Abstract:
In an EEG study of event—related potentials(REP),40 healthy volunteers partici-pated in a preliminary experiment for lie detection.This experiment required the subjects to answerwhether recognize some one in a random photo—showing.A positive rate of 95% and a false negativerate of 5% were found in this experiment.The amplitudes and area of P_(300) were proved,though prelimi-nary,to serve as an objective ground for lie detection no matter what the answer the subject made.
