Abstract: A method and system for testing for untruthfulness in a subject. In a testing session, at least one test stimulus is presented to the subject. The subject's brain waves are sensed from at least two locations of the subject's scalp to obtain a scaled distribution representing the subject's response to the at least one test stimulus. The distribution obtained in response to the test stimulus is compared to a similarly scaled control distribution of the subject's brain waves. The control distribution represents the brain waves sensed from the at least two locations of the subject's scalp in response to a control stimulus. The subject's truthfulness in response to the at least one test stimulus is inferred from the comparison.

Abstract: A program for detecting memory deficiency malingering in a subject. The subject is presented with a series of trials wherein each trial includes display of a sample stimulus, followed by display of a test stimulus. In some of the trials the test stimulus matches the sample stimulus and in others of the trials the test stimulus does not match the sample stimulus. The subject's brain waves are measured and recorded during at least some of the display of the test stimuli. The subject indicates with respect to at least some of the test stimuli whether the test stimulus matches or does not match the sample stimulus. Memory deficiency malingering can be determined by comparing the indication from the subject to the measured brain waves of the subject.
