ABSTRACT
In terms of facial expression, it is important to show one’s agreement with a nod to what the other says and to seek to provoke in him the same type of non-verbal response. Reciprocity of glances plays an important role in creating a good relationship and increases the possibility of a final agreement. The words coincide with the completion of an action, and the so-called “performative linguistic acts” are intended to literally create new realities where the situation so warrants. A prescription that represents injunctive language, that is to say of the language that does not explain but encourages to do, is the one we give to patients who are suffering from obsessive compulsive disorder, and who must check a number of times that they have performed an action well so as to reassure themselves.
