Abstract :
Current lie detection methods, based on the polygraph technique, rely upon the measurement of several physiological characteristics to discriminate whether a truth or a lie is expressed. Direct electro-encephalographic (EEG) measurements of event-related brain potentials (ERP) to particular questions or situations can also be used. The purpose of this study is to evaluate RT (Reaction Time) analysis and combined RT and ERP to identify participants is possessing specific guilty knowledge. The accuracy of BART (bootstrapped analysis of reaction time) method is 81% which are comparable to 80% accuracy of ERP analysis (Wavelet classifier method) in previous study. BART-BAD method has the best accuracy compared to multimodal methods and has superior results compared to the single mode analysis (BAD method). BAD-BART method proposed as best approach for Assess "Guilty Knowledge".
