That more women like soap operas and more men soccer seems to be proven, and this fact has a genetic basis. A base that, just born, makes girls prefer to look at faces more than boys.
In the womb, in the first trimester of a baby's pregnancy, it is observed that in boys there is more fetal testosterone than in girls. Among children who had more fetal testosterone, once they were born, they looked less into each other's eyes, as demonstrated in a study by Simon Baron-Cohen in Cambridge, with his disciple Svetlana Lutchmaya.
The investigation consisted of filming 29 girls and 41 boys of 12 months of age to analyze how often the baby looked at his mother in the face. The girls were the ones who looked most at the faces of their mothers.
Later, along with another disciple, Jennifer Conellan, they studied babies of an earlier age, newborns with only one day of life. They placed two possible things to look at in front of 102 babies: their own face or a physical-mechanical mobile of approximately the same size and shape as a face.
Even in these newborn babies it was proven that the girls preferred faces and boys, the mobile.
This difference would be the beginning for the differences between the brains of both sexes, that men have a systematizing mind and women have a empathizing mind. The relative preference for faces would gradually be transformed into a preference for social relations.
Perhaps some parents of children may have detected some difference in this regard, although I imagine that few will have thought of putting an object in front of babies to look at with their faces.
I certainly cannot speak of differences between my daughters and their enormous eyes, looking at their faces, nor do I know if they look more at faces than children, what I know is that most seems to like football. He will have inherited it from me.
