Abstract: Audio Stimuli Recognition P300-based protocol is an EEG/ERP test for assessing memory deficit/intactness, malingering , and deception in clinical and forensic settings. Different versions of P300-based visual stimuli tests proved effective and accurate with autobiographical information experiments (Hit rate: 92-100%; Rosenfeld at al., in press). Audio Stimuli Recognition P300-based protocol, contains three types of stimuli: 1) A “Probe” (P--a relevant to the subject item (his/her Last Name), 2) “Irrelevant” (I—a last name, NOT relevant to the subject), and 3) a “Target” (T, an item with “assigned significance”). The stimuli are presented to subject through headphones. There are 7 different stimuli (last names) included in the protocol: five Irrelevant names, one Probe, and one Target. Each of the names repeats 30 times in a single test run. Subjects respond to all Irrelevants and the Probe with a left button on a two-button response box. They are instructed to press a RIGHT button when they hear a “Target” name.
