This dissertation, which is both exploratory and descriptive in nature, initially describes the development of the polygraph against a background of understanding society's rejection of the lying phenomenon. The theoretical foundations of polygraph thinking are then presented as forerunner to practical illustration of polygraph use in the private sector. The criminal justice system represents the sphere of polygraph ulitization central to the research. With strong American accent, polygraph use in all four components of the system is described in such a manner so as to provoke thought on the part of criminal justice functionaries as to polygraph possibilities in the execution of their functions. Research findings and recommendations aimed at stimulating thought and improvement in the field of polygraphy conclude the dissertation. === Criminology === M.A (Penology)
