A polygraph examination is a scientific test that collects physiological data from a person with the purpose of detecting reactions associated with dishonesty.
At least three systems in the human body are recorded during a polygraph examination. Respiratory activity, motion sensor detection, and sweat gland activity. All noninvasive.
Special Note: It is important to note that a polygraph does not include the analysis of physiology associated with the voice. Instruments that claim to record voice or psychological stress are not polygraphs and have not been shown to have scientific support.
