I gesti interazionali come risorsa per la gestione dell'alternanza dei turni

The interactional necessity to project the next phase of an activity, and also its projection and completion, are collective actions: speakers‟ actions are modeled ont hose of the audience and orient to possible recipients‟ replies, expansions and insertions. This is possible thanks to the visibility of the details of multimodal actions and the participants‟ orientation to this visibility.
Many practices and resources are systematically employed by participants, not only to realize the transition towards the next activity phase, but also to embody their sense of completeness of the previous activity phase, and to accomplish the public availability, recognisability and interpretability of their actions.We will analyze the way participants explicitly orient to the multimodal details of talk-in-interaction showing video-fragments and transcripts of two kinds of institutional interactions: Italian lawyer-client counseling and news interviews. Although those videos show the complexity of speech multimodal temporality and interactional behavior, they also display participants coming, through multimodal resources, to a shared definition of a coherent and significant event. They also show that participants systematically orient through their practices to the locally available details and towards their temporal unwinding and sequential positioning.
