Based on the theme of transmission, the author takes up two situations in this article, one clinical, concerning the review of a therapeutic mother/child consultation presented by Françoise Moggio at the Deauville colloquium, the other more personal, a group supervision sequence with Annie Anzieu. In analysing these two moments, the author takes up a theme developed in her previous work: transmission outside the realm of the spoken word, of that part of the unknown, of the unexpected, associated with the encounter with the mental life of the other, considered here in a new way on the basis of a training situation. If the emotional impact perceived on the analyst’s side gives rise to a transmission that can take the form of action rather than words, self-analysis and the work of countertransference offer the possibility of transformation.
