What is a Polygraph

Polygraph, (PDD) Psycho-Physiological Detection of deception, is also known as: Lie detecting, Truth verification, Lie detector, Truth detector, etc. It is an instrument that measures and records several physiological responses such as blood pressure, pulse, respiration, breathing rhythms, body temperature and skin conductivity while the subject is asked and answers a series of questions, on the proven theory that false answers will produce distinctive measurements.

Polygraph literally means "many writings" referring to several components used to measure physiological changes caused by the sympathetic nervous system during questioning. Polygraph testing has an extremely high success rate and accuracy, and is very effective in resolving typical crimes like theft, fraud and corruption.

Do not be misled. VSA, AVSA, DVSA, CVSA, LVA and MLVA, although methods of truth verification, is not polygraph. These methods of truth verification may have merit, but  lacks in extensive research and validity studies as polygraph.
