As well as sending our brains into social overdrive, research also shows that eye contact shapes our perception of the other person who meets our gaze. For instance, we generally perceive people who make more eye contact to be more intelligent, more conscientious and sincere (in Western cultures, at least), and we become more inclined to believe what they say.
Of course, too much eye contact can also make us uncomfortable – and people who stare without letting go can come across as creepy. In one study conducted at a science museum, psychologists recently tried to establish the preferred length of eye contact. They concluded that, on average, it is three seconds long (and no one preferred gazes that lasted longer than nine seconds).
Players practice it. Chicks respond to it.
Another documented effect of mutual gaze may help explain why that moment of eye contact across a room can sometimes feel so compelling. A recent study found that mutual gaze leads to a kind of partial melding of the self and other: we rate strangers with whom we’ve made eye contact as more similar to us, in terms of their personality and appearance
If she holds your eyes for those three seconds, go talk to her immediately. This chick is an example of eye contact’s power.
