Final answer:
Margaret Mead's research illustrated that gender roles and traits associated with masculinity or femininity are highly influenced by cultural context, as evidenced in her studies of New Guinea societies.
Step-by-step explanation:
Margaret Mead's research on gender roles in different cultures revealed that cultural influences play a significant role in shaping personality and gender characteristics. Contrary to the assumption that gendered behaviors are biologically determined, her findings suggest that these behaviors can vary greatly across cultures. In some societies like the Arapesh and Mundugumor, both males and females displayed traits that are traditionally associated in Western culture with being masculine or feminine. In contrast, the Tchambuli culture exhibited a reversal of these traditional gender roles. Mead's work in New Guinea, as detailed in her 1935 book Sex and Temperament in Three Primitive Societies, demonstrated that what is considered masculine or feminine is subject to the cultural context.
