Building upon earlier prototypes, Larson devised a sophisticated apparatus that could measure and record physiological responses indicative of stress and arousal, believed to be associated with lying.
The modern polygraph machine operates on the principle that deceptive responses trigger physiological changes in the body, including alterations in breathing patterns, blood pressure, pulse rate, and perspiration levels. By monitoring these physiological parameters simultaneously, the polygraph can discern discrepancies between truthful and deceptive statements.
During a typical polygraph examination, the subject is connected to a series of sensors that monitor their physiological responses while being asked a series of control, relevant, and filler questions. The examiner analyzes the resulting data, looking for patterns or deviations that may indicate deception.
While the polygraph machine has been employed in police interrogation and investigation since 1924, its reliability and validity have been a subject of debate among psychologists and legal experts. Critics argue that physiological responses measured by the polygraph are not necessarily indicative of deception and can be influenced by factors such as anxiety, stress, or physiological conditions.
Despite its controversial nature, the polygraph continues to be utilized in various investigative contexts, albeit with caution and skepticism. Its role in criminal justice proceedings remains subject to judicial discretion, with some jurisdictions accepting polygraph evidence as admissible in court, while others remain skeptical of its reliability.
While advancements in forensic science have introduced alternative methods of deception detection, such as functional magnetic resonance imaging (fMRI) and voice stress analysis, the polygraph machine remains a fixture in the arsenal of investigative tools utilized by law enforcement agencies worldwide.
