This paper displays that relational network theory (chiefly evolved by the American neurolinguist Sydney M. Lamb) permits us to account for aspects corresponding to intention or attention, and for “smooth communication” and “bumpy communication” (the latter is the dimension covering unintended meanings). Four slips of the tongue are pertinent examples thanks to which it can be identified how cooperation and intention are in a very intricate interaction together with the substantial parts of the individual traits: attention, private experience, egocentrism, and salience.
