The Polygraph Test is commonly known as a “lie detector test.” It is a procedure that detects several physiological indicators, including pulse, blood pressure, respiration, and skin conductivity, which indicate if a person is being untruthful when asked a series of questions. The principle behind the polygraph test is that any untruthful responses produce different physiological responses than those associated with non-deceptive answers.
