In this text we approach the National Exhibition of Psychological Practices from de concepts of archive and testimony. Considering the Exhibition as a collective archive it can be seen as a common ground of a multitude of enunciation that, as a testimony, expresses what have been and what Psychology is becoming as a science and as a profession.
