What is a Polygraph Test?

In order to determine whether someone is lying about a particular incident, a polygraph or lie detector test examines the physiological processes taking place in the body while they are answering certain questions. A competent polygraph examiner will record the physiological response data of the person being questioned. The charts are then analysed, and based on the analysis, a scientific scoring procedure is used to determine the subject’s truthfulness. We offer lie detector test services for every conceivable circumstance.

How do Lie Detection Tests Work?

Four to six sensors are attached to a subject during a polygraph test. A polygraph is a device that records numerous (“poly”) impulses from the sensors on a single strip of paper or computer. Generally, the following parameters are recorded:

  • Breath rate and depth
  • Heart rate
  • Blood pressure
  • And perspiration

Some newer polygraph machines will also measure eye movement and dilation.

To establish a baseline for the subject before the polygraph test even begins, the examiner poses three or four short questions. Once a baseline has been established the examiner will proceed with the actual test questions. All of the subject’s indicators are then recorded on paper or a computer.

The examiner will look at the result while questioning the subject and adjust the questions accordingly. Once the examiner has asked all the questions he or she felt necessary to obtain an accurate result he or she will stop the exam.

After completion of the test, the examiner will look at the indicators for any big changes(such as a faster heart rate, higher blood pressure, and increased perspiration) that will typically indicate that the person is lying.
