In American culture, we reveal whom we like and dislike just by the amount that we look at them. We generally look most at those whom we like . In general, people avoid looking at someone they don’t like.
As people increase their liking for one another, they increase the amount of mutual gazing that they do. (Mutual gaze is when two people are looking into each other's eyes). The most obvious example of this occurs along the continuum of relationships. Romantic relationships have the highest amount of mutual gaze.
