Gender roles are culturally influenced stereotypes which create expectations for appropriate behavior for males and females.[1][2][3] An understanding of these roles is evident in children as young as age four.[4] Children between 3 and 6 months can form distinctions between male and female faces.[5] By ten months, infants can associate certain objects with females and males, like a hammer with males or scarf with females.[5] Gender roles are influenced by the media, family, the environment, and society.[6] In addition to biological maturation, children develop within a set of gender-specific social and behavioral norms embedded in family structure, natural play patterns, close friendships, and the teeming social jungle of school life.[6] The gender roles encountered in childhood play a large part in shaping an individual's self-concept and influence the way an individual forms relationships later on in life.[7]
