FPDA analyses the ways in which speakers are 'positioned' by different and often competing 'discourses' according to Michel Foucault's (1972: 49) definition as 'practices that systematically form the objects of which they speak'. According to this, speakers constantly move between powerful and powerless 'subject positions' as they talk and interact. FPDA is influenced by a poststructuralist rather than a Critical Discourse Analysis (CDA) perspective: that is, the method is informed by the view that no speaker is wholly a victim and powerless, nor wholly dominant and powerful.
