Exploration of New Indexes of Event-Related Potentials in Polygraph
Original Abstract
Abstract
The research adopts the method of the simulation of crime situation, takes waveform deviation and wave area as the indexes, explores the EEG response of the guilty individuals and innocent individuals to target pictures, as well as familiar and unfamiliar pictures. The results show that there is no significant difference in the waveform deviation and wave area of the EEG response of the individuals of different genders to the three types of pictures; the response of the guilty individuals to the target pictures and familiar pictures is more similar; the response of the innocent individuals to target pictures and unfamiliar pictures is more similar. In the future research and practice, waveform deviation and wave area can be acted as the effective new indexes by which to examine whether an individual is guilty.
