Abstract

"Notwithstanding the magisterial work of the psychologists H. H. Clark and A. Trognon, in comparison with sociology and linguistics a veritable psychology of dialogue still remains little elaborated. This paper analyses epistemological obstacles facing such an enterprise, arguing that dialogue can not be understood as a ‘window’ on the individual mind. A vision of dialogue as a process of collective thinking, with the exchange as the fundamental unit of analysis, is sketched out. Dialogue is a complex system, involving multidirectional relations between situational representations, communicative action and emergent thinking. Keywords: dialogue, collective thinking, interaction analysis, methodology, complex systems. "
