A control question method for evaluating whether or not a subject has previously performed a given act. The subject is preliminarily questioned about the given and other unrelated acts, and then is serially repetitively presented with an odd-ball paradigm comprised of such given facts as well as irrelevant facts. Event-related potentials concurrently generated by the subject are electroencephalographically sensed and analyzed for P3 content and the P3 waves generated by each paradigm repeat are compared. Based on selected criteria, a conclusion regarding prior act performance is made. Computer means are utilized to regulate the paradigm presentation and to interpret and analyze the P3 responses.
