A new paper to be published in Cogntion and Emotion (Von Culin, Hirsch & Clark, 2017) addresses the question of to whom people express emotion. In two studies, perceiving that a partner cares for one’s welfare is positively linked to willingness to express both positive and negative emotion. People who generally believe partners care express more emotions than so others. Independently of such individual differences, people express more emotion to those within their social networks whom they perceive to be more caring. Perceptions that others care (and thus emotion expression) is partly determined by those others’ actual care. However, it is also the case that people project their own feelings of care onto partners leading to greater emotion expression.
