A lie detector test or more commonly known as a polygraph test is used to record the differentiation in the physiological state of a human being while answering structured questions. Physiological indices like respiration, pulse and blood pressure are recorded through a lie detector and analysed during a question-answer session. A lie is detected as soon as the physiological responses deviate from the normal responses the test subject gave.
The use of polygraph (Lie Detector) has expanded over the years from the public to private investigations. Not only has it been portrayed as a cultural icon in advertisements and crime dramas, the polygraph is widely recognized by masses all around. The idea of recognizing deception through a machine has inspired millions to find the veracity in critical situations. Resolving matters like cheating partners, fraud and reasonable crime suspicions has been accredited to a lie detector many times.
Even though many psychologists have developed significant controversies towards the authentication of a polygraph test, the demand for lie detection is still quite overwhelming. This lie detector test consists of a test subject and an examiner/analyst who records and analyses data from the lie detector. Contrary to early age practices, modern technology is used to record the psychophysiological changes in the present time. However, there has been diminutive development in the questionnaire structure asked from the test subject.
In a standard situation, the test subject is asked questions in the pattern of a Control Question Test (CQT) where responses to relevant questions are compared to the “control” questions. The relevant questions are directed towards the main issue and the control questions concern a broader aspect of the investigated offence. If greater responses to relevant questions are recorded against control questions, deception is established. An inconclusive test result may occur when no difference in responses is recorded.
After years of experience in collecting polygraph data from people with different backgrounds, mind-set, habits and experiences have enabled examiners to develop their lie detection techniques. Young lie detection analysts have limited expertise to offer as compared to experienced examiners who can verify responses of different test subjects according to their developed verdicts. Spending time in understanding dissimilar responses of various people is essential to institute the notion that standard responses may not apply to all individuals. Lie detection has heavily relied on systematic psychological functioning and has failed to develop on how deceptions differ person to person.
