Our Polygraph Services
Secure Polygraph Solutions is dedicated to the truth and uses polygraph testing also known as lie detector techniques in finding truthful answers. While the subject is being interrogated and answers a series of unique questions, the polygraph measures and records several physiological keys, such as relative changes in blood volume, thoracic and abdominal breathing patterns as well as skin conductivity.
Testing and reporting structures are streamlined, in place and strictly adhered to, to ensure confidentiality and respect, as well as professionalism at all times. The American Polygraph Association (APA) believes that scientific evidence supports the validity of polygraph examinations that are conducted and interpreted in compliance with documented and validated procedures. Therefore, such examinations have great probative value and utility for a variety of uses.
Our Examiners / Tracers:
Director, Tersia Fritz is our forensic psychophysiologist and was trained in 2007 at the American International Institute of Polygraph. In 2008 she did an advanced course with the Academy for Scientific Investigative Training (Forensic Assessment Interview and Integrated Interrogation Techniques), and she is a member of the Polygraph Association of South Africa (PASA) and the American Polygraph Association (APA).
Johan Van Niekerk, our forensic psychophysiologist, served in the South African Police Service from 1989 to 2006 where he was exposed to an immense amount of training, and gained a lot of experience by being part of the police’s detective branch where he worked himself up to a criminalistics expert (Fingerprints and Identikit Specialist). Johan was trained in 2007 at the Academy for Scientific Investigative Training (Forensic Assessment Interview and Integrated Interrogation Techniques) and attended several advanced polygraph seminars. He is a member of the South African Polygraph Federation (SAPFED).
Please note that we do not conduct Voice Stress Analysis (VSA), which is said to record psychophysiological stress responses that are present in the human voice. It has been said that it is not possible to cleanly separate the voice signals into components, due to emotion and deception. The technique’s accuracy remains debated. There are no independent research studies that support the use of VSA as reliable lie detection technology, while there are numerous studies that dispute its reliability.
