Many refer to the polygraph as a lie detector in New Orleans, LA.

The dictionary defines the polygraph as a measuring device that permanently records the various physiological changes taking place within the body of the test subject because 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.

The Function Of The Polygraph
The polygraph device, on a basic level, records the physiological responses of the individual who is attached to a polygraph apparatus.
The Data a Polygraph Records
When a person is deceptive, there are physiological changes that take place in the body. A polygraph monitors and records, breathing rate, the pulse rate of the heart, blood pressure, blood volume, and galvanic skin resistance.
Polygraphs Detect Physiological Information
Lies are not detected by the polygraph. A polygraph records the physiological deviations of an individual who is attached to the apparatus, as they respond to sequences of questions presented by a trained polygraph examiner. The test is in a legalized testing format. The examiner then interprets the chart graphs or polygrams to deliver a diagnostic judgment concerning the truthfulness of the test subject.
Employers have the right to have a polygraph administered to an employee suspected of deception that may lead to an economic loss to the company. The employer must convey the rational suspicion in a written format. Even if the employee has access to what may cause the company and economic loss, it does not mean that the suspicion is a reasonable one. Pertinent information is provided in the Employee Polygraph Protection Act.
The Accuracy Level Of A Polygraph
The American Polygraph Association has determined that the polygraph is eighty-five to ninety-five percent accurate. Research studies verify that the polygraph has a higher accuracy rating.
