Final answer:
The traditional view of gender roles assumes that masculine and feminine traits are mutually exclusive, with men and women expected to exhibit behaviors aligned with societal norms for their assigned gender.
Step-by-step explanation:
The traditional masculinity-femininity model for describing individual differences in gender-role behavior was based on the assumption that masculine and feminine traits are mutually exclusive. This means that traditional views held that men and women had distinct roles that did not overlap, with masculinity often associated with strength, aggression, and dominance, and femininity with passivity, nurturing, and subordination. These views are part of socialization from birth in many societies, where even infants are assigned colors that correspond to their biological sex, reinforcing the society's norms for gender roles. Moreover, occupational sorting in adulthood reflects these traditional roles, with men and women often found in professions stereotypically aligned with their assigned gender roles.
