After briefly reviewing various contributions to the concept of
splitting, the authors describe the clinical manifestations of this
defense. These include 1) inability to experience ambivalence, 2) impaired
decision making, 3) oscillation of self-esteem, 4) egosyntonic impulsivity,
and 5) intensification of affects. The authors then discuss the relevance
of such conceptualizations to the differential diagnosis and psychotherapy
of personality disorders.
