Since the establishment of the polyphysiological device by John Larson in 1921, the polygraph has been repeatedly advanced. The modern lie detector allows for psychophysiological study, through which is fixed the modification of multiple physiological parameters such as sweat intensity, blood pressure, breathing frequency, heartbeat and others.
Polygraph from the Greek words poly – many, graph - write, often called "plethysmograph", "variograph," "lie detector" is introduced for the first time in terminology by John Larson, but for lie verification is spoken yet in the primitive social order. The need for lie detecting has emerged since the very moment when people started to come together in groups. Historically, it is known that the various peoples have drawn a variety of special techniques and rituals to recognize lies and expose a liar. Even in those distant times it was observed that people who committed crimes, because of fear of being found, one unwittingly gets different changes in their physiological functions. In ancient China, for example, the suspected in a crime was given dry rice in their mouth. It was believed that if the rice remains dry after hearing the prosecution (from the fear of being exposed a person frequently has a dry mouth) the suspected guilt is proven.
The modern polygraph is a device fixing more than 10 psychophysical parameters. The functioning of the device has been proven through the special "psycho-physiological fenomeen." At its base lies the ability of the human body to respond to external stimuli that carry a proven situationally important information.
The modern polygraph with its proven precision serves as a lie detector, as in many countries polygraph study forms a key part in revealing serious crimes and proving them in court.
