Abstract
Mimic expression is one of the most significant variables in the process of interpersonal communication. Author of this research tries to establish if deception can be detected through deciphering mimic expressions. With the help of the newest technological equipment, we try to verify the claims about human face as emotional conduit and its usefulness in revealing deception. The high speed cameras involved and teaming up with researchers from the field of computer vision made it possible to not only study the sheer occurrence numbers of selected cues but also their dynamics. The experiments were designed in such way to gradually rise both stress level and immersion between the 3 devised experimental modules. First two of them were carried out in laboratory on a group of 120 students and the third was carried out on a group of 67 policemen in the process of initial training. The gathered data was later analyzed in interdisciplinary science team. Our data suggests there are in fact mimic expression aggregates that are connected to deception, however they can differ from person to person, general conclusion were also drawn – the team established that lie with high cognitive load projects substantially more facial cues of deception in majority of test subjects.
