Title
Theta Synchronization and ERPs in Deception Detection
Abstract
Although event related potentials (ERPs) have been used for the deception detection, deception-related changes in the electroencephalogram (EEG) remain to be established. The purpose of this research is to test the effect of theta oscillation in information concealing. EEG is recorded when healthy volunteers performed a deceptive task in a card-like version of the Concealed Information Test (CIT) paradigm. Data were analyzed by using event-related synchronization. A significant effect in theta power was recorded. The probe stimulus elicited larger theta synchronization than the irrelevant stimulus in the 200-500 ms post-stimulus data for deceptive participants. This effect was not observed in the control group. The theta synchronization effect overlapped with the classical ERP P300 effect but with marked difference in electrodes. The theta synchronization effect was strongest on the Fz electrode. The P300 effect was strongest on the Pz electrode. Our results indicated that theta synchronization is correlated with concealing information and might reflect some changes in related deception.
