Abstract
Freud and Breuer proposed the concept of splitting of the mind and described it in various clinical cases and the concept was later developed in studies by Klein, Kohut, Kernberg and others. These basic clinical findings were also confirmed by later studies using Rorschach projective test documenting that splitting in mental structures may be observed in phantasies and associations reflecting cognitive and affective contents related to conflicting interpretations of objects, other persons and the self.
Altogether these data indicate that splitting represents a specific form of dissociation resulting from a conflict that leads to splitting of the ego and other parts of the psychic apparatus into separated subsystems. In this context, splitting and dissociation do not mean different terms even they are used in different contexts for description of specific conditions that may occur in various mental disorders.
