How Do Lie Detector Tests Work Operation Ouch Nugget Youtube You might see lie detectors on television shows, but do they actually work? can a machine tell if you're lying? greg foot explains how lie detectors work.sub. View our channel. experts explain how lie detectors work, what happens in the brain when we tell lies and how accurate polygraph tests are. and can manage to stay calm during a lie. Even the term "lie detector," used to refer to polygraph testing, is a misnomer. so called "lie detection" involves inferring deception through analysis of physiological responses to a structured, but unstandardized, series of questions. the instrument typically used to conduct polygraph tests consists of a physiological recorder that assesses. When a person takes a polygraph test, four to six sensors are attached to him. a polygraph is a machine in which the multiple ("poly") signals from the sensors are recorded on a single strip of moving paper ("graph"). the sensors usually record: the person's breathing rate. the person's pulse. the person's blood pressure.

Tubing runs from the cuff to the polygraph. as blood pumps through the arm it makes sound; the changes in pressure caused by the sound displace the air in the tubes, which are connected to a bellows, which moves the pen. again, in digital polygraphs, these signals are converted into electrical signals by transducers. The modern polygraph, better known as the “lie detector test,” is a fascinating little instrument with a long and controversial history. the earliest version a polygraph instrument was.
