Polygraph test, also known as the lie detector and deception detector, is a unique technology that measures the physiological responses of a person while he is being questioned to determine the facts. We have often seen the use of this instrument in movies and crime dramas, and sometimes in a funny way. However, it is a serious job and requires a skilled professional to carry out the test and understand the results accurately. The tool measures the three main signals of involuntary arousal - respiration, blood pressure and skin conductivity.
A plethora of questioning methods are employed to conduct the polygraph test. The most commonly used technique in criminal cases is Control Question Test (CQT). It analyzes the responses of the accused by comparing the relevant questions with the control questions. The control questions are made in such a manner so as to control the effect of the baleful nature of the pertinent questions. The control questions are related to actions that are akin to the ones being investigated, however they refer to the past of the one being questioned and are more broader in perspective. More pronounced physiological responses to relevant questions than the control questions result in concluding deception. On the other hand, greater response to control questions proves non-deception. If there is no significant difference between the responses of relevant and control questions, then the result is termed inconclusive.
This is the way polygraph testing is conducted in Atlanta or any other place in the world to determine the truth and find the guilty.
