Lie detection test has been followed in interrogation of suspected criminals for years now. In fact, a lot of employers too have started to conduct lie detector test as part of employee background check curriculum. As part of the test, you will be connected to a polygraph or lie detector machine. You will be asked a series of questions. As you start to answer, the polygrapher will assess your score by comparing your physiological responses in respect to the questions asked. Now, the very mention of “lie detection” could trigger stress in many even when they are innocent which might lead to misleading responses. Have you too been asked to sit for a lie detection test? Well, nothing to fret, the post below offers a brief on how to pass the test with flying colors.
Understand questions and required reactions
First of all, you should know that you would be asked three kinds of questions- relevant, irrelevant as well as control questions.
The irrelevant ones are those that generate obvious answers. For example- “Where do you stay?”
The relevant ones are those bear direct relation with the specific reason behind lie detector test. For example, if a crime suspect is asked for the test, the control questions will be directly linked to the alleged crime.
The control questions are those which could be indirectly related to the particular reason behind your lie detection test and might refer to your past deeds. Responses received from control questions will compared with those received from relevant questions.
You need to come up with contradictory reactions in relevant and control questions. In regards to relevant questions, you should stay calm and at ease. Do not show any signs of hesitation while answering relevant questions. Maintain the baseline breathing rhythm.
On the other hand, you have to stay tensed, confused, fearful and upset while answering control questions. One way to do this is to solve difficult math puzzles in your mind. You can also revisit a fearful memory to excite yourself.
Be concise with your answers
Try to limit your answers to a simple “No” or “Yes” as much as possible. Refrain from divulging any further detail. But, that doesn’t mean you have to be impolite or non-cooperative. Be courteous, cooperative yet not over-friendly. If you are asked to offer elaborate explanations of a questions, politely assert you really don’t know much about that.
Don’t just blurt out answers on the test questions. Rather you should make sure to listen properly to each question asked. If there is something that you can’t understand, don’t hesitate to ask about the question again. Think well and then answer. Be clear with your tone so that the test professional doesn’t miss out on any of the words.
Manage your BP
Try to maintain strong control on blood pressure while you appear for lie detection test. Strategic breathing will help you here.
Maintain normal breathing pace with 15 to 30 breaths a minute. You have to maintain this particular stance throughout your test, just except during the control questions. Never breathe too deep. You will have to alter the breathing rate while answering control questions. Hold breath for two seconds after exhalation. Shallow breathing would be helpful here. Continue this for 15 seconds. Then, return to usual breathing pattern as the poygrapher takes you to next question.
Prepare answers beforehand
Lie detector tests are conducted to attain a specific finding. When a person is called for the test he already knows the reason behind the verification. Thus, he can also comprehend what kind of questions he could be asked to figure out the truth. It would be better if you can pile up a line of possible questions that you might be asked at the test. Once you do that, prepare the answers that you are going to give in response to questions. Practice this Q & A session at home to prepare yourself mentally about the test.
Stay hydrated and sleep well
Make sure to sleep well the night prior to your polygraph test. You can watch your favorite movie or read a fiction. The point is to stay relaxed so that the next day you can wake up with a refreshed mind. Do not drink alcohol or take drugs or sleeping pills.
