The Surprising Way Girls and Boys Behave Differently just Hours After Birth

It’s an age-old question: How much of the differences between the way men and women behave are a result of nature, and how much is nurture?

A new study could shed more light on this. It shows different behavior between newborn boys and girls could appear just hours after birth.

Researchers from the University of Cambridge believe forces at work before birth — like sex hormone levels, might play a role, or even that the changes are a result of a slightly faster cognitive development in newborn girls.

They showed newborns — only about 33 hours old — two videos. One was a human face, the other, an animated Newton’s cradle (swinging metallic spheres).

Both sexes spent slightly longer looking at the face than at the Newton’s cradle. But researchers found that girls spent proportionally more of their looking time on the face than boys did. (Read more from “The Surprising Way Girls and Boys Behave Differently just Hours After Birth” HERE)
