"The Quadri-Track Zone Comparison Technique is a psychological test that infers deception or truthfulness to the target issue by the elimination of variables identified in Chapter 9, Forensic Psychophysiology Using the Polygraph (Matte 1996) that could have caused the autonomic responses other than a deliberate attempt at deception. These variables fall into four categories: (a) Emotionally induced sympathetic response, (b) Non-Emotionally induced sympathetic response, (c) Emotionally induced parasympathetic response, and (d) Factors affecting strength of emotional and non-emotional response."(...)
