The purpose of this paper is to propose and discuss certain theoretical supositions, concepts and notions which are constituent elements of a psycosocial framework necessary in the approach and study of urban everyday life and common sense, viewed from a discursive perspective that has been developing over the last ten years. Some of our main references are general propositions of social constructionism (Gergen, 1985; Shotter & Burton, 1983), discursive psychology (Billig, 1991-94; Parker, 1995-96), and hermeneutics (Riccoeur, 1998; Gadamer, 1979). In this manner we adopted discurse analisis as a basical methodological strategy to explore dis-cursive productions comming from: people ("live discurse"), local political institutions ("official discurse") and local mass media ("public discurse"). Some theoretical supositions are asumed here: a) the city is a semantical being which produces its own discurse and induces citizens to generate it too; b) discurse is a psychosocial and cultural founda- tional praxis: which is founded by discurse and the reality it talks about; c) the city's realities are not an a priori data which exists independently of individual thinkers, but a complex historical process-product constantly rebuilt by people; d) common sense is a transdiscursive dimension heavely charged by the semantic sedimentation of words and popular expressions comming from history and traditions.
