With the question “What is ' discourse?' “ as the starting point, this paper addresses ways of identifying particular discourses, and attends to how these discourses should be distinguished from texts. The emergence of discourse analysis within psychology, and the continuing influence of linguistic and post-structuralist ideas on practitioners, provide the basis on which discourse -analytic research can be developed fruitfully. This paper discusses the descriptive, analytic and educative functions of discourse analysis, and addresses the cultural and political questions which (...) arise when discourse analysts reflect on their activity. Suggestions for an adequate definition of discourse are proposed and supported by seven criteria which should be adopted to identify discourses, and which attend to contradictions between and within them. Three additional criteria are then suggested to relate discourse analysis to wider political issues. (shrink)
