In this work we investigate the effects of robot appearance and reliability on a user’s trust levels through an experiment where participants reacted to three different robot forms that either behaved reliably or unreliably during a series of experimental trials. A final trial was implemented to evaluate use choice by allowing participants to choose their preferred robot and complete an additional trial with that robot. Results from this pilot experimentation indicated differences based on the reliability of the robot, as well as whether the participant chose to interact with the robot.

Insider Threat (IT) is a growing cybersecurity issue. Countermeasures based on cognitive engineering may utilize diagnostic eye fixation responses indicative of insider intent, elicited by Active Indicator Probes (AIPs). The current study embedded AIPs into an immersive simulation of espionage activities. Participants allocated to an insider role were required to monitor building images for cues to a terrorist person-of-interest, and communicate information to an external handler. Control participants performed matched normal work. Findings confirmed a previous finding that ITs show fixation responses suggestive of strategic concealment of interest. They also showed heightened attention to communications from their local controller. These results may contribute to identification of possible ITs for further screening.
