| dc.description.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. | pl_PL |
