BCI(Brain Computer Interface) for detecting lying

This purpose of this study was to investigate the effects of the using BCI(Brain Computer Interface) for detecting deception. the most commonly used method for detecting deception is based on the assumption that lies given by a person in response to critical questions posed during a polygraph examination will elicit an identificable pattern of autonomic reactivity. Critics of this method argue that a polygraph examination cannot detect lying because lying does not produce a distinct physiological response. They assert that the possession of information only the guilty person would be expected to have can be revealed in a polygraph examination, however, by the pattern of autonomic arousal presentation of this information elicits in a person who possessed it. In this article, the position is taken that the dependence of both procedures on autonomic measures diminishes their effectiveness and inhibits the development of alternatives. A few studies are reviewed that suggest that measures of brain electrical activity can be used to infer the possession of information in persons attempting to conceal it. Especially, the ERP(event-related brain potentials) paradigms may be a viable alternative to the polygraph for detecting deception. These components may provide very powerful indexed of the neurocognitive mechanisms that are activated by stimulus events of significance to a person, irrespective of the person's willingness to express that significance.
