Three New Guinea social groups (the Arapesh, the Mundugumor, and the Tchambuli) are the focus of this influential 1935 work by anthropologist Mead. It was in this work that Mead first advanced the argument that gender differences in males and females has much more to do with the cultural conditioning of different societies than with any fundamental biological differences. She looked at the sex roles of the people in the three different groups and also explored the behavior of those people who are considered deviants by the societies to which they belong concluding that human behavior is "infinitely malleable."
