When you identify which are the control questions, your goal is to have an exaggerated physiological response to them. Then your responses to the relevant questions will seem normal when compared to them by the polygraph examiner. That’ s true whether you lie or whether you just get nervous easily when asked accusatory questions. The primary ways to do this are by using your breathing and your heart rate.Get the facts at http://www.liedetector.uk website
Important Information on Lie Detector Test
Train yourself to breath comfortably at the same rate throughout the interview — until the lie detector test devices are removed from your body. During the exam, after answering a control question, do one of the following:
Breath more slowly for 5 to 15 seconds, then resume normal breathing before the next question. Hold your breath for 4 to 5 seconds, then resume normal breathing before the next question. Exhale more slowly than you inhale for 5 to 15 seconds, then resume normal breathing before the next question. Take several shallow breaths, then resume normal breathing before the next question.
Heart rate responses:
Teach yourself how to increase your blood pressure and heart rate, using your thoughts and your body. During the test, after answering a control question, do one of the following:
Quickly bite the side of your tongue hard enough to hurt a little. This will get your heart rate to speed up, and is less noticeable than using a tack in your shoe or other pain-inducing countermeasures. Practice this one in front of a mirror, so you aren’t obvious when you do it.
Use your imagination to speed up your heart. Quickly think of a car crash, a knife going into you, or anything that will provoke a fear response. If you have a vivid imagination, this is an easy technique to use. If not, practice while taking your pulse.
