There have been several important studies on fear, heart actions, respiration etc which contributed to the development of polygraph test as part of criminal investigations. Significantly, human beings have always tried to develop techniques to detect lie and determine truth, as it is common to them to deceive each other. Interviews and interrogations are part of such techniques to find deception and new techniques of lie detection emerged in the course of time. “In the 20th century, lie detection took on scientific aspects with the development of techniques that use measures of physiological responses as indicators of deception. The best known of these is the polygraph. This technique, which relies on physiological measurements developed early in the century, has become for many in the U.S. law enforcement and intelligence communities (including counterintelligence officials in the several agencies…) the valued method for identifying criminals, spies, and saboteurs when direct evidence is lacking.” Therefore, it is essential to comprehend that the polygraph test method for lie detection has acquired general acceptance over a short period of time and it has become one of the most defining techniques of determining the truthfulness of a matter. ...

The bias and the accuracy of the significance tests are provided below for each observation value. a. 10 observations The following is the results obtained for the Ordinary least squares regression performed on the dependent variable ‘y’ for 10 observations. From the above results, the bias for the YSeries is -0.331 and has a very low standard deviation of 0.008. The RMSE (Root Mean Square Error) is an absolute measure of the residuals. A low value indicates a better fit. The RMSE is relatively higher for the Intercept in comparison to the RMSE values for the XSeries and YSeries, suggesting that the latter two parameters exhibit a better absolute fit to the given data. The EDFs from the analysis is shown below: Based on...

Analysis of Polygraph
...Analysis of Polygraph Basically, a polygraph measures and records physiological activities simultaneously through use of some conventional instruments. These instruments are mainly focused on measuring physiological activities such as respiratory activities, sweat gland activity, and cardiovascular activities among others. This implies that contrary to the belief of many, polygraphs do not use physiological activities associated with the voice. Nonetheless, the foundations of a polygraph test are based on the belief of varying physiological responses when an individual is lying and when telling the truth. As such, polygraphs are used in...
