Close relationships

What motivates people to go out of their way to do things for their loved ones? Are loving feelings the only -or even the best- predictor of what we think we’ll do and what we’ll really do for our romantic partner?

In my research on close relationships I am interested in identifying the factors that contribute to prorelational behavior. In previous research we have identified that very different intrapersonal factors determine what is promised to a partner and what is actually being done. People make overly enthusiastic promises because they love their partner, yet they fall short of the promised behaviors not because of a lack of love but because of insufficient self-control strength. We identified situational factors that determine when the effect of love on prorelational behavior might be relatively stronger or weaker. For example, when a prorelational behavior can be done immediately, feelings for the partner are more important than levels of self-control – but the reverse is true if the prorelational behavior is delayed or has to be sustained over a longer period of time.

We are currently investigating how the link between feelings and prorelational behavior holds up under stress – do people who are highly committed to their relationship manage to uphold their relatively higher levels of immediate prorelational behavior in busy times, do their efforts collapse to the level of uncommitted partners, or do they activate remaining resources and do more for their partner under duress than regularly?
