How a professional polygraph works
A professional polygraph is an instrument that simultaneously records several physiological signals from the human body. These signals are related to emotions and thus to whether a person is lying or telling the truth. Some of the signals that a polygraph measures are:
The heart is one of the most emotionally sensitive parts of the body. During a polygraph test, heart rate is measured to identify changes in heart rate, which can indicate whether a person is experiencing stress or anxiety when answering questions.
Breathing can also be affected by emotions. A polygraph measures both the rate and depth of breathing. If a person is nervous or stressed, their breathing rate is likely to change.
Sweat is another manifestation of emotions. The polygraph test measures skin conductance, which is directly related to the amount of sweat produced. If a person is lying, he or she is likely to sweat more than usual.
