Primarily polygraphs (AKA lie detectors) are being used for deception detection tests (DDT) in terms of knowing hidden and crucial information associated with crime or an incidence. Often, other factors, i.e., nervousness, fear, anger, etc. affect polygraph data negatively. In some cases, the subject could be highly trained to intentionally falsify the DDT results by practicing yoga, meditation, etc. Using few event-related potentials (ERP), along with continually measuring few polygraph test parameters on the subject would be helpful as an ERP component elicited in the process of decision making. The failure rate of polygraph is 60%, as recorded by the U.S. Customs and Border Protection (CBP) pre-employment polygraph screening program. This work will help investigators to augment polygraph sensing to determine deception.
