A lifespan perspective must be considered when discussing gender normalization. But one must also consider cultural hegemony in this stage of the lifespan as a child develops more of an understanding of their culture and begins to display original ideas of cultural norms as well as social norms. According to the constructivist emphasis, the man/woman dichotomy is not the "natural" state, but rather a potent metaphor in Western cultures. Building social relationships and developing individuality are essential benchmarks for this age of middle childhood, which ranges from eight years old to puberty. A young boy is trying to navigate falling within the social structure that has been laid out for him, which includes interacting with both sexes, and a dominant notion of maleness. The gender environmentalism, which emphasizes the role of societal practices in generating and maintaining gender differentiation, still plays a part in this stage of life, but is possibly more influenced by immediate and close interactions with boys close to their age. The boys organize themselves in a hierarchical structure in which the high-status boys decide what is acceptable and valued – that which is hegemonically masculine – and what is not. A boy's rank in the hierarchy is chiefly determined by his athletic ability.
