The future of lie detection technology has arrived in South Africa. The Converus EyeDetect is an incredible Detection of Deception instrument that is easy to implement, more cost effective than traditional polygraph examinations and less invasive. Despite all of this, it still boasts an incredible accuracy rating of 86%. Due to the fact that it is a less expensive and and easy to implement, the EyeDetect system is the perfect tool for large scale integrity assessment or pre-employment screenings. Combined with a traditional polygraph examination in a successive hurdles approach it becomes the most powerful and accurate lie detection screening tool in existence.
Features & Benefits
There are no sensors attached to the participant as the instrument only measures certain physiological changes that occur within the eye. The process is mostly automated and all the questions on the test are answered privately by the participant with simple 'Yes' or 'No' statements.
SIMPLE TO USE
The Converus EyeDetect system is easy to set up, simple to implement and simple to complete. Due to the process being automated the participants only need to follow a few onscreen instructions, and are given a practice test to get used to the process.
The test is cheaper to implement than standard polygraph testing and has less limitations, which is perfect for large scale screenings or pre-employment programs. Alternatively, your company can purchase an instrument, which will include training and support from the PISA Integrity Assessment Centre, which significantly reduces the implementation cost as only a license fee is required.
The Converus EyeDetect system has a scientifically validate accuracy of 86%, making it one of the most accurate detection of deception technologies in the world.
How Does EyeDetect Work?
The brain and eyes respond to deception. The greater the consequences of the lie, the greater the cognitive load. This affects the eyes. EyeDetect measures changes in pupil diameter, eye movement, reading behavior, blinks, fixations and other things.
Using an infrared camera and complex algorithm, a person’s credibility score is calculated: truthful or deceptive.
Participants answer True/False questions on a computer. The infrared camera records eye behaviors.
When the test concludes, responses to questions and eye measurements are uploaded to a web server for immediate scoring.
Those authorized can view results in the web-based Converus Dashboard. A Converus Credibility Score shows the probability the person was truthful.
What Does EyeDetect Measure to Determine Deception?
While reading a computer-based series of questions, EyeDetect measures an examinee’s response accuracy, response time, pupil diameter, reading behavior and blink rates. The results are consistent with the cognitive workload hypothesis.
- Guilty individuals — when compared to innocent individuals and while responding to simple test statements — make more errors, take longer to respond, make more fixations on the text, have longer reading times, and have longer rereading times.
- Guilty individuals blink significantly less often as they process statements answered deceptively versus answered truthfully.
- Guilty participants show greater increases in pupil diameter for statements answered deceptively than for statements answered truthfully.
- Guilty participants respond faster, make fewer fixations, and spend less time reading and reading statements about the crime they committed than statements about another crime or neutral statements.
Simply put, an increase in the cognitive load is associated with recalling a task and used to distinguish between deceptive and non-¬deceptive responses. This is more pronounced when deceptive individuals respond to complex statements. It takes motivation and effort to deceive.
Each test consists of an introduction, a practice test, and then five sessions of 48 true or false statements about relevant issues and neutral questions, as well as four sessions of alpha-arithemetic questions . The questions are repeated in a randomized order. The five relevant/neutral question sessions are separated by the four sessions with alpha arithmetic questions.
Corporate & Enterprise Lie Detection: Create a Culture of Integrity
International studies indicated that corruption adds up to 10% to the cost of doing business and up to 25% to the cost of procurement contracts in developing countries. Considering the high crime-rate in South Africa, it the impact of such unethical and illegal activities are far worse, and the implications can be devastating to the company, the customer and the employee. This is why integrity management should be such a high priority in any business.
For human resources managers and leaders, the Converus EyeDetect system is the ideal tool for large scale integrity management programs, and with the assistance of the PISA Integrity Assessment Centre can be implemented easily, effectively and without breaking the budget. Never before has it been so simple to instill a culture of integrity in the workplace.
For security companies the Converus EyeDetect system is the ultimate means of ensuring that security officers do not become compromised. Due to the low cost of implementation the system can be used for continuous nationwide screening. With the assistance of the PISA Integrity Assessment Centre your security company can deploy their own EyeDetect instruments nationwide with their own trained employees. Due to the test itself being an automated process, it means that the results can not be tampered with or influenced with personal bias or threats, making the ultimate in uncompromising integrity management solutions.
