The observations presented above seem to prove that the threshold of sensory perceptivity is a mirror of the instinctual equilibrium, and that a close study of abstract reactive sensory behaviour can provide the analyst with indications for the patient's development of early object relationships. In brief, what has been reported here constitutes a recommendation for analytic research into preverbal expressions of the unconscious or preconscious during the analytic procedure. The appearance of certain inter-sensory forms of behaviour is a precursory expression of the conflictive relationship to certain objects of the past. These preverbal sensory expressions disappear when the corresponding instinctual conflicts are settled.

Dissolution of the patterned sensory complex is an essential purpose of psycho-analytic therapy. Therefore, the scrutiny of the changes in sensory behaviour can be used for the evaluation of the therapeutic process, of its result, and—when we are engaged in therapy—as an adjuvant to know why we do what we are doing.
