This paper reports on an experiment exploring the relationships between Non-Verbal Communication and the act of lying and telling the truth. Lying has become a social competence, that for example enables one to 'keep face' during embarrassing situations or to manipulate others to obtain personal gains.
This aptitude is dependent on several variables; some are based on the spoken language. However, the most important ones are based on the control and use of body language and more specifically facial movements. Fourteen participants took part in an experiment in order to demonstrate a relationship between the insecurity that exists when telling a lie and the act of constructing a reality. It was found that the participants blinked more frequently when they were lying.
However, large differences were observed between the different participants. In addition, the participants had a significant tendency to believe the other participant was lying to them, and felt a considerable discomfort when lying or being lied to. It was also found that some of the participants invented situations and scenarios of their own accord during the experiment.
