We examine gender as a cultural construct enacted through social cognitive processes that are embedded within the self, social interactions, and societal institutions. The embeddedness perspective elaborates how the binary gender categorization can create quite real gendered outcomes and experiences even if gender differences are not biologically essential. These categories take on a reality outside of the mind of perceivers because the meanings attached to gender categories are shared by others in the culture, enacted in social interactions, internalized into self-views, and maintained by social systems. Societal institutions explicitly and implicitly organize around gender, producing gendered norms, roles, and expectations. These norms, roles, and expectations shape the nature of interpersonal interactions both within and across gender lines and an individual’s self-selected experiences. Critically, these social interactions and personal choices in turn create behavioral and cognitive confirmation of the gendered expectations of others. Gendered expectations and experiences become internalized into the self, including one’s own self-concept and gender identity. We close by examining implications of this perspective for gender differences and similarities in social cognition, as well as malleability and stability in gender cognitions and outcomes.
