Frequently Asked Questions about Polygraphs

WHAT IS A POLYGRAPH?
According to the dictionary the polygraph is a measuring device, which makes a permanent recording of various physiological changes taking place within the body of the test subject, as a result of certain psychological stimuli. These stimuli are brought about by asking questions, structured and phrased in a specific way, and by maintaining a certain environmental and emotional climate during the examination.

During the pretest interview, the polygraph examiner will explain your legal rights, explain the polygraph instrument and how it works, discuss the issue, develop and review all questions asked on the polygraph test, cover general background information, and will provide instructions for the actual testing phase.

It is expected that anyone who takes a polygraph test will be nervous; however nervousness does not normally interfere with the test . Even though a person has high blood pressure, diabetes, etc., their body has a set of normal patterns on a daily basis. When a person decides to lie, however, physiological changes begin to take place in the body. Blood pressure begins to increase or decrease. Heart rate can increase or decrease. A person's heart can skip a beat. Blood volume begins to change. These are just a few of the types of physical changes that can occur. In the case of deception, more than one type of physiological change usually occur. The person taking the test must decide whether or not they are going to tell the truth, or whether or not they are going to lie and withhold information about the relevant issues. Once a person decides to tell the truth, the body goes about its normal patterns with no significant or consistent changes.

The polygraph consists of three or more components: the pneumograph component that records respiration and movement, the galvanograph or G.S.R. component records your galvanic skin response and changes in skin resistance, and the cardiosphygmograph component records your relative blood pressure and pulse rate. Once the pretest interview has been completed, the polygraph examiner will place four attachments on the subject's person: two rubber pnemograph tubes across the upper chest and abdomen, two metal fingerplates across the ring and index finger, and a bloodpressure cuff around the upper arm. During the collection of charts, the examiner will ask the reviewed questions two to three times, and run a minimum of two to three separate charts before rendering an opinion.

WHAT ABOUT ACCURACY?
The polygraph has been in use for over 75 years. During that time approximately 250 studies have been conducted on the accuracy of polygraph tests. Since conditions and factors involved in research will vary, and since a polygraph examination is a very complex process, it is difficult to extract a precise accuracy figure from the data. Nevertheless, the preponderance of available information indicates that the accuracy of a properly trained examiner, utilizing established testing procedures, is around 95% for specific-issue investigations. Some independent studies, however, place the figure as high as 98%.

HOW LONG DOES THE TEST TAKE?
A polygraph test consists of several different phases: a pretest interview, the collection of charts, and an analysis of the polygraph charts. The average polygraph test will usually last 2-3 hours from beginning to end. The longest part of the polygraph test will be the pretest interview, which normally lasts anywhere between 45-90 minutes.
