Polygraph: Legal Insights into Deception Detection and Admissibility
Definition & Meaning
A polygraph is a device used to assess physiological responses in individuals to determine if they are being truthful or deceptive. The process typically involves measuring factors such as heart rate, blood pressure, and respiration while the individual answers questions. A person who administers polygraph tests is known as a polygraph examiner. Due to varying state regulations, many jurisdictions require these examiners to be licensed.
