The first section of this article argues for an approach to interrupti
on as a participant's, not an analyst's, phenomenon. For analysts, int
erruption is best treated as a topic, not a resource. The second secti
on examines how participants go about making interruptions OBSERVABLE
events in the flow of interaction - in particular, the ways in which t
hey claim violations of speaking rights. The third section considers s
ome of the ways in which such claims are responded to. In the final se
ction, it is suggested that there is a general need for a more systema
tic approach to the methods through which acts are constituted in term
s of the responses they receive.
