Streszczenie
The aim of the study was to provide further evidence of the accuracy of indirect deception detection measures and to test the effects of informing those engaged in detecting lies of the actual reason for their observations. The results are important from the point of view of potential applications. The experiment was conducted in two phases. First, a group of college students was asked to describe honestly or dishonestly four of their acquaintances. The statements were videotaped. Second, the video-clips were shown to a group of undergraduate students randomly assigned to one of four experimental groups in which the participants were asked to assess: 1) the honesty of the senders by answering direct questions; 2) the honesty of the senders by answering indirect questions; 3) the senders by answering indirect questions; 4) the senders by answering direct questions. The results revealed that participants were able to distinguish between truth and lies most accurately when an indirect question was applied and that informing lie detectors of the real aim of their activity did not impair the accuracy of this method. The theoretical considerations and the implications for future research are discussed.
