What is an example of a social construct that influences how individuals perform gender roles in society?

One example of a social construct that influences how individuals perform gender roles in society is the idea of masculinity and femininity. These concepts shape what people believe is "normal" behavior for men and women. For instance, society often expects men to be strong and assertive, while women are encouraged to be nurturing and gentle. This can lead to individuals feeling pressure to act in ways that fit these roles, even if it doesn’t reflect their true selves. For example, a boy might feel he should avoid expressing emotions because he wants to be seen as tough, even though he might actually feel sad or vulnerable.
