Over the lifetime of Conversation Analysis (CA), scholars have discovered many systems of action organisation (machineries) describing how conversational turns occur, what actions are expected, and how intersubjectivity in conversation is maintained. However, when John Heritage proposed a new machinery that examines the knowledge orientation of participants in interactions, a debate broke out between conversation analysts in which Michael Lynch and his colleagues in radical ethnomethodology descend upon on epistemics. The controversy begins with Lynch accusing Heritage of cognitivism and the (...) extra-situational nature of epistemics, while research on ethnomethodology and conversation analysis has traditionally focused on situated action. The discussion of epistemics points to an internal tension in CA as to where the boundaries of situations lie and what, therefore, can be the focus of CA. This article reactualises the problem of situationality in CA by analysing the arguments in the debate on epistemics. The authors show that epistemics and the debates surrounding it constitute a serious test for CA, revealing a conceptual problem that has hitherto been obscured - the relation and potential hierarchy of different machineries. Turning to the origins of the concept of situationality in the writings of Goffman and Sacks, the authors demonstrate that for opposing sides, the localisation of phenomena within situations is an analytical decision about what can be seen in empirical data. In contrast, distinguishing between the position of the analyst and the participant in the interaction shifts the analyst's attention to how the machineries become relevant to the interactants, that is, how their omnirelevance is realised. The authors argue that this is a more productive formulation of the question than that of the boundaries of the situation. (shrink)

Since the 1940s Harold Garfinkel developed ethnomethodology as a distinctive sociological attitude. This sociological attitude turns the focus of the analysis of interaction to the actor’s perspective. It suggests that interaction is ongoingly produced through actions that are organized in a retrospective and prospective fashion. The ethnomethodological analysis of interaction therefore investigates how actors produce their actions in light of their analysis of immediately prior actions and in anticipation of possible next actions. Ethnomethodologists describe the relationship of actions emerging from (...) this analysis as “sequential”. This article discusses how Garfinkel’s description of practical action as “experiment in miniature” can be seen as a precursor to the concept of “sequentiality” that defines today’s ethnomethodological analysis of interaction. Having discussed the intellectual background to ethnomethodology the article briefly explores two fragments of interaction audio-/video-recorded in a museum and an optometric consultation to illustrate the key concerns of this kind of analysis. The article closes with a short reflection on current developments in ethnomethodology and their relationship to sociology. (shrink)
