| professional psycophylogist, using an instrument that monitors physical reactions of the body when questioned about a specific issue. Polygraph instruments measure changes in blood pressure, movement and the amount of sweat on the skin surface. These changes take place when a person is giving a deceptive answer to a question. The polygraph is not a lie detector. If we could accurately detect lies we would not need a court system to determine guilt or innocence. Polygraphs examinations are used for a variety of situations. Some modern television programs have recently used the polygraph to see if a person is cheating on their spouse. While polygraph is sometimes used for this purpose it is more likely to be used for professional investigative purposes. Modern polygraphs have been scientifically validated. You can expect accuracy of about 90% for a single issue test. This is about the same as the accuracy of an MRI finding a breast cancer tumor. I use a modern Lafayette 4000 computerized instrument. This is considered by many professionals to be the "work horse" of the industry. Most people are surprised to discover that there are no surprise questions on a professional polygraph examination. The examiner will go through each question with the test subject before the exam begins. A typical test will take about three hours with about 45 minutes of actual chart time. The rest of the exam is spent in discussions about the test process and the event in question. If you have need of a professional polygraph examination, call for a free consultation. |
