What is the polygraph?

The polygraph (lie detector) is a scientific instrument capable of simultaneously recording changes in several physiological variables such as blood pressure, pulse rate, respiration, electrodermal activity, and others, while the subject is asked a series of questions pertaining to a specific issue under investigation. The charts (polygrams) generated during the polygraph examination are interpreted by a polygraph examiner.
