Assess Ability to use Eye Tracking and Pupil Dilation to Determine Intent to Deceive

We are utilizing the output from eye trackers to develop procedures to identify momentary lapses in alertness. The intent to deceive should be associated with the converse, momentary increases in alertness. We review literature dealing with the issue of deception as reflected in: pupil diameter, saccadic eye movements, eye blinks, minor eye movements,vergence eye movements, and conjugate oculomotor activity, as well as two aspects of behavior that can be monitored with eye tracker and output from a mouse. The specific question to be investigated in this phase I effort is: Can a battery of bio-behavioral measures (identified above)successfully detect deceptive responses about personally relevant material? We describe the specifics of the experiment to be conducted. Data analytic techniques that have already been developed in our laboratory will be used to evaluate data and identify optimal measures to predict deception.
