Detection of concealed information using event-related potentials

What is it about?

There is a considerable interest in finding methods that help us to know when a person is lying and when is telling the truth from a forensic point of view. Currently, one of the lines of research leans toward the use of event-related potentials. We intend to give a brief objective review of articles studying these procedures using different methods: properties, reliability, validity, and limitations. Results indicate success rates in discriminating the guilty in a range of 7 to 100 percent, and the not-guilty ones from 31 to 100 percent.
