A polygraph instrument is a diagnostic device used during a polygraph examination. It monitors and records physiological responses, including respiratory, electrodermal, and cardiovascular activity, in reaction to verbal or visual stimuli. This information helps assess truthfulness or deception during questioning.
Polygraph instruments are often used in various legal contexts, particularly in criminal investigations and employment screenings. In criminal cases, they may assist law enforcement in evaluating the credibility of witnesses or suspects. In employment situations, especially for positions involving security clearance, polygraph tests may be utilized to screen candidates.
