Initiating a romantic relationship invokes an approach-avoidance conflict between the desire for affiliation and the fear of rejection; optimally, people should selectively approach potential partners who reciprocate their interest. This may be difficult for anxiously attached people: They may be unpopular, and their ambivalence could lead to either a fearfully selective approach at the cost of missed opportunities or an unselective, indiscriminate approach at the cost of increasing rejection. Using a speed-dating paradigm, data were collected from 116 participants, and a signal detection framework was applied to examine the outcomes. For anxious participants, speed-dating attendance was motivated by loneliness. At speed dating, they were unpopular and unselective; they missed fewer opportunities but made more failed attempts. Anxious men made fewer matches than nonanxious men, whereas anxious women were buffered by having a response bias toward saying "yes" to potential partners. Attachment anxiety predicted outcomes above and beyond the powerful impact of attractiveness.
