    You Did That on Purpose! An Investigation of the Knobe Effect in Human-Robot Interactions
    (2024-01-03) Kegel , Mona; Ghanem, Laid
    As robots are becoming increasingly intelligent and autonomous, situations will increase where robots make decisions that cause side-effects. To investigate humans’ intentionality judgments in these situations, this study examines the Knobe effect in human-robot interactions. The Knobe effect describes the phenomenon that the perceived goodness or badness of the side effect of actions asymmetrically influences people’s intentionality attributions. Examining three different agents (i.e., human, humanoid robot, android robot), we found a Knobe effect for the human agent and the android robot, but not for the humanoid robot. The results suggest that as robots become more human-like, the Knobe effect becomes more relevant. Furthermore, a mediation analysis shows that existing explanatory approaches of the Knobe effect cannot mediate the effect of the nature of the side effect on intentionality judgments in the android robot. This work provides important insights into the debate about robots as intentional agents.

    Influencing Incidental Human-Robot Encounters: Expressive movement improves pedestrians' impressions of a quadruped service robot
    (2024-01-03) Hauser, Elliott; Chan, Yao-Cheng; Bhalani, Ruchi; Kuchimanchi, Alekhya; Siddiqui, Hanaa; Hart, Justin
    A single mobile service robot may generate hundreds of encounters with pedestrians, yet there is little published data on the factors influencing these incidental human-robot encounters. We report the results of a between-subjects experiment (n=222) testing the impact of robot body language, defined as non-functional modifications to robot movement, upon incidental pedestrian encounters with a quadruped service robot in a real-world setting. We find that canine-inspired body language had a positive influence on participants' perceptions of the robot compared to the robot's stock movement. This effect was visible across all questions of a questionnaire on the perceptions of robots (Godspeed). We argue that body language is a promising and practical design space for improving pedestrian encounters with service robots.
