Ocena prawdziwości zeznań na podstawie analiz behawioralnych i wokalnych wskaźników emocji

Abstract

The assertion, if an individual is lying or telling the truth is not a simple task; one of the basic problems in this case is excess information. There are too many sources of information- words, breaks, sound of the voice, movements of the head, gestures, position of the body, breath, reddening of the skin, becoming pale, sweating, which must be analysed simultaneously. The sources can pass on information at the same time or successively, competing with one another as to which is the most important in the process of lie detection. One does not have to treat all that is heard and seen with the same precision. Not all available sources of information during hearings are trustworthy. In addition, some of them give more data than others. It is worth mentioning that most people concentrate their attention on such sources as words and mimics. People that purposely tell lies usually do not monitor, control and disguise all their behaviour. Even if they want to do so, they would probably not be able to behave absolutely in an effective way. It is difficult to imagine that someone can control every potential behaviour that involves the whole body. People like these rather conceal and fake those features, which they feel, would be most observed. They have the tendency to choose words with the highest caution. So the problems arising from the evaluation of the authenticity of the testimonies made the purposes of this paper.
