RESUMEN
Researchers have only begun to turn their attention to the role of self-control in communal action (rather than communal restraint) in relationships. Conflicting results from early studies indicate that the association between self-control and communal action may be quite complex, and potentially moderated by many variables. Here we investigate how relationship length may moderate the extent to which communal actions require self-control resources. In 5 studies, we investigated the role of self-control resources in implementing (Studies 1 and 2) and in choosing (Studies 3-5) communal actions for a romantic partner, as a function of the length of time partners had been together. The data supported the hypothesis that as relationships mature over time, communal actions may require less self-control to implement and may become a decisional default. These findings suggest that communal actions may be a more deliberative response in newer romantic relationships but a more reflexive response in more established relationships.
