Advance planning of discourse in potential exchange situations



Advance planning discourse strategies are examined in an experiment where subjects expect to be in a communicative situation (discussion vs appraisal) with another speaker (expert vs peer) whose opinions on a given topic differ diametrically from theirs.

Findings indicate that two complementary processes are implemented: one on the level of the components of the universe of reference (via predication operations) and the other on the level of relationships between actors (through hedges).
