The present paper reports some preliminary results of an on-going investigation which focuses the cognition process by which academic tests organize, relate and understand professional experience, specially, those who are focused on quality of communication as part of the field of quality management.
This presentation aims to show the results of an analysis that explores the interpersonal features in legal discourses, focusing modality; it is interested in the way Brazilian lawyers use the Portuguese language to convince judges to reformulate their decisions.
Results suggest that most of the uses of modality express meanings of obligation and necessity, in both negative and positive propositions, realized by modal operators such as não pode, deve, and tem que in Brazilian Portuguese (corresponding to can't, must and should, in English).
