Therapeutic development in an early adolescent with underdeveloped ego autonomy was achieved by presenting either-or questions. This study investigated the process of developing the either-or questions, which leads to developing a personality structure based on the psychoanalytic systems (PAS) theory. PAS theory attempts to understand changes in personality functions in psychoanalysis from quantum-mechanical perspectives. By using the PAS theory, mechanical variables were extracted. The results of the analysis indicated eight stages: (1)Preservation of narcissistic space through either-or questioning; (2)Either-or questioning and the demand for a mark of victory; The client drives the therapist into active-aggressive oedipal victory space; (3)The therapist falls for the trap and drives the client to a need for oedipal victory through Freudian “negation” dynamics; (4)Clarifying castration anxiety; (5)Immobilization of "here and now" boundaries; (6)Releasing the micro quantum world; (7)Clarifying fluctuation of ego autonomy; and (8) Allowance of oedipal self (life) and castrated self (death) due to uncertainty relation; Experiencing being Schro dinger's cat. Thus, the birth mechanisms of either-or questioning were reconstructed, and the mechanisms of modifying and improving underdeveloped ego autonomy through either-or questions were identified.
