Exploring the Legal Definition of a Polygraph Test
Definition & Meaning
A polygraph test, commonly known as a lie detector test, is a procedure that measures physiological responses to questions posed by an examiner. The polygraph instrument records various bodily functions, such as heart rate, blood pressure, and respiration, to determine whether a person is being truthful or deceptive. This examination is often used in criminal investigations, employment screenings, and security clearances.
