In this article, I outline a relational-developmental conception of emotion that situates emotional activity within a broader conception of persons as holistic, relational beings. In this model, emotions consist of felt forms of engagement with the world. As felt aspects of ongoing action, uninhibited emotional experiences are not private states that are inaccessible to other people; instead, they are revealed directly through their bodily expressions. As multicomponent processes, emotional experiences exhibit both continuity and dramatic change in development. Building on these (...) ideas, I describe an intersubjective methodology for studying developmental changes in the structure of emotional experience. I illustrate the approach with an analysis of developmental changes in the structure of anger from birth to adulthood. (shrink)
