Robots are predicted to serve in environments in which human honesty is important, such as the workplace, schools, and public institutions. Can the presence of a robot facilitate honest behavior? In this paper, we describe an experimental study evaluating the effects of robot social presence on people's honesty. Participants completed a perceptual task, which is structured so as to allow them to earn more money by not complying with the experiment instructions. We compare three conditions between subjects: Completing the task alone in a room; completing it with a non-monitoring human present; and completing it with a non-monitoring robot present. The robot is a new expressive social head capable of 4-DoF head movement and screen-based eye animation, specifically designed and built for this research. It was designed to convey social presence, but not monitoring. We find that people cheat in all three conditions, but cheat equally less when there is a human or a robot in the room, compared to when they are alone. We did not find differences in the perceived authority of the human and the robot, but did find that people felt significantly less guilty after cheating in the presence of a robot as compared to a human. This has implications for the use of robots in monitoring and supervising tasks in environments in which honesty is key.

Constructive design research is a form of research where design activity is a central research activity. One type of constructive design research is critical design, which seeks to disrupt or transgress social and cultural norms. Critical design's advocates have turned to critical theory as an intellectual resource to support their approach. Interestingly, critical design processes remain under-articulated in the growing design research literature. In this paper, we first explain why critical design is so hard to describe as a design practice or process. We then describe two critical design case studies we undertook and the effects we observed them having when place in the field. After sharing our breakdowns and breakthroughs along the way, we offer reflections on designing for provocativeness, the value of deep relationships between researchers and research participants, and the need to plan for and go with a fluid and emergent research plan --- with the goal of helping clarify critical design as an approach.

Creating and sustaining rapport between robots and people is critical for successful robotic services. As a first step towards this goal, we explored a personalization strategy with a snack delivery robot. We designed a social robotic snack delivery service, and, for half of the participants, personalized the service based on participants' service usage and interactions with the robot. The service ran for each participant for two months. We evaluated this strategy during a 4-month field experiment. The results show that, as compared with the social service alone, adding personalized service improved rapport, cooperation, and engagement with the robot during service encounters.
