Automated audio multi-issue comparison test (AMCT) protocols for deception detection. In one exemplary embodiment, testing equipment that may include an eye tracking device, such as an infrared camera, computer, keyboard, mouse, chin rest, and audio output device (headphones or speaker) is used. A series of Agree and Disagree statements regarding issues of interest are presented to the examinee in an audio format as by text-to-speech narration. Each statement must include an introductory phrase, topic phrase and declaration phrase. As statements are presented, a neutral image is presented on a visual display, then replaced by an image prompting the examinee to provide a response when the statement concludes. The eye tracker measures and records eye movements during the test. At the conclusion, ocular-motor measures and test question responses are combined by means of a logistic regression equation to compute the probability of deception.
