“At birth, girl babies look longer at faces than do boy babies, who look longer at mechanical toys. Later in life, girls are more prosocial than boys, better readers of facial expressions, more attuned to voices, more remorseful after having hurt someone, and better at taking another’s perspective.32 The same differences have been found in self-report studies of human adults.”
