How Does a Polygraph Work?
As a child, did you ever lie to your parents or a teacher? It could have been to avoid trouble or to gain acceptance from others. The fact is, this is normal behavior for human beings.
As we tell these small lies, we appear calm and convincing. On the inside, your heart races, your palms start to sweat, and your stomach tightens. This is especially true if the discovery of the lie could result in consequences.
We never seem to lose these involuntary responses to a situation in which we must protect ourselves by lying. A polygraph instrument records the presence or absence of such responses and records them on a moving graph.
The polygraph examiner is a trained professional who can determine, with a high degree of reliability, when the responses your body produces indicate you are telling the entire truth.
People arrive at a Polygraph Examination for various of reasons. Just sitting in a Polygraph Examiner’s chair is very stressful and can be embarrassing. The Polygraph Examiner understands this and will do everything in his power to ensure your examination goes smoothly. Being nervous or embarrassed during the examination will not affect the results of the test. All of our tests are confidential and we strive to ensure your privacy is maintained.
The examination is completely painless and does not use injections, electrical shock, or drugs.
The examination will start with a detailed interview with the Examiner. The Examiner will formulate a list of questions that will be asked during the examination. These questions will be reviewed with the Examinee to ensure everyone is confrontable with the questions. Before beginning the test, the Examinee will know the exact questions that will be asked by the Examiner.
The Examiner will then attach the polygraph sensors to the Examinee’s body.
The polygraph instrument records changes in blood pressure, pulse, respiration, body movement, supplemented with a unit for recording the GSR (Galvanic Skin Response). All exams are audio and video recorded for quality assurance and training purposes.
Pneumograph tubes are fastened around the subject’s chest. A blood pressure cuff is fastened around one of the subject’s arms. Electrodes are attached to either the fingers, palm, or on the back of the hand. The attachments are lightweight and are designed to be easy to apply and minimally restrictive to the Examinee.
After all the attachments are made and the Examinee is ready, the test will begin.
We utilize the Stoelting Computerized Polygraph System. Stoelting is a worldwide leader in advanced Polygraph equipment.
Our computerized polygraph system records, stores, and analyze physiological changes during the exanimation. These physiological changes are scored utilizing a algorithm and a specialized scoring system that reports the probability that that Examinee is truthful or deceptive. The Examiner also scores the chart manually to ensure that the test results are accurate.
In essence, every test is scored two times. Once by the computer and then by the Examiner.
