The borderline personality is located on the continuum from the norm when it presents only the borderline style. Pathology is only diagnosed when we encounter the borderline personality disorders. In relation to the ICD-10 and DSM-IV-TR classifications, psychological models of the borderline personality disorders present the core aspects of that pathology in a broader manner, emphasizing the issue of organization and structure of the borderline personality. They also create a possibility of looking at the personality disorders of that kind as a kind of continuum from the norm to pathology. When encountering a norm, we refer to a certain borderline personality type. People whose personality is of borderline type, do not reflect the entire depth of the borderline pathology. They are differentiated by: some kind of instability in relations with other people, tendency to polar (black-white) perception of reality, easy and fast transfer from idealization to devaluation and inclination to impulsive emotional behavior. Their own experiences are processed by them more emotionally than rationally, and feelings are expressed spontaneously and creatively.
