Book Description
Eighty subjects were given polygraph examinations utilizing the Guilty Knowledge Test (GKT) polygraph procedure in an effort to test the utility of this procedure in a mock crime situation. Additionally, a semi-objective numerical scoring system was implemented, modified, and evaluated. The subjects were broken down into two equal groups. The first group was programmed to commit the mock crime (a burglary/homicide). The second group did not commit the mock crime and was given no information regarding the details of the crime. Half of the sample (twenty innocent and twenty guilty), was utilized to design the scoring system. The system was then tested on the remaining half. The GKT with the modified numerical scoring system correctly identified fifteen of twenty programmed guilty subjects and seventeen of twenty programmed innocent subjects, with one inconclusive decision. The overall accuracy rate for the GKT methodology utilized in this study was 82%. (AN).

Book Description
The Handbook of Polygraph Testing examines the fundamental principles behind lie detector tests, and provides an up-to-date review of their validity. The editor presents current psychological theories, including an explanation of the cognitive processes central to polygraph testing. He describes the various methods of testing, the research in support of each method, and special issues in polygraph research. The Handbook helps readers interpret existing research studies, and learn how to improve the accuracy of polygraph testing and analysis. The dual focus on research and clinical applications makes this text appropriate for a broad range of readers, from polygraph examiners and law enforcement personnel to lawyers, scientists, and graduate students. The Handbook helps establish standards in the field by establishing a set of common terms, concepts, and processes for the people who administer and analyze the tests as well as for the researchers who test the underlying theories.

Book Description
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.

Book Description
The Guilty Knowledge polygraph test (GKT) and a variation of the test, the Guilty Actions Test (GAT), were compared in a laboratory setting. 84 men who committed or witnessed a mock crime answered "No", repeated items, or remained silent in response to items on the GKT or GAT. A monetary reward was promised for appearing innocent on the test. An interaction with scores based on skin resistance showed that innocent witnesses tested on the GKT scored more in the guilt direction than subjects in any other groups. Subjects required to say "no" were more reactive to key items than subjects in the item repetition or silence groups. Thoracic respiration scores showed a difference between guilty and innocent subjects.
