| Abstract: | This experiment examined the accuracy and reliability of the event-related potential(ERP) for detecting information related to events that subjects have experienced.31 subjects who had been in custody for involving in criminal cases were tested with event-related potential method and the data were statistically analyzed with SSPS 11.5 software.The results showed that accuracy was 80.6% and P300 has potential as an investigative tool in criminal cases. |
