The following pages present the methodology and results of a study conducted with interpreters from various training backgrounds who work in a variety of milieus and use different approaches. These professionals from Canada, the United States and Mexico were asked about their perceptions of their role and, in particular, about the visibility of the interpreter. This paper explores their responses concerning the position of the interpreter in relation to the parties communicating; his or her influence on the climate of trust, the communication of emotion, intercultural mediation and the direction of intervention.
