This research-in-progress note reports on the design and execution of a study in HCI-based deception detection. The objective of the study is to examine the impact of knowledge of tracking and countermeasures on the neuro- motor changes detected when subjects commit a malfeasant act. To examine this, an experimental context and design was required that would afford the subjects an opportunity to commit an un-sanctioned malicious act while tracking ground truth in an unobtrusive manner. The experimental design, study execution, and preliminary results are presented.
