The aim of concealed information test (CIT) is comparison of subject’s physiological responses in deed-related (probe) vs. irrelevant items in order to detect concealedinformation. Two types of physiological measurement which are very useful for CIT consist of peripheral physiological measure (such as electrodermal activity (EDA), phasic heartrate (PHR) and respiration rate) and event related potentials. The aim of this study is designing CIT test for simultaneousmeasurement of these two types of signals in order to increment the result of test. For evaluating the ability of detecting concealed information in this test, we assess the eventrelated potentials. In ERP assessment, BAD (bootstrapped amplitude difference) and BCD (bootstrapped correlation difference) methods were used for analysis of P300 wave.
