How It Works

What is a polygraph?

A polygraph is a general term for several scientific detection of deception instruments. Questions are asked requiring a yes or no for an answer. The questions are the stimuli which create the physiological responses which are charted.

The polygraph consists of 3 or more components. The basic components are made up of the cardiosphygmograph(bloodpressure cuff), pneumo and the galvanograph.

The cardiosphygmograph records your relative blood and pulse rate, the pneumo records breathing and movement and the galvanograph records resistance.

At the beginning of the examination, a pre-test interview is conducted. This consists of explaining the polygraph and attachments as well as a deep interview with the examinee to help in development of the questions for the examination.

Once the pre-test interview is finished the questions to be asked on the polygraph are developed and discussed with the examinee. The attachments are then placed on the examinee and the test begins. A total of 2 to 3 charts will be conducted lasting 1 1/2 to 3 hours. Upon completion of the examination the charts will be examined and the results given.

The accuracy of the polygraph has been found to be around 95%. The polygraph has been in use for over 75 years. More than 250 studies have been conducted on the accuracy of the polygraph. Some states allow the results of the polygraph in court proceeding, but not all. But all states do allow the use of polygraph and are used in all major police departments and all Federal Judiciaries.

Most individuals are nervous about being tested. A good examiner will relieve some of the stress and reassure a truthful examinee the results will be positive.

My hours are very flexible. I am available everyday, night or week-end.

Every test I administer is kept confidential. Any information I obtain from a client stays with me and is kept strictly confidential.
