Nowadays, the cases of intentional mental and behavioral counteraction by examinee’s, while conducting a psychophysiological detection of deception using computer polygraph (herein after – “PDD”) growing more frequently.
In practice, these polygraph countermeasures are used both by current employees of companies and by applicants for positions and of course in the field of intelligence.
Eye tracking is a technology that allows tracking and analyzing the movement of a person’s eyes. Based on oculography methods, this approach is used to study how people perceive information, interact with their environment, and make decisions.
The eye tracking method involves the use of specialized cameras and sensors that record eye movements. These devices can determine exactly where a person is looking by capturing their gaze on specific objects or areas of the screen. Data is collected and analyzed using software, allowing me as a researcher to obtain information about which elements attract attention, how much time an asset spends on each of them, and the sequence of their gaze. The method of oculography in my psychophysiological researches helps to identify patterns in human behavior and reactions to stimuli.
Eye trackers use infrared light sources directed at the eyes and cameras that capture the reflection to determine the direction of the gaze. This allows for the creation of heat maps and gaze movement lines, which show which elements users focus on.
It is important to note that these signs are not absolute indicators of lying, and their interpretation requires a comprehensive analysis in combination with other methods and the context of the situation. Eyetracking is just one of the tools that can be used in such scientifically approaches.
The results of researches using eyetracking can be quite diverse. For example, in the field of lie detection, the eye tracking method allows for the identification of discrepancies between verbal and non-verbal signals. Research, my as well, shows that when attempting to deceive, a person may exhibit certain behavioral patterns, such as avoiding eye contact or frequent blinking. Thus, eye tracking is a powerful tool for a deep understanding of human behavior and making more informed decisions in various fields.

Classic polygraph registers electrodermal, cardiovascular and respiration reactions, so psychophysiological changes, which demonstrate strong emotional response while answering to test questions. VERUM measures changes in pupil size and eye movement dynamics, which reflect the brain’s mental efforts as a person reads and answers questions.
The “ODT” is based on the assumption that lying is cognitively more demanding that telling the truth. The recruitment of mental resources to accomplish additional cognitive and meta-cognitive activities could account for the observed impact on pupil dilation, eye movements, response time and error rates. However, the data suggest that guilty participants invest more mental effort in answering relevant statements quickly and accurately in attempt to avoid detection. VERUM can be used both independently and in conjunction with a classic polygraph and is an ideal tool for improving accuracy, objective control and building a coherent barrier.
According to polygraph examiners, who already use “ODT” in pre-employment screening of huge number of workers or job candidates, it is better firstly to use VERUM, and then, according to the obtained data, use a classic polygraph to test a deceptive person. It gives a faster and more accurate result; the percentage of errors is reduced to zero.
Have you ever wondered why there are such phrases as “He has shifty eyes”, “She has inviting eyes”. Chances are that these phrases are referring to the size of a person’s pupils and their gaze (fixed look). Your pupils not only respond to light and dark but also your moods. A person who is excited and positive will have dilated (enlarged) pupils, sometimes up to four times their normal size. Conversely, angry and negative moods cause the pupils to constrict.
Retired police lieutenant colonel. In 2007, I received a degree of mathematician from the St. Petersburg State Electrotechnical University "LETI", specializing in computer security; and in 2012 - a law degree from St. Petersburg University of the Ministry of Internal Affairs of Russia, specializing in law enforcement. I am fluent in English, can read and translate Spanish.
Besides, I received training as a polygraph examiner at the National School of Lie Detection and participated in the ISOPE international conference of polygraph examiners. I worked at the Bureau of Special Technical Events under the Main Directorate of the Ministry of Internal Affairs of Russia for St. Petersburg and Leningrad Region.
I have a total experience of over 2000 psychophysiological examinations with a polygraph for law enforcement agencies and commercial companies. Since 2020 I have been working as an independent polygraph specialist.
