American & British Polygraph Testing Associations Members

A polygraph test is commonly referred to as a lie detector test. A polygraph is a machine in which the multiple (“poly”) signals from the sensors are recorded (“graph”).
Studies have evidenced that deceptive answers will produce physiological responses that can be differentiated from those associated with non-deceptive answers. The polygraph is one of several devices used for lie detection as an interrogation tool with criminal suspects or candidates for sensitive public or private sector employment.

The Polygraph measures and records several physiological indices such as pulse, blood pressure, respiration and skin conductivity while the subject is asked a series of control questions and specific questions. The examiner will converse with you and jointly devise specific questions to be asked prior to the test taking place.

The subject of the Lie Detector Test or Polygraph Test will be attached to the Polygraph via;

  • A cuff around their arm, similar to the cuffs used to monitor blood pressure.
  • 2 monitors across the chest and abdominal region over clothing.
  • 2 electromagnetic finger monitors.
  • A cushion that is sat on to monitor movement.

  • Do you have a mortgage with HSBC?
  • Are you sat down?
