Abstract
Despite the surge of interest in borderline psychopathology in psychiatric quarters, contributions from the perspective of psychological testing have been few. A brief delineation of the range of borderline psychopathology is offered. Broad trends in the test performance of patients within the borderline range are described with regard to: intelligence and cognitive operations, thought and language, reality testing, organization of affect, configuration of defenses, structure of the object world, dynamics and the interpersonal aspects of the test process.
