BACKGROUND  OF  POLYGRAPH

Polygraph means "many graphs" and is descriptive of the polygraph test that measures more than one physiological change in the body, when trying to detect deception by the person being tested.  In reality, the term polygraph, as used in this detection of deception lexicon, is a misnomer.  The use of the polygraph instrument, to record human physiological change for the purpose of detecting deception, is only one of the processes and procedures used in the Psychophysiological Detection of Deception (PDD).  Forensic Psychophysiology is the discipline that provides the student, the practitioner and the researcher, with the theoretical and applied psychological, physiologice and psychophysiological fundamentals for "understanding and conducting PDD examinations and to pursue research".  (Yankee, Polygraph, Vol 23, No. 3, 1994).

The validity and reliability of a specific PDD examination (polygraph test) is a direct result of the proper administration of that specific exam.  To maximise the known potential of fear of detection of deception resulting in physiological changes insid the human body, these changes being recorded with a polygraph instrument and the proper identification of these changes by a qualified polygraphist, a comprehensive understanding of Forensic Psychophysiology and the ability to properly administer PDD exams are essential.  This understanding and ability results only from quality study and training.

In the past, training as a polygraphist usually required an extended stay in the USA.  Travelling and accommodation in USA dollar rates meant it was extremely expensive for South Africans and many others to attend these courses.  Since 1998, Veri-Dicus has presented Basic and Advanced courses in South Africa, in conjunction with the Argenbright and American International Institutes of Polygraph.

Due to the escalation of crime, fraud and corruption on the African continent, there is a growing need for highly qualified polygraphists.  This has resulted in the registration of the American International Institute of Polygraph (SA), to facilitate professional, comprehensive and internationally accredited training on the continent.
