An American sociologist has come up with a new study that attempts to shed light on why couples feel attracted to one another.
University of Notre Dame sociologist Elizabeth McClintock studied the impacts of physical attractiveness and age on mate selection and the effects of gender and income on relationships.
Her research offers new insight into why and when Cupid's arrow strikes.
"Couple formation is often conceptualized as a competitive, two-sided matching process in which individuals implicitly trade their assets for those of a mate, trying to find the most desirable partner and most rewarding relationship that they can get given their own assets," McClintock said.
McClintock's study showed that just as good looks may be exchanged for status and financial resources, attractiveness may also be traded for control over the degree of commitment and progression of sexual activity.
