Abstract
The method of phase synchronization (PS) of chaotic is applied and the difference of electroencephalograms (EEGs) recorded from lie detection (LD) experiment between the truth and the lying responses from the two kinds of subjects is explored. In this study, the LD experiment based on the standard three stimuli protocol was designed to gather information of the twenty subjects' EEG. Phase Locking Value (PLV) was used as a statistical measure from PS for the aim of few stimulus in LD experiment. Experimental result shows first a specific spatial and temporal disparity in PS that guilty group has a stronger /higher PLV than innocent group. In particular, the result of pattern recognition---high accuracy is up to 88%. It is concluded that functional connectivity network for lie detection can help to collect more insight into the deception process. Therefore, PLV can be considered to be a valid method to identify deception and guide us to understand cognition processing with connectivity network of lie.
