Detecting Deception: The Benefit of Looking at a Combination of Behavioral, Auditory and Speech Content Related Cues in a Systematic Manner

People communicate with each other across distance in a variety of ways, for example, via the telephone, via electronic forms of communication (the written word) or via videolinks. In this article, behavioral, auditory and speech content related cues which research has shown discriminate (to some extent) between liars and truth tellers will be discussed. Although research has indicated that people are generally poor at detecting deceit, some recent studies suggest that looking at nonverbal, auditory and speech content related responses in an objective and systematic manner will lead to more accurate classifications of liars and truth tellers. These studies will be discussed. Apart from examining the available cues objectively and systematically, lie detection might further improve if the lie detector employs certain communication techniques. In the final part of this article we will discuss some of these techniques.
