POLIGRAF – POLIGRAFSKO TESTIRANJE
POLYGRAPH – POLYGRAPH TEST

Summary/Abstract: The polygraph is a measuring instrument often called the „lie detector“ according to an English translation (lie detector). The polygraph is used to discover the truth and the elimination of innocent subjects in order to police the on-time and to indicate some guidelines at an early stage of the investigation. The polygraph after a whole century of application even today provokes contradictory opinions. The authors have tried to briefly explain the functioning of polygraph, who are the persons conducting polygraph testing and what categories of persons shall not be subjected to testing. Described the proposal recording polygraph tests for the possibility of subsequent review and thorough insight into testing. Researchers in Britain and the Netherlands have made a breakthrough, developing a method with a success rate in tests of over 70% that could be in use in police stations around the world within a decade. Rather than relying on facial tics, talking too much or waving of arms (all seen as tell-tale signs of lying) the new method involves monitoring full-body motions to provide an indicator of signs of guilty feelings. There has been a lot of scepticism in the scientific and legal communities about its reliability. By contrast, the new method developed by the researchers has performed well in experiments. The time will tell.
