Indian girl, father create truth gizmo

Deccan Herald (Internet / Print) 05/26/06 http://www.deccanherald.com/deccanherald/may262006/index2046222006525.asp An Indian teenage prodigy who has helped her doctor father develop a truth machine is attracting wide attention in the US. Tricia Pasricha is a 16-year-old high school student from Galveston in Texas who helped pioneer using the electrogastrogram, a machine that records the stomach’s electrical activity, as a way of measuring the stress of lying. Supported and encouraged by her father Dr Pankaj Pasricha, director of the Division of Gastroenterology at the University of Texas Medical Branch(UTMB) at Galveston, Tricia’s study suggests the digestive tract is uniquely sensitive to mental stress and that changes in gastric physiology perform better than standard polygraph methods used to distinguish between the truth and telling lies.
