" Subjects are told to think of specific incidents of lies or mistakes when answering these questions "no" to deliberately provoke a reaction to a lie.
deceptiveness, use of countermeasures and the outcomes of a polygraph examination. Stigmas may be easily visible e. Indeed, as already noted, it is rarely clear exactly what polygraph tests are designed to measure, or how the various pieces of data obtained from polygraph tests are thought to be linked to states or attributes of the examinee, making it difficult to even initiate the process of construct validation Fiedler et al. A similar advantage is not conferred by a variant of the CQT that is gaining more widespread use: the directed lie test DLT.
Contrary to the notion that sympathetic nervous activation is global and diffuse, highly specific regional sympathetic activation has been observed in response to stressors Johnson and Anderson, 1990even in extreme conditions such as panic attacks Wilkinson et al.
Unfortunately, field studies of the CQT are based on the outcomes of adversarial tests. A variation of Theories and applications in the detection of deception theory holds that the stimuli associated with a major transgression serve as conditioned stimuli while the act itself e. Department of Energy DOE and some other federal agencies U. 1013 did not support work on validity issues in forensic science because under Frye, courts accepted the judgment of communities of presumed experts.
We are more impressed with the similarities among polygraph testing techniques than with the differences, although some of the differences are important, as we note at appropriate places in this and the following chapters. For example, the percentage of correct responses is often conceptualized as reflecting sensitivity, but it changes when bias changes.
Human Factors: The Journal of the Human Factors and Ergonomics Society.
Journal of Applied Psychology, 70, 177-187. Basic polygraph research should consider the latest research from the fields of psychology, physiology, psychiatry, neuroscience, and medicine; comparison among question techniques; and measures of physiological research.
Lynn 1966 has summarized the physiological profile of an orienting response as decreased heart rate, increased sensitivity of the sense organs, increased skin conductance, general muscle tonus but a decrease in irrelevant muscle activitypupil dilation, vasoconstriction in the limbs and possibly vasodilation in the head, and more asynchronous, low-voltage electrical activity in the brain.
Such a response on one question would not engender much confidence in the interpretation that the person had concealed knowledge of the true amount.
Examiners are instructed to create emotional conditions designed to lead to differential levels of arousal and physiological responsiveness in innocent and guilty examinees.
His work has appeared in outlets such as the Proceedings of the National Academy of Sciences, Journal of Communication, Communication Research, and Journal of Language and Social Psychology.
