Argumentation is generally conceived of as a dialogic activity between two or more participants. Nonetheless, it operates also at an intrapersonal level, in a soliloquy where protagonist and antagonist of the critical discussion are embodied in the same person. We argue this case by analyzing journalists’ argumentation about linguistic choices in newswriting processes. Empirically, we draw on data generated with progression analysis, in particular with cue-based retrospective verbal protocols. The data was produced by the journalists under investigation when they, while (...) watching video recordings of their text production processes, reconstructed and verbalized their decisions. In the detail analysis, we focus on one editorial by an experienced journalist of Corriere del Ticino, the main Italian-language newspaper in Switzerland. (shrink)
