Police Polygraph Training

Police use polygraphs to detect lies.

The truth. Those at the American Association of Police Polygraphists believe that the difference between truth and deception parallels the difference between right and wrong. Police officers trained in polygraph testing help support this cause.

  1. Purpose

    • Polygraph training helps police in their investigations. The technical term "psychophysiological detection of deception," or PDD, refers to the process that helps officers detect pulse rate, blood pressure, respiration and perspiration with the use of a polygraph machine.

    Details

    • An officer interested in polygraph training typically must first take a polygraph test herself, notes "Careers in Focus: Law." This helps determine if she has the moral character for administering these tests to others. Trainees learn how to operate the polygraph machine, ask appropriate questions and interpret polygraph charts.

    Schools

    • The American Association of Police Polygraphists accredits schools specifically for training those performing police and investigative work. For example, the Academy for Scientific Investigative Training offers training for three main techniques: the forensic assessment interview technique, integrated interrogation technique and Morgan interview thematic technique.
