In one subject state, Anna O only spoke English and German that she was addressed to was not “formulated” and understandable. However, Anna in the normal state, English phrases are foreign to her and more or less “unformulated”. Here, we are invited to assume that there be another notion
of dissociation, which might need to be indicated as DISSOCIATION or Dissociation in comparison with dissociation that was delineated by Stern and Bromberg.
In this paper we discussed the meaning of the notion of dissociation and the role it takes in the literature as well as clinical practice in psychoanalysis. In the history of psychoanalysis, the notion of dissociation has been under the shadow of the model of repression, Recent studies on dissociation draw on the past studies of dissociation done by multiple psychoanalytic thinkers and make it into more clinically useful ones. However, the author considers that the notion of dissociation is omitting one point,
which is that the unformulated and un-experienced dissociative part can be actually formulated and experienced by another subject of the same person. I proposed the notion of Dissociation which can covers this state so the theory can really be applied for wide range of dissociative pathology.
