Testimonial career: an operator of the dynamics of memory and communication

If the witness becomes a part of the relationship between memory and communication, we contribute to the evolution of research on the testimony, particularly exposing the individual and collective patterns that form the basis of the gesture. Drawing on the work of interactionist sociology, in particular occupational groups, we propose in this article to trace key moments in the career of a witness and clarify the evolutionary relationship that he has with a group and / or society.
