CPS SYSTEM The Computerized Polygraph System (CPS) is based on extensive laboratory and field polygraph research conducted at the University of Utah over a period of more than 25 years. CPS provides the polygraph examiner with a sophisticated and powerful computer-based system that supports the preparation and conduct of polygraph tests using state-of-the-art electronics, transducers and computer software. CPS analyzes the results objectively and independently. It supports analyses of polygraph data collected in forensic settings (specific incident tests) using the Comparison (Control) Question polygraph technique, as well as all other polygraph techniques. The primary analyses performed by CPS are not the traditional categorical diagnoses (deceptive, nondeceptive, and inconclusive). Instead, CPS calculates the probabilities that the subject answered each of the relevant questions truthfully or deceptively. CPS also reports the probability that the subject was truthful to all of the relevant questions as a group and any desired sub-combination of relevant questions. Our research indicates that CPS classifications of subjects as truthful or deceptive based on the probability of truthfulness are at least as accurate as those obtained from blind numerical evaluations of polygraph charts by polygraph experts. However, no procedure is absolutely accurate. Furthermore, accurate test outcomes require the use of appropriate question structures and procedures for conducting the test in appropriate situations and under proper conditions. 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. Therefore, Scientific Assessment Technologies, Inc. takes no responsibility and assumes no liability for the accuracy of any polygraph test outcome on any individual. Research and Development The methods for quantification of physiological reactions are based on more than 25 years of scientific research and field experience by Drs. Raskin and Kircher at the University of Utah. The CPS computer analysis algorithms have proven to be very effective in providing automatic and objective analyses of the probability that a subject was truthful or deceptive on the test. The CPS quantitative methods and algorithms are unique in the polygraph industry. They are the only methods for computer scoring that produce high levels of accuracy and have been scientifically verified and published in peer-reviewed scientific journals. Other organizations and manufacturers of computerized polygraph systems have made claims of scientific verification and similar high rates of accuracy. However, none of their claims has been subjected to appropriate scientific scrutiny and verification. The unique experience and capabilities of Scientific Assessment Technologies, Inc. (SAT) have provided polygraph examiners and decision-makers with stateof- the-art instrumentation and scientifically based methodology for over 12 years. The University of Utah researchers introduced computer-assisted polygraph techniques in the early 1980’s, and they remain at the forefront of developments in instrumentation and analytic methods for computerized polygraph systems.
