| Research Abstract |
In the event-related brain potential (ERP)-based detection of deception studies, the most promising index in terms of practical application to the criminal investigation is the P300 component. This study examined various problems toward a practical use of the P300-based detection of deception : (1)comparing visual and auditory presentation of questions,(2)counteracting countermeasures,(3)shortening examination time,(4)developing a new multiple probe protocol, and(5)statistical procedures for evaluating the results by the protocol. Results suggest that the field applications of the detection of deception are feasible with P300 as a dependent variable.
