Coping with mate poaching: gender differences in detection of infidelity-related threats

People often aspire for true love and committed romantic relationships. These relationships, however, are recurrently threatened by partner infidelity. The present research tested a new infidelity-detection model, the rivalry sensitivity hypothesis, that posits that women are more sensitive to cues of infidelity than men are, and tend to focus their attention on potential rivals in their mate's vicinity, whereas men show increased sensitivity of their own partners. In a series of four studies, we found that women displayed greater alertness to cues of potential partner unfaithfulness than did men, were quicker and more accurate in detecting cues of infidelity, but were not better than men in detecting other threats. Women also focused their attention on potential rivals (other women), whereas men's attention was specifically directed at monitoring their own partner's intents. These findings suggest that women and men have developed different strategies aimed at achieving a similar outcome - mate retention.
