The polygraph, often portrayed as a magic mind-reading machine, is still controversial among experts, who continue heated debates about its validity as a lie-detecting device. As the nation takes a fresh look at ways to enhance its security, can the polygraph be considered a useful tool? The Polygraph and Lie Detection puts the polygraph itself to the test, reviewing and analyzing data about its use in criminal investigation, employment screening, and counter-intelligence. The book looks at: The theory of how the polygraph works and evidence about how deceptivenessâ€"and other psychological conditionsâ€"affect the physiological responses that the polygraph measures. Empirical evidence on the performance of the polygraph and the success of subjects' countermeasures. The actual use of the polygraph in the arena of national security, including its role in deterring threats to security. The book addresses the difficulties of measuring polygraph accuracy, the usefulness of the technique for aiding interrogation and for deterrence, and includes potential alternativesâ€"such as voice-stress analysis and brain measurement techniques.

Detecting Concealed Information and Deception: Recent Developments assembles contributions from the world's leading experts on all aspects of concealed information detection. This reference examines an array of different methods—behavioral, verbal interview and physiological—of detecting concealed information. Chapters from leading legal authorities address how to make use of detected information for present and future legal purposes. With a theoretical and empirical foundation, the book also covers new human interviewing techniques, including the highly influential Implicit Association Test among others. - Presents research from Concealed Information Test (CIT) studies - Explores the legal implications and admissibility of the CIT - Covers EEG, event-related brain potentials (ERP) and autonomic detection measures - Reviews multiple verbal lie detection tools - Discusses ocular movements during deception and evasion - Identifies how to perceive malicious intentions - Explores personality dimensions associated with deception, including religion, age and gender

The author presents case histories of persons whose lives have been blighted by our uniquely American faith in the myth of the lie detector. Dr. Lykken also explains how to "beat" the machine, not only because it is unfair that spies and Mafia soldiers already know these techniques, but also because innocent persons have nearly a 50:50 chance of failing lie detector tests unless they use appropriate countermeasures. Many state courts in the U.S. still admit lie detector tests into evidence under certain conditions - a practice that ensures the conviction of more innocent people every year. Finally, Dr. Lykken reports on the results of recent surveys of informed scientific opinion about lie detection and presents another method of polygraphic interrogation that is designed to detect, not lies, but the presence of guilty knowledge. This method is scientifically credible and holds promise for future use in criminal investigation.

Though polygraph has been the mainstay for government and police departments since World War II, it has undergone substantial transformation in recent years. Fundamentals of Polygraph Practice bridges the gap between the outmoded practices and today's validated testing and analysis protocols. The goal of this reference is to thoroughly and concisely describe the evidence-based practices of polygraphy. Coverage will include: psychophysiology, testing techniques, data collection, data analysis, ethics, polygraph law, alternate technologies and much more. This text addresses the foundational needs of polygraph students, and is written to be useful and accessible to attorneys, forensic scientists, consumers of polygraph services, and the general public. - Includes protocols and fundamentals of polygraph practice - Covers the history of lie detection, psychophysiology, data collection, techniques and testing, data analysis and much more - Authors are internationally recognized in the polygraph field

Finding the Truth in the Courtroom combines the science behind deception and memory and their relation in court. Testimonies are oftentimes the most important piece of evidence in legal cases. Hence, this book shows how such testimonies can be riddled with deception and/or memory errors, how to detect them, and what you can against them.
