This research used an Autonomous Security Robot (ASR) scenario to examine public reactions to a robot that possesses the authority and capability to inflict harm on a human. Individual differences in terms of personality and Perfect Automation Schema (PAS) were examined as predictors of trust in the ASR. Participants (N=316) from Amazon Mechanical Turk (MTurk) rated their trust of the ASR and desire to use ASRs in public and military contexts following a 2-minute video depicting the robot interacting with three research confederates. The video showed the robot using force against one of the three confederates with a non-lethal device. Results demonstrated that individual differences factors were related to trust and desired use of the ASR. Agreeableness and both facets of the PAS (high expectations and all-or-none beliefs) demonstrated unique associations with trust using multiple regression techniques. Agreeableness, intellect, and high expectations were uniquely related to desired use for both public and military domains. This study showed that individual differences influence trust and one's desired use of ASRs, demonstrating that societal reactions to ASRs may be subject to variation among individuals.

Alarcon, G. M., Gibson, A. M., Jessup, S. A..  2020.  Trust Repair in Performance, Process, and Purpose Factors of Human-Robot Trust. 2020 IEEE International Conference on Human-Machine Systems (ICHMS). :1—6.

The current study explored the influence of trust and distrust behaviors on performance, process, and purpose (trustworthiness) perceptions over time when participants were paired with a robot partner. We examined the changes in trustworthiness perceptions after trust violations and trust repair after those violations. Results indicated performance, process, and purpose perceptions were all affected by trust violations, but perceptions of process and purpose decreased more than performance following a distrust behavior. Similarly, trust repair was achieved in performance perceptions, but trust repair in perceived process and purpose was absent. When a trust violation occurred, process and purpose perceptions deteriorated and failed to recover from the violation. In addition, the trust violation resulted in untrustworthy perceptions of the robot. In contrast, trust violations decreased partner performance perceptions, and subsequent trust behaviors resulted in a trust repair. These findings suggest that people are more sensitive to distrust behaviors in their perceptions of process and purpose than they are in performance perceptions.
