How do you know if someone is checking you out?
New research suggests that it may have something to do with how masculine or feminine a face looks.
Women were able to more quickly determine whether someone was looking at them when that person’s face was more masculine. The same is true with men, except they could make the determination more quickly when the face was more feminine.
Men were no quicker in determining gaze direction when looking at other men’s faces, nor were women able to more quickly determine gaze direction when looking at other women’s faces. This, the researchers say, suggests an evolutionary component is at work for mate selection.
