The “truth-bias,” the expectation that, normally, one tells the truth, is proposed to be the cornerstone of humanity (Bok 1978). Yet, it is the skill of displacement – speaking of things which are not present – and thus also the ability to deceive that is the basis of human language (Aitchison 1996). A society of

Much research attention has been devoted to identifying the factors that affect people’s ability to detect others’ deceptive acts. Communication researchers typically have focused on the accuracy of judgments based on the verbal and nonverbal behaviors of a message source, unaided by technological devices or extra-interaction information. In general, results show that people are not
Wizards of deception detection are rare individuals who achieve scores of 80% or higher on at least two of three videotaped lie detection tests. Most people’s accuracy on these tests is about 50%, as would be expected by chance alone. Of more than 15,000 people tested, only 47 have been so classified. Although these individuals
Deception is defined, for the purposes of this research paper, as a successful or unsuccessful deliberate attempt to create in another a belief that the sender of the message considers to be untrue. Although it is hard to think of a context in which no deception transpires, the study of deception and how to detect
The credibility and reliability of children’s testimony are particularly important in instances where children are called on as primary witnesses in legal proceedings, such as sexual abuse or child custody cases. Although it is expected for children to provide truthful statements about given events, children may also give false reports in these situations for a
High-stakes lies occur where there are large positive consequences of getting away with the lie or large negative consequences of getting caught. Because the outcome of the lie is of considerable concern to the liar, it follows that he or she will probably experience more guilt and/or detection anxiety than when telling low-stakes lies. In
Cognitive load interview protocols are designed to make interviews more demanding for suspects. This increased demand has a greater effect on liars than on truth tellers because liars already find being interviewed more mentally taxing than do truth tellers. The result is that cognitive load interview protocols facilitate discrimination between liars and truth tellers. Lying
P300 is a brain wave derived from the electroencephalogram (EEG), which has recently been used as a novel information channel in the detection of deception. The traditional channels are recorded from the autonomic nervous system and include physiological activity such as respiration pattern, blood pressure, and skin conductance. In contrast, the EEG is a record
Traditional means of lie detection, such as the polygraph, rely on measurements of peripheral nervous system (PNS) activity. Recent advances in noninvasive brain imaging techniques, such as functional magnetic resonance imaging (fMRI), have aroused public and academic interest in developing a viable alternative. This research paper briefly explains the technique of MRI and its application
