A polygraph exam or lie detector test is based on scientific principles and are conducted by highly trained and disciplined technicians, known as Forensic Psychopysiologists or polygraph examiners.
Polygraph tests or Lie Detector tests refer to the science of the test where several physiological responses are measured at the same time to detect signs of deception. This process, called forensic psychophysiology, denotes the relationship to the mind and the body as it pertains to physical responses to thoughts and emotions.
Polygraph results are only as good as the examiner conducting the test. Hence, the American Polygraph Association (APA) has established rigorous standards to certify examiners.
Polygraph examiners are highly analytical people with excellent interpersonal communication skills. They combine knowledge of psychology and physiology to evaluate individuals for deceptive tendencies.
Polygraphers prepare reports detailing the results of their exams and submit them to their clients. Depending on the scope of questioning, the entire process can take several hours. Generally the polygraph examiner doesn’t make recommendations with regards to how to deal with the test subject but instead report their opinion regarding the veracity of the subject or the presence of deception.
Certified examiners must maintain their skills by participating in continuing education and training programs to keep up to date with their field of expertise.
It is therefore vitally important that when looking for a polygraph examiner, that you ascertain that they are properly qualified and trained through an accredited training school endorsed by the American Polygraph Association, who are the governing body for the worldwide polygraph profession.
