Henceforth, several psychological theories have attempted to explain and treat the narcissistic phenomenon. Specifically, the most comprehensive psychological theories have been advanced by the psychodynamic perspective and to a lesser extent the Jungian (analytical) perspective. Essentially, both theories cite developmental problems in childhood as leading to the development of the narcissistic disorder. The existential school has also attempted to deal with the narcissistic problem, although the available literature is much smaller. Existentialists postulate that society, as a whole can be the crucial factor in the development of narcissism. The final perspective is the humanistic approach, which although lacking a specific theory on narcissism, can nevertheless be applied to the narcissistic disorder. In many ways the humanistic approach to narcissism echoes the sentiments of the psychodynamic approach. .
The Emergence of the Narcissistic Personality .
According to Kernberg and the object relations school the crisis of the rapprochement subphase is critical to the development of the narcissistic personality. The individual who is unable to successfully master the challenges of this stage will sustain a narcissistic injury. In essence the narcissistic injury will occur whenever the environment (in particular significant others) needs the individual to be something which he or she is not. The narcissistically injured individual is thus told "Don't be who you are, be who I need you to be. Who you are disappoints me, threatens me angers me, overstimulates me. Be what I want and I will love you" (Johnson, 1987; P. 39). .
The narcissistic injury devastates the individual's emerging self. Unable to be what he or she truly is the narcissistically injured person adapts by splitting his personality into what Kohut terms the nuclear (real) self and the false self. The real self becomes fragmented and repressed, whereas the false self takes over the individual.
