As social robots enter educational and public settings, understanding how children perceive and engage with them becomes crucial. This study introduces the Social Bench Tool, an interdisciplinary measure adapted from social psychology to assess children’s implicit attitudes toward robots. In the task, children choose where to sit on a bench next to a humanoid robot, revealing interpersonal orientation toward it. We tested a digital version in a pilot study with adolescents and implemented a physical version during a public event with children. Preliminary results from the digital study suggest participants sat closer to the robot after interacting with it. Observations from the physical setup support the tool’s potential as a behavioral measure in more naturalistic contexts. The Social Bench Tool offers a simple, intuitive way to complement self-reports in Child-Robot Interaction research.
