Book Description
This project was designed to provide information on the usefulness of polygraph techniques in detecting truth and deception in criminal investigations. The report describes the methodology of each of the eight experiments and studies conducted. In addition to studies involving criminal suspects in a field situation, other studies involved laboratory experiments with a mock-crime paradigm. The lab experiments investigated aspects of the general problems of accuracy and reliability not easily studied in the field situation. They also assessed the usefulness of a number of physiological measures that had received little attention in previous scientific research. Studies also were undertaken to evaluate the commonly-held belief that psychopaths can beat the polygraph, the adequacy of current practices used by field polygraphists, the usefulness of different question structures in polygraph examinations, and the risks of different types of errors in field applications. The project results indicate that polygraph examinations using control-question or guilty-knowledge tests are highly accurate.

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
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

Book Description
Deception is a ubiquitous phenomenon in social interactions and has attracted a significant amount of research during the last decades. The majority of studies in this field focused on how deception modulates behavioral, autonomic, and brain responses and whether these changes can be used to validly identify lies. Especially the latter question, which historically gave rise to the development of psychophysiological “lie detection” techniques, has been driving research on deception and its detection until today. The detection of deception and concealed information in forensic examinations currently constitutes one of the most frequent applications of psychophysiological methods in the field. With the increasing use of such methods, the techniques for detecting deception have been controversially discussed in the scientific community. It has been proposed to shift from the original idea of detecting deception per se to a more indirect approach that allows for determining whether a suspect has specific knowledge of crime-related details. This so-called Concealed Information Test is strongly linked to basic psychological concepts concerning memory, attention, orienting, and response monitoring. Although research in this field has intensified with the advancement of neuroimaging techniques such as PET and fMRI in the last decade, basic questions on the psychological mechanisms underlying modulatory effects of deception and information concealment on behavioral, autonomic, and brain responses are still poorly understood. This Research Topic brings together contributions from researchers in experimental psychology, psychophysiology, and neuroscience focusing on the understanding of the broad concept of deception including the detection of concealed information, with respect to basic research questions as well as applied issues. This Research Topic is mainly composed of originalresearch articles but reviews and papers elaborating on novel methodological approaches have also been included. Experimental methods include, but are not limited to, behavioral, autonomic, electroencephalographic or brain imaging techniques that allow for revealing relevant facets of deception on a multimodal level. While this Research Topic primarily includes laboratory work, relevant issues for the field use of such methods are also discussed.

Book Description
Traditional techniques for detecting deception, such as the 'lie-detector test' (or polygraph), are based upon the idea that lying is associated with stress. However, it is possible that people telling the truth will experience stress, whereas not all liars will. Because of this, the validity of such methods is questionable. As an alternative, a knowledge-based approach known as the 'Concealed Information Test' has been developed which investigates whether the examinee recognizes secret information - for example a crime suspect recognizing critical crime details that only the culprit could know. The Concealed Information Test has been supported by decades of research, and is used widely in Japan. This is the first book to focus on this exciting approach and will be of interest to law enforcement agencies and academics and professionals in psychology, criminology, policing and law.

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.

Book Description
"Polygraphy;' "lie detection;' and the "detection of deception" are all terms that refer to an application of the science of psychophysiology, which itself employs physiological measures to study and differentiate between psychological processes. The issues raised by polygraphy are controversial. One such issue is whether the polygraph is a genuinely scientifically based application, or merely a purported application, of psychophysiology. Such concerns are of interest not only to polygraph practitioners and to specialists in psychophysiology, but also to such other specialists as those in the legal and forensic professions. Moreover, there are two sorts of nonspecialists who should also be concerned. On the one hand, there are the potential "users" of the polygraph-for example, a manager who employs a polygrapher to check on subordinates; on the other hand, there are those "used by" the polygraph - the employee who is subjected to the poly graphic examination. To begin with the user of the polygraph, this person should know not only about its overall accuracy, but also about the rationales of the various detection methods and their validity for different purposes in different sorts of situations. This infor mation is important, because even for the potential user there are costs as well as benefits. Aside from the lack of trust generated by the polygraph, there have also been successful suits by employees against employers, so there are traps in polygraph usage that employers (and managers) need to keep in mind.
