Episode 152: Detecting Deception
Uncontrolled eye movements and an elevated pulse rate are among the common methods to find out if someone is telling the truth. But University of Arizona information management professor Jay Nunamaker says computer technology has identified 500 such cues through a lie detection system called "Avatar." He notes further development could allow the system to be used at airports and border crossings. Prof. Jay Nunamaker spoke with Leslie Tolbert, PhD, Regents Professor Emerita in Neuroscience at the University of Arizona.
