Same problem as other lie detectors. It is basically measuring an emotional response. There's no good evidence that any lie detector can discriminate among different reasons for an emotional response (that's what the elaborate questioning protocols are _supposed_ to do). Classic example: the innocent who is worried about the outcome of the test will respond emotionally; the pathological liar (experienced, does it for a living) won't. It's difficult to validate this sort of thing. You need a situation where the outcomes of lying are real world, AND you have an independent means of verifying the lie. * PAUL K.
