Abstract: A system and method of deception detection is disclosed wherein T trials are combined with P and I trials. Denoted as the complex trial (CT) protocol, in one embodiment, the beginning of each trial is indicated by the onset of a stimulus which is either a P or I, which remains on the display terminal for particular random (unpredictable to the subject) time period. At the expiration of the period, the stimulus remains on the screen, but is altered/augmented in some way, such as by color change. The subject has been instructed that if the color change is to green, for example, the trial is a target trial, and the subject should make a “yes” (target) response. If the color is anything else (e.g., red, blue, yellow), the subject must give a “no” (non-target) response. Accordingly, in the CT protocol, the subject must attend even more intensely than in prior 3-stimulus protocols to the probe-irrelevant attribute (i.e.

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.

Abstract: A method and system for treating a patient having a pathological condition characterized by asymmetry between brain waves measured from two locations of the scalp. The method comprises the steps of attaching a first electrode to a first scalp location of the patient and a second electrode to a second scalp location of the patient. Then, brain waves of the patient are recorded from the electrodes. These brain waves are used for the purpose of biofeedback. Specifically, the brain wave asymmetry is presented to the patient and the patient is rewarded for changing the asymmetry.

Abstract: A method for evoking an event related potential in a person in order to evaluate the person's beliefs, knowledge, attitudes, or veracity relating to certain subject matter comprising the steps of presenting the person with a series of statements or questions at least some of which relate to the subject matter, having the person make replies of affirmance or disaffirmance about each statement or question, presenting the person with a purported evaluation of the veracity of each of his replies, each of the evaluations caused to vary to present at least confirmation or disconfirmation of the replies and measuring the P3 of the person in response to the purported evaluations whereby the beliefs, knowledge, attitudes, or veracity of the person about the subject matter can be determined.
