Action in connection with the therapeutic process is often equated with acting out. The subtle behaviour that belongs to “the complicated system of transmitting and receiving unconscious signals” (Sandler), with which the patient attempts to make the analyst behave as the object of transference or to fulfill an unconscious desire, is also described as acting out or micro-acting out (Treurniet). This fine-grained action, however, means nothing; it is not symbolic or communicative action. Its intention is, rather, to trigger effects and induce interactions. It occurs not only on the side of the analysand but also on that of the analyst, and is part of the unconscious communication in the therapeutic process. Presented here are some of the various interactive ways and means with which the analyst is prompted into unconscious action and certain, unnoticed, ways in that he turn “treats” the patient. The analyst's action responses can bear the character of interpretations with which he may unintentionally reveal how he regards the behaviour of the patient.
