It is a widely used methodology in many disciplines, particularly cultural anthropology, European ethnology, sociology, communication studies, human geography and social psychology . Its aim is to gain a close and intimate familiarity with a given group of individuals (such as a religious, occupational, sub cultural group, or a particular community) and their practices through an intensive involvement with people in their cultural environment, usually over an extended period of time . The method originated in the field research of social anthropologists, especially Bronisław Malinowski and his students in Britain, the students of Franz Boas in the United States, and in the later urban research of the Chicago School of sociology . </P> <P> Participant observation was used extensively by Frank Hamilton Cushing in his study of the Zuni Indians in the later part of the nineteenth century, followed by the studies of non-Western societies by people such as Bronisław Malinowski, E.E. Evans - Pritchard, and Margaret Mead in the first half of the twentieth century . It emerged as the principal approach to ethnographic research by anthropologists and relied on the cultivation of personal relationships with local informants as a way of learning about a culture, involving both observing and participating in the social life of a group . By living with the cultures they studied, researchers were able to formulate first hand accounts of their lives and gain novel insights . This same method of study has also been applied to groups within Western society, and is especially successful in the study of sub-cultures or groups sharing a strong sense of identity, where only by taking part may the observer truly get access to the lives of those being studied . The postmortem publication of Grenville Goodwin's decade of work as a participant - observer with the Western Apache, The Social Organization of the Western Apache, established him as a prominent figure in the field of ethnology . </P>
