Lie detector (polygraph)


Lie detector (polygraph) is a device recording and evaluating response of human body to external stimulus. For example, a person reacts to a sharp sound not only externally - by turning his/her head toward its source, but also on internal level - by changing of heart and respiratory rate and other biological parameters. Moreover, this reaction is spontaneous and cannot be controlled by the person. The same thing happens during an interview with a polygraph (lie detector). The subject is asked and answers a series of questions according to a certain technique. When the person responds, deceptive answers cause certain reaction of the respondentís body and are registered by polygraph. Itís impossible to hide these reactions, as such changes in body functions are not easily controlled by the conscious mind.

Polygraph test usually lasts from 40 minutes to 2 hours. Polygraph examiner explains how to behave and what to say during the interview and then places sensors on the subjectís body. Lie detector test is absolutely safe and painless procedure. Results of the test become clear almost immediately after the interview or, more rarely, several hours afterwards.

Typical testing on lie detector consists of three major stages: it starts with a pre-test interview when polygraph examiner explains to the subject testing procedure and gains some preliminary information about the subject and his/her health condition. Second stage is the actual test, when the subject answers the questions of polygraph examiner. Third stage is post-test interview, when examiner clarifies why the subject gave certain answers to the questions.
