partners' responsiveness and relationship satisfaction over 12 months were examined. Partners of individuals with high (inert) or low (erratic) emotional inertia perceived them to be less responsive, which then predicted steeper declines in their relationship satisfaction across 12 months. The results suggest that individuals with inert or erratic emotion dynamics exhibit less context-sensitive emotional responding to conflicts and are perceived by their partners to be less responsive which subsequently undermines the quality of their intimate relationships.
