The still-extant culture of the Navajo Nation in the Southwest of the United States is so different from that of urbanized Western man that it forms a basis for analysis of different aspects of both cultures. In doing so it sometimes leads to more awareness of the traits of the contemporary Western culture than that of the Navajo culture. Topics about the Navajo include the history of the extermination of the Navajo horses, fundamental differences in the languages—the Navajo language being a verb-oriented language and English being an adjectival-based language system—and the differences in visual perception between Navajos and Westerners as exemplified by research into movie making.
