At California Forensic Credibility Assessments we use the Stoelting CPS Pro model polygraph instrument.  The CPS Pro is a computerized polygraph instrument developed by Dr. David Raskin, Ph'D and Dr. John Kircher, Ph'D at the University of Utah, Salt Lake City, Utah.  Comprehensive validation studies were conducted under the authority of the National Institute of Justice and the United States Secret Service.  The CPS Pro software evaluates the body's psycho-physiological responses and computes the readings into the probability of truthfulness and deception.

EXPLANATION OF THE POLYGRAPH EXAMINATION AND PROCEDURE

The polygraph examination is a psycho-physiological detection of deception technique.  The polygraph examination utilizes computerized forensic testing instrumentation which records physiological responses into software designed by the manufacturer.  Relative changes in blood pressure, rate and strength of pulse rate, electro dermal activity and respiratory inhalation / exhalation patterns are recorded for analysis.

The polygraph examination consists of three separate and distinct phases; the Pre-Test Interview, the In-Test Phase and the Post-Test Interview.

During the Pre-Test Interview the polygraphist will explain your legal rights and the voluntary nature of the examination.  The polygraphist will also discuss your medical, physical and psychological background.  In addition the polygraphist will go over your background information and will explain how the polygraph instrument works.  You will have the opportunity to discuss in detail any of your concerns.  If you made a mistake on your paperwork  or if you failed to disclose something, be sure to explain it to the polygraphist during the Pre-Test Interview.

During the In-Test Phase the polygraphist will review all pertinent test questions with you and will then conduct the Acquaintance Test to help assess your suitability for testing.  Several tests will then be conducted which will include the previously reviewed questions.  There will be no surprise test questions, all questions will be reviewed with you in detail.  The polygraphist will then analyze the results of each test.

During the Post-Test Interview the polygraphist will discuss the results of the In-Test Phase and will then provide you with your test results.
