[Etiopathogeneic aspects of inhibition. Psychodynamic approach to inhibition].

From a psychodynamic point of view it is not sure that the meaning of the term inhibition differs radically from the meaning of the same term when it is used in psychophysiology. It is stated in this paper that the psychodynamic point of view concerns the actions and inhibitions which can be seen as the non activation of an action with the substitution of a deplacement action. Inhibition of actions can be investigated in three clinical fields: intrapsychic and external conflicts, depressive reaction and psychotic lack of energy. It is clear that the psychological mechanism is not the same in the three kinds of disorders. In a second part, the authors try to bridge the gap between the psychodynamic point of view and the psychophysiological one.
