The polygraph, or the lie detector is the special device created for identification of a lie and the truth, reacting to changes of blood pressure, pulse rate, breath of the person and other biophysical changes in his organism. Of course, to deceive this car, it is possible to try to use external irritants and to put the button to itself in footwear. Besides, you can spend sleepless night, drink a small amount of alcohol before check, take valerian tincture. However experienced polygraphologists usually at the very beginning of check ask the simplest questions to reveal your state. If on all questions you give the same reaction, the expert will not be able to expose your lie, but also he will not be able to accept similar test results. Most likely, after that your answers will be just cancelled.

Let it will be the description of weather or something similar, however from the main subject after all it is not necessary to leave, otherwise the expert will suspect that you try to confuse it and to confuse. If you cannot hide the emotions during lie detector test, try to transform the valid feelings to something similar. Replace passion with rage, and repentance humility.

4. One more phenomenon which needs to be controlled during similar check - blood pressure. When the polygraphologist asks you questions, just bite a tip of language or squeeze sphincter muscles. Only be careful of the fact that the mimicry can give you. Externally you should not give any signs of the hidden actions.

5. To control the breath, you have to know what in usual conditions of people takes only one breath within two or four seconds. Your breath should not become more frequent or be delayed as it can accelerate heartbeat and by that to cause suspicion in experts.
