Evolved traits such as intuitive skills have allowed individuals to quickly evaluate a suitable sexual partner in about 100 ms (Olson and Marshuetz, 2005; Willis and Todorov, 2006; Todorov, 2008). Having determined that someone is attractive at first sight, an individual may become emotionally attached to that person and communicate their affection via a copulatory gaze, in which the individual gazes into the other person's eyes for many seconds (Fisher, 1992). In this opinion piece, I discuss why an individual can become attracted to and emotionally attached to another person in an instant at first sight and I propose how such feelings may be requited and thus how love at first sight between two people can occur if the receiver of such attraction has similar attributes to the individual. © 2016 Grant-Jacob.
