Once embedded in the Narrative Analysis theoretical-methodological framework (cf. Riessman, 1993, 2008), the current qualitative and interpretative research aims to investigate performances from people with aphasia, regarding stroke stories construction, in order to understand how narratives are built in collaborative ways and how storytellers construct identities for themselves and the others, and how they build surrounding realities, throughout stroke episodes they have reported. The assumption of the concept of language as a social and cultural symbolic system (cf. Schiffrin, 1994), the interface between studies on canonic narratives (cf. Labov and Waletzky, 1967; Labov, 1982) and interactional ones (Sacks, [1968] 1992; Jefferson, 1978; Norrick, 2007; Garcez, 2001), and the sense of narratives as a social, cultural and interactional construction, constitute the background of the undertaken analysis. Along with it, comprising the basis of the current research, studies on performance and identity are highlighted, guiding one to the understanding that story telling is not an act restricted to organizing past events in a temporal and causal order, but, above all, it applies identity and relationship construction (cf. Bruner, 1990; Bastos, 1999, 2004, 2005, 2008). Subsidized by the mentioned theoretical and methodological framework, counting on Ochs and Capps analytical tools (2001) and on approximately 15 hours of face to face interaction video recordings from people with and without aphasia in focal groups, from which 3 stroke narratives were extracted to be analyzed, the investigation led to the possibility of seeing: i) the active engagement of storytellers with aphasia to the interactional means of to embed narratives in surrounding discursive activities; ii) the turn to turn of narrative formation as an interactional enterprise; iii) co-storytellers actions to shape up the report, making it possible to keep a maintenance process over the ongoing interaction´s inter-subjectivity; iv) structuring stories as narratives that full fill temporal and causal organization requirements; v) the relevance of collaborative ways to the formation of narrative linearity; vi) storytellers with aphasia high performance expertise when selecting resources used to build tellability; and vii) distinct ways chosen by the three storytellers in order to construct themselves, others and reality, through stroke episodes they have reported. The current research outcomes show narratives embeddedness in surrounding discourse and social activity, the engagement of multiple storytellers to the narrative, linearity regarding stories, tellability and that different moral stances consist on interactional negotiations that participants are in charge of (primary storytellers and co-storytellers), instead of being an a priori imposition of local (discursive) and socio-cultural contexts. It highlights the theses that narratives are constructions related to here and now, throughout interaction processes. Besides, the fact that storytellers present aphasia underlines the interactional and collaborative features of storytelling, given the frequent penetration of somebody else´s actions in the course of narrative constructions.
