Gender Socialization
Gender Socialization is the process where a child learns our culture's gender norms, roles, and expectations. This is influenced by parents, teachers, the media, and peers.
In this example, the boy's peers are teaching him that "boys don't cry" through making fun of him. This leads to him wanting to stop crying, as he sees it as something that boys don't do. This is an example of the process of gender socialization.
