What is Lie Detector?

What is Lie Detector and how does it work?

Polygraph (from Greek πολύ – many and γράφω – to write, synonym “lie detector”) – the device measuring the list of changes in a vegetative nervous system (blood tension, perspiration, the breathing and heart beating frequency and other peculiarities). This information is marked in polygram in a special program. After calculation of this psychophysiological information, polygraphologist comes to a conclusion about which of the questions were answered truthfully and on which lied. All the information got during the testing is given to the customer in a form of report. 

The service of instrumental lie detection is relatively new, but more and more leaders of different organizations of Krivoy Rog use this method for controlling their employees and finding out the truth in critical situations.
