How does a polygraph test work?

Typically speaking, people hooked up to a polygraph machine will have around 4 to 8 sensors placed on various parts of their body. These sensors work to determine slight changes in the subject's breathing, heartbeat, blood pressure, pulse and perspiration. Once the examiner is happy with how everything is set up the test can commence. It is also important when utilising polygraph services to make sure that you work with an experienced provider.

The test

In order to ascertain how the person being tested reacts to certain inquiries they will be asked a series of everyday questions which do not pertain to the actual test. Once this is out of the way the session can begin. The sensors pick up on minute differences in breathing, perspiration, blood pressure and heartbeat. These fluctuations will then be recorded on a piece of paper for further examination.The entire session will usually be recorded by the polygraph examiner so that he or she can revisit it for analyses.
