Forensic Psychophysiological Detection of Deception (PDD)
Missouri Polygraph Service provides professional polygraph examination services to assist with the truth verification process.
People often refer to the polygraph as a "Lie Detector."
The polygraph does not actually detect lies, but it does record physiological responses to a series of questions presented to an individual by a qualified polygraph examiner using a validated / approved testing format. The examiner is then able to decipher the chart polygrams and render a diagnostic opinion as to the veracity of the subject being tested.
The forensic term for the polygraph exam is PDD - Forensic Psychophysiological Detection of Deception.
