Forensic psychophysiology is based on the principle that an individual’s fear of detection of deception causes physiological changes. These changes are recorded and evaluated by a qualified Forensic Psycho- Physiologist and the result made known to the examinee and client. We ensure that each innocent examinee has the opportunity to be regarded as such and every deceptive element exposed.

The techniques utilized and interview methodology applied allows us to clearly differentiate between Innocent and Being Deceptive about the issue on hand. We have several precautions in place both internally and externally to ensure that the result we provide is accurate and has been validated.

How does it work?
A Misconception about polygraph does exist among certain individuals, which needs to be addressed.

It is important to understand what a polygraph examination entails:

  • A polygraph instrument will collect physiological data from at least 3 systems in the human body.
  • A typical polygraph examination will include:
    1. A period referred to as a pre-test
    2. A chart collection phase
    3. A test data analysis phase

In the pre-test, the polygraph examiner will complete required paperwork and talk with the examinee about the test. During this period, the examiner will discuss the questions to be asked and familiarize the examinee with the testing procedure.

During the chart collection phase, the examiner will administer and collect a number of polygraph charts.

Following this, the examiner will analyze the charts and render an opinion as to the truthfulness of the person taking the test.

Periodic/Screening Examinations
Periodic polygraph examinations is used as a preventative measure. It reduces theft and fraud by identifying compromised individuals during periodic screening. This is effective in industries with large volumes of stock. Having regular examinations in such a setting, offers a psychological shield against theft, as employees know they will be subjected to routine testing, say every 6 months or period you require for testing . Staff would also then be less likely to fall victim to criminal syndicates looking for a soft target. Companies are enforcing the practice of doing routine polygraph tests periodically within the company.

Specific Polygraph Examinations
This type of Polygraph Examination is a case/issue specific examination, that is aimed at identifying the deceptive party and clearing the innocent.

This can be used in any type of scenario where the aim is to determine the involvement of individuals in a specific incident like, Theft, Fraud, use of drugs and sex offences like infidelity.
