The influence of sexual stereotypes on gender development is somewhat cyclical. Adults learn about gender roles from children, and children imitate those roles based on their own biological sex. While adults treat boys and girls differently, children tend to follow the gender expectations they see around them. Sometimes, however, children are treated according to gender stereotypes that may not fit their actual gender identities.
In the 1970s experiments revealed that adults play differently with babies depending on whether they know their sex or not. There were also marked differences between the attitudes of men and women to the child. As soon as they are born, children start developing a sense of themselves as individual people. Adults reinforce gender stereotypes, including the submissive, emotional, and empathetic nature associated with girls and the independence, reasonableness, and toughness associated with boys.
