The Instruments Used in Testing
The CPS II Polygraph Instrument is one of the four models of computer polygraph systems that are in use to date. The computer polygraph system utilizes computer scoring of objective scoring analysis, magnitude analysis and probability analysis. In addition, most examiners utilize national standardized scoring in addition to the computer algorithms.
What Computer Polygraph Systems Record …
Two channels of respiration (thoracic and abdominal) from UFI Pneumotrace transducers.
The conductance of skin from silver-silver chloride electrodes (either reusable or disposable attachments).
Cardiovascular activity from a blood pressure cuff.
Finger pulses from a sensitive photoelectric plethysmograph. (Optional)
Skin’s potential from silver-silver chloride electrodes (either reusable or disposable attachments). (Optional)
Voice events from examiner and subject. (Optional)
Subject’s movement from an activity sensor placed on the seat of the subject’s chair or under the feet of the subject’s chair. (Optional)
Auxiliary channel that can be configured to record one of several measures, including skin potential, continuous blood pressure, EKG or others. (Optional)
Accuracy is also highly dependent on the skill of the polygraph examiner who conducts the test, the suitability of the subject and appropriate issues for the test.
Lafayette Analog Instrument
This analog system of polygraph utilizes an electronically enhanced system of modules that record breathing, blood pressure pulse rate and galvanic skin response for detection of physiological changes related to lie detection.
This instrument is still in current use by many examiners. The system is as accurate as the computer system. Do not allow anyone to sell you the bill of goods that the only accurate system for lie detection is the computer system. Both systems of polygraph testing are 95 to 98 percent accurate in the hands of a polygraph expert. My company utilizes both systems for the polygraph procedures.
Accuracy is also highly dependent on the skill of the polygraph examiner who conducts the test, the suitability of the subject and appropriate issues for the test.
As a Side Note
As in all professions, there are the individuals who are in business to make, take or pry valuable monies from your hands. The service of polygraph testing is an old scientific method that has come a long way. With the advent of the computer and the scoring polygraph system that was scientifically developed by the John Hopkins University in Utah, polygraph testing has progressed from the so-called lie box to the lie detector system now respected by the community and used in the federal courts.
Professional polygraph examiners should have no problem giving you their credentials to verify (who they are and how long they have been in business). Ask your examiner questions in reference to his or her background and experience. Do not be shy or you could be the next victim of the unscrupulous examiner who does not take his or her profession seriously. There are persons who have studied the polygraph procedure out of a book. Look out. Ask for references.
