Scientists from Harvard and MIT have discovered that human brains tend to perceive a face as either male or female depending on where it appears in our field of view, according to a recently published study.

On a computer, the team generated a number of faces ranging from extremely female, to androgynous, to extremely male. They then flashed these faces at various locations on a computer screen and recorded which gender the subjects observed.

The researchers discovered that more androgynous-looking faces, when shown in certain parts of the visual field, would sometimes look male and sometimes look female.
