Essentials of Polygraph and Polygraph Testing

Throughout history, there has been an intrinsic need for humans to detect deception in other humans. Developed in 1923, the polygraph machine was a tool designed to do just this. To date, there have been many improvements made to the basic polygraph instrument. This book outlines the instrumentation as well as the latest in questioning techniques and methods available to the professional interviewer to determine truth from deception. The book covers psychology and physiology, a history of polygraph with the advances of leading figures, question formulation, data analysis, legal implications and legal cases, and the author’s developed technique Integrated Zone Comparison Technique (IZCT).
