The Effectiveness of fMRI Data when Combined with Polygraph Data

Abstract

The Integrated Zone Comparison Technique (IZCT) was utilized with computerized polygraph instrumentation and the Academy for Scientific Investigative Training’s Horizontal Scoring System ASIT PolySuite algorithm, as part of a blind study in the detection of deception. This paper represents a synergy analysis of combining fMRI only deception data with each of the three individual physiological parameters that are used in polygraph. They include the electro-dermal response (EDR), pneumo, and cardio measurements. In addition, we compared the detection accuracy analysis using each single parameter by itself. The fMRI score and each individual polygraph parameter score on individual subjects were averaged to establish an overall score.

Redefining the Road for the Industry

Abstract

The polygraph is an instrument that detects, monitors, and records physiological responses that are allegedly of psychological origin and attributed to deception. Hence the human mind and its complex psychology are the core of the detected physical responses. However, the polygraph industry has almost entirely overlooked psychological issues in its training and publishing. The industry focuses its attention and interest on various technical aspects of the test such as e.g. scoring, rather than concentrating on what is most important, i.e. the examinee’s psychology, as it is responsible for almost the entire test result. The paper extensively explains the importance of examinee psychology and its influence on test outcome, points to the shortfalls in training and publication activity of the industry, and discusses the result and impact of the industry’s approach.
