This cultural and psychological study of gender identity and sexual development in a New Guinea Highlands society includes rich material on initiation rites and socialization studies, and contrasts the Sambia with other societies, including the United States. For example, Sambia boys experience ritualized homosexuality before puberty and continue this practice until marriage, after which homosexual activity is prohibited. The implications are developed cross-culturally and contextualized in gender literature. This new edition contains updated information about the Sambian ritualization and socialization of gender practices and will include a new chapter on sexuality, gender and social change among the Sambia.
