Quantitative analysis of communication processes

The extraction of information on communicative process evolution starting measured values is the objective of this work. 250 psychological research interviews have been evaluated. The nature intrinsically interactive of the dialogue concretises, shapes and evolves within time dimension. Our approach founds on analogies between conversation processes and chaotic systems: in both of them time evolution shapes, defines and characterises the process. During the interaction, the turn alternation is fundamental, specially when the mutual definition of the relationship involves the acknowledgement of different roles. A reciprocal adaptation, where each partner learns, step by step, to lead in the interlocutor's reference frame, without quitting its own, turns into a common system exceeding those of both fellow. The " conversation process phase-portrait" have been estimated. This procedure allowed information extraction on the communication evolution: plots with anomalous paths indicate situations where the communication has been troubled from external references.
