The Psychological Detection of Deception Examination:  AKA “The Polygraph Examination or Lie Detector Test” process:

The Pre-Test Interview prepares the subject psychologically for the Polygraph Examination.

The Polygraph Examination consists of asking the subject a previewed set of questions and recording on a chart the subject’s physiological responses to the questions. Normally, a minimum of three charts are obtained.

Using the questions and charts, the Polygraph Examiner diagnoses the presence of physiological responses to reach a conclusion concerning the issue being tested.

Statements by the subject can be rapidly and accurately verified or discredited. The length of Examination is 2 1/2hrs approx. Many countries around the world conduct Polygraph Examinations on a regular basis. Testing activity in North America has expanded very rapidly and Canada is also following this trend. This will mean increased screening requirements for many sectors of government, civil servants and professionals.
